Cooke City, 2021-03-13 From email on 3/12/21: "...silver creek up to the saddle of Meridian in the NP yesterday. ... It was on the S aspect at 9,500ft of the shoulder that takes you up to the steep trees W of Meridian. It must have occurred in the last 24-48hrs due to not much snow had fallen since the avalanche occurred. It ran out down into the trees below. ... The crown looks to be over a foot deep, and the length must have been 50ft" Photo: P. Whitmire Link to Avalanche Details |

Out of Advisory Area, 2021-03-07 From obs 3/6/21: "Observed several smallish avalanches in Yellowstone National Park today. The interesting thing about this one is the bison track that goes into the slide. No telling if the avalanche was triggered by the bison, but the shallow snowpack is about 1/2 faceted, so maybe it was remotely triggered." Photo: J. Logan Link to Avalanche Details |

Northern Gallatin, 2021-03-07 From obs 3/6/21: "Two large natural avalanches in Maid of the Mist Basin. One of them ran on the east face of Arden Peak (Peak 10,201) which propagated across the entire face. Could have been triggered by a cornice fall then stepped down to deeper layers. The second was on the NE face of the peak Fat Maid and Skinny Maid come from. Also propagated across the entire slope. Crown height between 6'-8' in most places." Timing of these slides is unknown. Probably in the last week, but maybe older. Photo: S. Enloe Link to Avalanche Details |

Cooke City, 2021-03-07 From obs on 3/6/21: "Small slab avalanche with snowmobile highmark tracks. They do not appear to be related, since there are no tracks into or out of the slide. Approximate coordinates 45 4.313 x 109 55.380" Photo: R. Taylor Link to Avalanche Details |

Northern Madison, 2021-03-06 We saw these recent wet loose avalanches on 3/6/21. SW aspect, 9,100'. They likely ran during above freezing temperatures between 3/3 and 3/5. Photo: GNFAC Link to Avalanche Details |

Northern Madison, 2021-03-06 From obs: "While touring above the canyon this morning, I noticed a very recent wet slide (would guess this incident occurred yesterday afternoon, March 4th). This was a skier triggered slide on a E aspect at an elevation of 7200. This slide was roughly 50 feet wide and ran about 50 feet, I estimated this crown to be 2-3 feet deep, slid all the way to the ground. This occurred below a steep roller." Photo: T.
