Comments

Avy debris from approx 20 loose-wet point sluff avalanches noted between Near Treeline to Alpine elevations on N/NE/E faces this AM. Size ranges from 1-2.5 depending on terrain (gullies were worst). Start zones were usually exposed rock or steep slopes. Snow is isothermal and very wet from 950-1150m. A weak freeze-thaw crust (2-4cm) was observed between 1150-1350m that was unable to hold the weight of a boot/human (likely higher elevations too but unable to verify). Crust rapidly disappeared between 0630-0800 due to solar warming, leading to human-triggered rollerballs and size 1 sluffs. Overnight temps never dropped below 11c, temp inversion present. Bailed on mountaineering objective due to Considerable avy risk. Use extreme caution, even in pre-dawn hours!
