1986 Map of Pilot Mountain

About this map

The Chuckwalla Mountains dominate this 1986 Riverside County landscape, characterized by high peaks and desert washes. This provisional survey captures a remote portion of the California desert where water sources like Corn Springs and Gulliday Well were critical for navigation and survival. To the south, the boundary of the Chocolate Mountain Aerial Gunnery Range marks a significant military footprint on the land, separating restricted defense zones from the open desert. Significant elevations such as Pilot Mountain, Black Butte, and Sharp Peak provide the primary navigational landmarks across this arid terrain. Small-scale mining activity is evidenced by scattered prospects, while seasonal drainages like Ship Creek illustrate the natural drainage patterns of the Chuckwalla range before they disappear into the valley floors.
