I couldn't find a key at the link. I'm curious about the dark green line that goes near the Twin Cities (curving up from the south and then east into Wisconsin). Any idea what it represents?
Could that be the Driftless Area? That is, a portion of Wisconsin, Minnesota, and neighboring states that was “never” glaciated during the Ice Ages, but instead the glaciers went around that area.
