    For people interested in the subject generally I highly recommend John McPhee's anthology "Annals of the Former World." Actually I highly recommend everything John McPhee has written but this is a good start :).

      Can vouch for his “Oranges” too! A phenomenal writer

      References to his books should carry a warning - something to the effect of:

      "may inspire circuitous road trips involving many stops dangerously examining road-cuts on busy interstate highways"

        I would pay good money for a field guide/itinerary to accompany "Assembling California".

        More directly related to the Green River, I found Wayne Ranney's "Carving Grand Canyon: Evidence, Theories, and Mystery" an accessible/engaging intro to deep geological mysteries.

      I can also recommend: "The Earth: An Intimate History" by Richard Fortey

      Second for John McPhee! Also Rising From the Plains.

    Why does this article have a picture of the Maroon Bells? As opposed to something along Green River or, ideally, the 700m deep canyon being described?

      Having recently gotten into watching documentaries or youtube videos of accounts of mountaineering expeditions it's amazing how lazy content creators, film makers and journalists can be when choosing what images or videos to show. You'll get something about climbing a mountain in the Andes and keep getting shown completely misleading pictures of Himalayan mountains, etc.

      • dylan6045 hours ago |parent

        The content you create is only as good as the stock footage you have available to you. It's not like these people are trekking to the locations to acquire their own content. If you search in stock libraries for mountaineering in the Andes, and it only brings you footage from the Himalayas you're just going to use it.

        • QuadmasterXLIIan hour ago |parent

          plenty of them are traveling, and the extent to which you see videos of people putting together stock footage indicates failure of the algorithm. although at this point, the algorithm has failed hard enough that I am down to subscriptions and chronological feed.

          Although, this larger structure did create one of my favorite internet algorithm outcomes: There is obviously intense hunger for authentic mountain videos narrated in a generic minecraft youtuber voice, and the resulting incentive gradient physically yeeted a minecraft youtuber to the top of mount everest (https://www.youtube.com/@RyanMitchellYT)

        Simple, lazy stuff like that always drives me up the wall.

        The HGTV show House Hunters used to be wildly inaccurate with their map location pins. On more than one occasion they'd say a couple is from the Bay Area but when they show the map the location pin would be in LA County. Like, come on. That's not even close.

        • toast04 hours ago |parent

          There's a lot of duplicated geographic names in Northern and Southern California. If the production house isn't in the area, it's hard, close enough.

          I lived in Burbank, but I was in the unincorporated area of Santa Clara County, not the incorporated city in LA County. Incidentally, I was living in the South Bay, but not the South Bay in LA County, or the South Bay in San Diego County.

          Anyway, perhaps the couple is from the Bay Area, but their house is in LA County right now. :P

          • PyWoody4 hours ago |parent

            A specific one that I'll never forget was actually a House Hunters International episode. It was years ago but the pin being off by about 400 miles burned it into my memory lol

            I think they were moving from Market Street to Amsterdam.

          • IncreasePosts3 hours ago |parent

            Clearly they're referring to the Santa Monica Bay Area

        • dylan6045 hours ago |parent

          Maybe the pin was closer and they were lying about it being in the Bay Area???

          Also, no need for exact location for these pins. The new home owners probably are fine with it not being exact

      • gedy5 hours ago |parent

        I think it's largely because they are "content creators" instead of trying to tell a story or share information.

        • indoordin0saur5 hours ago |parent

          I'll notice this with TV documentaries and segments on news channels quite frequently as well. I have the "GeoGuessr gene" as well as being decently well travelled so I spot this stuff all the time. One particular pet peeve of mine is movies or shows mean to be shot in medieval Europe but the "forest" they use is actually a tree plantation of North American native trees such as Sitka Spruce.

      I was confused by the image too:

      Darn AI agents, I guess they are still cheaper than interns.

      • MarkusQ6 hours ago |parent

        Sadly, they "learned" it from us. People have been doing this sort of shoddy fill work since the dawn of television (and even earlier if you count wildly misplaced / inaccurate textual descriptions).

      • terminalshort6 hours ago |parent

        Judging by the performance of AI agents at Geoguessr I suspect such errors are almost 100% humans:

    Fascinating to think of entire mountain ranges moving up and down like the skin on a wobbly pudding.

    • SideburnsOfDoom7 hours ago |parent

      And the speed at which it happens:

      > a cold, round anomaly about 200 km below the surface.

      > By estimating how far the drip had fallen and calculating the speed of its descent, the researchers estimate that the drip broke off between 2 and 5 million years ago.

      A few megayears later, the bit that broke off is still falling.

      200km in 2m years, I make that in the ballpark of 0.1m per year - a bit less if it's > 2m years, and started below the surface.

      I would like to offer a digression on silver, but as it turns out the area was occupied initially for the fur trade:

    A time lapse video would have been great.

      Unfortunately the camera was lost to flooding about 2.5m years ago, so the only visual records are some rock art.

  • phkahler6 hours ago

    What about ice pressing down? The repeated glaciations might have pushed in area down and back up several times over 6 million years. Might have even caused that drip to break off.

      It's a detailed paper by five highly qualified researchers, with over 100 citations, and thanks six different reviewers.

      It seems very likely to me that they would have said something about this theory if it were relevant.

    • wimlan hour ago |parent

      That wouldn't cause the "bullseye" pattern the article describes, would it?

      I don't think the recent glaciation got as far south at Utah, anyway.

      • grosswait19 minutes ago |parent

        You may be referring to the ice sheet, but there have been many periods of alpine glaciation in Utah. https://www.sciencedirect.com/science/article/abs/pii/S02773... and https://geology.utah.gov/map-pub/survey-notes/utahs-glacial-...

    Can we take a moment to appreciate that Dr. Adam Smith works at the University of Glasgow?
