2015 Map of Clarks Pass

About this map

Joshua Tree National Park spans the central portion of this 2015 survey, marking the transition where the Sheep Hole Mountains of the north meet the Pinto Mountains to the south. This arid landscape is defined by its topographic extremes, from the high desert peaks to the broad expanse of the Pinto Basin. Modern infrastructure is represented by Highway 62, which winds through Clarks Pass, a critical corridor for travel through the eastern Mojave Desert. The map also captures the administrative boundary between San Bernardino and Riverside counties, which bisects the desert floor and the mountainous terrain. For those interested in the environmental history of Southern California, the map documents the preserve's boundaries and natural landforms as they were managed in the early 21st century.
