In this Saturday, Jan. 7, 2012 photo provided by the Alaska Division of Homeland Security and Emergency Management, people work to clear snow from the roof of the Cordova volunteer fire department in the fishing town of Cordova, Alaska. Residents have turned to the state to help them dig out of massive snow levels that have collapsed roofs, triggered avalanches and even covered doors, trapping some people in their homes.
