Avalanche danger scale ratings

GENERAL AVALANCHE ADVISORY

The snow pack remains unstable. Very large slab avalanches are likely to be triggered by humans and can still release naturally. Yesterday, skiers witnessed a naturally released avalanche run full track on Teewinot Mountain. A snowmobiler triggered a large slab avalanche north of Teton Pass and a skier outside of the boundary of Snow King Mountain remotely triggered a large slab avalanche. Similar events are likely today. Sunshine and warming temperatures will be increasing the likelihood for these dangerous slides to release. The consequences of being caught in one of these slabs would be severe. Expert terrain analysis skills and conservative terrain choices are essential for safe travel in avalanche terrain.

DESCRIPTION

Dense slabs up to six feet in depth lie upon a persistent weak layer of faceted snow. These slabs could be triggered on a variety of aspects by the weight of a single person, release naturally or release after they have been crossed by multiple skiers or riders. At the lower elevations smaller pockets of dense slab up to two feet in depth could be human triggered on steep avalanche prone slopes.
