Exploring the Border of the Ice Age: The Ice Age Trail

Global warming raises increasing concern these days, and, in the scope of earth's history, it is not the first time. Our global climate has changed radically and cyclically over the last million years. The glacial ice of the last Ice Age pushed down into Wisconsin and left tons of debris there as it receded. 

The National Ice Age Scenic Trail traces the border of the incursion of ice from the north into North America. Extending from Interstate State Part on the Minnesota border to Potawatomi State Park on Lake Michigan, it winds for over 1,000 miles through Wisconsin. (See map at right)

Largely maintained by volunteers, the trail offers a great destination for  hiking and sports enthusiasts, a nature conservation haven, and it also helps tell the story of the last Ice Age in Wisconsin.

The trail is roughly about as old as I am, but I only discovered it for the first time this month when I visited one county park that lies on the path.

I will share that story in my next post. Meanwhile, you can follow these links to learn more about the Ice Age Trail:

Really interesting post.

If you do even a small amount of reading on climate, you can take on the rightist radio commentators.

Would love to walk that trail. Sadly down here in South Carolina the average Joe is so ignorant of science that it will take sea levels rising up to the steps of the state capitol before they even consider global warming.

good stuff.... I have hiked different sections through the years up in the Chequamegon forest, down in the Kettle Morraine and at Potawatomi Park. Hope you are having a good time!

I hope you waved as you were in Wisconsin! We live close to the start at the Western edge of this trail system, just a few miles from Interstate State Park on the St. Croix River.
Looking forward to reading about your adventure.

We've driven across the continent in the past week + and I've been marveling all the way at how the landscape was carved by the ice and water as the caps melted. To think that all of Canada and a lot of the US was covered by glaciers nearly 2 miles high is pretty sobering as you drive through the Columbia River Gorge and the St. Lawrence on the other side.

What's really fascinating is that the last glacial maximum was only 18,000 years ago and the last major episode of melting was 8,500 years ago. That means it was all happening while modern humans were on the scene. Cool, eh?

Thanks to you all who read and especially you who commented, sharing my enthusiasm for the Ice Age Trail resource. I can't believe I had never heard of it. I think it is a really cool idea that is quite an asset to Wisconsin.

I've been learning lots about the ice ages and climate changes on such TV channels and History and Discovery. I wonder if any right-wingers do the same?
