2021 Map of San Gorgonio Mountain

About this map

San Gorgonio Mtn dominates this high-altitude landscape within the San Bernardino National Forest, where extreme elevations define the drainage patterns of the San Gorgonio River and the S Fork Santa Ana River. The map highlights a complex network of glacial and tectonic features, including The Tarn, Dollar Lake, and Dry Lake, which sit below prominent massifs like Jepson Peak and Charlton Peak. To the east, the Whitewater Wild and Scenic River corridor begins its descent through steep canyons. The southern portion of the sheet transitions toward the Burro Flats and the county boundary between San Bernardino and Riverside. A extensive trail system, including the Sky High Trl and Vivian Creek Trl, connects remote landmarks like Mine Shaft Saddle and Ten Thousand Foot Ridge, tracing the paths used by backcountry travelers and early forest rangers through this alpine terrain.
