The Northland Volcano that Disappeared

[@julescaru8591]

You have painted a magnificent picture , in my mind’s eye, of the landscape of the past , that must’ve been something to see!

Cheers!

[@Itssmial_Ova]

Great video, My absolute favorite NZ channel. Often I'm out there out and about and looking at geological features and I think to myself "Damn, I really wish I knew a Geologist to explain what I'm looking at" I had that Exact thought driving down that road and looking at that exact same geological feature! Thanks a bunch! Next time I'm that way I'll appreciate it all the more. I LOVE Geology and thinking about DeepTime, It really makes you appreciate how finate and precious our time on earth is.

[@OutThereLearning]

Thanks for your kind appreciation!

[@treblepet]

Nice surprise - I was on top of the first one some years ago, and am now learning how that came about. Your description also augments my understanding of how much gets eroded away, which now places the Mamaku area near Rotorua in a clearer light. LOVE this channel - please don't stop!

[@OutThereLearning]

Thank you for your interest

[@lindakayjohnson9434]

Damn! It'd take QUITE awhile for me to catch my breath after summiting that! Kudos..and thanks for all the knowledge sharing!

[@complimentary_voucher]

Thank you so much for doing these, nothing beats putting geology in its actual physical context when it comes to understanding the whole systems. NZ is so underserved in this respect.

[@OutThereLearning]

Thank you for your appreciation.

[@sixthsenseamelia4695]

I didn't even know this place existed until now. The landscape is utterly spectacular. These videos explaining the geology & history of lesser known areas has re-invigorated my interest in exploring New Zealand. I love Out There Learning Channel. 💝

[@OutThereLearning]

Thank you, that's really great!

[@StuffandThings_]

Man, NZ has so much underrated geology beyond just the tourist traps. The old eroded volcanoes of Northland in particular seem to get completely left out. I didn't even know about this one but the setting looks absolutely stunning, definitely one to visit some day. Maybe you should do a thing on Whangaroa next, an old eroded volcanic field that has been intruded by the sea. In my opinion, its one of the best ria systems in the world that don't involve any tectonic subsidence (The Marlborough sounds and the Musandam peninsula are rather unbeatable otherwise), its crazy that pure water erosion created something which almost looks like a miniature fjord system.

[@OutThereLearning]

Thanks for your comment and suggestion!

[@1998TDM]

+1 Whangaroa is amazing. I have indelible memories of leaving the harbour on glass calm water, blue / purple sky at dawn and cascades of mist running down the cliff faces. Absolute life moment. To be fair, NZ is really good at life moments. I believe the Bay of Islands, home, is volcanic, too.

[@StuffandThings_]

@@1998TDM Bay of Islands has some remnant bits of volcanic rock from the Kaikohe-Bay of Islands volcanic field, but near the ocean its surprisingly sparse. The inlets are pretty much just greywacke. Still a really nice ria system.

[@morganlefey]

Another erudite video. Your clear delivery definitely holds my attention. Thanks!

[@OutThereLearning]

Great!

[@gaius_enceladus]

Wonderful video! I love finding out about the more obscure volcanoes in New Zealand! A suggestion - maybe you can do a video on Karioi and Pirongia - that would be great! Oh, and Mt Somers in Canterbury too.

[@OutThereLearning]

Thank you!

[@mikebarton]

We found them last Christmas. Lovely views. So good to watch this and understand the history/geology. Thanks for posting. 👏 👏👏

[@OutThereLearning]

Great!

[@orangespy]

[@scottyfrognsock2396]

Have climbed both of these, Quite a few years ago now actually abseiled Maungaraho on a school trip

[@mollyn03]

This is so exciting - I grew up in this area & I knew that these landmarks were volcanic, but I had no idea that they were linked in this way or that they were vents, rather than volcanic cores in their own right. Thank you for this, it's both humbling and thrilling to learn more about a place I know so well.

[@donhargrave5376]

We've climbed Tokatoka a few times over the years on our way to/from Dargaville. It's very small at the top! Wonderful views and you can wave to the cars on SH12 - sometimes they wave back!

[@plumchutney_enzed]

Love it! Thank you for scaling the heights and making this video, fascinating. Another location you've shown us that is now added to my list of places to see 😂

[@OutThereLearning]

Glad you enjoyed it!

[@jexiagalleta]

Make sure you do Kai Iwi Lakes and Pouto Lighthouse!

[@ashcustomworks]

Your drone shots are just magnificent.

[@mikeraphone785]

Really interesting but it would be great if you could overlay a visual of the volcano for those of us with no imagination :)

[@gasdive]

Thanks for these videos! Is there somewhere currently that is similar to how this place would have been 18-19 million years ago?

[@BruceHayward1]

About the same size as Mt Pirongia, which is a little eroded now.

[@keepitkiwi]

I remember climbing this as a kid, fascinating history. A beautiful place to visit is Taupo Bay, interesting topography and there's some conglomerate rocks on the southern end of the beach.

[@DeliciaNZ]

Great video, the climb up Tokatoka is steep but doesnt take long to get up there for an amazing view.

[@jorothbaum4114]

Love these clips, learning about the land. Thank you.

[@rod-contracts1616]

Definitely worth a visit and hike to the top. Lovely bush around it too.

[@DrewWithington]

What a fantastic piece of teaching.

[@OutThereLearning]

Many thanks!

[@DrewWithington]

@@OutThereLearning No really. I don't know your background. But I have a geography degree and know enough volcanology and you explained what happened really well. And loved the drone shots.

[@theunknownunknowns256]

Why does the North Island have so many eroded volcanoes? When the South Island seems to sustain uplift, less connected materials like bedrock? We need weta workshop to animate every known geological process in Aotearoa's past.

[@MrWombatty]

Because of the fact that the North & South Islands of NZ have formed by the different way the two continental-plates collided on either side of Cook Strait, those North Island's eroded volcanoes & the land surrounding them are aeons older than the Southern Alps (or those on the active faults down the middle of the North Island), with much of the Auckland region also being very old! Here in Australia there's also some very old eroded volcanoes which have left little but the cores remaining, with these areas scattered all along the Great Dividing Range (including some parts of Tasmania)!

[@kentaylor2416]

​@@MrWombattyI didn't know that Australia had volcanoes until I went past Mount Elephant.

[@theunknownunknowns256]

​@@MrWombattyI couldn't find a definition of "eon" after moments of checking so I gave up. I do believe north and south islands are roughly similar at atmospheric exposure to erosion. Seems OTL might need to dumb things down a little for some of us.

[@MrWombatty]

@@kentaylor2416 Mount Elephant? There isn't any mountain named that, but there's a Mt Dromedary (locals now prefer its indigenous name, which i can't remember just now), which Capt. Cook named as it looked like a camel (its head is actually a smaller separate extinct volcano). Montague Island off the coast there near Narooma, actually originated from the same magmatic hotspot!

Thanks for your appreciative comment

[@ToyneHarris]

And just across on the other side of the river there was also a small mound of very hard basalt, which became a quarry and has now pretty much disappeared. It was important because the other (western) side of the river is just sand, and there were no other rock sources in the area.

[@shortaybrown]

New Zealand : Like Scotland, but further.

[@OutThereLearning]

Och aye!

[@BeachcomberNZ]

Reminds me a bit of Mt Paku, in Tairua. Don't know if you've checked Paku out, but if you haven't, it might be worth a look.

The Northern Wairoa river comes from the Hikurangi swamp many miles upstream 👍

[@neilmarshall5087]

Would the round spot in the river be an old meteor strike?

[@OutThereLearning]

Looks like it, but no evidence of such an event having happened there (such as debris fallout, crater rim etc)

@@OutThereLearning ??? So the mountain overhead can vanish into the sands of time - but a crater cannot lose its lip.... Lol. I do get the date difference. I just saw the funny side in your answer...... Thanks for the response.

[@bobkoroua]

Bonkers. Time is the most powerful dimension then.

[@OutThereLearning]

Indeed! Appreciation of vast amounts of time is one of the things that comes from detailed geological investigations.

[@fredio54]

Neat! Is this part of, separate to, or in some non-pacific-ring way related to the Whangarei volcanic field?

[@BruceHayward1]

It is andesitic in composition and therefore one of a number of volcanoes in the Early Miocene (22-16 million year old Northland-Auckland Volcanic Arc above the plate boundary subduction zone at that time. This arc includes the Whangarei Heads Volcano/es. The young basalt Whangarei Volcanic Field is an intra-plate field of small eruptions similar to that of the young Kaikohe-Bay of Islands, Auckland and South Auckland fields and NOT directly related to the plate boundary = Pacific ring of fire.

[@fredio54]

@@BruceHayward1 Thanks Bruce, it's an absolute honour to have a response from you directly - and an opportunity to let you know how awesome I think you are. One of a kind, for sure. After your lake Pupuke piece on this channel I stopped to "smell the flowers"/ look at the rocks and saw all of the detail you showed - fascinating. Through most of my life I've taken all of this stuff for granted with the obvious exceptions. This channel is turning that around and it's your authoritative and articulate speaking that has done the trick. Thank you.

[@Stevie671]

I want to know why the Northland West Coast is straight, compared to the indentations of the East. I've passed these core outcrops and been fascinated. Is there a proper pathway to the top? Thanks.

[@BruceHayward1]

Yes there is a formed steep track off Tokatoka Rd labelled Tokatoka Lookout Track. Anyone reasonably fit can get up there but there are vertical dropoffs at the top. The straight west coast of Northland is explained in one of the next videos -essentially a result of the large eruptions in the centre of the North Island over the past 1.6 million years combined with an earlier general uplift of Northland and Auckland in the east and down tilt to the west.

[@Stevie671]

@@BruceHayward1 Thanks! When I first set eyes upon the outcrops from the hills above Ruawai I was reminded of the Sugar Loaf mountains in Queensland. Love to know how it will look in another two million years!
