2018 Map of Mopah Peaks

About this map

Mopah Peaks dominate the eastern landscape of this 2018 survey, providing a focal point for the Mopah Range in San Bernardino County. This desert terrain, part of the wider Mojave Desert, is characterized by dramatic topographic rises and deep drainage systems like Gary Wash. The presence of Mopah Spring indicates a critical water source in an otherwise arid environment, essential for the local ecology of the Turtle Mountains. Farther south, the distinct formation of Castle Rock stands as a prominent landmark. The map illustrates the complex ridgelines and elevation changes that define this corner of California, showing the relationship between these peaks and the surrounding washes that channel seasonal runoff across the basin.
