1985 Map of Guadalupe Canyon

About this map

The Spring of Contention marks a remote junction where the Arizona and New Mexico borders meet at the international boundary with Sonora, Mexico. This mid-1980s provisional study provides a detailed view of the rugged transborder terrain, where topographic features like Baker Canyon and Guadalupe Canyon define the landscape. Small settlements and ranching outposts such as Puerta Blanca, El Papalotito, and El Jalisco are scattered across the southern half of the quadrangle in Sonora, connected by a network of unimproved roads and a Pack Trail. The map illustrates a sparse and arid environment characterized by isolated water sources and complex relief, including C. Puerta Blanca and the drainage of Cajon Bonito. It offers a clear look at the jurisdictional complexity of the Peloncillo Mountains area before modern border infrastructure altered the corridor.
