It’s nice having these consolidated to Nicks channel, I really like his more polished lectures, learn so much in a well paced interesting and surprising way.
I've only had one teacher in 60 years as good as Nick. He was my AP History Teacher back in Pittsburgh. Taught me how to separate facts from fiction (better known as High School History Books). I love history, but I learned more from him in one year, than any teacher before or since the time in HS. Because of him I read over 350 history and non fictions books a year and can separate BS from News. Which is easy considering to lowest common denominator of news, BS masquerading as fact. Something most news channels seem to do. I love Nick, he is what a real teacher should be. Funny, entertaining, but full of useful facts that teach you about the real history of the region and geology that made it.
I want to to a road trip and see all this sometime this spring It’s so great I listen to these over and over as there is so much information Thank youn
Thank you for posting your CWU lecture series to your channel. For a some reason as in EU area, I have experiencin not being able to see some of them from CWU channel anymore.
Would anyone like to see Nicks take on Geology outside of the PNW? Maybe his next series could cover BIG topics that we are all curious about that may even have influences, parallels or similarities to what we have learned about the PNW, maybe that would help solidify ideas here.
In the last three days I have watched four of these presentation s. Zero interest in geology, but this Professor makes learning esoteric information so interesting. Thank you.
A geologists went walkin' out one dark and windy day Upon the rocks he pondered as he went along his way Lava flows he chanced upon but could not find their source No strato peak was evident along the magma's course Lahars had filled up canyons, and cemented in their tale But still a source he could not find, in mountain, hill or dale A bolt of insight went through him as he looked upon the land The cone is gone, he shouted out, ground down into the sand Yipie I oh, yipie I yay, Ghost volcanoes in the 'scades...
1:06:56 When they started talking about the vents, I could certainly see them in my mind having seen the recent footage from Halemaumau in Hawaii. And I could better visualize and identify the features they pointed out as I thought about the spewing vents pouring lava into the rising lake. The feature shown at 1:08:04 almost seems like an upburst of lava frozen in time. It pushes up from the vent and falls away to the left. You can see it is different rock from the surrounding area. Anyway glad to find this "old" lecture.
From your comments, Nick, the glaciers didn't reach far enough down to effect the flows. But from the look of it that "double layer" feels like something that would happen with the flow passing under a layer of ice. A body of water would, oddly enough, dissipate the heat faster I think?
Vulcanism isn't quite dead along the Sierra Nevada. There's Mammoth Mountain, for instance, and all the associated geo/hydrothermal sites nearby. The mountain itself is a ca. 500m prominence a fairly newish lava dome, dominating not quite the center of an older caldera (find a view of Mammoth Mt. with the Ritter Range in the background to get a sense of the scale) that quite obviously ain't dead yet, either. There's ghost trees (more recent) there, too. Due to high (deadly to humans sometimes) levels of CO2 and other pleasant gasses, all courtesy of some still very active vulcanism. It's California's "Yellowstone" or, better, Hakodate.
He mentioned earlier in this video that the Juan de Fuca Plate will completely subsumed beneath the North American plate in 5 million years. How did they determine that?
31:58 What your Referring to is something I like to call a (Stratocaldera forming Eruption ) I know that seems long but let me explain why I call it that my word no body else’s like ghostvolcanoes belongs to you 😂. Anyways a large Stratovolcano has a magma chamber, nearly emptied due to a incredibly long eruption in which a due to the sheer size of the cone the rock above begins to fracture and deep fissures form than the whole Stratovolcano starts to collapse in on a self forming a caldera. Therefore, you can only get a Stratocaldera if you have a Strato volcano in its place before hand. The examples I know well is crater lake Mount Mazama as you said , Mount Rinjani in Indonesian or even Mount Pinatubo in the Philippines on a smaller scale. And my hypothesis on why these eruptions occur is due to the fact of a lot of magma being built-up in the magma chamber, causing a longer eruption, therefore, emptying great volumes of magma and the amount of flank that has grown since a volcanoes last eruption as more size and volume means more weight, causing the possibility of either a huge landslide or a caldera collapse, but I believe a landslide is more likely before a caldera collapse. And as Nick said there’s no way to forecast it, we can only hypothesise , guess and hope for the best.
Professor it is amazing you would post Ghost Volcanoes lecture today Dec 26. because last night I was visited by the Ghost Volcano Ebenezer Zinger and well lets say my future is in question. Were you visited by a Ghost also??? Ned Zinger??? Love the town lectures hope for there return in 2021
These are from the Central Washington University YT site & have been consolidated on Nick’s YT site. That way, you don’t have to pick your way through a lot of “announcements” to get to this content.

This was an engaging lecture. While I’m a meteorologist turned software guy, I think I could have just as well been a geologist.
And I think I could have been a nfl qb and banged a supermodel from Brazil.
As a software guy I dream of being a geologist!
I know several IT people with meteorology degrees... Hmmm
That was GREAT to watch thank you Nick. :)
Excellent presentation. Both informative and enticing.

Since I watch your videos, I see the landscapes while driving in Europe in a very different way…😊

A geologists went walkin' out one dark and windy day
Upon the rocks he pondered as he went along his way
Lava flows he chanced upon but could not find their source
No strato peak was evident along the magma's course
Lahars had filled up canyons, and cemented in their tale
But still a source he could not find, in mountain, hill or dale
A bolt of insight went through him as he looked upon the land
The cone is gone, he shouted out, ground down into the sand
Yipie I oh, yipie I yay,
Ghost volcanoes in the 'scades...
Beautiful
I've been haunted by a ghost volcano,
Ghost volcano
Ghost volcano
I've been haunted by a ghost volcano . . .
And a phantom cinder cone
Really good one, thanks!
It's worth noting that the active volcanoes keep advancing westward, with most of the older partial and 'ghost volcanoes' to their east.
I live south of Mount Rainer. It's gorgeous.

I was just getting a handle on lava flows and columnar basalt and you throw this at me. I might have to watch this lecture two or three times.
Bravo!!

Why is there volcanic rock in Missouri? My grandpa had property in South Central Missouri and all over the property was sheets of volcanic rock.
Now you just made me feel old he Diad way to Young and I am jelles how der he go before me .

I follow a guy who can see ghost volcanoes from Google earth all over
@GeologyNick would this presentation change now that you've changed your mind about the old Farallon plate theory?
Isn't this his lecture from years ago??
New Madrid & E Tn sz's pls!
Any batholith evidence in Oregon?
Has to be older lectures because of the crowd.
Yes, those are public talks from 2019. They have previously been published on the CWU youtube channel.

Although this lecture was filmed in 2018, why am I so concerned about the # of people carrying flu or other viruses.
Yeah I kept wondering about people sitting so close to one another back then.
