- Despite the profound changes we’ve made here in recent history, the epic saga of Los Angeles' natural history is still visible - and even striking - if you know where and how to look for it.

Not only was this out-of-studio format so enjoyable, but hearing Michelle as more of the expert she is rather than just a presenter added so much more to this video! If costs and logistics aren't an issue, hope to see more of these productions! 👏😃
Totally agree!!
Absolutely! This was a fun treat.
Agreed! I love learning more about historical places hidden in plain sight 😄 I lived in California for 23 years and never even went to see the la brea tar pits, totally want to now.
Seriously this was her best bit yet, I genuinely enjoyed listening to her the entire time - this time.
Yeah eatzqi can yr
Please, PBS Eons, more out-of-studio explorations. This was a really enjoyable variation. Thank you Michelle & Blake.
Yes! Maybe even outside of LA?
It reached another level indeed mate
I agree! Great addition to the channel
I agree👍
Yeah, they should tottally visit Pangea next
This was cool. To go more into: "Every place has it's geological tale to tell.", it would be awesome to do one of the videos. For each state!
@Solidarity Forever No, that's impossible!
@Solidarity Forever True too.
@Solidarity Forever Absolutely. I just figured this one was done in Cali, they could have one person travel from state to state, (Since PBS is a U.S. based station) while a couple travel the world? But yeah, that would take some serious Patreon donations...
yessss!! I'd love to see this in other states.
"We're going to Florida for this episode of Eons. One fact about it's geology is that sometimes it eat you." - Eons explores sinkholes
As a geologist up here in Canada one of my favourite sites is the Joggins Fossil Cliffs in Nova Scotia! A really amazing site with standing fossilized trees and many other plants and animals. Definitely would be a great place to visit for the show. Was also visited and written about by Sir Charles Lyell and then infuenced Darwin himself!
tropical plants, or temperate forest?
I live in Halifax. I used to roll my eyes and say no thank you every time anyone suggested going to Joggins. Now, after watching Eons for three years, I am a little ashamed I haven't made it yet and get so excited to explain its significance to people. I also lost my mind when I found out the first dimetrodon fossil was found on PEI. There's so much good paleontology in our neck of the woods!
I've been there. Spectacular area to view geological sediments!
Went to the La Brea Tar Pits and was surprised that there were no "pits" there and that all those large animals could be caught in a few inches to a foot of asphalt. The back site of the museum is completely undeveloped due to the asphalt pooling up in low spots, with researchers there actively digging up bones in large asphalt blocks. The museum and dig sites are completely surrounded by downtown LA. It's like a tiny patch of wilderness surrounded by urban Los Angeles. The outside of the museum always smelled like an asphalt road was being laid.
I've heard of the La Brea tar pits, of course, but I had no idea it was right smack in the middle of urban Los Angeles. Something to visit if I ever have to go there again.
........nooooooo the traffic aaaaaaaaaaaaaa.......................
Too many damn people. We need an extinction event pronto. 😵
@@ariochiv my wife and I went to LA for our honeymoon, if you do go schedule it around the free museum day in july, because la Brea is actually pretty small you can explore the whole thing in a few hours, but right next door to it is the art museum and the car museum (where Biggie got drive byed btw lmao) and on free museum day no charge for either of them.
It’s funny how it’s neither tar nor pits
@@ariochiv yeah it's like 3 minutes from Beverly hills 😳 and also if you're looking for a fun disaster movie about the la Brea tar pits, San Andreas fault, and a volcano watch Volcano lol it's good fun about what would if...
@@Googledeservestodie next time you go, be sure to go to the miniature museum close by as well. It's really cool
Please go to the bogs of Ireland! Near perfect preservation of humans from countless eras in time, and incredible animals like the great Irish Elk!! Would be an amazing episode!
Oooh, this is a good idea!
@@kiltman13 Also the hillside bogs that are a unique ecosystem created by people cutting down the rainforests 500 years ago.
Michelle's enthusiasm and knowledge throughout their explanations was really inspiring. It almost makes me want to consider doing something where I can get to geek out and explain things that surround us! I've been struggling with thinking if going back to school to research and talk about these things with other people is something up my alley or not. The ever-growing enthusiastic kid inside me makes me consider a route similar to this as a career and not just a dream. I really appreciate being able to see Michelle explain all this fascinating stuff in such a satisfyingly understandable way! I really never knew about the fascinating geology they got to walk us through.
Whats the subject(s) you would like to pick if you went back to school? What do you love geeking out about?
@@extragoogleaccount6061 It's tough for me to decide on anything, really lolol. But overall I generally like biology/ecology and anatomy, so I end up typically enjoying looking at bones/fossils and finding dead things 😅 Discovering more about those animals or plants is so fascinating, so I love to learn about them and teach others of what is known about various things. For awhile I really considered paleontology, but felt I probably couldn't find a career in it without moving away from family. But things related to animal anatomy, their evolution, and how they relate to their environments and to each other (like how things coevolved alongside each other etc) is what I generally love to think about!
Just start doing what you like but be mindful of what you need to do to accomplish it. Life will often come together for you. I'm a Gen X r I waited many years to get where I wanted to be!
I’m in bio rn. Definitely not as smart as a lot of people in the program but if you’ve got the love for stuff like this it’s worth it. You only live once
When plates collide it’s hard to tell who’s at fault.
Coming from a Caribbean island with its own tar pit (also called la brea) I'm extremely interested in learning about what animals have been discovered in tar pits around the world.
Ps: Love from Trinidad 🇹🇹
Oh rhat would be a brilliant video, great idea!!
Ooh I’d love to see that
I’ve always wondered about tar pits elsewhere and from other time periods, like imagine a tar pit full of dinosaurs
Don’t forget Tobago!
While visiting the tar pits I once saw some birds feeding on insects that were flying around above the main tar pit that is covered in a thin layer of water. One bird swooped too low and got stuck in the asphalt. Took about 10 minutes for it to go under while struggling. It was sad to watch but absolutely amazing watching the same process going on today as it has been for 10's of thousands of years!
Such a cool story, thanks for sharing!
Poor thing
Live by the sword, die by the sword.
Almost sound like a Venus flytrap, like a living thing that is able to feed itself passively
in the early '70s, i volunteered there. one day, some guests told the security guard a bird had gotten stuck in the Lake Pit. the guard (carrying a long metal rod), the guests, and i went to see the unfortunate creature. the guard climbed the fence near the bird, balanced himself on the ground/lake shore, placed one end of the rod -- um, i'm gonna end this here; suffice it to say, the bird didn't take about 10 minutes to be put out of its misery.
I really enjoyed this, going out of the studio and exploring was surprisingly fun! More like this if possible, thank you, Eons!
You almost mentioned one of my favorite geology/geography quirks of California! The same tectonic shift that rotated the Santa Monica mountains also shifted land north. Drake's Bay (just north of San Francisco) is actually geologically linked to the land around LA!
Yeah, it's on the Pacific Plate whereas most of the Bay Area is on the North American. Likewise, the landscape of Pinnacles National Park south of Hollister is part of Neenach Volcano way down near Lancaster, just north of Vasquez Rocks. And the rocks of the Farallon Islands (as well as some of the rocks visible along the old road in the Devils Slide area just south of Pacifica) are related to the rocks of the Sierras.
@Haldon; and @Andyjay729 -- Your Comments Made This Cool Video Even Better! I'm off to read more... 🙂
As a naive Los Angelo, thank you for this episode. I’ve been to all those sites, and it’s wonderful to be reminded of the long geological history of my home.
As many others have said, please PLEASE do more videos like this! It's both a really cool way to learn and a fun way to get to know the hosts better too!
Eons, y’all should do a similar field trip to the Chesapeake to show us how it was excavated by a meteorite!
Also one on the theories of how Hudson Bay and the Gulf of Mexico both got their almost perfectly round shapes.
Wait, really? How have I lived in VA my whole life and never known this? I knew that part of the Hudson is speculated to have been, as commented below, but hadn't heard that about the Chesapeake!
@@andyjay729 Wasn't the meteorite that killed the dinosaurs partially on the Yucatan and partially in the ocean (instead of making/falling along the larger outline of the Gulf)? Was there an earlier and much larger one that made the bay and the curved coastline there? (I had originally pictured the crater from the one that killed the dinosaurs ass the whole bay/coastline because of its roundness...but I thought I learned that this waasnt the case.)
I love this! Michelle's natural charisma shone through in a way I haven't seen in her scripted videos. Would love to see her do more tour guiding.
I think they purposefully try to avoid putting this in the video to avoid controversy, but Michelle uses they/them pronouns. Just a heads up!
@@Jop_pop this needs to be a main comment, thank you so much for saying this!
@@Jop_popnobody cares
I remember hiking in the Santa Monica Mountains as a child, and my father telling me how the rock strata was an ancient sea floor upthrust by tectonic forces. My mind was just totally blown. It's such revelatory knowledge that effects everything you know.
I've always wanted to visit this 'tarribly' wonderful attraction in downtown LA! Thanks for a glimpse of what it's like, Eons!
It's not exactly Downtown - more like Wilshire area and it's honestly not that interesting of a museum to visit unless you're an ice age fauna specialist. Basically lots and lots of wolf or dire "wolf" skulls and a skeleton or two of the other critters. Now if you want a grand Natural History museum, you'll be well off going to the Smithonian in DC or the one in NYC.
"tarrably". well done.
@@DogFoxHybrid and i thought it was bad when NHM was referred to as being located "Downtown"; at least _that_ museum is close-ish to Downtown L.A.
This whole thing made me so homesick. I lived in southern CA for 26 years after growing up on the east coast, and I lovelovelovelove the whole desert vibe out there. Brown, dry desert mountains are the most beautiful landscape on the planet to me. Someday, I want to go back.
Yea your gonna have to waite a while for the crime to go down....... I was gonna visit L.A this summer, and my family there said it's too dangerous.....
its a shytehole now mate
Not anymore dangerous than the late 90's, and you wouldn't have minded visiting then.
I hope you like tents and humans in their feral state of being.
The desert sands await to welcome you back, kid. You just say when
This is a great episode. I hope it becomes a series with a clever name like the "Packing Paleontologist" or something. I hope you go to the Grand Canyon, Sedona, or Mammoth Cave in Kentucky. Those places really have some exciting stories to tell.
When Michelle was explaining the angles of the rock, it was super cool to hear them speak more like a professor! I think more of these exploration videos would be fun!
Michelle really seems like one of those professors who's great at imparting their passion and knowledge to their students in relatable ways. This video was amazing, and I'd love to see more like it!
Nah I'd quit that class day 1
In the comments under their first solo video someone commented that they got geology from them at uni and that michelle was a great proff
I love Michelle, she’s amazing. She gives me the vibe of the cool science teacher in high school who made it all exciting.
Totally agree! Their episodes just carry so much joy. (Michelle uses they pronouns btw :) )
@@Jop_pop Ok. That made her instantly uncool.
Go to the lower Mississippi river valley. You can talk about salt domes, liquefaction, oil and gas deposits, the meandering Mississippi Rive and the Atchafalaya River, three rivers damn, oxbow lakes, swamps, acquirers, and all the flora and fauna, etc.
I’d love an episode exploring the human migration from Beringia down the coast of BC. I think there’s been some recent work using GIS /satellite imagery to identify shell middens of the indigenous peoples who lived in BC when the sea level was much lower. Such a diverse geology and important archaeology here!
Hi PBS Eons been really loving your podcast and hopefully you do more sessions of you guys talking together and answering questions🥰
Really like the podcast too
WOW! And I didnt think that Eons content could improve! Have always loved the analytical style of the videos, but being able to let education speak is a really interesting progression!
I started the video thinking, "Gosh, Blake is looking really tan!" Then I saw that he was doing field research in sunny SoCal and I was like, "Ahhhh, makes sense!"
Awesome video! Really interesting information and quite fun to watch, too.
I enjoy the content on prehistoric species but I absolutely LOVE the topic and execution of this video! Actually seeing how prehistory has impacted modern times is so interesting
I vote for you to go to Chicago for a future video! I took a geology course when I was a student at the University of Illinois at Chicago back in the early 90s. One part of the course had the professor taking us on a tour through the region to learn the geological history of the area, including why the suburb of Blue Island is named that (it used to be an island in Lake Michigan before the lake receded to its current shoreline), the plethora of marine fossils at an abandoned quarry, and taking a hike to follow a riverbed and study the glacial erratics scattered in the area.
Dogs still get caught in the tar-pits every now and then. In a few hundred thousand years we will be digging up Chihuahua and Pomeranian fossils and wonder what the hell happed to the direwolves.
Soooooo, this is officially your best video EVER, please do more like this, it would be excellent to see you guys out in the field whenever possible
Professor Michelle, I just want you to know that your relaxed approach acts as a welcome sign for people who'd like to know but feel as though they are not allowed to ask. Carry on.
Wonderful. More like this, please. Visiting sites and museums would be amazing.
LOL, I can tell who does more field work. Michelle runs through the crags and valleys like a little fawn and Blake picks his way carefully like an old man on an icy road.
Literally just finished a road trip through Southern California including San Bernardino national forest, Joshua tree national park, Mt. San Jacinto, and lake Elsinore. And I get home to see this in my subscription box. Perfect timing 🥰
you crossed the San Andreas, San Jacinto and Lake Elsinore faults!
It’s so fun in La Brea. I was also just using a stick to poke the bubbling asphalt and sitting on the grass when I went to the tar pits. filmed some slow motion and time lapse videos of the bubbling asphalts and literally seeing insects getting stuck in the asphalt as they hopped into those. Really intriguing to imagine how it was like when other animals were stuck at the same place I’m standing on when it was eons ago:)
"Watch out for Gorn!" 😋
I was hoping for a blooper of them doing the slow-mo Kirk/Gorn fight
This has most certainly been one of the best videos on your channel! A thoroughly enjoyable watch that will make me appreciate LA’s natural history far more!
Can't speak higher of this channel! Love the normal in-studio videos and also this new flavor! You guys rock!!!
fantastic episode!! getting to see the places really made this lesson come alive in my imagination. between this, the regular episodes, and the podcast, yall are just killing it lately. keep up the great work!
This was great! I'd love to see more of these kind of videos :)
I always love Eons, but this was one of the most engaging episodes by far!
It's especially cool hearing the presenters talking about their passions in such an easy-to-follow format. They all have such fantastic energy
This was amazing!
Thank you for this wonderful tour, cheers bro
Loved this episode! Would love to see more like this!! Always makes my day to see a new video from ya'll!!
This is interesting and fascinating
LOVED this video!!! i love pbs eons so much and the hosts!! i get so excited every time a new video gets uploaded
this channel is everything! thanks for keeping up the quality vids and podcasts, squad.
This video is truly spectacular and well made!!! Greatly explained… could listen and watch these videos all day long!!! One of the best channels out there on CZcams!!!👍🏻👍🏻👍🏻😎😎😎😎
I like this new format. More please.
An outstanding video from an outstanding team! Thank you so much, PBS Eons!
PBS eons you all rock! Eons and deep look are my fav pbs productions out of anything. So educational and you can tell they are both so passionate
Great new format guys, i really enjoyed this one. Hope to see more of these in the field videos once in a while.
Wow I learned so many new things because of this video. Amazing job as always.
I've always had trouble grasping the immense scales of pressure, time, size, and force when it comes to the mechanisms that power tectonic activity. This helped immensely. Thank you
One of my favorite episodes of this show!! Very well put together, informative, and fun.
Aw, yall look like you had a blast filming this on location! I hope you get to do more of these, this is a treat
Definitely do more of these for other Mountains and features like the Appalachians, Rockies, Volcanic Mountains, etc.
In my four trips to the US I've been to Rancho La Brea twice: the first time as freshman geology student, the second as a working geologist/paleontologist. Both visits were unplanned though, so next time I'll be sure to write ahead of time to see if I can actually interact with the resident geologists and paleontologists there.
Please do! We’d love to have you visit our crazy city! 🫠
Loving this new more in-depth format. Keep them coming!
I loved this so much. Watching you two interact and just geek out on the geology (which I normally find boring in isolation, but found fascinating in the context of LA and La Brea) and natural history.
Really good segment, wish it were longer
Fantastic video! It brought back many memories of exploring the area when I used to live near Vasquez Rocks. I would also take guests to the tar pits and hike the Santa Monica Mountains.
Also, when you are looking for the fault up near Palmdale/Lancaster, Lake Palmdale on the east side of CA-14 is a sag pond, so that's the fault line.
Honestly, my favorite episode yet! More episodes outside of the studio please!
This is absolutely my favorite episode you guys have done yet. Id love to see more off the cuff, field trip, interview style episodes
Loved this episode. More field trips, please!
This was an awesome episode
This channel is one of the most wholesome, educational and entertaining on CZcams. Please keep going guys!
This chanel is soo underrated. All the content is soo great. Deserves to be super popular. Keep the great stuff coming forever please.
This was really fun!
Y’all should check out the painted hills in Oregon. Also, I love how y’all did this video, keep up the good work!
Absolutely loved this video. Seeing you guys out and about made the video so more engaging.
This was such a fun video, you could feel the passion oozing from it. Id love more of these!!
I would love to see y'all do a series of america like this! Exploring all the states different geological tales.
there was another PBS 3 episode show, "Making North America" that covers various parts of the US... search for : nova making north america
It's also part of the Transverse Ranges, but I'd love if you'd do something on the Topatopa Mountains specifically, especially in the Ojai Valley. There is such interesting geology here: an enormous bluff (after which the mountains are named) with visible strata that is horizontal but upside-down (older rock on top); a waterfall at over 3000ft elevation that's made out of fossilized coral and around which you can find fossil oysters from when the whole area was underwater; near there, a view toward the ocean where you can see the California Channel Islands as though they were just another ridge of the mountain range, because they actually are! I have also heard a theory that the Monterey Submarine Canyon originally formed at the mouth of the Channel before being pushed further up the coast, as there is an enormous submarine waterfall at the mouth of the Channel; part of that theory involved the Colorado River having once emptied through what's now the Santa Clara River basin, across the (then-above-water) Channel floor and off the continental shelf, down that (now-submarine) waterfall into (what's now) the Monterey Submarine Canyon.
I've been to Monterrey & one of the Channel Islands (along with all the NPS properties in the lower 48 + all but Molokai in Hawaii), but I don't think I visited any of the other features you mentioned.
It sux a bit to find out that there's so much - and sometimes more interesting - geology, geography, anthropology & paleontology that's not incorporated into those parks/sites.
Guess I'll just have to start a new list and do it all over again. Thanks for the info!
I love the typical format of the videos on PBS Eons but this was such a fun treat to watch. Would love to see more out of studio features with experts in future!
This episode was SUPER fun and SUPER informative, it is amazing how you managed to do both! Michelle's personality got a lot more room to shine! Amazing episode.
This was great! Would love to see you two wander the rainforests anywhere in the Pacific Northwest? Thanks for everything you do!
There are rain forests in the north west?!
@@Alusnovalotus Temperate, not tropical, rain forest.
@@Alusnovalotus Like Gillian said they are temperate rainforests but to my Canadian self they are still very much rainforests and contain some of the oldest trees in North America (like 2000 years old old!)! They are SO special! I highly recommended looking them up! They also contains elusive sea wolves, and the immensely special Spirit Bears.
_"Every place on Earth does have its own unique geological tale that's just waiting to be told."_
So true. I'm living very close to the Neandertal valley in Germany where the first Neanderthal hominids were found. But this fact makes a lot of people overlook the fascinating geological story of the valley itself which of course is a lot older than the Neanderthals who lived here 40,000 years ago. This valley was cut by a creek into calcite rocks that were formed from corals living in the shelf sea near the coast of an ancient continent, the so-called Old Red Continent 380 million years ago.
And for you Americans: Big parts of the Old Red Continent went into North America. So if for example you are living in Maine you can rightly claim that the Neandertal was not that far away in the past because regions of your home state once were coastline of the Old Red Continent. And if you would have gone scuba-diving there 380 million years ago you would have seen the corals that later formed the valley that gave its name to the Neanderthals (and that can still be found here in the valley if you keep an open eye).
Excellent Video! Thank you, Michelle & Blake! You two make an great team!
Do more of these, this was highly entertaining. Literally anywhere, I don't even care, but this format is fantastic!
I absolutely loved all of this. PLEASE do this more often, i loved hearing Michelle talk about everything. They clearly are very knowledgeable and comfortable with the material and just so charismatic. I always thought they were awesome but this made them an even bigger star for me! More out of studio travels, bonus if they're with Michelle!
Edit: found out Michelle uses they/them pronouns.
This format is really, and I mean REALLY GOOD, enjoyable and refreshing! It has that Great Big Story vibes to it. Keep these up please!
honestly this was one of my favorite videos y'all have ever done
It was really nice to have Michelle as a teacher she did a really fantastic job of explaining everything, your normal in studio videos are awesome but this is fantastic aswell !
Thanks
Thank you for taking us on such an interesting trip!
Who knew that tar - asphalt - could be so interesting?
Or fun? (Well, now. Not back then so much...)
This is so cool. Love it. This was fun. Would not cry if you made more of this.
This was wonderful!! Great job to all involved, I loved the out of studio vibe of this one, could definitely see a recurring maybe monthly, bi-monthly situation being super interesting!! Take care!
Nice, I really enjoyed the longer format of this episode, hopefully you can do more in the future? Interesting stuff too, the geology there is dynamic [and still active] plus the tar pits are fascinating.
Thank you.
The main reason I want to visit California is to see the La Brea tar pits
I love it there
I went there as a teen on holiday, it was incredible. California is like a giant amusement park, where there are so many incredible places to visit that can be realistically visited within a vacation timeframe. It's not to horrifically spread out, remote like my own country [Australia].
Even our great barrier reef is a 3 hour boat ride from the docks. lol
This was incredibly well done and the out-of-studio experience is a wonderful change from the in-studio experience. I agree with another who commented that if costs and logistics aren't too much of a challenge that it would nice for future episodes to also be out-of-studio experiences as well. Thanks so much for everyone who made this experience into a video. The host and his friend was truly remarkable as during the video the banter was wholesome. :) Lastly, I want to thank you all again for doing your research and giving credit to the indigenous folks and their land.
If any teachers watching this channel, please ask your schools to allow PBS Eons in the Geology classes.
These videos are very informative and easy to understand against all those almost futile efforts we put into understanding only by reading those geology textbooks.
Loved it! And big thanks to the blurb at the end recognizing native land and practices.
This was great fun
Loved this one. Having spoken about the la brea tar pits in so many videos previously, it was lovely to be taken there to see and explore it
Brilliant and fascinating video! (as always). Please do more like this one!
who needs sleep anyway this is better
✋
lmao, my brain wants to rest ha
Where are you fools from the dark side of the moon? It's daytime on my side.
@@J.M.415 i am from india its 3:22 am
I enjoyed this variation on the standard Eons content. If you ever do something like this again, may I recommend Cincinnati? I visited the Caesar Creek Lake spillway earlier this year, and you basically can't find a rock that isn't an Ordovician fossil.
A brilliant episode! Very informative and nicely entertaining. Much as I love all of your output, more field excursions like this please! Greetings from the UK.
one of the best episodes ive watched so far from this channel
“La brea” is Spanish for “The tar”, so these are: The The Tar Tar Pits.
