Just released, the GNFAC Advisory App for iPhone is available now, and is the slickest way to get the advisory.

The snowpack is extremely unstable and avalanches are being triggered from far away.  This slide was triggered as a ski ptroller came down Sluice Box.  It ran on facets on the ground and is indicative of many slopes throughout our forecast area.  Photo: GNFAC

Bridger Bowl has a backcountry snowpack because the ski patrol has not done avalanche mitigation yet. It's wise to treat the area as such and only expose one person at a time.  In this photo five people skin up.  Thirty seconds after this pic was snapped the entire Bronco face cracked and collapsed...a close call. The snowpack does not care if you are in or out of bounds right now...it's all the same. Photo: GNFAC

This was taken this morning (Wed) at Bridger Bowl after we issued an Avalanche Warning.  Over 3 inches of SWE got piled onto a base layer of facets.  This layer is breaking very, very easily. I was able to get entire slopes to fracture and whumph with simple ski turns.  Photo: GNFAC

This avalanche in the Bridger Range illustrates the avalanche danger on even the smallest slope. Photo: Bohr

This avalanche was remotely triggered by a skier in the northern Bridger Range yesterday.  The crown is up to 5 feet deep! Faceted, weak snow underneath wind slabs are especially unstable. Photo: B. VandenBos

This avalanche was remotely triggered by a skier yesterday in the northern Bridger Range. It's not very steep. Photo: B. VandenBos

Mark dug this pit and found the bottom 10 cm to be faceted, which is the immediate stability concern.  Over 130 cm of snow is on the ground. Photo: GNFAC
