Hey,it’s #FunFactFriday ! If you’ve ever visited any of the view areas along the lower falls of the Yellowstone River in Yellowstone National Park, then you’ve probably noticed a green streek of water at the top of the waterfall.
As you know, the water from the riverbed, when it falls over the edge of the cliff, becomes a mixture of spray and turbulence, much like when water flows over a shallow, rocky portion of a riverbed, streambed, or creekbed. So, there’s a notch in the Yellowstone riverbed, right at the lip of the falls, extending down a little bit past the edge. This notch allows for a short, deeper flow of the riverwater to maintain its beautiful, clear green color before ultimately changing to spray / turbulance as it falls over and then outward from the cliff edge.
And now you know!
