Geologic Time is the deepest, most fascinating concept imaginable. I'd have made a fine Field Geologist.. I'm 8 months out from retiring now.
Utah is just an amazing place, her natures paint brush dainty with daubs of desert ecology and mysterious desert geology. Prof Burger is the best geology teacher in America at the moment
Great video. Thoroughly enjoyed seeing the amazing landscape and hearing about and seeing the Eocene Green River Formation. Thank you.
Regarding your comment at the very end of the video, i must say i completely agree with you about how our earth changes so much. I love the idea that the world continues to re-invent it's self, and how evolution creates new forms unimaginable to us. Things like that always get me pumped about paleontology. Thanks for the tour of the Green River, i find your videos about Utah's formations quite interesting and different from the formations here is B.C. I look forward to your next video.
Thank you very much!
Love your videos. Very informative, educational, and interesting. When I look out, across where the Bonneville Lake was, all I can see, is what a beautiful place to live, that must have been and how many civilizations, lived along Lake Bonneville's shores. That was prime, beachfront property. The lakes are coming back right now. All of the water diversion has added to the climate problems we are having. Thank You for documenting these places. They are disappearing to oil and mining. They are taking land in our National Parks and protected areas, as fast as they can.
Civilized savages that ate mega fauna instead of each other?
I've got a nice fossil found near little brush creek cave about 20 years ago.
I am exploring the area now. Thanks for the video! That old bridge is still there, seen it day's ago.
I have been there many time. Thanks I wonder what that mineral was.
Sat gas wells just west of Bonanza . The mines were always a weird feature to me.
Hey man, I found an awesome rock around 9 mile canyon area and want to prep the fossils that are in it but the rock is super hard. I bought a dremel 290 and the zoic fossil bits, but man the rock is hard. Is the green river stuff pretty much only preppable with an actual air scribe?
Thanks man, I love your videos.
good video , great dear//////
So what is behind the locked gate that closes off the highway after you cross the white river?
It’s the Enfit mine. If you take the dirt road off to the East it heads over to the ghost town of Watson and down to Dragon the old Gilsonite towns. There is also the old rail line down to Mack. The old rail cars of the Uintah Railroad and still housed in Grand Junction in the museum, but the route was pretty abandoned in the 1930s.
@@BenjaminBurgerScience thank you. It would be great if the old rail could be changed to a rail to trail.
I would like very much to be able to go look for fossil leaves and well preserved gastropods like that!! Can you message me (or reply here) where in the green river formation I could go to look for fossils so that I can prep them out and post what I did to prep them on my channel? Thanks!!
If you have not split much Green River Formation shales before, I would recommend that you visit one of the pubic quarries, like the Warfield Quarry, which clears off the shale will a bulldozer and out fits you with rock saws, at that quarry you find a lot of fish. see: www.fossilsafari.com/index.html The other option is to visit some of the STILA quarries in Utah, which are pretty covered, but I find most of the good leaves by picking through what others left behind. Stop by the BLM field office, either in Rock Springs, WY or Vernal, UT or in Grand Junction, CO and they can point you to some public quarries as well. Gastropods are super common in the Green River Formation, you can find them in beds and they tend come from any where the formation is exposed, as long as it is not to sandy. Douglas Pass is a place that is well known for fossil leaves, you can collect them from along the highway between Rangley and Grand Junction, Colorado, as there are good road cuts along Colorado Highway 139.
thank you so much!! I live in salt lake city. Do you think the regional office would be able to help me out in that same way too?
I would take a drive up to Kemmerer Wyoming, and prepare some of the fossils found in fossil lake, some of the quarries are fantastic for practicing preparing fossils preserved in shales. If you have a abrasion tool or even just prepare fossils with needles, Green River fish help you learn great ways to prepare fossils. Also check out Lance Grande's The Lost World of Fossil Lake book: www.amazon.com/Lost-World-Fossil-Lake-Snapshots/dp/0226922960
Thank you so much!! I will make sure to do that!!
Texas has lots of Gars.
Wasn't "millions of years ago", and the "lake" stretched four hundred miles, north-northwest to south-southeast, north of Price to south of Pie Town. It happened about 2,750 years ago to about 4,500 years ago. You stand over gargantuan erosion evidence, and tell us "An elephant is very like a rope!" Without knowing about gilsonite, I was saying, as I watched, it's oil shale, before you mentioned oil. Oil is an extraterrrestrial compound, one that arrived within the recorded history of Men. When rocks were "made" has little, if anything, to do with WHERE, or HOW, they are located in present times,
Earth was subjected to titanic forces (beyond those caused by the planet's mass, velocity or conditions) in relatively recent times, creating the world we know. I'm fairly certain no one, not you, I, nor anyone else, would recognize Earth of one million years ago, much less 50, 100, or 500 million. It's a pretty good bet no one would recognize Earth of only 100,000 years ago, so dramatically have things changed in the last 5,000 years. Very likely, not one of the major features we take for granted would appear. To suggest that everything has always been where it is, is to ignore evidence as plain as the nose on one's face.
Ascribing mountain-building as irretrievably ancient is to deny the conditions and signs the mountains exhibit, today. Earth went through a period of extraterrestrial "contact", probably with ejecta from a "millions of years ago" supernova that put debris in Sol's path, to be scooped up by its "net" of planet. One of these brought immense quantities of petrochemicals in a carbohydrate-rich atmosphere, one that Earth peeled off in great swaths, creating the oil fields of Arabia, Egypt, Indonesia, Texas, Mexico, Venezuela, the Caucasus, and California.
There may well be other oil fields, beneath the waters of the Pacific, or in folds too deep to recover, but the fields I mention represent oceans of oil. Interestingly, at least one astrophysicist theorizes the results of a carbohydrate-rich atmosphere interacting with a nitrogen-rich atmosphere would be carbon-dioxide to the carbo-atmo, water and crude oil to the nitro-atmo. Such an encounter would explain the amount of water on Earth, as well as its oceans of oil. It seems we have a candidate for such an event, and a wealth of anecdotal evidence to confirm it as the culprit.
You stand over a landscape riven by massive erosion, and blithely ignore the evidence. A half-trillion acre-feet of water poured over the Uinta Mountains, flooded the Four Corners area 400 miles north-south, and 300 miles east-west, to a depth of more tha 2,500 feet. The exit path for most of this water is as plain as, well, we already talked about that. How "geologists" can fail to see what happened (I am reminded of one who stood before a wall indelibly marked by water and erosion, and speculated about the creation of the tufas in the now-dry streambed, as if it were some mystery), baffles me, but it must be because it threatens the religious narrative,
That "lake" existed between 1350BC (at the latest) and 1200AD, when the Chacoans abandoned their city and left for greener pastures. Why wouldn't they? The waters that had made life possible had dribbled away to the distant Colorado River and its equally distant tributary, the San Juan. Nothing else explains WHY the Anasazi would have built where they did, at Chaco, Hovenweep, Wupatki and elsewhere, around the perimeter. They started on "mountaintops" (that probably appeared as "islands", to them), then moved down the canyon walls, for "beachfront living", and finally, out onto the prairies. When the water finally drained away, they left.
The shot at the 12:06 mark shows massive erosion by ungodly amounts of water. Yes, the strata was laid down "millions of years ago" (or billions), but much later, they were raised, cracked and carved into their present shapes. Geology as a science is woefully lacking in addressing the story of the creation of the American West, in general, and the great Southwest, in specific, confused by the welter of information, and the variety of examples and the influences of basic forces of wind, water, vulcanism and seismology. Erosion across all the area, caused by amounts of water that beggar description, resulted in the landscape we know. The changes were recent and rapid, completed in less than a thousand years, the last evidence of the causes draining away some 700 years ago. No one alive in the area survived, humans may have visited the "islands" that dotted the 2.500-mile-wide "sea", hunters venturing far from their bases in eastern Siberia (then a temperate climate)
The amazing rock formations Arches NP were not created "millions of years ago". Anyone suggesting they were does not understand how Earth's reducing atmosphere works, or what the baking heat/freezing cold temperatures of the desert are capable of doing, even to rock. I doubt more than a few of the arches will be standing, in another 1,000 years, even though I won't be around to check. We are fortunate to be here when they are jere in numbers. Every few years, another one collapses, often helped in its decline by useless humans who treat them as playthings. The wonderland of eroded sandstone and painted hills are artifacts of a time when an inland sea was rapidly evacuated from the continent (rapid being a relative term), the continent one in transition from floating chunks of crust to its current extent.
This is a very disjointed presentation
Great production and super interesting. Thanks
Amazing, thank you so much sir
Nice video, thank you. And also, you look like Dave Filoni lol
What is the name of the quarry?
Could someone spell this this black mineral for me? I cant seem to find it in any of my ID books.at 2:45 0f Video.
Its gilsonite, but also goes by the name uintahite. Its mined by the American Gilsonite company: www.americangilsonite.com/
Thanks so much. Enjoyed your vid. Subbed ya
Get yourself one of these and and a furry windscreen. You'll have to sync the sound to your video in editing, but it will make your narration audio much better for these outdoor videos. www.amazon.com/dp/B016FNEVZ0/ref=wl_it_dp_o_pC_nS_ttl?_encoding=UTF8&colid=1KCGEY7WYCVCI&coliid=I1ULCAWLL9AF3W
Thanks BJ, I have a external microphone, but I keep forgetting to use it. I love my rode microphone, but it picks up wind easy, despite a fluffy dead cat on it. I'll have to remember my external mic when I next film. Hope you enjoy these videos!
I love the videos and appreciate how much work these are to script, record, and edit!
You'll get much more consistent audio with a lav mic than with a shotgun on the camera. And if you use both, you have backup audio in case of of the options doesn't work correctly.
Wow! Look how far you can see in 7:12. We do not live on a globe. The earth is flat.
Like your brain
Also, there's a curve
