the conversion of constantine
the conversion of constantine, and thereby the late roman empire, has had an enormous impact on world history. i have always wondered how a break away minor jewish sect based on the short and confused ministry of yeshua ben pantera was transformed into the christian juggernaut. the early christian community (from the death of yeshua to the 4th century) was an often persecuted lot. the common history is that christ appeared to constantine before the battle at pons milvius (where constantine was leading a machiavellian challenge for the control of the western half of the roman empire against the legitimate emperor) and bid him to follow the banner of the cross to victory. after said victory under said banner, constantine relaxed proscriptions against the christian community, and eventually adopted christianity as the legal state religion of the empire. this formal sanction led to the explosive political growth of the church [catholic and otherwise] and is the reason we worship christ the savior.
however, but for a figurative coin toss of history, we would be praying to mithra the redeemer. mithra who? you say. mithraism was another near east faith based on a son of god as savior motif very popular in the eastern half of the roman empire at the time of constantine.
mithra:
the cult of mithra (sidebar) was revered as a light-bringer, a protector and judge of immortal souls. mithra the god-figure remained celibate throughout his life, and valued self-control, renunciation and resistance to sensuality among his worshippers. mithras represented a system of ethics in which brotherhood was encouraged in order to unify against the forces of evil. mithraic rituals involved the symbolic consumption of wine/blood and bread/flesh, baptismal purification, and celebrated the birthday of mithra on december 25th. sound familar? consider then, that the myth of mithra predates christianity by many many centuries. cross-pollination of myths and ethos in the ancient near east was very common. it is important to understand that there is no single pure theology. they are all quilt-work.
the mithraic belief system was focused on the role of mithra as enforcer of truth. the avesta, the zoroastrian holy book, relates that ahura-mazda, the zoroaster Lord figure, sent mithra to guarantee the sanctity of promises and bonds. in fact, mithra is persian for 'contract'. mithras was worshipped as guardian of arms, and patron of soldiers and armies. the handshake was developed by those who worshipped him as a token of friendship and as a gesture to show that you were unarmed. when mithras later became the Roman god of contracts, the handshake gesture was imported throughout the mediterranean and europe by roman soldiers.
mithraism was adopted first by the roman legions garrisoned in the east during the republic. i presume they were attracted to its emphasis on honor, strength, and action. by the late empire under diocletian (284 - 305 AD), mithra was the de facto (and de jure) state religion. mithraic temples, known as mithraeum, were found at all corners of the empire, from northern england to northern africa.
mithraism was a revealed mystery faith. you did not merely convert to mithraism with a ritual baptism and declaration of submission. like the free masons, you had to be chosen and initiated in secret ceremonies into the ranks of the believers. perhaps this was a critical shortcoming of the faith in competition against the more liberal membership rites of christianity. an initiate was first required to prove their courage and strength in tests of danger (crossing swift rivers, jumping through fire bound and blindfolded, etc...) the mithraic initiation process led the acolyte through seven stages of greater revealed knowledge: Corax (Raven), Nymphus (Male Bride), Miles (Soldier), Leo (Lion), Peres (Persian), Heliodromus (Sun-Runner), and Pater (Father); each respective grade protected by Mercury, Venus, Mars, Jupiter, the Moon, the Sun, and Saturn.
mithraism was the faith of the realm for several centuries before constantine supplanted it. but for his conversion, the west, and the world would be a dramatically different place.
Old Royal Naval College - Painted Hall
The Old Royal Naval College is the architectural centrepiece of Maritime Greenwich, a World Heritage Site in Greenwich, London, described by the United Nations Educational, Scientific and Cultural Organisation (UNESCO) as being of "outstanding universal value" and reckoned to be the "finest and most dramatically sited architectural and landscape ensemble in the British Isles". The site is managed by the Greenwich Foundation for the Old Royal Naval College, set up in July 1998 as a registered charity to "look after these magnificent buildings and their grounds for the benefit of the nation". The grounds and some of its buildings are open to visitors. The buildings were originally constructed to serve as the Royal Hospital for Seamen at Greenwich, now generally known as Greenwich Hospital, which was designed by Christopher Wren, and built between 1696 and 1712. The hospital closed in 1869. Between 1873 and 1998 it was the Royal Naval College, Greenwich.
Origins of the site
This was originally the site of Bella Court, built by Humphrey, Duke of Gloucester, and subsequently renamed Palace of Placentia by Margaret of Anjou upon its confiscation. Rebuilt by Henry VII, it was thenceforth more commonly known as Greenwich Palace. As such, it was the birthplace of Tudor monarchs Henry VIII, Mary I, and Elizabeth I, and reputedly the favourite palace of Henry VIII. The palace fell into disrepair during the English Civil War. With the exception of the incomplete John Webb building, the palace was finally demolished in 1694.
Greenwich Hospital
In 1692 the Royal Hospital for Seamen at Greenwich was created on the site on the instructions of Mary II, who had been inspired by the sight of wounded sailors returning from the Battle of La Hogue. Architectural highlights included the Chapel and the Painted Hall. The Painted Hall was painted between 1707 and 1726 by Sir James Thornhill. The hospital closed in 1869 and the remains of thousands of sailors and officers were removed from the hospital site in 1875 and reinterred in East Greenwich Pleasaunce or "Pleasaunce Park".
Royal Naval College, Greenwich
In 1873, four years after the hospital closed, the buildings were converted to a training establishment for the Royal Navy. The Royal Navy finally left the College in 1998 when the site passed into the hands of the Greenwich Foundation for the Old Royal Naval College.
Greenwich Foundation for the Old Royal Naval College
Since 1998, the site has had new life breathed into it through a mix of new uses and activities and a revival of the historic old site under the management and control of the Greenwich Foundation. The buildings are Grade I listed. In 1999 some parts of Queen Mary and King William, and the whole of Queen Anne and the Dreadnought Building were leased for 150 years by the University of Greenwich. In 2000 Trinity College of Music leased the major part of King Charles. This created a unique new educational and cultural mix.
In 2002 the Foundation realised its aim of opening up the whole site to visitors. It opened the Painted Hall, the Chapel and the grounds and a Visitor Centre to the public daily, free of charge, with guided tours available. The Old Royal Naval College became open to students and visitors of all ages and nationalities accompanied often by music wafting from Trinity College. As Nathaniel Hawthorne wrote in 1863, "the people are sooner or later the legitimate inheritors of whatever beauty kings and queens create".
In 2005, the room where Nelson's coffin was held prior to his being laid-in-state was opened as the Nelson Room. The little side room contains a statue of Nelson replicating the one in Trafalgar Square, memorabilia, paintings and information. It can be seen on one of the guided tours that also include a visit to the undercrofts, the old skittle alley and crypt. A service is held in the chapel every Sunday at 11 am which is open to all. Public concerts are regularly held here and a wide variety of business and cultural events are held in the Painted Hall. The area is used by visitors, students, local people and film crews in a traffic-free environment that provides a variety of coffee shops, bars and restaurants, all incorporated within the old buildings, as part of a unique "ancient and modern" blend that support 21st century life in Greenwich.
The Old Royal Naval College and the "Maritime Greenwich" World Heritage site are becoming focal points for a wide range of business and community activities. Trinity College of Music provide a wide range of musicians and ensembles on a subsidised commercial basis to play at events throughout East London and beyond, part of their business and community “out-reach” policy encouraged and part-funded by the Higher Education Funding Council.
The site is regularly used for filming television programmes, television advertisements, and feature films. Productions have included Patriot Games, where an attack on a fictional royal family member, Lord Holmes, was filmed, as well as Shanghai Knights, and a 2006 television advertisement campaign for the British food and clothing retailer Marks & Spencer. Other films include Four Weddings and a Funeral, The Madness of King George, The Mummy Returns, The Avengers (1998) and Lara Croft: Tomb Raider (2001).
More recent filming has included BBC television's spy-drama Spooks and the dramatisation of Little Dorrit, David Cronenberg's film Eastern Promises, the film adaptation of Philip Pullman's novel Northern Lights and The Wolf Man (2009). The grounds were used extensively during the filming of 2006's Amazing Grace, and 2011's Sherlock Holmes: A Game of Shadows, Now You See Me 2 and Pirates of the Caribbean: On Stranger Tides. Scenes were shot at the grounds for The King's Speech, where the site doubled for Buckingham Palace, and The Dark Knight Rises, where it doubled for a cafe in the film's final scenes. In April 2012 the site was used for the iconic barricade scenes in the film adaption of the musical Les Miserables. In October 2012 the college was used for filming Thor: The Dark World. In October 2013 the college was used as a set for The Man from U.N.C.L.E.. Also Guy Richie's 2005 film Revolver filmed a scene there.
Painted Hall project
In 2014 the Old Royal Naval College announced that it was embarking on the next stage of its ambitious plans to restore the Painted Hall. Over three years 3,700 m2 of Thornhill’s masterpiece was to be conserved. The conservation project focused on the Lower Hall (the Upper Hall having been conserved in 2013). The project included a unique series of public 'ceiling tours' allowing members of the public to get up close to the painted ceiling and see conservators at work. In March 2019, the hall reopened to the public, the project winning awards.

Das (Old) Royal Naval College in Greenwich zählt zu den bedeutendsten Barockbauwerken in England und gehört seit 1997 zum UNESCO-Welterbe.
Geschichte
Nach der Stuart-Restauration plante Karl II. in Greenwich den Bau eines neuen königlichen Palastes anstelle des alten Palace of Placentia. Bis 1669 wurden jedoch nur der königliche Park angelegt und ein von John Webb entworfener Seitenflügel fertiggestellt, bevor der Bau aus finanziellen Gründen eingestellt wurde. Erst unter Wilhelm III. wurden die Baupläne wieder aufgegriffen. Da die Lage für die Gesundheit des an Asthma leidenden Königs nicht zuträglich war, entschlossen sich der König und Königin Maria unter dem Eindruck des englischen Seesiegs bei La Hougue und nach dem Vorbild des Hôtel des Invalides in Paris und des kurz vorher fertiggestellten Royal Hospital in Chelsea, anstelle eines Palastes ein Marinehospital für alte und verwundete Seeleute zu bauen. Die Entwürfe für das Royal Hospital for Seamen at Greenwich, gewöhnlich nur Greenwich Hospital genannt, lieferten Christopher Wren und sein Assistent Nicholas Hawksmoor ohne Bezahlung. Die Bauzeit an dem Komplex erstreckte sich über mehr als 30 Jahre, neben Wren und Hawksmoor arbeiteten die Architekten Campbell, Vanbrugh und Ripley an der Anlage. Die Kapelle wurde erst 1752 vollendet, doch die ersten Pensionäre zogen bereits 1705 ein. Gegen Ende des 18. Jahrhunderts lebten etwa 2000 Pensionäre in der Anlage.
In der Painted Hall, dem Speisesaal des Hospitals, lag 1805 der Leichnam Nelsons aufgebahrt. Vom Hospital wurde der Leichnam in einer offenen Staatsbarkasse, von einer prachtvollen Schiffsprozession begleitet, zur Grabstätte in die St Paul’s Cathedral überführt. Wegen Misswirtschaft und Korruption zogen im 19. Jahrhundert viele Pensionäre fort, 1869 wurde das Hospital geschlossen. Von 1873 bis 1998 dienten die Gebäude als Royal Naval College, das aus Portsmouth hierher verlegt wurde. Heute dienen die Gebäude der Universität Greenwich, im King Charles Court befindet sich das Trinity College of Music. Die Painted Hall und die Kapelle sind zu besichtigen, im nordwestlichen Gebäude ist ein Besucherzentrum. Seit 1997 gehören die Gebäude als Teil von Maritime Greenwich zum Weltkulturerbe der UNESCO.
Anlage
Beim Entwurf der Anlage bestand Königin Maria darauf, dass entgegen dem ursprünglichen Entwurf von John Webb das rückwärtig gelegene Queen’s House sichtbar bleiben und dieses in die zentrale Blickachse mit eingezogen werden müsse. Wren entschied sich, vier symmetrisch zur Mittelachse orientierte Bauten zu errichten, die jeweils einen Innenhof umschließen. Dabei bezog er den bis 1669 als Seitenflügel des neuen Königspalastes errichteten Bau mit ein. Diesem King Charles Court genannten Bau gegenüber entstand bis 1729 der Queen Anne Court. Die beiden rückwärtigen Bauten werden als King William Court und Queen Mary Court bezeichnet. Die perspektivisch eingerückten Zwillingsbauten setzen mit ihren Kuppeln optische Akzente und geben den Blick auf das Queen’s House frei.
In dem westlich gelegenen King William Court befindet sich die Painted Hall, die ursprünglich als Speisesaal der Pensionäre geplant war. Der Saal besteht mit Vestibül, Lower und Upper Hall aus drei verschiedenen Ebenen und gilt mit seiner Wand- und Deckenbemalung als Höhepunkt der englischen Barockmalerei. Die Malereien stammen von James Thornhill, der allein an dem Deckengemälde Der Triumph der protestantischen Thronfolge 20 Jahre lang gearbeitet hat.
Das Gegenstück zur Painted Hall ist die Kapelle im Queen Mary Court. Nach einem Entwurf von Wren wurde sie erst 1752 von Thomas Ripley fertiggestellt. Nachdem sie 1772 ausgebrannt war, wurde sie bis 1779 von James „Athenian“ Stuart neu gestaltet. Der klassizistisch ausgestattete Raum ist für seine gute Akustik bekannt.

I've had these laying around for 4 years and have never really use them. What sort of value do they have now?
Japanese textiles at Kiriko, Portland, Oregon
From Kiriko's Web site:
Kiriko is a lifestyle brand forged from the spirit of Mottainai (勿体無い); a Japanese value that embraces one to waste nothing and recycle everything.
Long ago, cloth was hand-woven with patterns that held meaning and dyed with materials available through the seasons. In this way we cycled with the seasons, not trends. We made memories with our belongings instead of replace them with mass produced goods. When we began to lose touch with the tradition of making in this way, we stopped treasuring our clothes.
"We believe fabric is everything."
We are always searching Japan for vibrant Kasuri - both vintage and those made today in craft houses generations’ old, hand-dyed Shibori, and centuries old Boros. Our apparel and accessories display the incredible traditional craftsmanship and care small textile factories in Japan boast. By purchasing our products, you are not only helping Kiriko Made as a small emerging brand, but also all the factories in Japan that create the materials we are fortunate enough to use.
Wear them, love them, and hand them down.
Add another chapter to their story.
The area that was to become West Palm Beach was settled in the late 1870s and 1880s by a few hundred settlers who called the vicinity "Lake Worth Country." These settlers were a diverse community from different parts of the United States and the world. They included founding families such at the Potters and the Lainharts, who would go on to become leading members of the business community in the fledgling city. The first white settlers in Palm Beach County lived around Lake Worth, then an enclosed freshwater lake, named for Colonel William Jenkins Worth, who had fought in the Second Seminole War in Florida in 1842. Most settlers engaged in the growing of tropical fruits and vegetables for shipment the north via Lake Worth and the Indian River. By 1890, the U.S. Census counted over 200 people settled along Lake Worth in the vicinity of what would become West Palm Beach. The area at this time also boasted a hotel, the "Cocoanut House", a church, and a post office. The city was platted by Henry Flagler as a community to house the servants working in the two grand hotels on the neighboring island of Palm Beach, across Lake Worth in 1893, coinciding with the arrival of the Florida East Coast railroad. Flagler paid two area settlers, Captain Porter and Louie Hillhouse, a combined sum of $45,000 for the original town site, stretching from Clear Lake to Lake Worth.
On November 5, 1894, 78 people met at the "Calaboose" (the first jail and police station located at Clematis St. and Poinsettia, now Dixie Hwy.) and passed the motion to incorporate the Town of West Palm Beach in what was then Dade County (now Miami-Dade County). This made West Palm Beach the first incorporated municipality in Dade County and in South Florida. The town council quickly addressed the building codes and the tents and shanties were replaced by brick, brick veneer, and stone buildings. The city grew steadily during the 1890s and the first two decades of the 20th century, most residents were engaged in the tourist industry and related services or winter vegetable market and tropical fruit trade. In 1909, Palm Beach County was formed by the Florida State Legislature and West Palm Beach became the county seat. In 1916, a new neo-classical courthouse was opened, which has been painstakingly restored back to its original condition, and is now used as the local history museum.
The city grew rapidly in the 1920s as part of the Florida land boom. The population of West Palm Beach quadrupled from 1920 to 1927, and all kinds of businesses and public services grew along with it. Many of the city's landmark structures and preserved neighborhoods were constructed during this period. Originally, Flagler intended for his Florida East Coast Railway to have its terminus in West Palm, but after the area experienced a deep freeze, he chose to extend the railroad to Miami instead.
The land boom was already faltering when city was devastated by the 1928 Okeechobee hurricane. The Depression years of the 1930s were a quiet time for the area, which saw slight population growth and property values lower than during the 1920s. The city only recovered with the onset of World War II, which saw the construction of Palm Beach Air Force Base, which brought thousands of military personnel to the city. The base was vital to the allied war effort, as it provided an excellent training facility and had unparalleled access to North Africa for a North American city. Also during World War II, German U-Boats sank dozens of merchant ships and oil tankers just off the coast of West Palm Beach. Nearby Palm Beach was under black out conditions to minimize night visibility to German U-boats.
The 1950s saw another boom in population, partly due to the return of many soldiers and airmen who had served in the vicinity during the war. Also, the advent of air conditioning encouraged growth, as year-round living in a tropical climate became more acceptable to northerners. West Palm Beach became the one of the nation's fastest growing metropolitan areas during the 1950s; the city's borders spread west of Military Trail and south to Lake Clarke Shores. However, many of the city's residents still lived within a narrow six-block wide strip from the south to north end. The neighborhoods were strictly segregated between White and African-American populations, a legacy that the city still struggles with today. The primary shopping district remained downtown, centered around Clematis Street.
In the 1960s, Palm Beach County's first enclosed shopping mall, the Palm Beach Mall, and an indoor arena were completed. These projects led to a brief revival for the city, but in the 1970s and 1980s crime continued to be a serious issue and suburban sprawl continued to drain resources and business away from the old downtown area. By the early 1990s there were very high vacancy rates downtown, and serious levels of urban blight.
Since the 1990s, developments such as CityPlace and the preservation and renovation of 1920s architecture in the nightlife hub of Clematis Street have seen a downtown resurgence in the entertainment and shopping district. The city has also placed emphasis on neighborhood development and revitalization, in historic districts such as Northwood, Flamingo Park, and El Cid. Some neighborhoods still struggle with blight and crime, as well as lowered property values caused by the Great Recession, which hit the region particularly hard. Since the recovery, multiple new developments have been completed. The Palm Beach Mall, located at the Interstate 95/Palm Beach Lakes Boulevard interchange became abandoned as downtown revitalized - the very mall that initiated the original abandonment of the downtown. The mall was then redeveloped into the Palm Beach Fashion Outlets in February 2014. A station for All Aboard Florida, a high-speed passenger rail service serving Miami, Fort Lauderdale, West Palm Beach, and Orlando, is under construction as of July 2015.

Today I want to teach you a German word that doesn’t exist in other languages: “verbuscht”. It is related to the German word “Busch”. Which means “bush”.
In its original meaning, “verbuscht” described a form of land degradation. When forests are cleared or agricultural plots are abandoned, the result is often worthless shrubland, with little ecological or economic value and not much biodiversity. It takes years and lots of effort make the “verbuscht” land useful again.
In post-colonial times Germans started to apply the term also to human beings, particularly development workers. In this context it does not mean that men have turned to bushes, but that they have spent too much time “in the bush”.
A fitting expression. The sense of degradation is still there and the expression makes good use of the fact that the German word “Busch” has the same double meaning as “bush” in English: It not only describes a shape of plant, but also a kind of wilderness in tropical countries, as in “bushwacker” or “bushman”.
When I hear the word “verbuscht”, I imagine an aging, overweight white male human in an exotic country, sitting at a swimming pool with a glass of gin tonic in a club where only other foreigners are admitted as members. Only the waiters are local. He is fluent in several languages and has outgrown the phase of “culture shock” decades ago.
This image already includes many things that are good and bad in the lives of long-term expatriates. They have widened their horizons by living in foreign cultures and have gained skills and knowledge that their compatriots lack. They live a comfortable life in relative luxury, which they would not enjoy at home. But they are isolated and lonesome. They don’t have much of a family life and belong to neither to host society nor to their home country. They have a local spouse, a beautiful woman half their age, but only after having gone through a painful divorce - or several divorces. Alcoholism is a common disease.
Nowadays the expression is no longer used for development workers only, but also for engineers and managers of commercial companies sent to work abroad for too long. And few expatriates still spend much time in the “bush”. You are more likely to find them in urban office towers and meeting rooms. But all of them are still prone to getting “verbuscht”.
I googled a bit to learn more about it. I expected to find some interesting sociological or psychological studies. Lists of symptoms and tips to deal with them. But to my surprise, I found almost nothing, although I’m sure the phenomenon is widespread. The few sources online seem to assume that the problems of being “verbuscht” only start when the expatriate returns home: He is useless at work because the job descriptions at the headquarters were not made with his unusual skills profile in mind. He doesn’t understand the changes in his home country that happened during his absence. He is frustrated because he used to have a respected leadership position but now sits in a small corner office and has nothing important to do. He is grumpy because he used to have a driver and a housekeeper, and now has to make his own coffee. Nobody wants to hear about his adventures. His ties are out of fashion. He is bored.
Am I?
If a nation values anything more than freedom, it will lose its freedom;
and the irony of it is that if it is comfort or money it values more, it
will lose that, too.

DAY 09: Destination – KORZOK
Distance & Time: Shey – Korzok by car - 220 km / 7 hrs.
--------------------------------------------------------------------------------------------------------------------------------------
Photo opportunity seems absurd; it is impossible not to try. Picking up the gear bag, we head towards the herd. The even land exposing at both ends, the sun behind the cloud cover sending shivers but merciless when out.
The walk is never ending, the heat unbearable and the wind forceful. Knowing fully well that we should give up this pursuit but it is obstinacy that drives on. Glad to remember that the minimum distance to be maintained is 3 km / 1.86 miles if we are not to disturb the animals. This translates into less space to be covered!
Three of the kiangs are nearer than the others and have spotted us, signal Tashi to make no sudden movements as that might alarm them. The thumping of heartbeat seems overtly loud in this oddly tense moment. With slow deliberation lift the camera, aim and get into a shooting frenzy. Just for a few seconds perhaps before a single from the herd stomp it’s feet and break into a swift gallop, others immediately follow; we watch fascinated.
Must get back to the car and drive on, Korzok is still far. Turning back a gasp escapes, the car looks not any larger than a spec in the horizon! Tracking kiangs we had lost the sense of distance.

Kiang also known as Tibetan Ass or Asiatic Ass (Equus kiang) is a species that possess a keen eyesight and well-developed sense of smell. It feeds on grass and herbs. The genders are alike and weigh between 250 – 380 kg / 551 – 838 lbs., adding about 10 kg / 22 lbs. fat towards winter. Longevity is reported to be about 20 years. A social animal, it lives mostly in sexually separated hordes of 10 – 40 individuals in high altitude, open bleak semi-deserts, steppes, grassy rolling tablelands and soft sandy slopes, often near marshes or springs. Actively grazes throughout the day and can stay without water for quite some time. When alarmed, the entire group flees in a straight gallop (easily reaching the speed of 60km / 37 miles per hour). Resident throughout east and north Ladakh can be found between 4, 000 – 5, 200m / 13, 123 – 17, 060 ft. altitudes, occasionally even higher. The species however moves considerably back and forth across the Tibetan border, very often related to direct disturbance and human presence/absence. An estimated more than 2000 kiang are surviving in Ladakh. Natural predators include mainly wolf and Tibetan wild-dog, which hunts foals, old and injured or sick animals.

Arches National Park is a national park in eastern Utah, United States. The park is adjacent to the Colorado River, 4 miles (6 km) north of Moab, Utah. More than 2,000 natural sandstone arches are located in the park, including the well-known Delicate Arch, as well as a variety of unique geological resources and formations. The park contains the highest density of natural arches in the world.
The park consists of 310.31 square kilometres (76,680 acres; 119.81 sq mi; 31,031 ha) of high desert located on the Colorado Plateau. The highest elevation in the park is 5,653 feet (1,723 m) at Elephant Butte, and the lowest elevation is 4,085 feet (1,245 m) at the visitor center. The park receives an average of less than 10 inches (250 mm) of rain annually.
Administered by the National Park Service, the area was originally named a national monument on April 12, 1929, and was re designated as a national park on November 12, 1971. The park received more than 1.6 million visitors in 2018.
As stated in the foundation document in U.S. National Park Service website:
The purpose of Arches National Park is to protect extraordinary examples of geologic features including arches, natural bridges, windows, spires, and balanced rocks, as well as other features of geologic, historic, and scientific interest, and to provide opportunities to experience these resources and their associated values in their majestic natural settings.
The national park lies above an underground evaporite layer or salt bed, which is the main cause of the formation of the arches, spires, balanced rocks, sandstone fins, and eroded monoliths in the area. This salt bed is thousands of feet thick in places and was deposited in the Paradox Basin of the Colorado Plateau some 300 million years ago (Mya) when a sea flowed into the region and eventually evaporated. Over millions of years, the salt bed was covered with debris eroded from the Uncompahgre Uplift to the northeast. During the Early Jurassic (about 200 Mya), desert conditions prevailed in the region and the vast Navajo Sandstone was deposited. An additional sequence of stream laid and windblown sediments, the Entrada Sandstone (about 140 Mya), was deposited on top of the Navajo. Over 5,000 feet (1,500 m) of younger sediments were deposited and have been mostly eroded. Remnants of the cover exist in the area including exposures of the Cretaceous Mancos Shale. The arches of the area are developed mostly within the Entrada formation.
The weight of this cover caused the salt bed below it to liquefy and thrust up layers of rock into salt domes. The evaporites of the area formed more unusual "salt anticlines" or linear regions of uplift. Faulting occurred and whole sections of rock subsided into the areas between the domes. In some places, they turned almost on edge. The result of one such 2,500-foot (760 m) displacement, the Moab Fault, is seen from the visitor center.
As this subsurface movement of salt shaped the landscape, erosion removed the younger rock layers from the surface. Except for isolated remnants, the major formations visible in the park today are the salmon-colored Entrada Sandstone, in which most of the arches form, and the buff-colored Navajo Sandstone. These are visible in layer-cake fashion throughout most of the park. Over time, water seeped into the surface cracks, joints, and folds of these layers. Ice formed in the fissures, expanding and putting pressure on surrounding rock, breaking off bits and pieces. Winds later cleaned out the loose particles. A series of free-standing fins remained. Wind and water attacked these fins until, in some, the cementing material gave way and chunks of rock tumbled out. Many damaged fins collapsed. Others, with the right degree of hardness and balance, survived despite their missing sections. These became the famous arches.
Although the park's terrain may appear rugged and durable, it is extremely fragile. More than 1 million visitors each year threaten the fragile high-desert ecosystem. The problem lies within the soil's crust, which is composed of cyanobacteria, algae, fungi, and lichens that grow in the dusty parts of the park. Factors that make Arches National Park sensitive to visitor damage include being a semiarid region, the scarce, unpredictable rainfall, lack of deep freezing, and lack of plant litter, which results in soils that have both a low resistance to and slow recovery from, compressional forces such as foot traffic. Methods of indicating effects on the soil are cytophobic soil crust index, measuring of water infiltration, and t-tests that are used to compare the values from the undisturbed and disturbed areas.
Geological processes that occurred over 300 million years ago caused a salt bed to be deposited, which today lies beneath the landscape of Arches National Park.[ Over time, the salt bed was covered with sediments that eventually compressed into rock layers that have since been named Entrada Standstone. Rock layers surrounding the edge of the salt bed continued to erode and shift into vertical sandstone walls called fins. Sand collected between vertical walls of the fins, then slightly acidic rain combined with carbon dioxide in the air allowed for the chemical formation of carbonic acid within the trapped sand. Over time, the carbonic acid dissolved the calcium carbonate that held the sandstone together. Many of the rock formations have weaker layers of rock on bottom that are holding stronger layers on top. The weaker layers would dissolve first, creating openings in the rock. Gravity caused pieces of the stronger rock layer to fall piece by piece into an arch shape. Arches form within rock fins at points of intense fracturing localization, or weak points in the rock's formation, caused by horizontal and vertical discontinuities. Lastly, water, wind, and time continued this erosion process and ultimately created the arches of Arches National Park. All of the arches in the park are made of Entrada Sandstone, however, there are slight differences in how each arch was developed. This allows the Entrada Sandstone to be categories into 3 groups including Slick rock members, Dewey rock members, and Moab members. Vertical arches can be developed from Slick rock members, a combination of Slick rock members and Moab members, or Slick rock members resting above Dewey rock members. Horizontal arches (also called potholes) are formed when a vertical pothole formation meets a horizontal cave, causing a union into a long arch structure. The erosion process within Arches National Park will continue as time continues to pass. Continued erosion combined with vertical and horizontal stress will eventually cause arches to collapse, but still, new arches will continue to form for thousands of years.
Humans have occupied the region since the last ice age 10,000 years ago. Fremont people and Ancestral Puebloans lived in the area until about 700 years ago. Spanish missionaries encountered Ute and Paiute tribes in the area when they first came through in 1775, but the first European-Americans to attempt settlement in the area were the Mormon Elk Mountain Mission in 1855, who soon abandoned the area. Ranchers, farmers, and prospectors later settled Moab in the neighboring Riverine Valley in the late 1870s. Word of the beauty of the surrounding rock formations spread beyond the settlement as a possible tourist destination.
The Arches area was first brought to the attention of the National Park Service by Frank A. Wadleigh, passenger traffic manager of the Denver and Rio Grande Western Railroad. Wadleigh, accompanied by railroad photographer George L. Beam, visited the area in September 1923 at the invitation of Alexander Ringhoffer, a Hungarian-born prospector living in Salt Valley. Ringhoffer had written to the railroad to interest them in the tourist potential of a scenic area he had discovered the previous year with his two sons and a son-in-law, which he called the Devils Garden (known today as the Klondike Bluffs). Wadleigh was impressed by what Ringhoffer showed him, and suggested to Park Service director Stephen T. Mather that the area be made a national monument.
The following year, additional support for the monument idea came from Laurence Gould, a University of Michigan graduate student (and future polar explorer) studying the geology of the nearby La Sal Mountains, who was shown the scenic area by local physician Dr. J. W. "Doc" Williams.
A succession of government investigators examined the area, in part due to confusion as to the precise location. In the process, the name Devils Garden was transposed to an area on the opposite side of Salt Valley that includes Landscape Arch, the longest arch in the park. Ringhoffer's original discovery was omitted, while another area nearby, known locally as the Windows, was included. Designation of the area as a national monument was supported by the Park Service in 1926 but was resisted by President Calvin Coolidge's Interior Secretary, Hubert Work. Finally, in April 1929, shortly after his inauguration, President Herbert Hoover signed a presidential proclamation creating the Arches National Monument, consisting of two comparatively small, disconnected sections. The purpose of the reservation under the 1906 Antiquities Act was to protect the arches, spires, balanced rocks, and other sandstone formations for their scientific and educational value. The name Arches was suggested by Frank Pinkely, superintendent of the Park Service's southwestern national monuments, following a visit to the Windows section in 1925.
In late 1938, President Franklin D. Roosevelt signed a proclamation that enlarged the Arches to protect additional scenic features and permit the development of facilities to promote tourism. A small adjustment was made by President Dwight Eisenhower in 1960 to accommodate a new road alignment.
In early 1969, just before leaving office, President Lyndon B. Johnson signed a proclamation substantially enlarging the Arches. Two years later, President Richard Nixon signed legislation enacted by Congress, which significantly reduced the total area enclosed, but changed its status. Arches National Park was formally dedicated in May 1972.
In 1980, vandals attempted to use an abrasive kitchen cleanser to deface ancient petroglyphs in the park, prompting park officials to recruit physicist John F. Asmus, who specialized in using lasers to restore works of art, to use his technology to repair the damage. Asmus "zapped the panel with intense light pulses and succeeded in removing most of the cleanser".
Climbing Balanced Rock or any named or unnamed arch in Arches National Park with an opening larger than 3 ft (0.9 m) is banned by park regulations. Climbing on other features in the park is allowed but regulated; in addition, slacklining and BASE jumping are banned parkwide.
Climbing on named arches within the park had long been banned by park regulations, but following Dean Potter's successful free climb on Delicate Arch in May 2006, the wording of the regulations was deemed unenforceable by the park attorney. In response, the park revised its regulations later that month, eventually imposing the current ban on arch climbing in 2014.
Approved recreational activities include auto touring, hiking, bicycling, camping at the Devils Garden campground, backpacking, canyoneering, and rock climbing, with permits required for the last three activities. Guided commercial tours and ranger programs are also available.
Astronomy is also popular in the park due to its dark skies, despite the increasing light pollution from towns such as Moab.
Delicate Arch is the subject of the third 2014 quarter of the U.S. Mint's America the Beautiful Quarters program commemorating national parks and historic sites. The Arches quarter had the highest production of the five 2014 national park quarters, with more than 465 million minted.
American writer Edward Abbey was a park ranger at Arches National Monument in 1956 and 1957, where he kept journals that became his book Desert Solitaire. The success of Abbey's book, as well as interest in adventure travel, has drawn many hikers, mountain bikers, and off-pavement driving enthusiasts to the area. Permitted activities within the park include camping, hiking along designated trails, backpacking, canyoneering, rock climbing, bicycling, and driving along existing roads, both paved and unpaved. The Hayduke Trail, an 812 mi (1,307 km) backpacking route named after one of Edward Abbey's characters, begins in the park.
An abundance of wildlife occurs in Arches National Park, including spadefoot toads, antelope squirrels, scrub jays, peregrine falcons, many kinds of sparrows, red foxes, desert bighorn sheep, kangaroo rats, mule deers, cougars, midget faded rattlesnakes, yucca moths, western rattlesnakes, and collared lizards.
A number of plant species are common in the park, including prickly pear cactus, Indian ricegrass, bunch grasses, cheatgrass, moss, liverworts, Utah juniper, Mormon tea, blackbrush, cliffrose, four-winged saltbrush, pinyon pine, evening primrose, sand verbena, yucca, and sacred datura.
Biological soil crust consisting of cyanobacteria, lichen, mosses, green algae, and microfungi is found throughout southeastern Utah. The fibrous growths help keep soil particles together, creating a layer that is more resistant to erosion. The living soil layer readily absorbs and stores water, allowing more complex forms of plant life to grow in places with low precipitation levels.
Among the notable features of the park are the following:
Balanced Rock – a large balancing rock, the size of three school buses
Courthouse Towers – a collection of tall stone columns
Dark Angel – a free-standing 150 ft-tall (46 m) sandstone pillar at the end of the Devils Garden Trail
Delicate Arch – a lone-standing arch that has become a symbol of Utah and the most recognized arch in the park
Devils Garden – many arches and columns scattered along a ridge
Double Arch – two arches that share a common end
Fiery Furnace – an area of maze-like narrow passages and tall rock columns (see biblical reference, Book of Daniel, chapter 3)
Landscape Arch – a very thin and long arch in the Devils Garden with a span of 290 ft (88 m) (the longest arch in the park)
Petrified Dunes – petrified remnants of dunes blown from the ancient lakes that covered the area
The Phallus – a rock spire that resembles a phallus
Wall Arch – located along the popular Devils Garden Trail; collapsed sometime on August 4/5, 2008
The Three Gossips –a mid-sized sandstone tower located in the Courthouse Towers area.
Utah is a landlocked state in the Mountain West subregion of the Western United States. It borders Colorado to its east, Wyoming to its northeast, Idaho to its north, Arizona to its south, and Nevada to its west. Utah also touches a corner of New Mexico in the southeast. Of the fifty U.S. states, Utah is the 13th-largest by area; with a population over three million, it is the 30th-most-populous and 11th-least-densely populated. Urban development is mostly concentrated in two areas: the Wasatch Front in the north-central part of the state, which is home to roughly two-thirds of the population and includes the capital city, Salt Lake City; and Washington County in the southwest, with more than 180,000 residents. Most of the western half of Utah lies in the Great Basin.
Utah has been inhabited for thousands of years by various indigenous groups such as the ancient Puebloans, Navajo, and Ute. The Spanish were the first Europeans to arrive in the mid-16th century, though the region's difficult geography and harsh climate made it a peripheral part of New Spain and later Mexico. Even while it was Mexican territory, many of Utah's earliest settlers were American, particularly Mormons fleeing marginalization and persecution from the United States via the Mormon Trail. Following the Mexican–American War in 1848, the region was annexed by the U.S., becoming part of the Utah Territory, which included what is now Colorado and Nevada. Disputes between the dominant Mormon community and the federal government delayed Utah's admission as a state; only after the outlawing of polygamy was it admitted in 1896 as the 45th.
People from Utah are known as Utahns. Slightly over half of all Utahns are Mormons, the vast majority of whom are members of the Church of Jesus Christ of Latter-day Saints (LDS Church), which has its world headquarters in Salt Lake City; Utah is the only state where a majority of the population belongs to a single church. A 2023 paper challenged this perception (claiming only 42% of Utahns are Mormons) however most statistics still show a majority of Utah residents belong to the LDS church; estimates from the LDS church suggests 60.68% of Utah's population belongs to the church whilst some sources put the number as high as 68%. The paper replied that membership count done by the LDS Church is too high for several reasons. The LDS Church greatly influences Utahn culture, politics, and daily life, though since the 1990s the state has become more religiously diverse as well as secular.
Utah has a highly diversified economy, with major sectors including transportation, education, information technology and research, government services, mining, multi-level marketing, and tourism. Utah has been one of the fastest growing states since 2000, with the 2020 U.S. census confirming the fastest population growth in the nation since 2010. St. George was the fastest-growing metropolitan area in the United States from 2000 to 2005. Utah ranks among the overall best states in metrics such as healthcare, governance, education, and infrastructure. It has the 12th-highest median average income and the least income inequality of any U.S. state. Over time and influenced by climate change, droughts in Utah have been increasing in frequency and severity, putting a further strain on Utah's water security and impacting the state's economy.
The History of Utah is an examination of the human history and social activity within the state of Utah located in the western United States.
Archaeological evidence dates the earliest habitation of humans in Utah to about 10,000 to 12,000 years ago. Paleolithic people lived near the Great Basin's swamps and marshes, which had an abundance of fish, birds, and small game animals. Big game, including bison, mammoths and ground sloths, also were attracted to these water sources. Over the centuries, the mega-fauna died, this population was replaced by the Desert Archaic people, who sheltered in caves near the Great Salt Lake. Relying more on gathering than the previous Utah residents, their diet was mainly composed of cattails and other salt tolerant plants such as pickleweed, burro weed and sedge. Red meat appears to have been more of a luxury, although these people used nets and the atlatl to hunt water fowl, ducks, small animals and antelope. Artifacts include nets woven with plant fibers and rabbit skin, woven sandals, gaming sticks, and animal figures made from split-twigs. About 3,500 years ago, lake levels rose and the population of Desert Archaic people appears to have dramatically decreased. The Great Basin may have been almost unoccupied for 1,000 years.
The Fremont culture, named from sites near the Fremont River in Utah, lived in what is now north and western Utah and parts of Nevada, Idaho and Colorado from approximately 600 to 1300 AD. These people lived in areas close to water sources that had been previously occupied by the Desert Archaic people, and may have had some relationship with them. However, their use of new technologies define them as a distinct people. Fremont technologies include:
use of the bow and arrow while hunting,
building pithouse shelters,
growing maize and probably beans and squash,
building above ground granaries of adobe or stone,
creating and decorating low-fired pottery ware,
producing art, including jewelry and rock art such as petroglyphs and pictographs.
The ancient Puebloan culture, also known as the Anasazi, occupied territory adjacent to the Fremont. The ancestral Puebloan culture centered on the present-day Four Corners area of the Southwest United States, including the San Juan River region of Utah. Archaeologists debate when this distinct culture emerged, but cultural development seems to date from about the common era, about 500 years before the Fremont appeared. It is generally accepted that the cultural peak of these people was around the 1200 CE. Ancient Puebloan culture is known for well constructed pithouses and more elaborate adobe and masonry dwellings. They were excellent craftsmen, producing turquoise jewelry and fine pottery. The Puebloan culture was based on agriculture, and the people created and cultivated fields of maize, beans, and squash and domesticated turkeys. They designed and produced elaborate field terracing and irrigation systems. They also built structures, some known as kivas, apparently designed solely for cultural and religious rituals.
These two later cultures were roughly contemporaneous, and appear to have established trading relationships. They also shared enough cultural traits that archaeologists believe the cultures may have common roots in the early American Southwest. However, each remained culturally distinct throughout most of their existence. These two well established cultures appear to have been severely impacted by climatic change and perhaps by the incursion of new people in about 1200 CE. Over the next two centuries, the Fremont and ancient Pueblo people may have moved into the American southwest, finding new homes and farmlands in the river drainages of Arizona, New Mexico and northern Mexico.
In about 1200, Shoshonean speaking peoples entered Utah territory from the west. They may have originated in southern California and moved into the desert environment due to population pressure along the coast. They were an upland people with a hunting and gathering lifestyle utilizing roots and seeds, including the pinyon nut. They were also skillful fishermen, created pottery and raised some crops. When they first arrived in Utah, they lived as small family groups with little tribal organization. Four main Shoshonean peoples inhabited Utah country. The Shoshone in the north and northeast, the Gosiutes in the northwest, the Utes in the central and eastern parts of the region and the Southern Paiutes in the southwest. Initially, there seems to have been very little conflict between these groups.
In the early 16th century, the San Juan River basin in Utah's southeast also saw a new people, the Díne or Navajo, part of a greater group of plains Athabaskan speakers moved into the Southwest from the Great Plains. In addition to the Navajo, this language group contained people that were later known as Apaches, including the Lipan, Jicarilla, and Mescalero Apaches.
Athabaskans were a hunting people who initially followed the bison, and were identified in 16th-century Spanish accounts as "dog nomads". The Athabaskans expanded their range throughout the 17th century, occupying areas the Pueblo peoples had abandoned during prior centuries. The Spanish first specifically mention the "Apachu de Nabajo" (Navaho) in the 1620s, referring to the people in the Chama valley region east of the San Juan River, and north west of Santa Fe. By the 1640s, the term Navaho was applied to these same people. Although the Navajo newcomers established a generally peaceful trading and cultural exchange with the some modern Pueblo peoples to the south, they experienced intermittent warfare with the Shoshonean peoples, particularly the Utes in eastern Utah and western Colorado.
At the time of European expansion, beginning with Spanish explorers traveling from Mexico, five distinct native peoples occupied territory within the Utah area: the Northern Shoshone, the Goshute, the Ute, the Paiute and the Navajo.
The Spanish explorer Francisco Vázquez de Coronado may have crossed into what is now southern Utah in 1540, when he was seeking the legendary Cíbola.
A group led by two Spanish Catholic priests—sometimes called the Domínguez–Escalante expedition—left Santa Fe in 1776, hoping to find a route to the California coast. The expedition traveled as far north as Utah Lake and encountered the native residents. All of what is now Utah was claimed by the Spanish Empire from the 1500s to 1821 as part of New Spain (later as the province Alta California); and subsequently claimed by Mexico from 1821 to 1848. However, Spain and Mexico had little permanent presence in, or control of, the region.
Fur trappers (also known as mountain men) including Jim Bridger, explored some regions of Utah in the early 19th century. The city of Provo was named for one such man, Étienne Provost, who visited the area in 1825. The city of Ogden, Utah is named for a brigade leader of the Hudson's Bay Company, Peter Skene Ogden who trapped in the Weber Valley. In 1846, a year before the arrival of members from the Church of Jesus Christ of latter-day Saints, the ill-fated Donner Party crossed through the Salt Lake valley late in the season, deciding not to stay the winter there but to continue forward to California, and beyond.
Members of the Church of Jesus Christ of Latter-day Saints, commonly known as Mormon pioneers, first came to the Salt Lake Valley on July 24, 1847. At the time, the U.S. had already captured the Mexican territories of Alta California and New Mexico in the Mexican–American War and planned to keep them, but those territories, including the future state of Utah, officially became United States territory upon the signing of the Treaty of Guadalupe Hidalgo, February 2, 1848. The treaty was ratified by the United States Senate on March 10, 1848.
Upon arrival in the Salt Lake Valley, the Mormon pioneers found no permanent settlement of Indians. Other areas along the Wasatch Range were occupied at the time of settlement by the Northwestern Shoshone and adjacent areas by other bands of Shoshone such as the Gosiute. The Northwestern Shoshone lived in the valleys on the eastern shore of Great Salt Lake and in adjacent mountain valleys. Some years after arriving in the Salt Lake Valley Mormons, who went on to colonize many other areas of what is now Utah, were petitioned by Indians for recompense for land taken. The response of Heber C. Kimball, first counselor to Brigham Young, was that the land belonged to "our Father in Heaven and we expect to plow and plant it." A 1945 Supreme Court decision found that the land had been treated by the United States as public domain; no aboriginal title by the Northwestern Shoshone had been recognized by the United States or extinguished by treaty with the United States.
Upon arriving in the Salt Lake Valley, the Mormons had to make a place to live. They created irrigation systems, laid out farms, built houses, churches, and schools. Access to water was crucially important. Almost immediately, Brigham Young set out to identify and claim additional community sites. While it was difficult to find large areas in the Great Basin where water sources were dependable and growing seasons long enough to raise vitally important subsistence crops, satellite communities began to be formed.
Shortly after the first company arrived in the Salt Lake Valley in 1847, the community of Bountiful was settled to the north. In 1848, settlers moved into lands purchased from trapper Miles Goodyear in present-day Ogden. In 1849, Tooele and Provo were founded. Also that year, at the invitation of Ute chief Wakara, settlers moved into the Sanpete Valley in central Utah to establish the community of Manti. Fillmore, Utah, intended to be the capital of the new territory, was established in 1851. In 1855, missionary efforts aimed at western native cultures led to outposts in Fort Lemhi, Idaho, Las Vegas, Nevada and Elk Mountain in east-central Utah.
The experiences of returning members of the Mormon Battalion were also important in establishing new communities. On their journey west, the Mormon soldiers had identified dependable rivers and fertile river valleys in Colorado, Arizona and southern California. In addition, as the men traveled to rejoin their families in the Salt Lake Valley, they moved through southern Nevada and the eastern segments of southern Utah. Jefferson Hunt, a senior Mormon officer of the Battalion, actively searched for settlement sites, minerals, and other resources. His report encouraged 1851 settlement efforts in Iron County, near present-day Cedar City. These southern explorations eventually led to Mormon settlements in St. George, Utah, Las Vegas and San Bernardino, California, as well as communities in southern Arizona.
Prior to establishment of the Oregon and California trails and Mormon settlement, Indians native to the Salt Lake Valley and adjacent areas lived by hunting buffalo and other game, but also gathered grass seed from the bountiful grass of the area as well as roots such as those of the Indian Camas. By the time of settlement, indeed before 1840, the buffalo were gone from the valley, but hunting by settlers and grazing of cattle severely impacted the Indians in the area, and as settlement expanded into nearby river valleys and oases, indigenous tribes experienced increasing difficulty in gathering sufficient food. Brigham Young's counsel was to feed the hungry tribes, and that was done, but it was often not enough. These tensions formed the background to the Bear River massacre committed by California Militia stationed in Salt Lake City during the Civil War. The site of the massacre is just inside Preston, Idaho, but was generally thought to be within Utah at the time.
Statehood was petitioned for in 1849-50 using the name Deseret. The proposed State of Deseret would have been quite large, encompassing all of what is now Utah, and portions of Colorado, Idaho, Nevada, Wyoming, Arizona, Oregon, New Mexico and California. The name of Deseret was favored by the LDS leader Brigham Young as a symbol of industry and was derived from a reference in the Book of Mormon. The petition was rejected by Congress and Utah did not become a state until 1896, following the Utah Constitutional Convention of 1895.
In 1850, the Utah Territory was created with the Compromise of 1850, and Fillmore (named after President Fillmore) was designated the capital. In 1856, Salt Lake City replaced Fillmore as the territorial capital.
The first group of pioneers brought African slaves with them, making Utah the only place in the western United States to have African slavery. Three slaves, Green Flake, Hark Lay, and Oscar Crosby, came west with this first group in 1847. The settlers also began to purchase Indian slaves in the well-established Indian slave trade, as well as enslaving Indian prisoners of war. In 1850, 26 slaves were counted in Salt Lake County. Slavery didn't become officially recognized until 1852, when the Act in Relation to Service and the Act for the relief of Indian Slaves and Prisoners were passed. Slavery was repealed on June 19, 1862, when Congress prohibited slavery in all US territories.
Disputes between the Mormon inhabitants and the federal government intensified after the Church of Jesus Christ of Latter-day Saints' practice of polygamy became known. The polygamous practices of the Mormons, which were made public in 1854, would be one of the major reasons Utah was denied statehood until almost 50 years after the Mormons had entered the area.
After news of their polygamous practices spread, the members of the LDS Church were quickly viewed by some as un-American and rebellious. In 1857, after news of a possible rebellion spread, President James Buchanan sent troops on the Utah expedition to quell the growing unrest and to replace Brigham Young as territorial governor with Alfred Cumming. The expedition was also known as the Utah War.
As fear of invasion grew, Mormon settlers had convinced some Paiute Indians to aid in a Mormon-led attack on 120 immigrants from Arkansas under the guise of Indian aggression. The murder of these settlers became known as the Mountain Meadows massacre. The Mormon leadership had adopted a defensive posture that led to a ban on the selling of grain to outsiders in preparation for an impending war. This chafed pioneers traveling through the region, who were unable to purchase badly needed supplies. A disagreement between some of the Arkansas pioneers and the Mormons in Cedar City led to the secret planning of the massacre by a few Mormon leaders in the area. Some scholars debate the involvement of Brigham Young. Only one man, John D. Lee, was ever convicted of the murders, and he was executed at the massacre site.
Express riders had brought the news 1,000 miles from the Missouri River settlements to Salt Lake City within about two weeks of the army's beginning to march west. Fearing the worst as 2,500 troops (roughly 1/3rd of the army then) led by General Albert Sidney Johnston started west, Brigham Young ordered all residents of Salt Lake City and neighboring communities to prepare their homes for burning and evacuate southward to Utah Valley and southern Utah. Young also sent out a few units of the Nauvoo Legion (numbering roughly 8,000–10,000), to delay the army's advance. The majority he sent into the mountains to prepare defenses or south to prepare for a scorched earth retreat. Although some army wagon supply trains were captured and burned and herds of army horses and cattle run off no serious fighting occurred. Starting late and short on supplies, the United States Army camped during the bitter winter of 1857–58 near a burned out Fort Bridger in Wyoming. Through the negotiations between emissary Thomas L. Kane, Young, Cumming and Johnston, control of Utah territory was peacefully transferred to Cumming, who entered an eerily vacant Salt Lake City in the spring of 1858. By agreement with Young, Johnston established the army at Fort Floyd 40 miles away from Salt Lake City, to the southwest.
Salt Lake City was the last link of the First Transcontinental Telegraph, between Carson City, Nevada and Omaha, Nebraska completed in October 1861. Brigham Young, who had helped expedite construction, was among the first to send a message, along with Abraham Lincoln and other officials. Soon after the telegraph line was completed, the Deseret Telegraph Company built the Deseret line connecting the settlements in the territory with Salt Lake City and, by extension, the rest of the United States.
Because of the American Civil War, federal troops were pulled out of Utah Territory (and their fort auctioned off), leaving the territorial government in federal hands without army backing until General Patrick E. Connor arrived with the 3rd Regiment of California Volunteers in 1862. While in Utah, Connor and his troops soon became discontent with this assignment wanting to head to Virginia where the "real" fighting and glory was occurring. Connor established Fort Douglas just three miles (5 km) east of Salt Lake City and encouraged his bored and often idle soldiers to go out and explore for mineral deposits to bring more non-Mormons into the state. Minerals were discovered in Tooele County, and some miners began to come to the territory. Conner also solved the Shoshone Indian problem in Cache Valley Utah by luring the Shoshone into a midwinter confrontation on January 29, 1863. The armed conflict quickly turned into a rout, discipline among the soldiers broke down, and the Battle of Bear River is today usually referred to by historians as the Bear River Massacre. Between 200 and 400 Shoshone men, women and children were killed, as were 27 soldiers, with over 50 more soldiers wounded or suffering from frostbite.
Beginning in 1865, Utah's Black Hawk War developed into the deadliest conflict in the territory's history. Chief Antonga Black Hawk died in 1870, but fights continued to break out until additional federal troops were sent in to suppress the Ghost Dance of 1872. The war is unique among Indian Wars because it was a three-way conflict, with mounted Timpanogos Utes led by Antonga Black Hawk fighting federal and Utah local militia.
On May 10, 1869, the First transcontinental railroad was completed at Promontory Summit, north of the Great Salt Lake. The railroad brought increasing numbers of people into the state, and several influential businessmen made fortunes in the territory.
Main article: Latter Day Saint polygamy in the late-19th century
During the 1870s and 1880s, federal laws were passed and federal marshals assigned to enforce the laws against polygamy. In the 1890 Manifesto, the LDS Church leadership dropped its approval of polygamy citing divine revelation. When Utah applied for statehood again in 1895, it was accepted. Statehood was officially granted on January 4, 1896.
The Mormon issue made the situation for women the topic of nationwide controversy. In 1870 the Utah Territory, controlled by Mormons, gave women the right to vote. However, in 1887, Congress disenfranchised Utah women with the Edmunds–Tucker Act. In 1867–96, eastern activists promoted women's suffrage in Utah as an experiment, and as a way to eliminate polygamy. They were Presbyterians and other Protestants convinced that Mormonism was a non-Christian cult that grossly mistreated women. The Mormons promoted woman suffrage to counter the negative image of downtrodden Mormon women. With the 1890 Manifesto clearing the way for statehood, in 1895 Utah adopted a constitution restoring the right of women's suffrage. Congress admitted Utah as a state with that constitution in 1896.
Though less numerous than other intermountain states at the time, several lynching murders for alleged misdeeds occurred in Utah territory at the hand of vigilantes. Those documented include the following, with their ethnicity or national origin noted in parentheses if it was provided in the source:
William Torrington in Carson City (then a part of Utah territory), 1859
Thomas Coleman (Black man) in Salt Lake City, 1866
3 unidentified men at Wahsatch, winter of 1868
A Black man in Uintah, 1869
Charles A. Benson in Logan, 1873
Ah Sing (Chinese man) in Corinne, 1874
Thomas Forrest in St. George, 1880
William Harvey (Black man) in Salt Lake City, 1883
John Murphy in Park City, 1883
George Segal (Japanese man) in Ogden, 1884
Joseph Fisher in Eureka, 1886
Robert Marshall (Black man) in Castle Gate, 1925
Other lynchings in Utah territory include multiple instances of mass murder of Native American children, women, and men by White settlers including the Battle Creek massacre (1849), Provo River Massacre (1850), Nephi massacre (1853), and Circleville Massacre (1866).
Beginning in the early 20th century, with the establishment of such national parks as Bryce Canyon National Park and Zion National Park, Utah began to become known for its natural beauty. Southern Utah became a popular filming spot for arid, rugged scenes, and such natural landmarks as Delicate Arch and "the Mittens" of Monument Valley are instantly recognizable to most national residents. During the 1950s, 1960s, and 1970s, with the construction of the Interstate highway system, accessibility to the southern scenic areas was made easier.
Beginning in 1939, with the establishment of Alta Ski Area, Utah has become world-renowned for its skiing. The dry, powdery snow of the Wasatch Range is considered some of the best skiing in the world. Salt Lake City won the bid for the 2002 Winter Olympics in 1995, and this has served as a great boost to the economy. The ski resorts have increased in popularity, and many of the Olympic venues scattered across the Wasatch Front continue to be used for sporting events. This also spurred the development of the light-rail system in the Salt Lake Valley, known as TRAX, and the re-construction of the freeway system around the city.
During the late 20th century, the state grew quickly. In the 1970s, growth was phenomenal in the suburbs. Sandy was one of the fastest-growing cities in the country at that time, and West Valley City is the state's 2nd most populous city. Today, many areas of Utah are seeing phenomenal growth. Northern Davis, southern and western Salt Lake, Summit, eastern Tooele, Utah, Wasatch, and Washington counties are all growing very quickly. Transportation and urbanization are major issues in politics as development consumes agricultural land and wilderness areas.
In 2012, the State of Utah passed the Utah Transfer of Public Lands Act in an attempt to gain control over a substantial portion of federal land in the state from the federal government, based on language in the Utah Enabling Act of 1894. The State does not intend to use force or assert control by limiting access in an attempt to control the disputed lands, but does intend to use a multi-step process of education, negotiation, legislation, and if necessary, litigation as part of its multi-year effort to gain state or private control over the lands after 2014.
Utah families, like most Americans everywhere, did their utmost to assist in the war effort. Tires, meat, butter, sugar, fats, oils, coffee, shoes, boots, gasoline, canned fruits, vegetables, and soups were rationed on a national basis. The school day was shortened and bus routes were reduced to limit the number of resources used stateside and increase what could be sent to soldiers.
Geneva Steel was built to increase the steel production for America during World War II. President Franklin D. Roosevelt had proposed opening a steel mill in Utah in 1936, but the idea was shelved after a couple of months. After the attack on Pearl Harbor, the United States entered the war and the steel plant was put into progress. In April 1944, Geneva shipped its first order, which consisted of over 600 tons of steel plate. Geneva Steel also brought thousands of job opportunities to Utah. The positions were hard to fill as many of Utah's men were overseas fighting. Women began working, filling 25 percent of the jobs.
As a result of Utah's and Geneva Steels contribution during the war, several Liberty Ships were named in honor of Utah including the USS Joseph Smith, USS Brigham Young, USS Provo, and the USS Peter Skene Ogden.
One of the sectors of the beachhead of Normandy Landings was codenamed Utah Beach, and the amphibious landings at the beach were undertaken by United States Army troops.
It is estimated that 1,450 soldiers from Utah were killed in the war.

"Has joy any survival value in the operations of evolution? I suspect that it does; I suspect that the morose and fearful are doomed to quick extinction. Where there is no joy there can be no courage; and without courage all other virtues are useless."

Jenny Lake, at the base of the Grand Tetons in Wyoming--the kind of place where you could spend weeks and never lack for places to wander. I took this after a hike around to Hidden Falls, right before sunset. The colors changed considerably from the afternoon. I love the colors and gentle painting of clouds across the sky. It's hard to be unhappy in such a place. I always feel so alive during these adventures.
. . . To receive the full value of joy, you must have someone to share it with
~ Mark Twain as quoted in the 2006 edition of The Joy of Cooking.
"That which thy fathers have bequeathed to thee, earn it anew if thou wouldst possess it"
~ Goethe: Faust as quoted in the 1975 edition of the Joy of Cooking.
The June selection for my Page 233 Cookbook Project is a triple treat because I have three editions of The Joy of Cooking by Irma Rombauer. In the 1946 edition, she writes in the Foreword, "Although I have been modernized by life and my children, my roots are Victorian. This book reflects my life. It once was merely a private record of what the family wanted, of what friends recommended and of dishes made familiar by foreign travel and given an acceptable Americanization." She includes a Preface to the 1943 Edition, "At the request of my children, who were leaving home, I began a record of 'what Mother used to make.' They thought, correctly that the work involved would help me tide over a period of loneliness."
It is refreshing to see things from her perspective. Especially these days. Someone who during the darkest times in her life became a light for so many others. It makes me happy that her family has carried on the tradition with subsequent editions.
The editions I have are from 1946, 1975 and 2006. I bought the 1975 edition back in the 80's because it had a good recipe for Cream Cheese Cookies. The 1946 edition came from my Mom's things. It was probably one she picked up at an estate sale and it has some additional ephemera treasures someone included. The 2006 edition, I added to my collection then.
From the 1946 edition, I chose Fish Cooked in Parchment Paper. I used a Striped Sea Bass. It was simple to make and it came out nicely.
From the 1975 edition, I chose Fish Timbale. Timbale means thimble. The recipe calls for the custard to be put in a 9 inch mold. I used two smaller ones instead. Although the Timbale was edible, it unfortunately was not photo-worthy. I think I'll save my molds for Angel Food cakes :-)
From the 2006 edition, I chose Stuffed Pears. Those came out heavenly! They can be served warm or cold.
There's another kind of Timbale.

The town of Southam in Warwickshire minted its own coins in mediaeval times because local people found ordinary coins too high in value for everyday use. In the English Civil War Charles I used Southam's mint to make new coins to pay his troops. Built in the early 16th century the coin mint house is now a pub – unsurprisingly called ‘the Olde Mint’. The grooves in the stone doorway are said to be the result of soldiers sharpening their swords

High Dynamic Range (HDR)
High-dynamic-range imaging (HDRI) is a high dynamic range (HDR) technique used in imaging and photography to reproduce a greater dynamic range of luminosity than is possible with standard digital imaging or photographic techniques. The aim is to present a similar range of luminance to that experienced through the human visual system. The human eye, through adaptation of the iris and other methods, adjusts constantly to adapt to a broad range of luminance present in the environment. The brain continuously interprets this information so that a viewer can see in a wide range of light conditions.
HDR images can represent a greater range of luminance levels than can be achieved using more 'traditional' methods, such as many real-world scenes containing very bright, direct sunlight to extreme shade, or very faint nebulae. This is often achieved by capturing and then combining several different, narrower range, exposures of the same subject matter. Non-HDR cameras take photographs with a limited exposure range, referred to as LDR, resulting in the loss of detail in highlights or shadows.
The two primary types of HDR images are computer renderings and images resulting from merging multiple low-dynamic-range (LDR) or standard-dynamic-range (SDR) photographs. HDR images can also be acquired using special image sensors, such as an oversampled binary image sensor.
Due to the limitations of printing and display contrast, the extended luminosity range of an HDR image has to be compressed to be made visible. The method of rendering an HDR image to a standard monitor or printing device is called tone mapping. This method reduces the overall contrast of an HDR image to facilitate display on devices or printouts with lower dynamic range, and can be applied to produce images with preserved local contrast (or exaggerated for artistic effect).
In photography, dynamic range is measured in exposure value (EV) differences (known as stops). An increase of one EV, or 'one stop', represents a doubling of the amount of light. Conversely, a decrease of one EV represents a halving of the amount of light. Therefore, revealing detail in the darkest of shadows requires high exposures, while preserving detail in very bright situations requires very low exposures. Most cameras cannot provide this range of exposure values within a single exposure, due to their low dynamic range. High-dynamic-range photographs are generally achieved by capturing multiple standard-exposure images, often using exposure bracketing, and then later merging them into a single HDR image, usually within a photo manipulation program). Digital images are often encoded in a camera's raw image format, because 8-bit JPEG encoding does not offer a wide enough range of values to allow fine transitions (and regarding HDR, later introduces undesirable effects due to lossy compression).
Any camera that allows manual exposure control can make images for HDR work, although one equipped with auto exposure bracketing (AEB) is far better suited. Images from film cameras are less suitable as they often must first be digitized, so that they can later be processed using software HDR methods.
In most imaging devices, the degree of exposure to light applied to the active element (be it film or CCD) can be altered in one of two ways: by either increasing/decreasing the size of the aperture or by increasing/decreasing the time of each exposure. Exposure variation in an HDR set is only done by altering the exposure time and not the aperture size; this is because altering the aperture size also affects the depth of field and so the resultant multiple images would be quite different, preventing their final combination into a single HDR image.
An important limitation for HDR photography is that any movement between successive images will impede or prevent success in combining them afterwards. Also, as one must create several images (often three or five and sometimes more) to obtain the desired luminance range, such a full 'set' of images takes extra time. HDR photographers have developed calculation methods and techniques to partially overcome these problems, but the use of a sturdy tripod is, at least, advised.
Some cameras have an auto exposure bracketing (AEB) feature with a far greater dynamic range than others, from the 3 EV of the Canon EOS 40D, to the 18 EV of the Canon EOS-1D Mark II. As the popularity of this imaging method grows, several camera manufactures are now offering built-in HDR features. For example, the Pentax K-7 DSLR has an HDR mode that captures an HDR image and outputs (only) a tone mapped JPEG file. The Canon PowerShot G12, Canon PowerShot S95 and Canon PowerShot S100 offer similar features in a smaller format.. Nikon's approach is called 'Active D-Lighting' which applies exposure compensation and tone mapping to the image as it comes from the sensor, with the accent being on retaing a realistic effect . Some smartphones provide HDR modes, and most mobile platforms have apps that provide HDR picture taking.
Camera characteristics such as gamma curves, sensor resolution, noise, photometric calibration and color calibration affect resulting high-dynamic-range images.
Color film negatives and slides consist of multiple film layers that respond to light differently. As a consequence, transparent originals (especially positive slides) feature a very high dynamic range
Tone mapping
Tone mapping reduces the dynamic range, or contrast ratio, of an entire image while retaining localized contrast. Although it is a distinct operation, tone mapping is often applied to HDRI files by the same software package.
Several software applications are available on the PC, Mac and Linux platforms for producing HDR files and tone mapped images. Notable titles include
Adobe Photoshop
Aurora HDR
Dynamic Photo HDR
HDR Efex Pro
HDR PhotoStudio

Information stored in high-dynamic-range images typically corresponds to the physical values of luminance or radiance that can be observed in the real world. This is different from traditional digital images, which represent colors as they should appear on a monitor or a paper print. Therefore, HDR image formats are often called scene-referred, in contrast to traditional digital images, which are device-referred or output-referred. Furthermore, traditional images are usually encoded for the human visual system (maximizing the visual information stored in the fixed number of bits), which is usually called gamma encoding or gamma correction. The values stored for HDR images are often gamma compressed (power law) or logarithmically encoded, or floating-point linear values, since fixed-point linear encodings are increasingly inefficient over higher dynamic ranges.
HDR images often don't use fixed ranges per color channel—other than traditional images—to represent many more colors over a much wider dynamic range. For that purpose, they don't use integer values to represent the single color channels (e.g., 0-255 in an 8 bit per pixel interval for red, green and blue) but instead use a floating point representation. Common are 16-bit (half precision) or 32-bit floating point numbers to represent HDR pixels. However, when the appropriate transfer function is used, HDR pixels for some applications can be represented with a color depth that has as few as 10–12 bits for luminance and 8 bits for chrominance without introducing any visible quantization artifacts.
History of HDR photography
The idea of using several exposures to adequately reproduce a too-extreme range of luminance was pioneered as early as the 1850s by Gustave Le Gray to render seascapes showing both the sky and the sea. Such rendering was impossible at the time using standard methods, as the luminosity range was too extreme. Le Gray used one negative for the sky, and another one with a longer exposure for the sea, and combined the two into one picture in positive.
Mid 20th century
Manual tone mapping was accomplished by dodging and burning – selectively increasing or decreasing the exposure of regions of the photograph to yield better tonality reproduction. This was effective because the dynamic range of the negative is significantly higher than would be available on the finished positive paper print when that is exposed via the negative in a uniform manner. An excellent example is the photograph Schweitzer at the Lamp by W. Eugene Smith, from his 1954 photo essay A Man of Mercy on Dr. Albert Schweitzer and his humanitarian work in French Equatorial Africa. The image took 5 days to reproduce the tonal range of the scene, which ranges from a bright lamp (relative to the scene) to a dark shadow.
Ansel Adams elevated dodging and burning to an art form. Many of his famous prints were manipulated in the darkroom with these two methods. Adams wrote a comprehensive book on producing prints called The Print, which prominently features dodging and burning, in the context of his Zone System.
With the advent of color photography, tone mapping in the darkroom was no longer possible due to the specific timing needed during the developing process of color film. Photographers looked to film manufacturers to design new film stocks with improved response, or continued to shoot in black and white to use tone mapping methods.
Color film capable of directly recording high-dynamic-range images was developed by Charles Wyckoff and EG&G "in the course of a contract with the Department of the Air Force". This XR film had three emulsion layers, an upper layer having an ASA speed rating of 400, a middle layer with an intermediate rating, and a lower layer with an ASA rating of 0.004. The film was processed in a manner similar to color films, and each layer produced a different color. The dynamic range of this extended range film has been estimated as 1:108. It has been used to photograph nuclear explosions, for astronomical photography, for spectrographic research, and for medical imaging. Wyckoff's detailed pictures of nuclear explosions appeared on the cover of Life magazine in the mid-1950s.
Late 20th century
Georges Cornuéjols and licensees of his patents (Brdi, Hymatom) introduced the principle of HDR video image, in 1986, by interposing a matricial LCD screen in front of the camera's image sensor, increasing the sensors dynamic by five stops. The concept of neighborhood tone mapping was applied to video cameras by a group from the Technion in Israel led by Dr. Oliver Hilsenrath and Prof. Y.Y.Zeevi who filed for a patent on this concept in 1988.
In February and April 1990, Georges Cornuéjols introduced the first real-time HDR camera that combined two images captured by a sensor3435 or simultaneously3637 by two sensors of the camera. This process is known as bracketing used for a video stream.
In 1991, the first commercial video camera was introduced that performed real-time capturing of multiple images with different exposures, and producing an HDR video image, by Hymatom, licensee of Georges Cornuéjols.
Also in 1991, Georges Cornuéjols introduced the HDR+ image principle by non-linear accumulation of images to increase the sensitivity of the camera: for low-light environments, several successive images are accumulated, thus increasing the signal to noise ratio.
In 1993, another commercial medical camera producing an HDR video image, by the Technion.
Modern HDR imaging uses a completely different approach, based on making a high-dynamic-range luminance or light map using only global image operations (across the entire image), and then tone mapping the result. Global HDR was first introduced in 19931 resulting in a mathematical theory of differently exposed pictures of the same subject matter that was published in 1995 by Steve Mann and Rosalind Picard.
On October 28, 1998, Ben Sarao created one of the first nighttime HDR+G (High Dynamic Range + Graphic image)of STS-95 on the launch pad at NASA's Kennedy Space Center. It consisted of four film images of the shuttle at night that were digitally composited with additional digital graphic elements. The image was first exhibited at NASA Headquarters Great Hall, Washington DC in 1999 and then published in Hasselblad Forum, Issue 3 1993, Volume 35 ISSN 0282-5449.
The advent of consumer digital cameras produced a new demand for HDR imaging to improve the light response of digital camera sensors, which had a much smaller dynamic range than film. Steve Mann developed and patented the global-HDR method for producing digital images having extended dynamic range at the MIT Media Laboratory. Mann's method involved a two-step procedure: (1) generate one floating point image array by global-only image operations (operations that affect all pixels identically, without regard to their local neighborhoods); and then (2) convert this image array, using local neighborhood processing (tone-remapping, etc.), into an HDR image. The image array generated by the first step of Mann's process is called a lightspace image, lightspace picture, or radiance map. Another benefit of global-HDR imaging is that it provides access to the intermediate light or radiance map, which has been used for computer vision, and other image processing operations.
21st century
In 2005, Adobe Systems introduced several new features in Photoshop CS2 including Merge to HDR, 32 bit floating point image support, and HDR tone mapping.
On June 30, 2016, Microsoft added support for the digital compositing of HDR images to Windows 10 using the Universal Windows Platform.
HDR sensors
Modern CMOS image sensors can often capture a high dynamic range from a single exposure. The wide dynamic range of the captured image is non-linearly compressed into a smaller dynamic range electronic representation. However, with proper processing, the information from a single exposure can be used to create an HDR image.
Such HDR imaging is used in extreme dynamic range applications like welding or automotive work. Some other cameras designed for use in security applications can automatically provide two or more images for each frame, with changing exposure. For example, a sensor for 30fps video will give out 60fps with the odd frames at a short exposure time and the even frames at a longer exposure time. Some of the sensor may even combine the two images on-chip so that a wider dynamic range without in-pixel compression is directly available to the user for display or processing.

Infrared Photography
In infrared photography, the film or image sensor used is sensitive to infrared light. The part of the spectrum used is referred to as near-infrared to distinguish it from far-infrared, which is the domain of thermal imaging. Wavelengths used for photography range from about 700 nm to about 900 nm. Film is usually sensitive to visible light too, so an infrared-passing filter is used; this lets infrared (IR) light pass through to the camera, but blocks all or most of the visible light spectrum (the filter thus looks black or deep red). ("Infrared filter" may refer either to this type of filter or to one that blocks infrared but passes other wavelengths.)
When these filters are used together with infrared-sensitive film or sensors, "in-camera effects" can be obtained; false-color or black-and-white images with a dreamlike or sometimes lurid appearance known as the "Wood Effect," an effect mainly caused by foliage (such as tree leaves and grass) strongly reflecting in the same way visible light is reflected from snow. There is a small contribution from chlorophyll fluorescence, but this is marginal and is not the real cause of the brightness seen in infrared photographs. The effect is named after the infrared photography pioneer Robert W. Wood, and not after the material wood, which does not strongly reflect infrared.
The other attributes of infrared photographs include very dark skies and penetration of atmospheric haze, caused by reduced Rayleigh scattering and Mie scattering, respectively, compared to visible light. The dark skies, in turn, result in less infrared light in shadows and dark reflections of those skies from water, and clouds will stand out strongly. These wavelengths also penetrate a few millimeters into skin and give a milky look to portraits, although eyes often look black.
Until the early 20th century, infrared photography was not possible because silver halide emulsions are not sensitive to longer wavelengths than that of blue light (and to a lesser extent, green light) without the addition of a dye to act as a color sensitizer. The first infrared photographs (as distinct from spectrographs) to be published appeared in the February 1910 edition of The Century Magazine and in the October 1910 edition of the Royal Photographic Society Journal to illustrate papers by Robert W. Wood, who discovered the unusual effects that now bear his name. The RPS co-ordinated events to celebrate the centenary of this event in 2010. Wood's photographs were taken on experimental film that required very long exposures; thus, most of his work focused on landscapes. A further set of infrared landscapes taken by Wood in Italy in 1911 used plates provided for him by CEK Mees at Wratten & Wainwright. Mees also took a few infrared photographs in Portugal in 1910, which are now in the Kodak archives.
Infrared-sensitive photographic plates were developed in the United States during World War I for spectroscopic analysis, and infrared sensitizing dyes were investigated for improved haze penetration in aerial photography. After 1930, new emulsions from Kodak and other manufacturers became useful to infrared astronomy.
Infrared photography became popular with photography enthusiasts in the 1930s when suitable film was introduced commercially. The Times regularly published landscape and aerial photographs taken by their staff photographers using Ilford infrared film. By 1937 33 kinds of infrared film were available from five manufacturers including Agfa, Kodak and Ilford. Infrared movie film was also available and was used to create day-for-night effects in motion pictures, a notable example being the pseudo-night aerial sequences in the James Cagney/Bette Davis movie The Bride Came COD.
False-color infrared photography became widely practiced with the introduction of Kodak Ektachrome Infrared Aero Film and Ektachrome Infrared EIR. The first version of this, known as Kodacolor Aero-Reversal-Film, was developed by Clark and others at the Kodak for camouflage detection in the 1940s. The film became more widely available in 35mm form in the 1960s but KODAK AEROCHROME III Infrared Film 1443 has been discontinued.
Infrared photography became popular with a number of 1960s recording artists, because of the unusual results; Jimi Hendrix, Donovan, Frank and a slow shutter speed without focus compensation, however wider apertures like f/2.0 can produce sharp photos only if the lens is meticulously refocused to the infrared index mark, and only if this index mark is the correct one for the filter and film in use. However, it should be noted that diffraction effects inside a camera are greater at infrared wavelengths so that stopping down the lens too far may actually reduce sharpness.
Most apochromatic ('APO') lenses do not have an Infrared index mark and do not need to be refocused for the infrared spectrum because they are already optically corrected into the near-infrared spectrum. Catadioptric lenses do not often require this adjustment because their mirror containing elements do not suffer from chromatic aberration and so the overall aberration is comparably less. Catadioptric lenses do, of course, still contain lenses, and these lenses do still have a dispersive property.
Infrared black-and-white films require special development times but development is usually achieved with standard black-and-white film developers and chemicals (like D-76). Kodak HIE film has a polyester film base that is very stable but extremely easy to scratch, therefore special care must be used in the handling of Kodak HIE throughout the development and printing/scanning process to avoid damage to the film. The Kodak HIE film was sensitive to 900 nm.
As of November 2, 2007, "KODAK is preannouncing the discontinuance" of HIE Infrared 35 mm film stating the reasons that, "Demand for these products has been declining significantly in recent years, and it is no longer practical to continue to manufacture given the low volume, the age of the product formulations and the complexity of the processes involved." At the time of this notice, HIE Infrared 135-36 was available at a street price of around $12.00 a roll at US mail order outlets.
Arguably the greatest obstacle to infrared film photography has been the increasing difficulty of obtaining infrared-sensitive film. However, despite the discontinuance of HIE, other newer infrared sensitive emulsions from EFKE, ROLLEI, and ILFORD are still available, but these formulations have differing sensitivity and specifications from the venerable KODAK HIE that has been around for at least two decades. Some of these infrared films are available in 120 and larger formats as well as 35 mm, which adds flexibility to their application. With the discontinuance of Kodak HIE, Efke's IR820 film has become the only IR film on the marketneeds update with good sensitivity beyond 750 nm, the Rollei film does extend beyond 750 nm but IR sensitivity falls off very rapidly.
Color infrared transparency films have three sensitized layers that, because of the way the dyes are coupled to these layers, reproduce infrared as red, red as green, and green as blue. All three layers are sensitive to blue so the film must be used with a yellow filter, since this will block blue light but allow the remaining colors to reach the film. The health of foliage can be determined from the relative strengths of green and infrared light reflected; this shows in color infrared as a shift from red (healthy) towards magenta (unhealthy). Early color infrared films were developed in the older E-4 process, but Kodak later manufactured a color transparency film that could be developed in standard E-6 chemistry, although more accurate results were obtained by developing using the AR-5 process. In general, color infrared does not need to be refocused to the infrared index mark on the lens.
In 2007 Kodak announced that production of the 35 mm version of their color infrared film (Ektachrome Professional Infrared/EIR) would cease as there was insufficient demand. Since 2011, all formats of color infrared film have been discontinued. Specifically, Aerochrome 1443 and SO-734.
There is no currently available digital camera that will produce the same results as Kodak color infrared film although the equivalent images can be produced by taking two exposures, one infrared and the other full-color, and combining in post-production. The color images produced by digital still cameras using infrared-pass filters are not equivalent to those produced on color infrared film. The colors result from varying amounts of infrared passing through the color filters on the photo sites, further amended by the Bayer filtering. While this makes such images unsuitable for the kind of applications for which the film was used, such as remote sensing of plant health, the resulting color tonality has proved popular artistically.
Color digital infrared, as part of full spectrum photography is gaining popularity. The ease of creating a softly colored photo with infrared characteristics has found interest among hobbyists and professionals.
In 2008, Los Angeles photographer, Dean Bennici started cutting and hand rolling Aerochrome color Infrared film. All Aerochrome medium and large format which exists today came directly from his lab. The trend in infrared photography continues to gain momentum with the success of photographer Richard Mosse and multiple users all around the world.
Digital camera sensors are inherently sensitive to infrared light, which would interfere with the normal photography by confusing the autofocus calculations or softening the image (because infrared light is focused differently from visible light), or oversaturating the red channel. Also, some clothing is transparent in the infrared, leading to unintended (at least to the manufacturer) uses of video cameras. Thus, to improve image quality and protect privacy, many digital cameras employ infrared blockers. Depending on the subject matter, infrared photography may not be practical with these cameras because the exposure times become overly long, often in the range of 30 seconds, creating noise and motion blur in the final image. However, for some subject matter the long exposure does not matter or the motion blur effects actually add to the image. Some lenses will also show a 'hot spot' in the centre of the image as their coatings are optimised for visible light and not for IR.
An alternative method of DSLR infrared photography is to remove the infrared blocker in front of the sensor and replace it with a filter that removes visible light. This filter is behind the mirror, so the camera can be used normally - handheld, normal shutter speeds, normal composition through the viewfinder, and focus, all work like a normal camera. Metering works but is not always accurate because of the difference between visible and infrared refraction. When the IR blocker is removed, many lenses which did display a hotspot cease to do so, and become perfectly usable for infrared photography. Additionally, because the red, green and blue micro-filters remain and have transmissions not only in their respective color but also in the infrared, enhanced infrared color may be recorded.
Since the Bayer filters in most digital cameras absorb a significant fraction of the infrared light, these cameras are sometimes not very sensitive as infrared cameras and can sometimes produce false colors in the images. An alternative approach is to use a Foveon X3 sensor, which does not have absorptive filters on it; the Sigma SD10 DSLR has a removable IR blocking filter and dust protector, which can be simply omitted or replaced by a deep red or complete visible light blocking filter. The Sigma SD14 has an IR/UV blocking filter that can be removed/installed without tools. The result is a very sensitive digital IR camera.
While it is common to use a filter that blocks almost all visible light, the wavelength sensitivity of a digital camera without internal infrared blocking is such that a variety of artistic results can be obtained with more conventional filtration. For example, a very dark neutral density filter can be used (such as the Hoya ND400) which passes a very small amount of visible light compared to the near-infrared it allows through. Wider filtration permits an SLR viewfinder to be used and also passes more varied color information to the sensor without necessarily reducing the Wood effect. Wider filtration is however likely to reduce other infrared artefacts such as haze penetration and darkened skies. This technique mirrors the methods used by infrared film photographers where black-and-white infrared film was often used with a deep red filter rather than a visually opaque one.
Another common technique with near-infrared filters is to swap blue and red channels in software (e.g. photoshop) which retains much of the characteristic 'white foliage' while rendering skies a glorious blue.
Several Sony cameras had the so-called Night Shot facility, which physically moves the blocking filter away from the light path, which makes the cameras very sensitive to infrared light. Soon after its development, this facility was 'restricted' by Sony to make it difficult for people to take photos that saw through clothing. To do this the iris is opened fully and exposure duration is limited to long times of more than 1/30 second or so. It is possible to shoot infrared but neutral density filters must be used to reduce the camera's sensitivity and the long exposure times mean that care must be taken to avoid camera-shake artifacts.
Fuji have produced digital cameras for use in forensic criminology and medicine which have no infrared blocking filter. The first camera, designated the S3 PRO UVIR, also had extended ultraviolet sensitivity (digital sensors are usually less sensitive to UV than to IR). Optimum UV sensitivity requires special lenses, but ordinary lenses usually work well for IR. In 2007, FujiFilm introduced a new version of this camera, based on the Nikon D200/ FujiFilm S5 called the IS Pro, also able to take Nikon lenses. Fuji had earlier introduced a non-SLR infrared camera, the IS-1, a modified version of the FujiFilm FinePix S9100. Unlike the S3 PRO UVIR, the IS-1 does not offer UV sensitivity. FujiFilm restricts the sale of these cameras to professional users with their EULA specifically prohibiting "unethical photographic conduct".
Phase One digital camera backs can be ordered in an infrared modified form.
Remote sensing and thermographic cameras are sensitive to longer wavelengths of infrared (see Infrared spectrum#Commonly used sub-division scheme). They may be multispectral and use a variety of technologies which may not resemble common camera or filter designs. Cameras sensitive to longer infrared wavelengths including those used in infrared astronomy often require cooling to reduce thermally induced dark currents in the sensor (see Dark current (physics)). Lower cost uncooled thermographic digital cameras operate in the Long Wave infrared band (see Thermographic camera#Uncooled infrared detectors). These cameras are generally used for building inspection or preventative maintenance but can be used for artistic pursuits as well.
