2021 Map of Skeleton Pass

About this map

Fenner Valley and the Mojave Desert converge in this arid corridor of San Bernardino County. The landscape is defined by the sharp transition from the broad alluvial floor to the rising elevations of the Ship Mountains in the southwest. A network of historical transit routes, such as Skeleton Pass Rd and the Sunset Trl, cross the valley, following natural topographic breaks like Skeleton Pass. These trails and unimproved roads suggest a history of crossing this desert expanse, where water drainage has carved prominent features like Rattlesnake Canyon and Carbonate Gulch into the surrounding highlands. The mapping reflects a modern era of desert management and recreation where designated trails like the Ship Mountain Road Trl provide the primary access to the backcountry.
