Comments
The persistent slab problem is always in the back of our minds and there was evidence of previous persistent slab avalanches in terrain visited and viewed today (High Ivory and Mt. Baldy). Current structure in the core (upper LCC and BCC) puts the Feb 2/3rd near surface facets down about a meter, and any others at least twice as deep on northerly facing slopes. That said, repeater paths such as Cardiac Ridge and 2 Dogs were avoided by our group today due to the potential presence of this issue.
Photos below:
1. Cornice growth above 2 Dogs
2. Transport along AF/LCC ridgeline
3. Transport on High Ivory
4. Transport on Mid Ivory (erased tracks)
5. Previous crown from natural slab release below High Ivory (note loose dry avalanches off of ridge)
6. Ski penetration was less than 10cm, which made for great, supportable skiing at mid elevations out of the wind
7. Upper Cardiff- lots of surface evidence of wind saltation in the bowl.
