There was me, here 10 minutes from the White Cliffs of Dover in the UK, pining for geology that you have in Washington state. I've been in awe of the channeled scablands, dry falls streamlined islands & plumge pools cut out of sheer bedrock. BUT!!!! I just watched a video on how the UK became an island. It seems that I'm just a few miles from all these features! The ice sheets on one side and the chalk ridge that joined us to Europe on the other collected the water from the Rhine et al plus the meltwater as we entered an interglacial, formed a huge lake at the southern end of the North Sea held back by the chalk. I know that you all see where this is going! Add in a little earthquake (I've experienced these myself in Folkestone) and the chalk gave way... Preserved at the bottom of the English Channel are all the features yhat you guys have above ground. A line of dry falls (that if the sea wasn't there i could view by looking down into them from the White Cliffs between Folkestone & Dover) leading to 150 metre deep plunge pools, channeled scablands, streamlined islands ect. It's a spitting image of everything you've taught me about Nick! Watching the lecture I followed perfectly and had the I benefit of having seen all these features in your videos. I'll edit in the lecture in a bit as I'm on my 'phone but I had to cone and thank you for the grounding in your megafloods do that I can not only understand my own, but "feel" them too! Thanks mate! If we ever meet, the first round's on me! 🍻 It's called "Megaflood: How Britain became an Island" on the Imperial College London's KZbin channel. Also on the same channel "Britain's Lost Landbridge to Europe" Talk about deja vu!

As a member of the Seattle Glider Council soaring club based in Ephrata every summer, I spent over 25 years and many, many hundreds of hours flying my sailplane all over the Columbia Basin looking down at the beautiful terrain discussed in this lecture and others. Wow, what a treat to now get to understand a little bit of what I was looking at all that time! I often noticed that the land north of Withrow past Mansfield and on up to the Columbia featured those big boulders and areas that looked scraped and gouged. Your explanation crystalizes what my eyes were seeing from a few thousand feet up! Very cool. Thanks for another fascinating field trip!

This was super fun for us to watch, because we live on Bald Ridge. The old-timers around here called the fields on the edge of the ridge "The Breaks", because it is the line where the vast wheatland ends, giving way to the forest which marches north into Canada. Our house is less than 1/4 mile from the edge of the forest. We have the best of both worlds - open farmland with long territorial views, and also the nearby forest and the amazing pre-historic view to the north across the river... I've often pondered the geology of this area, it does seem so unique.

You should also take a drive down highway 291 that goes along the spokane River. Keep your eye on the south and west slopes and you'll see massive amounts of all different types of rock types. When you approach Suncrest, there's a hill called big sand you'll have to drive up. There's a pull off area there. Go down to where the barrier is and climb up. It's just a huge conveyor belt of every different kind of rock imaginable.

As soon as you started driving up the moraine the environment shifted from the wheat to sagebrush. From watching "Crime Pays" I know that's a pretty strong indicator the geology shifted as well. And then once you got to the haystacks, it was just all flowers and grass but no sagebrush. I don't know what it means but it was interesting to me!

Ever since the Bretz 1930 paper from last week I am looking around and trying to see the Wenatchee area through different eyes - Bretz said moraine overprinting a slide here in Malaga and moraine in East Wenatchee, yet right above East Wenatchee there are the deep loess dry land wheat fields of Badger mountain and the Waterville plateau. Hmmmm........ Things are getting more complicated rather than clearer, LOL. Given the sheer expanse of time for things to be altered over and over again by advancing and retreating ice sheets I think a lot more careful field work might be the only thing to clarify things here in the Wenatchee Valley. I think there is more to learn before it is "settled". Bretz was certainly an experienced field geologist specializing in glacial features, so I think his evaluation of the area has to be given credence or at least a second look. Thank you as always for taking us on these field trips and letting us see the features through your eyes, and giving us new things to ponder!

That question from the beginning... Considering I am from Connecticut, I don't have the most detailed mental image of Washington (the closest I have ever even been to Washington is Illinois), my answer was pretty close to that line on the map, though I was thinking a little further south (and with way less detail of course). Being from where I am, that basic question about how far the ice advanced, immediately and always makes me look east in my mind. Directly at Cape Cod. Which is one of the reasons I love Nick's videos. They are all focused on the other side of the nation. It is not that I would ignore the west otherwise, it is simply that stuff that is local or I can drive to in a couple of hours or have been to previously are a bit easier to learn about since I know the basics of the area already. I imagine his videos would be interesting regardless of where he was describing though.

Professor, I'm going to reinterpret your question: How much damage did the ice sheets do during the Weichselian glaciation? Well, my country was nearly scraped clean. We have so little of the sedimentary rocks remaining here in Sweden. What we have are pockets of old uplifted limestone (Öland and Gotland) and sandstone here and there (Gävle, Ekerö, Scania, southwest of Gotland), together with ancient wackes in various states of metamorphism. The rest is crystalline, igneous stuff and some real old shales in the south west. I'm told they have found dinosaur remains in the extreme south of Sweden, which is Scania, so I guess that's a thing. Of course, the mountains ("Fjällen") that were erected during the Caledonian orogeny brought up all sorts of rocks to the surface and not all of that was wiped out. Some of that stuff even made its way south as glacial erratics.

Nick I really enjoy your video talks , there is so much to learn and you do a great job feeding us the information. I was wondering if you might consider a trip to BC and to the Trail area of BC , north of Spokane and where the Columbia enters Washington. There is some wonderful , I call them cut bank moraines and aparently very nearly the oldest rock in the world ,which crosses the Columbia as a dyke. The Univercity of Alberta as in years past held classes there . If there where Ice ages periods which did not cross the border it might be something to look into. I believe there where more ice ages than we currently think. I have ice age eggs ( boulders the size of VW Beatles ) poking up all over. The Beaver Valley is actually part of a hanging valley with waterfall. Maybe you could have a look see sometime.

Thanks for another very fine video, Nick! I have to wonder if LIDAR imagery would show subtle elevation changes sufficient to define Bretz's horseshoe elevated area.

Still working on the first cup of coffee this morning, so maybe I'm not thinking clearly...
