General Comments

Hair trigger wind loads going with an easy kick. Most being hard wind slabs. Running fast on buried surface hoar on top of the new snow from Monday night/Tuesday. Some up to 3' thick. Could only find these on North slopes. All South through SE slopes were wind scoured. Found many wind pockets on North slopes in treed areas going with a ski cut. Hard Slabs had One Finger + hardness with 4 finger or fist at the bed surface. In some places could see the Surface Hoar with the naked eye.
