Photo: Rock slide

This photo released by the Alaska Department of Transportation and Public Facility shows cleanup crews removing rock and debris Tuesday on Portage Glacier Highway near Girdwood. Crews were working to mitigate additional slides. An April 11 rock slide left a 300-foot pile of rubble as high as 30 feet on the road, blocking the travel to and from Whittier.
