1984 Map of Casa Diablo Mtn

USGS Topo · Published 1987

About this map

Casa Diablo Mtn dominates the high desert terrain where the eastern Sierra meets the Great Basin, overlooking the dramatic descent of the Owens Gorge. This 1980s-era documentation captures a landscape defined by significant geologic and industrial features, including the sprawling Volcanic Tableland and the Casa Diablo Mine located on the mountain's northern slopes. The map traces the critical hydroelectric infrastructure along the Owens River, marking the locations of the Powerhouse, Surge Tank, and a Gaging Station that manage the region's water resources. To the south, the terrain transitions toward Sherwin Hill, while the western boundary is defined by the Inyo National Forest. Historic transportation routes are well-preserved here, such as the Casa Diablo Road and the Old Grade, providing a clear view of how the area was navigated before modern realignments.
