Snowpack Summary

Alpine is either stripped of snow completely or offers a variety of wind affected surfaces. Surface faceting continues with cooler temperatures. Strong mid-pack overlies generally supportive basal layers. Decomposing surface hoar is found down 40cm to 80cm in isolated sheltered locations, in the very southern parts of the park.

Avalanche Summary

Field team reports no new avalanche activity observed.
