Your explanation of the swirling water creating the potholes was a necessary bit of information that I enjoyed...thanks! Nice job...I will see them in 3 days.
@@melodiefrances3898 Yup.... bet there were people that witnessed it or had their village wash away. Everything that could happen in geology happened in Washington. It's a very interesting area. I watch Nick Zenter classes on that region.
Great video! Amazing photography, beautiful scenery. I rode through the area as a Boy Scout, on the way to the 1973 Jamboree in Idaho. I can honestly say if we had stopped, or seen any of this, I might have become a Geologist, instead of a Paramedic.
Thank you, thank you, thank you! I live in Vermont and have never seen anything remotely like the scablands. I have see other youtubes about the scablands and coulees but none that depict and honor them as well. The pace and close up views of the various features are helpful and mesmerizing. Music and narration befitted beautifully to the respect and wonder the ancient landscape deserves. I wish there were more such productions for other natural phenomenon in the US and around the world...
Some kind of flow separation occurs when floodwater spreads out. Mostly it’s two cataracts, but at Dry Falls, which is wider, there are three cataracts.
Amazing as always. I watch these videos often and I still can't manage to wrap my mind around the power of these floods and what they must have looked and sounded like.
I was thrilled you mentioned all the paired dry falls. Do you have a theory as to WHY these cataracts seem to be binary? Philippi Canyon, which I just watched, also has this feature.
Another great video! Thanks so much! There's one thing I wonder, though. With the powerful flood stream dropping perpendicularly into the Columbia river valley - shouldn't there be signs of an impact opposite of Potholes and Frenchman coulee?
@@bjornstad51 Is that the defined terrace lines we can see via google street view on the west bank? Might there be a good photo at a descriptive angle to further describe this feature for those interested? Thank you for the video! Possibility for a mic setting with less white noise or that might pick up less background hiss when recording the voice audio? Might it be the audio level when recording, in my experience higher input levels tend to have that artifact, anything over ~70% input level tends to add this audio hissing phenomena, and lower recorded audio level "without hiss" can be then increased in most editing software to the users desired output level.
Common theory is, Missoula floods were gradual and occurred many times over a long period. At about 5:00, you (Bjornstad) indicate the Quincy Basin would have had to fill quickly, Drumheller Channels are lower in elevation that Frenchmen, Craters, and Potholes Coulees, and if it was a series of smaller or continuous flooding, the flood-waters would have simply drained to the SE through the Drumheller Channels. These examples lead me to believe you perhaps are open to the Younger Dryas Theory, or one of your own (Bjornstad)?
Potholes Coulee formed from repeated megafloods from glacial Lake Missoula., the last of which was ~15k years ago. There is NO evidence of megafloods in the Pacific NW during the YD, which occurred 3000 years later!
@@IceAgeFloodscapes I thought the quality was excellent but it would be amazing if it was possible to improve on it. I know I viewed the production using full screen mode.
@@IceAgeFloodscapes then you haven’t actually looked at the evidence thoroughly… I can’t convince you you just need to look for yourself and decide. I hope you don’t think that Clovis people killed ALL the megafauna. Don’t limit yourself to handpicked and cherry picked evidence. It’s a culmination of all sciences in many different branches to see the facts. Great footage though. Facts are the realization that we still don’t have the actual final answer. There is still a story yet to be told
@@Bowsniper73 YOU are the one who hasn't looked at the evidence. These geologic features (such as potholes coulee) were caused by a sequence of floods spanning thousands of years, not by a few catastrophic events as Carlson proposes. Also, have some respect. Bruce has spent a lifetime studying this area, doing fieldwork, and taking drone footage to share his knowledge with a wider audience. For you to come here and talk down to him as if he doesn't know the subject matter is laughable.
