Route & General Observations

Two remotely triggered avalanches on Tincan today around 2:15pm, on┬áSouth and North aspects of CFR ridge. No one was caught. I spoke with a group in the parking area who said they had experienced collapsing, especially when all three of them were grouped together. They didn’t witness the slide, but submitted first photo below.

Update: another group in the area reported they heard the large collapse and witnessed the avalanche occur.

Visibility was good in Turnagain Pass and was able to get eyes on road side mountains. Sunburst SW face, as reported by a party on Dec.4, avalanched mid-storm. Pete’s South looked suspect of natural mid storm avalanche, but couldn’t confirm. Debris was not obvious. Seattle Ridge SE face was wind loaded with lots of cross loaded gullies. No obvious avalanches post storm.
