GLACIER NATIONAL PARK - Glacier National Park officials said that at about 6 p.m. Thursday the main building at the Sperry Chalet was lost to the Sprague Fire.
GNP officials said on their Facebook page that a group of firefighters were staged at the Sperry Chalet over the last week.
"Those firefighters had an extensive hose lay, sprinkler and pump system installed to protect all of the structures associated with the Chalet," park officials said.
GNP officials said high winds pushed the fire to the east on Thursday.
"The firefighters, supported by 3 helicopters, made a valiant stand to save the structure but were unsuccessful in saving the main Sperry Chalet," GNP officials said. "The firefighters remain on site, ARE SAFE, and are currently actively engaged in protecting the remaining structures."
The Sprague Fire burning on the east side of Lake McDonald has now grown to nearly 2,100 acres.
