Notes

From obs "We rode up Lulu Pass at 8AM on 3/11/23 and saw the debris from a large D2.5-3 avalanche on the SE face of Fisher Mtn. Similar slide path to the large avalanche on Fisher earlier this season."

From GNFAC 3/12: "Today we rode north of Cooke City and looked at recent natural and Human-triggered avalanches. The slide on Fisher Mtn. was very large and appeared up to 10 feet deep. It had much more volume in the debris than the slide that was triggered on this same path in December."
