Central Texas Natural History

The Edward’s Plateau encompasses the hill country ecoregion of Central Texas. The Balcones escarpment, forming a semicircle from southwest to northeast surrounding central Texas, forms the Edward’s plateau to the west, which ends to the west and north with more uplifted terrain. The limestone bedrock of this plateau was formed in the Cretaceous by shallow sea deposits. The plateau uplifted in the Miocene while the Gulf Coast region to the east subsided. Subsequent erosion formed the karst topography characteristic of the area today, with abundant hills, creeks, springs, and caves. The Edward’s aquifer roughly follows the western border of the Balcones escarpment and several other aquifers are found in the plateau.
