Accompany Director of Education Tom Finley and Senior Naturalist Don Quintenz for a leisurely stroll along the shore of our Great Lake to learn about the geologic history of both the lake, and the beautiful and diverse rocks that litter its shore. Learn why most of the rocks on the beach are of Silurian age and how this related to the regional geology. he many fossils that etch the surfaces of the dolomitic rocks tell stories of ancient life forms that lived in tropical seas. The surrounding landscape includes the Nipissing terrace and a more ancient bluff that were formed as the Great Lakes rose and fell with the opening and closing of outlets to the sea. We’ll consult historic maps of the Great lakes to see how the glacier’s advances and retreats caused this to happen.
