You don't have to stick to the rivers and lakes that you're used to. Frozen waterfalls are something I never thought about. I just figured as long as water was moving it wasn't really going to freeze. Apparently, I am wrong. You can check out several different frozen waterfalls around the area and they are stunning.
I want to be clear that no bears were harmed in the making of this video. It was an innocent moment when a bear misjudged a stream and ended up going over one of the waterfalls in Yellowstone National Park.
