Current
Conditions:
Another dusting of snow
overnight. It is still cold up there on the Skyline today and that is the
dominant weather player right now. The 6-8” of snow that has fallen over the
skyline in the last couple of days will make for great conditions on all
aspects as the snow has stayed nice and cold with a minimum of sun. Dress
warmly, and expect dynamite conditions of powder on a supportable base.

Avalanche
Conditions: (Click here for the International
Avalanche Danger Scale)
Friday we were able to observe some monster cornice failures up on the Skyline. Some of the chunks are as big as a bus. The snow on the ground is generally stable, except for the fact that we have some weak snow buried under the new snow from this past week. Time heals all wounds they say, and the majority of the new snow has been sitting on this weak layer for a few days now. The snow from Saturday night was a small enough amount to keep the avalanche activity down and these cold temperatures will also help lock the new snow in place.
For today the BOTTOM LINE is going to be MODERATE up on the Skyline. Be especially careful of large overhanging cornices and areas that have developed shallow wind slabs on North-Easterly aspects. These wind slabs will be not be widespread and will be most prevalent on upper elevation ridgelines or any other areas with exposure to wind.
Have fun out
