text:  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. They radiocarbon dated them, and they found that they had grown up 1,000 years ago. And this, again, was under the glacier. So the evidence shows that where today we have a glacier, the Mendenhall Glacier, 1,000 years ago we had a forest in this area.
