I just discovered these. I've had a casual interest in geology but you've really piqued my curiosity and have made me want to dig deeper, no pun intended. I believe it's your great teaching style. I discovered you through your lecture on flood basalts. I have no idea how or why I found that particular one but I was transfixed for the entire lecture.
Better late than never. Here from KalamazoO with an eye bent towards the ground looking for Petoskey stones and listening to ramblings from Washington. State, that is.
your audio and visuals are almost always good when you ask. Also, external noises that bother you do not come through on our receiving end so you can pretty much ignore whatever is going on around you.
Watching this in replay and had a thought regarding the glacial lakes sediments ( aka Carrot Cake ) . As you described the layerings of Varves vs. Rhytymites and the layers of light/dark/light... in the Varves themselves, which indicate the number of years for the development of that particular layer ( Varve ). Does this potentially describe an ice sheet ( or rather a glacial lobe ) that advances ( grows and moves in a southward direction ) then retreats then advances again ? Potentially creating the opportunity for the Varve layer it’s time for development through sedimentation. If this is a sound thought process, could a detailed study show if there was a growth/thaw/growth pattern of the glacial lobes allowing the glacial lakes to repeatedly fill then drain ? And by doing so create the layers of sedimentation that is at the bottom of these ancient glacial lakes ?
1:11:50 The Ash from St Helen's is striking of course. Taking a wider view there has been considerable erosion or removal of material to expose it, and all in less than 16,000 years. Is there an explanation for this?
You would think that after 10,000 years, or whatever, those areas swept out of loess by the Ice Age floods would have acquired enough wind dust to grow vegetation.
Is there any loess land that hasn't been cleared of it's natural flora and ploughed? Looks like an entire ecosystem has been destroyed, and the soil must still be being lost without the deep rooted native plants to retain it. Some years ago, the UN FAO 'Year of the Soil' estimated the world only had enough soil left for 60 harvests. Looks like Washington must have a large portion of it. Hope you're looking after it!
to the group of folks "playing along at home" in the comments.. probably a little dangerous picking "Missoula" as your word. Akin to playing Slug-Bug but with Honda Accords instead.
The outstanding question for me is, apart from deposits laid down in slack water.....since loess is windblown and subject to weathering and rain, why hasn't it all washed out to the sea? What's fixing it on land? After all, the Loess Plateau of China still has thicknesses of more than∼300 metres, that's 935 feet, 328 yards, nearly 3 soccer pitches. You say there's no organic to fix it. We know from dunes how sand is fixed. But sand is heavier than loess. I can only assume it becomes compacted; otherwise it's going to blow away like the Dust Bowl of the 30s, ending up in the sea.
@@tysonsmudfossiladventures3468 How about you 1st prove it's not made of basalt? Then lets move onto the basalt pillars that you all claim are trees... 😆 Then show me the science behind Australia being a heart. Organics do not form rocks btw...

Sir, I absolutely love listening to your lectures. My father was a teacher and you remind me of him. I just discovered your livestreams. Thank you.

Excellent new cozy fort! Thanks so much for these wonderful lessons and interaction!
You may not be able to taste the loess, but I think you could taste the love. Thanks for another great lesson.
Hello from South Carolina
Thanks Nick
Greetings from Germany 🖖🏼
*in breaking news, carrot cake sells out worldwide due to hungry Zentnerds*
German chocolate cakes too! 😋
Now I want to make a German Chocolate cake with a Carrot cake on top. Maybe call it a Lake Lewis cake.
You'd have to sneak in an additional layer for Ringold Formation. But the Lewis Cake sounds delicious.
That's a remarkably tough cake considering his wife had stood on it before it was shown in the video!

Wow, that is fast turnaround. You just finished and the replay came up right away.
You should do a show about mt mazama
Just doin a lil recap before the new series 😊
Eta- i watched this live, but im still afraid youre going to drop that gorgeous cake! 😱
Seems like each slackwater layer maybe gets shallower because each time there's less loess left to get washed down.
God that cake looks good!!!!
Watching the recorded lecture. Why no chat playback? I love reading the comments.
Dive right in!
That is an epic cake!

Wondering your thoughts on Randall Carlson? I think he's got some great ideas
Don't mind the long lectures, as long as your better half is OK with it LOL
The loose loess in Lewis.

I think chocolate milk describes a flood perfectly. But add trees and rocks.....cars and trucks.

Add a little alum and the soil will precipitate very quickly.
Could Kitchen Flour be from Ghost Volcanoes ground away by glaciers, which are then carried by wind to East WA & OR?
I'm telling you, Evelyn is 62 years old.
At 42:28....Whoa my Fav Cake.
Whole wheat flour is brown.
Should change it from Lk Lewis to Lk Loess
Here's the link for the Brian Atwarer article about Glacial Lake Deposits:

Someone put some fondant on the cake! :-)
We all could use a nice milk break.

Loesd is weird , my guess is it's flat an disk like ,to fly and pressed flat by graviety ...like a piece crust ..is tougher than flour.
