1948 Map of Sunnyside SW

About this map

The high desert borderlands of Cochise County are documented here during the late 1940s, highlighting the rugged livestock operations and topographic isolation along the international boundary. Remote homesteads such as McNab Ranch and Lone Mountain Ranch sit at the southern edge of the Coronado National Forest, where steep drainage systems like Sunnyside Canyon and Bodie Canyon define the landscape. This 1948 survey is particularly significant for its precise marking of the United States-Mexico border, including survey markers like Mon 106 5211 along the line between Arizona and Sonora. The terrain transitions from the heights of Campini Mesa to the drainage of Joaquin Creek, revealing a landscape where water sources were critical, evidenced by the presence of a lone Windmill amidst the complex elevation contours of the Huachuca Peak vicinity.
