2021 Map of Isla Pinta

About this map

Sierra Pinta and the Isla Pinta formation dominate this arid corner of Arizona, showing a landscape defined by narrow canyons and isolated water sources. The map details a transition from the broad Mohawk Valley in the north to the expansive Tule Desert in the south, separated by the steep ascent of Sunday Pass. Researchers can identify critical survival points for desert travel, such as Heart Tank and Eagle Tank, which are essential features in this water-scarce environment. Several distinct drainages like Hummingbird Canyon, Chia Canyon, and Eagle Canyon cut through the central highlands, providing clear evidence of the erosion patterns that shape the regional geography. This survey provides a precise look at the township and range divisions across the Yuma County desert, preserving the nomenclature of the ridges and washes that have guided travelers through this territory for decades.
