Photographs Showing Landscapes, Geological, and Other Features, of Portions of the Western Territory of the United States, commonly known as Wheeler Survey, is a key collection of 19th-century survey photography. Created between 1871 and 1873 as part of the Geographical and Geological Explorations West of the 100th Meridian—a government-sponsored initiative led by Lieutenant George M. Wheeler—the project was produced collaboratively by Timothy H. O’Sullivan and William Bell. O’Sullivan contributed photographs from the 1871 and 1873 seasons, while Bell replaced him in 1872 when O’Sullivan joined another expedition. Together, their work documented the vast and rugged terrains of the American West, including Arizona, Nevada, Utah, and New Mexico, combining scientific inquiry with artistic expression to create a landmark visual record.
Emerging during a time of rapid westward expansion and post-Civil War national consolidation, the survey aimed to map the landscape for military strategy, settlement planning, and scientific research. The photographs preserved a visual account of the geological features, cultural heritage, and environmental landscapes of the region, capturing a moment when the American West was on the cusp of profound transformation. Both photographers approached the utilitarian demands of the survey with distinctive artistic sensibilities. O’Sullivan’s photographs captured the awe and immensity of the region, portraying rugged geological formations, river canyons, and ancient ruins. Bell’s images emphasized the overwhelming scale and depth of the land, typifying stereoscopic techniques through bold vertical compositions that drew the viewer’s eye into its dramatic and layered expanses. Together, their work resonated as visual expressions of Manifest Destiny while preserving the environmental and cultural features of an increasingly altered region.
O’Sullivan’s artistic vision emphasized the interplay of light and shadow, the stark contrasts of the arid West, and the scale of its formations, often juxtaposed against tiny human figures or survey equipment. His mastery of the wet-plate collodion process, a demanding technique requiring swift action to prepare, expose, and develop glass negatives while still wet, produced images of extraordinary clarity and texture. Bell complemented this with his use of the dry-plate process, involving tannic acid-treated collodion-coated plates, which, though less immediate, provided greater flexibility in the unpredictable conditions of the field. These technical choices reveal a deliberate effort to convey the monumental and surreal qualities of the landscape, offering an almost theatrical experience of place.
Wheeler Survey was not merely records of exploration but works that redefined the boundaries between art and science. Initially issued in government albums (1874–75) and shown at the 1876 Centennial Exhibition in Philadelphia, the photographs were later reintroduced to art audiences through MoMA’s The History of Photography: From 1839 to the Present Day (1937) and the Smithsonian American Art Museum’s Framing the West: The Survey Photographs of Timothy H. O’Sullivan (2010). Critics and historians, including Ansel Adams, have praised the haunting beauty and modernist qualities of O’Sullivan’s images. Substantial holdings at the Library of Congress, the Metropolitan Museum of Art, and other institutions—alongside facsimile editions—have sustained study and display. While Bell’s contributions were integral, his role is often overshadowed by O’Sullivan’s prior acclaim and the broader recognition of his artistic style, which dominated critical discussions of the project. Together, their combined efforts continue to shape interpretations of the survey as a profound intersection of history, art, and environmental documentation.
