Snow Profile

General Comments

Looking like the other big piece up high in Stairs Gulch got some wind loading yesterday. Looked like the weak layer was the old NSF. Ran to the big bend, 3,000'+. Propagated snow off the west faces as it fell. Stairs has slid twice in the last week, and has probably snowed more there than anywhere in the canyon.
