Na wind slab with propagation

We saw a size 2.5 Na windslab above Fraser chutes with impressive propagation (500m), cross loaded by the NE winds on a convex roll. A few small wind slabs on S aspects popped off on steep features overnight. We dug on NE and S aspects at 1200m, finding hard SC results down 60-65, stubborn to propagate on ECT results. This is our storm snow sitting on a variety of surfaces. The day was cold, a steady -22 with light winds from NE. The sledding remains incredible with not much traffic.
