Pleasant Valley and the northern slopes of the Hexie Mountains dominate this arid landscape in eastern Riverside County. The drainage network is defined by a series of prominent ephemeral waterways, most notably the Fried Liver Wash and Pinto Wash, which carve through the basin floor. The human imprint on this desert terrain is concentrated along Pinto Basin Rd, which provides access to unique landmarks like the Cholla Garden. The map illustrates a vast, undeveloped area where topography is the primary feature, showcasing the transition from mountain canyons like Wilson Canyon to the broad, flat reaches of Washington Wash. This survey serves as a precise record of the geological and botanical features of the California desert as they existed in the early 21st century.
