As many as six sledders missing after venturing into remote north Okanagan area

VERNON, B.C. — A group of snowmobilers is missing in British Columbia's north Okanagan, a region where searchers say avalanche risks are extreme.

The snowmobilers are from the Vernon area and were reported missing Sunday night.

Vernon Search and Rescue spokesman Pete Wise says the group set out Sunday in the Pinnacles area outside Cherryville, about 50 kilometres east of Vernon.

Wise says the five or six sledders haven't been heard from since.

A helicopter, RCMP avalanche technician and search dog were sent to the remote area early Monday. 

Two separate weekend avalanches near Golden killed one Alberta man and injured three other people, one of them critically. (CKIZ)
