Could it be described as flooding of Biblical proportions? I don't know if you can go that far, but check out this video from flooding in Yellowstone National Park, to Natural Bridge, flooding down the streets of Red Lodge, House Rock being nearly overtaken on the Gallatin River, and a riverfront home on the brink of being washed down the river in Gardiner, Montana.
Gallatin County dispatch received a report that a vehicle had left the roadway and gone into the Gallatin River on U.S. Highway 191, at mile-marker 70.
It's true. It's actually gone. As in, not part of the flowing East Gallatin River anymore due to recent flooding activity. A perfect example of Mother Nature doing whatever she wants.
