 from Southeast Alaska University. And in the ice cave, they found tree stumps. And these stumps are up to a foot in diameter, and they still had roots in the ground, and they found many of these. The radiocarbon dated them, and they found that they had grown up a thousand years ago. And this, again, was under the glacier. So the evidence shows that where today we have a glacier, the Mendenhall Glacier, a thousand years ago we had a forest in this area.
