I just drove to Omak Lake, Then Lake Wenatchee, Twisp, Brewster and I live in Chelan. I have met so many people who say they follow you, One said he saw you speak at the Chelan museum..sorry I missed that. Geology is a new found love thanks to you and what a place in the world to live! Thank you for your videos.
Like many of the folks Nick interviews, Ralph seems like a really nice guy who has a HUGE amount of knowledge. Thanks to Nick and Ralph for spending the time ! 😊
Dear Nick. Sometimes I create notes but they disappear into the air. I just want to tell you how much I have been enjoying your spontaneous mountain climbs. Pictures are so beautiful even for these old eyes. I have been worried about your brearthing but when you slipped in a word about your balance as you were moving down a pretty steep mountainside. I hope you use a couple walking sticks..Please be careful and /Love you too
Thanks to Nick and Ralph. My ignorance of the syntax of geology, leaves me wanting to learn more. Nick and Ralph seemed to be enthralled; there on the balcony, in the smoky haze. I was enthralled as well. I wonder where the "gold spike" of the Baja BC line will be driven in? From watching Nicks work I have really been able to follow along and the Baja/BC theory seems to make some sense to me!
There is a feeling early in one’s schooling that “everything has been discovered, and there is nothing left to do.” When we listen to programs like this we get the barest glimpse of how much there is left to discover. I guess one thing that could be said to new students is “This stuff is ALL waiting out there for YOU to discover, your mission in college is to acquire and develop the knowledge and tools to enable you to go out to the field and start filling in the blank parts of the map., and there are a LOT of blank spots on the map. It truly is the “Wild West out there!”
In the last couple of days, I accompanied my friend with his Jeep from Cashmere in the Chumstick, over Entiat Ridge, over the Chelan Mountains, down to Lake Chelan, around its southern tip, then back up Cooper Ridge on the east side of the lake, down into the Methow River valley and Carlton, over into the Methow orthogneiss, then all the way back across Hwy 20, across the RLFZ and on down across the Straight Creek, and back home this evening, to find this waiting for me. Mind blown! Great episode and yet another set-up for Baja-BC!
Having to catchup on your great geology video classes, just returning from Red Cross shelter volunteering due to terrible wildfires in SoCal. I really need this escape from the devastating fires in our regional mountains. It seems the whole West Coast is burning, WA, OR and CA. Thanks for the wonderful diversion.
Ralph Hagerud is both quite enthusiastic and knowledgeable. As he said, it is very complicated. It was a pleasure to see both of you trying to untangle the geological mysteries of that area. I hope he comes back to the show !
My brain just exploded!!! The knowledge of all the geologist that Professor Nick brings into these discussions is mind blowing to me. Especially their recall abilities, I am dumbfounded shaking my head. Thanks again Professor Nick, so happy for you that you have these close relationships, With so many people to enlighten us all.
Your act of kindness/love during Covid shut down has led to so much sharing of knowledge and creative thinking and bringing together so many geologists and theories. There is no telling how advantageous this will be for geology discoveries. How marvelous. You are the perfect example of how acts of kindness and love benefit out into so many areas, like the rings that expand out from a stone plopped into a pond. Namaste and thank you.
So much of this is extremely helpful. Especially when you bring the conversation back to ground Nick. Just showing the faults made sense of the map! Agreed, more viewings are needed. I'd love to have that map. As a Plan B this really worked for me. Thank you Ralph and Nick!
When Ralph gets going, he's speaking Martian to me, a non-geologist, but it's still fun to listen in and glean an occasional nugget from the conversation. Enjoyed my brief stay in Wenatchee in late August - splurged on dinner at Visconti's Italian - as an overnight between checking out Frenchman Coulee and Moses Coulee. Different kind of geology.
Now, that is an awesome map. The feature density is mindblowing. But Ralph's explanations are massive too. The petrology is just as, well, brain candy.
Wow! Thank you Ralph and Nick. Interesting! I'm able to follow a lot of this (I think). So the Crystalline Core may be a metamorphic core complex associated with transtensional (being pulled by a strike-slip) faulting that was also moving north. A lot. Explains the 'elevator' moving up. Plus a bunch of other info. (18 months ago I would never have imaging I would be able to write this comment much less understand it!)
So much of what Ralph said went way over my head but his presentation was awesome. He has such a clarity of thought and a mind-boggling knowledge of such a complicated area of geology. I'll take this as a challenge to keep learning so that hopefully one day I can keep up with a conversation such as this!
There is an updated version of Ralph's map at the Methow Valley Interpretive Center, that extends farther east into the Okanogan. Finding the "terra incognita" that he references referring to the whereabouts of the Ross Lake Fault is a hint for researchers to direct more searches in the Alta Lake and Pateros areas for bedrock that can tell the story of the collision between the Insular terrane and Okanogan rocks. The difference between 90 MA Chelan rocks and 120-110 MA Okanogan rocks is the story of that collision that must have preceded the northward movement of the merged terrane Nick calls "the whale". Good outcrops occur in Alta Coulee.
Thank goodness for people like Dr. Haugerud for decoding the rock types which took decades to find out about them, by many other geologists , amid what seems to be a mismash mess with millions of years taken in the creation of them. Of course the North Cascades have a story but you need perspective of where it all originated from and that long map of the West Coast way back in time shows us a little of that. Great interview Nick!
Bought Ralph's book 'Geology of the North Cascades' at the NCNP gift shop a few years ago (then promptly forgot about it), but fortunate to have it right here beside me -- it is literally PACKED with detailed hand-drawn diagrams and lucid geological descriptions. Includes some color photos, a 1":10mi scale 1-page color plate of the USGS map Nick & Ralph are looking at in the video, an 8-page 1":3mi scale 'Points of Geologic Interest' topo map of the same area, a Geology Glossary, extensive 'Recommended Readings' and a thorough Index. Very well done!
Would love to see a 9X physical map like that with higher fidelity! It’s crazy to think one day AI like software might be able to take all those observations and speculate how each of those pieces and parts moved simultaneously in a 3D model over time to give the jigsaw of pieces we have today!
Another outstanding interview. I suspect there will be numerous Geologists who will have watched, and will be evaluating the information to piece together the ever expanding geologic puzzle. Nick is essentially the host of an ongoing forum accelerating the science. Some of the ideas which have been presented in a relatively short period of time may have otherwise taken years for the various participants to review. On top of that there are so many of us watching who are learning faster than we would have otherwise.
It's like Cliff Notes for N. Cascade geology on steroids. Nick asked the right questions, Ralph had the answers, and he explained why succinctly. It couldn't have been better. I actually feel I see the big picture that has eluded me since I first looked at a geologic map of N. Cascades 20 yrs ago.
Thank you Nick and Ralph! I love that you had rock samples lined up on the map where they came from. What a great concept and made it much more interesting.
Yesterday was beautiful driving through Wenatchee up to Brewster for a truck load of apples...the air had seemed to clear out. By the time I woke up this morning and left George, Washington, it was already getting smokey again. Thought I passed some basalt dikes like was described in Liberty, Washington.
Wonderful you are interviewing all these very knowledgeable people and documenting their extensive knowledge. Too bad they are getting redirected to other things stopping their progress. Just you asking these questions stimulates these guys to talk to each other and maybe complete some work with young geologists and perhaps write more articles and books. Really ashamed if their knowledge is lost before it is passed on. Such a gift
Wow! Looking at the map and hearing the commentary, the Northwest really is a bit of a freak show. I have no idea how you guys are able to try and piece it all together. I sometimes wonder if parts of Australia have anything similar to this and if anyone has done any research on it. You live in a particularly fascinating (geologically speaking) part of the world Nick. While it is a world apart from the east coast of Queensland, Australia, I still find it terribly interesting, if not difficult to wrap my head around what has occurred in your "backyard" over the last hundred million years or so. Thanks for the great content and I look forward to the next video mate. 😉👍
Have watched a lot of the thumper truck videos from Australia TH-cam and the related geology videos... gold inspired a lot of interest in the geology there.
I’ll bet the view is gorgeous when there is no smoke. Thank you for all the visits and trips in the field this summer. Those North Cascades! Though, thank😮 you Ralph for adding your expertise helping understand the lowlands and serious earthquake data. You never know what exciting tasks are just down the road. Nick and you exemplify it.
Yes the view great from the area Ralph lives in. It looks across the Columbia to E Wenatchee and Badger mt above. However the view from the E Wenatchee side over to Wenatchee has much more excitement to it. You see the Horse Lake road up into the Wenatchee mts. You see number 22 canyon and Castle Rock. Then on south to number 1 canyon with the big highlight of saddle rocks. The saddle rocks complex forms the shape of an old Spanish saddle over watching the town of Wenatchee. Then south and moving closer to the Columbia are Wenatchee Heights. Behind the Heights is view of Mission Ridge ski area. From the ski area north all along what I detailed above is the Ridgeline of the Wenatchee mts. On the other side of those mts is the main part of the huge and more open Kittitas valley. In that valley is Ellensburg, CWU, Nick Zentner and more beautiful but different views.
Wow! Here I was watching Chinese Kung Fu fantasy videos and something better comes along! Thanks, Nick and Ralph for such a yummy technical geology show. I will have to watch it a few more times to get my tired brain around all the goodies here. Hope the fires are out soon but glad for your plan B!
The Klamaths in NorCal have Exotic Terranes, and similar situations, metamorphic in some areas, sedimentary with fossils in others, and melanges as well.
10pm😄 I was going to bed, sure’s he11 (sorry Patrick) not now. I’ll add my questions as I listen. 5:35 Is the Sulfur Mtn. clinopyroxene crystaled plutonic rock sample metagranitic or perhaps metadioritic? Seems to me that the clynopyroxene would indicate remelting of granite/diorite, subsequent acquisition of some mantle rock and slow cooling before being exhumed/uplifted. @10:00, notice the NW orientation of the blocks, very telling that they were installed by a single NW oriented oceanic plate system much like (but not) the Pacific plate. We also know they weren’t rotated like the Oregon Terranes because of the BC Terrane complex “backstop.” The Sierra block and adjacent California Terrane’s NW orientation begs the question of how could the ESE moving Farallon plate be the conveying source of any of the Cretaceous Terranes? It’s the wrong direction; therefore, there must’ve been another North-NW oriented plate between the Farallon and NA, accommodated by an oceanic subduction zone. @23:07 Some interpretations can go awry if assumptions are made incorrectly, “stout-shelled” clams exist in the intertidal zones at the shores of bays and inlets, not the aggressive surf. Thin-shelled clams, such as razor clams dominate the surf zones. This is an important distinction if it’s being used to describe a paleo setting. @40:00 With the Atlantic MOR, how can anyone not be a “mobilist”? 47:24 That was an abrupt end right at the end of a point with no rebuttal or response, is there a part II?
Love your background commentary data | insight. Your acct name is popping up on my radar quite often , I thank-you ! Collaborative materials that you are providing are going into the data bank & plotted on my master map when possible.
Ralph was real enlightening, but as a novice I had to look up some of his terms. The NW I always understood, that it was complicated, but it's a mess! To have lived during it would have been more than a challenge.
What seems to make this so complex is one not only needs to restore the faults, but reverse the metamorphacitsm too which is one step too far for my brain to follow the conversation. I am excited to hear Nick tell a story that does this for a neophyte to geology.
Nick, is all of the blocks that are separated by faults exotic terrains? I have always wondered if all of the faults in Central and Eastern Washington are the boarders between different terrains
Regarding the final words of the conversation, why would you need to find evidence of offset in Mexico if the translation of the Baja BC terranes was along a transform fault resulting from the collision of two continents -- i.e. North America and Wrangelia?
And, if you want to view a .PDF, you can go here: pubs.usgs.gov/sim/2940/ Sheet 1 contains the Map Sheet 2 contains the backside with a lot of useful data

Ralph is just brilliant, soft spoken but a genius in geology
Data rich video - many thanks Ralph and Nick.
Great guy Nick! Ralph has a real broadcaster's voice! Do a podcast too, Ralph! Thanks, Ralph!
Fun and informative video. Geology maps are works of art and labors of love. Thanks.

I could listen to Ralph Haugerud all day. He is a treasure. I always learn so much from him. Thanks so much for this video!
Seeing Mappy McMap was like seeing an old friend.
I never thought i would be grateful for too
much smoke but if this is the result then I am.
Great video Nick!
Many thanks to you and Ralph.
It was so cool to watch the two of you bounce of items and discuss different ideas of how this area is different from another. Thank you!!!
There is a feeling early in one’s schooling that “everything has been discovered, and there is nothing left to do.” When we listen to programs like this we get the barest glimpse of how much there is left to discover. I guess one thing that could be said to new students is “This stuff is ALL waiting out there for YOU to discover, your mission in college is to acquire and develop the knowledge and tools to enable you to go out to the field and start filling in the blank parts of the map., and there are a LOT of blank spots on the map. It truly is the “Wild West out there!”
I really liked the use of rock samples to show their relationship to various geological features. Thanks Ralph and Nick !
In the last couple of days, I accompanied my friend with his Jeep from Cashmere in the Chumstick, over Entiat Ridge, over the Chelan Mountains, down to Lake Chelan, around its southern tip, then back up Cooper Ridge on the east side of the lake, down into the Methow River valley and Carlton, over into the Methow orthogneiss, then all the way back across Hwy 20, across the RLFZ and on down across the Straight Creek, and back home this evening, to find this waiting for me. Mind blown! Great episode and yet another set-up for Baja-BC!
I once stopped in Cashmere and let my dogs poop in the park! (Don't worry, I picked it up and put it in the drinking fountain.)
Really fun to listen to.

First UW beats MSU, now a new video with Ralph?! What did we do to deserve this? Thank you, Nick!
It cut off suddenly at the end. I hope that means there's a part two! Really enjoyed this one thx

I'm going to buy his book
I wish Nick would write one too
Just ordered one, good tip!!
Cheers Nick, you are a supreme educator 👍
Nick Zentner Rocks thanks for sharing this as all you did for us during lockdown a big hug from Spain

Holy Cow. Some great insights into these blocks, from a fellow who's been thinking about them for a long time. This one was a lot of fun!
Wow, first thoughts... need to watch again. And again. And again. Or maybe I will just wait until you explain(?) Fascinating. Thank you
Love this video, I’ve always been mad about maps! I’m in heaven!
nice job ALL thank you stay safe
Well, not going to sleep before 11PM now. 😃
It looks like you have videos for years to come Nick!

I've found fossil clam shell on a ridge just south of Slate peak. Hozameen! Maybe!?
Great discussion and gorgeous map!
Now i understand why is so difficult the North of Cascades...many mysteries 🤯

GNEISS PRESENTATION. GEOLOGY 901+ FOR ME BUT INTERESTING TO SAY THE LEAST. YOU NEED TO EXPLORE RALPH'S NOGGIN MORE IN THE FUTURE.
Awesomeness!
@ 35:45 ...which is at the edge of our map ... and we need someone to do that work.

Just thought of more on my last comment. You are the rock plopped in the pond😊.
i heard a large set of storms is heading down the coast from Alaska this week should put down some fires if the lightning doesn't start more...
Regarding the final words of the conversation, why would you need to find evidence of offset in Mexico if the translation of the Baja BC terranes was along a transform fault resulting from the collision of two continents -- i.e. North America and Wrangelia?
My goodness, this came to an abrupt stop. Baja-BC is such a big hook and you stopped right on the edge.
Oh my goodness!!!!
Where can I get that shirt????
That map is freaking awesome are those available for purchase?
I want to help make the maps he dreams of
