Written Report:
We toured out to the SE slopes of Three Finger Jack to check out and ski the NE facing slopes towards Booth Lake. Travel was in blizzard conditions and worsened as we neared the South ridge with winds around 30-40 mph. Snow was being transported easily and cornices were building quickly and were sensitive. The lee slopes were wind loaded but untouched powder was found further away from the ridges. The unconsolidated powder had little cohesion and was not particularly slabby when we first arrived but as the temps rose the upper snow was heavier and showing slab potential. It was difficult to carry momentum on slopes near or below 30 degrees which made skiing less than ideal for the storm slab risk that was present. We stayed away from slopes steeper than that. On our last skin up and out we saw a D1 natural that recently was triggered by what looked like a cornice fracture.
