Permafrost thaw is causing trail in Golovin to erode.
Observation by Carol Oliver:
It appears to be getting larger and is along the trail to Camp Kitchavik. There is an odor of noxious gases being released, smells like sulfur, and is it coming from the clay?
Comments from LEO Editors:
The UAF Geophysical Institute's Permafrost Laboratory is a great resource for permafrost data in the circumpolar region of the globe as it relates to climate change and human disturbance. Visit the Permafrost Laboratory webpage and read their published report, "Snow, Water, Ice and Permafrost in the Arctic (SWIPA) 2017" for more information.
