            These   remarkable 19th century sepia-tinted pictures show the American West as   you have never seen it before - as it was charted for the first   time.The photos, by Timothy O'Sullivan, are the first ever taken of the   rocky and barren landscape. At the time federal government officials   were travelling across Arizona, Nevada, Utah and the rest of the west as   they sought to uncover the land's untapped natural resources.
  
            Breathtaking   landscape: A view across the Shoshone Falls, Snake River, Idaho in 1874   as it was caught on camera by photographer Timothy O'Sullivan during   Lt. George M. Wheeler's survey west of the One Hundredth Meridian that   lasted from 1871 to 1874. Approximately 45 feet higher than the Niagara   falls of the U.S and Canada, the Shoshone Falls are sometimes called the   'Niagara of the West'. Before mass migration and industrialisation of   the west, the Bannock and Shoshone Indians relied on the huge salmon   stocks of the falls as a source of food. And the John C. Fremont   Expedition of 1843, one of the first missions to encounter the falls   reported that salmon could be caught simply by throwing a spear into the   water, such was the stock
  
            Land   rising from the water: The Pyramid and Domes, a line of dome-shaped   tufa rocks in Pyramid Lake, Nevada photographed in 1867. Taken as part   of Clarence King's Geological Exploration of the Fortieth Parallel,   O'Sullivan's mesmerising pictures of the other-wordly rock formations at   Pyramid Lake committed the sacred native American Indian site to camera   for the first time
  
            Famous   photographer: Timothy O'Sullivan whose childhood and background are the   subject of debate among photographic scholar was of Irish ancestry. It   is known that as a teenager he worked in the studio of the legendary   19th century photographer Mathew Brady, who is seen as the father of   photo-journalism. A veteran of the American Civil War in its first year,   O'Sullivan turned his hand to photographing the horrors of war in   during the final three years of the conflict before setting out on his   cross-continental expeditions.
  Timothy   O'Sullivan, who used a box camera, worked with the Government teams as   they explored the land. He had earlier covered the U.S. Civil War and   was one of the most famous photographers of the 19th century.
  He   also took pictures of the Native American population for the first time   as a team of artists, photographers, scientists and soldiers explored   the land in the 1860s and 1870s.
  The   images of the landscape were remarkable - because the majority of   people at the time would not have known they were there or have ever had   a chance to see it for themselves.
  O'Sullivan died from tuberculosis at the age of 42 in 1882 - just years after the project had finished .
            He   carted a dark room wagon around the Wild West on horseback so that he   could develop his images. He spent seven years exploring the landscape   and thousands of pictures have survived from his travels.
   
The project was designed to attract settlers to the largely uninhabited region.
            O'Sullivan   used a primitive wet plate box camera which he would have to spend   several minutes setting up every time he wanted to take a photograph.
  He   would have to assemble the device on a tripod, coat a glass plate with   collodion - a flammable solution. The glass would then be put in a   holder before being inserted into a camera.
  After   a few seconds exposure, he would rush the plate to his dark room wagon   and cover it in chemicals to begin the development process.
  Considered one of the forerunners to Ansel Adams, Timothy O'Sullivan is a hero to other photographers.
            
'Most of the photographers sent to document the West's native   peoples and its geologic formations tried to make this strange new land   accessible, even picturesque,' said Keith McElroy a history of   photography professor in Tucson.
  'Not O'Sullivan. 
            'At   a time when Manifest Destiny demanded that Americans conquer the land,   he pictured a West that was forbidding and inhospitable. 
  'With an almost modern sensibility, he made humans and their works insignificant. 
            'His   photographs picture scenes, like a flimsy boat helpless against the   dark shadows of Black Canyon, or explorers almost swallowed up by the   crevices of Canyon de Chelly.'
  
            Native   Americans: The Pah-Ute (Paiute) Indian group, near Cedar, Utah in a   picture from 1872. Government officials were chartering the land for the   first time as part of Lt. George M. Wheeler's survey west of the One   Hundredth Meridian which O'Sullivan accompanied the Lieutenant on.   During this expedition O'Sullivan nearly drowned in the Truckee River   (which runs from Lake Tahoe to Pyramid Lake, located in northwestern   Nevada) when his boat got jammed against rocks. 
  
        Breathtaking:   Twin buttes stand near Green River City, Wyoming, photographed in 1872   four years after settlers made the river basin their home. Green River   and its distinctive twin rock formations that stand over the horizon was   supposed to the site of a division point for the Union Pacific   Railroad, but when the engineers arrived they were shocked to find that   the area had been settled and so had to move the railroad west 12 miles   to Bryan, Wyoming.
   
        19th   century housing: Members of Clarence King's Fortieth Parallel Survey   team explore the land near Oreana, Nevada, in 1867. Clarence King was a   25-year-old Yale graduate, who hired Irish tough guy O'Sullivan for his   Geological Exploration of the Fortieth Parallel. Funded by the War   Department, the plan was to survey the unexplored territory that lay   between the California Sierras and the Rockies, with a view toward   finding a good place to lay railroad tracks while also looking for   mining possibilities and assessing the level of Indian hostility in the   area.
   
        Incredible:   Tents can be seen (bottom, centre) at a point known as Camp Beauty   close to canyon walls in Canyon de Chelly National Monument, Arizona.   Photographed in 1873 and situated in northeastern Arizona, the area is   one of the longest continuously inhabited landscapes in North American   and holds preserved ruins of early indigenous people's such as The   Anasazi and Navajo.
   

            On   this rock I build a church: Old Mission Church, Zuni Pueblo, New Mexico   pictured in 1873 where the Zuni people of North have lived for   millennia. O'Sullivan was famous for not trying to romanticise the   native American plight or way of life in his photographs and instead of   asking them to wear tribal dress was happy to photograph them wearing   denim jeans.
   

            9.   Native Americans: Boat crew of the 'Picture' at Diamond Creek. Photo   shows photographer Timothy O'Sullivan, fourth from left, with fellow   members of the Wheeler survey and Native Americans, following ascent of   the Colorado River through the Black Canyon in 1871. O'Sullivans work   during Lt. George M. Wheeler's survey west of the One Hundredth Meridian   in Black Canyon has been called some of the greates photography of the   19th century and a clear inspiration for that other great American   photographer Ansel Adams.
   

            Landscape:   Browns Park, Colorado, as seen by Timothy O'Sullivan in 1872 as he   chartered the landscape for the first time. Historians have noted that   even though the photographer had become a more-than-experienced explorer   at this point, the ordeals of the Wheeler survey tested him to the   extremes of his endurance
   

            Rockies:   A man sits on a shore beside the Colorado River in Iceberg Canyon, on   the border of Mojave County, Arizona, and Clark County, Nevada in 1871   during the Wheeler expedition. Lieutenant Wheeler insisted that the team   explore the Colorado River by going upstream into the Grand   Canyon--apparently to beat a rival, who had first gone downriver in   1869. There was no particular scientific reason to do the trip   backward. 
   

            Timothy   O'Sullivan's darkroom wagon, pulled by four mules, entered the frame at   the right side of the photograph, reached the center of the image, and   abruptly U-turned, heading back out of the frame. Footprints leading   from the wagon toward the camera reveal the photographer's path. Made at   the Carson Sink in Nevada, this image of shifting sand dunes reveals   the patterns of tracks recently reconfigured by the wind. The wagon's   striking presence in this otherwise barren scene dramatises the   pioneering experience of exploration and discovery in the wide,   uncharted landscapes of the American West.
   

            Industrial   revolution: The mining town of Gold Hill, just south of Virginia City,   Nevada, in 1867 was town whose prosperity was preserved by mining a rare   silver ore called Comstock Lode. On the United States Geological   Exploration of the Fortieth Parallel, Clarence King insisted that his   men dress for dinner every evening and speak French, and O'Sullivan had   no difficulty fitting in.
   

            Early   rails: A wooden balanced incline used for gold mining, at the Illinois   Mine in the Pahranagat Mining District, Nevada in 1871. An ore car would   ride on parallel tracks connected to a pulley wheel at the top of   tracks. Because of his work in U.S Civil War of 1861 to 1865, the   organisers of the two geological surveys that he photographed knew that   O'Sullivan was made of stern stuff and therefore could cope with the   rigurs of life outdoors far from home
   

            Silver   mining: Here photographer Timothy O'Sullivan documents the actvities of   the Savage and the Gould and Curry mines in Virginia City, Nevada, in   1867 900ft underground, lit by an improvised flash -- a burning   magnesium wire, O'Sullivan photographed the miners in tunnels, shafts,   and lifts. During the winter of 1867-68, in Virginia City, Nevada, he   took the first underground mining pictures in America. Deep in mines   where temperatures reached 130 degrees, O'Sullivan took pictures by the   light of magnesium wire in difficult circumstances

            Portrait:   Native American (Paiute) men, women and children pose for a picture   near a tree. The picture is thought to have been taken in Cottonwood   Springs (Washoe County), Nevada, in 1875
   

            Natural U.S. landscape: The junction of Green and Yampah Canyons, in Utah, in 1872
             

            An   earlier visitor: Nearly 150 years ago, photographer O'Sullivan came   across this evidence of a visitor to the West that preceded his own   expedition by another 150 years - A Spanish inscription from 1726. This   close-up view of the inscription carved in the sandstone at Inscription   Rock (El Morro National Monument), New Mexico reads, in English: "By   this place passed Ensign Don Joseph de Payba Basconzelos, in the year in   which he held the Council of the Kingdom at his expense, on the 18th of   February, in the year 1726"
   
        Insight: Aboriginal life among the Navajo Indians. Near old Fort Defiance, New Mexico, in 1873
             

            Incredible backdrop: The Canyon of Lodore, Colorado, in 1872
             

            Settlement:   View of the White House, Ancestral Pueblo Native American (Anasazi)   ruins in Canyon de Chelly, Arizona, in 1873. The cliff dwellings were   built by the Anasazi more than 500 years earlier. At the bottom, men   stand and pose on cliff dwellings in a niche and on ruins on the canyon   floor. Climbing ropes connect the groups of men.
   

            Sailing away: The Nettie, an expedition boat on the Truckee River, western Nevada, in 1867
             

            Taking a dip: A man bathing in Pagosa Hot Spring, Colorado, in 1874
             

            A   man sits in a wooden boat with a mast on the edge of the Colorado River   in the Black Canyon, Mojave County, Arizona. At this time, photographer   Timothy O'Sullivan was working as a military photographer, for Lt.   George Montague Wheeler's U.S. Geographical Surveys West of the One   Hundredth Meridian. Photo taken in 1871, from an expedition camp,   looking upstream

        Shoshone   Falls, Idaho near present-day Twin Falls, Idaho, is 212 feet high, and   flows over a rim 1,000 feet wide. it is pictured in 1868
   
        Rocky:   The south side of Inscription Rock (now El Morro National Monument), in   New Mexico in 1873. The prominent feature stands near a small pool of   water, and has been a resting place for travellers for centuries. Since   at least the 17th century, natives, Europeans, and later American   pioneers carved names and messages into the rock face as they paused. In   1906, a law was passed, prohibiting further carving.
