- A very memorable Saturday looking at Ice Age clues on the floor of Grand Coulee.
USGS geologist Brian Atwater is best known for his Cascadia Great Earthquake research.
Filmed on May 22, 2021.
WOW, I could watch Brian go on and on, he seems so excited he jumps around looking for the next clue postulating how the puzzle pieces could fit together. Thank you Nick, thank you Brian!
Thank you Nick.Thank you Brian.A beautiful day in the sage....with water and ROCKS.....
Dr. Atwater is a genius! Every geology student taking a class that involves field study should watch this. Thank you Brian and Nick!!
Agree 100%, watching Dr. Atwater in real time explain what's going on on that cliff is amazing. Show this to get students motivated prior to doing field work. You could send 1000 different geology majors to this site, and most would be clueless. I just see dirt, Dr. Atwater sees and explains thousands of years of geology.
Washington state is so beautiful.
Thanks for sharing these field trips w/us Nick.
Brian's input is fantastic.
Appreciate you both so much.
Wonderful experience for us! Thanks.
Thanks Nick & Brian - very instructive!
Thank you Nick and Brian
Wow! I am breathless trying to keep up with Brian Atwater. What an interesting day at the 'beach'. Thanks Nick and Brian, for sharing.
Brian and Nick are amazing individuals, they have way too much fun playing in the mud
Nick, I want back to watch the 1 hour mark and it’s really mind blowing to hear Brian discuss that Bretz had agreement about the prior cutting of Moses coulee. Thanks for pointing this out
Thanks for another opportunity to learn!
I thought I a good handle on this stuff and Brian just blew my mind. Big THANKS to Brian and Nick for showing me just how little I actually know. Very exciting!
Man he has the fever! I didn’t want it to end! Especially when you know he is going to keep talking! Great video!
Oh that was such a rare treat spending time with Brian and following along with his thinking as he digs around in the field. Awesome.
Very much to learn from this field trip. Thank you for this amazing video.
Instant classic. Thanks for documenting and sharing Brian Atwater in his element.
Brilliant! 3rd time watching this, will watch again, had to say Thank You. Nick and Brian, your time and knowledge are so valuable. To see environment that could be gone tomorrow, priceless.
All you geology fans...I am watching all the A to Z episodes again and I am getting so much more the second time around!
I did that about a month ago as well.
Same!
Can you point me to these?
it sounds so boring ....
can't stop watching
🤣🤣🤣
Overwhelmingly insightful and to "tag along" on a field trip with such knowledge, passion and drive; to learn.... Thank you Brian. Thank you Nick!!
It’s not hard to get those flood deposits up at pangborn, etc if the land is depressed as Atwater mentions, from glacial isostatic loading! They should re-run those simulations with a glacial isostasy loading parameter and use the mantle deformation rates to calculate timing, based on the necessary hydrological conditions to create the deposits. Or at least to establish bounds on timing, then maybe you can get some answers on when the ice retreated from grand coulee, for instance.
Wow, some really beautiful sedimentology there, hidden in the shadow of such an impressive rock. Love those varves overlying the beautiful ripples.
The varve/mud injectites speak to the instantaneous nature of the flood deposits IMO. so much sediment deposited so quickly on unlithified, wet sediment loads it, and causes the saturated sediment trapped below to flow as an overpressured liquid up into the bed above, and also is caused by dewatering structures.
Another explanation for that diamict (if it’s not a till) landslide/debris flows caused by destabilization of the land after flood scouring. But if there’s drop stones loading sediments underneath then it likely is glacial. And if it’s glacial, then that seems to imply ice advance, and lots of icebergs...
Also the coulee could have started to get cut during a previous glacial maximum, and there may have been cycles of glacial outburst floods during that time that then got scoured completely away and filled by the Missoula floods of the LGM ;)
Video stops right at the tillite money shot! Haha. Really appreciate this video, Nick. So much to read here, apologies for getting excited with this long comment.
I always wondered about this... I know they are having problems getting enough water to fill the high points. I also wonder if those high points are from the earliest floods when the floor of the Scablands wasn't as carved out like the later floods.
@@swirvinbirds1971 yeah could be
Just awesome. Thank you both so much. Love this keep it coming Nick.
This video really makes me wish I'd been a geologist. What a great, charming guide!
Thank you for posting this, Nick. Utterly delightful to watch him and listen to him. His enthusiasm is infectious.
Really interesting layers of TIME. …neat stuff .. thanks to you both !
Wow! Nick, you are in rarified company!
Fantastic! Reminds me of boating on Lake Roosevelt and observing those very same sediment exposure types. I wish you guys would get on a boat and cruise the Lake Roosevelt shoreline for a video, especially up the Spokane Arm. There are massive lakebed rip ups of the old Lake Columbia up there on the south shore near Porcupine Bay. As I recall, they were something like 6 feet or more high. Just imagine turning a swirled cinnamon roll on its side and looking straight at it. They were wonderful whorls of Missoula sand and Columbia clays. Also a giant sequence of rhythmites a good 20 feet high from a massive growing sandbar during one of the floods just east of Porcupine Bay where the lake gets really narrow.
Well, I caught parts of that, sure enjoyed it and didn't want it to end. Thank you
Isn't this a profoundly beautiful planet!😊
So nice to see Nick with his buddies and makes me feel like they are our friends too.
Thanks Brian for taking the time to make this video so enjoyable mostly because you are such a gentleman like all the USGS geologists are while teaching me something new and reminding me of previous publications I need to review again. Have a happy 60th birthday coming up );
The deposits of 1foot thick layer of unsorted rocks could come from local landslides?? Landslides possibly caused by a pool of water breaching on top of iceberg??--from Gene
Oh, WOW amazing experiences you guys brought to viewers, Brian and Nick! Thank You!! I love Brian's enthusiasm to go and still going head on to solve mysteries of Ice Age Floods, SO cool!!!
Love this series of field geologists at work. Looking at evidence and trying various stories to explain what is going on.
I have tried to tell some people about what Brian and Nick are telling us about the history of WA's geology and they seem to have no idea of the REAL history. I am 84 pushing 85 and love learning all of what they are telling me and all of you. I watch everything that Nick puts on my computer.
Re-visiting this after the Ice Age Floods A-Z series is a must. As Nick says in his lecture aeries, this was the lightbulb moment for Moses Coulee and revisiting Bretz work, and the Spokane ice sheet. Nothing beats field geology for getting at the truth.
Wow this was fun. Good camera work too, giving us very good looks at the cuts.
Brian Atwater - the Energizer Bunny has 'nothing' on this man. Simply amazing his knowledge and ENERGY.
WOW…. What a great tour with the famous Brian Atwater and hear his thinking!
They should link this video to the GSA field trip description. Fantastic video! 21k viewings (and counting) speaks to your skills Nick, and an under-appreciated demand for quality science videos. Thanks for sharing! (The best way to establish varves in my opinion is to show thickness correlations over many kms. Turbidites should be more localized and heavily influenced by the bathymetry. Those "varves" change significantly between 40 and 47:30 min - that was the same bed, right?)
GREAT STUFF!!! Cheers from Lewiston, Idaho"
This is so great. Thanks, you two.
A day in the field with Mr. Atwater?!?! Guaranteed I'll watch this one a few times! Thanx for taking us along, Nick! 👍🏽🤩
The drop stone at the 48 minute section: a Native American kid threw it in the lake? 🤷♂️😉
Yes, Legend. So much fun. Really enjoying this.
Where the "Older - Bigger, Younger - Smaller" theory was re-imagined. Thank you, Brian Atwater.
Love your work
That must be so exciting to walk around and to understand what going on with the earth around you
For the sake of history, it would be wonderful to record demonstrations of pre-gps, pre-computer geology. I really would love to see how you located yourself on the landscape w/o gps, how you mapped a quad on paper and many of the other techniques that are quickly disappearing from the field.
Basic map reading, feature location, and triangulation. Are you saying that geology students who don't already have the skills are not being taught them anymore? No different from hiking, really, and not getting lost. Basic skill for outdoorsmanship. I do admit topo maps on my handheld gps sure is nice, makes life easy.
Mr. Atwater is looking well
Great to see
Lol geologists are awesome! I get excited over things no one else does too!
Great one! Thanks Prof Nick!
The backflooding of quincy basin and the well weathered gravels, and the shoreline of glacial lake columbia, I couldn't find your videos on those but they sound like interesting topics. I wonder how much that "ambush meeting" on Bretz set our local geology back... We were just taught Missoula Missoula Missoula!
Hay Nick are we getting back to the rock and boulders. Thank you for sharing this video.this help with me to see the landscape in a deferent way .
Amazing! I just have to laugh when I see Brian so excited at the prospect that he has a new clue that he can identify. Also some grins when he starts to make a story about what he's found but then stops short and says someone else needs to examine it who knows more than he . He really is having too much fun pointing clues out to Nick.
Your friend Brian Atwater he's totally cool definitely into what he does best right on professors
Brilliant!
I'm such a geology geek that I would always end up playing in the mud on the lower Musselshell river when we were catfishing. Fossil hunting.
Nice video quality too along with great information
you guys rock!
Excellent lesson
Great stuff Nick! The last 10 minutes are gold, well worth the time for this education piece.Is the recent paper from Richards that Brian is talking about freely accessible?
Yes! Very good
My most enjoyed episode thus far (of many)
wow, simply amazing.
Damn. Looking good for 60s!
Very cool
welcome to third person saturday from an emotionally depressed landscape. sound.
Atwater for giving more clues
Whats the mineralogy of the sand? How does it affect the plants
He just barely touched on one of my favorite devices. The plate flex due to loading from ice and water. The intake level today may have been many feet higher. The coast would have flexed up from the trillions of megatons of sea water being removed from the subducting Pacific plate.
Wow oh wow!
26 min! And all the minutes Birddog [sedimentologist]-stratigrapher swami: the process of discovery. L- shaped injection current indicators! ❤️ it.
Now I gotta find Richard Foster Flint 1939 GSA ? article Brian mentioned Bulletin
I'm just watching this for the first time. At the time this was recorded, you and Brian were speculating on what forces could have caused the clay to intrude up into the voids in the sand (if that's the correct term).
Could it have been liquifaction? Could an earthquake have caused the clay to liquify, and the clay then flowed up into voids in the sand? Could this have happened in a later time period, not at all related to the Missoula floods?
i think my brain just broke....ouch!!!!
At 33:08 I and seeing vastly more layers than 5 to 10. I counted over 30 layers. The changes are subtle, and the colors can be
similar for several layers, then change from light to dark, OR, from dark to light. Maybe this results from different upstream sources of water and sediments.
At 40:30 is he saying the sims can't seem to get enough volume from Lake Missoula alone to explain the observations? e.g., high water marks - and that the silt dredged from lower glacial lakes may account for that extra volume?
Where is the “slack jaw” emoji?
Do the rythmites entomb evidence for bimodal water sources for the sed deposits? Or suggest single source?
Also are there any studies of microfossil variation between layers?
I love seeing geologists getting dirty… quite a workout for those old knees😀
Any chance those injections are from seismic shaking (liquefaction) rather than static loading?
I speculate that it was a mixture of the two but what do I know. In my mind it makes sense that such a large volume of water rushing through the area would create quit a bit of seismic activity.
Have I just been to a "Rock" Concert?
I think it was Muddy Waters
What a legend, Brian Atwater, retired and now working on glacial geomorphology in his spare time.
Just imagine being a young geologist assigned to help him on a project. Wow. This is a wonderful video that truly needs to be preserved.
Thank you for sharing this outing and BIG THANK YOU to Mr. Atwater for giving more clues to what HE see's when looking at a lake shore deposit. Most interesting! Thanks Nick
This is all amazing insight; geologist-to-geologist banter. This is gold, seeing how much they both enjoy their profession.
I sure hope we get to see more videos of Nick and Brian together like this! That was excellent!! Thank you so much for this!
“No, we both have old knees. We’ll need those knees to get back.” Ha!
It’s amazing watching and hearing Brians thought processes and methodology. I’m delighted to have had him share his vast experience, knowledge and enthusiasm with us. It gives me some insight as to how sediment is interpreted. I’m grateful for you sharing the experience.
Brian's like a kid in a candy shop. He clearly enjoys what he's doing.
both of them actually
Still a kid at 70! What a guy!
A fantastic video with so much information, I'll have to watch it 3 or 4 times. But it just kind of faded out. I assume your battery died. Hopefully you brought two and there will be a continuation of this great field trip. Thanks for doing this and sharing it with us. And a special thanks to Brian Atwater for his expertise. It looked like you were having the time of your life. :) Be well.
This is just an extraordinary piece Nick. Thanks to my having hung out with you so much the last year or so, I understand just enough of this to really appreciate how cool it is. The thing I like best about geology is trying to understand the landscape and picture the events over time that formed it. I'm not so good at remembering the names of things, but love the big story. When I look at something, I want to know why. I would never get to participate in an outing like this in real life without you bringing me along. My humble thanks to you and Brian for this treat. I hope you will discuss this further some time as I always have questions....which is why this is so cool because I'm looking at this stuff while having it interpreted by experts in real time. And... always remember, you might need those knees to get back. Good advice.
I'm kinda like you in that regard -- I'm into the MACRO-geology, not the micro-stuff. What Dr. Atwater and Nick dive into is very nuanced minutiae that add up to this big picture that I'm _most_ interested in. Within the micro is the evidence, within the evidence is the whole of the story. _That's_ what I'm into, not the parts that make up the whole, but the whole itself.
Yet another great glimpse of a Field geologist at work. Very interesting to see both the evidence and interpretations.
It doesn't get any better than this!!! A new Scablands story in the making. Absolutely stunning!! Thank you so much!!
An hour of bliss!
Blows my mind on how complicated ice age deposits are!
The biggest take away from the class today is the power of observation, GREAT WORK
What an irrepressible soul! You can’t fake that kind of passion. What a treasure of a human! Thanks Nick for sharing him with us.
Thanks for the fun walk with geologic interpretations. A lot more interesting than going by yourself and looking at something and not understanding it
Thank you Nick,always waiting for a new field video.
Brian is a detail man. A technician. He let's other deeper thinkers explain his findings. He seems confused, but not. Other enlightened beings will come along and if he details enough they will enlighten us to the area history. His information is too dense to interpret. Like Nick he is asking the question, no answers just questions that show the Missoula floods were not in any way as simple as Nick was explaining 4 years past.
OMG. I am reading FULL RIP 9.0 (Sandi Doughton) and the 2nd chapter starts with the name: BRIAN ATWATER. Believe me, folks. After you read the 1st chapter, this man's name, BRIAN ATWATER, comes into full focus. You GET it, why Nick Zentner mentions this scientist in his videos. Jiminy! Total Respect and Gratitude to you both. And let's hope Cascadia slumbers into millenia.
