The creation of Natural Tunnel began more than a million years ago in the early glacial period when groundwater bearing carbonic acid percolated through crevices and slowly dissolved surrounding limestone and dolomite bedrock. Then, what is now Stock Creek was probably diverted underground to continue carving the tunnel slowly over many centuries. The walls of the tunnel show evidence of prehistoric life, and many fossils can be found in the creek bed and on tunnel walls.
