Notes

Toured into the southern Lionhead today. Yesterday’s warm weather made the snowpack more moist, and the upper snowpack was much more cohesive than in days past. Snow was glopping on skis and skins up to around 9k. I got on NE, E, and SE aspects, which were quite reactive, with more wumphs than in the last few days.

Notes

Skiers on Monday, Dec. 18 felt collapsing in the Lionhead area. They also saw an old avalanche. It likely occurred at the tail end of last week's storm. 

From obs: "Saw one small natural crown on a NE rocky outcropping around 8k, 1 foot deep and isolated. Felt a lot less collapsing than last weekend, however still found some instabilities. Notably a remote collapse that propagated around 50’ in length at around 8200’ on a NE aspect."

Wumphing in Lionhead

Went on a ski tour up Lionhead Ridge yesterday (12/18). Noted lots of sled tracks high-marking avalanche terrain on the east side of the ridge, but no major crowns. Saw one small natural crown on a NE rocky outcropping around 8k, 1 foot deep and isolated. Felt a lot less collapsing than last weekend, however still found some instabilities. Notably a remote collapse that propagated around 50’ in length at around 8200’ on a NE aspect.
