Federal ownership of U.S. land

"The United States government has direct ownership of… nearly 30% of its total territory. These federal lands are used as military bases or testing grounds, nature parks and reserves and indian reservations, or are leased to the private sector for commercial exploitation (e.g. forestry, mining, agriculture). They are managed by different administrations, such as the Bureau of Land Management, the US Forest Service, the US Fish and Wildlife Service, the National Park Service, the Bureau of Indian Affairs, the US Department of Defense, the US Army Corps of Engineers, the US Bureau of Reclamation or the Tennessee Valley Authority. This map details the percentage of state territory owned by the federal government." (Click image to superdupersize.)

Offered without editorial commentary on my part, just for its interesting content. Found at the Strange Maps blog, which has many other interesting maps. One needn't have an interest in cartography to enjoy that website - indeed, cartography per se is almost irrelevant, since the focus is on unique presentations of data using the "map" format.
