More detailed information about the avalanche: 

Today we observed 3 different avalanches that we felt were around size 3. The slide in the positives bowl and the slide in the fern lake area both slid during the storm sometime and the debris/crown is somewhat covered by new snow. The slide in the Hemlock trees was fresh this morning on a NE aspect at approx 9500 ft. We also observed a large whumph in the trees above the double eagle resort at approx 9000 ft, a crack shot some 150 yards across the top of the whole slope and the snow settling was visible to the naked eye.
