The U.S. Geological Survey and the U.S. Bureau of Mines conducted field investigations to evaluate the mineral resources of the Manzano Wilderness, Torrance and Valencia Counties, N. Mex., during 1980 and 1982. This map complements the mineral resource appraisal of the Manzano Wilderness (Maxwell and others, 1983). Field studies by the Bureau of Mines included a reconnaissance of mines, prospects, and mineralized areas. From workings within and near the wilderness, 107 samples were taken and analyzed.
