The eastern Edwards Plateau and the intertwined eastern Balcones Canyonlands have been the focus of intense archeological investigation since James E. Pearce began excavating sites in the Austin area around 1919. The western portion remains a relatively flat elevated plateau whereas the eastern portion known as the Hill Country is deeply eroded. Topography is characterized by plateaus and limestone hills , incised by deep valleys and canyons with Falling from the clouds on the vast sparsely populated area to the northwest known as the Edwards Plateau, it is filtered and purified by Nature's own processes as it finds its way through cracks and fissures in the Edwards Limestone rock. theYear=theYear+1900 Anglo settlement brought German farming communities, and adventurous livestock ranchers which have been since identified with Texas. Physiographically, it is an erosional region with thin soil over beveled Comanchean limestone exposures that extend as limestone beds to constitute the underpinning of the High Plains, lying above the Permian and Triassic beds and beneath the more recent unconsolidated Pliocene and Pleistocene deposits, the latter forming the constructional surface of the High Plains. in part of the Edwards Plateau.

These hills and surrounding valleys of the Hill Country are a direct result of limestone washing away. Map of the Edwards Plateau Texas Parks & Wildlife Department Because of the elevation drop off at the edge of the Edwards Plateau as well as its location between the dry western plains and the moist prairies and woods to the east, average rainfall varies widely from 23 inches per year to 35 inches per year.
