Crews have finished stabilizing the Sperry Chalet for the winter after the dormitory building was burned on August 31 due to the Sprague Fire.
A 10-person crew flew to the chalet on October 4 and braced walls, gables, windows, and chimneys to prevent them from toppling when heavy snow and winds arrive.
Fifteen helicopter trips transported the materials to the area.
Cold weather, freezing rain, and snow affected stabilization efforts but the crew left the mountain on October 16.
The Park will decide how to fix the chalet in the spring after surveying how the structure weathered the winter.
The Glacier National Park Conservancy launched the Sperry Action Fund campaign, which supported nearly all of the stabilization efforts.
The trail to the Sperry Chalet remains impassable as are other trails in the Sprague Fire area.
Nearly 2,000 trees fell across trails as a result of the fire and the Park estimates that another 1,000 may fall across trails this winter.
