About this map

San Bernardino National Forest and the Cahuilla Indian Reservation dominate this landscape, reflecting a complex history of land management and indigenous presence. The map reveals a transition from the elevated terrain of Little Cahuilla Mtn and Cahuilla Mtn down into the lower basins of Reed Valley and Creek Valley Springs. Water sources are vital features in this arid environment, evidenced by the development of Lake Riverside and the preservation of natural sites like Rancho Spring and Duval Spring.

Evidence of local industry and infrastructure appears in the form of the Williamson Mine and several other unlabeled mine and prospect sites. Remote aviation facilities, including a Landing Strip and Air Strip, alongside the Forest Service Station, suggest the area’s role in fire management and resource monitoring. The small settlement of Graves and scattered water tanks further illustrate the localized ranching or residential footprint within these foothills during the early 1980s.
