I hiked the trails in
on Manitoulin Island.
This park has some of the best examples of alvar habitat, these large, exposed areas of limestone.
Some still bear the scrape marks from the glaciers.

The limestone along the shore has been shaped by Lake Huron |
 |
Many fossilized corals are exposed in the limestone |

Here's a large chain coral |
