By nature and by experience gained during the Civil War, O’Sullivan was ideally suited for the physical and creative demands required of the official photographer for the geological exploration of the fortieth parallel, led by the enterprising Yale geologist Clarence King. The goal of the expedition was to survey the geological structure and natural resources of a swath of territory 100 miles wide, from the eastern slopes of the Sierra Nevada Mountains across the Great Basin to the Rocky Mountains. While on the expedition in 1867–69 and 1872, O’Sullivan simultaneously pursued his own interest in perfecting a balanced, aesthetic style of landscape photography while providing a faithful record of the natural terrain. As typified in this print, he positioned the camera at a distance parallel to the majestic scenery, presenting a shallow, flattened depiction of space. The image describes in sharp detail the sheer beauty and rugged scale of this Western landscape.</div>
