1984 Map of West of Leach Spring

About this map

Pilot Knob Valley serves as the central focal point of this Mojave Desert landscape, flanked by the Quail Mountains and the Granite Mountains. The 1984 survey reveals a region dominated by government land use, where the U S Naval Reservation and the Fort Irwin Military Reservation converge. The San Bernardino Meridian passes through the center of the sheet, providing a critical surveying baseline for the surrounding township and range divisions. Human movement through this arid environment is largely defined by Randsburg Road, which cuts across the valley floor. Myrick Spring stands out as a rare water source in the southern reaches of the quadrangle, a vital point for anyone tracing the natural history of this portion of San Bernardino County during the late twentieth century.
