Kilmorey Lodge Waterton

How did the Kilmorey Lodge in Waterton, Canada burn down?
Spontaneous combustion in the laundry room.
A load of laundry was completed and folded while still warm and placed in a cloth tote bag. The combined heat generated in the bag was sufficient to start this laundry and tote bag on fire, which in turn started the entire wooden structure of the lodge on fire.
