Two heavy rainstorms caused flooding and landslides in the upper valley last week, damaging infrastructure and leaving two residents temporarily trapped in their vehicle.
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.
Permafrost is ground that stays frozen year round; the permafrost in interior Alaska also has massive wedges of actual ice locked within the frozen ground. When that ice melts, the ground surface collapses and forms a sinkhole that can fill with water. Thus, a thermokarst lake is born. At first glance, Big Trail looks like any lake. But look closer and there's something disturbing the surface: bubbles.
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.
In Utqiaġvik, where the coast is eroding at some of the fastest rates in the nation, storms, flooding and thawing permafrost damage houses, roads and cultural sites. Ice forms later each year and storms are becoming longer and more severe.
Drained lake basins make up more than half of the Arctic coastal plain, but the complete drainage of a lake is rarely witnessed by people.
"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."
On June 21, 2022, when miners working on Eureka Creek in the Klondike gold fields within Trʼondëk Hwëchʼin Traditional Territory made an astonishing discovery.There, covered over by permafrost, they found the near-perfect mummified remains of a baby woolly mammoth.

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