About this map

Cahuilla Indian Reservation occupies the southeastern corner of this landscape, where the high desert terrain meets the foothills of the San Bernardino National Forest. The 1980s-era geography shows a transition between protected federal lands and private ranching interests, centered around the life-sustaining waters of Lake Riverside and Cahuilla Lake. High-elevation landmarks like Cahuilla Mtn and Little Cahuilla Mtn tower over the alluvial plains of Juan Diego Flats and Tripp Flats, while a network of seasonal drainages including Wilson Creek and Cahuilla Creek carve through the valleys.

Local history and industry are represented by the Williamson Mine and several other unnamed mine sites and prospects scattered across the slopes. The settlement of Graves and the Rancho Spring Forest Service Station serve as focal points for human activity in this otherwise sparse mountain environment. Notable infrastructure for the era includes a remote Landing Strip and Stanley Road, providing essential access to the interior of Wilson Valley.
