The Smithsonian has an interesting article on artifacts and bodies emerging from melting glaciers.
As Glaciers Retreat, They Give up the Bodies and Artifacts They Swallowed
Now, thanks largely to decades of global warming, the Presena glacier running through the battleground is slowly melting away. And with that melting the remains of the White War are slowly emerging. Remarkably well-kept artifacts have been streaming down with the melting water of the glacier since the early 90s
They don’t seem to get it. Just like the P-38s on Greenland , for something to emerge from the ice would imply to me that things are returning to where they were when the artifacts/bodies were deposited on the ice.
Artifacts and bodies ended up on the ice. Snow fell. The snow turned to ice and entombed the artifacts. After 100 or 5,000 years it is now as warm as it was long ago.
