The Amistad Dam and Coahuila, Mexico
The northern part of the Mexican state of Coahuila, formally Coahuila de Zaragoza, is visible here.
Coahuila accounts for a 512 kilometers (318 mi) stretch of the U.S. – Mexico border, adjacent to the U.S. state of Texas along the course of the Rio Grande (Río Bravo del Norte).
The Sierra Madre Oriental runs northwest to southeast through the state, and the higher elevations are home to the Sierra Madre Oriental pine-oak forests. Part of the range is visible in the lower right quadrant.
East of the range, the land slopes gently toward the Rio Grande, and is drained by several rivers, including the Salado and its tributary the Sabinas.
Part of the Amistad National Recreation Area, USA, can be seen in the top right corner. It includes the area around the Amistad Reservoir at the confluence of the Rio Grande River, the Devils River, and the Pecos River. The Amistad Reservoir, created by the Amistad Dam in 1969, is located on the border with Mexico.
