About this map

The international border between the United States and Mexico bisects this landscape, marking the transition from Santa Cruz County, Arizona, into Sonora. The northern portion is dominated by the Coronado National Forest and the Pajarita Wilderness, a region defined by the sharp rise of the Pajarita Mountains. To the south, the terrain of the Sierra Esmeralda is carved by an intricate network of drainage systems, including Arroyo el Alamo and Arroyo Real Viejo.

Evidence of historical activity is preserved in the location of Alamo Spring and the ruins of Las Juntas (Abandonada) and Los Adobes (Abandonada). These abandoned sites, along with several mines and prospects near the border, hint at a past tied to ranching and mineral exploration. Significant topographical landmarks like Picacho Alto and Cerro Santo Niño provide a sense of the complex drainage patterns that define this trans-border canyon country.
