Avalanche: Turnagain
Location: Cornbiscuit North face
Wide propagating wind slab avalanche released Thur, Feb 25th midday. This slope was being actively windloaded during the day. It is believed that this slab was triggered by people along the ridge – but this is uncertain. It is possible it could have been a natural.
Slab appeared to have been small off the top of the ridge before propagating under rock features lower on slope. Width around 300′ and crown height was between 4-10″ thick. Debris looked to be around 3′ deep.
