It's a good thing our distant relatives fired up their power plants and SUV's bringing and end to the cold weather that fostered these huge glaciers 10,000 years ago.

You have to hand it to them knowing all about carbon dioxide back then before gov't paid scientists!

Already knew about this...I attended Soil Science Institute (a 4-week training session for professional soil scientists) at Washington State University this summer, and we took field trips into the Channeled Scablands to study just this event. It was fascinating (and a beautiful area). If we ever meet in person, I'll tell you all about it.

New England is like that. The ground is scoured down to granite bedrock, which is now weathered to a degree, and there are terminal morains of good size. Long Island, for example.

Interesting stuff about Washington, careful of the million years conjectures stuck in there (they are obligatory).
