Snow Profile

General Comments

I intentionally triggered a small test slope above this slope which triggered the larger avalanche.

It initially failed on the weak layer visible below the recent wind/snow event and stepped down to the problematic surface hoar layer

This is the deepest, wind loaded part of the crown.

General Comments 2

General Comments 3

The two weak layers are obvious here.

General Comments 4

I also remotely triggered this slide from the ridge further west. Just new snow here.
