2021 Map of McCoy Spring

About this map

McCoy Mountains rise sharply in the northeastern corner of this Riverside County landscape, providing a stark topographic contrast to the broad expanse of the Chuckwalla Valley below. This arid desert region is defined by complex drainage patterns and alluvial fans that spread across the valley floor, illustrating the hydraulic character of the eastern Colorado Desert. A primary focal point for local history and survival in this environment is McCoy Spring, a critical water source situated high within the mountain range. The map clearly delineates the public land survey system grid, including townships t5s r19e and t6s r20e, which historically governed the mining and grazing claims throughout this remote terrain.
