The Yakutia region in Central Siberia, where the Lena River is located, is an exceptional point of interest to study this type of erosion based on its record low temperatures and extreme thickness of permafrost. During the winter when water level is low, a thick sheet of ice forms on top of the Lena River, that is sometimes as much as 2m thick. Seasonal floods caused by rapid snowmelt and irregular storms then break the ice apart in the summer, exposing the banks of the river to the power of erosion. There are two stages to this process: the"
