Quick report
- Comment
- Observations from SAR members attending separate incident lower down in the drainage. See avalanche details. Also of note, one lone ski tourer in area today that was tip towing around the region solo. Increased caution is recommended in this region due to reactivity of a persistent weak layer in varying aspects and elevations.
