Yellowstone River Flood: Floating House Hits A Bridge Massive flood hits Corwin Springs and takes houses down the Yellowstone River in Montana. The magnitude of the flood was so massive that it took the house down 7 miles before hitting the side of the bridge nearby. One of the bystanders presents near the bank recorded the entire event. Footage also shows that people rushed in groups to witness the house being dragged down and then collapsing against the bridge. #flood #flashflood #flood #dange
