The Iron Mountain Pumping Plant serves as a critical infrastructure hub on this 1943 military survey, highlighting the massive engineering required to move water through the California desert. Prepared for the California-Arizona Maneuver Area, the map documents the early operations of the Metropolitan Aqueduct and its accompanying Tunnel systems that pierce the Iron Mountains. Evidence of wartime utility is clear, with the Army Pump Sta and various water points like Salt Marsh Tank and W-40 scattered across the arid landscape. To the north, the Atchison Topeka and Santa Fe railroad crosses the northern edge of Danby Lake (Dry), while the Granite Shaft in the southern Granite Mountains points to the area's mineral exploration history during this mid-century period of rapid mobilization.
