    Most interesting. I was born in Baraboo became a fossil hunter in Westby, the BadAxe river, and can't wait to go check out what you have taught me. THANK YOU!

    I was just at van hise rock today and it's fascinating the plate on it from 1923 said "slow earth movement" altered the rock. They didnt know what eles to call it. All figured out before plate tectonics. They were simply brilliant

      Yep! They had no clue what formed mountains then. But they knew how to describe them and predict the structures. I plan on having a 100 year tribute next year too.

    Enjoyed this so much, thank you! Now I’m inspired to take some field trips into the area when I’m back home.

    You know what, after the hellish year I've had, watching your vids is very relaxing. As ever, noticing the patterns is one thing; explaining them is something else! Just one thing: watch the weight gain!

    Steven, my dumb phone keeps going out. That young boy I gave your channel to, with a bunch of interesting rocks, loves your channel. I don't know much about him, I deal with his Mom, but she's going through some with him, your video on science, geology as a profession, she mentioned. Oh, and beautiful area, I was born in Wisconsin, but left young. But I learned a lot from this! Main thing, never go for a walk with you! lol, I did enough of those climbs, looks identical, on archery shoots in East WA/ORE border. I did well, though, compound bows, 3D animals. Lol, in 1995/6, very few women at first. I always, for some reason, hit the standing bear, (forty yards or so) low, tween the legs. My husband and often 8 or more guys would all groan, together. Invariably, my husband said, 'yeah, she manages a Humane society! They neuter everything. I'd grin, they'd step back! Great video! As usual. I've been peeking, liking, but not commenting. Lucky, huh! Luv ya! 👍🏾👏💝☮️🐝

    Hi! I’ve been going into sleep deprived deep dives to try and debunk a creationist geology video featuring this feature. I would like to see your responses to them! They claim only a catastrophic event could have turned these beds vertical. They cite a global flood as the solution to this.

    I’m at the lower narrows right now, and I’ve just found what I believe to be a slate lens inside the quartzite. Have you heard about any slate within the Baraboo quartzite?

    • @stevenbaumann8692
      @stevenbaumann8692  3 роки тому +1

      Yes. It’s actually phyllite. It’s low grade metamorphic. We actually use some of it as examples of stress fields. No one has worked out in detail if they are more abundant in one area over another or if they are more common higher or lower in section. Other chrostratigraphic equivalents like the Souix have more. Plus there’s Precambrian mudstones above the quartzite.

    Cool spot! I've only ever found horizontal ripples, and not too many of those! Lol! I have a piece of feldspar (peristerite) that has what almost looks like waxy ripples on a couple surfaces, but they're obviously not ripples..

    ??these were formed before the glacier movements? about how deep to bedrock? 👍🏼 have you theories on glacial events? ✌🏼from SW Great Black Swamp,,Ohio/Indiana St.Line

    • @stevenbaumann8692
      @stevenbaumann8692  3 роки тому

      Hello! Thanks for stopping by!
      This is the bedrock. It’s just west of the furthest glaciers. That’s why it’s called the drift less area. We aren’t sure why the glaciers bypassed the area.
      I don’t study the Quaternary glaciers anymore. I study mostly the Precambrian rocks like the Baraboo quartzolite. The events that created the baraboo syncline predate the glaciers by well over a billion years. You need an orogeny (mountain building event) to fold rock like this. Ice isn’t powerful enough.

    I have a question... it's gonna sound dumb...
    What caused the deformation of these layers to bring them to a vertical position?
    My best guess after hearing how old the layers are (between 1.7 - 1.5 billion years) is the formation of Rhodium.
    I'm no Geologist, but I really enjoy learning about our planet's Deep Past:)

    • @stevenbaumann8692
      @stevenbaumann8692  3 роки тому

      There are no dumb questions. The syncline was formed in an orogenic (mountain building) event thru tectonic compression caused by continents colliding because of plate tectonics. Just like in the Rockies. Except the mountains are all but gone now. There’s a large number of eroded mountains from this point north.

      And I meant to say Rodinia not Rhodium :P (blasted auto-correct strikes again!)
      It fascinates me looking at those ripples and seeing where a river with no name once met an ancient sea... the only knowledge of which we have is those very ripples.

    At 7:57 you called it a lens, can you clarify for the uneducated but inquiring minds? All the results I’m finding are names for a specific type of magnifying glass.

    • @stevenbaumann8692
      @stevenbaumann8692  3 роки тому

      In stratigraphy most people are aware of “beds” or even “laminations”. But sedimentary units don’t continue forever. Some will be shaped like a lens. In cross section they look like a cross section of a lens. They pinch out on all sides in a short distance. These can actually be formal units. So can tongues. If you want a more in depth description the “North American Stratigraphic Code” actually does a good job of describing them, even though it’s a nomenclature document.

    Which orogeny tilted these? Grenville?

    • @stevenbaumann8692
      @stevenbaumann8692  4 роки тому +1

      Sorry I missed this. No. This is older than Grenville. We think it was the Mazatzal Orogeny.
