About this map

Sierra Pinta dominates this arid landscape, its steep contours rising sharply above the surrounding desert floor. This 2018 survey documents a remote corner of Yuma County where the high peaks of the range are cut by distinct drainages like Hummingbird Canyon and Chia Canyon. The terrain is characterized by the transition from the broad, flat Tule Desert to the west into the more complex geography of the Mohawk Valley to the northeast.

Critical water sources, essential for survival in this environment, are noted at Heart Tank and Eagle Tank, located along the eastern slopes near Eagle Canyon. Travel through the range is limited to natural corridors like Sunday Pass, which provides a crossing point through the northern reaches of the Sierra. This map also identifies the isolated landform of Isla Pinta, standing apart from the main range in the northwest quadrant.
