Okanagan Eskers w/Jerome Lesemann - Nick From The Field #53

[@stevesmith997]

Love how you and Prof Jerome are making the connections between BC and Washington geology.

[@mikekirk1513]

I just want to say that I'm glad you made it up to B.C. to have a look around.

[@Cliffwalkerrockhounding]

You are inching closer! I am lagging behind on consuming the content, so, perhaps you are already in the vicinity! Haha. It is so WONDERFUL to see you in my area, answering questions I had not yet formed. Another hour to the North west... the vulcanism needs to be dated. Volcanos, fossils and a petrified forest will answer many questions. Thank you again for the knowledge.

[@vrichenstein]

Just a hint of the awesomeness of ice age processes demonstrated in today’s field trip. Thank you .

[@vinmansbakery]

I’ve been looking on Google Earth to see where Ice Age floodwaters maybe came from up north in Canada. This video hits the spot! Can’t wait to hear Nic talk about it, too.

[@d.t.4523]

Were you looking for some inspiration, to decide on a new pastry? Thank you! 🙂 👍

[@DanEspresso]

Just northwest of Prince George looks to be the epicenter of all the drumlins.

[@peacenow4456]

MANY Thanks for all you do for Nick, his students and the community! I always get happy for folks when you and your bake goods show up. I love pastries!! Yours look so yummy! Cute idea to name new baked goods after Nick's shared landmarks. I often wish you could mail pastries to San Juan Islands!! Hugs...!!!

[@jamiewhittla2293]

I moved to this area this year, and just recently visited Layer Cake Mountain. It's great to learn more about the geology I'm seeing. Thank you so much for the informative videos.

[@FlyinRyan231]

Check out the Abeerdeen Basalt Columns near Lumby!

[@1234j]

He's gooood. Fascinating. Thank you to everyone for all this information. Cheers from Jane in England.

[@bctrails7206]

The basalt chasms/slot canyons along the Tranquille river watershed valley in Lac Du Bois grasslands are amazing! The current river course flows directly through the basalts even though there are glacial sediments consisting of consolidated gravels and ancient lake or sea bottom silts overlaying them that were seemingly in the existing rivers path as it cut through the basalts.They can be veiwed via one heck of a leg burning hike down into the Tranquille river valley from just before the 9km mark on Tranquille-Criss creek rd at the pullout parking area/trail head.Great vid!

[@markbrideau588]

Yet another video!!! Thanks for the capture.

[@Columbiastargazer]

For location details, you're just south of "Black Mountain", near highway 33 (the road just below you), between Rutland and the Joe Rich area

[@pj1378]

Thanks, I was trying to place the location, but I don't know that part of Kelowna well.

[@rickmarosi-yz9wt-s5b]

.5 km West of Pymon Rd. See the parking turn out.

[@brianlhughes]

I grew up in Tonasket. We found a line of clam or mussel shells in the gravel sediment layer in the hillsides near town. The layer wasn't deep, only an inch or so. Mussels breed using fish to carry their young. I'd wager the ice must have retreated north of Tonasket, probably even north of Osoyoos, enough to provide an ecosystem for the clams for that short while. Fish must have brought the mussels north from the Columbia.

[@billstronk4321]

As always - absolutely fascinating, and superbly explained. Thank you both so much for sharing your knowledge of and interest in geology and geologic history!

[@snarky_user]

Many years ago, there was a Scottish geology student researching glacial deposits at University of South Dakota. He was looking at aerial photography and amazed at how linear and regular the eskers were -until he was told they were abandoned railroad lines.

[@churlburt8485]

POWERFUL MESSAGE Thank you Nick

[@sgtpepperz25]

Thanks for taking the time to make these!

[@DAYBROK3]

as mr nick is walking along all I keep saying is "Mr nick slow down and point that camera at the ground I want to see the rocks" 😁

[@p.d.nickthielen6600]

Nick again thanks, I wonder if there are areas like those near where you grew up in Wisconsin in this area. I.E. Driftless area type structures, large continental glacial structures that created huge lakes like we find here in Minnesota, other areas where ice may have cut off natural water flow and then ice dam failures like you see in western Washington.

[@deborahferguson1163]

Another great geology lecture!!! Thank you!!

[@chaeclark8118]

i saw Chasm in person this weekend. absolutely aw inspiring. i had to search youtube for more information, thanks for posting this!

[@steel1182]

Should have known as soon as I leave you post something neat thank god for replay..thanks nick!

[@northwoods3d]

this one was not live, or even a premiere, just a bog standard upload, so it is basically a "replay" for everyone the video itself was recorded on Oct 2..

[@mardinecampbell2870]

Wow. More Canadian trips in my future. Thanks

[@sidbemus4625]

At 12:12....Wheel of Fortune " response". Time to renew my passport.Thank professor Lesemann.Thank you Nick.

[@JenniferLupine]

Great field trip!

[@charliebartholomew1564]

Thanks again Nick, more geology info v/cool here in MN

[@TheDevice9]

Somehow I missed the part where you tell me what an Esker is.

[@bagoquarks]

Yes, me too. I paused and looked it up in Wikipedia.

[@d.t.4523]

It's an underwater deposit of sand and rocks that washed out from under the glacier. It settled to the bottom underwater, not at or above the surface.

[@pollyb.4648]

@@d.t.4523 In my geology classes we called rock formations left by glaciers moraines. Maybe it's different because eschers are deposited into water and moraines onto land?

[@apextroll]

@@pollyb.4648 Maybe eskers are from moving water under the ice sheet whereas moraines are deposits from the melting ice sheets itself.

[@michaelhusar3668]

Esker is formed by glaciers in Canada, Moraine is formed by glaciers in the USA. 🤣

[@canadianentropy]

Is that site above Highway 33? Near the Okanagan Adventure Park...

[@BlGGESTBROTHER]

Thanks Ned!

[@ArtDeGuerra]

Awesome videos.

[@robrepin8105]

Is it safe to assume that an ice age esker "ridge", might be perfectly marking the path of the much older course of an ancient river "channel"?

[@bruceinoz8002]

We don't get scenery like this very often in Australia. Our cousins in Kiwi-land do. At 12:57, are those horizontal striations on the hill in the background, glacial?

[@lynnmitzy1643]

Thank you

[@waltdavis9543]

Wow! Glad you went to BC and gave us a window into Prof Jerome's class. Eskers are made up of material that has been worked and reworked my many ice advances and retreats over the last 2.7 my.

[@MrGordy2630]

My home town since the early 70s The water levels of would have been about another 150 meters above that point where you were standing,stretching north towards the thompson valley. The floating bridge design was first used in 1957 and was just recently replaced..much needed...that design was used due to the lack of bedrock on east side of the lake ,the depth of the lake in that area is about 45 to 60 meters With some parts getting to 85 to 95 m. Down in the canyon below layer cake mountain you can still find deposits..? Od what apears to be a thin layer of volcanic glass..ish type of material..not sure what it is.. Great vid ..looking forward to more of your vids on the area

[@aaronsterlind6334]

I love your videos, I live in the Kootenay Boundary country of BC, Grand Forks actually, I sure wish you could come here.

[@2ddw]

A couple of comments: 1. There is just not enough acknowledgement, talking, presentations on the geologic connection between northern WA and BC. It's not as if geology ends at the 49th parallel. 2. The interior BC valleys like the Okanagan, like the Thompson, etc appear to all have held glaciers as the Cordilleran ice sheet melted, yet these valleys don't have the classic U-shape. Did these valleys hold glaciers when the ice-sheet was growing? 3. I'd love to hear Nick give a lecture/lecture series/class on BC/Northern WA geology - I haven't come across anything that isn't so watered down as to be useless. 4. The field trip is just fascinating. 5. How do you tell the difference between an esker and moraine?

[@trashjournalistjourney6104]

Prof Zinter will there be another Pop up soon?

[@jamespmurray4059]

You should start your own channel. It would be good for BC.

[@jeromelesemann1855]

Thinking about it...

@@jeromelesemann1855 Thank you. Keep us posted. I'll subscribe in advance. 👍

@@jeromelesemann1855 Already subscribed incase you decide to in the future. Unraveling the mysteries hidden in plain sight around us in a clear understandable way is one of the reasons many of us are following Nick. Even if its just more collaboration, it seems like people would be interested. You seem to have many of the same tallents and enthusiasm to convey the story in a entertaining and interesting way that we can visualize.

[@PrincessTS01]

Do you think BC a better Disneyland for geologists, than Washington? Or can we consider BC a Six Flags type of place? Me being local to the real Disneyland and the local six flags being so hard to get to, i feel its a fair comparison.

[@BlGGESTBROTHER]

The problem with BC is that it's so lush much of the geology is hidden under the overgrowth. Eastern Washington is great because it's so arid that you can easily observe the fingerprint left by the Ice Age Floods.

[@bagoquarks]

*A BEWHISKERED* busker climbed the esker and began fisking on the risks of using a whisk. Did I mention he was from Saskatoon, Saskatchewan?

[@johnnash5118]

This is a great example (Wallowa Lake Moraine is another) of what eeeactually played an important part of impounding “Glacial” Lake Missoula, but on a much greater scale there. You never hear about the Eskers and Moraine impounding the lake, brought down through the Purcell Ice Lobe. If the Pleistocene Hurwall glacier, a fraction the size of Purcell could have created a 700’ high moraine impounding Wallowa Lake, the Purcell Moraine must’ve been an order of magnitude larger, like @1,500’.

[@bagoquarks]

*ESKERS and DRUMLINS* - I am assuming that eskers and drumlins are both artifacts of continental ice sheets but are otherwise distinct phenomena, i.e. - drumlins are NOT micro-eskers.

[@d.t.4523]

Eskers would be the frosting on the German Chocolate cake. The drumlins are the swirls in the frosting. Work for you? 🙂

[@bagoquarks]

@@d.t.4523 I was thinking after reading wikipedia that eskers were hydraulically shaped (jets of melt water being squeezed by the mass of the ice sheet) and drumlins were "bulldozed" by rivers of solid ice that were diverting around hard points on a flat landscape. What I am not concluding is that drumlins are stranded bits of eskers. After watching Nick's YT uploads for over 3 years I still can't get my head around a mile-thick slab of ice covering 25% of North America for thousands of years.

[@d.t.4523]

@@bagoquarks The ice was 2 miles thick. Maybe that's why you can't imagine it a mile thick. The drumlins were formed by water currents at the bottom of the rivers and flood waters. The material they are made of is mostly the eskers that formed before the last big melt flooding.

[@ttmallard]

Another metric now used to order moraines chronologically in locales is by surface cores to gain cosmic ray erosional effect layer, exposure south of the glacial ice extent a basis my flash. The other is a strata of melted out rocks & debris form in a channel unique in micro life from surface sources of UV & GCRs. Thx, good video 🍺

[@tortland1]

About how deep is the sediment layer that Nick was walking on?

[@jamesparker6876]

Imagine the size of the Glacier as you look at the size of the Esker.

[@d.t.4523]

Easy... Canada with 2 miles of ice on top! 👍

[@jamesparker6876]

To: @@d.t.4523 Easy for you maybe. Two miles of ice is not easy for me to imagine.

[@d.t.4523]

@@jamesparker6876 Well, maybe looking at it as if it were an upside down ocean might help. Only it's frozen.

To: @@d.t.4523 Nope. Can't see it.

You really need to pay attention since Prof. Jerome speaks so much faster than you, Nick! Replayed the video at least twice and still can't catch the "... fans?" Please explain, if you could? Thanks a bunch!
