1996 Map of San Miguel

About this map

San Miguel serves as a focal point in this 1996 record of the borderlands, where the international boundary between the United States and Mexico cuts across the arid floor of the Baboquivari Valley. Located within the Tohono O'odham Indian Reservation, the map highlights cultural landmarks such as the Queen of Angels Mission and smaller settlements including Haivan Vaya and Hashan Chuchg. The landscape is defined by its water management and transit infrastructure, featuring the San Miguel Tank, numerous wells, and a Corral, all essential for ranching and life in the Sonoran desert. Seasonal watercourses like Vamori Wash and El Coyote weave through the terrain, while the distinctive ridge of La Sierrita rises to the west. This survey provides an exact look at the 1990s demarcation line between Arizona and Sonora.
