Comments
Dug a quick pit on a similar aspect, a bit more protected, off the ridge at the pass. Looking to see how the old was holding the new. Results from the pit, got a moderate shear at the interface, about 8+ of new but the new snow was not cohesive and it lacked any sort of energy. Up the ridge things were more exposed to the nuking winds setting up more of a wind slab off the ridge. Remote trigger from about 40 ft away. A lot touchier then we expected. Visibility was poor but it looked there might have been a sympathetic release down not up the ridge right around the telephone poles. Too far to see what it slid on, definitely an obvious density change in the storm snow, made riding interesting.
