Green River Cliffs by Moonlight

Thomas Moran (1837-1926) is a well-known painter of landscapes in the American West. As a member of the Hayden Geological Survey of 1871, his paintings of the Yellowstone area were instrumental in the establishment of Yellowstone National Park. The painting of Green River, Wyoming, frequently hangs in the Office of the Secretary, Department of the Interior, as representative of the many lands cared for by the Department.
