Fault or Balcones Fault Zone is an area of largely normal faulting [1] in the U.S. state of Texas that runs roughly from the southwest part of the state near Del Rio to the north-central region near Dallas [2] along Interstate 35. The Balcones Fault zone is made up of many smaller features, including normal faults, grabens, and horsts. [3]
5.35% [1] Protected. 2.26% [1] The Edwards Plateau is a geographic region forming the crossroads of Central, South and West Texas, United States. It is named in honor of Haden Edwards. [2] It is bounded by the Balcones Fault to the south and east; the Llano Uplift and the Llano Estacado to the north; and the Pecos River and Chihuahuan Desert to ...
Edwards and Trinity Aquifers map. The Edwards Aquifer is one of the most prolific artesian aquifers in the world. [2] Located on the eastern edge of the Edwards Plateau in the U.S. state of Texas, it is the source of drinking water for two million people, and is the primary water supply for agriculture and industry in the aquifer's region.
General geology. Texas is approximately bisected by a series of faults that trend southwest to northeast across the state, from the area of Uvalde to Texarkana. South and east of these faults, the surface exposures consist mostly of Cenozoic sandstone and shale strata that grow progressively younger toward the coast, indicative of a regression ...
Set in the scenic hills and canyons typical of the Texas Hill Country, the preserve lies about ten miles north of the Balcones escarpment and within the Balcones Fault Zone. The elevation ranges from approximately 1,280 to 2,000 feet (390 to 610 m). The local Woodard Cave Fault runs through the property on a general east-west line.

Llano Uplift. Precambrian and Paleozoic inlier surrounded by Cretaceous uplands. The Llano Uplift is a geologically ancient, low geologic dome that is about 90 miles (140 km) in diameter and located mostly in Llano, Mason, San Saba, Gillespie, and Blanco counties, Texas. It consists of an island-like exposure of Precambrian igneous and ...
The area was vaguely defined and shifted over time but generally was described as bordered to the south by the Balcones Fault, just north of San Antonio, Texas, continuing north along the Cross Timbers to encompass a northern area that included the Cimarron River and the upper Arkansas River east of the Rocky Mountains.
