Went for a skin up to Hyalite Peak yesterday to check out snow conditions. We found about 8-12 inches of new snow sitting on a base at Hyalite Lake. We saw no signs of instability in the area. Small cornices were observed on the Hyalite saddle, and a hit or miss 1 inch wind slab directly below the ridge.
