Edwards Plateau

A region of west-central Texas which is bounded by the Balcones Fault to the south and east, the Llano Uplift and the plains region to the north, and the Pecos River to the west. It consists primarily of limestone, with elevations ranging between 100 ft. and 3000 ft. The Plateau lacks any deep soil suitable for agriculture and is primarily a grazing region. Several rivers cross the region, which generally flow to the south and east through the Texas Hill Country toward the Gulf of Mexico; however, permanent surface water supplies are sparse throughout the area.
