2019 Map of Las Conchas

About this map

Ruidosa stands as the primary settlement in this corner of Presidio County, situated where the high desert terrain meets the fertile strip of the Rio Grande. The landscape is defined by the sharp transition from the river valley to the uplift of Pinto Canyon, with the international boundary between the United States of America and Estados Unidos Mexicanos winding along the river's path. Access through this remote borderland is provided by FM 170, which parallels the water, and Pinto Canyon Rd branching eastward toward the mountains. The drainage network, including Arroyo Escondido and Arroyo Baviza, illustrates the seasonal water patterns that have shaped the local ranching and agricultural history. This survey captures the traditional land use and infrastructure of the Big Bend region, where isolated outposts and river crossings have long dictated the pace of life.
