1986 Map of Pilot Mountain

About this map

Chuckwalla Mountains define this high-desert landscape in Riverside County, dominated by the prominent peak of Pilot Mountain. The area is characterized by an intricate network of dry drainage features, most notably Corn Wash and Ship Creek, which illustrate the complex topography surrounding Sharp Peak. Historically, the presence of Corn Springs highlights a critical water source in an otherwise arid environment, serving as a vital point for travelers and early inhabitants moving through these desert ranges. This 1986 provisional edition, based on earlier field checks and aerial photography, meticulously records the elevation contours and natural landmarks of the region during a period of ongoing geographic documentation by the U.S. Geological Survey.
