Adrienne McGill, manager of the Begich, Boggs Visitor Center in the Chugach National Forest, holds up photos of Portage Glacier that show the changes from 1998 to 2003. The visitor center, seen here on July 18, has scrapbooks at the front desk with photographs of retreating Portage Glacier that were taken over the years. McGill said many return visitors comment on the drastic changes they've noticed. (Photo by Yereth Rosen/Alaska Beacon)
