2022 Map of Arroyo Melado

About this map

The Rio Grande forms a prominent natural boundary in this arid landscape along the Usa and Mexico border. The terrain is defined by a series of dry washes and drainage systems that feed toward the river, including Arroyo Melado, Arroyo Chillon, and Arroyo Changas. This 2022 survey captures the modern infrastructure of Presidio County, showing the path of FM 170 as it skirts the river's edge, alongside secondary routes like Johnson Rd and Garcia Rd. Human history in this high-desert environment is represented by the Ochoa Cem, situated near the western edge of the quadrangle. Northward, the land rises toward features like Spencer Cr, illustrating a sparse settlement pattern dictated by the intense topography and limited water sources characteristic of the Big Bend region.
