2011 Map of Palomas Mountains SW

About this map

Palomas Mountains and the southern reaches of the Tank Mountains anchor this arid desert landscape in Yuma County. The map documents a topography defined by complex drainage patterns, with numerous unnamed ephemeral washes descending from the mountain slopes and weaving across the desert floor. This 2011 survey by the U.S. Geological Survey illustrates the transition from the rugged upland terrain to the surrounding alluvial plains, capturing a wilderness area largely devoid of permanent settlements or modern infrastructure. The detailed contour work provides insight into the natural watershed system and the geological structure of these southwestern Arizona ranges.
