I want to note that a similar shield volcano with explosive eruptions, Medicine Lake in California, also contains a pure obsidian lava flow. Around the same period of time, both it and Newberry produced highly explosive eruptions that resulted in abundant obsidian deposits. Also; nomenclature. The flow isn’t 100% obsidian. It contains an abundance of pumice as well as well at some other pyroclastic material.
You got me to head down the Wikipedia rabbit holes after seeing this video. Apparently within the Newberry Volcano National Monument there is a place called Lava River Cave. The cave is the longest lava tube in Oregon: just over a mile long. Visitors can hike through the entire cave.
Super cool. I’ve been to the cave a few times the first time I went was actually on a school field trip. There are actually quite a few areas around the Newberry site
Lava river cave, some ice caves, an area of tree casts, cinder butes, lava fields and some water falls all make this a premier spot for those interested in geology.
@@callsignmohas5190 When we went there on a field trip we went to Lava Lands and our guide on the lava trail was blind. Let me say that again. Our guide was blind.
@@timothyball3144 Well once the flashlights get turned off I think everyone becomes blind lol. What year did you go? We went on a field trip when I was going to the Oregon youth challenge program just outside of Bend in 05
Found out about this from Nick Zentner, a geologist from University of Central Washington. He does a lot of videos about the geology of the Pacific Northwest. Good job on this video and channel.
Another amazing obsidian feature in central Oregon is Glass Mountain. I had the immense pleasure of rockhounding there for a couple of days. Snowflake, rainbow, gold sheen, mahogany it's all to be found there. Amazing.
UA-cam algorithm snooping on me? Was just outside polishing a piece I collected from Glass Butte. Bit of shaping at 50/100 and then 200 to start smoothing. Cleaned it up and took it into the sun to get a good look -- mahogany with a black stripe in the middle. Gold sheen showing in part of the mahogany and the black has a good layer of tranclucent on top with baby snowflakes forming and suspended in the clear. Looked like a small piece of plain mahogany before I started. Never underestimate your raw material. Came inside and this video was being recommended.
Crater Lake was believed to be a holy place by Native Americans, and they kept it secret from the settlers. I don't remember anything about Newberry, but you have to see it in person to grasp the effect it has on people.
I've been to this spot. It's incredible how tall the obsidian flow really is. Several stories tall. A note to those who may want to visit....fall or spring are best. The hot midsummer sun reflecting off the obsidian makes it an very hot endeavor.
@Be Holy The vast majority of gemstones originate deep in the crust from magma that takes an unusually long time to cool, thus forming large crystals. Of course, some rhyolite lavas just naturally contain an abundance of topaz and garnet.
@Be Holy Topaz Mountain in Utah, and a few scattered extinct volcanoes in northwest New Mexico. Topazes are surprisingly common, just crystals large and transparent enough for use in jewelry ARE rare
Ya really, I used to look for small pieces from the abandoned ancient Rio Grande channel gravels to make points from and get excited to find one more than 2 inches long
The obsidian there isn't anything special other than the quantity, but nearby is glass butte, with mahogany obsidian and even some rainbow obsidian, and you can dig for free. BLM.
Thanks for a tour of this unique geological feature …! Oregon really has some varied Topography…would the Columbia River Basalt Group be worthy of an episode or two …?
@@GeologyHub Great thanks…. I vacationed in Hood River once … and Kiteboarding on the Columbia with those Basaltic cliffs in the background was definitely an Experience that I won’t ever forget …. The Drive from Yellowstone to the Columbia Gorge across the Basaltic Fields is worthy of a scientific pilgrimage….
@@Primalxbeast It's better than flint .. because it doesn't have the impurities that flint can have. So it's edges can be much finer and slice like a razor blade
This particular flow is within a protected area, so no modern knappers get to use it. However, there is a much older source not too far south, at Glass Butte, where you can collect for non commercial use. I believe there are also some Dacite flows where you could collect knappable stone.
@@ValeriePallaoro u can't say obsidian is better than flint tbh, flint is harder and you are most likely to get what you want if you knap quality, pure flints by removing the outer nodules. Obsidian is fragile, takes a mastery to knap even a simplest piece. One mistake which you'll probably make ends the piece. Therefore even if you strike the edges only, it's most likely going to break from half at some point.
I just visited this place in July! It's a pretty amazing thing, and the more so because it's so easy to get to - at least if you're already in the area. The obsidian is so crazy abundant that some of the walkways and stone walls at the trailhead area are built out of it.
I've hiked on the Big Obsidian Lava Flow. It's so big and amazing to see. Since Newberry is the second most seismically active volcanoes in Oregon, I wouldn't be surprised if it erupts within the next 50 years.
I've visited Newberry Crater a few times. Good fishing in the lakes, and the geology is stunning. There is another large obsidian formation about 95 miles NW of Newberry crater, the Obsidian Cliffs. This is a large cliff face that varies between pure obsidian and obsidian with rock impurities. My parents carried out a few small boulders before that became illegal. The cliffs are below the west side of the South Sister, off of Sunshine Meadow, at the top of the Obsidian Trail. The Pacific Crest Trail runs through Sunshine Meadows. I practically grew up in the area, visiting the high Cascades several time every summer, before restrictions on visitors grew too great, in the late '90's.
If you go outside the monument on the backside there’s good fragments that you can take home for souvenirs and not get arrested. Also while you are here, don’t forget to take the Paulina plunge, and please, please, please I’m begging. Pack out more than you brought! From a local that grew up here, it’s getting so trashed from people that sat “I love it” but don’t actually care. It’s happening so much over the entire region and sad to watch.
@White Raptor News I have some cool aid for you to drink. Maybe ride a comet and play with aliens. No news of trumpertantrum? Lmaooooo! What about the news of all the priests touching kids? This is the people that preach your good word to you! Preaching hypocrisy. No matter what left/right porpoganda you listen to and believe. Religion is one of the roots or hypocrisy. Remember, first to preach and you DAMN WELL ARE the very first to persecute, always throwing your “mighty” finger around. What a joke.
I found a perfectly round obsidian ball here in Idaho upon coming back home after many years of being gone! It wax the first day after my arrival. It’s an amazing ball:)
The lakes nearby have rocks floating in them from the pumice. You can pick up a big looking bolder that only weighs a few pounds. It's almost like you're walking on the moon on the top of that flow. Definitely worth a visit if you're in the area.
I was just there a few months ago, there's stairs that go up 70 feet to be on the top...Im too outta shape to walk it so I plan on it next year...its absolutely beautiful
I visited this area recently. There are paths and stairs to access the to of this feature. It's like being on a different planet. One thing video cannot convey is the smell. I can't describe it but it's definitely odd.
If I'm not mistaken, this is what happened near Picketpost Mountain in AZ, and it slowly cracked and eroded away into Perlite with small surviving central nodules of obsidian we call Apache Tears. I love gathering these.
There are small obsidian boulders scattered all over the desert around Las Vegas. They're the best quality I've ever seen. They're very dark and very clear, most with zero striations.
You should really check out the Three Sisters complex near Bend, Or. In addition to the sisters there are two more sets of three volcanos of successively greater ages and states of erosion. The best parts are only accessible by days of hiking but are spectacular and well worth the effort. There are enormous cliffs of snowflake obsidian with thousands of years of napping wast a half hour walk from the north entry.
In the 80's my mother used a ceramic kiln to melt samples of ash from Mt. St. Helens that were collected at various distances from the volcano. First she slip cast some thick porcelain crucibles in a small and beaten up flowerpot mold and fired them. Then the pots were filled with the various ash samples. All but one just sintered into solids like a grindstone. The one that didn't do that melted into a dark ruby red glass. Don't know where that ash sample came from. If the source could be located and if it'd still melt the same after 40+ years, it would be an amazing material for glass artists.
There are some super impressive chunks of obsidian in the pumice fields just south of Mono Lake in California, super unique forest area to camp in too. Old growth pine forest right in the middle of a pumice field limits the undergrowth quite a bit so its super fun to hike around.
Amazing, near Christchurch in New Zealand on Banks Peninsula which is the eroded flanks and remains of a basaltic lava dome volcano there is a large blob of obsidian outcropping from the layers of basalt and scoria, hiking to it was part of the field work i did when completing my undergrad geology degree many years ago, the geological setting seems very similar to the video, just way way smaller.
Love it! So much info!! My brain is so excited! Can you show us some examples of rocks that you personally own? I bet you have access to some amazing finds.
Been there, Newberry is an incredibly interesting place. The black obsidian does tend to get quite hot in the sun though. There's an old no longer maintained trail that runs between the two large lakes, between the cinder cone and the T-shaped lava flow to the north that is incredibly neat. Definitely a place worth checking out, along with all the other unique geologic features of Oregon.
@@bob_frazier Wait there are hot springs at the end? I just knew that it led to the part where the lava flow spills into one of the lakes which is pretty cool.
@@StuffandThings_ The hot springs are on the north edge of Paulina lake, and just about at lake level. They are not super spectacular, but a fun place to go.
@@bob_frazier Oh, I was talking about a trail that runs between Paulina and East lake, along the lobe of the lava flow. It is a *very* obscure trail but incredibly neat. The hot springs might be worth checking out though, the PNW is weirdly lacking in good hot springs despite being very volcanically active
I guess Oregon must be the best place on earth to find obcidian. If not where is the best place to find it? I Know that it's the only place where green and certain fire obcidians are found! I can think of at least 8 places that have massive deposits in Oregon. Defiantly Still my favorite knapping material!
In the N.M. Jemez mountains along the Jemez river are tons of beautiful, clear, blemish free obsidian chips. The indians made weapons/ tools out of it. Razor sharp edges one could shave with. Never thought of them as "jewells" before but have never seen clearer obsidian anywhere else & N.M. is a geologic wonderland.
I agree that New Mexico is a geologic wonderland. I grew up in Albuquerque and collected beautiful rocks. Obsidian being one of my favorite. (I also created a little home for horny toads that became my pets.) Good memories and now I binge watch geology videos with this one being at the top of my list.
This seems beyond comprehension. There are deposits of obsidian in the Jemez Mountains of New Mexico where I grew up, but they are widely disbursed. My father even knew of a deposit of brown obsidian. He patrolled the perimeter of the Los Alamos National Laboratory facilities as part of his job, and that is how he discovered the deposit. Apparently the infusion of smoke into the molten obsidian is how the brown coloration occurs.
I can't imagine how much time it takes to put one of these videos together. Do you have a staff or is it all the work of one person? Either way, it's great. Thanks from Florida.
How does Obsidian form? I too am puzzled by the lava flows (I'm pretty sure "Mountains of the Moon" in Idaho also has a Lava flow). The obsidian I'm most familiar with, from the Aeolian Islands of Italy, was formed by the compression of hot (melting temperature) ash which was compressed by the weight of the material that covered it. In essence, the gas was forced out and the ash was compressed and heated into a glass. (I've got some Aeolian obsidian samples, and would LOVE to get some samples of western sources of obsidian!) Source of information - my mentor who specialized in Obsidian sourcing and trade. What this suggests to me is that the amount of gas (or steam) had been removed from the molten material, and then something cooled it down rather quickly. BTW - using elemental analysis (XRF or others), it is possible to determine the source of material (such as Obsidian) even into an individual flow from a volcano, which helps to determine trade routes and forms of exchange. I would be very interested in a trace element analysis of the obsidian from those (and other) flows.
You can drive to the top of Paulina's peak and it's an amazing view. On a clear day you can see Mt. Shasta in California & Mt. Rainier in Washington, and all the cascades in between.
The video mentions that this flow is inside the caldera. My guess is that there was a crater lake when this flow was created, and flowing into the water is what cooled it quickly enough to form into obsidian.
I live about as far away from this site as one could imagine (southern Ontario, Canada) BUT for several days, quite a few years ago, my hiking boots clomped all over the Newberry Volcano. Walking in certain areas sounded like I was walking on broken glass (sorry, Eurythmics!...)...which, of course, I was!
Lets just say that Im a collector of many stones for their medicinal properties. I juat may have to visit this spot because black obsidian is one of my favorites.
Ohh I missed this video I remember looking this up after Nick Zentner visited it and found a paper discussing its magmatic source and finding it is actually fueled by a mix of both Cascade and Basin and Range magmas. That Basin and range basaltic magma probably helps explain the overall shield component with the more silica rich magma coming later off of the cascades.
Once you are done at the obsidian flow, walk across the main road and scout around for the big crack. I don't know if its marked or not, but its kinda fun as well.
@@timothyball3144 Sadly, no stone left unturned. With social media and geotagging. Not even Klondike Kates old campsites are sacred anymore. Green lakes trail area is more like green lakes highway. I don’t even go out there anymore. I go way farther East now a days, but even then, it’s hard to actually get away.
Does obsidian means the magma flow directly from the deep source fast and cooled fast too? Because it skip all the probable magma process such as differentiation, mixing, mingling, or and assimilation
How did it cool quickly, and if it did cool quickly, how did it manage to spread out in a more or less flat pattern that looks like it was liquid? How can an eruption cool quickly and still take several years to spread out?
I don't understand how this entire lava flow cooled in just a few minutes. In a previous video you said that a single large lava bomb would take several weeks to cool. ua-cam.com/video/YTJAQ9EbyI0/v-deo.html I would be very interested to watch a video explaining lava cooling rates as it sounds like there is a lot of non-intuitive stuff going on, and that cooling is important to the properties of the resulting rock.
Its right at the start of the little ice age, most of Washington and northern Oregon would have had glaciers at that point so you could be on to something there.
In the neolothic age was Obsidian the best working material. Obsidian of Lipari was exported on the whole Mediterranian Sea. It was the wealth of that island. I think the first nations will have estimated it too.
I want to note that a similar shield volcano with explosive eruptions, Medicine Lake in California, also contains a pure obsidian lava flow. Around the same period of time, both it and Newberry produced highly explosive eruptions that resulted in abundant obsidian deposits.
Also; nomenclature. The flow isn’t 100% obsidian. It contains an abundance of pumice as well as well at some other pyroclastic material.
Thank you for doing another video on the Newberry Volcano.
What caused it to cool in a matter of minutes? The video doesn't really say. Thanks
So cool! I love in Oregon I can't wait to check this spot out
You're the best, thank you for this
@@Eric_Hutton.1980 he's given us so much attention and videos, makes Oregonians blush
This obsidian was prized by the first humans in the NW. Cutting tools made from it have been found from Alaska to California!
Came here to post this - thanks!
Even at the great lakes area have they found obsidian from this area 4000km away. It greatly changed the ideas on Palaeolithic trade.
It has also been used by modern surgeons for its fine edge.

Wow! This place must have been very significant to the people of the region. I wonder how it fit into their lore?

@@GeologyHub damn way ahead! Nice!
Obsidian is rather common in the northwest.
@Be Holy The vast majority of gemstones originate deep in the crust from magma that takes an unusually long time to cool, thus forming large crystals. Of course, some rhyolite lavas just naturally contain an abundance of topaz and garnet.

As a flint knapper constantly on the lookout for decent material this site would be a dream come true.
You're not supposed to remove any of the obsidian, but I somehow, um, accidentally came away with a couple small pieces.
Ya really, I used to look for small pieces from the abandoned ancient Rio Grande channel gravels to make points from and get excited to find one more than 2 inches long

A lot of flint knapper's would be glad to get that. Obsidian makes beautiful arrowheads and can be sharpened like a razor.

In the N.M. Jemez mountains along the Jemez river are tons of beautiful, clear, blemish free obsidian chips. The indians made weapons/ tools out of it. Razor sharp edges one could shave with. Never thought of them as "jewells" before but have never seen clearer obsidian anywhere else & N.M. is a geologic wonderland.
I agree that New Mexico is a geologic wonderland. I grew up in Albuquerque and collected beautiful rocks. Obsidian being one of my favorite. (I also created a little home for horny toads that became my pets.) Good memories and now I binge watch geology videos with this one being at the top of my list.
Excellent and informative vid
Amazing! I should head over there some weekend.
This seems beyond comprehension. There are deposits of obsidian in the Jemez Mountains of New Mexico where I grew up, but they are widely disbursed. My father even knew of a deposit of brown obsidian. He patrolled the perimeter of the Los Alamos National Laboratory facilities as part of his job, and that is how he discovered the deposit. Apparently the infusion of smoke into the molten obsidian is how the brown coloration occurs.
I can't imagine how much time it takes to put one of these videos together. Do you have a staff or is it all the work of one person? Either way, it's great. Thanks from Florida.
How does Obsidian form? I too am puzzled by the lava flows (I'm pretty sure "Mountains of the Moon" in Idaho also has a Lava flow). The obsidian I'm most familiar with, from the Aeolian Islands of Italy, was formed by the compression of hot (melting temperature) ash which was compressed by the weight of the material that covered it. In essence, the gas was forced out and the ash was compressed and heated into a glass. (I've got some Aeolian obsidian samples, and would LOVE to get some samples of western sources of obsidian!) Source of information - my mentor who specialized in Obsidian sourcing and trade.
What this suggests to me is that the amount of gas (or steam) had been removed from the molten material, and then something cooled it down rather quickly. BTW - using elemental analysis (XRF or others), it is possible to determine the source of material (such as Obsidian) even into an individual flow from a volcano, which helps to determine trade routes and forms of exchange. I would be very interested in a trace element analysis of the obsidian from those (and other) flows.
Would love a video on the Pink and White Terraces in New Zealand.
Looks to be a particularly difficult material for vegetation to colonise.
Great video. I kayak East Lake during the summer. Quite spectacular.
Would've been a great place for someone making obsidian tools in the prehistory
I love geography about my home area of central oregon
You can drive to the top of Paulina's peak and it's an amazing view. On a clear day you can see Mt. Shasta in California & Mt. Rainier in Washington, and all the cascades in between.
Thank you. Was very informative. Keep making these types of videos.
God bless
Was just here about 1 month ago, it's a spectacular place to visit.
I’ve been there! It’s just magnificent!
Been there. I love this place! So neat to hike up around the flow.
How interesting. So pretty. It's so cool how such beauty can come from such a scary occurence.
Love the videos! Would love seeing you cover seafloor lava vents/ fissures in a future video if at all possible. Thanks for the consideration.
Hey dude so yeah i watched ur content for 1 year now but i like ur content
Me again. Living in guatemala born in Oregon. This was fantastic! Must have been pretty cold weather I’d think.
The video mentions that this flow is inside the caldera. My guess is that there was a crater lake when this flow was created, and flowing into the water is what cooled it quickly enough to form into obsidian.
I live about as far away from this site as one could imagine (southern Ontario, Canada) BUT for several days, quite a few years ago, my hiking boots clomped all over the Newberry Volcano. Walking in certain areas sounded like I was walking on broken glass (sorry, Eurythmics!...)...which, of course, I was!
To watch that flow would have been unbelievable
Love the break down and a lot of cool history my only criticism is that Obsidian is a Glass due to its Lack of crystalline structure.
Also in Oregon,
Could you discuss Smith Rock?
I've been to Medicine Lake's Glass Mountain, but haven't been to Newberry yet, Some day soon I hope as I live right between the two.
Such a beautiful place! I've been there twice in my life!
Lets just say that Im a collector of many stones for their medicinal properties. I juat may have to visit this spot because black obsidian is one of my favorites.
Semi-precious gemstone? Ha ha ha. I have about 10 tons of obsidian spread around my home for landscaping. It is a beautiful stone.
Ohh I missed this video I remember looking this up after Nick Zentner visited it and found a paper discussing its magmatic source and finding it is actually fueled by a mix of both Cascade and Basin and Range magmas. That Basin and range basaltic magma probably helps explain the overall shield component with the more silica rich magma coming later off of the cascades.
1 minute in and I'm hooked!
Yes enjoyed this very much thank you!😊👏👏👏👏👏
Amazing many thanks for posting..
Beautiful obsidian in those parts
A fast and slow running magma tap. Who'd've thought? That's a heck of a plumbing system.
Once you are done at the obsidian flow, walk across the main road and scout around for the big crack. I don't know if its marked or not, but its kinda fun as well.
It’s been beaten out and worn in enough. It’s pretty easy to find. Sadly follow the human impact right to it.
@@timmymccheee7213 That bad, eh? Surely there are less impacted areas?
@@timothyball3144 Sadly, no stone left unturned. With social media and geotagging. Not even Klondike Kates old campsites are sacred anymore. Green lakes trail area is more like green lakes highway. I don’t even go out there anymore. I go way farther East now a days, but even then, it’s hard to actually get away.
Does obsidian means the magma flow directly from the deep source fast and cooled fast too? Because it skip all the probable magma process such as differentiation, mixing, mingling, or and assimilation
Perhaps,the gases created a pressure difference at the local summits,which made it rain on the flow,creating extended obsidian fronts
How did it cool quickly, and if it did cool quickly, how did it manage to spread out in a more or less flat pattern that looks like it was liquid? How can an eruption cool quickly and still take several years to spread out?
it must be caused by a speedrunner trying to learn how to make a portal without a diamond pick.
Lol
I don't understand how this entire lava flow cooled in just a few minutes. In a previous video you said that a single large lava bomb would take several weeks to cool. ua-cam.com/video/YTJAQ9EbyI0/v-deo.html I would be very interested to watch a video explaining lava cooling rates as it sounds like there is a lot of non-intuitive stuff going on, and that cooling is important to the properties of the resulting rock.
Its right at the start of the little ice age, most of Washington and northern Oregon would have had glaciers at that point so you could be on to something there.
Fyi, when basalt is quenched quickly it forms tachylite, not obsidian! Obsidian is rhyolite composition glass, not basalt.
It's beautiful
It was very informative.
In the neolothic age was Obsidian the best working material. Obsidian of Lipari was exported on the whole Mediterranian Sea. It was the wealth of that island. I think the first nations will have estimated it too.
thank you for the video and I love your videos
I always forget that there's lava flows so close to me - usually until I'm looking at a map and notice one. Maybe next summer needs a road trip.
Great video thank you 👍🏻
Beautiful, thank you!
