Points saillants

Low Ratings but seriously questionable riding conditions.

On the other hand, Ice climbs in the region are in great shape. Low ratings are a poor excuse for not carrying a transceiver, shovel and probe!

Snowpack Summary

Variable surfaces including temp/rain crust, wind press and loose snow sit above the recently developing November rain crust which may go as high as 2200m. Total snow pack height in alpine is around 45-85 cm. Wind pressed/scoured features to wind slabs in lee features in the high alpine. Cross loaded gulleys may threaten ice climbs from above.

Avalanche Summary

Previous strong winds transported variable storm snow through the high alpine peaks and ridge tops. Hazard can be expected to increase in isolated areas where wind effect and loading is visible. No natural activity observed or reported in the forecast region.
