Avalanche

D 0.5 Loose snow avalanches initiating on steep rock ran and looked to trigger two N-R1- D1.5-O. These slides looked to have shallow debris piles but the avalanches ran about 600'. They were on a north aspect and both approximately 12800' . They looked to have propagated about 10 to 20m across and ran sometime late in the storm with an inch of new snow covering the debris.
