AST-1 course at Seymour to Mystery Peak

Ast1 course climbing Mt. Seymour to Mystery peak. We observed whumpfing sounds, shooting cracks everywhere and intentionally triggered multiple small avalanches. Observed one small natural avalanche. Inverted snowpack with ~30cm fresh snow over 5-10cm facet weak layer. Compression test on 30x30cm colum: top layer collapsed after 2-3 tabs, clear cut.
