OUTDOORS Geophysical Institute, University of Alaska Fairba One month ago, I wrote about a dramatic landscape feature in western Alaska called the Selawik Slump. The slump, caused by thawing permafrost, looks like a bomb crater leaking mud from the boreal forest into a clear northern river. There are dozens of them in northern Alaska, though none as big as the one on the Selawik River.

Thaw scars widespread across the northland

A double progressive thaw slump on both sides of the Caribou River, which flows into the Peel River in northern Yukon Territory. It is located at about the same latitude as the Selawik Slump.
