Scenario: Snowmobile Incident at Mt. Callaghan

A tragic incident occurred near Mt. Callaghan in British Columbia, where a 52-year-old man from Nanaimo died after a snow cornice collapsed beneath him.

According to RCMP, search and rescue teams were dispatched after reports that a snowmobiler had fallen from a cornice—a buildup of snow that can break unexpectedly.

The man had stopped his snowmobile on the edge when the cornice gave way. He fell approximately 250 feet and was partially buried in snow.

Nearby snowmobilers quickly responded:

• They dug him out of the snow
• Began CPR immediately

Despite their efforts, the man was pronounced dead at the scene.

The victim, identified as Karl Baker, was a long-time member of Nanaimo Search and Rescue and an advocate for avalanche safety and backcountry awareness.

This incident highlights how quickly conditions can change in winter environments—something that also applies across Manitoba’s rural areas and winter recreation zones.
