About this map

The Cottonwood Valley dominates the western portion of this mid-century survey, where the Colorado River flows through Lake Mohave along the border of Nevada and Arizona. This desert landscape is part of the Lake Mead National Recreation Area, characterized by a transition from the water's edge up into the steep elevations of the Black Mountains.

Evidence of historical desert industry and travel is found in the southeastern corner, where the Portland Mine is located near Portland Wash. Access to this arid interior is marked by the Lost Cabin Jeep Trail, which leads toward the Lost Cabin landmark and Lost Cabin Wash. High points like Vabm 4199 and VABM Pass 4162 provide distinct topographical reference points for those tracing old mining routes or territorial boundaries between Clark Co and Mohave Co.
