2012 Map of Mopah Peaks

About this map

Turtle Mountains dominate this arid landscape in eastern San Bernardino County, where the topography is defined by ancient volcanic formations and desert drainage systems. The map prominently features the distinctive Mopah Peaks and the towering landmark of Castle Rock, both of which have served as critical navigational beacons for travelers through the Mojave Desert for generations. Natural water flow is ephemeral here, traced by the course of Gary Wash as it winds through the northern portion of the quadrangle. This 2012 survey captures the area's geological character with precision, documenting the primary peaks and landforms that have remained constant while surrounding road networks and infrastructure evolved on the desert floor.
