This slide is a good example of slopes where avalanches can be triggered. Ones that are steeper than 35 degrees and have a relatively thin snowpack. Other parts of Skyline Ridge have areas of thin snow. Avalanches can be triggered in these zones but they will propagate into deeper areas and make a large avalanche. Photo: GNFAC

    • Mount Abundance Avalanche

    On Saturday, March 15, a group of 14 snowmobilers from Cranbrook, Canada, were riding near Mount Abundance when two of the party triggered an avalanche high on the south face. This was the group’s first time to Cooke City and the last day of their five day trip. They were skilled riders, everyone had airbags, beacons, shovels and probes and two had taken an Avalanche Skills Training Course offered by the Canadian Avalanche Center.
