As a retired middle school administrator, I observed and evaluated dozens of teachers during my career. It thrills me to watch in real time an extremely skilled educator such as you orchestrate a masterful lesson on a complicated subject. What a joy! By the way, I live within a half hour's drive of the Siletz River and the Mary's Peak remnant of Siletzia.

Keep your home space seperate as a recharge place. Visitors could get tours from the Ice Age Floods institute or teams of grad students could lead teams of the public to interesting rock sites.

we used a field guide in Idaho and Oregon to find the sea coast near Ola Idaho.

Gotta love it. Thanks Nick.

Thanks Nick! You mentioned a subducting spreading ridge @36:37 Naturally, I was hyper ventilating for a few seconds. There is a common assumption regarding strike-slip faults that I don’t automatically subscribe to, and think complicates any presentation- that each side “moves in opposite directions.” IMHO, that would require some crustal accommodation on all four ends of the fault- extension on one side and compression on the other, and visa-versa on the other end, but without a mechanism for every side/end of the fault. I never see the other mechanism opposing the terrane presented, such as “X formation was thrusted and folded Northerly” with opposing arrows signifying the fault directions, but not explaining the mechanism for the other formation’s Southerly movement; many times, there isn’t any, but nearly everyone automatically assumes there is one. A Strike-Slip fault doesn’t require opposing sides; a valid alternative that doesn’t complicate a fault presentation is varying momentums in the same direction. For example, formation X on the West side of a fault moved North 10mm’s per year for 7my’s, while formation Y on the East side of the fault moved North 0-1mm per year during the same period.

Dennis from Boise is listening to the recording today I was out hiking on our ancient sea coast yesterday!

Nick - I noticed such stunning geologic features in the places Noraly is riding... did you know she has a MSc in Geochemistry?!?! Wow!... You gotta love it! : )

Geology field guides - you gotta love 'em!

Our sandbox was the top half of an airplane gas tank, our wading pool was the bottom half. Boeing surplus. But both were rimmed with 2x4s to sit on and not get cut by the sharp edge. That was pre- turtle sandboxes. Turtles had lids that kept sand dry, and the cats out.

Two million years is a long time when you are talking about river directions. We have rivers that have changed direction in the last ten thousand years.

No Sir, Nick. You missed Patrick's point. You stated categorically that Sileztia ignited the Straight Creek Fault. But it doesn't take accretion of a young, buoyant exotic terrane to initiate right lateral faulting. The Cascadia Subduction Zone terminates into right lateral faults on both ends: the Queen Charlette Fault on the north and the San Andreas Fault on the south. Nobody believes the SAF was launched by accretion of an exotic terrane. It may be mere coincidence, but for all practical purposes the Yellowstone Hotspot was located right on top of the spreading center. In this case the accretion of the Hotspot and spreading center were one and the same. Patrick recalls from the reading that transform faults that segment the spreading center are just as capable of igniting right lateral faulting ashore in a case of oblique subduction. From the reading this is in fact currently occurring in Chile where the oblique subduction of transform and spreading segments continues ashore to this day.

Nick, go back to your exotic terranes videos and re-watch where you crashed the round loaf of sourdough into the fruitcake. The whole grand circus played out in my mind when all the pieces of fruitcake moved. I could then visualize the whole fault ideas. Great video if you ask me.

those snickerdoodles are curiously arranged in an anticline fold in the box

watching from a hospital bed, would not miss you for any reason. Whidbey Island, 74 yr old neuro psych

Lol my sandbox was ocean beach sand from Oregon in 2 x 4's up on Lonesome Creek in the Blue Mts of Oregon. I guess it is still there. that was about 67 years ago.

38:00 i love the topic of spreading ridge subduction! I think it’s one of the most fascinating aspects of plate tectonics. would be curious to see if the plate kinematics allow for a spreading ridge to subduct under Washington when the Teannaway basalts and rhyolites were being formed. Good stuff!

In 76 we had a tide table the 60s we had Medow Land Diary

Thanks Ned!

live social and social media is two different things!

Would the West flowing rivers coming into the 'sandbox' from maybe as far as Idaho, only add lubrication and liquidity to the whole rift. I.e. the sandbox became a supersaturated sand/gravel area, easily shifted by the Siletzea collision quakes/afterquakes due somewhat to liquefaction?

The Cascades seem to be a young version of The Appalachians. Very complex geology.

Im at the first rerun ;D Nice one Nick....good job and amazing cookies!

Nick. Sir.. ihave learned a lots about our world from your live streams. WHERE DID THE WATER COME FROM ON EARTH? AND DOES THE OCEAN FLOORS FLOAT?

Ridgefield, Washington checking in.

Would any of that "circus" stuff happened without Siletzia? by just moving west over the Farallon plate?

How do the zircons in the Swauk date it? They may have been formed in another time and just mixed in.

What lovely gift, anonymous

The West flowing Rivers became reservoirs

I did not think I’d get to see a maskless university class this year! Glad not everywhere is anal about them anymore Meanwhile, my uni made us wear masks outdoors, socially distanced, for commencement last weekend

I’d have to say Melange vs Circus

Dennis age 69!

AT 41:36 to 41:50.....TEACH IT AND THEY WILL COME NICK.

Sandbox bit....lol

I’d love to be back in school. But something tells me I wouldn’t just owe 20k after four years these days. I’ll know soon enough though when my oldest heads out in….what, good lord, 8 years!!!

Late to the party but I did make it.

Social interactions with viewers? I think better to keep it arms length, because once you start you can’t stop.

Nick is not been a logger he barely has an idea how to cuss,

... Nick is too nice, he should avoid spending time with geol tourists we would understand, and he has college kids paying $10,000 for education so better them even if they can b monotonous decades of teaching, and researchers. Broadcasting avoids most of this, unless one is too nice. Maybe alumni deserve a little more time .... And with respect the Roadside books probably teach best not a generalist like N. I prob am annoying tourist too in person so can say this ha.

Nick, Good job! I do have an issue with your increasing FOUL language. In any classroom, this is not appropriate. It should not be used in such a public form as this. It is not allowed, or tolerated in the Private business sector. Maybe you need to stop hanging out at the dive bars.
