Maps showing the distribution and relationships of selected metals in heavy-mineral concentrates of the Hells Hole Further Planning Area (RARE II), Greenlee County, Arizona, and Grant County, New Mexico

The Wilderness Act (Public Law 99-577, Sept. 3, 1964) and related acts require the U.S. Geological Survey and the U.S. Bureau of Mines to survey certain areas on Federal lands to determine their mineral resource potential.  Results must be made available to the public and be submitted to the President and the Congress.  This report presents the results of a geochemical survey of the Hells Hole Further Planning Area (RARE II) in the Apache National Forest, Greenlee County, Ariz. and the Gila National Forest, Grant County, N. Mex.  The Hells Hole Further Planning Area (03138) was classified as a proposed wilderness and further planning area during the Second Roadless Area Review and Evaluation (RARE II) by the U.S. Forest Service, January 1979.
