I'm incredibly impressed with Nick's ability to break down high level and granular content - and to be able to articulate details clearly and memorably. Thank you so much Nick.

A big thank you to Dave Katleman of San Mateo! What a blessing for Nick and us! Nick, I like the new camera and the view of you and the chalk board. Sound is great. Thank you, Bob! Loud and clear = 5 x 5 5 loud (volume) and 5 clear (intelligible)

Sweet of you Dave and Bob of Seattle. We all need more heroes these days! Thanks for being so very Wonderful!!! And making me tear up watching big hearted Nick tear up! You could wear a shield Nick, the risk is NOT worth it...

Thank you Nick. You are a treasure.

I learned to fly fish in the Yakima in the 80s. I always thought the river just found a crack in the ridges and worked it's way through. Now I can see that was totally wrong. Thanks! I really enjoy your presentstions.

Thanks so much Dave!!! 😁👍♥️ you rock!!!

Glad I'm getting closer to heaven, my mom would be glad to know church worked! Plus we're only 200 feet above sea level, Mississippi runs closer to the mantle and slower than Colorado.

This lecture led me to look up the geology of Stone Mountain (Georgia, USA). Sure enough, it's part of that North American/African continental collision and separation story. This series and Nick's other lectures have really expanded my understanding of Earth's history and processes. I've enjoyed every minute of what has been, at times, a pretty intense education.

We now to the incredible kindness of this wonderful community. ❤️🙏

Missed the live part.. to many distractions today.. But I got it this evening.. I am learning so much and that is saying something! thanks Nick.. You truly are a good man..

The new camera looks good Dr Nick!!! Thanks for what you do - A townie 🤪😎🤘🤗🙃🙂

I took geology 101 back in the spring of 1987. It’s fun to see how much has changed although I’m not sure how much I remember of the old class. Thank you for letting me take this class all over again and for free!

Thank you Dave 😊 💓 and thank you Bob all the generous and love is so appreciated.

Love the new camera! Nice quality & focus. Might have to get one of these for the zoom lessons I teach.

I learned a lot today - I had no idea the Mississippi flowed the other way. I've taken Physical Geology in the early 70s but this is much better. I'm a Houston guy but spent two months tracing the Glacial Lake Missoula floods all the way to Astoria. I wish I'd had these lectures back then (2013).

You remind me of the best teachers I had - curious about what the next episode will bring. Thanks!

Everything is great in replay. Good to see you enjoying yourself.

Nick: Visibly welling up The rest of us: Not noticing as we ourselves are welling up.

The new camera is so very clear it looks great!!!

Helped out the book store more by making the book available then if just the students bought it! I love it!

Excellent presentation. Thanks for letting the public observe.

Watching this video again, 3 years later. Delighted to review the material and also appreciate the continued developing of a master presenter in professor Nick. Best part is how the overall presentation is not necessarily more polished(although truly better) but the spirit and personality of Nick at work(how do you call something that he loves to do work?) still So engaging. Bravo Nick!

Bob and Dave, you guys are awesome

Thank you once again Pro. Zentner

I knew that rivers meandered, but I had no idea that such dramatic changes happened so quickly. I've been learning a lot. Thanks again!

1:12:55 - Recall the home lecture that talked about the Columbia River and how its route has changed due to the basalt floods in eastern WA.

Thankyou professor Zentner,great video as allways,and for any of my fellow townies interested in learning a unusual fact concerning my home state of TN and the Mississippi River,Google - The creation of Reelfoot Lake,and try to imagine a portion of the Mighty Mississippi river running backwards,i enjoyed class today and wish you all a good evening.

Thanks for another adventure in learning, Dr Nick! Apropos of nothing in particular . . . for mental acuity and general energy, many people have found lipids to be superior to glucose (we can and do use both, but glucose is used preferentially when both are present). In fact, a lifetime of glucose fuel predominance can cause a hormonal dysfunction wherein various tissues do not respond normally to insulin signaling. See Bikman's "Why We Get Sick".

Thanks Nick

Speaking as an old, retired high school social studies teacher, my conclusion is that specialized language is the way EVERY profession limits the membership in its club. Also, rough water discharge figures: Mississippi 1,300,000 ft3/second; Colorado 500,000 ft3/second. Mississippi discharge not quite triple that of the Colorado. And a humble suggestion from a non-geologist to illustrate the interaction of uplift and cutting: The Black Canyon of the Gunnison River in western Colorado. It's now a national park.

Thank you for the lecture prof

excellant lecture !

Hi, Jaice Jones. You asked several questions, but I could only copy one, so here's one answer for "​So does that mean that rivers can only cut into the earth if - essentially - the earth is pushing back?" A river cuts into the earth when the water velocity is fast enough to move the earth it is flowing over. The faster the water flows (i.e., the steeper the slope), the faster the cutting happens. Uplift does not have to be happening for cutting (erosion) to be happening. Remember the video Nick showed of the Mississippi River changing its course over a period of about 35 years, cutting into its own banks? That is erosion without uplift. I hope that helps.

Not worth it in 1080, crystal clear picture on DSL here in Billings. Great sound. Thanks DAVE! Higher broadcast rates might cause more buffering problems for some people.

If a lift is sudden or made of water like ice it can block a river and form a lake, and it will cascade over the lowest place as long as the river itself doesn't freeze. If the ridge lifts a foot a century and the river is 10 feet deep it is not a problem washing away that foot of uplift. There probably some limit on meandering and the ridge is undisturbed beyond those limits. The Midwest also has river flooding and soil deposits, and somehow these deposits fill in whole states like Iowa, Illinois, Indiana, probably has something to do with the ice sheets flooding and deposits given the edge of the sheet happens to have been there.

Imagine the Mississippi cutting down into the ground like the Colorado. It would arrive at the gulf of Mexico thousands of feet below sea level. Not going to happen. (Sort of the hot wire through butter analogy you presented.) I think of rivers on flat ground directing their eroding power laterally (into meanders) instead.

Yakima canyon is a cool place to visit.

(note to self- watch the entire lecture before commenting and you will embarrass yourself less) nobody is upset because nobody missed third person Thursday! nobody will cancel all plans for Thursdays, now.

No No, the Colorado absolutely has meander also within the Grand Canyon, they are not as dramatic as the Mississippi/Yakima (look at Google Earth to check it out). Cheers, Mark ***********************************

From an earlier Yakima River Canyon lecture I learned scientific definition of 'Meander'. WELL ACTUALLY PROF. "Z" NOW The Grand Canyon is part of the Colorado River basin which has developed over the past 70 million years, in part based on apatite (U-Th)/He thermochronometry showing that Grand Canyon reached a depth near to the modern depth by 20 Ma. A recent study examining caves near Grand Canyon places their origins beginning about 17 million years ago. Previous estimates had placed the age of the canyon at 5-6 million years. ***The study, which was published in the journal Science in 2008, used uranium-lead dating to analyze calcite deposits found on the walls of nine caves throughout the canyon!!! There is a substantial amount of controversy because this research suggests such a substantial departure from prior widely supported scientific consensus. In December 2012, a study published in the journal Science claimed new tests had suggested the Grand Canyon could be as old as 70 million years. However, this study has been criticized by those who support the "young canyon" age of around six million years as "[an] attempt to push the interpretation of their new data to their limits without consideration of the whole range of other geologic data sets." There are Meanders in Utah a part of the Colorado River near Moab and near the confluence with the Green River and Colorado River. There are exceptions to the rules or the Geologic Scientific Studies.

There is at least one meander on the Colorado: en.wikipedia.org/wiki/Horseshoe_Bend_(Arizona). Am I wrong Nick? Great course by the way. Thanks for it!

Specific to the camera -- much better resolution and dynamic range. The new camera fixes your lighting problems. White balance is also much better, so you're looking a lot less sickly today.

I am crying for you! Well done everybody... Laughing too...LOL The new cam is way better focus, depth and color concerns are gone. A very few overloaded mic moments but that's just you gettin' exited. The whiteboard cancelled any benefit gained by the camera. It generates a very pronounced exposure and chroma correction, very distracting. Lastly any plane you place in front of your voice always creates issues with the mic. The reflection amplifies the sound pressure level at the mic.

Why is the river straighter before and after the Yakima river canyon? Wouldn't there be more meanders in the other parts of the river?

@CrooningRevival365

I’m going to hypothesize two options: A: there’s a lot of farm land and humans tend to hate river meanders. Army corp of engineers might have straightened it back in the 30s. This was extensively done in Texas where I’m from originally. Consulting an early topo map may prove or disprove this idea. B: after uplift the slope of the land was no longer conducive to forming meanders, but the ones that were in rock were ‘locked’ in place.
