2011 Map of Cipriano Pass

About this map

Butler Mountains anchor the southwestern corner of this landscape in Yuma County, marking a stark transition in the desert terrain. The arid environment is defined by a series of drainage patterns and ephemeral washes that cut through the valley floor, eventually funneling toward the namesake Cipriano Pass in the east. This 2011 survey by the U.S. Geological Survey details a largely undeveloped portion of the Arizona desert, where natural topography remains the primary feature. The isolation of the area is underscored by the lack of named settlements or major infrastructure, leaving only the primary geological landmarks to guide travel through this corner of the Sonoran desert.
