Edwards Plateau: Balcones Canyonlands
built 608 days ago
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. This concentration of effort is due to two related factors, ecology/hydrology and modern development.

The drainage flows directly across the scarp line and has cut great canyons backward into the Edwards Plateau. The depth and precipitous character of these increase in the streams successively encountered as one goes westward. The portions of these streams lying within the area of the plateau before they cross the fault line have cut their channels approximately down to the level of the Rio Grande Plain. Their bocas in many places cut the scarp line into a series of tongue like salients projecting toward the plain, and the line is further diversified by plateau remnants in the form of outlying buttes. The position of the scarp is determined by a complex dislocation of the rocks, the Balcones fault, which will be described in a subsequent section (p. 258).

Friedrich Wilderness Park is situated on the Balcones Escarpment where the land rises abruptly from he Gulf Coast Plains to the Edwards Plateau. An area of dense faulting known as the Balcones Fault Zone marks the boundary between the Plains and the Plateau.
