from P Diegel: At about 10:30am, 9,500 ft, just clear of the trees on Gobblers Shoulder: Isolated 3 columns, 2 failing easily about 50 cm deep with secondary failure about 40 cm deep and one that took a lot more prying. ECT 18 (see video) no propagation, but pulled out easily, failing in steps at about the same depths. on our 2nd run at about 11:15, fog rolled in with rime. Riding conditions were smooth and consistent in about 20 cm fresh somewhat dense creamy snow, rapidly getting damp and denser. Wind was swirling and erratic. We stuck to the lower angle treed shoulder out of respect for the stout slab and potential slide consequences.
T Diegel - on our 3rd climb we glimpsed through the fog what we thought was a smallish slide coming down Alan's Gully. Another party at the trailhead at the end of the day confirmed our sighting and said that the crown seemed to be sort of jagged. Unsure of the trigger, but another party of two did apparently ride their boards down an adjacent slope, but again the viz was such that we couldn't see for sure. Based on past experience with that area, I'd guess it was in the 38 degree range, NW facing, around 10k feet.
