LEO Member Jeffrey Luther has been documenting erosion along the Noatak River for many years. His drone footage this spring captures new bank erosion features and icicle formations.
Heavy rains have elevated river levels throughout August and September. High water continues to erode the river bank in the community. The photos show a tree that was 22 feet from the edge is know 3 feet. Total erosion has reached 91 ft. by old landfill and new mark shows 112 ft. marker.
Kivalina residents report cracks on the sides of the recently built evacuation road which connects the village to the storm refuge site and the school. The team with the Alaska Department of Transportation & Public Facilities plans to visit the village and assess the damages at the end of August.
This post is an update on the river erosion situation in Noatak, where a new channel is being cut by the Noatak River.
Permafrost thaw in Noatak is causing the condition of the grave site to degrade. A trench has formed and crosses are tipping over.

The collapse was documented with drone imagery as was a permafrost rebound signature in the river water.

A fisherman was coming home from fishing last night and noticed (what he thought was) a coffin sticking out of the old gravesite above one of the markers I used to measure erosion with last summer. It turned out to not be a coffin, but rather an old air duct or metal meat trailer.
I'm guessing all the rain we received during summer of 2021 created the trench.
"The sea level rise and wind is making this happen because it is really vulnerable. We are always really amazed every time we go out there with the change, and pieces of earth the size of a house falling over."
