Thanks!
Confidence
Problems
Cornices
Cornice failures have been observed this past week. The activity is likely from a combination of strong spring solar input, new cornice growth and cold temperatures making them susceptible to failing. They are not triggering slopes below.
- Avoid slopes when the solar radiation is strong, especially if they have large cornices overhead.
- Minimize exposure to corniced features.
Aspects: All aspects.
Elevations: Alpine.
