The border area lying between the south-east and south-west parts of America have a uniqueness to become mentioned as a distinct region. It is known as the Texas Hill Country and that is for specific reasons. It lies on the south-east part of the Edwards Plateau that forms big habitats on its grasslands and caves. The characters of the flora and fauna of these habitats have influenced the bounties of Texas Hill Country also. It combines the geographical, ecological, and climatic features of both the sides lying near it.
Just like the plateau terrain, the region has a hilly terrain that consists of numerous caves, and hills made of limestone and granite. This topography is geographically called karst topography and has created many marvelous and natural structures in the deep and interior caves. If the hills reach to a maximum of 500 feet, the nearby Packsaddle Mountain rises higher above up to 800 feet. This mountain is a treat to the tourists as well as the geologists who are working to unearth many historical stories lying beneath each layer of rock. If gold formed the center of old stories, tribal fights dominated the later historical years. For the tourists, the saddle-shaped rocks give the most intriguing sight. Next is the Llano Uplift which consists of higher terrains and granite domes made up of igneous and metamorphic rocks. It has a diameter of about 90 miles and extends from the Colorado River to the Llano River. You can get the famous pink granite blocks from the Granite Mountain rock quarries or enjoy the Enchanted Rock which is the largest of its type in the US. All in all, it is a great site to know how beautiful granite domes can get and how bountiful you can become with pink granites.
The next geological wonder here is the Balcones Fault Zone in the south-west part. It is actually made up of many smaller faults, depressed faults known as grabens and raised faults known as horsts. Along the Colorado River, the Covert Park or Mount Bonnell Fault offers great tourist points and forms a part of the Balcones Fault. This fault zone is also significant for the fact that the neighbouring cities of Austin, New Braunfels and San Marcos are fed by the water of the springs coming from the Edwards Aquifer located on the Edwards Plateau. The country hill is a combination of great geological formations without many human interventions, but is highly useful for the human settlements here, apart from serving as tourist destinations.
