Sally Younger is a science historian and writer from the glacially uproarious state of Wisconsin. Like most indigenous cheeseheads, she grew up with the Ice Age National Scenic Trail in her backyard and didn't know it. Whether by boot, blade, or back road -- she has now experienced all 1,000 miles of theTrail. From Great Lake fishing towns to frac-sand mining operations, she's tried to document how the Earth's latest great climate change continues to define a way of life here, a dozen millenia after the glaciers retreated.
In the words of one passing snowshoer, the Ice Age Trail is “the best trek you’ve never heard of.” And we’ve tried to experience it as the glaciers that carved it would have intended: in the off season.
