Notes
From e-mail: "The wind picked up after noon today and we observed moderate amounts of blowing snow at and above tree line. My climbing partner and I were able to trigger a small loaded pocket between slot corner and curtains, 30 deg, NNW aspect, which failed 6 inches deep and 15 ft wide on diurnal facets (old snow surface). The slab didn't move much due to the stubborn angle..."
