GNFAC Reports Avalanche Fatality On Henderson Mountain Near Cooke City, Montana
Cooke City, Montana – On Sunday, December 11, 2016 a skier was killed in an avalanche on Henderson Mountain (10338’) in the Beartooth Mountains outside of Cooke City, Montana. Another skier was partially buried, but escaped without injury.
The avalanche is initially being reported as “upwards of 6 feet deep and 100 feet wide and ran through timber.” The GNFAC reported the avalanche danger as “considerable” in Cooke City on 12/11/16.
At this point, details are extremely limited. This incident was reported by the Friends Of The Gallatin National Forest Avalanche Center’s Facebook page:
- The avalanche victim has been identified as Christopher Peterson, 55, from Ketchum Idaho (KBZK.com).
- The group skied the slope “at least a couple of times” before it slid. It took 15-20 minutes to locate the victim, who was buried under about 5 feet of snow near a tree (ExploreBigSky.com).
- Doug Chabot and Eric Knoff of the GNFAC visited the scene of the Henderson Bench accident fatality on 12/12. The “slide was 250′ vertical, 3′ deep and 80-150′ wide.” The snow failed on facets on top of a firm ice crust. The starting zone at the crown was roughly 35 degrees and rolls over onto a heavily treed 40 degree slope. Watch the following video to see the accident site and the crown:
- In the GNFAC Avalanche Advisory for 12/13, they wrote that “skier was in a party of 5 and his descent was the 7th track on the slope when it avalanched.“
