Through squinted eyes, or looking into the distance, the Texas Hill Country landscape has a soft, round quality. The hills and ridges rise and fall with an eye-pleasing gracefulness. But on a closer look, the landscape is quite rugged. There is more rough limestone rock than there is soil. The native trees, plants and wildlife are well adapted to the extremely hot summers that lasts for months on end. Most plants are able to survive through heat and drought. Year round, the Texas Hill Country is a fascinating area to study the natural environment.
