As you picture Tawny and Takoda climbing the cliffs at Round Island,
these photos will help you imagine the challenge of climbing limestone.
This picture was taken at Mackinac Island which was formed at the same time as Round Island.
Both are part of the Niagara Escarpment. The limestone ridge stretches from
the west side of Lake Michigan in Wisconsin – all the way to the Niagara Falls.
It’s along this escarpment where many caves can be found.
Here below is a perfect example of how a cave could be located on a bluff.
Can’t you just smell the cool dampness? Wouldn’t you explore it?
Not all the climbing was difficult however.
