Comments
This avalanche was reported a couple of times since it was originally viewed on Monday, Nov 14th.
Mark White and I took a closer look of it today. Same deal as all the rest, facets from October were the weak layer. The interesting thing here is, as far as we could tell, it was a natural avalanche which makes it one of very few from the Sunday slide cycle. There were no ski tracks anywhere along the ridge to indicate it may have been human triggered. I speculate it ran late in the storm on Sunday.
