"It's hard to think about the magnitude of what's happened," Glacier National Park Conservancy executive director Doug Mitchell told the Kalispell Daily Inter Lake. "This was an iconic part of the park ... our role is to preserve and protect for future generations."
"This puts all hands on deck," he added. "We will marshal the troops and do what we can to help. Our mission is to be here for the long run."
Other beloved buildings remain endangered. Glacier shared photos on Monday of firetrucks outside its Lake McDonald Lodge, built in 1913. "Fire has not reached the lodge, but every precaution is being taken," it says in a Facebook post.
On Monday, wind gusts were blowing the fire toward the shores of the lake and endangering the lodge.
Mark Hufstetler, a historian who spent several years working at the lodge in the 1970s and 80s told The Associated Press it would be "unimaginably devastating" if the lodge were lost—especially given the destruction of Sperry Chalet.
"These are some of the most remarkable buildings anywhere in the United States and they are an integral part of the Glacier experience and the Glacier tradition," Hufstetler told the news service.
And then there are the trees.
