Large Deep Slab Avalanche at Big Sky

Big Sky Ski Patrol triggered a large deep slab avalanche during control work this morning, with a crown depth up to 10 feet deep. From the e-mail: "This is generally one of our most heavily wind loaded areas on the mountain with any wind with a westerly component.   It ran on a combo of ground and an ice crust that was sitting in a recessed area, probably leftover October snow.  Crown depth ranged from 10’ near the cornice but quickly tapered to an average of 3-5’." -BSSP
