2014 Map of Blankenship Well

About this map

Organ Pipe Cactus National Monument dominates the eastern landscape of this desert corridor, where the high ridges of the Ajo Range and Sierra de Santa Rosa rise above the basin floor. The map highlights a critical stretch of the international border between the United States and Mexico, cutting across the southern portion of Pima County. This survey is focused on an arid, largely undeveloped environment where water sources like Blankenship Well were vital markers in the vast expanse of southwestern Arizona. The topography is defined by the stark transition from the alluvial fans and desert washes to the steep, craggy slopes of the eastern mountains.
