Is this a sign of more to come? Land changes raises questions about possible causes.
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.
The Merbok storm of 2022 impacted the Old Russian Cemetery in Saint Michael. This cemetery was created in the 1830s when the northernmost outpost of the Russian American Company was established in that village. People were interred in that cemetery for about 100 years. The cemetery is on a 30 foot high bluff overlooking the bay.
River erosion is impacting the road and requiring the replacement of health infrastructure.
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.
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.
A site visit to Newtok on September 30, shows severe erosion from impacts of storm (typhoon Merbok). The images show both severe permafrost melt and river erosion.
The erosion of the Old Russian Cemetery from the impacts of the storm Merbokis also an unfinished process. The earth is actively moving, falling onto the beach bit by bit and sometimes in large chunks every day, to reach a state of stabilization after the storm.
The heavy rains and high water from storm Murdok today and Monday are contributing to the erosion of the old landfill and river bank.
The aftermath of Typhoon Merbok left fuel tanks floating and home flooded, but locals also saw an opportunity.
"The event occurred on June 29th, on our native allotment near Kotzebue (Illivak). We left home in the morning and when we came back around 8:00 PM in the evening the whole lake had drained! It looked like it was blown up with dynamite."
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 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."
Thawing permafrost and erosion is resulting in the loss of infrastructure in Newtok. These images show impacts on utility poles, and the shoreline.
