William Henry Jackson spent the years between 1870 and 1879 as the official photographer for Ferdinand V. Harden’s U.S. Geological and Geographical Survey of the Territories. While working on this federally supported expedition, Jackson photographed the largely unsettled Western frontier, including the region that is now called Yellowstone National Park. Jackson’s photographs of Western subjects hung in the parlors of thousands of homes, and stimulated interest in the region among the business people and tourists alike.
