If an arrow shaft was found from about 1500 years ago, does that imply there probably wasn't ice there at the time? Or were people hunting on the ice then?

without a single picture of any of the artifacts

That made me very frustrated! Here's the proper article, with actual pictures: https://www.smithsonianmag.com/smart-news/2000-artifacts-pul...

Thanks for the link. Aside from the OP article's basic regurgitation of prior (perhaps stale - I couldn't read it either being behind a "sign-in wall"), the Smithsonian author clearly didn't view it as a race against time and human-induced climate change, but merely an unexpected windfall for researchers:

"There are countless negative impacts of the changing climate, but the recovery of these artifacts could be an unexpected positive. Our uncertain climate future may inadvertently help researchers learn more about our past."

Cant read this article, Medium shows me to signup for an account.

That always pops up for me, but I can just close it by clicking outside the box or clicking the x in the top right. Do those not work for you?

The latter. Anything under the glacier would be pulverised into dust (the glaciers even carve out their own valleys). These artefacts must have started up above the ice (on top or down a crack), so the people would have been hunting on the ice or maybe travelling across it.
