Notes

Jan. 9, About 45 minutes after we left a snowpit on Mt. Abundance, from a couple miles away, we saw a 4-6' deep avalanche that happened since we had been there, about 1000' up the ridge from our snowpit m. This slide was either natural or remote triggered by riders about 1000' away who were there after we were.

Notes

Went snowmobiling north of Cooke City today near Round Lake. I saw about 20cm of new snow. I also saw some avalanches. There were a couple on E Henderson, one that I think happened today, a few on E Sheep Mountain, some shallower avalanches, and plenty of loose dry snow moving around in the steeps. Here are some photos. Some looked like they were from today, some are older. Lots of evidence of wind from the past day or so.
