1985 Map of San Pedro Ranch

About this map

Johnny Lyon Hills and the Little Dragoon Mountains dominate this high-desert landscape in southeastern Arizona, where the terrain is defined by a network of seasonal drainage systems. The presence of the San Pedro Ranch indicates the long-standing cattle ranching tradition of Cochise County, situated among the undulating foothills and prominent summits like Mae West Peaks. This 1985 provisional survey captures the intersection of traditional land use and modern infrastructure, shown through the various trans lines and a pipeline that cross the arid basin. Water management and natural flow are highlighted by the prominent Tres Alamos Wash and Sheep Wash, which receive runoff from several major canyons including Texas Canyon and Granite Canyon. These features illustrate the complex topography that has historically challenged and shaped movement through this region of the American Southwest.
