2018 Map of Little Chuckwalla Mountains

About this map

The Chuckwalla Mountains rise sharply in the northern portion of this quadrangle, creating a distinct topographical divide as the desert floor transitions into the Black Hills to the south. Historically significant pathways traverse this arid landscape, including The Bradshaw Trl, a vital nineteenth-century stage route, and the Butterfield Trl. The survey captures the crossing of these trails near the boundary of Riverside and Imperial Counties, highlighting the corridor's role as a transit artery through the Colorado Desert. Settlement here is defined by these travel routes rather than towns, with Graham Pass Rd providing one of the few formal access points through the high terrain.
