About this map

Colorado River Aqueduct infrastructure dominates the desert floor in this mid-1980s survey, showing a complex system of dikes, levees, and Siphon points designed to manage water through the arid landscape. The map captures a transition point between the Eagle Mountains and the Coxcomb Mountains, where the broad Chuckwalla Valley meets the Pinto Basin.

Industrial activity is evident at the Eagle Mountain Mine Dump, a significant landmark on the southwestern edge of the sheet. Natural water features like Pinto Wash and Long Wash emphasize the drainage patterns that define the region's topography. Much of the northern area is protected within the Joshua Tree National Monument, including designated wilderness areas. Historical water sources such as Pinto Wells provide evidence of early desert travel and survival in this demanding terrain.
