General Bulletin, Wednesday, December 11, 2019

The recent warm-up and rain settled our snowpack which is now refrozen in steep terrain. Be aware of the potential for a long, sliding fall into rocks or trees if you venture out to hike or climb. It’s next to impossible to self-arrest on bulletproof, refrozen snow so choose your route carefully. Also, strong winds may quickly build small areas of unstable wind slab with surprisingly small amounts of new fallen snow due to fall this week. Look for these unstable wind slabs in steep gullies, behind and beneath steep terrain features and anywhere that is sheltered from the wind. The rain soaked and now frozen snow surface often bonds poorly to new snow. Even small avalanches can be a problem, particularly with the refrozen, icy snowpack that exists where self arrest or escape can be difficult.
