The Lobby Fireplace - Yellowstone Lodge
The 1959 Hebgen Lake earthquake moved this fireplace 3 feet to the right of it's foundation. It has been rebuilt and the foundation replaced in it's original location with more stablized earthquake proof rebar to prevent movement in the event of another earthquake of this magnitude. Yellowstone has some 1,000 to 3,000 earthquakes per year . Only a few of them are strong enough to be felt.
