About this map

The Colorado River defines the border between Arizona and California in this desert landscape, winding through a complex network of wetlands and backwaters. Notable riparian features like Regan Slough, Adobe Lake, and Nortons Lake demonstrate the historical hydrologic character of the river corridor before modern modifications significantly altered these seasonal basins. To the east, the terrain rises into the Trigo Mountains, where the landscape is carved by significant drainages such as Red Cloud Wash and Black Rock Wash.

Evidence of desert survival and transit is found in the presence of Carrizo Spring and Carrizo Well tucked into the foothills. Dramatic topographical features, including Bear Canyon Bluff and Bear Canyon Falls, mark the transition from the arid uplands of Paradise Valley down toward the river's edge. Primitive routes like Indian Pass Rd and the Stewart Lake Trail provide the primary access through this remote borderland.
