2015 Map of Washington Wash

About this map

Joshua Tree National Park encompasses the central portion of this desert landscape, where the Hexie Mountains and Cottonwood Mountains meet. The terrain is defined by a complex drainage network, characterized by several significant seasonal washes that cut through the Mojave Desert. Notable among these are Washington Wash and Porcupine Wash, which flow through the northern reaches, while Smoke Tree Wash and Pinkham Wash drain the southern sections. This 2015 U.S. Geological Survey representation documents the arid geography of the Pinkham Canyon area, providing a precise record of elevations and landforms such as Monument Mtn. Human presence is represented primarily by primitive access routes like the Pinkham Canyon Trl and Thermal Canyon Rd, tracing the paths through the high-desert basins.
