Arizona is a state in the Southwestern region of the United States, sharing the Four Corners region of the western United States with Colorado, New Mexico, and Utah. Its other neighboring states are Nevada to the northwest and California to the west. It also shares an international border with the Mexican states of Sonora and Baja California to the south and southwest. It is the 6th-largest and the 14th-most-populous of the 50 states. Its capital and largest city is Phoenix, which is the most populous state capital in the United States.
Arizona is the 48th state and last of the contiguous states to be admitted to the Union, achieving statehood on February 14, 1912. Historically part of the territory of Alta California and Nuevo México in New Spain, it became part of independent Mexico in 1821. After being defeated in the Mexican–American War, Mexico ceded much of this territory to the United States in 1848, where the area became part of the territory of New Mexico. The southernmost portion of the state was acquired in 1853 through the Gadsden Purchase.
Southern Arizona is known for its desert climate, with extremely hot summers and mild winters. Northern Arizona features forests of pine, Douglas fir, and spruce trees; the Colorado Plateau; mountain ranges (such as the San Francisco Mountains); as well as large, deep canyons, with much more moderate summer temperatures and significant winter snowfalls. There are ski resorts in the areas of Flagstaff, Sunrise, and Tucson. In addition to the internationally known Grand Canyon National Park, which is one of the world's seven natural wonders, there are several national forests, national parks, and national monuments.
Arizona is home to a diverse population. About one-quarter of the state is made up of Indian reservations that serve as the home of 27 federally recognized Native American tribes, including the Navajo Nation, the largest in the state and the country, with more than 300,000 citizens. Since the 1980s, the proportion of Hispanics has grown significantly owing to migration from Mexico and Central America. A substantial portion of the population are followers of the Roman Catholic Church and the Church of Jesus Christ of Latter-day Saints. Arizona's population and economy have grown dramatically since the 1950s because of inward migration, and the state is now a major hub of the Sun Belt. Cities such as Phoenix and Tucson have developed large, sprawling suburban areas. Many large companies, such as PetSmart and Circle K, have headquarters in the state, and Arizona is home to major universities, including the University of Arizona, Arizona State University, and Northern Arizona University. The state is known for a history of conservative politicians such as Barry Goldwater and John McCain, though it has become a swing state in recent years.

Page is a city in Coconino County, Arizona, United States, near the Glen Canyon Dam and Lake Powell. As of the 2010 census, the population of the city was 7,247.
Source: en.wikipedia.org/wiki/Glen_Canyon
Glen Canyon is a natural canyon carved by a 169.6-mile (272.9 km) length of the Colorado River, mostly in southeastern and south-central Utah, in the United States. Glen Canyon starts where Narrow Canyon ends, at the confluence of the Colorado River and the Dirty Devil River. A small part of the lower end of Glen Canyon extends into northern Arizona and terminates at Lee's Ferry, near the Vermilion Cliffs. Like the Grand Canyon farther downstream, Glen Canyon is part of the immense system of canyons carved by the Colorado River and its tributaries.
In 1963, a reservoir, Lake Powell, was created by the construction of the Glen Canyon Dam, in the Arizona portion of Glen Canyon near the brand new town of Page, inundating much of Glen Canyon under water hundreds of feet in depth. Contrary to popular belief, Lake Powell was not the result of negotiations over the controversial damming of the Green River within Dinosaur National Monument at Echo Park; the Echo Park Dam proposal was abandoned due to nationwide citizen pressure on Congress to do so. The Glen Canyon Dam remains a central issue for modern environmentalist movements. Beginning in the late 1990s, the Sierra Club and other organizations renewed the call to dismantle the dam and drain Lake Powell in Lower Glen Canyon. Today, Glen Canyon and Lake Powell are managed by the U.S. Department of the Interior within Glen Canyon National Recreation Area.

Glen Canyon Dam is the second highest concrete-arch dam in the United States, second only to Hoover Dam which stands at 726 feet. The 25.16 million acre-feet of water storage capacity in Lake Powell, created by Glen Canyon Dam, serves as a ‘bank account’ of water that is drawn on in times of drought. This stored water has made it possible to successfully weather extended dry periods by sustaining the needs of cities, industries, and agriculture throughout the West.
Hydroelectric power produced by the dam’s eight generators helps meet the electrical needs of the West’s rapidly growing population. With a total capacity of 1,320 megawatts, Glen Canyon Powerplant produces around five billion kilowatt-hours of hydroelectric power annually which is distributed by the Western Area Power Administration to Wyoming, Utah, Colorado, New Mexico, Arizona, Nevada, and Nebraska. In addition, revenues from production of hydropower help fund many important environmental programs associated with Glen and Grand canyons.
The designation of Glen Canyon National Recreation Area in 1972, underscores the value and importance of the recreation benefits associated with Lake Powell and the Colorado River downstream of the dam. The recreation area is managed by the National Park Service.
Glen Canyon Dam is the key water storage unit of the Colorado River Storage Project, one of the most complex and extensive river resource developments in the world. Without it, development of the Upper Colorado River Basin states’ portion of the Colorado River would not have been possible.

The rain was coming down in buckets! It was turning parking lots into rivers... Moderate to heavy rain along with gusty southerly winds have battered the region this evening as another potent, strong storm system pushes thru...
Weather scenario & details:
It was a rainy, stormy, unsettled Sunday evening here in San Jose, CA. We already had a previous storm pound us with heavy rain and strong winds. This was a 2nd storm...and this 2nd one seemed a tad stronger than the last! Talk about a 'Miracle March'! More storm advisories were posted for the region due to the stormy weather. Certainly, all this rainfall was thanks to an ongoing atmospheric river event. The moisture and storminess from this atmospheric river event was to continue at least until Monday (March 7) or so...
Timing of the storms: The 1st storm had hit by the 1st weekend of the month, bringing heavy rain & gusty winds to our area. As we started the 2nd week, a 2nd strong(er) storm system was threatening to trigger more flooding, mudslides and treacherous traveling conditions across California. On the heels of the 1st storm, this 2nd storm was to push more stormy weather across the state. Rainfall from this 2nd storm would roughly be 1-2 inches in NorCal. Flash flooding was a concern, especially with the ground already saturated and streams running high from the 1st storm. While all this rain was to help put a dent in our drought, the copious amounts of rain falling in a short time was too much of a good thing... Looks like this was El Nino's last hurrah this winter!

This is a moderate quality photograph of the dust jacket of a used copy of this book. It is not my copy (I have one, not this one) and I did not take the photo. I'm claiming "Fair Use" for this image to illustrate the style, layout and content of the profile artwork that Profile Publications (UK) and Doubleday (USA) printed and sold in the 1960s and 70s.
The 24 pamphlets collected in a bound volume like this typically featured a page of color profiles of the subject, a single type of aircraft. Usually more than 5 instances, less than 10. Each pamphlet also contained a page with a 3 to 5 view artwork (side, top, front, (other side, bottom)) of a single example of the subject. See the previous image for a partial 3 view image example.
As a young airplane nerd, I loved these books when I discovered them in the Bremerton Public Library, Bremerton, Washington, in 1969. Only two pages, one side of one sheet of paper, were in color, The rest was black and white, all well printed, on good quality paper. There had been collections of 3 - 4 - 5 view drawings, black lines on white, white lines on black, and black objects with white details on a white background, dating back to the WWII "Guides" published in USA and UK for airplane identification and spotter-hobbyist-nerds. I started borrowing books wit line-drawing profiles and 3 views from the Public Library in Arlington, Virginia, some time after 1964.
In the 1950s, as printing of artwork at popular prices increased, 3 views in black and white "screen" reproductions also appeared. From gray-scale tone paintings or more likely from color originals, These were typically combined with side view profiles showing the general appearance of successive versions of a given design. The UK's RAF Supermarine Spitfire Mk I, II, III, V, ...VIII, IX, XII, XIV... XIX, 22 and 24 for example. Or The USA's North American Model 73, RAF Mustang Mk I, USAAF P-51, A-36, P-51A, B, C, D,...H,...K.
Aircraft in Profile's use of color on 2 pages for every type of airplane they covered raised the bar, in the 1960s. ARCO in the USA produced books of color profiles and a 3 view or two with many more pages, many more examples, but devoted to limited numbers of types, almost all military, less than 50 in total. In keeping with the UK's well known enthusiasm for multiple subjects of a type, Aircraft in Profile produced 262 pamphlets, Automobiles in Profile produced 96 (4 volumes), Cars In Profile produced 2 more bound volumes, Warships In Profile produced at least 3 bound volumes, and there were AFV (armored fighting vehicles) and Small Arms profiles as well. The Automobile, Cars and Warships series were pretty good. The format wasn't quite right for AFVs or Small Arms, or perhaps the editors and writers were less gifted.
Looks good large..... :D
With the weather moderating a littler bit Roger and I started to think about the dog park again. Rog loves the dog park. The photo below was taken a second before this one. When his eyes roll back in his head he's about to do one of his patented moves. This Rotweiler and his owner are friends and this is all in great fun. Unfortuneately we did have some other problems at the park last year. Roger ( and I unfortunately ) got skunked on a walk one morning. Despite all of out best efforts the smell takes time to completely dissipate. After the skunk hit Rog had a few issues with fighting and we had to stop going for the rest of the season. I'm hoping that his unpopular personal hygiene issues were primarily to blame for the socialization problem and this year he will get along better. We're keeping our fingers ( and toes ) crossed :DD This picture is one of the first few batches that I shot with the d-40 and I pulled it and reworked it. My son Steven took the top 2 pictures while "Learning" to use the camera.

I'm a bit ticked at Flickr at the moment because, apparently, one of my other shots in this series got my status changed from safe to moderate (after well over a year on this site, these shots were apparently what put people over the edge, lol). So, instead of asking me to change the safety setting of the offending (?) image, Flickr has made it so that every image I upload is set to Moderate (I can't even list this shot as safe). What crap.
I really don't understand how any of the images in this series are considered not "safe for a global, public audience". There is no adult subject matter in any of the shots and nothing that can't be seen in any major museum around the world (I mean for content, not quality). So how is that my images are not safe for global, public viewing when similar (and more provocative) materials are already available for global, public viewing? Geez, what's next? Are we going to slap pasties on all the Greek sculptures? God forbid someone accidentally witnesses a breast or a buttock. That would surely scar them for life.
And to whomever the person or people were that went screaming to Flickr about the safety settings on these images rather than talking to me about it - give me a break and start acting like adults. If this style of image or this subject matter isn't your cup of tea then don't open it. Don't try to get me banned from the site. At least have the intestinal fortitude to contact me and discuss your opinions of my work directly.
Ridiculous.
***Update***
Well, after going back and forth with the site, I've finally gotten my status put back to safe. It annoys me however that, after switching my status back, all of my images are still set to moderate. I now have to go and bulk moderate almost every image I've posted since there are very few images I have on here that would qualify as moderate (even by site standards). How freaking annoying and inconsiderate is that? Eeeh. Oh well.

My first experience about YNP
We entered Yellowstone NP through the eastern entrance using U.S. Route 14. It had been a moderate snow fall in the end of the first week of October, 2017. From few kilometers before reaching Yellowstone Lake, remnants of devastating wild fire were being evident. It was a shocking sight for me at the beginning and could not perceive how fire had devastated hundreds of acres of alpine forests in the valleys and atop the hills. But when I had a closer look to the floor of the forests, I was amazed by the facts how nature maintains its ecological balance! Numerous tiny siblings are growing besides the burnt and decaying logs. The future forests of the park are coming alive.
The park seemed to me the world’s finest natural laboratory and archive to study and understand all the faculties of human intellect.
The qualities of the photographs are not satisfactory, because they were taken so fast through the glass windows of our running bus. But I didn’t want to miss such life time opportunities. The overall beauties were essentially more important than technicalities, as I always believe.
Our luck didn’t favor anyway in this park trip, when our tour guide had declared a forecast for heavy snowfall next day since morning. He therefore decided to visit as many spots as possible in a single day, and not to wait for day-2. I hurried through the trails taking as many snaps as possible.
The next day heavy snowfall started since 9 am, and our guide cancelled the day-2 trip. Thanks God…we covered somehow all the spots on the first day.
I hope, you may like my Yellowstone series…
A quick overview of YNP
Yellowstone National Park is an American national park located in Wyoming, Montana, and Idaho. Approximately 96 percent of the land area of Yellowstone National Park is located within the state of Wyoming. The Park spans an area of 8,983 km2 comprising lakes, canyons, rivers and mountain ranges. The park is known for its wildlife and its many geothermal features. It has many types of ecosystems, but the subalpine forest is the most abundant. It is part of the South Central Rockies forests eco-region.
It was established by the U.S. Congress and signed into law by President Ulysses S. Grant on March 1, 1872. Yellowstone was the first national park in the U.S. and is also widely held to be the first national park in the world. Native Americans have lived in the Yellowstone region for at least 11,000 years. Aside from visits by mountain -men during the early to mid-19th century, organized exploration did not begin until the late 1860s.
The park contains the headwaters of the Yellowstone River, from which it takes its historical name. Although it is commonly believed that the river was named for the yellow rocks seen in the ‘Grand Canyon of the Yellowstone’, the Native American name source is unclear.
Yellowstone Lake is one of the largest high-elevation lakes in North America and is centered over the Yellowstone Caldera, the largest supervolcano on the continent. The caldera is considered as an active volcano. It has erupted with tremendous force several times in the last two million year. The Yellowstone Caldera is the largest volcanic system in North America. It has been termed a "supervolcano" because the caldera was formed by exceptionally large explosive eruptions. The magma chamber that lies under Yellowstone is estimated to be a single connected chamber, about 60 km long, 29 km wide, and 5 to 12 km deep. Yellowstone Lake is up to 400 feet deep and has 180 km of shoreline.The lake is at an elevation of 7,733 feet above sea levels. Half of the world's geysers and hydrothermal features are there in Yellowstone, fueled by this ongoing volcanism. Lava and rocks from volcanic eruptions cover most of the land area of Yellowstone. The park is the centerpiece of the Greater Yellowstone Ecosystem, the largest remaining nearly-intact ecosystem in the Earth's northern temperate zone. In 1978, Yellowstone was named a UNESCO World Heritage Site.
In May 2001, the U.S. Geological Survey, Yellowstone National Park, and the University of Utah created the Yellowstone Volcano Observatory (YVO), a partnership for long-term monitoring of the geological processes of the Yellowstone Plateau volcanic field, for disseminating information concerning the potential hazards of this geologically active region.
Hundreds of species of mammals, birds, fish, and reptiles have been documented, including several that are either endangered or threatened. The vast forests and grasslands also include unique species of plants. Yellowstone Park is the largest and most famous mega fauna location in the contiguous United States. Grizzly bears, wolves, and free-ranging herds of bison and elk live in this park. The Yellowstone Park bison herd is the oldest and largest public bison herd in the United States.
Forest fires occur in the park each year. In the largest forest fires of 1988, nearly one third of the park was burnt.
Yellowstone has numerous recreational opportunities, including hiking, camping, boating, fishing and sightseeing. Paved roads provide close access to the major geothermal areas as well as some of the lakes and waterfalls. During the winter, visitors often access the park by way of guided tours that use either snow coaches or snowmobiles.
Fire in Yellowstone NP:
Causes of wildfire in Yellowstone NP
Wildfire has had a role in the dynamics of Yellowstone’s ecosystems for thousands of years. Although many fires were caused by human activities, most ignitions were natural. The term "natural ignition" usually refers to a lightning strike. Afternoon thunderstorms occur frequently in the northern Rocky Mountains but release little precipitation, a condition known as ‘dry lightning’. In a typical season there are thousands of lightning strikes in Yellowstone. Lightning strikes are powerful enough to rip strips of bark off of a tree in a shower of sparks and blow the pieces up to 100 feet away. However, most lightning strikes do not result in a wildfire because fuels are not in a combustible state.
The great fire incidence of 1988
The Yellowstone fires of 1988 collectively formed the largest wildfire in the recorded history of Yellowstone National Park in the United States. Starting as many smaller individual fires, the flames quickly spread out of control due to drought conditions and increasing winds, combining into one large conflagration which burned for several months. The fires almost destroyed two major visitor destinations and, on September 8, 1988, the entire park closed to all non-emergency personnel for the first time in its history. Only the arrival of cool and moist weather in the late autumn brought the fires to an end. A total of 793,880 acres, or 36 percent of the park was affected by the wildfires.
Fire incidence, 2016
As of September 21, 2016, 22 fires (human and lightning-caused) have burned more than 62,000 acres in Yellowstone National Park, making it the highest number of acres burned since the historic 1988 fire.
Heritage and Research Center
The Heritage and Research Center is located at Gardiner, Montana, near the north entrance to the park. The center is home to the Yellowstone National Park's museum collection, archives, research library, historian, archeology lab, and herbarium. The Yellowstone National Park Archives maintain collections of historical records of Yellowstone and the National Park Service. The collection includes the administrative records of Yellowstone, as well as resource management records, records from major projects, and donated manuscripts and personal papers. The archives are affiliated with the National Archives and Records Administration.
Geothermal features of Yellowstone NP- A brief note:
There are four geothermal features found in the park – Hot springs, Geysers, Fumaroles , and Mud volcanoes/pots.
What is a Hot spring?
Hot spring, also called thermal spring, spring with water at temperatures substantially higher than the air temperature of the surrounding region. Most hot springs discharge groundwater that is heated by shallow intrusions of magma (molten rock) in volcanic areas.
Some thermal springs, however, are not related to volcanic activity. In general, the temperature of rocks within the earth increases with depth. The rate of temperature increase with depth is known as the geothermal gradient. In such cases, the water is heated by convective circulation: groundwater percolating downward reaches depths of a kilometre or more where the temperature of rocks is high because of the normal temperature gradient of the Earth’s crust—about 30 °C / kilometer in the first 10 km. The water from hot springs in non-volcanic areas is heated in this manner.
But in active volcanic zones such as Yellowstone National Park, water may be heated by coming into contact with magma (molten rock). The high temperature gradient near magma may cause water to be heated enough that it boils or becomes superheated. If the water becomes so hot that it builds steam pressure and erupts in a jet above the surface of the Earth, it is called a geyser.
[ Warm springs are sometimes the result of hot and cold springs mixing. They may occur within a volcanic area or outside of one. One example of a non-volcanic warm spring is Warm Springs, Georgia (frequented for its therapeutic effects by paraplegic U.S. President Franklin D. Roosevelt, who built the Little White House there) ].
List of hot springs:
[ en.wikipedia.org/wiki/List_of_hot_springs ]
The science of colors of a hot spring:
[ ttps://www.britannica.com/science/hot-spring]
Many of the colours in hot springs are caused by thermophilic (heat-loving) microorganisms, which include certain types of bacteria, such as cyanobacteria, and species of archaea and algae. Many thermophilic organisms grow in huge colonies called mats that form the colourful scums and slimes on the sides of hot springs. The microorganisms that grow in hot springs derive their energy from various chemicals and metals; potential energy sources include molecular hydrogen, dissolved sulfides, methane, iron, ammonia, and arsenic. In addition to geochemistry, the temperature and pH of hot springs play a central role in determining which organisms inhabit them.
Examples of thermophilic microorganisms found in hot springs include bacteria in the genera Sulfolobus, which can grow at temperatures of up to 90 °C (194 °F), Hydrogenobacter, which grow optimally at temperatures of 85 °C (185 °F), and Thermocrinis, which grow optimally at temperatures of 80 °C (176 °F). Thermophilic algae in hot springs are most abundant at temperatures of 55 °C (131 °F) or below.
What is a Geyser?
A geyser is formed when water collecting below the surface is heated by a magma source. When the water boils, it rises to the surface. If the water has an unobstructed path, it will pool on the surface in the form of a steaming hot springs. If the passage of the water is imposed upon, the pressure will increase. When the pressure becomes too great, the water converts into to steam. Steam takes up 1,500 times the volume of water, and at this point, the pressure becomes so intense that the steam and surrounding water droplets shoot out of the ground in geyser form, erupting until the pressure has abated and the process starts all over again.
What is a fumarole?
It’s a vent in the Earth’s surface from which steam and volcanic gases are emitted. The major source of the water vapour emitted by fumaroles is groundwater heated by bodies of magma lying relatively close to the surface. Carbon dioxide, sulfur dioxide, and hydrogen sulfide are usually emitted directly from the magma. Fumaroles are often present on active volcanoes during periods of relative quiet between eruptions.
Fumaroles are closely related to hot springs and geysers. In areas where the water table rises near the surface, fumaroles can become hot springs. A fumarole rich in sulfur gases is called a solfatara; a fumarole rich in carbon dioxide is called a mofette. If the hot water of a spring only reaches the surface in the form of steam, it is called a fumarole. [ www.britannica.com/science/fumarole ]
What is a mud volcano/ mud pot/ paint pot?-
Usually mud volcanoes are created by hot-spring activity where large amounts of gas and small amounts of water react chemically with the surrounding rocks and form a boiling mud.
Geo-chemistry of mud volcano: Hydrogen sulfide gas rising from magma chamber, as in Yellowstone’s, causes the rotten-egg smell. Microorganisms, or thermophiles, use this gas as a source of energy, and then help turn the gas into sulfuric acid. The acid then breaks down the rocks and soil into mud. Many of the colors seen are vast communities of thermophiles, but some of the yellow is pure sulfur. When iron mixes with sulfur to form iron sulfide, gray and black swirls sometimes appear in the mud (From description of the display board in the park).
If the water of a hot spring is mixed with mud and clay, it is called a mud pot. Variations are the porridge pot (a basin of boiling mud that erodes chunks of the surrounding rock) and the paint pot (a basin of boiling mud that is tinted yellow, green, or blue by minerals from the surrounding rocks).
There are other mud volcanoes, entirely of a nonigneous origin, occur only in oil-field regions that are relatively young and have soft, unconsolidated formations.

Hello/Goodbye
Flickr Censors: GO FUCK YOURSELVES
Flickr Friends: I'm shopping around for either a free website, or a new photo-sharing site. When I get settled, I'll let you know where to find me. I plan on stripping my site of all but a few of my images, so that I lose none when my Pro Account expires.
I appreciate the camaraderie and the feedback I've received over the years - but I refuse to participate in the Flickr Censorship Bullshit Dance.
For now, I'm posting on Ipernity:

Flickr is now officially useless to me. Goodbye
I have been through this so many times with Flickr, in the past.
My images have been thouroughly scrutinized by FLickr.
The "offending" icon survived ALL assessments by Flickr, until complaints from an image thief. (see forwarded message below.) The Flickr icon is a photo of a doll, wearing shorts sitting on a toilet thinking. Nothing sexual. Nothing involving bodily functions. Nothing that needs banning or it would have been dealt with through the many previous inspections of my account. It has been up as long as I've had my account.
This obsessed image thief is filing vexatious complaints all over the internet, and Flickr is now participating by restricting my account. If there is something new loaded since my Flickr police inspections, I apologize, BUT I HIGHLY DOUBT IT.
I was thinking of closing my Flickr account because of the CONSTANT THEFT OF MY IMAGES. This hassle takes far too much of my time. The image thief you are catering to has promised to steal my images again and to post them again.
If Flickr would prefer I leave, then leave my account restricted.
I will not stay with a restricted account.
I HAVE TOO MANY IMAGES TO GO THROUGH TO MEET ANOTHER ARBITRARY HARASSMENT.
I'VE DONE IT TOO MANY TIMES FOR ME TO NEED TO DO IT AGAIN.
NOTHING NEW HAS BEEN ADDED SINCE MY LAST ASSESSMENT TO WARRANT THIS NEW RESTRICTION.
If there is a specific image that crossed community guidelines, please let me know, because I have been very careful not to offend your sensitive guidelines, the most restricting of all photo sites I am involved with.
The thank you I get from Flickr, for my years of PAYING for your service and posting great award winning photography is to restrict my account when an angry image thief complains about me because he got caught stealing my images from YOUR WEBSITE.

Oh, I'm not really worried for it at all. Sometimes I have moderate to severe Facetious Behavior Compulsion Disorder. I think it is moderately terminal. I just think it is weird and humorous how almost every ailment or disease known is described on TV commercials as moderate to severe. When I grew up people that had a headache just said they had a headache, or a migraine, or a horrible or a really bad headache. They didn't use the cumbersome wording and legalese of "moderate to severe." These days they have new moderate to severely lengthy names, and acronyms and can provide, mostly severely, but not too many moderately priced pills, if you are willing to risk the "moderate to severe side effects."
Oh, and I don't consider death a side effect. Side effect to me seems like something that occurs along side of the beneficial things the pill/s are doing. Death pretty much ends anything else going on along side of it.

Yellowstone Falls consist of two major waterfalls on the Yellowstone River, within Yellowstone NP. As the Yellowstone river flows north from Yellowstone Lake, it leaves the Hayden Valley and plunges first over Upper Yellowstone Falls and then a quarter mile (400 m) downstream over Lower Yellowstone Falls, at which point it then enters the Grand Canyon of the Yellowstone, which is up to 1,000 feet deep.
A quick overview of YNP
Yellowstone National Park is an American national park located in Wyoming, Montana, and Idaho. Approximately 96 percent of the land area of Yellowstone National Park is located within the state of Wyoming. The Park spans an area of 8,983 km2 comprising lakes, canyons, rivers and mountain ranges. The park is known for its wildlife and its many geothermal features. It has many types of ecosystems, but the subalpine forest is the most abundant. It is part of the South Central Rockies forests eco-region.
It was established by the U.S. Congress and signed into law by President Ulysses S. Grant on March 1, 1872. Yellowstone was the first national park in the U.S. and is also widely held to be the first national park in the world. Native Americans have lived in the Yellowstone region for at least 11,000 years. Aside from visits by mountain -men during the early to mid-19th century, organized exploration did not begin until the late 1860s.
The park contains the headwaters of the Yellowstone River, from which it takes its historical name. Although it is commonly believed that the river was named for the yellow rocks seen in the ‘Grand Canyon of the Yellowstone’, the Native American name source is unclear.
Yellowstone Lake is one of the largest high-elevation lakes in North America and is centered over the Yellowstone Caldera, the largest supervolcano on the continent. The caldera is considered as an active volcano. It has erupted with tremendous force several times in the last two million year. The Yellowstone Caldera is the largest volcanic system in North America. It has been termed a "supervolcano" because the caldera was formed by exceptionally large explosive eruptions. The magma chamber that lies under Yellowstone is estimated to be a single connected chamber, about 60 km long, 29 km wide, and 5 to 12 km deep. Yellowstone Lake is up to 400 feet deep and has 180 km of shoreline.The lake is at an elevation of 7,733 feet above sea levels. Half of the world's geysers and hydrothermal features are there in Yellowstone, fueled by this ongoing volcanism. Lava and rocks from volcanic eruptions cover most of the land area of Yellowstone. The park is the centerpiece of the Greater Yellowstone Ecosystem, the largest remaining nearly-intact ecosystem in the Earth's northern temperate zone. In 1978, Yellowstone was named a UNESCO World Heritage Site.
In May 2001, the U.S. Geological Survey, Yellowstone National Park, and the University of Utah created the Yellowstone Volcano Observatory (YVO), a partnership for long-term monitoring of the geological processes of the Yellowstone Plateau volcanic field, for disseminating information concerning the potential hazards of this geologically active region.
Hundreds of species of mammals, birds, fish, and reptiles have been documented, including several that are either endangered or threatened. The vast forests and grasslands also include unique species of plants. Yellowstone Park is the largest and most famous mega fauna location in the contiguous United States. Grizzly bears, wolves, and free-ranging herds of bison and elk live in this park. The Yellowstone Park bison herd is the oldest and largest public bison herd in the United States.
Forest fires occur in the park each year. In the largest forest fires of 1988, nearly one third of the park was burnt.
Yellowstone has numerous recreational opportunities, including hiking, camping, boating, fishing and sightseeing. Paved roads provide close access to the major geothermal areas as well as some of the lakes and waterfalls. During the winter, visitors often access the park by way of guided tours that use either snow coaches or snowmobiles.
Fire in Yellowstone NP:
Causes of wildfire in Yellowstone NP
Wildfire has had a role in the dynamics of Yellowstone’s ecosystems for thousands of years. Although many fires were caused by human activities, most ignitions were natural. The term "natural ignition" usually refers to a lightning strike. Afternoon thunderstorms occur frequently in the northern Rocky Mountains but release little precipitation, a condition known as ‘dry lightning’. In a typical season there are thousands of lightning strikes in Yellowstone. Lightning strikes are powerful enough to rip strips of bark off of a tree in a shower of sparks and blow the pieces up to 100 feet away. However, most lightning strikes do not result in a wildfire because fuels are not in a combustible state.
The great fire incidence of 1988
The Yellowstone fires of 1988 collectively formed the largest wildfire in the recorded history of Yellowstone National Park in the United States. Starting as many smaller individual fires, the flames quickly spread out of control due to drought conditions and increasing winds, combining into one large conflagration which burned for several months. The fires almost destroyed two major visitor destinations and, on September 8, 1988, the entire park closed to all non-emergency personnel for the first time in its history. Only the arrival of cool and moist weather in the late autumn brought the fires to an end. A total of 793,880 acres, or 36 percent of the park was affected by the wildfires.
Fire incidence, 2016
As of September 21, 2016, 22 fires (human and lightning-caused) have burned more than 62,000 acres in Yellowstone National Park, making it the highest number of acres burned since the historic 1988 fire.
Heritage and Research Center
The Heritage and Research Center is located at Gardiner, Montana, near the north entrance to the park. The center is home to the Yellowstone National Park's museum collection, archives, research library, historian, archeology lab, and herbarium. The Yellowstone National Park Archives maintain collections of historical records of Yellowstone and the National Park Service. The collection includes the administrative records of Yellowstone, as well as resource management records, records from major projects, and donated manuscripts and personal papers. The archives are affiliated with the National Archives and Records Administration.
Geothermal features of Yellowstone NP- A brief note:
There are four geothermal features found in the park – Hot springs, Geysers, Fumaroles , and Mud volcanoes/pots.
What is a Hot spring?
Hot spring, also called thermal spring, spring with water at temperatures substantially higher than the air temperature of the surrounding region. Most hot springs discharge groundwater that is heated by shallow intrusions of magma (molten rock) in volcanic areas.
Some thermal springs, however, are not related to volcanic activity. In general, the temperature of rocks within the earth increases with depth. The rate of temperature increase with depth is known as the geothermal gradient. In such cases, the water is heated by convective circulation: groundwater percolating downward reaches depths of a kilometre or more where the temperature of rocks is high because of the normal temperature gradient of the Earth’s crust—about 30 °C / kilometer in the first 10 km. The water from hot springs in non-volcanic areas is heated in this manner.
But in active volcanic zones such as Yellowstone National Park, water may be heated by coming into contact with magma (molten rock). The high temperature gradient near magma may cause water to be heated enough that it boils or becomes superheated. If the water becomes so hot that it builds steam pressure and erupts in a jet above the surface of the Earth, it is called a geyser.
[ Warm springs are sometimes the result of hot and cold springs mixing. They may occur within a volcanic area or outside of one. One example of a non-volcanic warm spring is Warm Springs, Georgia (frequented for its therapeutic effects by paraplegic U.S. President Franklin D. Roosevelt, who built the Little White House there) ].
List of hot springs:
[ en.wikipedia.org/wiki/List_of_hot_springs ]
The science of colors of a hot spring:
[ ttps://www.britannica.com/science/hot-spring]
Many of the colours in hot springs are caused by thermophilic (heat-loving) microorganisms, which include certain types of bacteria, such as cyanobacteria, and species of archaea and algae. Many thermophilic organisms grow in huge colonies called mats that form the colourful scums and slimes on the sides of hot springs. The microorganisms that grow in hot springs derive their energy from various chemicals and metals; potential energy sources include molecular hydrogen, dissolved sulfides, methane, iron, ammonia, and arsenic. In addition to geochemistry, the temperature and pH of hot springs play a central role in determining which organisms inhabit them.
Examples of thermophilic microorganisms found in hot springs include bacteria in the genera Sulfolobus, which can grow at temperatures of up to 90 °C (194 °F), Hydrogenobacter, which grow optimally at temperatures of 85 °C (185 °F), and Thermocrinis, which grow optimally at temperatures of 80 °C (176 °F). Thermophilic algae in hot springs are most abundant at temperatures of 55 °C (131 °F) or below.
What is a Geyser?
A geyser is formed when water collecting below the surface is heated by a magma source. When the water boils, it rises to the surface. If the water has an unobstructed path, it will pool on the surface in the form of a steaming hot springs. If the passage of the water is imposed upon, the pressure will increase. When the pressure becomes too great, the water converts into to steam. Steam takes up 1,500 times the volume of water, and at this point, the pressure becomes so intense that the steam and surrounding water droplets shoot out of the ground in geyser form, erupting until the pressure has abated and the process starts all over again.
What is a fumarole?
It’s a vent in the Earth’s surface from which steam and volcanic gases are emitted. The major source of the water vapour emitted by fumaroles is groundwater heated by bodies of magma lying relatively close to the surface. Carbon dioxide, sulfur dioxide, and hydrogen sulfide are usually emitted directly from the magma. Fumaroles are often present on active volcanoes during periods of relative quiet between eruptions.
Fumaroles are closely related to hot springs and geysers. In areas where the water table rises near the surface, fumaroles can become hot springs. A fumarole rich in sulfur gases is called a solfatara; a fumarole rich in carbon dioxide is called a mofette. If the hot water of a spring only reaches the surface in the form of steam, it is called a fumarole. [ www.britannica.com/science/fumarole ]
What is a mud volcano/ mud pot/ paint pot?-
Usually mud volcanoes are created by hot-spring activity where large amounts of gas and small amounts of water react chemically with the surrounding rocks and form a boiling mud.
Geo-chemistry of mud volcano: Hydrogen sulfide gas rising from magma chamber, as in Yellowstone’s, causes the rotten-egg smell. Microorganisms, or thermophiles, use this gas as a source of energy, and then help turn the gas into sulfuric acid. The acid then breaks down the rocks and soil into mud. Many of the colors seen are vast communities of thermophiles, but some of the yellow is pure sulfur. When iron mixes with sulfur to form iron sulfide, gray and black swirls sometimes appear in the mud (From description of the display board in the park).
If the water of a hot spring is mixed with mud and clay, it is called a mud pot. Variations are the porridge pot (a basin of boiling mud that erodes chunks of the surrounding rock) and the paint pot (a basin of boiling mud that is tinted yellow, green, or blue by minerals from the surrounding rocks).
There are other mud volcanoes, entirely of a nonigneous origin, occur only in oil-field regions that are relatively young and have soft, unconsolidated formations.

My first experience about YNP
We entered Yellowstone NP through the eastern entrance using U.S. Route 14. It had been a moderate snow fall in the end of the first week of October, 2017. From few kilometers before reaching Yellowstone Lake, remnants of devastating wild fire were being evident. It was a shocking sight for me at the beginning and could not perceive how fire had devastated hundreds of acres of alpine forests in the valleys and atop the hills. But when I had a closer look to the floor of the forests, I was amazed by the facts how nature maintains its ecological balance! Numerous tiny siblings are growing besides the burnt and decaying logs. The future forests of the park are coming alive.
The park seemed to me the world’s finest natural laboratory and archive to study and understand all the faculties of human intellect.
The qualities of the photographs are not satisfactory, because they were taken so fast through the glass windows of our running bus. But I didn’t want to miss such life time opportunities. The overall beauties were essentially more important than technicalities, as I always believe.
Our luck didn’t favor anyway in this park trip, when our tour guide had declared a forecast for heavy snowfall next day since morning. He therefore decided to visit as many spots as possible in a single day, and not to wait for day-2. I hurried through the trails taking as many snaps as possible.
The next day heavy snowfall started since 9 am, and our guide cancelled the day-2 trip. Thanks God…we covered somehow all the spots on the first day.
I hope, you may like my Yellowstone series…

Working my way through the heat of the southwest with the Xpan, with the moderate width 35mm PC Nikkor with zone focusing. This was the first roll with the new bulk roll of Arista Ultra 100, so used the standard (for me) Rodinal/Xtol combo for developing. There seems to be more grain than before, despite using the same conditions. Nonetheless, the latitude was about the same. Not sure if I want to try another EI100 film like ORWO or the pricey TMAX. My favorite mid-speed film is Neopan, but it's now NeopanII, subcontracted to Ilford, and just isn't the same. More to discover. Thanks again to the artists who continue to inspire with their efforts.

The Fountain of Putti is a monumental work in Carrara marble , located at the entrance to Piazza dei Miracoli and Via Santa Maria in Pisa .
It was built between 1746 and 1765 by Giuseppe Vaccà , who took care of the base, and by Giovanni Antonio Cybei , author of the marble group of putti holding the coats of arms of Pisa and the Opera del Duomo, based on a design by the painter Giovanni Battista Tempesti
The presence of a first fountain in the Piazza del Duomo, although simple and devoid of ornaments, has been attested since 1659. However, it was thanks to the Operaio dell'Opera Francesco Quarantotti , appointed in 1729, that the current structure was built , strategically moved a few meters compared to the position of the previous fountain and placed "on the corner of the paved road that goes to the church" , that is, in front of the exit of via Santa Maria into Piazza del Duomo. For the new monument, an aesthetic solution was chosen that could better harmonize with the classic appearance of the monuments in the square .
The first phase of construction of the fountain was entrusted to the Carrara sculptor Giuseppe Vaccà, who had participated together with his father Giovan Battista and his cousin in the furnishing of the Cathedral , a phase which ended in 1746 with the construction of a base decorated with cherubs and acanthus leaves. The pillar of the source was built in Avenza di Massa in the Vaccà workshop in just under a year, and despite the construction difficulties caused by the soft ground (which it was necessary to consolidate by driving 33 pine poles deep) , in September by 1746 the fountain could now be said to be completed . Its creation, as reported in the Memoria del Duomo by Filippo D'Angelo, was defined as "not magnifying but beautiful and gallant" .
In 1763 Anton Francesco Maria Quarantotti, who had succeeded his father in the service of the Opera del Duomo, agreed with Vaccà to complete the structure of the fountain with a sculptural group to be positioned above the marble base. Vaccà in all likelihood in this case only played the role of entrepreneur : the construction was in fact entrusted to Giovanni Antonio Cybei , who worked starting from a preparatory drawing by the painter Giovanni Battista Tempesti . From 1763, the work kept Cybei busy for about two years ; the sculptural group was transported to the city by sea and up the Arno a few days before Christmas 1765
Shortly after the completion of the work, the first critical assessments also emerged, which were directed in particular against the sculptural group of the three putti. The oldest written testimony of these negative judgments dates back to Filippo D'Angelo , who, in his Memoirs of the Cathedral and events of the city of Pisa in 1767 , defined the author as "a terrible statuary" .
In 1848, the Pisan sculptor Girolamo Marconi was the first to propose replacing the sculptural group with a statue of the city's patron saint, San Ranieri , also replacing the base with another, more sober one, bearing the city coat of arms [9] . However, probably due to lack of funds, the proposal was not followed up .
With the foundation in Pisa of the Association for the embellishments of the Piazza del Duomo (1862), born in the period of national unification, the hypothesis of replacing the group of three putti, judged to be of little value, with the statue of Buscheto , architect of the Cathedral . However, not even this time did the intent to restore a more austere appearance to the square lead to concrete results.
The opportunity for a new attempt to remove the group presented itself with the appointment of Archbishop Pietro Maffi in 1905. Maffi, who was an astronomer and had been appointed president of the Vatican Observatory in 1904 , proposed replacing the putti with a monument to Galileo Galilei . To reduce costs, he also suggested removing only the sculptural group, using the fountain below. The project, however, was harshly criticized when it was made public in 1906; on this occasion, for the first time, some defenders of the Fontana dei Putti intervened as a historical and symbolic element of the square. The determination of Maffi, who in the meantime had become cardinal, led him to a second attempt in 1922, when the Genoese sculptor Antonio Bozzano was entrusted with the task of creating a sketch for the work . Once again, however, the project was not successful: the survival of the Fontana dei Putti was probably guaranteed by the failure of Maffi to be elected to the papal throne in the Council of 1922 , which instead led to the election of Achille Ratti with the name of Pope Pius XI. This event marked the end of a century of replacement projects and allowed the three cherubs to maintain their role among the prominent monuments in the square.
The history of the attribution of the sculptural group of the three putti has been the subject of complex developments.
Despite the relevant testimony of Girolamo Tiraboschi , who already in 1786, in his biography dedicated to Cybei, mentioned among the artist's works the three putti in the Piazza del Duomo of Pisa , over time the name of the author of group was lost.
In 1873 Tiraboschi's words were also reported by the Marquis Giovanni Campori in his Biographical Memoirs of sculptors, architects, painters, etc. natives of the Province of Massa in 1873 , but despite this testimony for a long time the role of Cybei was ignored and the sculptures were attributed to Giuseppe Vaccà. The attribution to Vaccà also remained in the Pisa Guide by Bellini Pietri and in a 1931 essay by Giorgio Castelfranco entitled The Fountain of G. Vaccà in Piazza del Duomo in Pisa.
Subsequently, in 1990, Paolo Roberto Ciardi seemed to resolve the issue by publishing the contract stipulated in 1763 between the Worker Quarantotti and Giuseppe Vaccà, which recognized the latter as the author of the three putti. However, towards the end of the nineties, the discovery of an autograph by Cybei, in which the sculptor explicitly declared that he had created the group for the fountain, allowed the paternity of the work to be returned to him
The base created by Giuseppe Vaccà appears as a parallelepiped positioned vertically, characterized on two sides by acanthus leaves, which create a bulge in the lower part of the plinth, while, on the opposite sides, two volutes resting on a base support the basin for the 'waterfall.
In the areas of the squares of the fountain's pedestal the artist is inspired by the architectural formulas of the sixteenth and seventeenth centuries, proposing an architecture animated by two different themes: on two sides, a geometric ornamentation; on the other two, mythological figures in high relief. The artist also uses different techniques for the two pairs of panels: high relief for the figurative images and low relief for the more ornamental decoration .
In the squares of the parallelepiped, the artist creates a dialogue between art and nature , representing an acanthus leaf that invades the lower part of the base, a symbol widely used in architectural decorative resolutions. The artist here clearly refers to classical models [19] , loading them with allusive values: the acanthus leaf, a constant presence on capitals, ceiling and wall decorations, returns here to symbolize freshness and refreshment, themes that are well suited to the nature and function of the monument.
The considerable volume of acanthus leaves also has its own structural utility . It distributes the weight thrusts at the base of the parallelepiped towards the ground in a more uniform and less incidental way, avoiding the formation of cracks and ensuring better cohesion between the different parts. To confirm this, we observe the presence of two overturned shelves under the two basins, which also serve to balance the downward forces.
In the other two areas of the panels, however, the work is loaded with allegorical-symbolic values through one of the most traditional figures of mythological language: the Triton who fights with the sea monster. The extremely popular theme, however, seems to refer in particular to a preparatory drawing by Marco da Faenza for the grotesques of the Triton in combat, preserved at the superintendence for artistic and historical heritage of Florence .
The young Tritons, represented in a mirrored manner in the mirrors of the base, have the aim of enhancing the wonder of the sea. One, by blowing the conch, seems to attract the attention of the other intent on fighting, immortalized in the gesture of throwing a stone at the monster subjected to him, in a playful and carefree atmosphere. The volumes of the figures burst into space, projecting to the maximum, with a powerful modeling that goes beyond the limits of high relief.
The sculptural group created between 1763 and 1765 by Antonio Cybei is located above the base and depicts three colossal putti, also in white Carrara marble , holding the coats of arms of Pisa and the Opera del Duomo .
In his reworking of the work, Cybei did not modify the poses of the three putti compared to the original sketch proposed by Tempesti, but inverted the central putto counterclockwise, creating a composition capable of further highlighting the dynamism of the figures.
The spiral arrangement of the figures had the aim of lightening the base and, at the same time, creating the optical illusion of an ascending movement, as if the direction given to the movement was not directed downwards, but was going towards the sky . The different compositional arrangement between Tempesti's sketch and Cybei's work highlights a different intent. In Tempesti's sketch, which is arranged clockwise, the shield seems to move downwards, as if it descended directly from the sky into the arms of the children . On the contrary, in the layout given by Cybei the figures are positioned counterclockwise, with the statues appearing to raise the shield upwards, in a gesture "of thanksgiving and consecration of the Pisan people to God".
In this sense, the execution of Tempesti's modeling still has a baroque character, in which the composition rotates around a central axis, and the distribution of weights moves in a spiral that converges downwards. On the contrary, the change made by Cybei, with the anti-clockwise movement of the figures, seems to mark, according to Mario Noferi, the transition from baroque to rococo . In fact, the revision, which proposed an ascending dynamism in the form of a spiral, seems to lighten the weight of the compositions that characterizes baroque works while maintaining the basic principles of representation intact, in line with one of the main objectives of the Rococo. In summary, the reworking of Cybei made the work more modern compared to Tempesti's sketch, which still reflected the influence of the Roman school .
Another notable characteristic of the Putti group is certainly the plastic treatment of the volumes, capable of expressing the sensation of the softness of the flesh. The skilful use of chiaroscuro also contributes to this rendering, which gives the sculpture an almost pictorial character, to the point of pushing Mario Noferi to believe that "the sculptor, with intention, wanted to leave traces of the original design idea taken from the drawing of a painter". Evidence of these plastic abilities would also be, according to the scholar, the careful reproduction of an atmospheric phenomenon: the disheveled hair of the children, in fact, seems to be agitated by the wind, a re-enactment of a natural phenomenon that contributes to the overall movement of the work
From a symbolic point of view, the presence of water refers to the concept of purification, historically also referring to the dawn of Christianity, when fountains were placed in the atrium of Christian basilicas to introduce the sacred space. In the same way it would then be possible, according to Mario Noferi, to consider the monumental fountain as a spiritual entrance to the square, at the convergence of all the city streets that lead to the Cathedral.
Furthermore, according to the scholar, the iconic buildings of the square symbolize the essential phases of human life in relation to faith: birth represented by the baptistery, life symbolized by the cathedral and death evoked by the cemetery. Similarly, the three lively children who adorn the top of the Fountain represent a specific phase of human existence, recalling the short period of childhood characterized by energy and recklessness in games
The introduction of postal cards is believed to have contributed to the revaluation of the fountain in the 19th century . Initially, in fact, the classic view of the square included only the Baptistery, the Cathedral and the famous Leaning Tower. However, as time passed, the fountain was included in other images taken from different angles, acquiring a significant role among other major monuments and arousing the interest of both postcard buyers and the recipients themselves .
This process gradually led the fountain to establish itself in the collective imagination as an essential element of the urban panorama of the Piazza dei Miracoli. However, it is with the advent of mobile devices and new technologies that the fountain has taken on an even more relevant role. Today, thanks to the ease with which it is possible to take photographs and videos, the fountain is included in many images of the square, deliberately chosen to offer added value to the image itself and enhance the other monuments present.
Furthermore, a notable aspect is that from the perspective located at the intersection between Piazza dei Miracoli and Via Santa Maria, it is possible to appreciate in a single glance all three faces of the children who, with their different contortions, support the coat of arms of the city of Pisa .
Ultimately, the fountain on the Piazza dei Miracoli has undergone a process of revaluation over the years, becoming a fundamental element of the urban landscape. Thanks to social media, its presence is increasingly constantly documented, while the peculiar detail of the cherubs holding up the coat of arms of Pisa contributes to increasing the curiosity and attention of visitors
The Fountain of Putti also appears in the theme song of the fourth animated season of " Lupine III - The Italian Adventure ", a derivative of the manga by the Japanese cartoonist Monkey Punch and broadcast in 2015 .
The series, made up of twenty-six episodes, is entirely set in Italy and the opening theme features several important Italian tourist places (such as Rome, the canals of Venice, San Marino, Santa Maria del Fiore in Florence). Among these, a significant shot is reserved for the Leaning Tower of Pisa, with the Fountain of the Putti placed right in the foreground.
Pisa is a city and comune in Tuscany, central Italy, straddling the Arno just before it empties into the Ligurian Sea. It is the capital city of the Province of Pisa. Although Pisa is known worldwide for its leaning tower, the city contains more than twenty other historic churches, several medieval palaces, and bridges across the Arno. Much of the city's architecture was financed from its history as one of the Italian maritime republics.
The city is also home to the University of Pisa, which has a history going back to the 12th century, the Scuola Normale Superiore di Pisa, founded by Napoleon in 1810, and its offshoot, the Sant'Anna School of Advanced Studies.
History
For a chronological guide, see Timeline of Pisa.
Ancient times
The most believed hypothesis is that the origin of the name Pisa comes from Etruscan and means 'mouth', as Pisa is at the mouth of the Arno river.
Although throughout history there have been several uncertainties about the origin of the city of Pisa, excavations made in the 1980s and 1990s found numerous archaeological remains, including the fifth century BC tomb of an Etruscan prince, proving the Etruscan origin of the city, and its role as a maritime city, showing that it also maintained trade relations with other Mediterranean civilizations.
Ancient Roman authors referred to Pisa as an old city. Virgil, in his Aeneid, states that Pisa was already a great center by the times described; and gives the epithet of Alphēae to the city because it was said to have been founded by colonists from Pisa in Elis, near which the Alpheius river flowed. The Virgilian commentator Servius wrote that the Teuti founded the town 13 centuries before the start of the common era.
The maritime role of Pisa should have been already prominent if the ancient authorities ascribed to it the invention of the naval ram. Pisa took advantage of being the only port along the western coast between Genoa (then a small village) and Ostia. Pisa served as a base for Roman naval expeditions against Ligurians and Gauls. In 180 BC, it became a Roman colony under Roman law, as Portus Pisanus. In 89 BC, Portus Pisanus became a municipium. Emperor Augustus fortified the colony into an important port and changed the name to Colonia Iulia obsequens.
Pisa supposedly was founded on the shore, but due to the alluvial sediments from the Arno and the Serchio, whose mouth lies about 11 km (7 mi) north of the Arno's, the shore moved west. Strabo states that the city was 4.0 km (2.5 mi) away from the coast. Currently, it is located 9.7 km (6 mi) from the coast. However, it was a maritime city, with ships sailing up the Arno. In the 90s AD, a baths complex was built in the city.
Late Antiquity and Early Middle Ages
During the last years of the Western Roman Empire, Pisa did not decline as much as the other cities of Italy, probably due to the complexity of its river system and its consequent ease of defence. In the seventh century, Pisa helped Pope Gregory I by supplying numerous ships in his military expedition against the Byzantines of Ravenna: Pisa was the sole Byzantine centre of Tuscia to fall peacefully in Lombard hands, through assimilation with the neighbouring region where their trading interests were prevalent. Pisa began in this way its rise to the role of main port of the Upper Tyrrhenian Sea and became the main trading centre between Tuscany and Corsica, Sardinia, and the southern coasts of France and Spain.
After Charlemagne had defeated the Lombards under the command of Desiderius in 774, Pisa went through a crisis, but soon recovered. Politically, it became part of the duchy of Lucca. In 860, Pisa was captured by vikings led by Björn Ironside. In 930, Pisa became the county centre (status it maintained until the arrival of Otto I) within the mark of Tuscia. Lucca was the capital but Pisa was the most important city, as in the middle of tenth century Liutprand of Cremona, bishop of Cremona, called Pisa Tusciae provinciae caput ("capital of the province of Tuscia"), and a century later, the marquis of Tuscia was commonly referred to as "marquis of Pisa". In 1003, Pisa was the protagonist of the first communal war in Italy, against Lucca. From the naval point of view, since the ninth century, the emergence of the Saracen pirates urged the city to expand its fleet; in the following years, this fleet gave the town an opportunity for more expansion. In 828, Pisan ships assaulted the coast of North Africa. In 871, they took part in the defence of Salerno from the Saracens. In 970, they gave also strong support to Otto I's expedition, defeating a Byzantine fleet in front of Calabrese coasts.
11th century
The power of Pisa as a maritime nation began to grow and reached its apex in the 11th century, when it acquired traditional fame as one of the four main historical maritime republics of Italy (Repubbliche Marinare).
At that time, the city was a very important commercial centre and controlled a significant Mediterranean merchant fleet and navy. It expanded its powers in 1005 through the sack of Reggio Calabria in the south of Italy. Pisa was in continuous conflict with some 'Saracens' - a medieval term to refer to Arab Muslims - who had their bases in Corsica, for control of the Mediterranean. In 1017, Sardinian Giudicati were militarily supported by Pisa, in alliance with Genoa, to defeat the Saracen King Mugahid, who had settled a logistic base in the north of Sardinia the year before. This victory gave Pisa supremacy in the Tyrrhenian Sea. When the Pisans subsequently ousted the Genoese from Sardinia, a new conflict and rivalry was born between these major marine republics. Between 1030 and 1035, Pisa went on to defeat several rival towns in Sicily and conquer Carthage in North Africa. In 1051–1052, the admiral Jacopo Ciurini conquered Corsica, provoking more resentment from the Genoese. In 1063, Admiral Giovanni Orlandi, coming to the aid of the Norman Roger I, took Palermo from the Saracen pirates. The gold treasure taken from the Saracens in Palermo allowed the Pisans to start the building of their cathedral and the other monuments which constitute the famous Piazza del Duomo.
In 1060, Pisa had to engage in their first battle with Genoa. The Pisan victory helped to consolidate its position in the Mediterranean. Pope Gregory VII recognised in 1077 the new "Laws and customs of the sea" instituted by the Pisans, and emperor Henry IV granted them the right to name their own consuls, advised by a council of elders. This was simply a confirmation of the present situation, because in those years, the marquis had already been excluded from power. In 1092, Pope Urban II awarded Pisa the supremacy over Corsica and Sardinia, and at the same time raising the town to the rank of archbishopric.
Pisa sacked the Tunisian city of Mahdia in 1088. Four years later, Pisan and Genoese ships helped Alfonso VI of Castilla to push El Cid out of Valencia. A Pisan fleet of 120 ships also took part in the First Crusade, and the Pisans were instrumental in the taking of Jerusalem in 1099. On their way to the Holy Land, the ships did not miss the occasion to sack some Byzantine islands; the Pisan crusaders were led by their archbishop Daibert, the future patriarch of Jerusalem. Pisa and the other Repubbliche Marinare took advantage of the crusade to establish trading posts and colonies in the Eastern coastal cities of the Levant. In particular, the Pisans founded colonies in Antiochia, Acre, Jaffa, Tripoli, Tyre, Latakia, and Accone. They also had other possessions in Jerusalem and Caesarea, plus smaller colonies (with lesser autonomy) in Cairo, Alexandria, and of course Constantinople, where the Byzantine Emperor Alexius I Comnenus granted them special mooring and trading rights. In all these cities, the Pisans were granted privileges and immunity from taxation, but had to contribute to the defence in case of attack. In the 12th century, the Pisan quarter in the eastern part of Constantinople had grown to 1,000 people. For some years of that century, Pisa was the most prominent commercial and military ally of the Byzantine Empire, overcoming Venice itself.
12th century
In 1113, Pisa and Pope Paschal II set up, together with the count of Barcelona and other contingents from Provence and Italy (Genoese excluded), a war to free the Balearic Islands from the Moors; the queen and the king of Majorca were brought in chains to Tuscany. Though the Almoravides soon reconquered the island, the booty taken helped the Pisans in their magnificent programme of buildings, especially the cathedral, and Pisa gained a role of pre-eminence in the Western Mediterranean.
In the following years, the powerful Pisan fleet, led by archbishop Pietro Moriconi, drove away the Saracens after ferocious battles. Though short-lived, this Pisan success in Spain increased the rivalry with Genoa. Pisa's trade with Languedoc, Provence (Noli, Savona, Fréjus, and Montpellier) were an obstacle to Genoese interests in cities such as Hyères, Fos, Antibes, and Marseille.
The war began in 1119 when the Genoese attacked several galleys on their way home to the motherland, and lasted until 1133. The two cities fought each other on land and at sea, but hostilities were limited to raids and pirate-like assaults.
In June 1135, Bernard of Clairvaux took a leading part in the Council of Pisa, asserting the claims of Pope Innocent II against those of Pope Anacletus II, who had been elected pope in 1130 with Norman support, but was not recognised outside Rome. Innocent II resolved the conflict with Genoa, establishing Pisan and Genoese spheres of influence. Pisa could then, unhindered by Genoa, participate in the conflict of Innocent II against king Roger II of Sicily. Amalfi, one of the maritime republics (though already declining under Norman rule), was conquered on August 6, 1136; the Pisans destroyed the ships in the port, assaulted the castles in the surrounding areas, and drove back an army sent by Roger from Aversa. This victory brought Pisa to the peak of its power and to a standing equal to Venice. Two years later, its soldiers sacked Salerno.
New city walls, erected in 1156 by Consul Cocco Griffi
In the following years, Pisa was one of the staunchest supporters of the Ghibelline party. This was much appreciated by Frederick I. He issued in 1162 and 1165 two important documents, with these grants: Apart from the jurisdiction over the Pisan countryside, the Pisans were granted freedom of trade in the whole empire, the coast from Civitavecchia to Portovenere, a half of Palermo, Messina, Salerno and Naples, the whole of Gaeta, Mazara, and Trapani, and a street with houses for its merchants in every city of the Kingdom of Sicily. Some of these grants were later confirmed by Henry VI, Otto IV, and Frederick II. They marked the apex of Pisa's power, but also spurred the resentment of other cities such as Lucca, Massa, Volterra, and Florence, thwarting their aim to expand towards the sea. The clash with Lucca also concerned the possession of the castle of Montignoso and mainly the control of the Via Francigena, the main trade route between Rome and France. Last, but not least, such a sudden and large increase of power by Pisa could only lead to another war with Genoa.
Genoa had acquired a dominant position in the markets of southern France. The war began in 1165 on the Rhône, when an attack on a convoy, directed to some Pisan trade centres on the river, by the Genoese and their ally, the count of Toulouse, failed. Pisa, though, was allied to Provence. The war continued until 1175 without significant victories. Another point of attrition was Sicily, where both the cities had privileges granted by Henry VI. In 1192, Pisa managed to conquer Messina. This episode was followed by a series of battles culminating in the Genoese conquest of Syracuse in 1204. Later, the trading posts in Sicily were lost when the new Pope Innocent III, though removing the excommunication cast over Pisa by his predecessor Celestine III, allied himself with the Guelph League of Tuscany, led by Florence. Soon, he stipulated[clarification needed] a pact with Genoa, too, further weakening the Pisan presence in southern Italy.
To counter the Genoese predominance in the southern Tyrrhenian Sea, Pisa strengthened its relationship with its traditional Spanish and French bases (Marseille, Narbonne, Barcelona, etc.) and tried to defy the Venetian rule of the Adriatic Sea. In 1180, the two cities agreed to a nonaggression treaty in the Tyrrhenian and the Adriatic, but the death of Emperor Manuel Comnenus in Constantinople changed the situation. Soon, attacks on Venetian convoys were made. Pisa signed trade and political pacts with Ancona, Pula, Zara, Split, and Brindisi; in 1195, a Pisan fleet reached Pola to defend its independence from Venice, but the Serenissima soon reconquered the rebel sea town.
One year later, the two cities signed a peace treaty, which resulted in favourable conditions for Pisa, but in 1199, the Pisans violated it by blockading the port of Brindisi in Apulia. In the following naval battle, they were defeated by the Venetians. The war that followed ended in 1206 with a treaty in which Pisa gave up all its hopes to expand in the Adriatic, though it maintained the trading posts it had established in the area. From that point on, the two cities were united against the rising power of Genoa and sometimes collaborated to increase the trading benefits in Constantinople.
13th century
In 1209 in Lerici, two councils for a final resolution of the rivalry with Genoa were held. A 20-year peace treaty was signed, but when in 1220, the emperor Frederick II confirmed his supremacy over the Tyrrhenian coast from Civitavecchia to Portovenere, the Genoese and Tuscan resentment against Pisa grew again. In the following years, Pisa clashed with Lucca in Garfagnana and was defeated by the Florentines at Castel del Bosco. The strong Ghibelline position of Pisa brought this town diametrically against the Pope, who was in a dispute with the Holy Roman Empire, and indeed the pope tried to deprive Pisa of its dominions in northern Sardinia.
In 1238, Pope Gregory IX formed an alliance between Genoa and Venice against the empire, and consequently against Pisa, too. One year later, he excommunicated Frederick II and called for an anti-Empire council to be held in Rome in 1241. On May 3, 1241, a combined fleet of Pisan and Sicilian ships, led by the emperor's son Enzo, attacked a Genoese convoy carrying prelates from northern Italy and France, next to the isle of Giglio (Battle of Giglio), in front of Tuscany; the Genoese lost 25 ships, while about a thousand sailors, two cardinals, and one bishop were taken prisoner. After this major victory, the council in Rome failed, but Pisa was excommunicated. This extreme measure was only removed in 1257. Anyway, the Tuscan city tried to take advantage of the favourable situation to conquer the Corsican city of Aleria and even lay siege to Genoa itself in 1243.
The Ligurian republic of Genoa, however, recovered fast from this blow and won back Lerici, conquered by the Pisans some years earlier, in 1256.
The great expansion in the Mediterranean and the prominence of the merchant class urged a modification in the city's institutes. The system with consuls was abandoned, and in 1230, the new city rulers named a capitano del popolo ("people's chieftain") as civil and military leader. Despite these reforms, the conquered lands and the city itself were harassed by the rivalry between the two families of Della Gherardesca and Visconti. In 1237 the archbishop and the Emperor Frederick II intervened to reconcile the two rivals, but the strains continued. In 1254, the people rebelled and imposed 12 Anziani del Popolo ("People's Elders") as their political representatives in the commune. They also supplemented the legislative councils, formed of noblemen, with new People's Councils, composed by the main guilds and by the chiefs of the People's Companies. These had the power to ratify the laws of the Major General Council and the Senate.
Decline
The decline is said to have begun on August 6, 1284, when the numerically superior fleet of Pisa, under the command of Albertino Morosini, was defeated by the brilliant tactics of the Genoese fleet, under the command of Benedetto Zaccaria and Oberto Doria, in the dramatic naval Battle of Meloria. This defeat ended the maritime power of Pisa and the town never fully recovered; in 1290, the Genoese destroyed forever the Porto Pisano (Pisa's port), and covered the land with salt. The region around Pisa did not permit the city to recover from the loss of thousands of sailors from the Meloria, while Liguria guaranteed enough sailors to Genoa. Goods, however, continued to be traded, albeit in reduced quantity, but the end came when the Arno started to change course, preventing the galleys from reaching the city's port up the river. The nearby area also likely became infested with malaria. The true end came in 1324, when Sardinia was entirely lost to the Aragonese.
Always Ghibelline, Pisa tried to build up its power in the course of the 14th century, and even managed to defeat Florence in the Battle of Montecatini (1315), under the command of Uguccione della Faggiuola. Eventually, however, after a long siege, Pisa was occupied by Florentines in 1405.[9] Florentines corrupted the capitano del popolo ("people's chieftain"), Giovanni Gambacorta, who at night opened the city gate of San Marco. Pisa was never conquered by an army. In 1409, Pisa was the seat of a council trying to set the question of the Great Schism. In the 15th century, access to the sea became more difficult, as the port was silting up and was cut off from the sea. When in 1494, Charles VIII of France invaded the Italian states to claim the Kingdom of Naples, Pisa reclaimed its independence as the Second Pisan Republic.
The new freedom did not last long; 15 years of battles and sieges by the Florentine troops led by Antonio da Filicaja, Averardo Salviati and Niccolò Capponi were made, but they failed to conquer the city. Vitellozzo Vitelli with his brother Paolo were the only ones who actually managed to break the strong defences of Pisa and make a breach in the Stampace bastion in the southern west part of the walls, but he did not enter the city. For that, they were suspected of treachery and Paolo was put to death. However, the resources of Pisa were getting low, and at the end, the city was sold to the Visconti family from Milan and eventually to Florence again. Livorno took over the role of the main port of Tuscany. Pisa acquired a mainly cultural role spurred by the presence of the University of Pisa, created in 1343, and later reinforced by the Scuola Normale Superiore di Pisa (1810) and Sant'Anna School of Advanced Studies (1987).
Pisa was the birthplace of the important early physicist Galileo Galilei. It is still the seat of an archbishopric. Besides its educational institutions, it has become a light industrial centre and a railway hub. It suffered repeated destruction during World War II.
Since the early 1950s, the US Army has maintained Camp Darby just outside Pisa, which is used by many US military personnel as a base for vacations in the area.
Geography
Climate
Pisa has a borderline humid subtropical climate (Köppen climate classification: Cfa) and Mediterranean climate (Köppen climate classification: Csa). The city is characterized by cool to mild winters and hot summers. This transitional climate allows Pisa to have summers with moderate rainfall. Rainfall peaks in autumn. Snow is rare. The highest officially recorded temperature was 39.5 °C (103.1 °F) on 22 August 2011 and the lowest was −13.8 °C (7.2 °F) on 12 January 1985.
Culture
Gioco del Ponte
In Pisa there was a festival and game fr:Gioco del Ponte (Game of the Bridge) which was celebrated (in some form) in Pisa from perhaps the 1200s down to 1807. From the end of the 1400s the game took the form of a mock battle fought upon Pisa's central bridge (Ponte di Mezzo). The participants wore quilted armor and the only offensive weapon allowed was the targone, a shield-shaped, stout board with precisely specified dimensions. Hitting below the belt was not allowed. Two opposing teams started at opposite ends of the bridge. The object of the two opposing teams was to penetrate, drive back, and disperse the opponents' ranks and to thereby drive them backwards off the bridge. The struggle was limited to forty-five minutes. Victory or defeat was immensely important to the team players and their partisans, but sometimes the game was fought to a draw and both sides celebrated.
In 1677 the battle was witnessed by Dutch travelling artist Cornelis de Bruijn. He wrote:
"While I stayed in Livorno, I went to Pisa to witness the bridge fight there. The fighters arrived fully armored, wearing helmets, each carrying their banner, which was planted at both ends of the bridge, which is quite wide and long. The battle is fought with certain wooden implements made for this purpose, which they wear over their arms and are attached to them, with which they pummel each other so intensely that I saw several of them carried away with bloody and crushed heads. Victory consists of capturing the bridge, in the same way as the fistfights in Venice between the it:Castellani and the Nicolotti."
In 1927 the tradition was revived by college students as an elaborate costume parade. In 1935 Vittorio Emanuele III with the royal family witnessed the first revival of a modern version of the game, which has been pursued in the 20th and 21st centuries with some interruptions and varying degrees of enthusiasm by Pisans and their civic institutions.

Main sights
The Leaning Tower of Pisa.
While the bell tower of the cathedral, known as "the leaning Tower of Pisa", is the most famous image of the city, it is one of many works of art and architecture in the city's Piazza del Duomo, also known, since the 20th century, as Piazza dei Miracoli (Square of Miracles), to the north of the old town center. The Piazza del Duomo also houses the Duomo (the Cathedral), the Baptistry and the Campo Santo (the monumental cemetery). The medieval complex includes the above-mentioned four sacred buildings, the hospital and few palaces. All the complex is kept by the Opera (fabrica ecclesiae) della Primaziale Pisana, an old non profit foundation that has operated since the building of the Cathedral in 1063 to maintain the sacred buildings. The area is framed by medieval walls kept by the municipal administration.
Other sights include:
Santo Stefano dei Cavalieri, church sited on Piazza dei Cavalieri, and also designed by Vasari. It had originally a single nave; two more were added in the 17th century. It houses a bust by Donatello, and paintings by Vasari, Jacopo Ligozzi, Alessandro Fei, and Pontormo. It also contains spoils from the many naval battles between the Cavalieri (Knights of St. Stephan) and the Turks between the 16th and 18th centuries, including the Turkish battle pennant hoisted from Ali Pacha's flagship at the 1571 Battle of Lepanto.
St. Sixtus. This small church, consecrated in 1133, is also close to the Piazza dei Cavalieri. It was used as a seat of the most important notarial deeds of the town, also hosting the Council of Elders. It is today one of the best preserved early Romanesque buildings in town.
St. Francis. The church of San Francesco may have been designed by Giovanni di Simone, built after 1276. In 1343 new chapels were added and the church was elevated. It has a single nave and a notable belfry, as well as a 15th-century cloister. It houses works by Jacopo da Empoli, Taddeo Gaddi and Santi di Tito. In the Gherardesca Chapel are buried Ugolino della Gherardesca and his sons.
San Frediano. This church, built by 1061, has a basilica interior with three aisles, with a crucifix from the 12th century. Paintings from the 16th century were added during a restoration, including works by Ventura Salimbeni, Domenico Passignano, Aurelio Lomi, and Rutilio Manetti.
San Nicola. This medieval church built by 1097, was enlarged between 1297 and 1313 by the Augustinians, perhaps by the design of Giovanni Pisano. The octagonal belfry is from the second half of the 13th century. The paintings include the Madonna with Child by Francesco Traini (14th century) and St. Nicholas Saving Pisa from the Plague (15th century). Noteworthy are also the wood sculptures by Giovanni and Nino Pisano, and the Annunciation by Francesco di Valdambrino.
Santa Maria della Spina. A small white marble church alongside the Arno, is attributed to Lupo di Francesco (1230), is another excellent Gothic building.
San Paolo a Ripa d'Arno. The church was founded around 952 and enlarged in the mid-12th century along lines similar to those of the cathedral. It is annexed to the Romanesque Chapel of St. Agatha, with an unusual pyramidal cusp or peak.
San Pietro in Vinculis. Known as San Pierino, it is an 11th-century church with a crypt and a cosmatesque mosaic on the floor of the main nave.
Borgo Stretto. This medieval borgo or neighborhood contains strolling arcades and the Lungarno, the avenues along the river Arno. It includes the Gothic-Romanesque church of San Michele in Borgo (990). There are at least two other leaning towers in the city, one at the southern end of central Via Santa Maria, the other halfway through the Piagge riverside promenade.
Medici Palace. The palace was once a possession of the Appiano family, who ruled Pisa in 1392–1398. In 1400 the Medici acquired it, and Lorenzo de' Medici sojourned here.
Orto botanico di Pisa. The botanical garden of the University of Pisa is Europe's oldest university botanical garden.
Palazzo Reale. The ("Royal Palace"), once belonged to the Caetani patrician family. Here Galileo Galilei showed to Grand Duke of Tuscany the planets he had discovered with his telescope. The edifice was erected in 1559 by Baccio Bandinelli for Cosimo I de Medici, and was later enlarged including other palaces. The palace is now a museum.
Palazzo Gambacorti. This palace is a 14th-century Gothic building, and now houses the offices of the municipality. The interior shows frescoes boasting Pisa's sea victories.
Palazzo Agostini. The palace is a Gothic building also known as Palazzo dell'Ussero, with its 15th-century façade and remains of the ancient city walls dating back to before 1155. The name of the building comes from the coffee rooms of Caffè dell'Ussero, historic meeting place founded on September 1, 1775.
Mural Tuttomondo. A modern mural, the last public work by Keith Haring, on the rear wall of the convent of the Church of Sant'Antonio, painted in June 1989.

For a fun interlude, this is an alternative image based off of one of my popular pics posted here on flickr in the last year+. This particular image was done with the help of the FaceApp application, where I took a photo of the original "2002-September pic-3c" pic I've posted here, then just applied a rather moderate filter. This was done to help for example with the graininess or the poor lighting in the original, to enhance the makeup a tad, and to have some fun. What do you think? How do I look? :-)
A Moderate Risk across the Plains (mainly for hail) was too much to pass up on coincident with a day off. A severe weather day that looked increasingly less robust (storm-wise) as it got closer, I ended up on a storm outside Wichita after hoping storms would fire along an OFB that set up south of a Newton-Emporia line from early morning storms. I chose to ignore the WF as I figured congestion on the roads would be awful. When it looked like storms in my area would get messy quick, I bailed to a tornado warned storm approaching ICT.
The tornado warning was dropped by the time I got to it. I wanted to get closer but later reports of 2" hail approximately 3 miles to my west made me glad I didn't.
At least I got Braum's before having to drive through torrential rain along KTA back to KC.
Mineral Ridge, Mineral Ridge (131, 19, 33) - Moderate
Welcome to Mineral Ridge, a town once booming in the mining industry a now eerie place to visit. Come explore the unknown because the biggest fear in life is the fear of not knowing what lurks around the corner or just a few feet down the street.
Rainy weather has made driving hazardous this afternoon. Moderate to heavy rains have occurred. I miss this weather... It feels like it's been forever since I've seen rain!
Weather scenario/details:
At last, rain was finally making a return to California after a very dry February! Certainly, we were in for a lot of it! Although we were still in a drought, all this rain equals hazardous conditions... It may be too much of a good thing...
Here's a weather rundown: Why the sudden rains? An atmospheric river event was in store for California for early March 2016... Despite a very dry and mild February, a major pattern change toward a much wetter weather pattern was imminent. The 1st strong system of the series had hit by the first weekend of the month, bringing heavy rain, gusty winds, and heavy mountain snow. Wind & flood advisories were also issued with the first system of the series. The 1st system's strong cold front had approached the Bay Area by Saturday afternoon. Strong southerly winds have developed as the front passed thru. While this rain was to help replenish depleted water reservoirs and put a dent in the long-standing drought, the large amount of rain in a short time frame would lead to flooding and mudslides. Despite its drawbacks, the rainfall was beneficial to the state's water supply. Impacts from the 1st strong system had brought heavy rain & wind to my area in San Jose, CA. The 2nd system was expected to arrive by Sunday night and into Monday. At the time, the 2nd system appeared a bit stronger, bringing in more heavy rain, according to forecasters. Looks like this was El Nino's last hurrah this winter! Is a 'Miracle-March' imminent? Drive safe & stay dry out there, guys.

Moderate thunderstorms nearby produced several waves over a 1 hour period of rare for this area [central Ohio] of Asperatus Clouds on Oct 25, 2024. I took 2 videos and took dozens of photos from all 3 waves of these odd clouds.
Ardana (Greek: Άρδανα, Turkish: Ardahan) is a village in Cyprus, located 9 km north of Trikomo. It is under the de facto control of Northern Cyprus.
Northern Cyprus, officially the Turkish Republic of Northern Cyprus (TRNC), is a de facto state that comprises the northeastern portion of the island of Cyprus. It is recognised only by Turkey, and its territory is considered by all other states to be part of the Republic of Cyprus.
Northern Cyprus extends from the tip of the Karpass Peninsula in the northeast to Morphou Bay, Cape Kormakitis and its westernmost point, the Kokkina exclave in the west. Its southernmost point is the village of Louroujina. A buffer zone under the control of the United Nations stretches between Northern Cyprus and the rest of the island and divides Nicosia, the island's largest city and capital of both sides.
A coup d'état in 1974, performed as part of an attempt to annex the island to Greece, prompted the Turkish invasion of Cyprus. This resulted in the eviction of much of the north's Greek Cypriot population, the flight of Turkish Cypriots from the south, and the partitioning of the island, leading to a unilateral declaration of independence by the north in 1983. Due to its lack of recognition, Northern Cyprus is heavily dependent on Turkey for economic, political and military support.
Attempts to reach a solution to the Cyprus dispute have been unsuccessful. The Turkish Army maintains a large force in Northern Cyprus with the support and approval of the TRNC government, while the Republic of Cyprus, the European Union as a whole, and the international community regard it as an occupation force. This military presence has been denounced in several United Nations Security Council resolutions.
Northern Cyprus is a semi-presidential, democratic republic with a cultural heritage incorporating various influences and an economy that is dominated by the services sector. The economy has seen growth through the 2000s and 2010s, with the GNP per capita more than tripling in the 2000s, but is held back by an international embargo due to the official closure of the ports in Northern Cyprus by the Republic of Cyprus. The official language is Turkish, with a distinct local dialect being spoken. The vast majority of the population consists of Sunni Muslims, while religious attitudes are mostly moderate and secular. Northern Cyprus is an observer state of ECO and OIC under the name "Turkish Cypriot State", PACE under the name "Turkish Cypriot Community", and Organization of Turkic States with its own name.
Several distinct periods of Cypriot intercommunal violence involving the two main ethnic communities, Greek Cypriots and Turkish Cypriots, marked mid-20th century Cyprus. These included the Cyprus Emergency of 1955–59 during British rule, the post-independence Cyprus crisis of 1963–64, and the Cyprus crisis of 1967. Hostilities culminated in the 1974 de facto division of the island along the Green Line following the Turkish invasion of Cyprus. The region has been relatively peaceful since then, but the Cyprus dispute has continued, with various attempts to solve it diplomatically having been generally unsuccessful.
Cyprus, an island lying in the eastern Mediterranean, hosted a population of Greeks and Turks (four-fifths and one-fifth, respectively), who lived under British rule in the late nineteenth-century and the first half of the twentieth-century. Christian Orthodox Church of Cyprus played a prominent political role among the Greek Cypriot community, a privilege that it acquired during the Ottoman Empire with the employment of the millet system, which gave the archbishop an unofficial ethnarch status.
The repeated rejections by the British of Greek Cypriot demands for enosis, union with Greece, led to armed resistance, organised by the National Organization of Cypriot Struggle, or EOKA. EOKA, led by the Greek-Cypriot commander George Grivas, systematically targeted British colonial authorities. One of the effects of EOKA's campaign was to alter the Turkish position from demanding full reincorporation into Turkey to a demand for taksim (partition). EOKA's mission and activities caused a "Cretan syndrome" (see Turkish Resistance Organisation) within the Turkish Cypriot community, as its members feared that they would be forced to leave the island in such a case as had been the case with Cretan Turks. As such, they preferred the continuation of British colonial rule and then taksim, the division of the island. Due to the Turkish Cypriots' support for the British, EOKA's leader, Georgios Grivas, declared them to be enemies. The fact that the Turks were a minority was, according to Nihat Erim, to be addressed by the transfer of thousands of Turks from mainland Turkey so that Greek Cypriots would cease to be the majority. When Erim visited Cyprus as the Turkish representative, he was advised by Field Marshal Sir John Harding, the then Governor of Cyprus, that Turkey should send educated Turks to settle in Cyprus.
Turkey actively promoted the idea that on the island of Cyprus two distinctive communities existed, and sidestepped its former claim that "the people of Cyprus were all Turkish subjects". In doing so, Turkey's aim to have self-determination of two to-be equal communities in effect led to de jure partition of the island.[citation needed] This could be justified to the international community against the will of the majority Greek population of the island. Dr. Fazil Küçük in 1954 had already proposed Cyprus be divided in two at the 35° parallel.
Lindley Dan, from Notre Dame University, spotted the roots of intercommunal violence to different visions among the two communities of Cyprus (enosis for Greek Cypriots, taksim for Turkish Cypriots). Also, Lindlay wrote that "the merging of church, schools/education, and politics in divisive and nationalistic ways" had played a crucial role in creation of havoc in Cyprus' history. Attalides Michael also pointed to the opposing nationalisms as the cause of the Cyprus problem.
By the mid-1950's, the "Cyprus is Turkish" party, movement, and slogan gained force in both Cyprus and Turkey. In a 1954 editorial, Turkish Cypriot leader Dr. Fazil Kuchuk expressed the sentiment that the Turkish youth had grown up with the idea that "as soon as Great Britain leaves the island, it will be taken over by the Turks", and that "Turkey cannot tolerate otherwise". This perspective contributed to the willingness of Turkish Cypriots to align themselves with the British, who started recruiting Turkish Cypriots into the police force that patrolled Cyprus to fight EOKA, a Greek Cypriot nationalist organisation that sought to rid the island of British rule.
EOKA targeted colonial authorities, including police, but Georgios Grivas, the leader of EOKA, did not initially wish to open up a new front by fighting Turkish Cypriots and reassured them that EOKA would not harm their people. In 1956, some Turkish Cypriot policemen were killed by EOKA members and this provoked some intercommunal violence in the spring and summer, but these attacks on policemen were not motivated by the fact that they were Turkish Cypriots.
However, in January 1957, Grivas changed his policy as his forces in the mountains became increasingly pressured by the British Crown forces. In order to divert the attention of the Crown forces, EOKA members started to target Turkish Cypriot policemen intentionally in the towns, so that Turkish Cypriots would riot against the Greek Cypriots and the security forces would have to be diverted to the towns to restore order. The killing of a Turkish Cypriot policeman on 19 January, when a power station was bombed, and the injury of three others, provoked three days of intercommunal violence in Nicosia. The two communities targeted each other in reprisals, at least one Greek Cypriot was killed and the British Army was deployed in the streets. Greek Cypriot stores were burned and their neighbourhoods attacked. Following the events, the Greek Cypriot leadership spread the propaganda that the riots had merely been an act of Turkish Cypriot aggression. Such events created chaos and drove the communities apart both in Cyprus and in Turkey.
On 22 October 1957 Sir Hugh Mackintosh Foot replaced Sir John Harding as the British Governor of Cyprus. Foot suggested five to seven years of self-government before any final decision. His plan rejected both enosis and taksim. The Turkish Cypriot response to this plan was a series of anti-British demonstrations in Nicosia on 27 and 28 January 1958 rejecting the proposed plan because the plan did not include partition. The British then withdrew the plan.
In 1957, Black Gang, a Turkish Cypriot pro-taksim paramilitary organisation, was formed to patrol a Turkish Cypriot enclave, the Tahtakale district of Nicosia, against activities of EOKA. The organisation later attempted to grow into a national scale, but failed to gain public support.
By 1958, signs of dissatisfaction with the British increased on both sides, with a group of Turkish Cypriots forming Volkan (later renamed to the Turkish Resistance Organisation) paramilitary group to promote partition and the annexation of Cyprus to Turkey as dictated by the Menderes plan. Volkan initially consisted of roughly 100 members, with the stated aim of raising awareness in Turkey of the Cyprus issue and courting military training and support for Turkish Cypriot fighters from the Turkish government.
In June 1958, the British Prime Minister, Harold Macmillan, was expected to propose a plan to resolve the Cyprus issue. In light of the new development, the Turks rioted in Nicosia to promote the idea that Greek and Turkish Cypriots could not live together and therefore any plan that did not include partition would not be viable. This violence was soon followed by bombing, Greek Cypriot deaths and looting of Greek Cypriot-owned shops and houses. Greek and Turkish Cypriots started to flee mixed population villages where they were a minority in search of safety. This was effectively the beginning of the segregation of the two communities. On 7 June 1958, a bomb exploded at the entrance of the Turkish Embassy in Cyprus. Following the bombing, Turkish Cypriots looted Greek Cypriot properties. On 26 June 1984, the Turkish Cypriot leader, Rauf Denktaş, admitted on British channel ITV that the bomb was placed by the Turks themselves in order to create tension. On 9 January 1995, Rauf Denktaş repeated his claim to the famous Turkish newspaper Milliyet in Turkey.
The crisis reached a climax on 12 June 1958, when eight Greeks, out of an armed group of thirty five arrested by soldiers of the Royal Horse Guards on suspicion of preparing an attack on the Turkish quarter of Skylloura, were killed in a suspected attack by Turkish Cypriot locals, near the village of Geunyeli, having been ordered to walk back to their village of Kondemenos.
After the EOKA campaign had begun, the British government successfully began to turn the Cyprus issue from a British colonial problem into a Greek-Turkish issue. British diplomacy exerted backstage influence on the Adnan Menderes government, with the aim of making Turkey active in Cyprus. For the British, the attempt had a twofold objective. The EOKA campaign would be silenced as quickly as possible, and Turkish Cypriots would not side with Greek Cypriots against the British colonial claims over the island, which would thus remain under the British. The Turkish Cypriot leadership visited Menderes to discuss the Cyprus issue. When asked how the Turkish Cypriots should respond to the Greek Cypriot claim of enosis, Menderes replied: "You should go to the British foreign minister and request the status quo be prolonged, Cyprus to remain as a British colony". When the Turkish Cypriots visited the British Foreign Secretary and requested for Cyprus to remain a colony, he replied: "You should not be asking for colonialism at this day and age, you should be asking for Cyprus be returned to Turkey, its former owner".
As Turkish Cypriots began to look to Turkey for protection, Greek Cypriots soon understood that enosis was extremely unlikely. The Greek Cypriot leader, Archbishop Makarios III, now set independence for the island as his objective.
Britain resolved to solve the dispute by creating an independent Cyprus. In 1959, all involved parties signed the Zurich Agreements: Britain, Turkey, Greece, and the Greek and Turkish Cypriot leaders, Makarios and Dr. Fazil Kucuk, respectively. The new constitution drew heavily on the ethnic composition of the island. The President would be a Greek Cypriot, and the Vice-President a Turkish Cypriot with an equal veto. The contribution to the public service would be set at a ratio of 70:30, and the Supreme Court would consist of an equal number of judges from both communities as well as an independent judge who was not Greek, Turkish or British. The Zurich Agreements were supplemented by a number of treaties. The Treaty of Guarantee stated that secession or union with any state was forbidden, and that Greece, Turkey and Britain would be given guarantor status to intervene if that was violated. The Treaty of Alliance allowed for two small Greek and Turkish military contingents to be stationed on the island, and the Treaty of Establishment gave Britain sovereignty over two bases in Akrotiri and Dhekelia.
On 15 August 1960, the Colony of Cyprus became fully independent as the Republic of Cyprus. The new republic remained within the Commonwealth of Nations.
The new constitution brought dissatisfaction to Greek Cypriots, who felt it to be highly unjust for them for historical, demographic and contributional reasons. Although 80% of the island's population were Greek Cypriots and these indigenous people had lived on the island for thousands of years and paid 94% of taxes, the new constitution was giving the 17% of the population that was Turkish Cypriots, who paid 6% of taxes, around 30% of government jobs and 40% of national security jobs.
Within three years tensions between the two communities in administrative affairs began to show. In particular disputes over separate municipalities and taxation created a deadlock in government. A constitutional court ruled in 1963 Makarios had failed to uphold article 173 of the constitution which called for the establishment of separate municipalities for Turkish Cypriots. Makarios subsequently declared his intention to ignore the judgement, resulting in the West German judge resigning from his position. Makarios proposed thirteen amendments to the constitution, which would have had the effect of resolving most of the issues in the Greek Cypriot favour. Under the proposals, the President and Vice-President would lose their veto, the separate municipalities as sought after by the Turkish Cypriots would be abandoned, the need for separate majorities by both communities in passing legislation would be discarded and the civil service contribution would be set at actual population ratios (82:18) instead of the slightly higher figure for Turkish Cypriots.
The intention behind the amendments has long been called into question. The Akritas plan, written in the height of the constitutional dispute by the Greek Cypriot interior minister Polycarpos Georkadjis, called for the removal of undesirable elements of the constitution so as to allow power-sharing to work. The plan envisaged a swift retaliatory attack on Turkish Cypriot strongholds should Turkish Cypriots resort to violence to resist the measures, stating "In the event of a planned or staged Turkish attack, it is imperative to overcome it by force in the shortest possible time, because if we succeed in gaining command of the situation (in one or two days), no outside, intervention would be either justified or possible." Whether Makarios's proposals were part of the Akritas plan is unclear, however it remains that sentiment towards enosis had not completely disappeared with independence. Makarios described independence as "a step on the road to enosis".[31] Preparations for conflict were not entirely absent from Turkish Cypriots either, with right wing elements still believing taksim (partition) the best safeguard against enosis.
Greek Cypriots however believe the amendments were a necessity stemming from a perceived attempt by Turkish Cypriots to frustrate the working of government. Turkish Cypriots saw it as a means to reduce their status within the state from one of co-founder to that of minority, seeing it as a first step towards enosis. The security situation deteriorated rapidly.
Main articles: Bloody Christmas (1963) and Battle of Tillyria
An armed conflict was triggered after December 21, 1963, a period remembered by Turkish Cypriots as Bloody Christmas, when a Greek Cypriot policemen that had been called to help deal with a taxi driver refusing officers already on the scene access to check the identification documents of his customers, took out his gun upon arrival and shot and killed the taxi driver and his partner. Eric Solsten summarised the events as follows: "a Greek Cypriot police patrol, ostensibly checking identification documents, stopped a Turkish Cypriot couple on the edge of the Turkish quarter. A hostile crowd gathered, shots were fired, and two Turkish Cypriots were killed."
In the morning after the shooting, crowds gathered in protest in Northern Nicosia, likely encouraged by the TMT, without incident. On the evening of the 22nd, gunfire broke out, communication lines to the Turkish neighbourhoods were cut, and the Greek Cypriot police occupied the nearby airport. On the 23rd, a ceasefire was negotiated, but did not hold. Fighting, including automatic weapons fire, between Greek and Turkish Cypriots and militias increased in Nicosia and Larnaca. A force of Greek Cypriot irregulars led by Nikos Sampson entered the Nicosia suburb of Omorphita and engaged in heavy firing on armed, as well as by some accounts unarmed, Turkish Cypriots. The Omorphita clash has been described by Turkish Cypriots as a massacre, while this view has generally not been acknowledged by Greek Cypriots.
Further ceasefires were arranged between the two sides, but also failed. By Christmas Eve, the 24th, Britain, Greece, and Turkey had joined talks, with all sides calling for a truce. On Christmas day, Turkish fighter jets overflew Nicosia in a show of support. Finally it was agreed to allow a force of 2,700 British soldiers to help enforce a ceasefire. In the next days, a "buffer zone" was created in Nicosia, and a British officer marked a line on a map with green ink, separating the two sides of the city, which was the beginning of the "Green Line". Fighting continued across the island for the next several weeks.
In total 364 Turkish Cypriots and 174 Greek Cypriots were killed during the violence. 25,000 Turkish Cypriots from 103-109 villages fled and were displaced into enclaves and thousands of Turkish Cypriot houses were ransacked or completely destroyed.
Contemporary newspapers also reported on the forceful exodus of the Turkish Cypriots from their homes. According to The Times in 1964, threats, shootings and attempts of arson were committed against the Turkish Cypriots to force them out of their homes. The Daily Express wrote that "25,000 Turks have already been forced to leave their homes". The Guardian reported a massacre of Turks at Limassol on 16 February 1964.
Turkey had by now readied its fleet and its fighter jets appeared over Nicosia. Turkey was dissuaded from direct involvement by the creation of a United Nations Peacekeeping Force in Cyprus (UNFICYP) in 1964. Despite the negotiated ceasefire in Nicosia, attacks on the Turkish Cypriot persisted, particularly in Limassol. Concerned about the possibility of a Turkish invasion, Makarios undertook the creation of a Greek Cypriot conscript-based army called the "National Guard". A general from Greece took charge of the army, whilst a further 20,000 well-equipped officers and men were smuggled from Greece into Cyprus. Turkey threatened to intervene once more, but was prevented by a strongly worded letter from the American President Lyndon B. Johnson, anxious to avoid a conflict between NATO allies Greece and Turkey at the height of the Cold War.
Turkish Cypriots had by now established an important bridgehead at Kokkina, provided with arms, volunteers and materials from Turkey and abroad. Seeing this incursion of foreign weapons and troops as a major threat, the Cypriot government invited George Grivas to return from Greece as commander of the Greek troops on the island and launch a major attack on the bridgehead. Turkey retaliated by dispatching its fighter jets to bomb Greek positions, causing Makarios to threaten an attack on every Turkish Cypriot village on the island if the bombings did not cease. The conflict had now drawn in Greece and Turkey, with both countries amassing troops on their Thracian borders. Efforts at mediation by Dean Acheson, a former U.S. Secretary of State, and UN-appointed mediator Galo Plaza had failed, all the while the division of the two communities becoming more apparent. Greek Cypriot forces were estimated at some 30,000, including the National Guard and the large contingent from Greece. Defending the Turkish Cypriot enclaves was a force of approximately 5,000 irregulars, led by a Turkish colonel, but lacking the equipment and organisation of the Greek forces.
The Secretary-General of the United Nations in 1964, U Thant, reported the damage during the conflicts:
UNFICYP carried out a detailed survey of all damage to properties throughout the island during the disturbances; it shows that in 109 villages, most of them Turkish-Cypriot or mixed villages, 527 houses have been destroyed while 2,000 others have suffered damage from looting.
The situation worsened in 1967, when a military junta overthrew the democratically elected government of Greece, and began applying pressure on Makarios to achieve enosis. Makarios, not wishing to become part of a military dictatorship or trigger a Turkish invasion, began to distance himself from the goal of enosis. This caused tensions with the junta in Greece as well as George Grivas in Cyprus. Grivas's control over the National Guard and Greek contingent was seen as a threat to Makarios's position, who now feared a possible coup.[citation needed] The National Guard and Cyprus Police began patrolling the Turkish Cypriot enclaves of Ayios Theodoros and Kophinou, and on November 15 engaged in heavy fighting with the Turkish Cypriots.
By the time of his withdrawal 26 Turkish Cypriots had been killed. Turkey replied with an ultimatum demanding that Grivas be removed from the island, that the troops smuggled from Greece in excess of the limits of the Treaty of Alliance be removed, and that the economic blockades on the Turkish Cypriot enclaves be lifted. Grivas was recalled by the Athens Junta and the 12,000 Greek troops were withdrawn. Makarios now attempted to consolidate his position by reducing the number of National Guard troops, and by creating a paramilitary force loyal to Cypriot independence. In 1968, acknowledging that enosis was now all but impossible, Makarios stated, "A solution by necessity must be sought within the limits of what is feasible which does not always coincide with the limits of what is desirable."
After 1967 tensions between the Greek and Turkish Cypriots subsided. Instead, the main source of tension on the island came from factions within the Greek Cypriot community. Although Makarios had effectively abandoned enosis in favour of an 'attainable solution', many others continued to believe that the only legitimate political aspiration for Greek Cypriots was union with Greece.
On his arrival, Grivas began by establishing a nationalist paramilitary group known as the National Organization of Cypriot Fighters (Ethniki Organosis Kyprion Agoniston B or EOKA-B), drawing comparisons with the EOKA struggle for enosis under the British colonial administration of the 1950s.
The military junta in Athens saw Makarios as an obstacle. Makarios's failure to disband the National Guard, whose officer class was dominated by mainland Greeks, had meant the junta had practical control over the Cypriot military establishment, leaving Makarios isolated and a vulnerable target.
During the first Turkish invasion, Turkish troops invaded Cyprus territory on 20 July 1974, invoking its rights under the Treaty of Guarantee. This expansion of Turkish-occupied zone violated International Law as well as the Charter of the United Nations. Turkish troops managed to capture 3% of the island which was accompanied by the burning of the Turkish Cypriot quarter, as well as the raping and killing of women and children. A temporary cease-fire followed which was mitigated by the UN Security Council. Subsequently, the Greek military Junta collapsed on July 23, 1974, and peace talks commenced in which a democratic government was installed. The Resolution 353 was broken after Turkey attacked a second time and managed to get a hold of 37% of Cyprus territory. The Island of Cyprus was appointed a Buffer Zone by the United Nations, which divided the island into two zones through the 'Green Line' and put an end to the Turkish invasion. Although Turkey announced that the occupied areas of Cyprus to be called the Federated Turkish State in 1975, it is not legitimised on a worldwide political scale. The United Nations called for the international recognition of independence for the Republic of Cyprus in the Security Council Resolution 367.
In the years after the Turkish invasion of northern Cyprus one can observe a history of failed talks between the two parties. The 1983 declaration of the independent Turkish Republic of Cyprus resulted in a rise of inter-communal tensions and made it increasingly hard to find mutual understanding. With Cyprus' interest of a possible EU membership and a new UN Secretary-General Kofi Annan in 1997 new hopes arose for a fresh start. International involvement from sides of the US and UK, wanting a solution to the Cyprus dispute prior to the EU accession led to political pressures for new talks. The believe that an accession without a solution would threaten Greek-Turkish relations and acknowledge the partition of the island would direct the coming negotiations.
Over the course of two years a concrete plan, the Annan plan was formulated. In 2004 the fifth version agreed upon from both sides and with the endorsement of Turkey, US, UK and EU then was presented to the public and was given a referendum in both Cypriot communities to assure the legitimisation of the resolution. The Turkish Cypriots voted with 65% for the plan, however the Greek Cypriots voted with a 76% majority against. The Annan plan contained multiple important topics. Firstly it established a confederation of two separate states called the United Cyprus Republic. Both communities would have autonomous states combined under one unified government. The members of parliament would be chosen according to the percentage in population numbers to ensure a just involvement from both communities. The paper proposed a demilitarisation of the island over the next years. Furthermore it agreed upon a number of 45000 Turkish settlers that could remain on the island. These settlers became a very important issue concerning peace talks. Originally the Turkish government encouraged Turks to settle in Cyprus providing transfer and property, to establish a counterpart to the Greek Cypriot population due to their 1 to 5 minority. With the economic situation many Turkish-Cypriot decided to leave the island, however their departure is made up by incoming Turkish settlers leaving the population ratio between Turkish Cypriots and Greek Cypriots stable. However all these points where criticised and as seen in the vote rejected mainly by the Greek Cypriots. These name the dissolution of the „Republic of Cyprus", economic consequences of a reunion and the remaining Turkish settlers as reason. Many claim that the plan was indeed drawing more from Turkish-Cypriot demands then Greek-Cypriot interests. Taking in consideration that the US wanted to keep Turkey as a strategic partner in future Middle Eastern conflicts.
A week after the failed referendum the Republic of Cyprus joined the EU. In multiple instances the EU tried to promote trade with Northern Cyprus but without internationally recognised ports this spiked a grand debate. Both side endure their intention of negotiations, however without the prospect of any new compromises or agreements the UN is unwilling to start the process again. Since 2004 negotiations took place in numbers but without any results, both sides are strongly holding on to their position without an agreeable solution in sight that would suit both parties.

My first experience about YNP
We entered Yellowstone NP through the eastern entrance using U.S. Route 14. It had been a moderate snow fall in the end of the first week of October, 2017. From few kilometers before reaching Yellowstone Lake, remnants of devastating wild fire were being evident. It was a shocking sight for me at the beginning and could not perceive how fire had devastated hundreds of acres of alpine forests in the valleys and atop the hills. But when I had a closer look to the floor of the forests, I was amazed by the facts how nature maintains its ecological balance! Numerous tiny siblings are growing besides the burnt and decaying logs. The future forests of the park are coming alive.
The park seemed to me the world’s finest natural laboratory and archive to study and understand all the faculties of human intellect.
The qualities of the photographs are not satisfactory, because they were taken so fast through the glass windows of our running bus. But I didn’t want to miss such life time opportunities. The overall beauties were essentially more important than technicalities, as I always believe.
Our luck didn’t favor anyway in this park trip, when our tour guide had declared a forecast for heavy snowfall next day since morning. He therefore decided to visit as many spots as possible in a single day, and not to wait for day-2. I hurried through the trails taking as many snaps as possible.
The next day heavy snowfall started since 9 am, and our guide cancelled the day-2 trip. Thanks God…we covered somehow all the spots on the first day.
I hope, you may like my Yellowstone series…
A quick overview of YNP
Yellowstone National Park is an American national park located in Wyoming, Montana, and Idaho. Approximately 96 percent of the land area of Yellowstone National Park is located within the state of Wyoming. The Park spans an area of 8,983 km2 comprising lakes, canyons, rivers and mountain ranges. The park is known for its wildlife and its many geothermal features. It has many types of ecosystems, but the subalpine forest is the most abundant. It is part of the South Central Rockies forests eco-region.
It was established by the U.S. Congress and signed into law by President Ulysses S. Grant on March 1, 1872. Yellowstone was the first national park in the U.S. and is also widely held to be the first national park in the world. Native Americans have lived in the Yellowstone region for at least 11,000 years. Aside from visits by mountain -men during the early to mid-19th century, organized exploration did not begin until the late 1860s.
The park contains the headwaters of the Yellowstone River, from which it takes its historical name. Although it is commonly believed that the river was named for the yellow rocks seen in the ‘Grand Canyon of the Yellowstone’, the Native American name source is unclear.
Yellowstone Lake is one of the largest high-elevation lakes in North America and is centered over the Yellowstone Caldera, the largest supervolcano on the continent. The caldera is considered as an active volcano. It has erupted with tremendous force several times in the last two million year. The Yellowstone Caldera is the largest volcanic system in North America. It has been termed a "supervolcano" because the caldera was formed by exceptionally large explosive eruptions. The magma chamber that lies under Yellowstone is estimated to be a single connected chamber, about 60 km long, 29 km wide, and 5 to 12 km deep. Yellowstone Lake is up to 400 feet deep and has 180 km of shoreline.The lake is at an elevation of 7,733 feet above sea levels. Half of the world's geysers and hydrothermal features are there in Yellowstone, fueled by this ongoing volcanism. Lava and rocks from volcanic eruptions cover most of the land area of Yellowstone. The park is the centerpiece of the Greater Yellowstone Ecosystem, the largest remaining nearly-intact ecosystem in the Earth's northern temperate zone. In 1978, Yellowstone was named a UNESCO World Heritage Site.
In May 2001, the U.S. Geological Survey, Yellowstone National Park, and the University of Utah created the Yellowstone Volcano Observatory (YVO), a partnership for long-term monitoring of the geological processes of the Yellowstone Plateau volcanic field, for disseminating information concerning the potential hazards of this geologically active region.
Hundreds of species of mammals, birds, fish, and reptiles have been documented, including several that are either endangered or threatened. The vast forests and grasslands also include unique species of plants. Yellowstone Park is the largest and most famous mega fauna location in the contiguous United States. Grizzly bears, wolves, and free-ranging herds of bison and elk live in this park. The Yellowstone Park bison herd is the oldest and largest public bison herd in the United States.
Forest fires occur in the park each year. In the largest forest fires of 1988, nearly one third of the park was burnt.
Yellowstone has numerous recreational opportunities, including hiking, camping, boating, fishing and sightseeing. Paved roads provide close access to the major geothermal areas as well as some of the lakes and waterfalls. During the winter, visitors often access the park by way of guided tours that use either snow coaches or snowmobiles.
Fire in Yellowstone NP:
Causes of wildfire in Yellowstone NP
Wildfire has had a role in the dynamics of Yellowstone’s ecosystems for thousands of years. Although many fires were caused by human activities, most ignitions were natural. The term "natural ignition" usually refers to a lightning strike. Afternoon thunderstorms occur frequently in the northern Rocky Mountains but release little precipitation, a condition known as ‘dry lightning’. In a typical season there are thousands of lightning strikes in Yellowstone. Lightning strikes are powerful enough to rip strips of bark off of a tree in a shower of sparks and blow the pieces up to 100 feet away. However, most lightning strikes do not result in a wildfire because fuels are not in a combustible state.
The great fire incidence of 1988
The Yellowstone fires of 1988 collectively formed the largest wildfire in the recorded history of Yellowstone National Park in the United States. Starting as many smaller individual fires, the flames quickly spread out of control due to drought conditions and increasing winds, combining into one large conflagration which burned for several months. The fires almost destroyed two major visitor destinations and, on September 8, 1988, the entire park closed to all non-emergency personnel for the first time in its history. Only the arrival of cool and moist weather in the late autumn brought the fires to an end. A total of 793,880 acres, or 36 percent of the park was affected by the wildfires.
Fire incidence, 2016
As of September 21, 2016, 22 fires (human and lightning-caused) have burned more than 62,000 acres in Yellowstone National Park, making it the highest number of acres burned since the historic 1988 fire.
Heritage and Research Center
The Heritage and Research Center is located at Gardiner, Montana, near the north entrance to the park. The center is home to the Yellowstone National Park's museum collection, archives, research library, historian, archeology lab, and herbarium. The Yellowstone National Park Archives maintain collections of historical records of Yellowstone and the National Park Service. The collection includes the administrative records of Yellowstone, as well as resource management records, records from major projects, and donated manuscripts and personal papers. The archives are affiliated with the National Archives and Records Administration.
Geothermal features of Yellowstone NP- A brief note:
There are four geothermal features found in the park – Hot springs, Geysers, Fumaroles , and Mud volcanoes/pots.
What is a Hot spring?
Hot spring, also called thermal spring, spring with water at temperatures substantially higher than the air temperature of the surrounding region. Most hot springs discharge groundwater that is heated by shallow intrusions of magma (molten rock) in volcanic areas.
Some thermal springs, however, are not related to volcanic activity. In general, the temperature of rocks within the earth increases with depth. The rate of temperature increase with depth is known as the geothermal gradient. In such cases, the water is heated by convective circulation: groundwater percolating downward reaches depths of a kilometre or more where the temperature of rocks is high because of the normal temperature gradient of the Earth’s crust—about 30 °C / kilometer in the first 10 km. The water from hot springs in non-volcanic areas is heated in this manner.
But in active volcanic zones such as Yellowstone National Park, water may be heated by coming into contact with magma (molten rock). The high temperature gradient near magma may cause water to be heated enough that it boils or becomes superheated. If the water becomes so hot that it builds steam pressure and erupts in a jet above the surface of the Earth, it is called a geyser.
[ Warm springs are sometimes the result of hot and cold springs mixing. They may occur within a volcanic area or outside of one. One example of a non-volcanic warm spring is Warm Springs, Georgia (frequented for its therapeutic effects by paraplegic U.S. President Franklin D. Roosevelt, who built the Little White House there) ].
List of hot springs:
[ en.wikipedia.org/wiki/List_of_hot_springs ]
The science of colors of a hot spring:
[ ttps://www.britannica.com/science/hot-spring]
Many of the colours in hot springs are caused by thermophilic (heat-loving) microorganisms, which include certain types of bacteria, such as cyanobacteria, and species of archaea and algae. Many thermophilic organisms grow in huge colonies called mats that form the colourful scums and slimes on the sides of hot springs. The microorganisms that grow in hot springs derive their energy from various chemicals and metals; potential energy sources include molecular hydrogen, dissolved sulfides, methane, iron, ammonia, and arsenic. In addition to geochemistry, the temperature and pH of hot springs play a central role in determining which organisms inhabit them.
Examples of thermophilic microorganisms found in hot springs include bacteria in the genera Sulfolobus, which can grow at temperatures of up to 90 °C (194 °F), Hydrogenobacter, which grow optimally at temperatures of 85 °C (185 °F), and Thermocrinis, which grow optimally at temperatures of 80 °C (176 °F). Thermophilic algae in hot springs are most abundant at temperatures of 55 °C (131 °F) or below.
What is a Geyser?
A geyser is formed when water collecting below the surface is heated by a magma source. When the water boils, it rises to the surface. If the water has an unobstructed path, it will pool on the surface in the form of a steaming hot springs. If the passage of the water is imposed upon, the pressure will increase. When the pressure becomes too great, the water converts into to steam. Steam takes up 1,500 times the volume of water, and at this point, the pressure becomes so intense that the steam and surrounding water droplets shoot out of the ground in geyser form, erupting until the pressure has abated and the process starts all over again.
What is a fumarole?
It’s a vent in the Earth’s surface from which steam and volcanic gases are emitted. The major source of the water vapour emitted by fumaroles is groundwater heated by bodies of magma lying relatively close to the surface. Carbon dioxide, sulfur dioxide, and hydrogen sulfide are usually emitted directly from the magma. Fumaroles are often present on active volcanoes during periods of relative quiet between eruptions.
Fumaroles are closely related to hot springs and geysers. In areas where the water table rises near the surface, fumaroles can become hot springs. A fumarole rich in sulfur gases is called a solfatara; a fumarole rich in carbon dioxide is called a mofette. If the hot water of a spring only reaches the surface in the form of steam, it is called a fumarole. [ www.britannica.com/science/fumarole ]
What is a mud volcano/ mud pot/ paint pot?-
Usually mud volcanoes are created by hot-spring activity where large amounts of gas and small amounts of water react chemically with the surrounding rocks and form a boiling mud.
Geo-chemistry of mud volcano: Hydrogen sulfide gas rising from magma chamber, as in Yellowstone’s, causes the rotten-egg smell. Microorganisms, or thermophiles, use this gas as a source of energy, and then help turn the gas into sulfuric acid. The acid then breaks down the rocks and soil into mud. Many of the colors seen are vast communities of thermophiles, but some of the yellow is pure sulfur. When iron mixes with sulfur to form iron sulfide, gray and black swirls sometimes appear in the mud (From description of the display board in the park).
If the water of a hot spring is mixed with mud and clay, it is called a mud pot. Variations are the porridge pot (a basin of boiling mud that erodes chunks of the surrounding rock) and the paint pot (a basin of boiling mud that is tinted yellow, green, or blue by minerals from the surrounding rocks).
There are other mud volcanoes, entirely of a nonigneous origin, occur only in oil-field regions that are relatively young and have soft, unconsolidated formations.
