Comments
Was looking at this slide from above the lakes. Seemed pretty fresh and I don't see it on the avy list yet. Thinking maybe a natural from the period of North winds during the last storm. Guessing based on my pit today that the failure was on the interface of the heavy wet snow and the drier snow from after the cold front passage on Friday, or possibly some NSF from prior to the storm. Tough to really tell from across the way. Graupel seemed to be a player in the failure planes in my pit. This slide released directly underneath the White Cliffs and took out all of Martha's Bowl underneath Double Dogleg, running down into the choke above the lake. Will likely be a good candidate to repeat later on.
