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
