No.14 Grotto Spring, Grand Cañon, Colorado River. (F.136)
From 1871-1879, Lieutenant George M. Wheeler (1842-1905), army engineer and surveyor, led a series of geographical surveys with the purpose of mapping the land west of the 100th Meridian through much of California, Nevada, present-day Arizona, New Mexico, and Colorado. Timothy H. O’Sullivan (1840-1882) and William Bell (1839-1915) were the primary photographers who traveled on the surveys from 1871-1873 documenting the geological features of the American West. This photograph, taken by O'Sullivan in 1871 from the Grand Cañon (today known as Grand Canyon National Park in Arizona), features two figures in the foreground and layers of receding rocks in the background. The full title reads: "The water flows from the rocks above, and the umbrella-shaped rock about its tufa, that has been formed by deposition from the mineral constituents of the water. The light spot seen through and beyond is the sand-beach of the river. Looking through this Grotto is seen in the distance the walls of the Grand Cañon, 3500 feet in height on either side." From the Miss Crete Rose Collection. The original negative number, 136, is written on both images, likely by the photographer.
