ORIGINAL CAPTION: This map shows land held by the US government and Native American Indians. This includes national parks, national wildlife refuges, military reservations, Federal prisons, and public-domain land. It also shows lands owned or administered by the Federal Government, including the Bureau of Land Management, the Bureau of Reclamation, the U.S. Department of Agriculture Forest Service, the Department of Defense, the U.S. Fish and Wildlife Service, the National Park Service, the Tennessee Valley Authority, and other agencies. It's import to note that this map doesn't show Federal land under 640 acres or long, relatively narrow features like parkways and scenic rivers. Indian lands, administered by the Bureau of Indian Affairs, are available in the Indian Lands of the United States map layer. (US Dept. of the Interior, USGS)
