The Balcones Escarpment. It is geology’s most fateful mark upon the surface of Texas, a bulwark of cracked and weathered rock that extends in a pronounced arc from Waco to Del Rio. It is the Balcones that creates the Hill Country, that sets the stage for the Edwards Plateau and the High Plains beyond. Above the mass of limestone there is only a veneer of soil, and the country is hard, craggy, and scenic—cowboy country.
