UW's Dr. Carson on 18 years of mapping the Driftless, ahead of Sparta visit

If you've spent any time in local coffee shops or boutiques, you know that naming your business after "The Driftless" carries a certain amount of outdoorsy eco-prestige.  But, according to UW-Madison geologist Dr. Eric Carson, if that business is across the river in Minnesota or Iowa — they are living a lie. For the past 18 years, Dr. Carson has been mapping The Driftless. He joins ahead of his Badger Talk at 5:30 p.m. Thursday at the Sparta Free Library to tell us just exactly what that means and why it's taken two decades.  Carson talks about going county-by-county — a job we assume involves a leather notebook, a magnifying glass, and a horse with no name. Carson humors us on the tech front (turns out they use airplanes with lasers called LiDAR and drill 100-foot soil cores instead), but he breaks down the mind-blowing reality of our backyard — why the ice sheets missed us, why Lake Superior is actually a giant billion-year-old tear in the earth, and how a local river used to flow east, toward Canada, instead of west into the Mississippi River. Plus, we look at why the U.S. is facing a massive shortage of rock-nerds and why geology is actually a high-security, high-demand career. Check out the preview, and bring your questions for Carson Thursday at the Sparta Library.
