Avalanche Summary

No notable recent avalanches have been reported in the region. In neighboring regions, several natural wet loose and wet slab avalanches were reported to size 2.5 on Monday.

Glide cracks are reported in steep rocky terrain. Glide slab avalanches are particularly hard to forecast so it is safest to avoid traveling in these areas.
