I spent my childhood on a pineapple farm in Beerwah under the shadow of Mount Tibrogargan. The soil in the area is red and rich in volcanic iron. Really wonderful place
My great uncle, Sidney McIntyre, developed a farm near Beerwah after WW1. I love the Glasshous Mountai a, most especially Mt Tibrogargan. It just about my favourite part of my favourite place on Earth.
Probably a good call not to attempt to pronounce some of the more difficult names like Ngungun or Mikitibumulgrai. Mount Tibrogargan sits right next to a railway and I used to look at it out the window of the train heading up the coast every week. Beautiful landscape.
You inadvertently answered a question I've had about Australia zipping around the planet and hot spots. I was missing that piece of the puzzle! Thank you!
@@GeologyHub Are you referring to the offshore hotspot chanis such as the Lord Howe rise? They are a fascinating part of the whole Coral sea region volcanism/ tectonics and tell a great story. Research in the 70's and 80's found evidence of hundred metre high tsunamis on certain parts of the east coast of New South Wales, speculated to be from volcanic island flank collapses.
I watched a video by Oz Geographics on this just a few days ago. He claimed that Australia traveled over the hot spot and a chain of volcanoes were produced throughout what is now Queensland, New South Wales and Victoria.
I live in this area. To see the size of these mountains and know they were formed by erosion is mind blowing. The mentioned Mount Coolum is huge and very imposing.
As a biologist who spent his life working in chemistry, It still amazes me that trees can grow on bare rocks like this. One feature I would like to see covered here. On a trip to Arlie Beach in the middle 90s we visited an above ground dry cave near Rockhampton. On the top of this cave was a 1 meter high tree that had roots that went through the cavern and then another 30 meters down into the ground. The 50mm root came down the exact centre of the cave. The cave was used as a recording studio at times, and the cave had a 10 watt sound system that filled the cave with music so that in the total darkness you can not tell which direction the music comes from. Rather the sound surrounded you. I don't know the name of the cave now, but that was an awesome experience. My first and only time in a dry above ground cave.
Hi, @jayjaynella4539, I lived out at The caves for some time. The place you're thinking of is Olsen's Capricorn Caverns. The large cave you wrote about is the Cathedral Cave, famous for hosting weddings, church services, and orchestras. I spent a lot of time exploring caves at the Mt Etna National Park (off the tourist path). It's a fascinating area with a very interesting history. There were two separate tourist ventures out there but one family donated their caves and land to National Parks many years ago.
@@BradGryphonn Now that seems right. I heard the tour guide mention something about cathedral. So I will assume it is this rather than Mt. Archer. Although on Google earth the description says underground caves. But GE shows 2 Mount Archers in Queensland, one near Rockhampton and the other near Sunshine Coast.
I know before you said that every state in America has had volcanoes at some point in their history, I was wondering if you could give us a series featuring each state.
I've been trying to figure out what surface features in Rhode Island could be volcanic. There are many erratics, and the sand dunes in West Greenwich, all which are remnants of the retreating glaciers from the end of the last ice age. There is the landfill mountain in Johnston. Some have predicted it will erupt one day. But, I seriously doubt vulcanism will have anything to do with it.
@@respectbossmon I have never known any history of volcanic activity in Rhode Island, but I know its the only New England state to be formed entirely on top the bedrock of the former microcontinent Avalonia, which was a volcanic arc that rifted off Gondwana & became an independent drifting landmass.
OzGeographics (another RU-vid channel, primarily Australian OFC) recently did a show on this topic. While I prefer more the more wide ranging topics covered on this channel, home grown stuff (I'm Australian) also interests me, so I'm giving them a shout out :p
I am taking a geology class and I already know some of the terminology they are teaching me because of your videos. And I now am beginning to understand more of the stuff you are talking about haha
Oh man I wish YT had been around in the 90s. Some of the stuff would be confusing and wrong but you can get a breadth of understanding we simply couldn't.
I took geology in college it was fun i really thought it taught me alot. I was wrong. 8yrs later I discovered something that changed everything. Geology is a lie. Oh thats an ingenious rock that came from the earths mantle....? Bitch please you aint never been to no mantle. Oh it came up through a volcano...? What? The only thing you're going to get is obsidian, pumice an sedimentary rock. Whole unbroken rocks are biological born from seed. I know its not what we're taught but ive been studying it for the past 4yr. There is a reoccurring lattice type pattern that runs throughout whole Rocks that science doesn't acknowledge. Rocks are like root berries the start out soft bodied and round. But being under the dirt most time they get squished before they petrify. But since they come from trees they do petrify. Where there are lots of trees. There are lots of rocks. Places like the desert there are no rocks because there are no trees. This also explains geodes and thunder eggs. Water didn't get inside the those rocks to form crystals. The water was already there. Bigger rocks came from bigger trees. Another peice they wont tell you. Go Google tree cells under microscope and look at the hexagonal characteristics. And then go look at devils tower in Wyoming. Or giants causeway in Ireland. You'll find the same hexagonal characteristics. And you can find the same hexagonal characteristics in many many places around the world. They were ancient trees. The trees of life. Now this is truth for you to do with what you please. But UNFORTUNATELY YOU WON'T LIKLEY PASS YOUR CLASS IF YOU THIS INFO. because school is for indoctrination not education. They don't want a nation of thinkers. They want a nation of obedient workers who don't ask too many questions. They want you to read the books and mark the answer that they tell you are correct. Anyhow I know it sounds a little crazy but. It also makes perfect sense. Its just not what they want people to know. Because giant trees give credit to God, giants and perhaps jack and the beanstalk😂 their trying to teach everyone that God doesn't exist a Like I said. Just research devils tower and other locations with the straight hexagonal basalt structures. Believe whatever you want to believe. But if you do the research I believe you will understand and find that the same as I did. That these are not old volcanos. But very big very old trees. ✌
Ive been waiting for you to make a video about the Glass House Mountains! I live around them and have gone abseiling down one before, When your up there the view is amazing and the mountains have old lava flows you can walk on, Really amazing to see. Also congrats for saying the place names right! haha
Thank you. My wife was asking about these on our cruise out of Brisbane (feb19/22) As we pasted the Sunshine Coast she asked why they look different. 👍🏼
Seconded! The Warrumbungles are a more recent product of the mantle hotspot that created the Glasshouse Mountains. They are especially spectacular because they rise out of an otherwise quite ancient plain. There's also Mount Warning, south of the Glasshouse Mountains that is another hotspot product between the Glasshouse Mtns nd Warrumbungles . And immediately north of the Glasshouse Mountains is the Blackall Range, resulting from a capping of basalt (some great columnar formations!) that protected it from the erosion that eventually exposed the Glasshouse Mountains.
Thanks for a great video about the Glass House Mountains... they are about an hours drive north of where I live. I love the profuse spring wildflowers in the bush around the mountains from August to October.
Mt St Helens is building a lava dome in its caldera. Complicating the dome is a glacier, which is adding to the dangers, should there be renewed eruptive activity at MSH.
Oregon here.. What's incredible to me is Washington State's (government) blind eye to the danger Mt Rainier poses. There was a PBS documentary about the eminent threat of mudslide or lahars that have traveled to Puget Sound, and in the decades since, they've allowed hundreds of homes to be built on the top of the flows!
I’d be very interested in a segment explaining the current thinking of what the source river for the Monterrey Bay Canyon is. This canyon is as big as the Grand Canyon but, because of the San Andreas transform fault the source must have been further south. What are the current theories to explain its genesis? Thanks for considering this and keep up the great work. It’s always very enlightening.
Please cover the area of tambourine mountain and the thunderbird thunder egg park. It was a great place when i was a kid. Still have a few amethyst geodes from there.
Topic: Picacho Peak in Arizona. A landmark on the commute between Tucson and Phoenix. At first, it looks like an old volcano core, where the outside has since eroded away. However, instead it seems to have somehow spilt away from the remaining Picacho mountains. I have heard that it was also used as a bombing target for military training some years ago.
There is another odd mountain in far north Queensland called Black Mountain, it is a mountain made of massive black granite boulders near Cook Town, formed from cooling magma 250 million years ago (give or take a year) it looks like a huge pyramid of boulders.
I love how your narration is like timeless in nature describing how some eruption occurred around a town a million years ago that exists there now but didn't exist then and how you continuously compare volcanoes to my favorite volcano mt Lassen!! At some point I hope to upload my videos I filmed there. Our power is out again due to California's weather right after they assured me it would not go out while I was filming them and I'm so very annoyed, luckily we could use one phone to watch videos and we watched yours first.
Hey this was great thank you. I know that area quite well and have slowly been learning about the geological history. I assumed they were part of the plate movement over the upwelling 50M years ago that resulted in Wollumbin (Mt Warning) and helped to shape NZ. Seems like my simple explanation was too simple!
You stated that the volcanoes eroded, but didn't mention uplift. Wasn't there uplift as well as erosion to put the magma chamber above sea level? It's interesting that you say rhyolite doesn't spread far, because I've read that much of the volcanic sections of the McPherson ranges which form the north-western part of the Mount Warning shield volcano remnant are rhyolite. The Mount Warning complex must have had numerous vents, because aside from the core at mount warning, there's basalt column formations at Minyon Falls and Fingal Head. Mount Warning being a shield volcano, I'd have expected the lava to have a low viscosity like the volcanoes in Hawaii. Mount Warning seems to be a magma chamber remnant like Beerwah, but much bigger, reaching 1156m in height. The original height of the volcano was around 2300m.
Consider making a video about the chain of prominent volcanic plugs near Moro Bay, California. Or the unusual geology and geography of the Transverse Ranges.
I live about 400klm north of there in Gladstone and we have our own extinct volcano Mt Larcom. It looks like a normal mountain but with an exposed larva core at the top. I work in earth moving and the geology in the area is amazing the deeper you dig.
Please make a video about Trindade Volcano in Brasil. It is listed as active on Volcano Discovery but I could not find any reliable information of it being active or extinct. As it erupted 50k years ago it seems plausible that it can erupt again. It can be our only volcano.
I long thought Beacon Rock on the Columbia River formed in this way, but after your feature about Haystack Rock at Cannon Beach, I thought I might be wrong.
Hi, Are the Three Brothers and Jolly Nose volcanic plugs formed by the Comboyne Volcano? Comboyne Peak, Big and Little Nellie and Flat Rock almost certainly are.
Thanks to you im really interessted into Geology, i try to combine my job, in Biology, with Volcanology in the future! Now my question, i come from the southern part of Germany and we dont have active vulcanos here but a inactive vulcanic field. The Hegau Vulcanos, could you by any chance make a video about it or is it simply to small and too old and all the information is in German? keep up the awesome work and life the dream!
I understand there is a seamount off the British Columbia coast that erupts fairly often and is getting near the surface. I would be interested in a video on that and on other seamounts almost ready to form islands, like the one in the between Sicily and Tunisia that surfaced for a while in the 19th century.
Bro, I actually had a dream last night that a volcano erupted near my house, Well atleast I saw it, And it also felt so realistic, But then when I woke up this morning I didn’t see any volcano looking mountains anywhere.
has anyone actually been in any of the extinct magma chambers or do the fill in or solidify? The way it's presented it looks like it would leave 'caves'. As you can tell, I know nothing about the subject really but am quit interested.
They are not geological oddities they are the houses of the ancients. I can't take anymore of this. If you want to know a load of nonsense about history and cosmology ask a geologist.
"Towering" is being very kind. The tallest mountain in Australia barely scrapes past 7,000 feet. The continent is a pathetic mixture of searing desert and unappealing scrubland.
