2018 Map of Middle Mountains South

About this map

The Mid Mountains dominate the northwestern portion of this arid Yuma County landscape, where steep topography transitions into the expansive Castle Dome Plain. This desert environment is characterized by large drainage systems such as Castle Dome Wash, which cuts a broad path through the central valley. A prominent Natural Arch is located among the high ridges, serving as a distinct natural landmark in this sparsely populated region. Human activity is primarily represented by the Castle Dome Mine Rd, which traverses the rugged terrain and links the area to historical mining operations beyond the quadrangle borders. The map detail reflects a classic desert Basin and Range land use pattern, where development is dictated by the passage of washes and the accessibility of mineral-rich mountain passes.
