Southern Yukon Permafrost Collapse

In 2007 when we filmed permafrost thaw in Alaska, we had to ask the ice scientists at University of Alaska Fairbanks where it was. It was there and pretty bad, but just nowhere near as common as in 2018. It didn’t line the roads, but darned near in southeastern Alaska, up the Dalton Highway, and in Southern Yukon and Northern British Columbia. This is in Southern Yukon on the Alaska Highway.
