Unprecedented flooding hits Alaska capital Juneau, leaving at least 100 homes damaged. The flooding occurred when a nearby glacier retreated, creating a basin that fills with rainwater and snowmelt each summer. The water then forces its way under or around the ice dam created by the Mendenhall Glacier, entering Mendenhall Lake and eventually reaching the Mendenhall River.
