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.

Alaska's newest lakes are belching methane
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 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.
