- Free Museum Admission + An Evidence Based Assault on Geologic Time!
This meetup is rebellious! We'll use the Devonian Sea exhibit to visualize the drowning of the super continent(s) and then the plate tectonics displays to see the subsequent break up of the super continent. The "rebel geochronology" presentation will reveal the undisclosed origins and history of the concept of geologic time while challenging the concept based on field evidence both locally and globally. This fast moving presentation combines the last two topics presented in a Friday night and a Saturday afternoon session. The "auditorium" is small so we can only get a small group in on the "rebel" presentation. If you don't get in on the RSVP wait list in time to take in the presentation on "The Legend of Geologic Time," you can still see the museum for free this day only! Use this link to download a free ticket for admission for two to the Nevada State Museum good all day, but only on the September 21st; https://www.smithsonianmag.com/museumday/museum-day-2019/ When the submerged continent resurfaced, marine organisms of all sizes were preserved briefly in interior drainage basins (i.e. the Great Basin in North America). The largest of these would wash ashore in central Nevada to become our state fossil, the 70 foot long Shoshone Ichthyosaurus. Both a little noticed display narrative and your drive to the state fossil park will also challenge the traditional view of geologic time; was the Devonian sea epoch really 300 million years ago? If so, where is the observable evidence for the time lapse? Our free tickets are connected with Smithsonian Magazine's Museum Day. Their May issue last year featured China's dinosaur boom; https://www.smithsonianmag.com/science-nature/great-chinese-dino-boom-180968745/ China's Gobe desert has been described as topography untouched since the Jurassic. This image of unbroken dinosaur eggs left unbroken in the mud parallels the Great Basin where our state fossil is found emerging from the surface strata where dozen beached. Steno's Principal of Superposition holds such surface fossils to be relatively recent, yet the accepted "absolute" dating systems of the 20th century based on igneous rocks date dinosaurs between 65 and 200 million years while recent carbon 14 dates them at less than 40,000 !!! Come early to take in the whole museum and then circle back to the meeting room at 2 PM. Q&A following the rebellious geochronology presentation!
- Sinking a supercontinent and the biggest break up ever!
Last month by our own Marvin Katz delivered the series opener on Plate Tectonics at the beautiful Galena Creek Visitor Center. Friday night the 19th we'll re-examine the conventional geologic timescale in South Lake Tahoe. This stop (Saturday afternoon) we'll use the Devonian Sea exhibit at our state museum in Carson City to discuss the submerged super continent and see how plate tectonics played a role in the subsequent break up of the super continent(s). When the submerged supercontinent resurfaced, marine organisms of all sizes were preserved briefly in interior drainage basins (i.e. the Great Basin in North America). The largest of these would wash ashore in central Nevada to become our state fossil, the 70 foot long Shoshone Ichthyosaurus. The "tour" will begin and end in the "auditorium" actually a class room near the mammoth display on the second floor. Both the cause of the ice age and the world wide extinctions of ice age mega fauna will be linked to the source of catastrophically rapid continental drift. Come early to see the rest of the museum before our 2:30 meetup. The $8 admission charge is for entry to the museum.
- The Legend of Geologic Time?
Is radioisotopic dating a theoretical process? Does it work on historical lava flows (young rocks)? Does diamond formation really require hundreds of millions of years? This intimate forum will rock your wold view as the 20th century notion of geologic time is put on trial! The implications of this radical "young earth" perspective will be examined at our next meetup held the next day at the Nevada State Museum in Carson City using exhibits on plate tectonics and wildly rapid continental drift to explain the previously elusive cause of the last ice age.
- Get the (continental) drift of Plate Tectonics!
Geology/Plate Tectonics: Have you ever wondered how and why mountains form, why there are earthquakes, or why there are volcanoes? At this talk we will discuss Plate Tectonics which is the theory that rigid portions (plates) of the surface of the earth move with respect to each other. Because of this motion, many topological features such as mountains, volcanos, and faults on the surface of earth can be understood. Inside the beautiful Galena Creek Visitor Center, 50 minutes of amazing photos and diagrams from our own rock star, Marvin Katz, drawing on his life long career spanning mining, petroleum and environmental geology will be followed by a brief outdoor discussion of local rock and related mountain building processes (orogeny). Consider bringing a cool drink and hat to supplement the sunglasses for this part.
- Rock talk with the real deal at the perfect place!
• What we'll do In a private meeting room one the second floor of the world class Keck mineralogy museum (https://www.unr.edu/keck) our own rock star, Marvin Katz, will give us a deeper look (than last year) of how geologists identify and classify rocks by mineral content and formation processes in three DIFFERENT two hour sessions. Mr. Katz's career path as a professional geologist spanned several different industries including oil, environmental and mining, but his easy going casual style connects perfectly with our members. Every two hours a different classification/type of rock will be covered per the schedule below. In between you can walk back down stairs to get a guided tour of the W. M. Keck Earth Science and Mineral Engineering Museum from Garrett Baremore, the museum curator. This is Nevada's oldest geology museum and this is the way to see it!! Seating is extremely limited for each rock talk, so any RSVP after the first 30 is strictly on a space available basis! Seating will be by order of RSVP received for each session you specify. If you can't get a seat in the room, you can still take the museum tour at 11 AM or 1:30 PM. In any case we recommend you sign up for Baremore's Mineral Monday at the website above! This museum has never charged for admission and we are not even paying for the early access or the meeting room, or the group tour, so I would ask for generosity as we stroll by their donation box during the tours. • What to bring Notebook, hand lens (loupe), pen and a donation for the museum. Maybe a protein bar if you're missing breakfast, but definitely a sack lunch if you're doing both morning and afternoon sessions. • Important to know There will be three different sessions, one for each type of rock so you must indicate which session(s) you will attend (by start time) as space is limited to 30 in each and this event totally booked out twice a year ago when we had one third our present membership!! The sessions are as follows; 9 AM to 11 AM IGNEOUS (formerly melted) rocks 11:30 to 1:30 SEDIMENTARY (formerly "mud") rocks 2:00 to 4:00 METAMORPHIC (a.k.a. "mushed") rocks
- Nevada Paradox: the driest state's fossil park is a heap of giant fish!
Berlin - Icthyosaur State Park
Check out our destination at http://parks.nv.gov/parks/berlin-ichthyosaur Is there a connection between the recent Great Basin water levels and the concentration of prehistoric marine fossils on a hill side that was supposedly sea floor during the Jurassic? Why are the same fossils found beneath a retreating glacier atop the Chilean Alps? 🗻 Last week we challenged the 20th century notion of geologic time at the Nevada State Museum in the historic Carson City mint. This trip continues that investigation by examining the topography between our state fossil site and the surrounding dry lake beds of pluvial Lake Lahontan. Both are former marine environments, but supposedly separated by 65 million years according to the geologic time scale. 🔍 The fossil shelter is still open weekends for tours at 10 AM and 2 PM. Our 1 PM meet up at the fossil shelter will apply fundamental principals of site forensic analysis to the field evidence that radically challenges the conventional dating of Jurassic fossils. Driving to and from the fossil park we will be on the lookout for evidence of the lapse of 65 million years. For those wanting to camp Friday night at the fossil park (Elev. 6,800 ft) we will meet in route at Grimes Point for sack lunches at noon and again at the historic Middlegate Station at 2PM. In between (Fallon and Middlegate) watch for benching caused by the wave action of prior water levels on the hills to the east. Park admission is $5 and the campsite is $15 (both cash or checks only). For those that have been asking for a mine tour; I haven't been able to confirm these are still available for the Berlin mine, but the ghost town sports over 80 interpretive signs along the dirt road and foot trails.🎒 Call (775)[masked] for ride sharing from Carson City or Fallon.
- Waterboarding a supercontinent and the legend of geologic time!
This meetup is both learning and planning! We'll use the Devonian Sea exhibit to discuss the submerged "waterboarded" super continent and the plate techtonics displays see the subsequent break up of the super continent(s). Use this link to download a free ticket for admission for two to the Nevada State Museum good only on the 22nd; https://www.smithsonianmag.com/museumday/search/?q=&kinds=Science&kinds=Zoos%20%26%20Gardens&kinds=Natural%20History& When the submerged continent resurfaced, marine organisms of all sizes were preserved briefly in interior drainage basins (i.e. the Great Basin in North America). The largest of these would wash ashore in central Nevada to become our state fossil, the 70 foot long Shoshone Ichthyosaurus, hence our tour guide will be wearing a fishing vest and conclude the tour at the Ichthyosaur reproduction display around noon. Our meetup will then finish by laying out the details of our field trip to the state fossil park October 13th at Berlin Ichthyosaur. Afterwards you are free to roam the rest of this museum which was built as the Carson City mint from stones quarried nearby when Nevada was admitted to the union. Both a little noticed display narrative and your drive to the state fossil park will challenge to the traditional view of geologic time; was the Devonian sea epoch really 300 million years ago? If so, where is the observable evidence for the time lapse? Our free tickets are connected with Smithsonian Magazine museum day. Their May issue features China's dinosaur boom; https://www.smithsonianmag.com/science-nature/great-chinese-dino-boom-180968745/ China's Gobe desert has been described as topography untouched since the Jurassic. This image of unbroken dinosaur eggs left unbroken in the mud parallels the Great Basin where our state fossil is found emerging from the surface strata where it beached.
- 🔦 Tour Hidden Cave and see 800+ basalt boulders with ancient petroglyphs! 🔍 🌋
• What we'll do Walk fast to survey this excellent rural museum, then sit for the 9:30 AM short video on Hidden Cave. The actual tour of the cave leaves immediately after the video by heading out to the trailhead which is 1/2 mile up the dirt road that starts at the Grimes Point Archaeological Site 11 miles east of Fallon. The easy 30 minute hike takes us past the first two petroglyphs, and a couple tufa rock shelters then we break into groups of 15 - 20 to enter and tour the normally locked cave. It is thought that the cave formed by wave action during the ice age. The ceiling collapsed later. We'll theorize about what the cave entrance looked like during the Mount Mazama eruption 🌋 whose ash layer is visible in this picture of the excavated strata inside the cave. http://ccmuseum.org/hidden-cave-tours/ For those with sack lunches, we'll regroup back at the Grimes Point picnic tables to eat and report on the prospects for an upcoming mine tour Meetup. By 1 PM we'll break up to take advantage of three nearby attractions; 1) The adjacent petroglyph trail through the extensive and mystifying collection of ancient lake front rock art. http://www.americantrails.org/nationalrecreationtrails/blm/grimespoint-nv.html 2) Head east back up the dirt road in search of wonderstones at wonder Mountain. 3) Drive further east on US HWY 50 to see alluvial fan formations at the mega dune; Sand Mountain https://www.blm.gov/visit/sand-mountain-recreation-area • What to bring: sack lunch, warm coat, comfy walking shoes or boots, and a donation for the museum. 🎒👟💸 • Important to know; don't dally after the movie, stay with us or follow the guide and go immediately to the trailhead for sequencing. If necessary; get fuel before arriving at the museum. To carpool from south Carson City be at the Costco gas pumps by 7:30 AM. 🚙
