About this map

The Plomosa Mountains dominate this arid landscape in La Paz County, where the desert floor is carved by a network of drainage channels. The Plomosa Pass provides a natural corridor through the range, shadowed by prominent peaks like Guadalupe Mtn and Scaddan Mtn. These geological features shaped early movement and settlement in the region, seen here in the proximity of Plomosa and the small station of Boxcar.

Ephemeral water sources, such as Lazarus Tanks, were essential for travel and small-scale mining operations reflected by Mitchell Mine Rd and Gold Nugget Rd. The map also details several desert washes including Italian Wash, Poormans Wash, and Colorado Wash, which illustrate the complex hydrology of this high-desert environment. To the south, the distinctive Elephant Back Mtn stands as a landmark for those navigating the rugged terrain between the mountains and the valley floors.
