2021 Map of San Bernardino Wash

About this map

Joshua Tree National Park encompasses a significant portion of this landscape, where the southern reaches of the Mojave Desert meet a complex network of dry desert drainage systems. The map shows the vast Pinto Basin framed by the prominent Pinto Mountains to the north and the Eagle Mountains to the southeast. This terrain is characterized by its ephemeral hydrology, defined by the extensive paths of the San Bernardino Wash, Pinto Wash, and Smoke Tree Wash. These features highlight the natural corridors through which seasonal waters move across the basin floor, shaping the arid geography and influencing the location of native flora. The grid of the Public Land Survey System overlays these features, marking sections across the desert expanse within Riverside County.
