Per NWAC and elsewhere, it sounds like there has been another accident:
In today's forecast statement: "Late Saturday we received reports of an avalanche fatality on Park Butte near Mt Baker. One snowmobiler was caught, carried, and killed in the accident. Initial reports indicate the avalanche occurred on a NE aspect near 5300'."
