1951 Map of Haiwee Reservoir

About this map

The Los Angeles Aqueduct and the Haiwee Reservoir dominate the western edge of this Inyo County landscape, illustrating the critical mid-century infrastructure redirecting water from the Owens Valley. To the east, the terrain rises into the volcanic and geothermal features of the Coso Range, where evidence of ancient and modern activity meets. Locations like Indian Petroglyphs sit in proximity to industrial and geothermal sites such as the Thorndyke Mine and the steaming fumaroles of Coso Hot Springs. Small settlements and travel stops like Dunmovin, Coso Junction, and Rose Spring line the corridor of U S Highway 395 and the Southern Pacific railroad. The map also records several family-named landmarks and ranch sites, including Lewis Ranch and Sykes, providing a record of habitation in the shadow of Sugarloaf Mountain and the high basins of Cactus Flat.
