This Sept. 7, 2010 picture provided by the U.S. Geological Survey shows walruses on the barrier island beaches near Point Lay, Alaska. Tens of thousands of walruses have come ashore in northwest Alaska because the sea ice they normally rest on has melted. Federal scientists say this massive move to shore by walruses is unusual in the United States. ASSOCIATED PRESS VIA U.S. GEOLOGICAL SURVEY
