Avalanche: Hatcher Pass
Location: Southeast aspect of Hatch peak
I was part of a 3 person group. Toured up the sunny side of Hatch peak south shoulder and then a ridge walk to the summit. No red flags observed during tour. We skied the southwest face giving the gully that slid a wide birth. We transitioned at the bottom of the valley and observed second skier in another group remote trigger a large slab avalanche that propagated 100 plus feet into and across gully.
Avalanche Details
2nd skier in a different party remote triggered large slab avalanche. Skier said he heard and felt collapsing and slab broke 15 feet below skier and propagated across gully in picture. Debris field settle toward the bottom of gully. About 500-600 feet of vertical slide.
