Avalanche problems
Avalanche Summary
Wind-drifted slopes near and above treeline are the most dangerous and likely places to trigger an avalanche. A weak snow layer buried just below the recent snowfall has been quite reactive and will grow more unstable as more snow and wind build thicker slabs throughout the day. Be careful or simply avoid slopes where you find new or drifted snow deeper than a foot. This includes previous slopes that avalanched during the Thanksgiving event and have filled back in.
Southerly-facing slopes have less weak snow near the surface and are safer options.
