If anyone did mineral exploration in the South Nahanni River valley, in the years between 1978 and 1983, I would love to say hello. Nice presentation KZfaq needs more about BC and Yukon Geology geology.

Do you need to have oxygen to generate so much heat for molten lava?

Wow. Terrific talk! Think I'll watch it again.

This video was just added to my feed. Really sorry I missed this it last month. Great information as usual.

All fossils are fake

An excellent and accurate overview of the history of gold mining in Oregon. Thank you!

Thank-you for a splendid presentation of some interesting papers. Apparently though. junk climate hysteria "science" finds a way to creep in. Always an undiscovered, menacing new positive CO2 feedback/"further research" funding loop to be found. Never heard of a "cascading" one till now. Great microscopy on the Lunar meteorite. Has any evidence of hydrothermal alteration in the total Lunar sample suite ever been observed? All the best from Namibia.

Nice talk, good detail on SEM methodology. Interesting subduction paper, and others. I enjoy reviews like these, And you read well. Thanks to both presenters!

You want to start about 10min in.

There is no accent in the pronunciation of Lyell.

Hello Daniel. I want to send you some pics of a very nice meteorite. Could you give me a whatsapp number ? Thanks.

Where does he say has the free lidar files to download?

There are a great many "loess" hills. Yucaipa, in southern California, sits atop a ridge of mud, pushed up by the returning tsunami that struck Asia, in Emperor Yu's time, most probably. The valleys behind it (easterly) are clogged mud hills. Cajon Pass was carved by the massive wall of water that swept across the West, hit the monolith of the Sierras/Cascades, and turned southerly, washing up against the Transverse Mountains, with plenty of water washing over the edge, to carve out the area from the freeway to Deep Creek. Silverwood Lake was probably filled at the time, a natural depression that held whatever water splashed against the San Bernardino Mountains. A massive gravel plume exits the San Gabriel Mountains, spreading across the valley floor all the way out to El Mirage Dry Lake, with an arc of spume at its end. The head of the plume points at Wrightwood, a cove in the uplifted San Gabriels.

I'm glad the algorithm showed me Nick again!

Tks for sharing found a brass pin had come out not allowing the choke arm to actuate the blades in the carb. I'm 50+ yrs old and only now getting mechanically interested to fix my small engine tools. Now gotta go find that part number off the pdf.

Nick you are a rockstar!

How about the great Randall Carlson?

You should Google ICR for the correct interpretation of the flood evidence in the Northwest. The narrator is not accounting for the plate pressure regarding the elevation during the flood.

I would like to see what the radio isotope ages of the new Hawaiian lava that has just risen to the surface and solidified.

True national treasure. Rare combination of knowledge and presentation skills combined with genuine joy he gets from teaching and learning

audio when you’re near the lectern is good but when you walk away from it the echo on surround sound renders it unwatchable…luckily I have an ipad to switch to which makes this far less noticeable

Geology is about massive global phenomena of continental drift, uplifting bedrock, supervolcanoes, violent or eternal chemistry and deeply layered tuff, soils and silts... And then come Nick and his merry band of Zentnerds.

Really enjoying this presentation. Pausing partway through to comment. Analogies work really well for me. I’m not a geologist, but am an enthusiast who lives in a very geologically rich area of North America. A few thousand kilometres north of this presentation topic area. Maybe kilometres gives away my location, eh? But I find a lot of what happened and was studied down in your neck of the woods explains what has happened up here. Appreciate your style of presentation.

I love this Ned Zinger Guy!!!

I've missed you. The last A-Z I saw was Exotic Terranes. Then real life intruded (as it always does). This was a marvelous presentation and a call to me to get back to Washington geology. Having lived in Dayton for three years I still am impressed with the Palouse's beauty (but not so much impressed by the dust LOL). Be well, Nick. May you be abundantly blessed forever. :)

An excellent talk and a nice summary of the A -> Z series Nick did. Thank to Nick and ALL his teaching, videos, research, collaborations and more. He's a great teacher.

I grew up trapped between 2 groups of people. If I had a question about rocks, floods, dinosaurs, wooly mammoths, stars, planets, monkeys, or whatever? One group had their dusty old textbooks to refer to, the other group quoted book, chapter, and verse from their bible and said THAT was the answer. Mr Bakers description of physicist vs geologist thinking sounds like the problem I had with both groups! Then life went on for 50 years. With the advent of leisure time and internet videos / podcasts, I have finally discovered a group of people who make sense to me. The amazing thing is how many of them, regardless of where I start, end up at J. Harlen Bretz and mega floods.

Fabulously told story brilliantly compressing the stories of "Ice Age Floods, A to Z" into one evening's presentation. One would think this an impossible task! You've tantalizingly interwoven the geolophysical story of the floods with the very human tale of Bretz and his collaborators as no one else can. Nick, you hit it out of the park again!

Constructive criticism offered with the utmost respect for Dr. Zentner and all the folks who produced this excellent piece. The sound was uneven due to, it appears, the podium mike remaining on while Dr. Zentner roamed the stage. His clip mic was kind of weak with a bit too much echo. That went away when he got in range of the podium mic which produced much better quality sound. The strength of the subject and presentation prevented this from detracting much from the overall effect but it was noticeable.

Great presentation Nick! but, if you had stayed close to the right, board side of the desk mic, I would have been able to decipher about 40% more of what you said.

Nick for president!!!❤

Nick. You know there are a ton of anomalies that don’t fit. Even, and especially, the errant boulders. There are no glacial proxies that I can detect in the videos of yours I’ve seen and the NE I’ve studied intently. I can prove it.

So Enjoy Nicks's talks.. Thanks for this. its one of my favorite topics.

Thank you for a really fine presentation..again!

1:05:38, I’m in north MN and can only assume the widely mixed assortment of rocks in the surrounding fields are erratic glacial debris of some kind. Some are very distinct and seem like they must have a matchable source somewhere, kinda like a persons DNA found at a crime scene.

We probably have most of the pieces of the puzzle we just need more people willing to work together to put those pieces together to see the big picture. Just like in sport you can have great players but as long as they not work as a team little will be achieved. And that's the work of a coach like Nick Zentner to create that inspiration that can move mountains.

To the basic question about where the water comes from (either in Montana or Okanogan) during the Ice Ages... Glaciers melt in the Summer. Not all the way, but they do. Check out the Carbon River coming out of the, uh, Carbon Glacier on Mt. Rainier. Small glacier in comparison to the Ice Age... so very much water in the Carbon River you can HEAR the boulders bonking off of each other in the river. Side note: That would make a great Nick on the Rocks. Don't cross glacial outflow rivers without a bridge, if you like your ankles!

Why not do a segment on the granites and how scientist Robert V Gentry proved in the 1970 s that all granites formed nearly instantly due to the presence of radio halos and his scientific papers still have not been accepted in mainstream . You’re teaching pseudo sciences in the geology field .

What dew we do with this lump of golden coal?_@m ~ ~

Very nice presentation! I hope you get some recognition for putting this together. And a shout out to the army of vollunteers that did such wonderful work recovering the history.

What an amazing presentation. Loved the follow up questions. Thank you Nick.

My favorite geologist. I have never viewed the Northwest the same since I discovered Nick on KZfaq. But, he has cost me a fortune in fuel following his footstep's across the scablands.

Thank you Nick for another wonderful presentation!

Love your videos, Nick. This is a wonderful story of scientific discovery, human community spirit and brilliant minds. Thank you for the inspiring way you organized the study. Brought tears to my eyes. Beautiful.

Nano diamonds and platinum spherical particals found in ice records across North America, as well as native oral history, point towards "COMET IMPACTS on glaciers" as the BIG BLUE water source .

⚘ THANK YOU, NICK ZENTNER. What a caring and conscientious educator!

I am an old man just discovering geology. I have been listening to Myron Cook and now I have listened to a couple of Nick Zentner's programs. Great stuff. Makes me wish I had the internet back in my younger days, but, then, how can that be when I helped develop it in my own small insignificant way.

Bravo - from the Saddle Mt...

It's unfortunate the audio is messed up. His lapel mic wasn't picking up.

Zentner: There were dozens of Missoula floods Randall Carlson: There was one massive flood Please get these guys together to debate.
