The Edwards Plateau, also referred to as the ‘hill country’, is a vast region comprised of limestone uplands, rolling hills, steep canyons, and hidden springs that are supplied by the Edwards Aquifer.
The Edwards Plateau formed during the Cretaceous Period (~100 million years ago) and originally existed as shallow marine bodies that left behind deposits of sandstone, limestone, shales, and dolomites. Over long periods of time, this region underwent ‘tectonic uplift’, a process where part of the Earth’s crust becomes raised due to the shifting movement of tectonic plates. On the eastern edge of the Edwards Plateau lies the Balcones Fault Zone or Escarpment, a region of drastic topographical change and long term erosion that created the landscapes we can see today.
