Sea To Sky

Cold with light NW wind throughout the day. Significant wind affect from strong NW winds in the wake of the storm. Lots of reverse loading the suspected cause of a natural size 1.5 windslab on the climbers left horseshoe of the glacier at ridge crest. This entrained a lot of loose snow and ran almost 150m. We ascended the shoulder but rode the climbers right horseshoe of the glacier. It was a mix of wind board in the top 5cm and powder once in the line. Ok riding but not great. Also observed a size 1 slab avalanche (suspected windslab, ~10cm crown, 15-20m wide) on a NE aspect between the rocks coming out of ninth hole towards Decker lake, and another size 1 loose dry on a steep SE slope coming down to Decker lake. Both skier triggered. 15-20cm light powder on mellow SW aspects on our way out near Decker meadows. However, S-SW aspects >25deg started to have a sun crust forming on them around 3:15pm
