Workers at the end point of the trans-Alaska oil pipeline are using saws to cut up large blocks of hard-packed snow on top of oil storage tanks so they can shove the chunks off the tanks.
More than four feet (1.2 meters) of snow fell in the community of Valdez between mid-February and mid-March, causing the snow buildup that has damaged infrastructure and vented petroleum vapors into the environment, the Anchorage Daily News reported Friday.
