The Copper Mountains dominate the southwestern quadrant of this 2018 survey, their jagged contour lines indicating a sharp vertical rise from the desert floor. To the east, the landscape transitions into the wide, low-lying expanse of the Mohawk Valley, a terrain defined by subtle elevation changes and the desert drainage patterns of Yuma County. This map highlights the stark contrast between the steep mountain slopes and the broad valley floor, divided clearly by the Public Land Survey System grids such as t10s r17w and t10s r16w. The lack of modern settlement and roads on this sheet underscores the arid, undeveloped character of this portion of the Arizona desert.
