The main mission of the 1872 expedition was to document the geology and topography of the Yellowstone area, particularly the Snake and Missouri Rivers. John M. Coulter and Assistant Naturalist Walter Platt collected numerous fossil, animal, and plant specimens. Coulter also made observations on the differences in the plant life in the various environments they encountered, from the desert to the Geyser Basins. The first leg of their journey went through the region between Ogden and the Teton Basin. Additional Sources: Rodgers, Andrew Denny. John Merle Coulter: Missionary in Science.
