Edwards Plateau

The city of Del Rio, located in a southwest patch of the state on the Edwards Plateau, just across the Rio Grande from Ciudad Acuña, Mexico, has experienced a relentless wave of migration since this spring, in part because its remoteness makes it easier to cross, officials said.

Situated in a southwest patch of the state on the Edwards Plateau, the bicultural Del Rio is across the Rio Grande from Ciudad Acuña, Mexico, a way-station for migrants crossing into the United States.

The district comprises 29 counties stretching from the New Mexico border to the Brazos River valley and south to the Edwards Plateau.

In the Edwards Plateau, the rock is so porous that rivers can vanish underground, flow through the aquifer, and emerge again downstream.
