GNFAC Avalanche Advisory for Fri Jan 8, 2010

Snowpack and Avalanche Discussion

Southwest Montana has experienced the most widespread avalanche cycle in the advisory area since the Avalanche Center began 20 years ago.  Masters of the avalanche business have told me that "it looks like the continental snowpack is in full bloom" and unfortunately "the stabilization process is going to take a long time."  We have many photos and videos of recent avalanches.  Click on the links below, or visit the photo or video pages on our website.

This avalanche was triggered by a skier climbing a nearby, low angle ridge about 100ft away.  He was experiencing lots of collapsing and cracking until a collapse of the weak layer propagated across these two slide paths.  The avalanche broke 2-3 ft deep and ran well below the edge of the photo.  Photo: K.
