Balcones Trail

Balcones Trail

Detailed Description


This view near the entrance to the Balconies Caves shows basically how the cavern forms from large boulders undercut by the stream. Unlike most caverns that form from the dissolution of limestone underground, the underground passages at the Pinnacles form from the combined effects of stream incision and the collapse of large blocks and rubble from the narrow canyon walls to cover the passage of the stream.
