Avalanche Forecast

No recent avalanche observations from the field.

On November 28th a natural wind slab size 2 was reported and the interesting thing is that it scrubbed to the ground and ran quite far.

Upper Snowpack: 5-15 cm of new low-density snow adding 20 to 30 cm of snow from the past week. In windy, alpine areas it may have been hardened into a slab, but generally it's soft and faceting (turning into sugar).

Lower Snowpack: Below the recent snow are a couple of surface hoar layers or extra faceted snow. But generally, it doesn't really matter because it's all mostly soft facets (in representative places that are out of the wind near treeline)

There isn't much holding everything together other than wind hardening. In most places the lack of structure doesn't support slab avalanche (only loose dry) but in wind-loaded lee slopes where the snowpack is thicker and more cohesive the situation could be different.

In the alpine, snowpack depths range from 50-150 cm. At treeline there is around 50-100 cm. Below treeline is thin and scratchy. At all elevations there are many early season hazards like rocks and stumps.

• Be especially cautious as you transition into wind affected terrain.
• Avoid terrain traps such as gullies and cliffs where the consequence of any avalanche could be serious.
