2019 Map of Santana Mesa

About this map

Santana Mesa dominates the northern bank of the Rio Grande in this isolated reach of Presidio County, marking the international border between the United States and Mexico. The landscape is defined by deep incisions like Canyon Colorado and Canyon Madera, which drain toward the river through an arid, high-desert environment. Human presence is concentrated along the river corridor via FM 170, while the interior remains accessible primarily through routes like the Rancherias Loop.
