Valdez Alaska: Massive Avalanche and ice dam in Keystone Canyon

This clip shows a flyover of Keystone Canyon and the Lowe River, 1/26/2014. A glacier sized avalanche has blocked the river. An ice lake has formed, currently at an estimated depth of 60 feet and growing. The Richardson Highway is flooded and the town of Valdez cut off from road access. There is some concern as to when and how the lake will release and downstream residents are on evacuation alert. Courtesy Vertical Solutions
