 Eyewitness drone footage captured the moment a house collapsed into the Mendenhall River in the Alaskan capital following glacial floods on August 5. Record flooding struck the city of Juno on Saturday after a glacial dam outburst, destroying at least one structure and prompting city officials to issue evacuation orders for residents on one street. Glacial outburst flooding happens when trapped water escapes through cracks and thinning ice dams, a phenomenon that has increased around the world as a result of climate change. The water level of Mendenhall Lake reached nearly 15 feet early August 6 morning, a three-foot rise over the previous record set in 2016, and five feet over moderate flood levels, according to the National Weather Service.
