    I'm 78 and to old to be scrambling around cliff faces but I have always had an interest in Geology. I have been following you for the past 5 years and your ability to instill excitement and knowledge is amazing. Thank you for the time you take to allow me and others to gain an appreciation of the wonderful world we live in.

    Echoing a commentator below, I've a while to go before I am 78 years old, but I am disabled by chronic illness and movement disorder. It is hard just to get around my house. I used to be an avid explorer of the world around me, walking all over, reading huge amounts. Now I can't. The videos that Mr Zentner has done, both these outdoors ones and lectures, have made a huge difference to the quality of my life. Really huge. I don't feel nearly so trapped or desperate. I've learned so much about geology generally from him that I've been able to build on it and am now able to follow and appreciate other geology oriented sites, which would not have been possible for me before.
    Nick Zentner has had such an effect on what my life is like now.

    Oh wow! I just love these field trips, It reminds me of hiking in the hills of Morenci Arizona, I remember my youth and how easy it was to scramble up a 50 ft embankment. I am 77 now and have lost that agility. too many years of office work. But Your great teaching methods astound me. You allow folks to make observations and discuss them. Which often times leads to more questions than one can answer. I love how you become part of the group, and allow all the roaming and discoveries. I can't tell you how much these videos, and kept me sane during covid. I didn't get many projects done, but dang I sure learned a lot, from watching all the 101 classes in sequence, your back porch lectures. I love your cat. Bijou. And sometimes I get frightened because your up so high. Stay agil, those kids will keep you young. I toast to you from every episode, cannot thank you enough.

    Cold air drains into the valley overnight then the heat of the sun warms the air from the top down in the morning. We were at ISU at the same time. I was getting my MS in biology. Did some remote sensing mapping of cheatgrass at INL and the Jim Sage range over by the City of Rocks. I hung out with a couple of geology grad students. I think Chris Mecham was a grad student about the time you were there. Anyway, I love the channel and getting reacquainted with geology. I've always loved geology, particularly where it is tied to plant distribution like it is. You are why the students are so engaged. Well done!

    What a story those rocks can tell.

  • @TheMcmunro
    @TheMcmunro 3 года назад +6

    Hey Prof, Love these videos. I think I know more about the PNW than I do about my own Locality. However, In the small town in which I live in Southern England, we have not only the smallest nature reserve in Britain, but the best preserved, Jurassic fossil bed in the country as well. Beaminster Fossil Bed. Folk still find it hard to understand that the trading estate was once the bottom of a shallow sea somewhere around modern day Venezuela.

    • @GraeMatterz
      @GraeMatterz 3 года назад +2

      The geology in the UK may not be as complex as the PNW but you more than make up for in anthropology. I've really gotten hooked on the Time Team/Timeline series learning about so many different civilizations, cultures and ancients there. Our ancient history isn't as rich here in the US. Cheers from across the pond!

  • @spamletspamley672
    @spamletspamley672 2 года назад +1

    What a spectacular rocky climb for the kids to be out with an expert in. I love this stuff but have been unable to get out into the wilds in decades, here in the UK, so it's great to 'go with you' virtually, on these outings.
    It would be good if you could pause at some of the plants, and let us know what they are as you go too. On this climb, the big yellow composites look very much like our 'Eastern Leopard's-bane (Doronicum). I'm a bit rusty, but, if it is that plant, it's only a garden escape here, but a Googling only gives two spots for N America. One is in Labrador, so it could be down your way too. I expect you'll know if this one is a native that you see more widely, but, if you don't see it much, then you might want to show the pictures to the plant section of USGS.
    Keep them coming! (y)

  • @johnnash5118
    @johnnash5118 3 года назад +4

    The student discussion about the adjacent rock color and texture variations was fun to eavesdrop on. If I was there with them, my suggestion would’ve been that the rock has varying alteration and weathering of the same rock formation; some oxidized layers fell off exposing the unoxidized layer beneath adjacent to the weathered rock.
    I just spent a couple hours walking the rim of Smith Rock @Crooked River Caldera, NE of Redmond, OR. The same scenario is exposed at the Rhyolite Tuff cliff walls; some sections are orange-pink next to green-grey, but it’s all the same formation.

    Hey, a local connection in Erin Donaghy! I’m always excited to hear about contributions to geology from Indiana scientists.
    Which makes me think; I always kinda wondered why people would study at a university hundreds or thousands of miles away from their project area. It always seemed counterproductive to me. Then I did my undergrad research on a drainage basin in Idaho, so I ended up in the same boat lol

      I remember telling Doc Bentley on the first day of Mineralogy, that I had read "Worlds in Collision" over the summer... His bald head turned red, and he started throwing chalk at me... for the next two years, Sweet Ole Bob would conger up his Amphibolite gods... (don't ask me, that was his thing) and say things like, but Dave thinks the earth popped out of the side of Saturn!

      I had an English teacher who decided (probably along with a lot of other people) that The Red Badge of Courage was some sort of analogy of Christ's life. I never saw it, but I sensibly fed that interpretation back on the final exam and got an A.

    21:13 looks like water formed "nodules".

    Based on information found on another website, I think the birds at 11:30 are probably Violet-green swallows. Would any of those who were there at the time like to comment?

      As I have them nesting in my eaves, I can confirm Violet-green swallows. They have a distinct call, and pretty appearance. Cheers, Prof : )

    I thought the Peshastin Pinnacles were a protected site, & had been closed to the public for just the reason that you are showing in your video...to prevent further damage to the area by rock hunters & climbers? I did enjoy this video though because I am always interested in learning more about these geological features...& I'm really not being judgmental....I just didn't know they were "open." At about 19:29, you walk past what looks almost like a boot-print on the side of the rock, which caused me to wonder if you saw any pre-historic imprints in the sandstone?
