Nick has got to be the most incredible instructor in geology. As he has only the most incredible guests. This community he has helped bring together is just so informative. A huge thank you to all that help make this happen as well as to their families for the borrowed time.

As a Columbia Gorge resident (between the Mosier Syncline and Ortley Anticline) I found this episode of particular interest. Between your alphabet soup and now Jim’s rabbit stew to consume and digest I’m overwhelmed, happily. Thanks.

Wow, Now I am all caught up, and as you and Jim are talking, it all clicked... and as I am rewatching this, I said "I gotta go rewatch Ancient Rivers now!!!!" So before the Cascade range (3mil yrs+), is it possible the Columbia, the snack and the salmon all flowed straight our to Puget sound? then the uplift of Ranier, St. Helens, Adams and Mt Hood altered the flows of the various rivers so they came out at difference locations? I am amazed how well you keep on target, and don't get off on tangents... maybe thats why i teach 3rd grade!!!! "Squirrel!!!"

I read in an older Roadside Geology of Washington State that the Chehalis river, in it's wide valley, is the remnant of when the great ice sheets blocked the Juan de Fuca strait and the only outlet for all that drainage was Black Creek, via a low pass at the southern end of Hood Canal and into what is now the Chehalis valley. But that story is an old one.

You could always add the letters back to the alphabet that have been removed, to add more shows. The Ampersand (&), thorn (þ), eth (ð), wynn (ƿ), yogh (ȝ), ash (æ), and ethel (œ) were all valid letters at one time.... :P

I enjoy these very much. Iv'e been notrh of Astoria a bit, and looking at the land, iv'e wondered if the Columbia had been connected to Wilipaw bay in the past. And plant fossils in the Eagle creek unit? Nice! The work put in by the Zentnerds is awesome, and they have my admiration, it has given the series depth and a historic perspective.

Jim answered the main question that has been bothering me. If the Spokane flood did the work to dig out the coulee network and the reservoir was not Lake Missoula then where was the catchment location large enough to generate that amount of energy? I can see the Spokane glacier generating outwash but not giant floods. Thanks for another great program!!!

I was pleasantly surprised to hear that the blonde quartzite cobbles were not, with a few exceptions swept into other drainages, because I have found beautiful blonde quartzite cobbles quarried from the Molalla River quarry down to 50’ below the surface. This quarry is located in Canby, Or., 30 miles South of the present Columbia River channel. It’s where some geologic studies have shown a Miocene Columbia River had once flowed before the @16Ma CFBG inundation. Local landscaping companies selling loads of “river rock” are great sources to see what’s been washed down whatever river drainage it was quarried from, easy to find out. If I lived @the Puget Sound or especially the Fraser River Valley, I’d make a trip to one of these places and ask to snoop around to “sample” their products and look for blonde quartzite that sticks out like a sore thumb among igneous rocks.

Nick: I've been watching bits & pieces of your material since COVID hit. Good stuff. Regarding Bretz shifting gears away from Pacific Ocean incursion, a thought problem for your consideration. His study & research predated the understanding of the 3-500 year Cascadia earthquake cycle. Estimates of the land shift upwards as the NA Plate is released from the subducting Juan Defuca Plate are considerable reaching 15-20 feet if I recall correctly. A combination of slightly higher (pre-glaciation)'sea levels & much more extreme subduction binding pulling the western coastal edge of the NA Plate lower than current thought makes it quite easy for the Pacific ocean waters to spill eastward. Given that we're talking of time periods in the 100's of thousands of years (meaning many, many multiples of the 3-500 year boundary earthquakes) and presumably all as part of the creation of the Cascadia, the source of the water & geologic record that drove his initial hypothesis might indeed be correct. Just trying to apply understanding of the earthquake related materials to the matters at hand as they seem inextricably linked when you consider them. Your thoughts?

Really enjoyed your conversation! Getting stoked to go out in the field this summer to see these wonderful traces of the past! Just discovering this lecture series, want to go back and catch up! Particularly interested in Columbia Gorge and aftermath of the Ice Age. Maybe if you have topics that exceed your timeframe, maybe you could set up a discussion forum, and circle back if warranted. Hi from Newport, where the ancient Columbia apparently didn't quite reach!

During my exploration and drilling throughout Tri-cities, I’ve always found large cobbles and boulders atop coarse grain sand. I drilled at Kennewick’s WWTP and found gravels to 35-feet and then sand to 40-45. Below sand I found a greenish-blue gray soil. Did atterburgs testing on it to find it was slightly plastic and was a clayey silt. What I’m saying I guess though is that it seems I find more energetic alluvial deposits with large cobbles or sand atop silty sand or silt deposits.

So, when we are following clues for Ice Age Flood in Quartzite, we are looking for metaphoric quartzite Erratic rocks, not blonde quartzite gravels, right? 😉✨💛Thank you for Jim awesome talk and conversations with Nick!!😄💞💗I enjoyed and amazed with you all!!💫

Re: Why Richard Foster Flint was such a strident critic of J.H. Bretz According to Jim O'Conner, pg. 4 of his "Megafloods Paper" (your title), Flint "may have had an axe to grind", because Bretz sat on Flint's doctorate committee and voted to fail him. Of course, they were all professionals, but who knows...

I live in the hills of Hillsboro Oregon out in wine country surrounded by hundreds of acres of wineries I live on a lavender and Douglas fir Christmas tree farm next to a cemetery the rocks I find shouldn't be here. Lime stone river rocks bedrock quartz combinations that I've never seen before. I always wondered how this river rock got here along with the bedrock and lime stone

Possible someone knows a bit about the "Andasites In Columbia Valley at Goble" from the Bretz "To Determine in Summer of 1920" paper ? It's the second check mark annotation Nick made on the printed notes in this episode. The train went right through there according to the in period rought map I think? Is that information of that area available in some Bretz paper , or possibly covered elsewhere?

Since anyone reading this is probably a very nice person I expect I will receive no ridicule for what I must ask: please, please, please somebody tell me what does 5x freakin' 5 mean? I was thinking I would figure it out, or find out... but neither of those things have happened. So you can see my problem. Peace and love.

At 1:55:00, Nick goes into Chamberlin's observations. Chamberlin didn't have the time to figure out what he was looking at. CHAMBERLIN MISSED ON HIS OBSERVATIONS of the terraces he sees around Flathead Lake. In his mind, is it possible that Chamberlin felt he should have been the one to come up with the flood story in 1885? Bretz surpassed him and documented what Chamberlin had "obviously" missed. Rather than be gratuitous, he was jealous and chose to gaslight.
