About this map

San Gorgonio Mtn dominates the high-altitude landscape of the San Bernardino National Forest on this 2018 survey. The terrain is defined by dramatic elevation changes, from the alpine reaches of Jepson Peak and Charlton Peak down to the drainage basins of the S Fork Santa Ana River and the S Fork Whitewater River. This map captures a modern view of a region critical to California's watershed, where seasonal water sources like The Tarn and Lodgepole Spring sustain the environment between prominent ridges like Ten Thousand Foot Ridge.

While largely unpopulated, the southern portion of the sheet shows historical land use through features like Burro Flats and the naming of Sawmill Canyon and Burnt Canyon near the Riverside County line. Notable landmarks for navigation through the steep canyons include Gunsight Pass and the distinctive Mill Creek Jumpoff. The presence of Mine Shaft Saddle north of the main peak points to the area's prospecting history, preserved here alongside more recent markers like Raywood Flat Rd.
