Surface conditions and riding quality were better than expected: the rain crust is buried a few inches deep, soft and thin here, and slabs are stiff and supportive (1F). They range from 45 cm on windward and BTL features to 70 cm+ on leeward features NTL. Weak layers are consistently large-grained (2mm+), fist hard, and show minimal signs of strengthening/rounding. Slabs appear to be smaller and less continuous on windward aspects ATL, but with more trigger points. I only poked briefly into a SE aspect NTL and found a very thick crust (15 to 20 cm) capping the drought facets, and that was on a 20 degree slope; I would expect an even thicker crust on steeper terrain. .
On sled, I noticed 3 collapses/shooting cracks: one was a slope scale collapse on a leeward, east to northeast facing feature at 11,900' that I triggered while crossing an eroded patch of snow near the ridgeline. The other two were smaller collapses (20-30' wide) on windward aspects (NW near treeline and W below treeline), where slabs were thinner and softer. See photos for pits and descriptions.
