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.
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 heavy rains and high water from storm Murdok today and Monday are contributing to the erosion of the old landfill and river bank.
Community gravel source and old dump site threated by erosion.
The collapse was documented with drone imagery as was a permafrost rebound signature in the river water.
Noatak has lost 19' of river bank since May 19th. Now the road to the community gravel source is failing.
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 multinational company that operates the Red Dog Mine in Northwest Alaska says that thawing permafrost linked to global warming has forced it to spend nearly $20 million to manage its water storage and discharge.
Staircases are separating from building and utility poles leaning.
The ground under the new road is developing a sink hole and affecting the foundation of the adjacent house.
Ground settling is causing a wide range of impacts in Noatak, including to the water treatment plant. But are there benchmarks to monitor the changes in the water plant?
Noatak site experiencing thawing and subsidence.
The issue of erosion is not new to Noatak cemetery. The old cemetery was located near the Noatak's airstrip, but in 1993, the spring breakup caused 30 feet of erosion adjacent to the cemetery. Flooding during the fall of 1994 further threatened the site, so residents relocated 200 graves to the north side of town.
