2021 Map of Blankenship Well

About this map

Organ Pipe Cactus National Monument dominates the northern portion of this borderland survey, where the arid expanse of the Sonoyta Valley meets the international boundary. The terrain is defined by the sharp rise of the Ajo Range and the Sierra de Santa Rosa in the east, providing a stark topographical contrast to the broad alluvial plains below. This map captures the modern state of the United States and Mexico border, marked clearly as United States of America Estados Unidos Mexicanos. Human presence is sparse, centered primarily on infrastructure like East Fenceline Rd and the isolated Blankenship Well. The lack of dense development underscores the remote character of this Pima County landscape, where the primary features are natural drainages and protected federal lands rather than established townships.
