About this map

Mono Basin and the volcanic terrain of the Mono Craters dominate this mid-century survey of the eastern Sierra region. The map documents a landscape heavily influenced by regional water management, featuring the Aqueduct, the Mono Tunnel, and the Mono Craters Tunnel, which serve as critical infrastructure for the Los Angeles Water District. To the east, the high elevations of Cowtrack Mountain and Granite Mountain rise above the Big Sand Flat, while the lower elevations are marked by the presence of Inyo National Forest.

Industrial and transport history is preserved through the footprint of the Mono Mills (Site) and the winding path of the Old Railroad Grade. These features point to a late-19th-century timber industry that once supplied the nearby mining boomtowns. The drainage patterns of the Owens River and Sagehen Creek are mapped in detail alongside numerous family-named landmarks like Johnny Meadow and Bald Mtn Spring, providing a clear view of the water sources that sustained ranching and forestry in this high-altitude environment.
