2018 Map of Blankenship Well

About this map

The international boundary between the United States of America and Estados Unidos Mexicanos cuts diagonally across this Sonoran Desert landscape, defining the southern reaches of Pima County. North of the border, the vast protected lands of the Organ Pipe Cactus National Monument dominate the terrain, characterized by a network of seasonal washes draining toward the southwest. The eastern edge of the map rises sharply into the Ajo Range and the peaks of the Sierra de Santa Rosa, providing a stark topographical contrast to the alluvial plains below. Blankenship Well stands as a solitary named human landmark in the northwest, representing the critical water infrastructure required for survival and ranching in this arid borderland environment.
