[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 the west. [3]
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.
The Llano River (/ ˈ l æ n oʊ / LAN-oh) is a tributary of the Colorado River, about 105 miles (169 km) long, in Texas in the United States. [1] It drains part of the Edwards Plateau in Texas Hill Country northwest of Austin.
The Edwards Group is a geologic group in Texas. It preserves fossils dating back to the Cretaceous period . A stratigraphic column at the Mount Bonnell Fault location starts with the Lower Cretaceous Trinity Group overlain by the Edwards Group.
Inner Space Cavern lies within limestone and dolomite rocks of the Edwards Group formed during the Cretaceous period. [1] Following the formation of the Balcones Fault, a series of vertical fractures through the Edwards Formations allowed ground water to freely move through the limestone marking the beginning of the cavern's formation.
Terrain is hilly on the field itself, with some steep canyon walls and numerous mesas. The region is along the edge of the Edwards Plateau. Elevations range from 2,300 feet (700 m) along the Pecos River to over 2,800 feet (850 m) on the highest mesas.

There are five main types of mountains: volcanic, fold, plateau, fault-block, and dome. A more detailed classification useful on a local scale predates plate tectonics and adds to these categories. [ 6 ]
