Okay, so this is actually from a year ago. At the time, it suffered from being part of the same shoot as "Iris." Now I'm feeling pretty guilty for having ignored it, and I kinda can't wait for summer when I can afford to have it printed on a big piece of metal by these guys: www.imagewizards.net/
Oh. That's right, some of you may not already know of my obsession and won't know what this is. It's a macro of a section of surface ice from Lake Charlevoix, turned upright and backlit by the setting sun. Cool, right? There are whole galaxies in there. I think it's time for a Hubble Microscope.
The Grey (or Gray) squirrel, you either love 'em or you hate 'em. Cute and fluffy little funsters or destructive critters who ruin trees, kill bird chicks and trees and damage our homes... oh and it's their fault we lost our native Red squirrels as well!
OK
I get it and I see both sides of the story of course. For my part, I am a nature, wildlife and landscape photographer who prefers the company of animals and natural beauty to fellow humans who are systematically plundering Mother Earth's resources and killing off her beautiful creatures at an alarming rate! I believe there is a natural order of things, creatures kill other creatures to survive, they adapt to situations and when mankind encroaches on their territory to make a fast buck, those animals sometimes adapt to survive and the order changes.
That is the balance of nature which is ever changing and affected by us..... the dumbest of the great apes. Some species are driven out by others, some may be destined to become extinct, the fittest will survive, and sometime a species will need intervention and help from mankind in order to survive... usually as a direct consequence of mankind's own actions in destroying the animal kingdom's natural habitat of course.
I adore these little fellas and at almost sixty years old, I never grew up knowing red squirrels at all. I've seen reds in Scotland and black squirrels in Stanley Park on Vancouver Island in British Columbia, Canada, but in my beloved home country of England I have always known and loved the cute little Greys. They visit my garden and give me hours, days, weeks of happiness and wonderful photographic opportunities, and I see them in Parks and forests all around me, so it's time to offer up an insight into the Grey squirrel, much loved, much hated... a sort of Marmite rodent if you will.
WHAT EXACTLY IS A SQUIRREL?
The word 'Squirrel', was first recorded in 1327 and hails from the Anglo-Norman word 'Esquirel', from old French 'Escurel', which was a reflex for the Latin word 'Sciurus'.The Eastern gray squirrel (Sciurus carolinensis) is also known as the Eastern Grey squirrel or simply grey squirrel depending on the region of the world it is found. It is a tree squirrel, of the squirrel family Sciuridae including over one hundred arboreal species native to all continents of the world other than Antarctica and Oceania. Tree squirrels live mostly in trees, apart from the flying squirrel. The best known genus is Sciurus, containing most of the bushy tailed squirrels which are found in Europe, North America, temperate Asia as well as central and south America.
The scientific classification for the Eastern Grey is:
KINGDOM: ANIMALIA PHYLUM: CHORDATA CLASS: MAMMALIA ORDER: RODENTIA FAMILY: SCIURIDAE GENUS: SCIURUS SUBGENUS: SCIURUS SPECIES: SCIURUS CAROLINENSIS
They were first noted by German naturalist, botanist, entomologist, herpetologist, and malacologist - Johann Friedrich Gmelin in 1788.
A mammal and rodent, predominantly herbivorous they are none the less an omnivore with a life span of between two and ten years. They can grow to 70cm in length and weigh up to 8kg. There are more than two hundred and sixty species of worldwide squirrel, the smallest being the African pygmy squirrel at just 10cm in length, whereas the Indian giant squirrel is three feet long! The oldest fossil of a squirrel, Hesperopetes, dates back to the late Eocene epoch period Chadronian period of 40-35 million years ago. The tree squirrels rotate their ankles by 180 degrees, so that the hind paws pointy backwards gripping tree bark which enables them to descend a tree headfirst.
Originally native to Eastern and Midwestern United States of America, they were first introduced into the United Kingdom in 1876 in Henbury Park, Macclesfield in Cheshire when Victorian banker Thomas V. Brocklehurst released a pair of Greys that he brought back from a business trip to America after their attraction as pets had waned. Victorians had a penchant for collecting exotic animals and birds of the world, but trends came and went and subsequently animals were simply discarded into the wilderness. There are early records of greys released near Denbighshire in north Wales from private collections. Later introduced to several regions in the UK, they quickly settled and spread, colonizing an area of three hundred miles in a quarter of a century between Argyll and Stirlingshire in Scotland.
Introductions of the Greys between 1902 and 1929 (the year of the last recorded introduction), included: Regent’s Park in London, Berkshire, Northamptonshire, Oxfordshire, Oxfordshire, Devon, Warwickshire, Nottinghamshire, Suffolk and Hampshire. Grey Squirrels spread into Gloucestershire and eastern Wiltshire with animals coming directly from the United States or from Woburn. One hundred greys were released in Richmond Park in Surrey in 1902, Ninety one into Regent’s Park between 1905 and 1907 and a further ten New Jersey imported greys were introduced into Woburn Park in Bedfordshire.
Predators include hawks, weasels, raccoons, bobcats, foxes, domestic and feral cats, snakes, owls, and dogs, African harrier-hawks in Africa and... oh yes, Mankind pretty much everywhere who despise, mistreat, cull or eat it .
FACTS, MYTHS AND THAT POXY PARAPOX!
The massive decline in native red squirrels blamed upon the spread of the invasive greys has always been perhaps a little harsh as reds were already in a steep decline due to loss of habitat and disease and thus the greys simply took over the areas where the reds were dwindling. It's also a fact that reds were also seen as a plague, branded as pests who killed birds and damaged trees and the culling of reds almost brought them to the brink of extinction. Licenses to kill reds could still be obtained up until the seventies!
Reds suffered at the hands of mankind thanks to a combination of agricultural deforestation also linked with war and fuel needs which caused extinction in Southern Scotland and Ireland by the early eighteenth century, way before greys had been introduced. Harsh winters killed off the less hardy red population in the early nineteenth and twentieth centuries.
Greys are more adept at finding food and adapting to locations and environments, but also carry the squirrel poxvirus (SQPV) which although not particularly harmful to them, is a serious infection for the reds.
Parapox in red squirrels causes swollen lesions around the mouth, eyes, ears and nose also the front paws and sometimes genitals and skin ulcers and kills a red within fifteen days. There is no definitive correlation between the spread of the virus and the spread of the Greys, it actually arrived in several areas before the greys began to colonize there. An epidemic virus was observed in Red squirrels from at least 1900 with isolation attempts failing, and the first case of Parapox in the UK was in 1980 in the county of Norfolk. Greys cannot transmit the virus to reds via saliva or faeces, but reds can between each other from bodily secretions and at animal feeders in gardens. The transmission from greys to reds is though to come from parasites. Eight to ten per cent of reds survive the virus, and there is some evidence that reds are slowly building an evolved resistance.
Greys are seen as pests to forest land, stripping bark from trees during May and June, and are also capable of destroying household bins, water pipes, causing roof damage not to mention taking eggs and killing young chicks of ground nesting and songbird populations. They also take from bird feeders and there is a whole industry for creating squirrel proof feeders these days.
THE CULLING OF GREY SQUIRRELS
Grey squirrels have limited legal protection and can be legally controlled all year round by a variety of methods including shooting and trapping. Methods of trapping and killing include Drey poking and shooting, Tunnel trapping using spring traps set in accordance with BASC’s trapping pest mammals code of practice. They can also be shot using a shotgun or powerful air rifle or up until September 30th 2014 poisoned by Warfarin (Now outlawed).
Whilst professional trapping and extermination is hopefully done as humanely as possible, there have been cases, many of them where cost savings have been gained by battering the squirrels to death! Grey squirrels are trapped in ghastly metal contraptions for hours and hours, wearing themselves out frantically trying to escape by gnawing at the metals bars. They bite the floor and scratch at them with their claws and do not get a moments peace or rest through absolute fear. Once the traps are retrieved, each squirrel, terrified will be thrown into a sack and smacked on the head countless times with a blunt instrument. When a mother is slaughtered, her babies who are totally dependent on her, will die a slow death of thirst and starvation.
There is an argument for the control of Greys on many grounds but also a counter argument that Culling does not work, and has not on countless times where, once a population of greys have been culled, the nearest group will move back in and claim the land. The university of Bristol concluded that there was little evidence that culling greys to save red squirrels was effective, and that perhaps finding a way of boosting red squirrel immunity to the poxvirus or planting areas of yew trees where reds are known to thrive and spending money on research into positive moves might be a better option.
In Ireland, the re-introduction of the Pine marten, a species made extinct originally by the very same land owners who also wish to do the same to the grey squirrel, has seen the rapid demise of the grey and the re-introction of the native reds. Red squirrels are smaller and more nimble than their grey counterparts, and as such can get to the very ends of tree branches where neither the pine martins, nor more importantly the heavier greys can, thus surviving and thriving. As a result in Ireland, the grey squirrel population has crashed in approximately 9,000 km2 of its former range and the reds has become common once more after a thirty year absence... oh and Pine Martens are protected again!
In Scotland, Pine Martens exist in areas where Red squirrels thrive, and greys do not. So perhaps there is a lesson here, as in England where there are no pine martens, the greys are prolific breeders. So there is an argument against the barbarity of shooting and poisoning greys, and if, as so many believe, the greys MUST be controlled, how about a more humane and natural method that nature intended.. with re-introduction of predators. Just a thought!
So a few facts and figures on the greys and to wrap up, from a purely personal perspective I love these little guys, as I do almost every creature in nature other than those eight legged beasties that shall not be named and for which I have a deep and powerful phobia that borders on paranoia!
I could no more harm an animal deliberately than eat a McDonald's McRib (Once saw how they are made and let me just say... eeeuuuuuwwwww!!).
They are small, cute, cuddly, furry, they photograph beautifully, have great personality and make me smile. They trust me enough to take food from my hand in parks, and I can't bare the though of ugly, hairy land owners sticking a shotgun in their face and blowing them away! I appreciate they can be a pest, a problem, a menace, that their PR managers might have a bit of a problem winning you over when they flay small chicks alive on your lawn or decimate the songbird population by stealing their eggs.... and perhaps there is a need to keep the population under control and try and re-establish the red population.....
Yep I get that....
I just hope we can solve the problem more humanely to create a peaceful coexistence of the reds and greys in different areas. A man can dream can't he.

Not really, this is a fence along the trail that I took this morning on our walk. But before our walk I was sitting at the computer and felt my chair bumping around. Sure enough, a 4.5 earthquake, epicenter 78 miles from here and felt throughout southern California. Los Angeles, Riverside, San Diego counties and our own Orange County got shaken up for only seconds this morning.
It was just a typical event occurring deep in the San Andreas Fault, always creating little quakes but today's was bigger. Luckily no damage reported anywhere. We don't mind our quakes unless they do damage. :D
I cuss.
I swear.
I have a dirty mouth.
But let's pretend it's not my fault. It's just my fucking Tourette's.
Available soon at my etsy shop.
Sometimes it is a simple fix. A wire pulled from the connector was the source of the problem. I had already removed the speed sender from the gearbox and checked the plastic drive gear was engaged with the worm gear on the output shaft which it was. I then tested both the sender units. I initially had some erratic reading then dead on both senders. I removed the cover from the back of the multi plug and found this. I have carried out a repair but I will need to lengthen the loom to the gear box as it is just a bit too short.
The geothermal areas of Yellowstone include several geyser basins in Yellowstone National Park as well as other geothermal features such as hot springs, mud pots, and fumaroles. The number of thermal features in Yellowstone is estimated at 10,000. A study that was completed in 2011 found that a total of 1,283 geysers have erupted in Yellowstone, 465 of which are active during an average year. These are distributed among nine geyser basins, with a few geysers found in smaller thermal areas throughout the Park. The number of geysers in each geyser basin are as follows: Upper Geyser Basin (410), Midway Geyser Basin (59), Lower Geyser Basin (283), Norris Geyser Basin (193), West Thumb Geyser Basin (84), Gibbon Geyser Basin (24), Lone Star Geyser Basin (21), Shoshone Geyser Basin (107), Heart Lake Geyser Basin (69), other areas (33). Although famous large geysers like Old Faithful are part of the total, most of Yellowstone's geysers are small, erupting to only a foot or two. The hydrothermal system that supplies the geysers with hot water sits within an ancient active caldera. Many of the thermal features in Yellowstone build up sinter, geyserite, or travertine deposits around and within them.
The various geyser basins are located where rainwater and snowmelt can percolate into the ground, get indirectly superheated by the underlying Yellowstone hotspot, and then erupt at the surface as geysers, hot springs, and fumaroles. Thus flat-bottomed valleys between ancient lava flows and glacial moraines are where most of the large geothermal areas are located. Smaller geothermal areas can be found where fault lines reach the surface, in places along the circular fracture zone around the caldera, and at the base of slopes that collect excess groundwater. Due to the Yellowstone Plateau's high elevation the average boiling temperature at Yellowstone's geyser basins is 199 °F (93 °C). When properly confined and close to the surface it can periodically release some of the built-up pressure in eruptions of hot water and steam that can reach up to 390 feet (120 m) into the air (see Steamboat Geyser, the world's tallest geyser). Water erupting from Yellowstone's geysers is superheated above that boiling point to an average of 204 °F (95.5 °C) as it leaves the vent. The water cools significantly while airborne and is no longer scalding hot by the time it strikes the ground, nearby boardwalks, or even spectators. Because of the high temperatures of the water in the features it is important that spectators remain on the boardwalks and designated trails. Several deaths have occurred in the park as a result of falls into hot springs.
Prehistoric Native American artifacts have been found at Mammoth Hot Springs and other geothermal areas in Yellowstone. Some accounts state that the early people used hot water from the geothermal features for bathing and cooking. In the 19th century Father Pierre-Jean De Smet reported that natives he interviewed thought that geyser eruptions were "the result of combat between the infernal spirits". The Lewis and Clark Expedition traveled north of the Yellowstone area in 1806. Local natives that they came upon seldom dared to enter what we now know is the caldera because of frequent loud noises that sounded like thunder and the belief that the spirits that possessed the area did not like human intrusion into their realm. The first white man known to travel into the caldera and see the geothermal features was John Colter, who had left the Lewis and Clark Expedition. He described what he saw as "hot spring brimstone". Beaver trapper Joseph Meek recounted in 1830 that the steam rising from the various geyser basins reminded him of smoke coming from industrial smokestacks on a cold winter morning in Pittsburgh, Pennsylvania. In the 1850s famed trapper Jim Bridger called it "the place where Hell bubbled up".
The heat that drives geothermal activity in the Yellowstone area comes from brine (salty water) that is 1.5–3 miles (7,900–15,800 ft; 2,400–4,800 m) below the surface. This is actually below the solid volcanic rock and sediment that extends to a depth of 3,000 to 6,000 feet (900 to 1,800 m) and is inside the hot but mostly solid part of the pluton that contains Yellowstone's magma chamber. At that depth the brine is superheated to temperatures that exceed 400 °F (204 °C) but is able to remain a liquid because it is under great pressure (like a huge pressure cooker).
Convection of the churning brine and conduction from surrounding rock transfers heat to an overlaying layer of fresh groundwater. Movement of the two liquids is facilitated by the highly fractured and porous nature of the rocks under the Yellowstone Plateau. Some silica is dissolved from the fractured rhyolite into the hot water as it travels through the fractured rock. Part of this hard mineral is later redeposited on the walls of the cracks and fissures to make a nearly pressure-tight system. Silica precipitates at the surface to form either geyserite or sinter, creating the massive geyser cones, the scalloped edges of hot springs, and the seemingly barren landscape of geyser basins.
There are at least five types of geothermal features found at Yellowstone:
Fumaroles: Fumaroles, or steam vents, are the hottest hydrothermal features in the park. They have so little water that it all flashes into steam before reaching the surface. At places like Roaring Mountain, the result is loud hissing of steam and gases.
Geysers: Geysers such as Old Faithful are a type of geothermal feature that periodically erupt scalding hot water. Increased pressure exerted by the enormous weight of the overlying rock and water prevents deeper water from boiling. As the hot water rises it is under less pressure and steam bubbles form. They, in turn, expand on their ascent until the bubbles are too big and numerous to pass freely through constrictions. At a critical point the confined bubbles actually lift the water above, causing the geyser to splash or overflow. This decreases the pressure of the system and violent boiling results. Large quantities of water flash into tremendous amounts of steam that force a jet of water out of the vent: an eruption begins. Water (and heat) is expelled faster than the geyser's recharge rate, gradually decreasing the system's pressure and eventually ending the eruption.
Hot springs: Hot springs such as Grand Prismatic Spring are the most common hydrothermal features in the park. Their plumbing has no constrictions. Superheated water cools as it reaches the surface, sinks, and is replaced by hotter water from below. This circulation, called convection, prevents water from reaching the temperature needed to set off an eruption. Many hot springs give rise to streams of heated water.
Mudpots: Mudpots such as Fountain Paint Pots are acidic hot springs with a limited water supply. Some microorganisms use hydrogen sulfide (rotten egg smell), which rises from deep within the earth, as an energy source. They convert the gas into sulfuric acid, which breaks down rock into clay.
Travertine terraces: Travertine terraces, found at Mammoth Hot Springs, are formed from limestone (a rock type made of calcium carbonate). Thermal waters rise through the limestone, carrying high amounts of dissolved carbonate. Carbon dioxide is released at the surface and calcium carbonate deposited as travertine, the chalky white rock of the terraces. These features constantly and quickly change due to the rapid rate of deposition.
Geyser basins
The Norris Geyser Basin 44°43′43″N 110°42′16″W is the hottest geyser basin in the park and is located near the northwest edge of Yellowstone Caldera near Norris Junction and on the intersection of three major faults. The Norris-Mammoth Corridor is a fault that runs from Norris north through Mammoth to the Gardiner, Montana, area. The Hebgen Lake fault runs from northwest of West Yellowstone, Montana, to Norris. This fault experienced an earthquake in 1959 that measured 7.4 on the Richter scale (sources vary on exact magnitude between 7.1 and 7.8; see 1959 Hebgen Lake earthquake). Norris Geyser Basin is so hot and dynamic because these two faults intersect with the ring fracture zone that resulted from the creation of the Yellowstone Caldera of 640,000 years ago.
The Basin consists of three main areas: Porcelain Basin, Back Basin, and One Hundred Springs Plain. Unlike most of other geyser basins in the park, the waters from Norris are acidic rather than alkaline (for example, Echinus Geyser has a pH of ~3.5). The difference in pH allows for a different class of bacterial thermophiles to live at Norris, creating different color patterns in and around the Norris Basin waters.
The Ragged Hills that lie between Back Basin and One Hundred Springs Plain are thermally altered glacial kames. As glaciers receded the underlying thermal features began to express themselves once again, melting remnants of the ice and causing masses of debris to be dumped. These debris piles were then altered by steam and hot water flowing through them. Madison lies within the eroded stream channels cut through lava flows formed after the caldera eruption. The Gibbon Falls lies on the caldera boundary as does Virginia Cascades.

The tallest active geyser in the world, Steamboat Geyser,[11] is located in Norris Basin. Unlike the slightly smaller but much more famous Old Faithful Geyser located in Upper Geyser Basin, Steamboat has an erratic and lengthy timetable between major eruptions. During major eruptions, which may be separated by intervals of more than a year (the longest recorded span between major eruptions was 50 years), Steamboat erupts over 300 feet (90 m) into the air. Steamboat does not lie dormant between eruptions, instead displaying minor eruptions of approximately 40 feet (12 m).
Norris Geyser Basin periodically undergoes a large-scale, basin-wide thermal disturbance lasting a few weeks. Water levels fluctuate, and temperatures, pH, colors, and eruptive patterns change throughout the basin. During a disturbance in 1985, Porkchop Geyser continually jetted steam and water; in 1989, the same geyser apparently clogged with silica and blew up, throwing rocks more than 200 feet (61 m). In 2003 a park ranger observed it bubbling heavily, the first such activity seen since 1991. Activity increased dramatically in mid-2003. Because of high ground temperatures and new features beside the trail much of Back Basin was closed until October. In 2004 the boardwalk was routed around the dangerous area and now leads behind Porkchop Geyser.
North of Norris, Roaring Mountain is a large, acidic hydrothermal area (solfatara) with many fumaroles. In the late 19th and early 20th centuries, the number, size, and power of the fumaroles were much greater than today. The fumaroles are most easily seen in the cooler, low-light conditions of morning and evening.
The Gibbon Geyser Basin 44°41′58″N 110°44′34″W includes several thermal areas in the vicinity of the Gibbon River between Gibbon Falls and Norris. The most accessible feature in the basin is Beryl Spring, with a small boardwalk right along the Grand Loop Road. Artists' Paintpots is a small hydrothermal area south of Norris Junction that includes colorful hot springs and two large mudpots.
The Monument Geyser Basin 44°41′03″N 110°45′14″W has no active geysers, but its 'monuments' are siliceous sinter deposits similar to the siliceous spires discovered on the floor of Yellowstone Lake. Scientists hypothesize that this basin's structures formed from a hot water system in a glacially dammed lake during the waning stages of the Pinedale Glaciation. The basin is on a ridge reached by a very steep one-mile (1.6 km) trail south of Artists' Paint Pots. Other areas of thermal activity in Gibbon Geyser Basin lie off-trail.
South of Norris along the rim of the caldera is the Upper Geyser Basin 44°27′52″N 110°49′45″W, which has the highest concentration of geothermal features in the park. This complement of features includes the most famous geyser in the park, Old Faithful Geyser, as well as four other predictable large geysers. One of these large geysers in the area is Castle Geyser which is about 1,400 feet (430 m) northwest of Old Faithful. Castle Geyser has an interval of approximately 13 hours between major eruptions, but is unpredictable after minor eruptions. The other three predictable geysers are Grand Geyser, Daisy Geyser, and Riverside Geyser. Biscuit Basin and Black Sand Basin are also within the boundaries of Upper Geyser Basin.
The hills surrounding Old Faithful and the Upper Geyser Basin are reminders of Quaternary rhyolitic lava flows. These flows, occurring long after the catastrophic eruption of 640,000 years ago, flowed across the landscape like stiff mounds of bread dough due to their high silica content.
Evidence of glacial activity is common, and it is one of the keys that allows geysers to exist. Glacier till deposits underlie the geyser basins providing storage areas for the water used in eruptions. Many landforms, such as Porcupine Hills north of Fountain Flats, are made up of glacial gravel and are reminders that 70,000 to 14,000 years ago, this area was buried under ice.
Signs of the forces of erosion can be seen everywhere, from runoff channels carved across the sinter in the geyser basins to the drainage created by the Firehole River. Mountain building is evident on the drive south of Old Faithful, toward Craig Pass. Here the Rocky Mountains reach a height of 8,262 feet (2,518 m), dividing the country into two distinct watersheds.
Midway Geyser Basin 44°31′04″N 110°49′56″W is much smaller than the other basins found alongside the Firehole River. Despite its small size, it contains two large features, the 200-by-300-foot-wide (60 by 90 m) Excelsior Geyser which pours over 4,000 U.S. gallons (15,000 L; 3,300 imp gal) per minute into the Firehole River. The largest hot spring in Yellowstone, the 370-foot-wide (110 m) and 121-foot-deep (37 m) Grand Prismatic Spring is found here. Also in the basin is Turquoise Pool and Opal Pool.

Silex Spring at Fountain Paint Pot
Farther north is the Lower Geyser Basin 44°32′58″N 110°50′09″W, which is the largest geyser basin in area, covering approximately 11 square miles. Due to its large size, it has a much less concentrated set of geothermal features, including Fountain Paint Pots. Fountain Paint Pots are mud pots, that is, a hot spring that contains boiling mud instead of water. The mud is produced by a higher acidity in the water which enables the spring to dissolve surrounding minerals to create an opaque, usually grey, mud. Also there is Firehole Spring, Celestine Pool, Leather Pool, Red Spouter, Jelly spring, and a number of fumaroles.
Geysers in Lower Geyser Basin include Great Fountain Geyser, whose eruptions reach 100 to 200 feet (30–61 m) in the air, while waves of water cascade down its sinter terraces., the Fountain group of Geysers (Clepsydra Geyser which erupts nearly continuously to heights of 45 feet (14 m), Fountain Geyser, Jelly Geyser, Jet Geyser, Morning Geyser, and Spasm Geyser), the Pink Cone group of geysers (Dilemma Geyser, Labial Geyser, Narcissus Geyser, Pink Geyser, and Pink Cone Geyser), the White Dome group of geysers (Crack Geyser, Gemini Geyser, Pebble Geyser, Rejuvenated Geyser, and White Dome Geyser), as well as Sizzler Geyser.

The West Thumb Geyser Basin 44°25′07″N 110°34′23″W, including Potts Basin to the north, is the largest geyser basin on the shores of Yellowstone Lake. The heat source of the thermal features in this location is thought to be relatively close to the surface, only 10,000 feet (3,000 m) down. West Thumb is about the same size as another famous volcanic caldera, Crater Lake in Oregon, but much smaller than the great Yellowstone Caldera which last erupted about 640,000 years ago. West Thumb is a caldera within a caldera.
West Thumb was created approximately 162,000 years ago when a magma chamber bulged up under the surface of the earth and subsequently cracked it along ring fracture zones. This in turn released the enclosed magma as lava and caused the surface above the emptied magma chamber to collapse. Water later filled the collapsed area of the caldera, forming an extension of Yellowstone Lake. This created the source of heat and water that feed the West Thumb Geyser Basin today.
The thermal features at West Thumb are not only found on the lake shore, but extend under the surface of the lake as well. Several underwater hydrothermal features were discovered in the early 1990s and can be seen as slick spots or slight bulges in the summer. During the winter, the underwater thermal features are visible as melt holes in the icy surface of the lake. The surrounding ice can reach three feet (one yard) in thickness.
Perhaps the most famous hydrothermal feature at West Thumb is a geyser on the lake shore known as Fishing Cone. Walter Trumbull of the 1870 Washburn-Langford-Doane Expedition described a unique event while a man was fishing adjacent to the cone: "...in swinging a trout ashore, it accidentally got off the hook and fell into the spring. For a moment it darted about with wonderful rapidity, as if seeking an outlet. Then it came to the top, dead, and literally boiled." Fishing Cone erupted frequently to the height of 40 feet (12 m) in 1919 and to lesser heights in 1939. One fisherman was badly burned in Fishing Cone in 1921. Fishing at the geyser is now prohibited.
Early visitors would arrive at West Thumb via stagecoach from the Old Faithful area. They had a choice of continuing on the stagecoach or boarding the steamship Zillah to continue the journey by water to Lake Hotel. The boat dock was located near the south end of the geyser basin near Lakeside Spring.
Backcountry Geyser Basins
The Heart Lake 44°18′00″N 110°30′56″W, Lone Star 44°24′50″N 110°49′04″W, and Shoshone Geyser Basins 44°21′16″N 110°47′57″W are located away from the road and require at least several miles of hiking to reach. These areas lack the boardwalks and other safety features of the developed areas. As falling into geothermal features can be fatal, it is usually advisable to visit these areas with an experienced guide or at the very least, travelers need to ensure they remain on well-marked trails.
The Heart Lake Geyser Basin contains several groups of geysers and deep blue hot springs near Heart Lake in the south-central portion of Yellowstone, southeast of most of the main geyser basins. Lying in the Snake River watershed east of Lewis Lake and south of Yellowstone Lake, Heart Lake was named sometime before 1871 for Hart Hunney, a hunter. Other explorers in the region incorrectly assumed that the lake's name was spelled 'heart' because of its shape. The Heart Lake Geyser Basin begins a couple miles from the lake and descends along Witch Creek to the lakeshore. Five groups of hydrothermal features comprise the basin, and all of them contain geysers, although some are dormant.
Between Shoshone Lake and Old Faithful is the Lone Star Geyser Basin, of which the primary feature is Lone Star Geyser, named for its isolation from the nearby geysers of the Upper Geyser Basin. The basin is reachable on foot or bicycle via a 3 mile road that is closed to vehicles.
The Shoshone Geyser Basin, reached by hiking or by boat, contains one of the highest concentrations of geysers in the world – more than 80 in an area 1,600 by 800 feet (490 by 240 m). Hot springs and mudpots dot the landscape between the geyser basin and Shoshone Lake.
Hot Spring Basin is located 15 miles (24 km) north-northeast of Fishing Bridge and has one of Yellowstone's largest collections of hot springs and fumaroles. The geothermal features there release large amounts of sulfur. This makes water from the springs so acidic that it has dissolved holes in the pants of people who sit on wet ground and causes mounds of sulfur three feet (1 m) high to develop around fumaroles. The very hot acidic water and steam have also created voids in the ground that are only covered by a thin crust.
Mammoth Hot Springs is a large complex of hot springs on a hill of travertine in Yellowstone National Park adjacent to Fort Yellowstone and the Mammoth Hot Springs Historic District. It was created over thousands of years as hot water from the spring cooled and deposited calcium carbonate (over two tons flow into Mammoth each day in a solution). Because of the huge amount of geothermal vents, travertine flourishes. Although these springs lie outside the caldera boundary, their energy has been attributed to the same magmatic system that fuels other Yellowstone geothermal areas.
The thermal features at Mud Volcano and Sulphur Caldron are primarily mud pots and fumaroles because the area is situated on a perched water system with little water available. Fumaroles or "steam vents" occur when the ground water boils away faster than it can be recharged. Also, the vapors are rich in sulfuric acid that leaches the rock, breaking it down into clay. Because no water washes away the acid or leached rock, it remains as sticky clay to form a mud pot. Hydrogen sulfide gas is present deep in the earth at Mud Volcano and is oxidized to sulfuric acid by microbial activity, which dissolves the surface soils to create pools and cones of clay and mud. Along with hydrogen sulfide, steam, carbon dioxide, and other gases explode through the layers of mud.
A series of shallow earthquakes associated with the volcanic activity in Yellowstone struck this area in 1978. Soil temperatures increased to nearly 200 °F (93 °C). The slope between Sizzling Basin and Mud Geyser, once covered with green grass and trees, became a barren landscape of fallen trees known as "the cooking hillside".
Yellowstone National Park is a national park located in the western United States, largely in the northwest corner of Wyoming and extending into Montana and Idaho. It was established by the 42nd U.S. Congress with the Yellowstone National Park Protection Act 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. The park is known for its wildlife and its many geothermal features, especially the Old Faithful geyser, one of its most popular. While it represents many types of biomes, the subalpine forest is the most abundant. It is part of the South Central Rockies forests ecoregion.
While 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. Management and control of the park originally fell under the jurisdiction of the U.S. Department of the Interior, the first Secretary of the Interior to supervise the park being Columbus Delano. However, the U.S. Army was eventually commissioned to oversee the management of Yellowstone for 30 years between 1886 and 1916. In 1917, the administration of the park was transferred to the National Park Service, which had been created the previous year. Hundreds of structures have been built and are protected for their architectural and historical significance, and researchers have examined more than a thousand archaeological sites.
Yellowstone National Park spans an area of 3,468.4 sq mi (8,983 km2), comprising lakes, canyons, rivers, and mountain ranges. Yellowstone Lake is one of the largest high-elevation lakes in North America and is centered over the Yellowstone Caldera, the largest super volcano on the continent. The caldera is considered a dormant volcano. It has erupted with tremendous force several times in the last two million years. Well over half of the world's geysers and hydrothermal features are in Yellowstone, fueled by this ongoing volcanism. Lava flows 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.
Hundreds of species of mammals, birds, fish, reptiles, and amphibians 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 megafauna location in the contiguous United States. Grizzly bears, cougars, 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 large 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.
Teton County is a county in the U.S. state of Wyoming. As of the 2020 United States Census, the population was 23,331. Its county seat is Jackson. Its west boundary line is also the Wyoming state boundary shared with Idaho and the southern tip of Montana. Teton County is part of the Jackson, WY-ID Micropolitan Statistical Area.
Teton County contains the Jackson Hole ski area, all of Grand Teton National Park, and 40.4% of Yellowstone National Park's total area, including over 96.6% of its water area (largely in Yellowstone Lake).
Wyoming is a state in the Mountain West subregion of the Western United States. It borders Montana to the north and northwest, South Dakota and Nebraska to the east, Idaho to the west, Utah to the southwest, and Colorado to the south. With a population of 576,851 in 2020, Wyoming is the least populous state despite being the 10th largest by area, with the second-lowest population density after Alaska. The state capital and most populous city is Cheyenne, which had an estimated population of 63,957 in 2018.
Wyoming's western half consists mostly of the ranges and rangelands of the Rocky Mountains; its eastern half consists of high-elevation prairie, and is referred to as the High Plains. Wyoming's climate is semi-arid in some parts and continental in others, making it drier and windier overall than other states, with greater temperature extremes. The federal government owns just under half of Wyoming's land, generally protecting it for public uses. The state ranks sixth in the amount of land—-and fifth in the proportion of its land—-that is owned by the federal government. Its federal lands include two national parks (Grand Teton and Yellowstone), two national recreation areas, two national monuments, and several national forests, as well as historic sites, fish hatcheries, and wildlife refuges.
Indigenous peoples inhabited the region for thousands of years. Historic and currently federally recognized tribes include the Arapaho, Crow, Lakota, and Shoshone. Part of the land that is now Wyoming came under American sovereignty via the Louisiana Purchase, part via the Oregon Treaty, and, lastly, via the Mexican Cession. With the opening of the Oregon Trail, the Mormon Trail, and the California Trail, vast numbers of pioneers travelled through parts of the state that had once been traversed mainly by fur trappers, and this spurred the establishment of forts, such as Fort Laramie, that today serve as population centers. The Transcontinental Railroad supplanted the wagon trails in 1867 with a route through southern Wyoming, bringing new settlers and the establishment of founding towns, including the state capital of Cheyenne. On March 27, 1890, Wyoming became the union's 44th state.
Farming and ranching, and the attendant range wars, feature prominently in the state's history. Today, Wyoming's economy is largely based on tourism and the extraction of minerals such as coal, natural gas, oil, and trona. Its agricultural commodities include barley, hay, livestock, sugar beets, wheat, and wool.
Wyoming was the first state to allow women the right to vote (not counting New Jersey, which had allowed it until 1807), and the right to assume elected office, as well as the first state to elect a female governor. In honor of this part of its history, its most common nickname is "The Equality State" and its official state motto is "Equal Rights". It is among the least religious states in the country, and is known for having a political culture that leans towards libertarian conservatism. The Republican presidential nominee has carried the state in every election since 1968.
The Harshaw Creek fault zone has about 5 miles of left-lateral offset that probably occurred with the Jurassic island arc building. Superimposed on this is right-lateral strike-slip deformation that occurred in the Laramide arc building event. This exposure in the Harshaw Creek road is only a small part ot the deformation zone. Strike-slip faults have a distinct anastomosing-braided form in section and plan view as illustrated here.

Hello everyone. This is for update purposes. Let me start off my saying how nice it is that you all want updates, or some of you. There's something warming about people across the country and even the world who care and who are praying. The past few weeks have been rough on me and my family, but God is so good.
Alright, so...we(I, my sisters and my father) just got moved in and halfway settled down. Today is our first day with internet but it only connects to my sister's laptop for the time being so I won't really be able to get on unless I'm at school. That should change soon. The house still lacks furniture and not every box has been unpacked, but we have what we need now and things are going more smoothly there. Please be praying for my dad and his wife's relationship. For peace, wisdom in the decisions they make, and good communication. That's not why we moved out, but it doesn't make it any easier on them. I hope this isn't too personal to post. So much of it feels like my fault and it's hard to think about. So much of everything that is going on around me feels that way. It's hard to find comfort in anything or anyone.
Second thing I guess I want to mention is school. So far it's gone smoothly as well. The only exception would be my A&P class which is giving me a hard time. I have a big test tomorrow actually.
Last and definitely most importantly, would be my mom, June. Again, this is really personal and somewhat hard to mention. After thinking about it I realized that I shouldn't keep it to myself for sake of security when I can have all of you praying..not to mention all the emotional support I've gotten from you over the past 2 years. Anyway, the cancer has returned and her surgery to have the 3 tumors removed was today. She was under for about 6 hours but it went smoothly, God be praised. Just keep praying as she is recovering. Our prayer is that she will be cancer free after today, but they may decide to do chemotherapy if there are still traces of it when she recovers. Again, just be praying.

First visit of 2019 for me to this stunning castle today Thursday 28th March 2019.
Dunnottar Castle.
The rock the Castle sits upon was forced to the surface 440 million years ago during the Silurian period. A red rock conglomerate with boulders up to 1m across known as Pudding Stone is incredibly durable.
The ancient Highland rock pebbles and cementing matter is so tough that faults or cracks pass through the pebbles themselves.
I first visited Dunnottar Castle summer 2017, this magnificent castle sits high on a hill, last time I visited I captured my shots from the cliffs overlooking the site, though today I made the journey up the hill and entered the castle walls , wow what a magnificent experience, just perfect with loads of great photo opportunities to capture real Scottish history,after two hours wandering around and capturing as many shots that caught my eye , I made my way home, a magnificent experience indeed.
Dunnottar Castle (Scottish Gaelic: Dùn Fhoithear, "fort on the shelving slope" is a ruined medieval fortress located upon a rocky headland on the north-east coast of Scotland, about 3 kilometres (1.9 mi) south of Stonehaven.
The surviving buildings are largely of the 15th and 16th centuries, but the site is believed to have been fortified in the Early Middle Ages. Dunnottar has played a prominent role in the history of Scotland through to the 18th-century Jacobite risings because of its strategic location and defensive strength. Dunnottar is best known as the place where the Honours of Scotland, the Scottish crown jewels, were hidden from Oliver Cromwell's invading army in the 17th century. The property of the Keiths from the 14th century, and the seat of the Earl Marischal, Dunnottar declined after the last Earl forfeited his titles by taking part in the Jacobite rebellion of 1715.
The castle was restored in the 20th century and is now open to the public.
The ruins of the castle are spread over 1.4 hectares (3.5 acres), surrounded by steep cliffs that drop to the North Sea, 50 metres (160 ft) below. A narrow strip of land joins the headland to the mainland, along which a steep path leads up to the gatehouse.
The various buildings within the castle include the 14th-century tower house as well as the 16th-century palace. Dunnottar Castle is a scheduled monument, and twelve structures on the site are listed buildings.
History
Early Middle Ages
A chapel at Dunnottar is said to have been founded by St Ninian in the 5th century, although it is not clear when the site was first fortified, but in any case the legend is late and highly implausible. Possibly the earliest written reference to the site is found in the Annals of Ulster which record two sieges of "Dún Foither" in 681 and 694.
The earlier event has been interpreted as an attack by Brude, the Pictish king of Fortriu, to extend his power over the north-east coast of Scotland. The Scottish Chronicle records that King Domnall II, the first ruler to be called rí Alban (King of Alba), was killed at Dunnottar during an attack by Vikings in 900. King Aethelstan of Wessex led a force into Scotland in 934, and raided as far north as Dunnottar according to the account of Symeon of Durham. W. D. Simpson speculated that a motte might lie under the present caste, but excavations in the 1980s failed to uncover substantive evidence of early medieval fortification.
The discovery of a group of Pictish stones at Dunnicaer, a nearby sea stack, has prompted speculation that "Dún Foither" was actually located on the adjacent headland of Bowduns, 0.5 kilometres (0.31 mi) to the north.
Later Middle Ages
During the reign of King William the Lion (ruled 1165–1214) Dunnottar was a center of local administration for The Mearns. The castle is named in the Roman de Fergus, an early 13th-century Arthurian romance, in which the hero Fergus must travel to Dunnottar to retrieve a magic shield.
In May 1276 a church on the site was consecrated by William Wishart, Bishop of St Andrews. The poet Blind Harry relates that William Wallace captured Dunnottar from the English in 1297, during the Wars of Scottish Independence. He is said to have imprisoned 4,000 defeated English soldiers in the church and burned them alive.
In 1336 Edward III of England ordered William Sinclair, 8th Baron of Roslin, to sail eight ships to the partially ruined Dunnottar for the purpose of rebuilding and fortifying the site as a forward resupply base for his northern campaign. Sinclair took with him 160 soldiers, horses, and a corps of masons and carpenters.
Edward himself visited in July, but the English efforts were undone before the end of the year when the Scottish Regent Sir Andrew Murray led a force that captured and again destroyed the defences of Dunnottar.
In the 14th century Dunnottar was granted to William de Moravia, 5th Earl of Sutherland (d.1370), and in 1346 a licence to crenellate was issued by David II. Around 1359 William Keith, Marischal of Scotland, married Margaret Fraser, niece of Robert the Bruce, and was granted the barony of Dunnottar at this time. Keith then gave the lands of Dunnottar to his daughter Christian and son-in-law William Lindsay of Byres, but in 1392 an excambion (exchange) was agreed whereby Keith regained Dunnottar and Lindsay took lands in Fife.
William Keith completed construction of the tower house at Dunnottar, but was excommunicated for building on the consecrated ground associated with the parish church. Keith had provided a new parish church closer to Stonehaven, but was forced to write to the Pope, Benedict XIII, who issued a bull in 1395 lifting the excommunication.William Keith's descendents were created Earls Marischal in the mid 15th century, and they held Dunottar until the 18th century.
16th century rebuilding
Through the 16th century the Keiths improved and expanded their principal seats: at Dunnottar and also at Keith Marischal in East Lothian. James IV visited Dunnottar in 1504, and in 1531 James V exempted the Earl's men from military service on the grounds that Dunnottar was one of the "principall strenthis of our realme".
Mary, Queen of Scots, visited in 1562 after the Battle of Corrichie, and returned in 1564.
James VI stayed for 10 days in 1580, as part of a progress through Fife and Angus, during which a meeting of the Privy Council was convened at Dunnottar.
During a rebellion of Catholic nobles in 1592, Dunnottar was captured by a Captain Carr on behalf of the Earl of Huntly, but was restored to Lord Marischal just a few weeks later.
In 1581 George Keith succeeded as 5th Earl Marischal, and began a large scale reconstruction that saw the medieval fortress converted into a more comfortable home. The founder of Marischal College in Aberdeen, the 5th Earl valued Dunnottar as much for its dramatic situation as for its security.
A "palace" comprising a series of ranges around a quadrangle was built on the north-eastern cliffs, creating luxurious living quarters with sea views. The 13th-century chapel was restored and incorporated into the quadrangle.
An impressive stone gatehouse was constructed, now known as Benholm's Lodging, featuring numerous gun ports facing the approach. Although impressive, these are likely to have been fashionable embellishments rather than genuine defensive features.
Civil wars
Further information: Scotland in the Wars of the Three Kingdoms
In 1639 William Keith, 7th Earl Marischal, came out in support of the Covenanters, a Presbyterian movement who opposed the established Episcopal Church and the changes which Charles I was attempting to impose. With James Graham, 1st Marquess of Montrose, he marched against the Catholic James Gordon, 2nd Viscount Aboyne, Earl of Huntly, and defeated an attempt by the Royalists to seize Stonehaven. However, when Montrose changed sides to the Royalists and marched north, Marischal remained in Dunnottar, even when given command of the area by Parliament, and even when Montrose burned Stonehaven.
Marischal then joined with the Engager faction, who had made a deal with the king, and led a troop of horse to the Battle of Preston (1648) in support of the royalists.
Following the execution of Charles I in 1649, the Engagers gave their allegiance to his son and heir: Charles II was proclaimed king, arriving in Scotland in June 1650. He visited Dunnottar in July 1650, but his presence in Scotland prompted Oliver Cromwell to lead a force into Scotland, defeating the Scots at Dunbar in September 1650.
The Honours of Scotland
Charles II was crowned at Scone Palace on 1 January 1651, at which the Honours of Scotland (the regalia of crown, sword and sceptre) were used. However, with Cromwell's troops in Lothian, the honours could not be returned to Edinburgh. The Earl Marischal, as Marischal of Scotland, had formal responsibility for the honours, and in June the Privy Council duly decided to place them at Dunnottar.
They were brought to the castle by Katherine Drummond, hidden in sacks of wool. Sir George Ogilvie (or Ogilvy) of Barras was appointed lieutenant-governor of the castle, and given responsibility for its defence.
In November 1651 Cromwell's troops called on Ogilvie to surrender, but he refused. During the subsequent blockade of the castle, the removal of the Honours of Scotland was planned by Elizabeth Douglas, wife of Sir George Ogilvie, and Christian Fletcher, wife of James Granger, minister of Kinneff Parish Church. The king's papers were first removed from the castle by Anne Lindsay, a kinswoman of Elizabeth Douglas, who walked through the besieging force with the papers sewn into her clothes.
Two stories exist regarding the removal of the honours themselves. Fletcher stated in 1664 that over the course of three visits to the castle in February and March 1652, she carried away the crown, sceptre, sword and sword-case hidden amongst sacks of goods. Another account, given in the 18th century by a tutor to the Earl Marischal, records that the honours were lowered from the castle onto the beach, where they were collected by Fletcher's servant and carried off in a creel (basket) of seaweed. Having smuggled the honours from the castle, Fletcher and her husband buried them under the floor of the Old Kirk at Kinneff.
Meanwhile, by May 1652 the commander of the blockade, Colonel Thomas Morgan, had taken delivery of the artillery necessary for the reduction of Dunnottar. Ogilvie surrendered on 24 May, on condition that the garrison could go free. Finding the honours gone, the Cromwellians imprisoned Ogilvie and his wife in the castle until the following year, when a false story was put about suggesting that the honours had been taken overseas.
Much of the castle property was removed, including twenty-one brass cannons,[28] and Marischal was required to sell further lands and possessions to pay fines imposed by Cromwell's government.
At the Restoration of Charles II in 1660, the honours were removed from Kinneff Church and returned to the king. Ogilvie quarrelled with Marischal's mother over who would take credit for saving the honours, though he was eventually rewarded with a baronetcy. Fletcher was awarded 2,000 merks by Parliament but the sum was never paid.
Whigs and Jacobites
Religious and political conflicts continued to be played out at Dunnottar through the 17th and early 18th centuries. In 1685, during the rebellion of the Earl of Argyll against the new king James VII, 167 Covenanters were seized and held in a cellar at Dunnottar. The prisoners included 122 men and 45 women associated with the Whigs, an anti-Royalist group within the Covenanter movement, and had refused to take an oath of allegiance to the new king.
The Whigs were imprisoned from 24 May until late July. A group of 25 escaped, although two of these were killed in a fall from the cliffs, and another 15 were recaptured. Five prisoners died in the vault, and 37 of the Whigs were released after taking the oath of allegiance.
The remaining prisoners were transported to Perth Amboy, New Jersey, as part of a colonisation scheme devised by George Scot of Pitlochie. Many, like Scot himself, died on the voyage.
The cellar, located beneath the "King's Bedroom" in the 16th-century castle buildings, has since become known as the "Whigs' Vault".
Both the Jacobites (supporters of the exiled Stuarts) and the Hanoverians (supporters of George I and his descendents) used Dunnottar Castle. In 1689 during Viscount Dundee's campaign in support of the deposed James VII, the castle was garrisoned for William and Mary with Lord Marischal appointed captain.
Seventeen suspected Jacobites from Aberdeen were seized and held in the fortress for around three weeks, including George Liddell, professor of mathematics at Marischal College.
In the Jacobite Rising of 1715 George Keith, 10th Earl Marischal, took an active role with the rebels, leading cavalry at the Battle of Sheriffmuir. After the subsequent abandonment of the rising Lord Marischal fled to the Continent, eventually becoming French ambassador for Frederick the Great of Prussia. Meanwhile, in 1716, his titles and estates including Dunnottar were declared forfeit to the crown.
Later history
The seized estates of the Earl Marischal were purchased in 1720 for £41,172, by the York Buildings Company who dismantled much of the castle.
In 1761 the Earl briefly returned to Scotland and bought back Dunnottar only to sell it five years later to Alexander Keith, an Edinburgh lawyer who served as Knight Marischal of Scotland.
Dunnottar was inherited in 1852 by Sir Patrick Keith-Murray of Ochtertyre, who in turn sold it in July 1873 to Major Alexander Innes of Cowie and Raemoir for about £80,000.
It was purchased by Weetman Pearson, 1st Viscount Cowdray, in 1925 after which his wife embarked on a programme of repairs.
Since that time the castle has remained in the family, and has been open to the public, attracting 52,500 visitors in 2009.
Dunnottar Castle, and the headland on which is stands, was designated as a scheduled monument in 1970.In 1972 twelve of the structures at Dunnottar were listed.
Three buildings are listed at category A as being of "national importance": the keep; the entrance gateway; and Benholm's Lodging.
The remaining listings are at category B as being of "regional importance".[39] The Hon. Charles Anthony Pearson, the younger son of the 3rd Viscount Cowdray, currently owns and runs Dunnottar Castle which is part of the 210-square-kilometre (52,000-acre) Dunecht Estates.
Portions of the 1990 film Hamlet, starring Mel Gibson and Glenn Close, were shot there.
Description
Dunnottar's strategic location allowed its owners to control the coastal terrace between the North Sea cliffs and the hills of the Mounth, 3.5 kilometres (2.2 mi) inland, which enabled access to and from the north-east of Scotland.
The site is accessed via a steep, 800-metre (2,600 ft) footpath (with modern staircases) from a car park on the coastal road, or via a 3-kilometre (1.9 mi) cliff-top path from Stonehaven. Dunnottar's several buildings, put up between the 13th and 17th centuries, are arranged across a headland covering around 1.4 hectares (3.5 acres).
The dominant building, viewed from the land approach, is the 14th-century keep or tower house. The other principal buildings are the gatehouse; the chapel; and the 16th-century "palace" which incorporates the "Whigs' Vault".
Defences
The approach to the castle is overlooked by outworks on the "Fiddle Head", a promontory on the western side of the headland. The entrance is through the well-defended main gate, set in a curtain wall which entirely blocks a cleft in the rocky cliffs.
The gate has a portcullis and has been partly blocked up. Alongside the main gate is the 16th-century Benholm's Lodging, a five-storey building cut into the rock, which incorporated a prison with apartments above.
Three tiers of gun ports face outwards from the lower floors of Benholm's Lodging, while inside the main gate, a group of four gun ports face the entrance. The entrance passage then turns sharply to the left, running underground through two tunnels to emerge near the tower house.
Simpson contends that these defences are "without exception the strongest in Scotland", although later writers have doubted the effectiveness of the gun ports. Cruden notes that the alignment of the gun ports in Benholm's Lodging, facing across the approach rather than along, means that they are of limited efficiency.
The practicality of the gun ports facing the entrance has also been questioned, though an inventory of 1612 records that four brass cannons were placed here.
A second access to the castle leads up from a rocky cove, the aperture to a marine cave on the northern side of the Dunnottar cliffs into which a small boat could be brought. From here a steep path leads to the well-fortified postern gate on the cliff top, which in turn offers access to the castle via the Water Gate in the palace.
Artillery defences, taking the form of earthworks, surround the north-west corner of the castle, facing inland, and the south-east, facing seaward. A small sentry box or guard house stands by the eastern battery, overlooking the coast.
Tower house and surrounding buildings
The tower house of Dunnottar, viewed from the west
The late 14th-century tower house has a stone-vaulted basement, and originally had three further storeys and a garret above.
Measuring 12 by 11 metres (39 by 36 ft), the tower house stood 15 metres (49 ft) high to its gable. The principal rooms included a great hall and a private chamber for the lord, with bedrooms upstairs.
Beside the tower house is a storehouse, and a blacksmith's forge with a large chimney. A stable block is ranged along the southern edge of the headland. Nearby is Waterton's Lodging, also known as the Priest's House, built around 1574, possibly for the use of William Keith (died 1580), son of the 4th Earl Marischal.
This small self-contained house includes a hall and kitchen at ground level, with private chambers above, and has a projecting spiral stair on the north side. It is named for Thomas Forbes of Waterton, an attendant of the 7th Earl.
The palace
The palace, to the north-east of the headland, was built in the late 16th century and early to mid-17th century. It comprises three main wings set out around a quadrangle, and for the most part is probably the work of the 5th Earl Marischal who succeeded in 1581.
It provided extensive and comfortable accommodation to replace the rooms in the tower house. In its long, low design it has been compared to contemporary English buildings, in contrast to the Scottish tradition of taller towers still prevalent in the 16th century.
Seven identical lodgings are arranged along the west range, each opening onto the quadrangle and including windows and fireplace. Above the lodgings the west range comprised a 35-metre (115 ft) gallery. Now roofless, the gallery originally had an elaborate oak ceiling, and on display was a Roman tablet taken from the Antonine Wall.
At the north end of the gallery was a drawing room linked to the north range. The gallery could also be accessed from the Silver House to the south, which incorporated a broad stairway with a treasury above.
The basement of the north range incorporates kitchens and stores, with a dining room and great chamber above. At ground floor level is the Water Gate, between the north and west ranges, which gives access to the postern on the northern cliffs.
The east and north ranges are linked via a rectangular stair. The east range has a larder, brewhouse and bakery at ground level, with a suite of apartments for the Countess above. A north-east wing contains the Earl's apartments, and includes the "King's Bedroom" in which Charles II stayed. In this room is a carved stone inscribed with the arms of the 7th Earl and his wife, and the date 1654. Below these rooms is the Whigs' Vault, a cellar measuring 16 by 4.5 metres (52 by 15 ft). This cellar, in which the Covenanters were held in 1685, has a large eastern window, as well as a lower vault accessed via a trap-door in the floor.
Of the chambers in the palace, only the dining room and the Silver House remain roofed, having been restored in the 1920s. The central area contains a circular cistern or fish pond, 16 metres (52 ft) across and 7.6 metres (25 ft) deep, and a bowling green is located to the west.
At the south-east corner of the quadrangle is the chapel, consecrated in 1276 and largely rebuilt in the 16th century. Medieval walling and two 13th-century windows remain, and there is a graveyard to the south.

This month is #preparedness month at USGS. We'll be sharing information throughout the month related earthquakes, volcanoes, and other natural hazards as well as information about being informed and prepared for events like this.
This photo, taken in November 2002, shows USGS's Peter Haeussler preparing to measure the offset of a crevasse on the Canwell Glacier. On Nov 3, 2002 a M7.9 earthquake struck near Denali National Park in Alaska—the largest event on the Denali fault since 1912—and last 1-1/2 - 2 minutes. Although the Denali Fault shifted about 14 feet beneath the Trans-Alaska Oil Pipeline, the pipeline did not break, averting a major economic and environmental disaster. This was largely the result of stringent design specifications based on geologic studies done by the USGS and others 30 years earlier.
This is a youthful-appearing fault scarp south of Arsia Mons, also imaged by the Context Camera onboard MRO. Our resolution can help us determine if the scarp is indeed (geologically) fresh, or perhaps just buried by wind-driven sediment.
