Which lodge was destroyed by the wildfires?

Sperry chalet was destroyed by the Sprague fire August 31, 2017. Sperry provided some overnight lodging during summer months but is not one of the "lodges" in GNP.

Lake MacDonald lodge ested in 1913

None of the lodges were burnt, but the Sperry Chalet was.

The visitor's center in Waterton Lakes NP in Alberta bunt down last week which is just north of GNP.

If you mean the 2017 fires, no lodges have been destroyed at this point.

I believe some were threatened and evacuated as a precaution, but none actually destroyed .
