Slump 002 (IMAGE)
Caption
Noatak National Preserve in Alaska: This thaw slump initiated prior to 2007 and has continuously expanded over time. At present, it is 150 meters (492 feet) in diameter and 2-3 meters (~6-10 feet) deep at its deepest point. Sparsely vegetated areas are recently disturbed, whereas dense clusters of willows can be seen across the slump and vibrant yellow forbs (Mammoth flowers) are recolonizing the terrain only a few years after the disturbance.
