About this map

The San Bernardino National Forest dominates the southern reaches of this landscape, where the San Bernardino Mountains meet the Bighorn Mountains. This arid transition is marked by a complex network of canyons and high peaks, including Tip Top Mtn and the Granite Peaks. Historically significant water sources are scattered throughout the high desert terrain, appearing as named seeps such as Rattlesnake Spring, Two Hole Spring, and Viscera Spring.

Transportation through this demanding geography is defined by isolated desert tracks and established routes like Old Woman Springs Rd and Rattlesnake Canyon Rd. The map illustrates the meeting of desert basins and mountain ranges, with Johnson Valley and Lone Valley providing level ground between the steep grades of Rattlesnake Canyon and Bighorn Canyon. This survey captures the region's character as a crossroads of high-altitude forest and open desert flats.
