Edwards Plateau, Limestone plateau in Central Texas, United States.
The Edwards Plateau is a limestone highland in Central Texas featuring extensive cave systems, sinkholes, and natural springs that feed major Texas rivers. The terrain varies from rocky outcrops to open grassland areas that define the landscape across the region.
This highland formed roughly 100 million years ago during the Cretaceous Period when ocean waters covered the region and deposited layers of sandstone, limestone, and dolomite. As the waters retreated, these rock layers remained and gradually shaped the elevated terrain visible today.
Indigenous peoples including the Jumano and Coahuiltecan inhabited this land for centuries before the arrival of Lipan and Mescalero Apaches. Today, archaeological sites and local stories keep these early populations present in the region's identity.
The thin soil and rocky terrain make large-scale farming impractical, so ranchers use the land primarily for cattle, sheep, and goat grazing. Visitors should prepare for rough ground conditions and wear sturdy footwear, especially when exploring the cave systems and sinkholes.
Bracken Cave near San Antonio harbors one of the world's largest colonies of Mexican free-tailed bats. Millions of these mammals pour out of the cave entrance at dusk, creating one of the region's most remarkable wildlife displays.
