About this map

Plomosa Mountains dominate this arid landscape, where the primary route of travel through the range is defined by Plomosa Pass. This 2011 topographic survey reveals a rugged interior where desert hydrology is the most prominent feature. A network of ephemeral drainages, including Poormans Wash, Italian Wash, and Chalk Wash, carve the terrain around peaks like Elephant Back Mountain and Guadalupe Mountain.

Evidence of human activity is concentrated along the central transport corridor, notably marked by Gold Nugget Rd. Local history is anchored at the small settlements of Plomosa and Boxcar, while the inclusion of Lazarus Tanks highlights the critical importance of water storage in this section of La Paz County. The mapping also identifies Scaddan Mountain and various minor washes, illustrating the complex drainage patterns feeding into the desert floor.
