General Comments

Intentionally triggered two slides in Scotties on the ridge west of the summit. First was cornice drop, second was ski cut. Both propagated and ran. Neither caught nor carried a person (skier made it to island of safety on the ski cut). Both failed on new snow/old snow interface. Depth varied from 50 to over 100 cm in depth and in both cases the soft slab was the result of wind loading. All photos are of the second, ski cut triggered slide.
