NEW Nick on the Rocks??? Yes!! I've never clicked on a notification so fast before! Nick is an international treasure and has been instrumental in getting so many people passionate about geology and geomorphology and understanding more about the natural history around them. Thanks for all that you do. I would love to come to one of his lectures. I'm actually going to be moving to the Portland area at some point and would love to find out how to attend one of his live lectures. If anyone knows how, please let me know.
Call the Central Washington University and find out when his classes take place. They are open to the public to attend for free on an audit basis. He won’t mind you being there.
He loves having people in class, when I did geo 101 we had a few stragglers every other lecture. Always fun! Usually he has class lectures twice weekly, but Nick also does pop-up lectures at random that you could visit if you're willing to only have a few days notice.
I once read the section on Missoula Floods in my Roadside Geology of WA book out loud while my husband and I drove across the state. It's such a fascinating event to imagine water roaring through those coulees! And my husband tolerated me essentially acting as a distracted audio book. Love these videos, short and sweet, but super informative.
That simulated flood looks like a gigantic version of the 2011 Tohoku tsunami which had waves over 100 feet high in some places. Water moving at high speed is a frightening force of nature.
Is it possible that the Wailua gap was far narrower during the Ice Age floods since it is only approximately 1 mile wide today it must’ve been much narrower and has eroded to its current width because of the Ice Age floods, what do you all think of that idea?
I'll bring this up with Nick when classes start next month, it's a super interesting theory that I think has weight! However, we learned that everything basically stopped in a massive river right before the gap, so I don't think erosion would have been as intense as you're expecting.
@@Chirkrasia Well, if it is from the same CBG rocks wouldn’t it be jus as cracked, fractured as all basalt in that area, and as water is restricted in the Venturi of the gap velocity of the water would increase which in theory would give even more erosion effect to the basalt? Nick is a fabulous teacher, I love the way he presents data to us. I have been watching the videos of the Iceland volcanoes eruption and it seems that lava does not run as far as the CBG did, could the lava of 20 million years ago been far hotter ? Thanks for the chance to ask questions.
@@Chirkrasia I'd be curious to know this as well. A volume of water accelerates when it's channeled through a narrow section, which when combined with sediment and debris in the flow could increase erosion, especially at peak flow rate. Though, as the gap erodes and gets wider, the flow would become slower. I'm not a geologist or hydrologist, I'm just a kayaker 🙂
Awesome, so glad to see this again, Nick!!! At the wineries in the Willamette Valley, we reference the Missoula floods all the time, it would be awesome for you to connect with the OSU team and create an animation like the first Dry Falls? I hear a lot of inaccurate info.
The North American Ice age floods are unique, for the European Ice öakes had their outlet northward to the Baltic sea amd the North Sea. But 9000 years ago there were the the Storegga landsöide causing a gigamtic tsunami devastating Britain, Northern Germany amd devouring the big osland of Doggerland
