Several small caves can be reached by marked footpaths. The geological history of the area begins 10,000 years ago, when the last of the glacial meltwalters surged down the Indian River on the way to Lake Iroquois. The level of the glacial spillway was at least 14 m above that of the present water level. The tremendous flow found its way through the crevices in the limestone bedrock. The pounding gradually created large underground stream channels and caves. The action of the rushing waters in the channel created whirlpools, which captured pebbles and boulders with its abrasive spinning action. These materials were gradually ground into the limestone bedrock creating numerous „potholes” or „kettles” which can be seen along the marked trails. Text by Tony Oldham (2002).
