A year after the Merbok Storm: Impacts on Cemetery
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.

Rain continues to impact Noatak River
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.

Severe Erosion in Newtok
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.
Newtok, Alaska, United States

Storm Merbok causes erosion to cemetary
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.

Sudden lake draining event
"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."

Bank erosion exposing old landfill contents
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.
Chris Dankmeyer, Paul Walton, Tom Wolforth, Jeffrey Luther, Joy Britt

Erosion at Cape Blossom
"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."
Kotzebue, Alaska, United States

Summer thawing impacts on utility poles and shoreline
Thawing permafrost and erosion is resulting in the loss of infrastructure in Newtok. These images show impacts on utility poles, and the shoreline.
Newtok, Alaska, United States

High water this summer changes travel on Noatak River
"This year we had a lot more rain than other years, we used to be able to get on our ATVs and travel 10-12 miles upriver. I haven't seen or heard of anyone using ATVs to travel upriver this year. I think the breakthrough channel has a lot to do with us not being able to travel on ATVs. I see a lot of my favorite ATV fishing spots washed away from the highwater."

Bank erosion putting community water wells and transmission line in danger
Community Water System at Risk: Extreme precipitation throughout the summer and sustained high water has resulted in erosion of the location for the water transmission line and Noatak's two water wells.
