Warm Springs Lodge at the Sun Valley Resort in Ketchum suffered more than $1 million dollars in damage from a fire late Wednesday.
Because of the extent of the damage, the Bureau of Alcohol, Tobacco and Firearms will join the Ketchum Fire Department and Idaho State Fire Marshal in investigating the cause of the fire.
Firefighters were still working to completely suppress the fire by 3 p.m. on Thursday, Sun Valley Resort officials said.
The lodge's alarm system was triggered about 11:20 p.m. Wednesday, according to Sun Valley Resort, and crews from several agencies fought the blaze at the base of Bald Mountain until late Thursday morning, according to the Idaho Mountain Express.
According to a resort press release, Ketchum police arrived to 30-foot flames shooting from the building. Flames burned through the middle of the lodge's roof, the Mountain Express reported, but the outer walls were intact Thursday.
Sun Valley Resort officials said Thursday afternoon that no injuries had been reported. The cause of the fire hasn't been determined.
Lusk said the ski area closed Sunday and the day lodge, which houses food services, lockers and retail space, had closed for the season and wasn’t open to the public.
