He says thawing permafrost is endangering sites and artifacts dating back thousands of years.
"Instead of having the archaeological remains and the houses and whatnot being stable, they're actually eroding out of the cliff face," he said.

Friesen says researchers need to act quickly and prioritize which sites should be excavated before their contents are destroyed.
