The major landforms that are part of the Great Plains of Texas are the Llano Basin, the High Plains and the Edwards Plateau. The Great Plains run from the top of the panhandle down the center west to the center of the state.
The first major landform is the High Plains, which are located in the panhandle of Texas and extend northward. The High Plains are characterized by rich, loamy soil that contains clay, sand and silt. The plains end at the Caprock Escaprment in the east.
The second major landform is the Edwards Plateau, also known as Hill Country. This plateau starts at the southern end of the High Plains and runs southeast to the Balcones Escarpment. The Edwards Plateau is characterized by its rugged terrain and impressive limestone formations.
The third landform is the Llano Basin, which lies just north of the plateau. This area is studded with reservoirs and lakes. One area is the Highland Lakes Country, which is characterized by ancient Precambrian and Paleozoic rocks and the famous Enchanted Rock granite dome.
Two other minor landforms are the Toyah Basin and the Stockton Plateau. The Toyah Basin is just west of Edwards Plateau, and the Stockton Plateau is west of Edwards Plateau and south of Toyah Basin.
