Copper Mountains dominate the western portion of this 2011 survey, where the arid landscape is defined by extensive drainage systems and sparse water resources. The terrain is largely undeveloped, reflecting the character of Yuma County’s desert expanses. Human presence is evidenced primarily by remote infrastructure such as Betty Lee Tank, which highlights the importance of water catchment systems in this arid environment. The map shows a network of unpaved roads and tracks that navigate the foothills, providing access to the higher elevations of the range and the various washes that cut through the surrounding desert floor.
