A picture is worth 1,000 words: Who owns the West?

Earlier this morning I linked to Michelle Malkin who describes the GOP's victory in stopping the Obama administration's efforts to use environmental regulations as a federal land grab.  How much land is actually up for grabs?

This startling map from Big Think details the percentage of state territory owned by the federal government (in 2004):

The United States government has direct ownership of almost 650 million acres of land (2.63 million square kilometers) – 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.
