Photographs of Arizona, Nevada, and Utah

Mounted photographs of Arizona, Nevada, and Utah created by Timothy H. O'Sullivan, with a single photographic print by William Bell, that document the Geographical Surveys West of the 100th Meridian led by George Montague Wheeler for the United States War Department, 1871-1872. O'Sullivan created photographs from the 1871 expedition, and Bell created photographs from the 1872 expedition. Manuscript captions pasted on versos of mounts describe geological formations in detail, and are signed "G.K.G" (Grove Karl Gilbert), geologist with the Wheeler expedition 1871-1874

Photographs by O'Sullivan depict several locations along the Colorado River in the Black Canyon and the Grand Canyon. Photographs of Nevada include a view of men and women in the mining town of Logan and a view of eroded strata near Cottonwood Springs. A photograph of Utah consists of a detailed view of a rock marked with striations from wind erosion near Grand Wash, Utah (misidentified by a typescript caption as below Fortification Rock, Arizona).

The photograph by Bell shows the Colorado River and Marble Canyon (identified as Grand Cañon) near the confluence with the Paria River in Arizona

Accompanied by an architectural detail drawing with graphical representations of a scarab, dagger, celestial symbols, and a horned toad or rodent, as well as manuscript passage attributed to Pliny the Elder
