This museum, located on the first floor of the Interior Department building, has retained the flavor of the late 1930s, when it first opened to the public. The Department of the Interior consists of ten bureaus: Reclamation, Indian Affairs, Land Managment, Mineral Management, Surface Mining, US Geological Survey, US Fish and Wildlife, National Park Service, Office of the Secretary, and Policy, Budget and Administration. Seven of the 10 bureaus have gallery space in the museum. Their exhibits include artifacts, drawings, documents, diagrams, photos and paintings. Throughout the museum visitors can view the attractive dioramas depicting historic and characteristic scenes from the nation's past.
