At just after 4 p.m. on Sunday, December 2, a 17-year-old girl from Alanson was involved in an accident while snowboarding at Boyne Highlands Resort.Source
The accident occurred on Camelot, a beginner rated slope. A witness with the snowboarder said that she fell within the slope boundaries and did not collide with any type of obstacle. Snow and weather conditions at the time of the accident were described as wet snow, with temperatures in the mid-40s.
The snowboarder was treated at the scene by Boyne Highlands’ Ski Patrol. She was then transferred by ambulance to McLaren – Northern Michigan Hospital in Petoskey, where she later died.
“We are deeply saddened by this accident,” said Brad Keen, president and general manager of Boyne Highlands Resort. “Our heartfelt condolences go out to her family and friends.”
It is not known if the snowboarder was wearing a helmet at the time of the incident.
Due to concerns about patient and family confidentiality, Boyne Highlands does not identify persons who are injured nor share information about injuries sustained at the ski area.
I was there the day prior. Great conditions. It rained overnight though and it was in the mid-40's so I declined riding the slush on Sunday.
I'm not sure what the heck happened. This is a super mellow run, not very long and no trees. She could have hit a fence or maybe she just caught a nasty edge and slammed her head.
