Texas’ Gulf Coastal Plains are the western extension of the coastal plain extending from the Atlantic Ocean to beyond the Rio Grande. Its characteristic rolling to hilly surface covered with a heavy growth of pine and hardwoods extends into East Texas. In the increasingly arid west, however, its forests become secondary in nature, consisting largely of post oaks and, farther west, prairies and brushlands.
The interior limit of the Gulf Coastal Plains in Texas is the line of the Balcones Fault and Escarpment. This geologic fault or shearing of underground strata extends eastward from a point on the Rio Grande near Del Rio. It extends to the northwestern part of Bexar County, where it turns northeastward and extends through Comal, Hays, and Travis counties, intersecting the Colorado River immediately north of Austin. The fault line is a single, definite geologic feature, accompanied by a line of southward- and eastward-facing hills.
