About this map

The Los Angeles Aqueduct dominates this high-desert landscape of Rose Valley, providing a clear record of the infrastructure required to move water across the Eastern Sierra during the early 1980s. The map illustrates the region's intersection of utility and defense, bordering the China Lake Naval Weapons Center and containing critical infrastructure like the Power House and Gaging Station near Rose Spring.

Small settlements such as Dunmovin and Coso Junction mark the corridor between the Inyo National Forest and the vast flats to the east. The rugged terrain is deeply etched by features like Tunawee Canyon and Portuguese Bench, while localized industrial activity is evidenced by an Open Pit Mine and a Shaft. This provisional survey preserves a specific moment in the rural development of Inyo County before subsequent land use changes altered the character of these desert outposts.
