Avalanche Summary

On Saturday, there were numerous reports of human triggered avalanches up to size 2.5 running on a knife hard crust much further than expected. Human triggered avalanches are expected to be very likely throughout the weekend.

Snowpack Summary

35-40 cm of new snow is sitting on a knife hard crust/ice glaze. These storm slabs have been very reactive to human triggers. An additional 20-25 cm is expected by Sunday morning which will increase the expected size and destructive nature of the avalanches. The mid and lower snowpack are settled and well bonded with the average snowpack depth up to 300 cm at treeline.
