Massive Avalanche and ice dam in Keystone Canyon | Mallemaroking

I don’t usually work on this sort of thing, but very recently I have been writing about hazards caused by the cryosphere. A major hazard is of course the avalanche – whether ice, snow, or a mixture.

This video was posted on You tube (with the tag line “Courtesy Vertical Solutions”), and it shows the impact of a snow and ice avalanche on the Alaskan road network on the 26 January 2014.

I tweeted it yesterday and the glaciologist Mauri Pelto replied

@icey_mark That is Richardson Highway that is flooded now, if this releases as one would expect in a torrent, the highway will fair worse.

I’ll try to remember to keep an eye online to see the outcome.
