General Comments

Saw this glide avalanche, must have happened just after the sun came up this morning. 99.9% sure it wasn't there on the way up, and the debris was very fresh. A piece of a looming slab on rock released to the ground this morning, approximately the lowest 30 feet of it and it was approximately 70' wide.

Other than this glide, there was minor cracking and collapsing as I approached the ridge between O'sullivan and Twin Peaks, but it was mostly manageable. Snow on descent was about 24" of new, still about 8-9% density, at 10am
