SComments:
We intentionally triggered several small storm slabs. They were all on steep convex rollovers. Crowns were typically 4-6in deep and they ran very well for how shallow the slides were. They seemed to fail on the interface from last night's (Sat night's) new snow.Observed Avalanches

SComments:
We observed ~10 natural storm slab avalanches with 6in crowns near Sluskin Falls and Edith's Creek. They were typically D1.5 slides. They were observed around 11:30 am and looked very fresh.Signs of Unstable Snow
Did you see shooting cracks?
Yes, WidespreadDid you experience collapsing or whumpfing?
NoObservations
Weather: Generally light snow becoming moderate in the afternoon. We did have one very nice break in the precipitation where the sun even tried to make an appearance. Winds were typically light and variable with blowing snow only in very exposed areas.
Snowpack: Several inter-storm layers exist in the recent snow. The storm total looks to be about 12in in most places. Small slopes, skin track tests, shovel tilt tests, and hand pits/hand shears all highlighted a layer about 4-6in below the surface. This corresponds with the natural and triggered avalanches. We also saw failures and cracking on the 2/3 interface. No weak persistent grains were found at either layer.
