About this map

Oro Blanco and the surrounding high desert canyonlands define the border country of Santa Cruz and Pima counties during the mid-1990s. This survey illustrates the complex intersection of the United States of America Estados Unidos Mexicanos boundary as it cuts through the Atascosa Mountains and Pajarito Mountains. The landscape is a mix of protected lands and mining history, with the Morning Star Mine situated among rugged summits like Atascosa Peak and Montana Peak.

Conservation areas including the Buenos Aires National Wildlife Refuge and Pajarita Wilderness flank the international line, while the presence of U.S. Customs at Sasabe marks the primary point of transit. Drainages such as Sycamore Canyon and Bear Valley provide critical watershed context for this arid region, showing the natural corridors that have historically dictated movement through the mountain passes of the Coronado National Forest.
