set track from Elsay junction on Mt Seymour to the top of first pump. snowing consistently the full time, solid accumulation almost filled in our tracks by the time we returned to Brockton point. able to very easily trigger .5-1.5 slides on steep easterly aspects that seemed mainly limited due to test slope size. continued to trigger the storm slab on all aspects if steep enough with shooting cracks where the slope angle was to shallow to slide skiing on the return continued to trigger smaller slides ( 5-10 meters with a 15m run, 30cm crown) where one would expect them, but didn't experience any sympathetic releases or stepping down below the established rain/melt freeze crust.

as spoken to in the main comment section, generally reactive snow pack that any slope you though could be triggered, would be triggered, but nothing stepping down past the recent storm snow, if its steep enough regardless of aspect I bet it would release, even if small. the largest ones we didn't photograph but were on the steep easterly faces just past Brockton point
