I am enjoying your lectures on the geology of Utah and various area of the west. However, for your slide on introduction to optical mineralogy, showing both electrical and magnetic waves, you have a significant error in your diagram. You have the crest of the electrical wave coincident in time and place with the crest of the magnetic wave. Since the magnetic wave is generated by the electric Changing field it needs to be shifted so that the maximum of the magnetic wave is at the crossing point of the electrical wave. This is the reason that it is able to travel in space and is required to go exactly the speed of light, according to the definition of how changing magnetic fields make electrical fields and vice versa, cheers!
I can't believe there aren't anymore lectures. How am I going to psych myself up to teach Summer School Earth Science without my daily dose of geo-smartness? Thank you so much, Dr. Naumann. You absolutely helped me remember why I love geology. Much love from Upstate New York.
25:16 arent those the White Mountains??? I remember my professor said it said to part of the Sierra Nevada mountains at some point before it was split.
currently on a break between the semester i took mineralogy and the semester i’m going to take petrology (and more mineralogy). your videos are so helpful, you explain things so well, and are so. much. Less. intense than my mineralogy prof. thank you for the uploads, i seriously appreciate them so much!!
Have you seen the evidence that plate subduction at a shallow angle isn’t what caused the Rocky Mountains? But instead a stationary micro continent was in front of the advancing North American, plate 80 million years ago? How does this change the history listed here?…
I can’t say that I understand this video. But then I don’t understand the bond market either. Thanks for the idea that something broke in 2007. Will study.
Mr. Neumann, my wife and icamped at totweap thenanother tripwe camped at kanab point and came across two uranium mines, which were interesting. Enjoy your videos.
I keep coming back to this video! I wanna go on the field trip!! : ) I've been visiting this area all my life and it's so nice to get an understanding of the geology behind all the places I visit. It's kind of like being able to put a face to the name, if you know what I mean.
Renewing an interest in geology. Very familiar with the area, but not so much with the geology. I've often wondered if the Colorado River cut the canyon, or was it a rift canyon?
What a solid educational presentation! Your lectures are a wonderful gift that tell these geologic stories with remarkable clarity in words, concepts, and graphics.
This was fantastic. So many features I see in and around me at Lassen Volcanic National are resonant. The Eastern Sierra is "Disneyland" for a geologist. Than you for posting this.
Could Long Valley also have something to do with the Walker Lane? Maybe you have magmas from the higher rate of extension, with the Walker Lane providing conduits.
Not connected to the Walker lane, but related to it by one fault. Walker Lane doesn't run through the Owens Valley, but veers East, North of Mono Lake through to Death Valley until it end at the West to East Garlock Fault Zone. There is a geologic paper on why the Long Valley Caldera was formed and the Walker Lane fault system was not the cause as much as just being pulled into the Eastern Sierra shear zone. Keep in mind that many present day fault lines didn't exist before the VEI 8 eruption 760,000 ya. The area of what came to be known as the LVC was twisted around causing the weakened crust suitable for a large magma chamber to form. The following is a quote from a paper dealing with it. It is a bit complicated, but it goes into the history rather well. I provided a link at the bottom if you're more interested. "The tectonic interaction between the Eastern California Shear Zone and the Walker Lane system localizes volcanism at transtensional pull-apart sections in the Mono-Long Valley region. Long Valley Caldera is located at the western end of the Mina Deflection, a broad zone of northeast-trending left-lateral faults that form a right jog in the regional right-lateral fault system of the Owens Valley providing a link to the Walker Lane to the northeast (Figure 3)" cgec.ucdavis.edu/wp-content/uploads/final-trip-guide-2011.pdf Here is a link to the Walker Lane Map of it and a summary of its history. I also want to warn folks of articles that warn that droughts may cause the Caldera to erupt for the rankest most bogus pseudoscientific tripe I've seen because they have to make Climate Change more alarming. So there are peer reviewed papers claiming drought causes super eruptions. Don't pay attention to them. www.researchgate.net/figure/Regional-tectonic-setting-of-Long-Valley-caldera-CA-NV-The-caldera-occurs-in-a-region_fig5_26644825
Before the eruption over 700,000 years ago, was there previously a mountain in the location where the caldera now lies, which was dessimated by the eruption? Thought I read that somewhere.
Your misstatements are increasing. I will not be watching anymore of your videos. I hope that class went well. I wish you did not have such loose lips.
Lake Lahontan ring a bell? I have been watching your presentations in order and the number of small, but annoying errors are increasing with each video. Overall a good presentation, but you could have used some editorial oversight with your presentation.
You keep saying Bryce Canyon National Park when you mean Cedar Breaks National Monument. This has happened in multiple videos now. I won't comment on the other minor errors that I have seen. Reason: this is overall a good presentation, thank you.
In your slide on index of refraction, you have inverted the speeds. You have velocity in mineral / c which will always be < 1.

Uhh uh uhh uhh uh uhhh Made it 90 seconds
I’d love to know how Sand Hallow was made!
Thank you :)
Any luck finding lost cement gold mine near deadman creek?
Really good for refreshing mineralogy through English
Im surprised no Alabama Hills…
25:16 arent those the White Mountains??? I remember my professor said it said to part of the Sierra Nevada mountains at some point before it was split.
My geology professor said it erupted around 760,000 years ago… does it really matter in geologic time scale?
Terrific overview of the geology of the Las Vegas area, thank you

Other geologists have referred to the alcove as an arch, so it's confusing to hear that you claim that it's not an arch.
Moe-No Lake. Named after the Mono Indians.

You murdered my entire family , thats a fact

Thank u !
dude ur awesome i wish u were my mineralogy teacher instead !!!! thank u for saving me for my exam on monday!!!!

Excellent!
What a great field trip! Lucky students
Great lecture! I envy your students
Like 👍 for panting dog😂
Thank you for information

it was cut no rifting
Enjoyed your lecture, however you're little confused on direction of east and west. An easy error to occur.
Hi, dear respected please send your WhatsApp number,I want to know zoogeography related knowledge from you,thanks
What a solid educational presentation! Your lectures are a wonderful gift that tell these geologic stories with remarkable clarity in words, concepts, and graphics.
*me watching this totally not related to my study field video drunk at 11pm* oh yes education that's what I do that's who I am
I miss your videos! one of the best on TH-cam T_T
Thank you for the "overview".
Good presentation and explanation. Cheers from the other side of the pond

Great video I grew up in mammoth lakes. Only thing I need to add it’s pronounced mo-no lake not mon-o lake.
Before the eruption over 700,000 years ago, was there previously a mountain in the location where the caldera now lies, which was dessimated by the eruption? Thought I read that somewhere.
Thanks! Great info!
Great lectures. I'm really enjoying them.
