General Avalanche Advisory
The general avalanche hazard is considerable above an elevation of 8,000 feet and is moderate below that elevation. Dangerous slab avalanches could be triggered by snowmachines and skiers. In areas that have exhibited poor snow structure for several months large to very large persistent slab avalanches could be triggered by the weight of a single person or after a slope has been crossed multiple times by snowmachines. Slab avalanches could be triggered by humans in wind loaded areas, involving snow from the recent storm cycle or they could fail on well-developed weak layers comprised of faceted snow that formed during prolonged dry periods earlier in the season. Careful snowpack evaluation is necessary to understand the weak snowpack and conservative decision making is essential to avoid having accidents that are likely to have severe consequences.

DESCRIPTION

Surface slabs formed during the most recent storm cycle continue to be a potential hazard on steep, wind-loaded slopes at the higher elevations. These slabs could be triggered by the weight of a single person and could be one to three feet deep.

DESCRIPTION

In steep terrain persistent slab avalanches could be triggered by humans on buried layers of faceted snow. These slabs could be triggered by a single person who crosses a weak spot on a slope, by larger triggers like snowmachines or by the initiation of a wind slab. These large to very large slab avalanches could be 3 to 5 feet deep at the mid and upper elevations or one to three feet deep at the lower elevations.
