Comments
Naturally triggered D2 avalanche with sizeable crown. Did not get closer to investigate, nor did we dig a snowpit. I am guessing it failed on the buried PWL from November only because of the size of crown. Failed beneath a significant slope convexity.
Comments
Another long time observer sent in this picture taken from Cornice Ridge as the crown became visible with clearing this morning....(Wolford)
