Notes
Leaving Cooke on 12/3 we saw many natural avalanches that likely broke on 12/2. Estimate more than 50% of slopes facing north, 8,000-9,000' had crowns 2-4' deep. The largest on Old Man Ray's below republic was R3-D2.5, 400+' wide, 1,000' vertical. There were a couple, possibly larger, on Thunderer in the park, but low light made them difficult to confirm.
