Here is Keystone Canyon and the Lowe River in Valdez, Alaska from 1/26/2014. Due to the high temperatures in Alaska, 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 and residents are on evacuation alert. This all happens in January in Alaska when temperatures soared in the 60 range. Extreme weather events will be common, even in Alaska!
