I've been a geologist a long time (near 70) but had never heard the world "inlier" before, but it seems appropriate. When you showed the geologic map, to this "trained eye", what you ultimately circled (the green) leaped off the page. Fascinating stuff. That green "stuff" may only be Mesozoic in age, but sure looks like stuff that has been deeply buried, pushed and squashed into a near green schist (while bumping along the subduction zone???)... complete with the quartz veins showing the temp/pressure of burial and lots of hydrothermal / aqueous activity. Sure beats the pancake stratigraphy of the Illinois Basin.

Just a quick note about radiolarians, which evidently make up that chert deposit: Radiolarians are marine phytoplankton, essentially a very fancy amoeba that secretes a silica shell. The shells sink to the bottom when the radiolarian dies, and if they're abundant enough, they can accumulate as a "radiolarian ooze," which hardens over geologic time into the chert.

I like Nick you can tell his love and enthusiasm not only about geology but also his love of sharing this information. I find it really positive especially in our weird existence today.

So right!

I love that you think out loud! It helps us learn. And makes you real person. Just sent link to my whole family (rock lovers) for them to learn along with me! I’m a huge fan!

At 27 minutes "flowing towards the Fred Meyer in Yakima". Funny yet a great way to help those that are near there visualize it.

I can listen to You, all day long. I am amazed by the amount of geological events, that has happened just in the Northwest.

Frickin gorgeous area, Nick. Thanks for sharing the beauty & the knowledge that helps us appreciate it too. You're an actual gem yourself. Bless you sir

Another great field trip with Nick!! I just love these. I feel like it's just me and Nick out there crawling around and busting rocks open and enjoying the great Washington outdoors. Always learn so much and love every minute. Thank you again our beloved Nick!!

Nice picture, its got a Bob Ross look to it....makes me want to get the oil paints from out the attic.

Thank you for your powerful creating 🎉🎉🎉🎉❤😊😊😊😊😊

Dear Nick, thank you for doing all the work for us! I am finding it's easy to be a sponge, loving every revelation of this wonderful creation!! Thanks so much

I haven't sat in a college-level classroom in 40+ years. Nick makes me feel like should have been doing this a long, long time ago.

Nick, to me this is the best work that you have done. 99% of this is new to me and I want to go read Bob's full work on this. Just Amazing and now my wife wants me to take her to Rim Rock Lake

Nick it's fascinating to look over your shoulder as you puzzle out the rocks. An old-time (older than you, buddy!) UK geologist, I've found Nick on the Fly an incredible introduction to Baja BC. Your summary at about 20 minutes in is masterly.

Absolutely brutal with the insults to the Indian Creek unit. Great video professor. Love learning about these exotic terranes with you

Thank you Professor Nick!

So interesting there is an outcrop of some very similar appearing bedrock at Rocky Point on the west side of Whidbey Island.

We've been to Rimrock Lake a few times with family. Never looked at the surrounding rock before you, Nick. Mostly the lake and recreation. I'm going to have to Google "rotten rock". You might have explained before but I missed it. Thanks again!

Love your vids! This took me back. Halfway through, it struck me that the area was very familiar, and then I realized that the hubby & I were at Rimrock Lake & stopped at several points along it on a trip through WA & OR in 2011. Looked back on my pics & took some of the rocks along the cliffs there, as I've always loved seeing the different geological features we travel through. Wonderful to get this in-depth explanation of what's really there.

Thank you Nick, this is such a picturesque location! And the geology in very interesting. Every time I hear "veins of quartz" I can't help but think of gold. The Schmidt Ocean Institute runs an ROV from the RV Falcor, which they use to explore the deep ocean floor. They frequently have geologists that comment on what they see, and viewers ask questions and participate. Currently they are exploring the deep water between atolls in the Coral Sea.

Green rock with nice quartz veins... there must be gold up there somewhere! I love those green pillows. I love these day trips. That lake is such a beautiful blue and the surrounding scenery is stunning, the topics so interesting... just love all of it!

Thank you Nick for your continued wonderful videos. Fascinating.

Oh, I get it now, not reading and digesting the paper beforehand but using it to back up your observations is what you’ve been intentionally going for. That’s really refreshing and a fun way for us to learn along with you.

It took me a second to figure out why you were only using one hand to break the rocks. I really enjoy your videos. I wish someone would do what you're doing in New York.

Some of my most enjoyable outdoor time, was spent there.

Thanks --I love the exotic terranes.

That's awesome, I had no idea Rimrock area is that old. Thanks!

Thanks for sharing your joy of discovery as you figured out those green pillow rocks.

Hope someday I can visit some of the terrains and terranes that you've been able to show us. And have a beer with you!

Missed the initial broadcast, had to fix sons AC, 80* in his house. But loved the pillows\green rocks and your not feeling bad about looking dumb. Ask me and I know my answer is dumb, that's why I watch you, I'm learning from those who aren't afraid to take a leep. Go Nick!

Excellent, again. I learned loads, again. Thank you from Jane in Hereford, England.

ANOTHER HOME RUN!!! Love your honesty and excitement, keep being you, it is refreshing especially these days. The second outcropping looks a whole lot more lie serpentine especially with the red next to the green and black, BUT, I really know nothing.

Prof Nick, Love the lecture, thank you for taking the drives /travels to learn about and discover new to you and most of us about the RockETerranes in Washington!

lol, how can rock be rotten and a disappointment to it's parents?? lol. It is pretty there. Where is everyone??or anyone? No birds either, one butterfly.

I wish I could just drive around Idaho, Oregon and Washington with you riding shotgun to tell me just what and the hell I'm looking at. The geology of this place is like a bowl of spaghetti!

Man...i missed this channel, got a lot of catching up to do...I appreciate what you do Nick, I got into your lectures a few years ago... have missed a lot of content apparently... i was in western Washington then. I am in southern Idaho now....lots of great geology here.....hint hint

Woooooeee,,,,, that looks like one heck of a fishing hole !!!!!!

Basalt lava (amygdaloidal) This is a basalt, a dark coloured volcanic rock formed from a magma of basic composition erupted on the Earth's surface. ... Filled cavities in lavas are called amygdales, and a rock full of them can be called amygdaloidal. The amygdales are usually white in colour.

Thanks Nick! Another great field trip - very interesting as usual! 👍👍👍

So refreshing learning on the fly this way. Thank you Nick.

"Plutonic rock that's a disappointment to its parents " Nice

That looks pillowey!

A while back you showed a picture of enumclaw talking about the Osceola mud flow in the background there's Mount peak or Pinnacle peak halfway up and close to the top there is lava shaped like beehive cone

Thanks so much for putting together the whole exotic terrane story for us! It all clicked when you showed the map of the straight creek fault. Interesting question about whether it continues below the Tieton andesite. Wonder if anyone is working on that??

At 47:43 across the lake is a cliff with dark gray and light gray rock with a seemingly sharp line separating them. Divisions like that would pique my interest.

Nick just made a significant statement here about what makes a person real: "I'm not afraid of looking like a dumbass." WOW! I LOVE that sentence. Would that our nation's "leaders" could say that! Whatever, I'm making that one of my life principles!

The plot thickens... The evidence is not that clear cut but very interesting. Thanks Nick!

Thenks.

Thanks nick

You would have stayed by the lapping water sound at the end, and I would have slept through your "good bye", lol

Interesting that the pillow appearance could retain that appearance thru many many millions of years of extreme heat and pressure ......

I will have to visit these pillows... I

Nick on the wild wild west side of the Strait Creek Fault.

In another week, Rimrock Lake starts getting released and the river rafters are out in full force on the Tieton. Gets busy then. Wish I'd known some of this the last time I was there.

I like your paper geologic map at that scale. Do you have a source of them for us lay people? I know where to find them online, but it's tricky to print them at large scale and with such quality. Thank you.

Don't worry about it, I'm walking right behind you too.

Is the green area, the Mesozoic bedrock, being pushed up to the surface by the broad underlying forces creating the Cascades, or is the river systems in that area eroding down to the bedrock level?

Video time 43:40 - Freeze and thaw weathering, looks like rottenstone, to bad you couldn't get a core sample, let's do this again

My wife and I were at that same spot several weeks ago taking samples and trying to figure what it was.

look at the show off!!! what a beautiful place :)lol I know I will through my deck and hammer in the car and head off :) yep show boating of the highest order :) ok there's good geology stuff too, but I know what your up too!! :) :)

23:05 Thanks for thinking out loud.

Thanks Nick . Have you ever check out the blue hills in Barron ,Rusk county Wi. north east WI

*PALEO FAUNA ALERT:* That outcrop (or is it? 🤔) in the upper right corner looks like a stegosaurus wading through grass to get to the lake.

Pillow lava.. . Eruption injected lava into the sediments and water of a significant body of water.....very slow process allowed for rapid/consistent cooling

❤

I tried to sleep on a mesozoic pillow; but, it was not very comfortable.

There is a big prominent fault running N/S visible just north of rimrock lake on multispectral imaging maps I have done. Probably the fault you mentioned.

Amygdaloidal refers to or containins Amygdules which are in filled cavity's of lava rock usually from low temperature alteration

42:11 "you're under arrest for crushing and smoking mesozoic rocks for *illicit* purposes!"

Nick - Watching you bust open rock after rock looking for a fresh surface, I started to wonder how much these "On the Fly" videos exist just so you have an excuse to hit things with a hammer... ;-) Cheap Therapy? Happy that we all get to benefit from it!

What was cone shape across pretty blue water near the end?

I have some samples I’d like to show you that I dug out of the layers of the coulee wall by grand coulee when I was a kid

what you need is a Smartphone with a direct app to an "Encyclopedia Geologica" with details and lots of pictures!

There are numerous outcrops around the lake. Are they exotic terrane too?

Could it be pillow lavas that retained their shape but do to intense pressure been infused with quartz?.

Okay just to be clear, the greenstone pillows were on which road? Where do I go if I want to see them?

Bravo ! Comrade! ..story ideas : I like metiorites - a survey..the campus rock collections , ,slabing a stone , ..what's in a classroom to help learning..where to get sciency maps...zicron testing for 55 $...how is the sample prepared ," preped "...how to handle acids , how to request chemicals from the chemestry Dept. How to i.d. a zircron in a metiorite.also pallasite metiorites have green crystal s peridot / olivine, how would you reseaRch that mineral ? Green laser looking for green crystal s..might it glow ?

could that 'green' stone be green as in new or fresh in the meta of the morphic? are there color blind geologists?

That broken up formation at the end next to the lake has sections that looked burned. That could explain the greatly eroded nature of the entire formation. Past forest fires?

Don't believe it is "burned." The orange brown everywhere is just "rusty" alteration products along shattered rock fabric planes. (I hesitate to call them "fractures.") There are plenty of real fractures and shears visible but these rocks are smashed and corroded on a complicated fractal scale around the mineral rims and break where the softer metamorphosed clays and micas (phyllosilicate) minerals have been weakened by simple weathering and chemical alteration that are way more than merely "skin deep." And this is why it is impossible to get a fresh clean cut mineral surface in this rusty regolith. When deeply buried and discovered with the drill bit these rocks get labelled "detrital" or "Granite Wash."

I'll bet you're one of the few people in WA that can say olympicgolowathingamajig. Greg in TN :)

Mu first thought was they were under water pillows when formed!

Do you realize how many times you say "I'm not flipping you off"? It doesn't even occur to me until you say it. I think you are too used to working with young students :o)

I thought it look like pillow lava before you said the same

Radiolarians are/were small zooplankton which form a silica skeleton. When they die, the skeletons fall to the ocean floor. Over a lot of time the layers of ooze are pressed into rock (a type of chert).

Are these papers available to the layperson, and if so, where?

I wanted more connection between what I was looking at after the hammer struck and the bigger "Baja to BC" picture, but I'm neither geologist nor geology student, really. Having been to Cle Elum years ago, I mostly enjoy the scenery.

@@bagoquarks The problem with that idea is a Milwaukee power hammer is 63.9 lbs. So freakin' big it comes with it's own cart. An Estwing sledge hammer comes in at $29.98 and 48 oz. (one hand), and $39.98 and 10 lbs. (two hand). Plus, that $350 price tag for spare batteries is for the 1/2 size 3 amp hour cell...the full 6 amp hour pack is $599.

“Window” is profoundly relevant to study the basement of the NW, as these windows are what hasn’t been buried by more recent formations; these are not islands, they are connected under the newer flows and intrusions.

Nick don't be biased now. You should occasionally say sorry to the other children rather than singling out Patrick.

Do these guys (Bob Miller) know you are breaking down their papers now in real time?Lol Nothing like a few gazillion year old ancient formations to make you feel like a smarty pants

Some ugly ruck. Nick can you ex-plane why Siberia was not frozen during the ice age.-
