Lulu to Goose Lake

Sledded over Lulu to wilderness boundary today, then toured up around Goose Lake. Observed numerous human and sled triggered avalanches. All on S aspects in the 9 to 10k range, depths around 30 cm, D1R2. Dug at Goose Lake, found surface hoar buried 35cm down, ECTN. I suspect the surface hoar was involved in the avalanche events we observed based on crown depths. Seems to only be reactive on S aspects? Sled tracks everywhere. Also may have seen the avalanche mentioned in the advisory... it’s E of Huckleberry not N but close enough! Looks like it could have jacked up a sled but still only D1.
