Quick report

Cracking
isolated

New snow amounts of just an inch at the car and up to 8" as I climbed higher. I did not feel any slabs with my poles while climbing except for one very isolated feature on the climbers ridge. 7800ft NW 40deg. I decided to investigate and upon walking on it 6-10ft cracks shot out, and with one jump the slab broke 20x20feet and slid down hill 20ft, probably would have ran more if terrain allowed. However continuing the climb neither my partner or I observed any more wind slabs. I would assume this specific slab to have been created during yesterday's wind before the snow. We proceeded to the summit with no other instabilities observed except a small dry loose release that appeared to be triggered by a small cornice break. Very minor loose sluffs while descending first lap. Second lap we skied slightly steeper terrain under the hanging face and released a couple of larger sluffs that may have been slightly slab like but visibility was rapidly decline and could not see more than 100ft.
