The Llano Uplift Region of Texas

    This area is also known as the "Central Mineral Region" of Texas.

    The Llano Uplift region is a fragile ecosystem.  As stewards of the land, Texans should do all they can to protect the terrain of the Llano Uplift region from pollution, erosion, and destruction.  Surface pollution seeps into our precious aquifers, and thus affects our drinking water.

    Although it is hard, granite is brittle, and thus fractures and cracks easily.  Even the weight of an average human being can cause sheets of granite to break off of the exposed granite surfaces in the Llano Uplift area.  Despite granite having a reputation of being a durable material, it erodes more easily than the more-prevalent limestone surrounding it.

    For example, in his book, Geo Texas, geologist Eric R. Swanson, professor at University of Texas in San Antonio, states on page 29 of his geology text:

    "Although granite is a hard rock, in the semi-arid Central Texas climate it is less resistant to erosion than limestone.  As a result, the Central Mineral Region forms a basin floored by metamorphic rock and granite and rimmed by Paleozoic and Cretaceous limestone formations of the North-Central Plains and the Edwards Plateau.  The basin floor is studded with what locally are called mountains, impassive granite domes or ridges of Paleozoic limestone rising to heights of 400 to 600 feet."

There is only one Texas!  Take care of it!
