The Mojave Desert terrain dominates this 2015 U.S. Geological Survey topographic study, illustrating the convergence of several significant geologic formations in San Bernardino County. In the northwestern quadrant, the Bullion Mountains rise sharply, while the southern edge of the map is defined by the Sheep Hole Mountains. This arid landscape is bisected by N Amboy Rd, which serves as the primary corridor through these dry washes and alluvial fans. The map provides a high-resolution view of the contemporary topography and drainage patterns between these ranges, showing the relationship between the road network and the natural elevation changes in this sparsely populated desert region.
