About this map

The Continental Divide winds through the high desert peaks of Hidalgo County in the early 1980s, marking a rugged intersection along the United States of America - Estados Unidos Mexicanos international border. This borderland landscape is defined by the San Luis Mountains and the Sierra San Luis, where deep drainage features like Lang Canyon and Cañon San Luis carve through the arid terrain. Human presence is tied to vital water sources such as Blackjack Tank and Larson Tank, which supported isolated settlements and outposts in this transborder region. Along the Mexican side of the line, small clusters like Los Lamentos, El Valle, and Agua Blanca appear as faint dots against the vast contours. The map captures a specific moment when these remote desert locations were documented through combined aerial photography and field checks, recording the topography of El Diablo and the southernmost reaches of New Mexico before modern shifts in regional infrastructure.
