The Colorado River serves as the central artery for this reconnaissance survey, tracing the high desert borders where Arizona, Nevada, and California converge. At the southern end of Pyramid Canyon, Camp Mohave and the surrounding U.S. Mil. Res. stand as key landmarks near the historic river crossing at Hardyville. The landscape is a network of arid valleys and mountain ranges, with the Black Mountains and Cerbat Range hosting a variety of early mining settlements and springs essential for survival.
