HELENA, Mont. (AP) — The National Park Service released four concepts for the restoration of Glacier National Park's Sperry Chalet dormitory.

The Independent Record reports the concepts, released Wednesday, range from stabilizing the walls but not rebuilding the structure — instead, setting up temporary wall tents for visitors — to reconstructing the dorm to as "close to as it was" with some critical building code updates.

Other options under consideration are to restore the dormitory "in place, but modernized," or moving the building's location so it's beyond recent avalanche activity. The latter option would involve stabilizing the remaining walls and providing visitor interpretation of the original structure.

The options can be viewed online at parkplanning.nps.gov. The comment period for the project closes Monday, April 2.
