About this map

The Chocolate Mountains dominate the northern landscape of this Imperial County desert terrain, where steep ridges give way to the broad alluvial plains of the Ninemile Wash. This 2015 survey reveals a stark, arid environment defined by seasonal drainage patterns and sparse infrastructure. The wash itself bisects the quadrangle, serving as the primary natural corridor through which water travels during infrequent desert storms.

Human activity is concentrated along the western and eastern edges, marked by the presence of Gfoc Mine Rd and Ogilby Rd. These corridors suggest the ongoing industrial and transit importance of the region, specifically relating to mineral extraction and north-south travel across the Colorado Desert. The map captures a high degree of topographical detail within the mountainous sections, providing a clear record of the land's contours as managed by the Bureau of Land Management.
