2015 Map of Mud Hills

About this map

Rainbow Basin serves as a geological centerpiece in this high-desert landscape north of Barstow, where complex drainage patterns have carved deeply through the Mud Hills. The terrain is characterized by a series of dramatic erosional features, including the winding corridors of Fossil Canyon and Coon Canyon. These canyons provide a look at the arid topography of the Mojave Desert as it was mapped in 2015. Human activity in this desolate region is primarily marked by a sparse network of access routes, most notably Fossil Bed Rd and Copper City Rd, which navigate the varying elevations between Owl Canyon and the surrounding peaks. The map detail reflects the region's importance for geological study and recreational exploration, clearly delineating the public land survey system grids that organize this expansive reach of San Bernardino County.
