2019 Map of Castolon OE S
USGS Topo · Published 2019About this map
The Rio Grande carves a winding path through the northern corner of this landscape, forming the international boundary between the United States of America and Mexico. A portion of Big Bend National Park is visible along the river's edge, highlighting a transition from the protected federal lands in Brewster County, Texas, to the state of Chihuahua. The terrain is characterized by a complex network of drainage patterns and ephemeral washes that lead toward the river valley, illustrating the arid hydrology of the Trans-Pecos region. This 2019 survey documents the remote borderlands where the natural course of the river remains the primary geographic marker between two nations.
