About this map

Organ Pipe Cactus National Monument dominates the northern landscape of this Pima County survey, where the Puerto Blanco Mountains rise above the arid expanse of La Abra Plain. The international border between the United States of America and Mexico serves as the central focal point, bisecting the terrain where Arizona and Sonora meet. This 1990s record captures a complex cross-border geography, detailing several Mexican settlements such as Santo Domingo, Josefa Ortiz de Dominguez, and Morelia that sit just south of the line.

Industrial and recreational history is marked by the Milton Mine and its connecting Milton Mine Trail, while vital desert water sources like Pozo Salado Well and Aguajita Wash underscore the environmental challenges of the region. The map provides a detailed view of the infrastructure along the boundary, including Puerto Blanco Drive and the various wilderness protections like the Organ Pipe Cactus Wilderness that preserve this unique Sonoran Desert ecosystem.
