1985 Map of Deepwell Ranch

About this map

Allen Flat serves as a central basin in this arid Cochise County landscape, bounded by the prominent rises of the Johnny Lyon Hills to the southwest and the Little Dragoon Mountains to the southeast. The area is defined by its intermittent drainage patterns, with Tres Alamos Wash and Palomas Wash cutting through the terrain. The namesake Deepwell Ranch stands as a primary point of human activity, supported by essential water infrastructure like Mesa Tank and Sunnybrook Tank. This 1985 survey captures the region's transition from open range toward modern utility development, evidenced by the infrastructure of a Trans Line Steel Tower and several Trans Line Wooden Poles that traverse the basin. The map provides a detailed record of the topography and land use in this part of Arizona just before the close of the twentieth century.
