About this map

Chemehuevi Indian Reservation lands dominate the western desert landscape of this 1970 survey, where the Chemehuevi Mts rise above the Chemehuevi Valley. Along the eastern border, the Colorado River swells into Lake Havasu, creating a complex shoreline defined by the Havasu National Wildlife Refuge. The map captures a specific moment of local development near the water, showing a Trailer Park and street grids like Crystal Beach Rd and Sunrise Dr emerging in the arid terrain.

Evidence of much older human presence is preserved at the Picture Rock Petroglyphs near the entrance to Mohave Canyon. This intersection of indigenous history and modern recreation is further marked by the Chemehuevi Landing Field and numerous named inlets such as Jops Harbor and Catfish Bay, illustrating how the impounded river transformed the canyon floor into a destination for boaters and naturalists.
