2011 Map of Blankenship Well

About this map

The international border between the United States and Mexico bisects this arid stretch of Pima County, defining the spatial organization of the region. Life in this desert environment is anchored by the presence of water and ranching infrastructure, most notably at the Blankenship Ranch and the nearby Blankenship Well. The landscape is dominated by complex drainage patterns flowing from the eastern uplands, where the Sierra de Santa Rosa rises along the eastern margin. This map documents a sparsely populated but geographically significant transit corridor where ranching outposts serve as the primary landmarks in an otherwise open terrain of alluvial fans and desert washes.
