Before the developers came in, this area was pretty much wilderness. We used to ride our dirt bikes here as well as leap into the lake from it's rather high cliffs. This area was a rock quarry at one time hence the lake. Glad to see it's been preserved. Fun video mate.
I'm a mailman who has been delivering mail in the area where this volcano is. I've wondered for years the history of this volcano as I drove by it daily in my mail truck. Lately I became curious about this area and found your video. It was just what I was looking for. Now I know so much more regarding the area I have been delivering mail for years in. Thank you.
WOW! How friggin cool! I was thinking while watching a recent Nick Zentner video of Cascade geology, ‘it’d be cool if someone covered SOCAL geology in similar fashion”. BOOM! Thanks for posting! Very well done!
Wow. Great find Todd! As you told the story and then explained, light bulbs kept lighting for me. Columnar Dacite. I have seen the Columnar Basalt in the NW, but, I never thought about Dacite cooling and developing columns. Geology is made cool by teachers like you. Great Video! Oh, and thanks for not falling off the wall.
This is the best feedback you can give me; light bulbs lighting up is my goal. I endeavor to make, what could be complicated concepts, easily understandable to those not necessarily well-versed or familiar with geology.
I am an armchair geology fan and absolutely love your videos! I live in Southern Orange County. Would you ever consider hosting a field trip? Any ideas on if any geologists do local tours?
Thank you! That's an interesting idea, I'll let you know if I decide to do that. I attended a geologist-led hike at the Aliso & Wood Canyon Wilderness area in Aliso Viejo years ago, but I don't know if they host them anymore. There are 4 geologic formations there!
I live at the west end of the Columbia R Gorge. Very lucky to see all the basalt layers and columns. This video was very informative. The Nick Zintner RUclipss are amazing.
Glad to have found another geology channel covering southern California. I've been a follower of Prof Nick Zentner covering the Pacific Northwest, Jeff Williams covering mostly gold mining geology in Arizona and Nevada, plus there is Myron Cook's channel in Wyoming. Another YT channel covering SoCal is Joseph Wright, but his videos are few and far between. I've never heard of southern California volcanoes other than the cinder cones and lava fields out in the desert, so this one near Carlsbad is a surprise. I have found boulders that look like red lava up Whitewater Canyon north of the I-10 in the Mt San Gorgonio foothills, and wonder how they got there as the nearest volcanic hills are about 15 miles away and northeast of Pioneertown. I wonder if these boulders are related to the nearby Red Dome up Whitewater Canyon! Also near the entrance to Whitewater Canyon, I remember as a kid finding fossilized clams on the ridge labeled as Painted Hills. The elevation there is around 2200 feet now, but could this have been the shoreline of an ancient inland sea?
Thanks for watching! I'm a big fan of all those channels you mentioned. I love your musings about White Water Canyon; I've been there only two times, briefly, and didn't have time to really explore. So much geology, so little time.
Another great explanation and visuals. Would love to see the story of what happened from the badlands in Riverside thru the Hemet valley into Parris. 🤙
need to show the grapevine basalt triangle holding back all of the LA-Baja peninsula movement - and reason for the Richmond earthquake swarms ... as you show part of it is torn off and spun around in your video model. And how it was formed, and what is its immediate and future existence with tectonic forces being applied by the Pacific Plate, North American plate, and such remants of the Farallon plate underneath it ...
I live about an hour from Carlsbad towards LA county.. got a crazy story..I have been having (literally) the same dream for 20+ yrs (since I was 10yrs old). And it’s about lava, and it’s not a pretty dream. So I grew up terrified of volcanoes! I truly hope that volcano wake’s up. Or any dormant volcano in Cali! Have fun exploring! And you need to go to Morro Bay. Another gorgeous town with a dormant volcano and I think it’s a lot younger too 😂
Scary dream. Don't worry, no evidence that these volcanoes in SoCal will flare up. The only ones that might would be on the southern shore of the Salton Sea, but they're small and would be extensional eruptions. I've been to Morro Rock several times, which is also a volcanic plug. What's interesting is that it is one of nine volcanic plugs (some say 23!) that trend NW-SE almost in a straight-line across the landscape!
This is great. Hardly ever hear about volcanos in Southern California. I'm collecting facts about California, superlatives (biggest trees,oldest trees, tallest trees that sort of thing) maybe for a book? I read recently there are 20 volcanoes in California,some active, including the second biggest stratovolcano in the U.S. (after Yellowstone), Long Valley Caldera. Correct me if I'm wrong Just read about many eruptions millions of years ago in Clear Lake near where I live....considered somewhat recent. Clear Lake is the oldest lake on the continent. The volcanic field here in Sonoma and Lake Counties is the biggest or at least one of the biggest geothermal fields in the world,magma still beneath and steam fissures, a smaller copy of Old Faithful and a Petrified Forest of old giant redwoods one of the finest examples in the world. Once I took a field geology class all the way up the San Andreas fault,mind-blowing all the way to where it goes on the ocean around Bodega Bay. And the first seismograph in California at San Juan Bautista Mission with the jagged lines of the 1906 earthquake. Fascinating! We live in a unique and beautiful State!
Quite the field trip. Great visual to explain the transformation! Really cool perspectives. So much to see in your area....I'm starting a list.... 👍🏻 Spheroidal weathering...huh! Joshua Tree boulders are so beautiful. As always, thank you Todd.
I am encouraged to see inspired, enthusiastic science teachers, especially in geology, I majored in that at Chaffey College in Cucamonga. 69-72 My professor was a great photographer and knew his material..
Thanks Tod, great episode. Just grabbed me a really beautiful piece of Sandstone from Sand Dollar Beach on my way south from Big Sur last week. Check out the beautiful metamorphic green shiny bluff along the south of the beach (composed of serpentinite and talc?). Worthy of one of your excellent videos.
Yes! Thanks for bringing it once again bro. Excellent location choice. I had to look up the difference between tonalite and granodiorite midstream watching this LOL…pretty similar, guess the latter is “intrusive” and the former is plutonic, so hopefully help distinguish in situ. You ever make it out to Saline Valley? Really hope that your YT success continues to grow and you keep these videos coming, they are fantastic!!!
Thanks much. Good explanations. The first time I saw spheroidal weathering was at Yosemite. An easy hike up Sentinal Dome shows a huge example of the granite being weathered in a spheroidal shape. The granite sluffs off in curved sheets, big and small. Thanks also for including the Felsic to Mafic chart. Good Job.
You have family here if so next time your in town check out the waterfall below there to the north. There was another quarry there next to the I 78. Now there's a Walmart and a kohls well drive to the kohls sign and look over the fence. It was way better when I was a kid although still cool to check out. We would follow the river west through the marsh . There's still a couple of lakes there too. Actually now that I think about it the whole area is interesting. Also check out De Luz Canyon, really cool.
I did my senior thesis in geology in 1974 at San Diego State University. Did you notice that the jointing is perpendicular to the sandstone at the contact? There are pinkish red rattlesnakes like those on Catalina Island. It was a rock quarry. Nice video!
@@geologicallyspeaking On the way to Obsidian Butte or back from it, go through the San Andreas fault zone via Box Canyon at Mecca, CA. It runs between Mecca and I-10. Lots of thrusted and folded sediment layers.
very much enjoyed this video!. they say most of geologic history is recorded in sedimentary rock, but here we have some recorded in igneous rock, very interesting !
Out here where i live in diamond bar /pomona ca there is also an old volcano on the elephant hill site you should come do a video....Vee and Gary re: Pomona. South of Pudding stone reservoir (aka Frank G. Bonelli regional park) is Elephant Hill. A volcano located just east of the I-57 by the railroad tracks. W.Mission road cuts right through the center of it, you can see the cone shape from inside of the volcano as Mission turns into Diamond Bar. Gypsum can be found in the road cut. This is the epicenter that cause the pudding stone to rise and create the hills and formation to the north of the I-10. Info came from Geology class 1977.
How does this compare to Cucamonga Peak? I am from Ontario, CA, and studied geology at Chaffey College where I was taught Cucamonga Peak is a volcanic plug. When I would try to expain that to friends they didn't believe me. Also, how do the Pisgah crater and lava tubes relate to the San Bernardino Mountains?
So would I, but these typically form well-underground hidden from our view. It's only once the layers above them have eroded away that we are blessed to see their grandeur.
there are some amazing fossils at very bottom of Torrey Pines cliffs at low tide, south of the state park parking lot. The San Diego coast has risen and receded numerous times. There are beach stones all over. be cool to get some information on that.
that red mineralized rock with clasts of rounded 4iver rock looks alot like what ive been working on... I would like to see what a sample of that compared to the red Rock in the pinnacles near Paso Robles.the same material on The western side of mt whitney.... compared to the red stone in the San Juan mountains in Colorado I would like to see that all listed out I would bet there's very little difference and the same trace minerals what I'm saying is they're all connected and that's probably not a volcano igneous yes volcanic no at least not in the way that you think
Thanks for the feedback. I hope you could see the difference between breaking already broken rocks on a talus pile and spray-painting the face of an outcrop; I wouldn't hammer rock off the outcrop. Ancient cave paintings are obviously not vandalism and should be protected; I think we can agree modern spray paint is.
This could go on for a long time. I guess art is subjective so what you see as vandalism. I see it as the continuation of the human experience. Painting rocks is an ancient human thing so I'm not surprised or upset by it. I think it is just beauty that's has yet to be appreciated. That being said when my RV was spray painted by an unknown person I didn't appreciate their art. Lol. Do you protest mining, Mount Rushmore, or mountain passes? I think they dig in to outcrops for those if I'm not mistaken. I just see/feel a double standard in your animosity towards those painters. Other than that we really enjoyed the video.
Yes there's is A pattern and I see them too. But I see them differently than others. There every where. And everything around you. Books are for Dummies
Would you come down to Rosarito Baja California Mexico, I live on a cliff over looking a beach on the coast and the storms that have brought big waves and high tides has unearthed some very interesting rocks, artifacts , I think fossils... I don't know a lot about geology , I was never a rock hunter till now and that's because this private beach is littered with all kinds of incredible treasures.. The thing is the sand is starting to come back in and pretty soon it will all be covered up .. I've collected a few things but there's so much down there and I'm sure if I knew what to look for, I feel without a doubt there was an ancient city just by the artifacts I've collected , and they are surprisingly very preserved.. I'm the only one down there collecting things , cause there's no public access, but I love to get a geologist or would it be a pediologist to see if they agree about a lost civilization , I'm no professional but everything im finding says " YES!"
Awesome! Didn't know there were columns in the plug. When you showed the spherical weathering shot, I thought you had found a skull!!😂 very informative and you make it easy to understand. So glad you survived!! Mom
Just flipped your channel . And I tripped out on the fact you were in Carlsbad . I live and have been in Carlsbad since 84 . I found just by chance and watched the video .keep it up . Maybe talk about the old hot springs that are around the lower dam towards the coast .that's how aqua hedionda got its name.n
Maybe you said and I missed it. Has this volcano been mined for aggregate? That's not a "crater" that we see -- is it? Why are the dacite columns exposed?
@@geologicallyspeaking Thank you for confirming one of my occasionally correct hypotheses about geological features. :) This isn't the place for my following comment, but there really isn't a good place. I live in Anza (more exactly, Terwilliger), in interior Riverside Co., CA. I've never seen a study or authoritative book or paper about our region. Most books just throw it into the general province of Peninsular Ranges, and then they go on to describe the mountain ranges and batholith. I once read that the elevated, rolling terrain of Anza, Terwilliger, and Parks (Lake Riverside Estates) valleys was once continuous with the extensive peneplain surface of southern San Diego Co., which continues into northern Baja C. Methinks there's a PhD dissertation in our area awaiting a geology student. One specific feature I'd like to draw your attention to is Cahuilla Mountain. The mountain is notable for the sheer "granite" outcrops exposed on its south side. This feature is readily visible to the north from Hwy 371, and it's even visible from Temecula from elevated locations. It appears to me -- just my uninformed opinion -- that the mountain once presented a generally rounded profile, but that the south side of the mountain actually collapsed, exposing the mountain's "granite" core. It looks to me like the terrain between Hwy 371 and the mountain is a large landslide. But I don't know. It'd be nice if some geologist would take a look at it.
Why does basalt cool into more linear columns like crystals, is it the silicon content or something else? The dacite looks much different than the basalts, andesites, and rhyolite that I see in the PNW, it is white and there is no white rocks anywhere around Eastern Washington.
Thanks for such an informative and educational video. Loved the effort to hike up to the various locations for closeup observations. 115 like ...........
@@geologicallyspeaking Thanks, found some basic information: Columnar jointing forms in lava flows, sills, dikes, ignimbrites (ashflow tuffs), and shallow intrusions of all compositions. Most columns are straight with parallel sides and diameters from a few centimeters to 3 meters. Some columns are curved and vary in width. Columns can reach heights of 30 meters. Most columns tend to have 5 or 6 sides but have as few as 3 and as many as 7 sides.
Very interesting video ! Watching this from Norway. We have such magma / lava columns in parts of Norway too, not basalt. Strangely not even recognized. Been talking to top geologists about it, they hardly believe me. Much of the Earth's surface have yet to be explored by a discerning eye.. 🧐 🌍
Never heard the description of the transition from subduction to transform described and shown so clearly. That info-graphic should be required in all SoCal intro to geology courses.
I have always been fascinated by columns. I lived in SoCal for 50 years and never knew that I could find columns in Carlsbad. Thank you! Are there other volcanos in San Diego County like this?
I was so surprised too when I found out about this. I'm not familiar with any more columns in San Diego, but there is an outcrop of andesitic columns in Laguna Beach right on the coast (Crystal Cove State Park).
Finally made it. What a cool hike and amazing geology. The factor columns were a first for me. However I couldn’t find the flows down the hill. Was hoping to see those also. Maybe next time. Thanks for the info.
I posted an episode from here as well and plugged your channel in the pinned comment. Thanks again for all of the great info. Hope we cross paths sometime.
Es un buen video y su contenido geológico felicidades, observe en una toma del video que se encontró unas estructuras arredondeadas, puedo deducir que se trata de pillolavas, originadas en un ambiente marino, hoy en día se encuentran erosionadas, así también creo que ese volcán tuvo varias erupciones a través del tiempo por tener varios tipos de rocas felsicas con algunos rápidos enfremientos de la lava volcánica, un buen saludo desde México DF.
¡Saludos desde el sur de California! Sí, debo admitir que pensé que esas formaciones también eran almohadas de lava, pero por lo que he leído, se trata de patrones de meteorización esferoidal.

Great video hope ya enjoyed making it
Thank you for the great and informative videos! Please make more similar videos about the popular national parks! You're handsome, by the way!
North America crossed over the East Pacific ruse which may have supplied the magma but this is the most plausible source of that magma
I would think that lake would be crystal clear with all the environmental regulations in California
I had no idea that we had such nice columnar basalt in San Diego County ^^. Oh. Not basalt. I learned something. Now my head hurts, thanks a ton.

Mt. Lassen is Dacite as well. The blue rock to the right of the unconformity looks like the Paloma Schist.
Excellent video! 👍Did this volcanic activity occur at the same time as Cowles Mountain?
There was a couple mines located there, wonder what they were mining.
I see Dinos invisible to the Naked eye. Seriously I do
❤
very low grade dacite compared to the dacite of Davis Creek and Glass buttes Oregon thanks for sharing...
Thanks for watching!
How do they know that a single lonely tree stood there before the volcano came to the surface? 😛
I'm curious as to how old the pegmatite near Pala is?
Shooting from the hip here, but that's part of the Peninsular Range batholith, so around 100 million years old (+or- 20 million years).
Just built a pool right there a couple months ago. I am not allowed to fish in the lake .
I wonder what those ancient pictographs mean?
One thing I hate about these videos is they never mention how Fred Flintstone impacted the area
My apologies. I'll do better. 🤪😝😂
what type of volcano is that one? Also, its safe to say its an extinct volcano right now

12 days ago Hmm I'm part of 12 of a month
7:58 modern rock paintings by "humans" no different than something painted 60,000 ago..
Where are the diamonds? Lol
At 14:40 I see images in the stone; in center of the frame it looks like a skull and a little below, to the right, I see a man’s face.
if your not teaching you should be.
Isn't breaking rocks open with a hammer vandalism? I think so. Let's not forget cave paintings.
Thanks for the feedback. I hope you could see the difference between breaking already broken rocks on a talus pile and spray-painting the face of an outcrop; I wouldn't hammer rock off the outcrop. Ancient cave paintings are obviously not vandalism and should be protected; I think we can agree modern spray paint is.
Life World Music - You must be one of the jerks who spray-paints his name on rocks. Amirite?
If the spray paint lasts 5000 years is it no longer vandalism because it became ancient?
This could go on for a long time. I guess art is subjective so what you see as vandalism. I see it as the continuation of the human experience. Painting rocks is an ancient human thing so I'm not surprised or upset by it. I think it is just beauty that's has yet to be appreciated. That being said when my RV was spray painted by an unknown person I didn't appreciate their art. Lol. Do you protest mining, Mount Rushmore, or mountain passes? I think they dig in to outcrops for those if I'm not mistaken. I just see/feel a double standard in your animosity towards those painters. Other than that we really enjoyed the video.
@@canadiangemstones7636 no but I might have to be one now thanks to you 😉
Yes there's is A pattern and I see them too. But I see them differently than others. There every where. And everything around you. Books are for Dummies
Would you come down to Rosarito Baja California Mexico, I live on a cliff over looking a beach on the coast and the storms that have brought big waves and high tides has unearthed some very interesting rocks, artifacts , I think fossils... I don't know a lot about geology , I was never a rock hunter till now and that's because this private beach is littered with all kinds of incredible treasures.. The thing is the sand is starting to come back in and pretty soon it will all be covered up .. I've collected a few things but there's so much down there and I'm sure if I knew what to look for, I feel without a doubt there was an ancient city just by the artifacts I've collected , and they are surprisingly very preserved.. I'm the only one down there collecting things , cause there's no public access, but I love to get a geologist or would it be a pediologist to see if they agree about a lost civilization , I'm no professional but everything im finding says " YES!"
Awesome! Didn't know there were columns in the plug. When you showed the spherical weathering shot, I thought you had found a skull!!😂 very informative and you make it easy to understand. So glad you survived!! Mom
💀 Hahaha! I can't unsee that now. Thanks Mom.
@Toni &Doug
Thought I saw a skull too in the spheroids. Freaky!
Just flipped your channel . And I tripped out on the fact you were in Carlsbad . I live and have been in Carlsbad since 84 . I found just by chance and watched the video .keep it up . Maybe talk about the old hot springs that are around the lower dam towards the coast .that's how aqua hedionda got its name.n
Thank you and thanks for the tip!
Maybe you said and I missed it. Has this volcano been mined for aggregate? That's not a "crater" that we see -- is it? Why are the dacite columns exposed?
You are correct. It was quarried in the past. In fact, most of the fill to make the dam came from the volcanic plug!
@@geologicallyspeaking Thank you for confirming one of my occasionally correct hypotheses about geological features. :) This isn't the place for my following comment, but there really isn't a good place. I live in Anza (more exactly, Terwilliger), in interior Riverside Co., CA. I've never seen a study or authoritative book or paper about our region. Most books just throw it into the general province of Peninsular Ranges, and then they go on to describe the mountain ranges and batholith. I once read that the elevated, rolling terrain of Anza, Terwilliger, and Parks (Lake Riverside Estates) valleys was once continuous with the extensive peneplain surface of southern San Diego Co., which continues into northern Baja C. Methinks there's a PhD dissertation in our area awaiting a geology student. One specific feature I'd like to draw your attention to is Cahuilla Mountain. The mountain is notable for the sheer "granite" outcrops exposed on its south side. This feature is readily visible to the north from Hwy 371, and it's even visible from Temecula from elevated locations. It appears to me -- just my uninformed opinion -- that the mountain once presented a generally rounded profile, but that the south side of the mountain actually collapsed, exposing the mountain's "granite" core. It looks to me like the terrain between Hwy 371 and the mountain is a large landslide. But I don't know. It'd be nice if some geologist would take a look at it.
Excellent again! Thank you for scrambling the risky heights to get up close - great to see those joins. Cheers from England.
Thank you kindly!
Why does basalt cool into more linear columns like crystals, is it the silicon content or something else? The dacite looks much different than the basalts, andesites, and rhyolite that I see in the PNW, it is white and there is no white rocks anywhere around Eastern Washington.
Thanks for such an informative and educational video. Loved the effort to hike up to the various locations for closeup observations. 115 like ...........
Thanks for watching and the feedback. I aim to educate, entertain and please!
@@geologicallyspeaking Thanks, found some basic information: Columnar jointing forms in lava flows, sills, dikes, ignimbrites (ashflow tuffs), and shallow intrusions of all compositions. Most columns are straight with parallel sides and diameters from a few centimeters to 3 meters. Some columns are curved and vary in width. Columns can reach heights of 30 meters. Most columns tend to have 5 or 6 sides but have as few as 3 and as many as 7 sides.
Very interesting video ! Watching this from Norway. We have such magma / lava columns in parts of Norway too, not basalt. Strangely not even recognized. Been talking to top geologists about it, they hardly believe me. Much of the Earth's surface have yet to be explored by a discerning eye.. 🧐 🌍
In California I've seen columns made of basalt, andesite and now dacite! ....so far!
Never heard the description of the transition from subduction to transform described and shown so clearly. That info-graphic should be required in all SoCal intro to geology courses.
I agree. All credit to Tanya Atwater for her great animations.
I have always been fascinated by columns. I lived in SoCal for 50 years and never knew that I could find columns in Carlsbad. Thank you! Are there other volcanos in San Diego County like this?
I was so surprised too when I found out about this. I'm not familiar with any more columns in San Diego, but there is an outcrop of andesitic columns in Laguna Beach right on the coast (Crystal Cove State Park).
Its a baby Devil's Tower. It just needs a few million years.
Hahaha! Right?
That's pretty cool!
That was awesome!!! Thank you very much. My next stop when I visit SD.
Nice! You won’t regret it.
Excited to explore this area next time I am in Carlsbad. Thank you for the informative and fun video :)
Thanks for watching! Yes, give it a visit!
Finally made it. What a cool hike and amazing geology. The factor columns were a first for me. However I couldn’t find the flows down the hill. Was hoping to see those also. Maybe next time. Thanks for the info.
I posted an episode from here as well and plugged your channel in the pinned comment. Thanks again for all of the great info. Hope we cross paths sometime.
Es un buen video y su contenido geológico felicidades, observe en una toma del video que se encontró unas estructuras arredondeadas, puedo deducir que se trata de pillolavas, originadas en un ambiente marino, hoy en día se encuentran erosionadas, así también creo que ese volcán tuvo varias erupciones a través del tiempo por tener varios tipos de rocas felsicas con algunos rápidos enfremientos de la lava volcánica, un buen saludo desde México DF.
¡Saludos desde el sur de California! Sí, debo admitir que pensé que esas formaciones también eran almohadas de lava, pero por lo que he leído, se trata de patrones de meteorización esferoidal.
Cool channel bro
Thanks!
