St Marks Avalanche

Skied Christmas Gulley, good snow, but higher up small wind slabs, and evidence of slabs becoming cohesive due to wind activity.

Avalanche across the St Marks Trail. Crown line is variable in depth from 120cm to 50cms. A very large amount of debris. An older Douglas Fir appears to have been felled along with several smaller trees. The creek is filled with debris. Further south there is debris throughout the trees. Hard to tell if it is the same avalanche. Looks several days old, probably from the last warming period.
