About this map

The Quitobaquito Hills rise above the international border in this 1994 survey of the arid Sonoran landscape. This cross-border map, produced by the U.S. Geological Survey and the Instituto Nacional de Estadistica Geografia e Informatica, reveals the stark terrain of the Desierto de Altar and the Sierra Los Tanques. A critical oasis in this parched environment is Quitobaquito Spring, located near the historic settlement of Quitobaquito.

Conservation boundaries dominate the American side of the line, including the Organ Pipe Cactus National Monument and the Cabeza Prieta National Wildlife Refuge. The map provides a unique dual-perspective of the region's topography, though it notes that international data for the southernmost portions was not available at the time of publication. Isolated features like Hocker Well and Cerro Blanco serve as significant landmarks for those studying the remote borderlands of Pima County.
