The Owyhee Mountains are a mountain range in the western United States, located in Owyhee County, Idaho, and Malheur County, Oregon.
Mahogany Mountain and the associated volcanic craters of the Lake Owyhee volcanic field are in the Owyhee Mountains of Oregon just east of the Owyhee Reservoir on the Owyhee River.Cummings, Michael L., et al., Stratigraphic and structural evolution of the middle Miocene synvolcanic Oregon-Idaho graben, Geological Society of America Bulletin, 2000; v. 112, no. 5; pp. 668-682
The southeastern end of the range in Idaho, including the old mining area west of Silver City, is referred to as the Silver City Range.Murphy, Idaho, 30x60 Minute Topographic Quadrangle, USGS, 1986 About west of Silver City is the De Lamar ghost town in Jordan Creek below the mine workings on De Lamar Mountain to the south. The area was active in the late 1880s. In the 1970s, mining began again with the development of open pit silver–gold mines on De Lamar Mountain.Bonnichsen, Bill; Epithermal Gold and Silver Deposits Silver City–De Lamar District, Idaho, University of Idaho, Idaho Geological Survey, Technical Report 83-4, 1983 PDF De Lamar, Idaho, 7.5 Minute Topographic Quadrangle, USGS, 1990
