About this map

Bob Thompson Peak anchors the northwestern corner of this Cochise County landscape, where the high elevations of the Huachuca Mountains descend into the high desert plains. Managed as part of the Coronado National Forest, this rugged terrain is cut by Montezuma Canyon before flattening toward the international boundary. Along the southern edge, the line between the United States and Mexico is clearly delineated, marking the border between Arizona and Sonora.

The eastern half of the map is dominated by the seasonal flow of the San Pedro River, which supported a network of mid-century cattle operations. Ranching history is well-documented through labels for the Smith Ranch, Zaleski Ranch, and Montezuma Ranch. Infrastructure for water management is evident in the Pumping Substation and Water Gate, reflecting the critical importance of irrigation and livestock watering in this arid environment. Traces of earlier occupation appear as Ruins near the mountain foothills.
