Thorp Lahars - GEOL 101 LAB 

Ned Zinger's "Crocs-on-the-Rocks" series. A Zinger-Zetner enterprise.

So, we're driving over this mountain road having no clue, until now, that the amazing geologic structures flashing by the windows are 10 million years old! It's incredible! I know I keep saying this, but I love these videos! And we all love Nick!

A couple years ago I stopped at this spot. I would have loved to have had Ned with me that day. Thanks!

Love that Nick does his own stunts with the truck at the end!! Watching you for years!

Man I love this being shown things I could have never known otherwise this is so fun!

I drove to Sonora today looking at metamorphic sea floor shifted 90* with pillow lava on top and basaltic grantet not far away thx nick for giving a noob a new way of looking at the land!

A thumbs up for all the comments below, and a massive THUMBS UP to you Nick for another Gem. Can't wait for the next one. Pete on the Isle of Wight. LOL

Watching with headphones in, dozed off for a bit (sorry, super tired) until you yelled! Ha! Rude awakening, that'll teach me!!!! Glad you survived, LOL!

You put the Zing into learning and with the way things are going, just in the Nick of time!

From a non-geologist but one who has been interested for ages this is great. Thanks! While on trips around the US and abroad I have always thought "Where's that geologist when I need one?" I lived for a while in Kenya in the Nyambene Range in a village at about 6000 ft, and nearby was a rock quarry where stone was quarried to build the school, the clinic and some homes. I was in heaven at the quarry and wished someone was at hand to explain what was going on! Looking forward to more field trips. Oh and back in 1981 I got to participate in a paleontological field trip to the Fort Peck Dam area in MT for 2+ weeks with a prof from the U Of Minn and a group of his students. Being an extra pair of hands I was richly rewarded and learned a great deal on that trip!

I've watched many a lahar video on RU-vid and I find them fascinating and scary. Mostly the vids are shot by locals with their phones, following the first trickles of muddly material as they grow to grey slurries and then thundering flows containing boulders the size of buildings. Nick's pink boulder is exactly like these massive chunks of material.

Thanks Nick. I love learning about where I live

Thanks Nick for disseminating your expertise, and making us more knowledgeable. Keep on truckin'!

Thanks Nick! I never thought that Geology is so fascinating. You made it enjoyable. Watching, sharing your videos as possible. Thank you very much!!!

What, Jim and Lana have the "Where's Nick Right Now" App?

Learnt loads. Love the format. Cheers from Jane in Hereford in England. Thank you, Nick.

thank you for your excellent teaching from Mainz Germany

HIT THUMBS UP FOR NICK!

People rarely stop here unless they are lost and see an internet famous professor of geology talking into his phone! LOL

Love you my Brother Thanks for giving all you do.

Years ago, my husband and I lived right across the river from this. We always wanted to know. Thanks

I'm an amateur geologist and rock hound. I love your videos. Very informative. I feel like I'm one of your students. Thank you so much!

I would have loved having you as a prof.

Nick survived the lahar because of his stylish black Crocs.

Your knee replacement scars have healed well Nick. My dad just had the last of his knee replacement ops recently

Thanks Nick! Great zooms - we can see the grains clearly! 👍👍

I suppose the silver lining of getting smashed by a lahar is that you would make a cool fossil.

Love the way you teach.

That was great! I can confirm for folks wary of hwy 10, there are some of these formations along the Palouse-Cascades trail, on the right, more than a mile east of the tunnel. Not nearly as big or dramatic, but I was thrilled to round a corner on Saturday and recognize them.

I applaud your method for viewing outcrops and specimens. You’re simply showing people how to see. Observe what you see. Describe what you see in simple compositional terms. Make some inferences and analyses about how the data came to be. Develop a story or hypothesis and go back and test it with the data. As a fellow educator, I gotta say you teach in a way that I’d like to emulate.

I guessed right, I drove though St Helens the day after coming from California to visit family in Washington, I only knew earthquakes and my days renting a plane and flying solo over the San Andreas, and Owens Valley, much more active here in WA.

When the sun hits the massive just right I can almost see faint layers

Thanks Ned

Nick, I would hope that you would consider talking about plate rollback theory at some point. Thanks for everything!!!

Mind -blown 🤯

Enjoyed as always!

Smooth sculpted surfaces; yes, many layers.

9:13 spoiler alert 12:09 coffee break 29:50 Uniformitarian principle aplication It must coincide direction marks from the ripples and cross lamination from sandtone, with the volcanic mud-flow layer erosional marks. Could be interesting take a look about that to your pupils. Great job. Love your work.

I would have thought that the rocky layer was a lake bed.

I have been seeing what I think are lahars on the Columbia, Rt. 84 roadcuts near Maltnoma falls, poorly sorted big boulders suspended in whitish sandstone looking wall.

You've got the best massive unit Nick

If the layed material is river rock, why is it so poorly sorted?

I'm not quite sure why this 10 myo series of lahars didn't erode away when the volcano they came from did.

Drove by that many time I always said hey there is that sandstone! Didnt I see a thin layer of pink rock somewhere Along hiway 10?

CWU has a geology KML file for Google Earth.

Any relation to Thorp, Wisconsin? It's where.most of my family is from. Beautiful dairy area.

Now would there be any gold in that river rock layer?

I would have expected a color differentiation between the river deposits and the lahar deposits....

Lahars are alright with me.

Is there a 'Go Fund Me' to get muffler boy a new muffler. i want to contribute.

How do you know it was a Tuesday?

At first near the bottom I was thinking "glacial deposit", but going up, I'm thinking flooding with sediment on top??

Thanks for your video. A drone will help you a lot I guess 👍👍

Hey Nick, i will give you $40 for the admission for MT Rainer National park so you can do some videos there Just came back from paradise and sunrise park, and i have many questions about the Geology and im sure others like myself would like to see it. the pass lasts for 7 days sooo... 🤔🤷 free pass right here just saying, love the videos Nick!

River Cobbles 3:30

Let me guess, tree.

I guess I missed the story about why he’s calling himself Ned Zinger. Did someone call him that one time and he decided to go with it? Lol. Also, he previously mentioned he’s 280 lbs but must be about 6’5” or something because 280 doesn’t look bad on him.

Looks like blown concrete

AT 16:50 LOGEPOLE PINE,(hehehe)😉

Tree!! at 16:37

I'm going to stick with my hypothesis that this was a result of a pyroclastic flow due to how easily the sediment crumbles and looks like corse ash and ground up pumice. If it was a Lahar which flows like muddy cement I think after a couple of million years it would have hardened enough so you would need a hammer to break it apart.

The Clackamas River in Oregon has a 50 foot deep lahar @70 river miles downriver from its source on Olallie Butte, a shield volcano @15 miles North of 10,500’ Mt. Jefferson.

My first observation was the windmill in the upper left corner of the screen.

You are a National Treasure! Thank you for your incredible videos!

Another winner! But you should really consider wearing an orange safety vest on busy highways. Safety first!

I was totally waiting for Muffler Boy to drive by lol.

Hey Ned Zinger! Geologists aren’t supposed to funny ! Never met one yet with a sense of humor. Till now!

Franz Lehár; (30 April 1870 - 24 October 1948) was an Austro-Hungarian composer. I'm resisting scratching "Franz was here" on that massive grey wall...

I've seen formations like this in extreme southern Idaho above Utah. Really nice to finally know what they are, Nick. Thank you for another informative video. Jim

I just finished your podcast, it's great. As much as you love RU-vid, I do appreciate the in-depth look at the geology and your thoughts.

Ned Zinger -- you're awesome. So are those rocks.

I have spent quite a bit of time looking at this area. I had no idea this originated from a volcano now long gone. Interesting video.

Thanks Nick, you got me thinking about that outcrops features were puzzling...they seem to me to be perhaps the over wash from the pacific ocean leaving its basin and sloshing over the land and then retreating back as it stabilizes into its new low points.....leaving those features layered one direction with its specific till and the other; the retreat along with its own particular till....just thinkin :)

Get some Chaco’s for your feet, the kind with the big-toe loop. You’ll thank me later. I’m learning so much about my home from you. Thank you.

I wish you would come down to the Grand Junction, Colorado area! I'm no geologist, but love learning what's around me. We live almost next to National Monument. If you're ever in the neighborhood, I'd show you around.

Found this article today, Nick. Thought you might find it interesting (not related to the topic above, just geology in general) www.geologyin.com/2016/06/opal-discovered-in-antarctic-meteorite.html?fbclid=IwAR2_WWqoOWz_YnnW9w2JnZocfes0aIHGN7aBvU-YmgbrqjP6el-typq4MWM

That block has at least 10 deposition layers. The curve under the pink ball looks the same as a puddle in a river. I do not doubt the lahare.

I got somewhat distracted by his massive unit.

Thanks for posting these. We made the long drive between Oregon and Montana for years. We took various routes and tried our best to guess at various geographic sites. This answers some of those questions. We are in Michigan living on the Southeast end of Lake Michigan. I spend a lot of time trying to figure out what kind of beach rock I'm holding and how it possibly got to our sandy beach. I found a rock with iron on one side and need to figure out where iron is found.

Excellrnt yet again. You should be a teacher 🙂

Wow.! Looks beautiful there. Yakima river looks beautiful too. Beautiful rocks too.! I love learning bout volcanoes, volcanic rocks and etc. There shouldn't be thumbs down.!

Yes Loved it and the truck.

Cheers to old guy sounds!

i'm glad you survived !

Very cool

WHOA ! NIIIIIIICE. NICE !!

I find it interesting to realize that the evidence far outlives the volcano.

*Nick,* I re-watched this 3 hours after the premiere - no buffering issues whatsoever. I speculate that there was a network bandwidth limit at or near the source that couldn't handle 300 simultaneous users during the first viewing. BTW, we are knee scar brothers.

Really enjoyed this one I was so chuffed when I remember things. Knew it was mud but forgot the term for the flow (and the spelling) . Thank you

Would never survive... my brain filled in the blank with "pressures"

Always nice to see "fresh" volcanic material and evidence, s the stuff in my area (Borrowdale Group) is 100's of millions of years old.

Thank you again for another great lesson in geology. Hope to visit this location on my trip to Alaska, and across the US next summer!

There is a lot of fine stratification within the massive. There are verticle groups containing larger stones. They are less horizontal. The depositional layers are in appearence similar. The strat appears to have more similar material for the thick massive and return to more variable materials.

So this is a very tiny slice of a very large debris field/flow but wouldn't one expect some tree trunks or other plants petrified within?

I loved it, thank you very much for sharing years of experience with me. You make learning fun Ned Zinger😉😎

I love roadside geology, much of my degree field work was roadsides, roads cut through rocks like nothin else !

🌋Ahhh!!…. I’m a piece of clast 🗿

Do we really need a volcano? Couldn't a CME super flare or air exploding asteroid do the same? Asking for a friend.

Sir you should have all of the rocks you collect tested for DNA.

we have layered rocky stuff up here in bc too:)
