General Comments

With good visibility in the early AM, I saw at least two deeper HS's that were triggered by LS slides sometime yesterday morning. One of them was in Slide Canyon at 9700', E facing, in Shot 12. The other was in the Bearclaw path at about the same elevation. Each of them were relatively small pockets, (50' wide) but they are interesting because of their depth (2.5'-3' deep). We haven't seen anything this deep in a while and it indicates the pockety nature of the deep slab issues. Below is the pocket in Slide Canyon.
