2012 Map of Castolon

About this map

The Rio Grande snakes along the southern border of this desert landscape, defining the international boundary and the dramatic entrance to Santa Elena Canyon. Near the river's bend, the Castolon Historic District and Cottonwood Campground serve as focal points for human activity in this arid environment. The map details a network of seasonal drainages, such as Terlingua Cr and Alamo Cr, which cut through the terrain toward the river. Historically significant sites like Terlingua Abaja and the Coyote Cem are positioned along these watercourses, reflecting the area's long history of ranching and borderland settlement. To the north, the elevation rises toward the Rattlesnake Mountains and Peña Mtn, while the Santa Elena Canyon Lookout offers a vantage point over the deep limestone gorge that dominates the southwestern corner of the quadrangle.
