Ice-rich permafrost bluff in northern Alaska
By Pacific Coastal and Marine Science Center
September 2007 (approx.)
Detailed Description
Ice-rich permafrost bluff photographed in early September 2007, during a period of mild, persistent easterly winds. Despite the absence of westerly storms, traditionally believed to drive coastal erosion in this region, waves were undermining the bluff at this time.
