We rode far and wide around Cooke City and only saw 2 avalanches: the one on Henderson Bench that Alex saw on Thursday, and another shallower one on Miller Ridge that broke just below the new snow. All-in-all, stability is improving. Near the bottom of the snowpack facets from December could still fracture and avalanche, but this instability is not widespread. #gnfacobs

We visited a large avalanche on Henderson Mountain that broke yesterday afternoon, Feb. 15 2019. We do not expect widespread avalanches like this near #cookecity, but it is wise to avoid heavily wind loaded slopes where these are possible, especially during heavy loading from snow and wind. The more likely type of avalanche is fresh drifts of snow 1-2' thick on recently wind loaded slopes. video at https://youtu.be/oOjaEWyCVdI and http://www.mtavalanche.com #gnfacobs

Check out the latest updates from the GNFAC: a new forecaster, and new and updated pages to the website.

Doug wrote an article for the upcoming Avalanche Review about our education efforts in Cooke City and the the Centennials (ID and MT).

After last season's two snowmobiler avalanche fatalities on Reas Peak in the Centennial Range we created a webpage so riders could get good, relevant information regarding snowpack and avalanches.
