About this map

Collins Valley and the surrounding desert peaks are defined by a complex network of seasonal drainages and remote springs in this late 1990s revision. This terrain, situated at the boundary of Anza-Borrego State Park and the Santa Rosa Mountains State Wilderness, shows a landscape where water is the primary architect of human and natural activity. The map identifies critical water sources like Cottonwood Spring and Hidden Spring, alongside the lush corridors of Middle Willows and Lower Willows that provide respite from the arid environment.

Evidence of the region's surveying history is preserved through markers like BM 1980 and Monitor Hill. The land is deeply carved by numerous washes and canyons, including Coyote Canyon, Salvador Canyon, and Rockhouse Canyon, which converge toward the main channel of Coyote Creek. This cartography highlights the administrative intersection of the San Bernardino National Forest and state park lands, emphasizing a protected corridor of high desert wilderness along the Riverside and San Diego county line.
