[@xwiick]

Thanks for all the hard work on this series too everyone involved!

[@denisee9966]

I'm enjoying this A-Z series SO much! Thank you for all the angles you come from. I love the geologists and their ideas. I love the local stories, photos, and videos. I love everything that's been sent in by the viewers. And I'm a really big fan of us moving through all sorts of spaces and ideas we couldn't have predicted. You're awesome and this community is also awesome!

[@KevinFournier-xd3ub]

Was starting my office hours right at the moment this began, so catching this on replay. Thank you Nick!

[@RockManGary]

Thank you Nick . Another great show. See you tomorrow

[@patmurphey5118]

thx for the slide show, great memorial to Mr. Hammond.

[@kevinjames6189]

Thank you Nick😊

[@yukigatlin9358]

😃Woo, wow!🤣Not sure why🤔✨but, your narrative was intriguing to my eyes and ears!!👏I was on it after all... Thank you Nick, you are the best!!🟢💞🌐✨

[@SteveMorgan-d6e]

Thanks for sharing the joy!🎉

[@rosiealaniz3205]

What an end! I’m not crying…you are crying… thank you Professor Nick! Rosie from Dallas, TX, y’all

[@anaritamartinho1340]

Thanks for this awesome series🎉❤

[@guiart4728]

Another awesome edition! Loved that satellite shot of Mt Rainier blasting up through the Ohanapecosh mixture of volcanic and sedimentary basin deposits!!! Light bulb moment for me! Thanks!!!

[@hbrameus]

As always a great episode. I think it’s the first time I’ve seen Nick wearing 4 shirts, though. Shirt, puffy vest (?), shirt, and sweater. I’m impressed! And I wonder how cold his office is.

[@sharonseal9150]

Loved the episode as always Nick - I like that we are weaving in the past geology stories you have presented with the present narrative. I plan to have a lot of fun with the geology coloring page and supporting documents. A big thank you to Morgan Salisbury! I regret that I did not think to ask today about the locations on his map near Wenatchee that are designated Ohanapekosh - that was a HUGE surprise! Hope to learn more about that.

[@Just-W]

So glad you revisited your take on the Kula Plate and SCF connection - I thought that's what you were getting at on the last episode, so it was good for my brain to get the (re?)clarification. Thanks so much for putting this all together for us!

[@AmyBraden]

OMG such great memory flashbacks from the song. ❤

[@nohandle257]

I picked up on the mica thing. I grasped the concept as I know how large mica flakes can be. However if you've got rocks with 'reworked' mica . . . they're been chopped up or ground to a smaller size by hydrological, riverine, processes. These presentations are hard for me to follow and I'm pretty interested in geology over the decades. It helps to digress a bit for time to time, as you did, for the peanut gallery. 🙃

[@johnnash5118]

Nick, Thank you for your valuable time trying to answer my rushed and ill-constructed question. My live chat question was “WAS THE NW ROTATION VIA A CHANGE IN SUBDUCTION ANGLE OR WAS IT A PHYSICAL MOVEMENT OF THE TERRAIN, SUCH AS THE TRANSVERSE RANGE?” I should’ve included “approach and vector” to clarify what I meant as the angle; it caused you to think subduction descent angle, which is exactly what I would’ve interpreted. It should’ve been read as “Was the NW rotation via a subduction approach vector angle change i.e., toward the North-NE to East-SE; or was it a physical movement of the paleo terrain such as the Transverse Range?” The Paleo arc would’ve been oceanic South of WA and in a NW-SE orientation toward pre-extended Eastern CA., now in NW Nevada; but as the NA plate subducted the oceanic plate, offset by offset, the vectors would change due to the opposite orientations of the associated spreading ridge. That would‘ve be chaotic for the paleo arc because of the changing and stair-stepped vectors of the stair-stepped oceanic plate offsets.

Viewing from Mt. Vista, WA, 80 miles sw of lovely MSH.

Room 222! I remember that show.

[@wildwolfwind6557]

Lovin' the rainbow❣ If the very start of the San Andreas & the Queen Charlotte / Fairweather faults were ~30 Ma and the movement of NA slowed between 20 & 30 Ma (from the Vic Vamp / Idaho series video), could the initiation of the San Andreas & Queen Charlotte / Fairweather be associated with the slowing and/or be associated with the volume of volcanism (Ohanapecosh & Chilliwack)? If there was a higher rate of convergence for the Kula plate after initiating the Cascades, could it have been similar to the convergence of the Queen Charlotte / Fairweather increasing in the past ~6 to 12 Ma with under-thrusting? 💖💞❣

At some point, can you present diagrams of the sea coast locations from BC to OR as a function of time from 50 MY to now?

[@spamletspamley672]

Liking this 'Expected Dextral Boundary' diagram. Looks to me from this, that there can't be an actual driving force in the direction of the arrows on the Farallon plate: this 'force' must, surely, be the reactive force against the continental plate being forced over the Farallon because it is locked up tight against the Pacific. (How does this tie in with the weird pattern of trenches over the isthmus, in the Caribbean, by the way?)

I hope there were no dead flies or dust bunnies in that owl mug.

Firstly, these Groups are named after the area i presume, however, does it help anyone to have so many names for essentially the same Rock Formation? Maybe its better to "standardise" these formations. A mission for someone, somewhere, sometime? Referring back to Megan Andersons video, this makes great sense, The in or out of water at 50/30 ma.? I think its relative to the regional topography at that time. Ok now we look at the Plutons within Batholiths, questions, how high, toward the surface, did the Plutons within the Batholith make it? The reason for not actually reaching the surface? Be it the over riding Rock composition or lack of pressure/heat from below? Do we actually now what depth all these Pluton/Batholiths were at specified times? That info could contribute to the "elevator" "effect" that enabled so many large rock formations to rise to the surface so quickly in Geologic time? As Mr Zentner says at times, I don't know what i'm talking about, that's me, always.

[@nohandle257]

Just an aside: What's the deal with four layers? You keeping it cold in your office on purpose or is the uni saving on energy costs?

[@itakephotos1141]

Dementia sucks. It breaks my heart. I hope that one day a cure or a treatment to keep it at bay.

[@paulbrallier7028]

Got to watch the whole Chris Mattinson video to see the jump in the green M&M

[@ofb1583]

Are there geological processes in the pacific time zone that result in different colours in your rainbows as opposed to the rest of the planet, like brown?

[@kellyhorton1462]

Hello Prof Z

[@JanetHouck-h5h]

Spencer Creek near Kalama?

[@fez3606]

HEY! I went to PSU...too bad I wasn't studying Geology.
