Abstract: The Hawk Mountain Wilderness Study Area (OR-001-146A) encompasses approximately 69,640 acres along the Oregon-Nevada State line.The study area lies in southwestern Harney County, Oreg., approximately 20 mi southeast of Fields, Oreg., and 12 mi west of Denio, Nev.In this report, "study area" or "wilderness study area" refers to that area for which the mineral survey was requested by the U.S. Bureau of Land Management.Geologic, geochemical, and geophysical surveys of the study area were conducted by the U.S. Geological Survey and U.S. Bureau of Mines to evaluate the identified (known) mineral resources and to assess the mineral resource potential (undiscovered).No resources were identified in the study area.No mines or claims were observed in the study area nor are there any records of production or oil, gas, or geothermal leases for the study area.The study area is underlain by Tertiary volcanic rocks that are locally hydrothermally altered and silicified.In this region, altered rocks may host deposits of mercury, silver, and gold and industrial minerals (clay and zeolite).In
