2021 Map of Middle Mountains South

About this map

Mid Mountains dominate the northern terrain of this Yuma County landscape, where the elevation rises toward a prominent Natural Arch. The geography is defined by the sweeping transition from these rocky uplands down into the expansive Castle Dome Plain, a characteristic desert basin floor. Access through this arid environment is anchored by the Castle Dome Mine Rd, which skirts the eastern edges of the mountains. This corridor follows the natural drainage patterns of the Castle Dome Wash, illustrating the traditional routes used to navigate the desert between the high peaks and the open plains. The map provides a clear record of the modern road network, including Route 95, as it intersects with older mining access paths in a region historically shaped by mineral exploration.
