Warming temps, new snow and wind are the perfect recipe for fresh slab formation.

Continue to re-evaluate conditions as you gain elevation and transition into open terrain.




Avalanche Summary

Thursday; there was a close call when a skier triggered a size 1.5 avalanche on the S/SW side of Cheops and was able to self arrest; and a skier triggered slab avalanche on a S facing moraine.

Wednesday there was a widespread natural cycle in the highway corridor, triggered by wind.

Tuesday, there was a skier triggered avalanche on the W Side of Cheops.

Early in the week, there were a few skier triggered avalanches reported.

*All skier triggered avalanches failed on a suncrust.

Snowpack Summary

15-25cms of recent storm snow overlies variable wind slabs/wind effect in open terrain, and settling facetted snow in sheltered areas below treeline.

A sun crust, down 40-55cm, and most prominent at treeline, has been the failure plane for isolated large skier triggered avalanches recently.

Below 2100m there is decomposing crust down 70-80cm (from Dec 5th/6th).

The Dec 1 surface hoar layer is down 90-120cm and is decomposing.
