USA/WA: Dry Falls
Dry Falls is where a prehistoric massive waterfall used to flow during or right after the last ice age, about 20,000 years ago when the receding glaciers damned two massive rivers and formed a lake that eventually broke through. These falls were supposedly five times the width of Niagara and ten times the flow of all the rivers in the world combined. It’s a massive precipice where you stand on the edge overlooking the deep and dry plunge pools below you. The resulting flood was so massive that it put three present day states under hundreds of feet of water.
