Avalanche Summary

Watch for newly drifted slabs of snow at upper elevations. Shooting cracks or a smooth-looking snow surface, that is harder than sheltered areas, are indications of a problem.

On shady slopes sheltered from the wind, the upper snowpack is losing cohesion. You can trigger long-running loose avalanches, also known as sluffs, in continuously steep terrain. With another foot of snow on Friday night, loose avalanches can gain enough volume to bury you, especially if combined with a terrain trap.
