The Owyhee Mountains are a mountain range in Owyhee County, Idaho and Malheur County, Oregon. [2]

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. [3]

The southeastern end of the range including the old mining area west of Silver City is referred to as the Silver City Range. [4] About 8.3 kilometres (5.2 mi) west of Silver City is the De Lamar ghost town in Jordan Creek below the mine workings on De Lamar Mountain to the south. [4] The area was active in the late 1880s. In the 1970s mining began again with the development of open pit silvergold mines on De Lamar Mountain. [5] [6]
