The Channeled Scablands of eastern Washington preserve Dry Falls, a former cataract about 3 miles (roughly 5 km) wide and 400 feet high. The video cites discharge estimates above 300 million cubic feet per second for the Missoula floods and argues that peak water stood 400 feet above the rim, leaving no visible waterfall; below the cataract, it says flow reached 800 feet deep. It describes Niagara's horseshoe as a “recessional cataract” shaped by repeated erosion and links that form to the Scablands cataracts. It dates the canyon cutting to brief glacial–interglacial transitions, with a window of no more than about 3,000 years and the actual cutting taking weeks or less. 💧⛰️
Video cites 300M+ cfs Scablands floods and a 3-mile cataract
Key facts
- Dry Falls, the Scablands cataract described, was about 3 miles (roughly 5 km) wide and 400 feet high—not 5 miles wide.
- The video cites discharge estimates above 300 million cubic feet per second for the Missoula floods.
- The video argues that peak water stood about 400 feet above the cataract rim and reached about 800 feet deep below it.
- The video describes Niagara's horseshoe as a recessional cataract shaped by repeated erosion and links that form to the Scablands cataracts.
- The video dates the canyon cutting to brief glacial–interglacial transitions, with a total window of no more than about 3,000 years and the cutting itself taking weeks or less.
