Northern Madison, 2023-02-25 From email 2/24/23: "Came across this very large cornice that appeared to have broken naturally sometime in the past 24 hours. Saw a few others that had broken recently throughout our tour, but none as large as this." E. Heiman Link to Avalanche Details |

Northern Madison, 2023-02-25 From email 2/24/23: "Triggered a small 2’ deep wind slab in new snow this afternoon. NNE aspect 9,500’, approximately 38° slope. Riding was excellent on all high North facing slopes and this was the only sign of instability we saw all day. Wind was howling on the way out, lots of snow coming out of the trees and transporting at ridge tops." Link to Avalanche Details |

Cooke City, 2023-02-25 Large avalanche in Sheep Creek from 2/21: "slide in the photo looked to be an average of about 2-4' deep (6' deep in places) and about 800-1000' wide, spanning across lots of different terrain features. I also noticed that the main south facing slide path off of Miller Mountain avalanched very large as well. (the same avalanche path where the snowbiker was killed last winter) I couldn't see the crown, but the debris ran to the valley bottom and appears to have flattened a large stand of mature timber."

Cooke City, 2023-02-23 In Cooke City a large storm dropped 4.5" of snow water equivalent (4 feet of snow) and there were a few avalanches reported during and immediately after the storm. We saw one large avalanche on a south facing slope on Meridian, and a smaller wind-loaded slope that avalanched on Mt. Abundance (photo). We saw no other activity. Our concern is the interface between the old snow and new snow. The avalanche activity seemed to break here and on slopes with a wind-load it's worth being extra careful. |

Cooke City, 2023-02-22 Photos of some recent natural avalanches near Cooke City today attached. All of the slides observed appeared to just involve new snow from the Feb. 20-21 storm. (occuring on all aspects, but primarily on NE aspects) New snow: generally about 50-80cms of settled new snow from Feb. 20-21. Quite a bit of collapsing experienced today while breaking trail, particularly in the lower elevations. Snowpit attached from a SE aspect at 8500'. HS: 170. ECTP15- 55cms down, at new/old interface.
