"Parts of North America was covered in glaciers two miles thick and Yellowstone is about a mile high, so all but the tallest peak was covered in ice. "

At the peak, maybe. At the peak, 90% of the present park was covered in ice. But that was 20000 BCE. By 10000 BCE, the time period in question, things had changed quite a bit. Most of the ice had either melted or was in full retreat. The mountains had mainly snow pack and ice fields, although there were a few glaciers left.

So the artifact found is similar to the find of Oesti. It got deposited in snow that later turned to ice and has just now melted out. It isn't like it was trapped in a glacier.
