This guy needs an award. He is simply the best geologist I've listened to on RU-vid, and I've listened to a lot of them. He's very good and explaining things.
I own the Granger Clay Pits that Nick and Dr. Lydia Stasch visited at about 53 minutes into the presentation. Dr. Stasch has dates for the zircons from my property, 10 million years old from the Salmon River.
btw that paper, Smith, Gerald R., Neil Morgan, & Eric Gustafson. 2000. “Fishes of the Mio-Pliocene Ringold Formation, Washington: Pliocene Capture of the Snake River by the Columbia River.” University of Michigan Papers on Paleontology No. 32. has a pdf available at www.researchgate.net/publication/30849423_Fishes_of_the_Mio-Pliocene_Ringold_Formation_Washington_Pliocene_Capture_of_the_Snake_River_by_the_Columbia_River And for fun, Idaho’s wine industry operates in the valley of that old paleo-Lake Idaho a 2006 article www.researchgate.net/publication/43280455_Geology_and_wine_11_Terroir_of_the_Western_Snake_River_Plain_Idaho_USA/link/5554bd2b08ae6943a871acee/download
Oh my goodness you guys have it all in Washington state. Faralon plate crashing in, ice age floods, the Cascades, super volcanoes. And most of it is so new, we have the Jurassic Coast (UK) but that's a bit dull. I've got to say it, you are one fine Teacher. Thank you for finding the time to put all these videos on line.
This is one of the lectures that first got me wanting to take a class from Nick. What a blessing that he has put together several classes and nearly 100 lectures in 2020 that we could listen to remotely and even participate in. Can’t thank you enough, Nick. Hope to hear many more in the new year. Happy Holidays.
I am watching this video from a couple years ago but enjoying the lecture thoroughly, Today happens to be my first boat ride east of Vernita Bridge. This Desert does not disappoint, It is absolutely breathtaking. Between the beautiful Columbia River sights that is loaded with numerous waterfowl including Pelicans, Blue Herons just to mention a couple. The White Bluffs are something to behold, A unexpected beauty in a world surrounded by Basalt.
I read the type locality paper on the Ringold Fm by RC Newcomb where he talks about the damming of the ancestral Columbia by the Horse Heaven Ridge Uplift that made Lake Ringold. I’m curious if that is still the accepted mechanism for lake formation and what the underlying tectonics of that uplift are. Hopefully Ms Staisch will address that topic in her research!
I'd love to see some correlation between the fish fossils associated with the Ringold formation and those found near Clarkia, Idaho...much further east than these maps suggest. Love these lectures!
How many fossils.are.buried in the ash flows? and.has anyone used an ultrasound device to map any mega fauna trapped fossils in the despoits? Thank you ms
Has there ever been any consideration that instead of the lava basalt pressing down on the earth in the region, it's the removal of the lava from under the earth that is displaced to the top of the earth? Like in Hawaii's last Eruption you had the crater drop in the caldera and flowing lava miles away from where it had come from?...
An alternative age and mechanism for Hells Canyon would be variable. The Snake cut a canyon through the older sedimentary layers before the Columbia River Flood Basalts (CRFB,) then was dammed, penetrated through, collapsed the permeable dam, and continued the erosion. Layer upon layer, and many damming, penetrations and collapsing processes to its current state. Oregon's McKenzie River is evidence of the process; the river disappears for miles under lava flows then reappears at Tamolitch falls like a leaky dam.
The "gap" you're looking for is in Nevada. The Basin and Range formation of central Nevada as a result of the crustal thinning due to it being stretched apart. 👍🏽😁
You have no pooka(?) shells? I did not think you were someone who categorized individuals, ha. And you needed a different brother in law, ha. Still these lectures make more sense every day.
maybe you could suggest to the gal that she should check sands along the secesh and south fork of the salmon rivers, then upstream and down from the confluence of the s.f. and main salmon
Invoking a hero GOAT o'mine, Dr. Robert Gary Litchford, RIP w his bride reunited...i ask...what satellites/sensors might one best find mantle heat plumes, reckon?
@1:02:15 If the zircons in the Ringold formation are 8 million years old and they are from Lake Idaho does that really indicate there was a connection between Lake Idaho and Lake Ringold at that time? Couldn't it be that those 8 million year old sediments from Lake Idaho were transported to Lake Ringold 3 mya when the Snake River opened the connection between both lakes? My guess is that this connection must have been pretty violent at times with a lot of erosion involved because both lakes don't exist anymore.
Why couldn't the pacific exotic terranes bumping up against old north america cause deep gaps?, the deepest at Hells Canyon. When the two land masses joined together, why do you assume they meet one flush to the other? You seem to be locked in to the erosion idea.
Great video, your content is top tier. It should be noted that the only reason for the 8,000 ft depth of hella canyon is the seven devils sit on the rim. It goes from 10,000 feet at the summit to the bottom around 2,000. Most of the canyon isn’t that deep. Still fascinating. Cheers from whitebird.
