2018 Map of San Bernardino Wash

About this map

Joshua Tree National Park encompasses the majority of this desert landscape, where the northern Pinto Mountains meet the vast drainage systems of the Pinto Basin. The terrain is defined by its arid hydrology, characterized by the prominent San Bernardino Wash and Pinto Wash, which carve through the basin floor to collect seasonal runoff from the surrounding peaks. To the south, the foothills of the Eagle Mountains rise sharply, marking the edge of this section of the Mojave Desert. The map reveals the intricate natural drainage network of the Smoke Tree Wash as it descends toward the central basin, illustrating the stark environmental patterns that dictate the geography of this protected wilderness area in Riverside County.
