Avalanche Summary

No natural avalanches observed today but poor visibility. Two size 2 persistent slab avalanches triggered remotely by field team today.

Snowpack Summary

Up to 70 cm of storm snow overlies a facet and crust combo which exists in more sheltered areas. This overlies a melt freeze crust complex in the alpine and at treeline. Areas close to the divide have the best snow coverage.
