    Within the past week, there have been occasional reports of skier remote and explosive triggered slabs on the Oct 26 crust and facet layer. Avoid steep terrain where a stiffer, more cohesive slab exists over the weak snow at the base of the snowpack.

Avalanche Summary

Puzzle Peak had a large rockfall event. Glide-cracks on the top indicate the possibility of further rockfall. Outside our expertise, but maybe avoid the toe for a while.

Weather Forecast

Slowly cooling temps and maybe some outflow on Saturday. Colder still on Saturday (teens), but not viciously so.

Snowpack Summary

The October 26 crust is found ~10-30 cm above the ground. A generally facetted snowpack averages 40-85 cm at 2200m across the region.
