The algorithm sent me here because I watch Nick Zentner

Thank you Jerome. Great presentation! I have very much enjoyed watching you on Nick's channel over the past few years. Congratulations on the new paper with Joel. Subvert the dominant paradigm!

What to me is most gratifying is that Joel and Jerome's paper explained months and months of onsite observation and mapping and data collection into a succinct, FOUR-page publication that explains not only the genesis of Moses Coulee but also a source of megaflooding that Bretz saw but few others did. I see it as solid theory personally. The only enigma left in this area is teasing out the evidence for Spokane being covered by a glacial advance that is older than the Wisconsin. _That_ will be difficult, inasmuch as the later ice advances plus the Missoula floods have likely wiped out the best evidence for a Spokane ice lobe. Bretz plainly saw it, but it's difficult for the rest of us to see what he saw.

Definitely helps if you watched Nick’s Ice Age Floods A-Z , which Jerome was on a few times

Great lecture ! Thank you Jerome !

Thank you for presenting this Jerome. Very interesting! I now wonder if there were other subglacial outburst floods in the upper Midwest and Ontario that have been misidentified.

excellent

Very interesting to a curious and intrigued non-geologist. I stumbled across the Ice Age Floods story several years ago, and finally visited Moses Coulee in 2022. I will return this summer with lots more to think about and look at.

I understand there has been some struggle over time getting your work published/recognized and I am so grateful this collaboration finally allowed that to happen. Sadly, not unlike Bretz on some level. Academia and academic egos can be a challenge to understand systemically, sometimes. Clearly, actual geography doesn't acknowledge contemporary political boundaries (nor should it) and this kind of collaborating is exciting. Thank you for your work and this presentation!

Very good Jerome. You have come up with an additional story rather than a replacement story.

Great talk Jerome! It's given me a lot to think about. I'm going to be around Moses Coulee for 2 weeks or so in Sept. I tried to follow your talk on Google Maps, so I have found more places to explore. I'd love to talk to you and Joel someday about it. Greg in east TN 😀

Thank you Jerome, this was awesome!!!

Just waiting patiently for the reverse flow glaciated Elwha story to rear it's beautiful little head.

I like Rainy Pass. Connects the Lower Fraser to Stehekin and Chelan. Thank you Jerome, Skye, and Joel for your inspiration.

Thanks for sharing. Mega floods are common from large ice sheets. Cordilleran Ice Sheet had to drain south.

Thanks Jerome!

Dope talk, love that you destroyed so many skeptics' talking points!

Thank You. Somebody at Home, talking! Stop it!

Plenty of Ice Rafted Erractics here near Enderby BC Canada, espeacially up Kingfisher and Sleepy Hollow Foerst roads !

Are there ice rafted erratics that have been dated to the “Missoula floods” timeframe present in Moses Coulee?

Are the landforms the result of the max velocity? Have some been modified by later slower events? Does max flow and max velocity happen at the same time? It seems the wavefront would be slowed by the initial resistance of the prior landforms and that the velocity maximum would happen later. Are areas where deposition occurs the only ones where we can calculate the flood velocities? Is there any indication of the time sequence of a particular flood event? Enough...?

Heritic!

I must take exception to your diagram depicting scabland creation in the proglacial setting and consequently in your subglacial erosion theory. Your diagram shows only water doing the erosive work rather than the slurry of boulders, gravel, sand and silt that would be the actual carving agents. When you then translate to subglacial flow, how do you get the masses of grinding rock necessary to carve such channels?

The problem with the outbursts theory from damed glacial lakes is that it does not account or discuss whether ice is capable of holding the immense pressure created by the huge amounts of water that caused these ancients floods before cracking and giving away. Are the recent icelandic examples valid as analogies when they are all thousands of times smaller than what happened in north america? The extraploation imagining them 3 or 4 orders of magnitude bigger without considering whether ice is capable of holding the pressure from the enormous quantity of water is very dubious. Especially when we see that all of those outbursts that happen today are in fact lightyears from being just a tiny bit of what happened there really. It would be more plausible to imagine that something else was at play back then and maybe melted a lot of ice rapidly at once.

Good work. Seems to make sense. You can basically see it from google earth. So why isn’t this part of the standard story? Is it because of america centrism? Or other?

I think your theory is obvious. The Canadian gutters are scoured almost to southern Alaska.
