Abandoned uranium mines are found in all corners of the Southwest. In New Mexico, about 1,100 sites where mining, milling or exploratory drilling occurred lie abandoned, mostly in the Grants Mineral Belt. Hundreds more dot the greater Navajo Nation, in Arizona, Utah and Colorado. With big money flowing in the coming decade from settlements with large corporations and the U.S. government for contamination, cleanup of hundreds of abandoned mines will finally begin after decades of neglect.
