Remotely triggered from flat ground 50 feet from the base of the slope. The avalanche broke along a cliff band at the top of the hill and ran about 200 feet where it piled about 15’ deep in a terrain trap gully at the base of the slope.
Collapses had been happening all day so we knew how unstable the snow was but was surprised to see such a large avalanche triggered from a long ways away.
