RCMP received several distress beacon calls around 12:30 p.m. PT Saturday, pinpointing the location of a slide at Goat Ridge in the Clemina Creek snowmobile area, about 30 kilometres south of Valemount off Highway 5.
RCMP said several snowmobile riders were in the area and that one man was found dead.
Search and Rescue teams from Valemount and McBride, about an hour north of Valemount, were dispatched to the scene. However, avalanche technicians determined that the area was too dangerous for emergency crews to enter.
A statement from the RCMP issued Saturday night said that once conditions improve, the B.C. Coroners Service will enter to the area to recover the body.
The RCMP also sent a warning Sunday that no outdoor activity should take place in the area due to the high risk of slides.
Last week, an avalanche buried a section of Highway 16 near Valemount. No one was injured and the highway did reopen.
Valemount is about five hours west of Edmonton and 3½ hours northeast of Kamloops, B.C.
