Comments
This Natural avalanche off Cardiac Ridge either happened late Wednesday night or early Thursday morning, debris was only covered buy a small amount of new snow, crown was probably a couple hundred feet, spreading out to maybe 400ft at the widest point. ran full track to the flats at the bottom, about 1500ft vertical. Looks to have run on facets at the ground, the starting zone was stripped to the dirt.
Photos: full deal, and the crown.
