About this map

The Colorado River defines the rugged border between Arizona and California, winding through a corridor of lakes and wetlands including Taylor Lake, Ferguson Lake, and Walker Lake. This post-war survey highlights the Imperial National Wildlife Refuge and the legacy of mining in the surrounding Trigo Mountains and Chocolate Mountains. Notable industrial sites like the Red Cloud Mine, Black Rock Mine, and the Clip Mill Site point to a history of hard-rock extraction in this desert landscape.
