Mattson said the objects were found underneath a band of rock and gravel that appeared to have been deposited by melting glaciers and then covered by windblown sediment...

So, these people were living under the glacier(s)? They were there before the glacier(s) formed? I don't get it.

Hi, I think someone answered while I was napping (okay, I was at work), but basically, the conventional view is that glaciers spread out, and slowly push and drag other stuff. Ordinarily that would suggest this stuff came from further north. However, the quantity found in a small area sounds more like a seasonal camp (perhaps over many years) to my uneducated ear. :')

Well, yeah. It's alot cheaper down there 'cuz you don't have the views.
