1981 Map of Pajarito Peak

About this map

Pajarito Peak dominates the northern skyline of this international boundary sheet, standing as a prominent landmark within the Coronado National Forest. This 1981 survey documents the rugged canyon country along the border of Arizona and Sonora, where the landscape is marked by a complex network of water management features including Walker Dam, Calabasas Tank, and Bull Spring. The map provides a rare look at both sides of the frontier, with the northern half detailing early mining operations such as the Sunset Mine and White Oak Mine. To the south in Mexico, the terrain transitions into a series of smaller named settlements and ranch sites, such as La Bellotosa, El Reculador, and Los Nogales (Chicón). The proximity of these outposts to the international boundary illustrates the historical ranching and mineral prospecting that defined this arid corridor during the late 20th century.
