Why Crater Lake is So Deep
ฝัง
- เผยแพร่เมื่อ 12 มิ.ย. 2022
- Crater Lake, Oregon. The Deepest Lake in the United States. Some of the cleanest water in the world. Crater Lake National Park is one of the oldest in America and attracts hundreds of thousands of visitors each year to its beautiful, cerulean waters. But, what created Crater Lake? Well, a massive volcano. The Crater Lake Volcano Eruption was one of the most powerful eruptions in the world in the past 12,000 years and is the primary reason why Crater Lake is so deep. I hope you’ll join me on this geological journey to find out how Crater Lake formed and how that violent, chaotic history informs how Crater Lake operates today. Enjoy!

Hey folks: getting lots of comments on how the fish got into Crater Lake, despite having no inlets or outlets. The short answer: it was stocked. Starting in the late nineteenth century, Crater Lake was stocked with 7 different species of fish, 2 of which thrive in the Lake today: Kokanee Salmon and Rainbow Trout.
Climate change hoax got a dislike and an unsubscribe
Birds bring fish eggs in their shit too..lol😅
I'm not even sure how to verify this, but a Klamath woman in central Oregon told me that the story of this eruption had been passed down throughout the ages by the Indigenous tribes of the region because it was like an apocalyptic-level event.
As the event was around 7000-8000 years ago, it would be highly unlikely. However oral histories can potentially last that long, in theory
@@robrod7120 I am a citizen of the Choctaw Nation. Our homelands are in the southeast of the US; we have oral stories about wooly mammoth/mastodon, in particular relating to their sudden mass-death due to disease. Current estimates place wooly mammoth and mastodon as having gone extinct at least 11,000 years ago. Indigenous Nations have very long memories, especially of cataclysmic events.
@@Mockingbird_Taloa I applaud those who keep oral memories and "stories" alive. I consider them far more reliable than other sources, especially when those sources keep arguing among themselves as to what they think is correct. Oral histories are consistent.
@@robrod7120 “No Native American group in the state of Oregon maintained a written language prior to the arrival of European-Americans, nor for a considerable period thereafter.”
Wikipedia of tribes of Oregon.
They definitely would have passed this tale down orally.
Native American people have lived in the area near Mazama for at least 10,000 years.[15] At least part of the surrounding vicinity was occupied by indigenous populations when Mazama resumed activity about 8,000 years ago, following about 20,000 years of dormancy.[5] Most evidence suggests that Mazama served as a camp site, but not a permanent place of habitation.[23] Sagebrush sandals have been discovered to the east of the mountain. These populations faced an increasingly dry climate and the hazards associated with volcanic activity. In civilizations south of Mazama, stories about the volcano's eruption have been transmitted for many generations.[5] Native populations did not tell settlers about the area because it held sacred importance among tribes throughout Oregon and northern California.[23] Shamans did not allow local Native Americans to look towards Crater Lake,[26] and the Klamath people believed that just looking at Mazama would cause death. Though there are no tribal legends surrounding Crater Lake, some Native Americans still refuse to look at the water.
That is correct. If you'd like to learn more, I found this page very helpful to understand the significance of Crater Lake to the Klamath: www.craterlakeinstitute.com/smith-chronological-history-of-crater-lake/sources-and-articles-of-interest/orgin-stories-of-the-lake/
Omfg this is awesome, I'm going to Crater Lake today this is perfect timing!!
Its amazing, but watch out for the slippery rocks. Easy to fall along the rim in many places.
I went yesterday too!
Glad I could help! Enjoy your visit!
How was your trips?
YESSSS CRATER LAKE THIS IS MY PARK LETS GOOOOOO
I've swam in Giiwas's (native name, english grammer? whatever) cold clear waters. Seen her beautiful Newts, drank from the springs of her steep outer walls, and climbed the slopes of those great peaks that enclose her.
She is (without having been to THAT many National parks) without a doubt, my favorite National Park, and certainly my favorite lake.
In the last video I was going to suggest a Crater Lake video.... but, about something with a bit more specific. See theres this grey ghost that pokes his out of the crystal clear and endless blue waters. An ancient Hemlock tree, some 450 years old that has been floating, even protecting, the lake for over 100 years. He harbours mosses at the surface that are otherwise only found deep below the surface, and stands upright out of the waters no matter the weather.
The Old Man of The Lake we call him today. And he is as much the spirit of Crater Lake as any lake could hope to have.
I read about that in my research! Honestly, looking back, he should have gotten a shoutout in the video lol. But, glad you liked the video and glad I could spotlight your home park! Thanks for watching!
The whole world was once tropical some 6° warmer than today the ocean level was some 400 feet higher than today its a natural cycle
I live in Oregon and have likely visited Crater Lake over 15 times. I congratulate for making a video about Crater Lake that is so indepth rather than the shallow videos of a one-day visitor.
No problem, that's something I always strive to do on this channel, no matter which park I'm covering. I'm a little jealous you can visit Crater Lake so frequently though! Thanks for watching!
Same
i grew up in Klamath County. Crater Lake was in my back yard so to speak. It's amazingly beautiful any time of year. Like everything else, pictures just don't do it justice !:-)
💜🙏⚡️
How lucky you are to have this place in your backyard!
Crater Lake is so massive it's quite overwhelming to stand on the rim. Such a pretty place.
Thank you so much for putting these stories out I’d love to see some more topics on some indigenous Native American groups that resided in national parks ! Keep up the great work man !
Fun fact: Rocky Mountain National Park's Trail Ridge Road follows the path the Ute's took between the Estes Park and Grand Lake area for thousands of years!
@@coloradohikertrash9958 thats super cool I never knew that. I've lived in Boulder my whole life.
Would love to listen to those
Absolutely, thank you for watching them! And noted. I try and incorporate Native histories and cultures as much as I can in these videos - they're a crucial part of any park story and deserve to be told.
@@NationalParkDiaries Oo would be looking forward to that, love your videos man 🤝🏻
I knew a little information about Crater Lake, but your video added more to my knowledge.
Glad I could help Joe!
Thank you so much for this video 🙏 crater lake is now added to my bucket list of places to visit thanks to you! I have to witness it’s beauty before it’s changed to much 👌
Thanks for watching, good luck on your travels!
Thank you for including the Indigenous history of what is now Crater Lake NP! Our histories are so often overlooked or minimized--there is nowhere on Turtle Island that is important to people now that hasn't always been important to us.
Absolutely. I think that's a vital piece of this story and you can't talk about the story of the National Park without it. Thanks for watching.
As a Caucasian born in America, it irritates me when Americans go on and on about their freedoms being in jeopardy, even in cases when it is not. The real freedom of this country was ruined when white men came and discriminated the natives and pushed them out of their homes. Your histories should not be forgotten.
"The depth is proportional to the size of the caldera"
I would actually guess the caldera was much deeper. Subsequent eruptions and erosion have likely made it much shallower than it originally was.
Near by Crater Lake is the Metolius River that is a full size river that flows up out of the ground, I know I fished it and camped on it 40 years ago, check it out
Awesome video as always. Thank you
Thanks for watching!
The music that started when you explained the creation of the lake was just *chefs kiss*
I like your illustrations bro. Especially the witch from OZ melting and Ash Ketcham from Pokémon. Good stuff
Haha, thanks! Gotta keep it fun!
Great video I have always wondered if Crater lake was leaking.
Thank you and same! I was so curious about that lol
Great channel, thank you!
Thank you for watching!
So happy to see your new video in my feed. Another excellent video. Well done
Thanks for watching!
I asked for a volcanic park, and you delivered! Well done on a truly classic cascade volcano....
It's like a window into what Ranier or Adams or Hood will look like in 1-3 million years. Baker is far enough north it often sees different lavas that both build and collapse faster, so each peak is younger and many more have existed in one spot.
Looking at Mazama is a great example of the opposite, "old-ish" caldera version of cascadian volcanoes.
Haha, yep! I started reading about it and I got to "giant volcanic explosion" and was like "say less." Honestly though, it is a really cool geologic story and I like the contrast of the violence of the explosion with the peace and tranquility of modern Crater Lake.
@@NationalParkDiaries I just got back from a camping trip where we hit several spots in OR and WA. You might find Crack in the Ground and Fort Rock worth looking into. Oh, and Beacon Rock in WA has an interesting story.
Excellent, thank you for putting this info together.
Thanks for watching!
Remember what happened to My. St. Helens was similar but on a much smaller scale.
I wasn't alive yet to remember it lol. But, looking at footage and the various studies that have come out about it, I thought it would make a good comparison for just how gigantic the Crater Lake eruption was.
I don’t know if you’ve thought about doing any kind of collaborations, but if you were to do a video with Atlas Pro, I think it’d work really well. His videos have a very similar vibe to this one, and I think there’d be some good audience crossover. Just a thought.
That's good to know, thanks for the suggestion!
LOVE the channel!
I'm glad! Thanks for being here!
In my trip in 1995 to Alaska saw in the yukon the pumus from an volcano explosion who knows how many thousands years ago. Mt. Saint Helens pumus embedded in trees 20 miles away from the explosion. Upon crater lake dont remember miles away from the lake there are giant boulders and pumus before getting near the park. Nature works wonders
How did the fish's get there? Maybe not the best place for them anyway since any slight change from the volcano, sulfur, temperature etc will kill everything
Great job!
Thanks Brian!!
*THANK YOU* for giving the real-world explanation of how much ash was ejected - imagine 6.5” of ash covering the entire state of Oregon. Now *that* is apocalyptic!
Would be great if you’d give us “Granolas” in CA an idea of how much ash would be generated by another one of “God’s Farts” 😉 in our local super volcano at Mammoth Lakes. (The Yellowstone eruptions get all the press coverage. 🤬)
Will look into supporting your channel-between jobs at the moment; however, like the others I support (3 or 4), you give enough depth and breadth to your topic, by relating it to the world at large that it piques my interest in learning more. You remind me of one of my best teachers ever, in a “Geology 101” course that I took via the University of MD offerings for the Army, while stationed in the ROK.
*Keep up the good work* 👍👍👍👍👍
Thanks for watching, glad you liked it! I appreciate your support of the channel in whatever form that takes. Commenting and subscribing help the channel immensely and I'm just glad you've enjoyed everything enough to stick around. It's truly appreciated and I'm looking forward to sharing more park stories with you.
I just uploaded a documentary video about my trip to Crater Lake in 2020! I miss Crater Lake!
They should put like mini mini tracking devices in the water near that drain thing and see where it goes.
They've done studies with environmentally-friendly dies and haven't been able to find anything lol!
Wanted to mention that the "shast" in Shasta rhymes with Mast or Blast. It reminded me how so many people say Nuh-vah-duh instead of Nuh-vaa-duh. Just a FYI, since you make some great videos with plenty of research.
Also, weird how many trolls are in this thread.
Thanks for the correction!
Awesome video!
Thanks for watching!
So it looks like the video from the archives is Mt Saint Helens but if it is, your date is way off. That would have been May 18, 1980 not February 13, 1990. I'm pretty sure it is Mt Saint Helens because the video shows it was Sunday and the date for 1990 you have was a Tuesday. I'm wrong I'd love to know.
You are correct. Mt St Helens was 1980, but the archived video shows 1990 because that's when that clip originally aired (it was a TV news broadcast). Good eye!
@@NationalParkDiaries thanks. BTW: I like your channel and videos.
@@EdandEdGoFishingWithoutEd Thanks, I'm so glad!
ooo on the topic of lakes in oregon with "crater" in the name - have you ever considered taking a look at _little_ crater lake? i'd argue it's actually prettier than its big sibling!
I'd never heard of it, but just looked it up. It's beautiful also!
great video
Thanks!
How did you get the aerial shots? IIRC, drones arent allowed in any NPs.
Correct, they are not allowed. The aerial shots in this video are from stock footage. I got them from Storyblocks (not sponsored, just really like their service lol)
The heavy metal you play when you mention violent eruptions is hilarious 😂
How did the fish get in the lake?
Starting in the late nineteenth century, until the 1940s, Crater Lake was stocked, which is how the fish initially got in there: www.nps.gov/crla/planyourvisit/fishing.htm#:~:text=However%2C%20between%201888%20and%201941,sockeye%20salmon)%20and%20rainbow%20trout.
Interesting. I'd like to visit Crater Lake someday.
Same!
It is so beautiful! I stood there and the hair on the back of my head stood up. Amazing
This is some of my favorite shit, I’m so glad that there are people that do stuff like this
Glad you liked it, thanks for watching!
I am curious as to how fish got into the lake and how diverse they are from area lakes. I know that in places that do have rivers and otherways of getting back up the chain, such as Minnesota where we know that nearly every lake is connected to some sort of water so fish and aquatics can move up the chain.
They explained the fish thing in another video I watched last night, some guy decided it would be a perfect place for fish to be stocked, so they stocked it with fish, how they stocked it, I don't know, hope that helps a little.
The lake is more then just water it's life.
Great video very informative …what a very magnificent and mysterious place
So many people have gone missing there and not been found the majority being young men and boys
Thank you!
“Bro touch the bottom. U won’t”
I like the wicked witch and other graphics, nice!!!
Thank you!
Thank you
Thank you Joanna!
using heavy metal music while showing lava erupting was a nice touch
Haha, it was right there for the taking. I had to do it 😂
Thank you!!!!!'
Thanks for watching!
cool video m8
Thank you!
I know the video is over a year old, but there is geological evidence that Mount Mazama was showing warning signs before the 5700BC eruption.
There's evidence that Mazama began to have multiple major eruptions starting about 80,000 years ago, most likely due to its original magma chamber turning from andesite to rhyolite magma (very explosive eruptions).
About 30,000 years ago, two rhyolite lava domes formed on the north side of Mazama which indicates the volcano magma chamber is nearly all rhyolic and its building in pressure.
In 5800-5900 BC (~100 years before the climatic eruption), there was an eruption that occurred on Mazama that ejected almost 10 km^3 of material, and formed Llao Rock which sits today on the north side of the lake.
Then we have the climatic eruption in ~5783 BC, some studies suggests that this climatic eruption ejected ~178 km^3 (over 100 times more than the 1980 Saint Helens eruption).
We love crater lake
Crater lake's major eruption was rated as a 7 on the VEI, not a 6 and St Helen's a 5, not a 4.I'm assuming this is only including the DRE, which is only part of the equation. For example, Pinatubo's DRE was 5km3 whilst its total output was in around 13km3. Other than that, great video!
Maybe learn how to type first
@@DieTryingMotivation learn reading comprehension first before making your low intelligence obvious for everyone to see, you're just embarrassing yourself now. All I did was make a correction, so is criticism not allowed now? And learn to type before what? I also bet you don't have the slightest idea what I'm talking about either.
Thanks! The eruption figures were pulled from this NPS document: www.nps.gov/crla/planyourvisit/upload/Geology-508.pdf
@Alexander Turpin, no x42 is correct though.
Where did the fish come from? If Crater Lake is filled by precipitation and has no outlets, how did the fish get there in the first place?
Crater Lake was actually stocked starting in the late 1800s: www.nps.gov/crla/planyourvisit/fishing.htm#:~:text=However%2C%20between%201888%20and%201941,sockeye%20salmon)%20and%20rainbow%20trout.
Also, fun fact, there are many unexplained and anomalous disappearances of people who go to Crater lake. The original native tribes of the area say that crater lake is an evil place and holds dark spirits. No joke, they seriously say something like that.
I will never go back to Crater lake it is known for people disappearing especially children and they never find them
My friends and I camped near the edge of that lake one time in the 90s. I had one of the scariest dreams ever - there was an old woman flying over the lake and ringing a bell loudly and laughing sinisterly. Couldn't sleep after that. Beautiful place though...
That sounds... terrifying. But also beautiful. Thanks for sharing!
Another deep interesting lake is Cresent lake on the Washington peninsula. It ia actually gouged out by the glaciers to be deeper than the surrounding sea levels
hope to see this place sometime in my life
Same!
You can but the roads there are open according to the season and no one is able or allowed to walk down to the shore lines. They do have boat tours which you can enjoy.
Crater Lake is on my bucket list. Must visit. When is the best time to go? Any ideas?
Never been myself, but I think it would depend on what you want to see. I've heard it can be very beautiful in the winter with all the snowfall, but you're best bet for maximum access and activities is probably going to be after the snowmelt, so July thru September-ish?
I’ve been in July. Still had snow piled up near roads.
hi there usgs volcanologist here the Mount Mazama eruption ejected 140km3 of Rock and Ash
I actually had some trouble finding a definitive source on this! I ended up going with this one from NPS: www.nps.gov/crla/planyourvisit/upload/Geology-508.pdf
I acknowledge that one is a bit dated, but went with it because it was the best I could find at the time. Although, a recent search brought up this paper from 2020: link.springer.com/article/10.1007/s00445-020-1362-1#Sec20 which estimates an eruption volume of 176 km^3. They also talk about in there how there's a lot of uncertainty in how these things are measured in general, but if you have some resources I'd love to read more! Thanks for the input!
Here is new footage of the Lake th-cam.com/video/Y4XXjG2vvtQ/w-d-xo.html
Great video brother, i'd like to visit this place in my lifetime. It calls to me.
Thanks, I hope to visit someday myself!
I was hoping to visit crater lake, when i go to Oregon next month, but its just to far away from our route to have enough time to go see it :(
Yeah, it's kind of out of the way unless you're going to Southern Oregon.. I might be heading to Portland in October and keep trying to fit it into my trip😂
@@NationalParkDiaries Driving from San Fran to Portland and then back along the cost road, but its just that far inland its 4 hour detour just to drive to and from it. never mind spend any time there, and sadly just dont have the time.
@@TCJones I understand! So many parks to see, so little time!
You deserve more subscribers!
Haha, thank you! Any and all are welcome here! I'm focused on putting out good park stories and I think the rest will come. Thanks for being here!
@@NationalParkDiaries That's the way to be! The focus and hard work certainly shows. Thanks for making the videos!
@@jdjaneway You're very welcome, thanks for watching them!
Strata volcanoes typically don't erupt after being dormant for 7,700 years and then become active again.
Without that mixing, there would be a danger of CO2 building up like at lake Nyos.
It’s amazing how many beautiful places in this world were actually created through cataclysmic geological violence!
Creation from destruction!
I thought the rogue river originated from the side of Mt Mazama. I always thought Crater Lake had a "leak". I guess I was mistaken. There must be another underground source for the rogue river
Would you be interested in making a video about the creation of Gateway Arch (now a national park)?
Like the physical arch structure? Or how it became a National Park? If its the latter, you're in luck - I've already made that video! If it's the former, I do think that would be an interesting video actually, so thanks for the suggestion!
I'm curious if the volume of water in the crater could significantly negate the effect of the next future eruption cooling lava far faster and making the overall impact noticeably less than it would have been had the lake instead been an empty crater...
According to this USGS report - pubs.usgs.gov/fs/2002/fs092-02/#:~:text=The%20last%20known%20eruption%20at,accumulate%20on%20the%20lake%20bottom. - it says that eruptions in deeper water are less likely to be as explosive or threaten the integrity of the rim. It also says an eruption of the same magnitude that produced the caldera in the first place is unlikely due to the lack of available magma. Overall, seems like something truly catastrophic would have to happen to cause major damage. Good thought though!
@@NationalParkDiaries Thanks glad my line of thinking had some merit to it :)
Mt St Helens forced towns 300 miles away to have a state of emergency. Within 2 weeks the cloud circled the Earth. Mt Mozama was over 100 times bigger.
C’on! Don’t know where the water from Crater Lake goes? Just go down to Klamath Lake and follow that rivers feeding it to their source! The springs feeding those creeks are 30’ wide coming out of the ground and building Klamath River later on.
Are there any books relating to national parks you would recommend? I could look myself but I'm sure you've read some good ones.
Good question! Surprisingly, I read more books that are National Park-adjacent than specifically about National Parks themselves. A lot of what I read deals with conservation/environmentalism more generally, and because National Parks are sort of at the vanguard for a lot of these issues, they're mentioned pretty frequently. I do pick up official histories and things like that at thrift stores when I find them, which tend to be on the drier side, but I enjoy them because I'm me lol. I do have a couple park-specific books that I like though: Dam! Water, Power, Politics, and Preservation in Hetch Hetchy and Yosemite by John W. Simpson, Nature's Return: An Environmental History of Congaree National Park by Mark Kinzer, A Walk in the Woods by Bill Bryson (about the Appalachian Trail), and I'm currently reading about the Kentucky Cave Wars right now (by David Kem).
A few of my park-adjacent favorites are: Cadillac Desert by Marc Reisner, Where the Wild Things Were by William Stolzenburg, and The Golden Spruce by John Vaillant. Honestly, there's so many good books on parks/conservation out there that I'm not even aware of, so I'm always looking for recommendations as well! Hope this helps!
(Also, shameless plug for my Patreon lol. There's a book club tier on there where we discuss a park related book/movie/podcast/game/show/whatever each month. There will be some good recommendations on there too!)
A Walk in the Woods! One of the best books I've read. Hilarious AND informative.
@@adventurecreations3214 I agree!
I go here with my housemate as often as possible. It helps me reconnect. You should go. This is an experience!
One day!!
I did a bike ride around the rim. Lovely. Crater Lake is also Earth’s deepest lake the bottom of which is above sea level. There is a similar lake in North Korea. A flight of P-38s once flew some laps within the rim - loud military thunder.
From Nat’l Geographic Magazine back issues I learned of ‘the old man of the lake’ - the trunk of a fir tree bobbing vertically upon which a person might sit. It may still be there, but if not, it may be replaced by another. A tree growing on an inner slope is taken down in a rockslide, it’s roots clutching stone. It floats free and vertical with a rock ballast. Neat.
I bet that was a pretty ride! Were you touring or just out for a day ride?
@@NationalParkDiaries I was in my early fifties and had just moved from glaciated landscape in eastern Pa. In good shape for hills, but I felt the altitude at Crater Lake. The rim ride is about 34 miles and goes way down the outside with a big climb back up to the visitors lodge. I love the old geology back east, a volcanoe is pretty new but gorgeous under blue autumn sky.
how deep could a clear, acrylic, round elevator go down into the lake?
cool idea?
Do a Theodore Roosevelt! How he’s a big part in conversation both with public land and hunting
Absolutely. Definitely want to do a video on him. Would love to travel to TR National Park to tell that story.
I have visited Crater Lake three times.
The first time was in June of 1978, after a winter where there had been thirty feet of snow on the mountain. Snow plows were still keeping the rim road clear, and half of the perimeter road was closed due to nine feet or more of snow.
The next time was in May of 2015, and there was very little snow on the rim, only in small northern shadowed areas.
I took my daughter to see the lake in July of 2017 and there was no snow at all.
I interpret these differences as proof of climate change.
The portrait you showed, was an artist's conception, and appeared in National Geographic Magazine; at the beginning of an article about Crater Lake, about fifty years ago. The Article stated that the Eruption took place, about 5500 years ago, and was, at that time, believed to have been one of the biggest, in recent North American Geologic History. It produced about 42 cubic miles of ejecta, sent pyroclastic flows down the Rogue River, as far as McLeod, and blew an estimated 4000 feet, off the top of the Mountain, which may indicate, that before the Eruption, it was about the height, of nearby South Sister, or Mount Adams.
Coming from "Why I will NEVER VISIT Crater Lake Oregon
" video from Hidden Files.
Still, very nice lake and would like to visit.
As someone who has been to Crater Lake a half dozen times in the last few years, dare I ask what silliness that other video presented? Feral people who steal children?
@@johnchedsey1306 nah, just copypasta and heresays
Haha, I'm glad!
Dude how do you not have more subscribers than you do.... This is some AMAZING content!!!
Haha, thanks! I'm just trying to put out the best stories I can and all who want to learn about parks are welcome here!
I am not from the US but I was inspired to look for this place after playing Days Gone an amazing game! This lake is one of my favorite, want to visit it someday!
lol, I played that game too! So satisfying driving around the lake on your motorcycle!
@@NationalParkDiaries It is, the world is very beautiful and breathtaking! And yeah the ride is amazing everytime!
That map of the volcanoes in the Cascades showed helens in Washington...
The lake I live near is most likely also the result of a large eruption of the nearby mount konocti
Hmmmm I was there this year on May 10 5 to 6 ft of snow and 42 degrees at 3pm?
All the missing water goes to level 7 of the backrooms
Seepage… that’s the same reason my underwear don’t overflow.
Wonder how crater lake was affected by the stocking of fish to begin with. Do the fish help or harm water quality/clarity?
Fish add nitrogen and phosphorus to closed ecosystems. Fish poop fertilizer. That’s helpful to plant life. In the absence of abundant vascular plant life, algae will flourish as it doesn’t need much. So in isolation I think fish would invigorate all plant life.
@@ladyeowyn42 I’m not sure much plant live can survive it’s really cold water
I wonder what would happen if this happened in our modern times
Loved the video I love in a town called Mount Gambier but It is also called crater city by lots of locals as our towns water source is in a old volcano and the the surrounding areas are full of craters 🙂
Thanks for watching! At first I thought Mount Gambier was somewhere in the US, but then I looked and it's in Australia! Greetings from the US lol!
@@NationalParkDiaries no problem! it's easy when it's good content 😊😉
😊😊
Nnn
CA wants that water!!
Your date on the Mt. St. Helens footage is off by around 9.75 years.
That date is from when the archival footage aired, not from the eruption itself.
How did fish get into tbe lake since it has no streams feeding into it?
Birds
It's called stocking, try reading the other comments.
The fish were stocked in the late 1800s by early pioneers and now they want the fish out because of the sediment they are adding to the lake but good news for angler's all the trout and crayfish you can eat no fishing tags needed
Twopiecies of music tell the story of the Mazama. Mazama is about the eruption itself, and Fires of Mazama is I think is more of the destruction that it caus. But I'm not 100% sure. Either way, theyr great pieces
How did fish get there if no streams flow into it
Crater Lake was stocked starting in the late nineteenth century.
2:47 This is a common misconception. The ultimate fate of subducted plates (the first of which entered the mantle 3 BILLION years ago) is a subject of much debate in geological academia. Is the mantle just a graveyard of former subducted plates, or is that material recycled somehow, eventually joining the mantle rock? We don't know. *However, we do know that subducted plates do NOT melt.* What actually happens is that the hydrous mineral phases within the subducting plate "dry out," releasing their water due to the increased heat and pressure they experience at depth (125 km, give or take). The water enters the mantle of the overlying plate (in this case, the North American plate), where it lowers the melting point of certain minerals therein, causing them to melt. The magma, being liquid and less dense than the surrounding rock, has enough buoyancy to force its way upwards, eventually entering the crust of the overlying plate. It changes due to a variety of processes (which can both remove and add material to the magma), so that the composition of a magma that eventually erupts at a volcano is quite different than the composition of the magma when it formed.
The explanation given here is better than most though, as it includes the formation of magma from the overlying plate.
Ah, I see! That makes sense, thanks for the correction. That was a pretty tough geologic concept to learn for a non-technical person, so I'm at least glad I got most of it correct (and that it doesn't change the point of the video lol). Thanks for the input!
@@NationalParkDiaries Yep, no problem. A lot of sites use technical jargon to explain this concept, so it can be quite difficult to "get" for someone who isn't looking to actually learn geology. I used to teach this stuff to 18 year-olds taking their mandatory science credit at university. I guess they figured that geology would be an easier elective than chemistry...unfortunately for them, geology includes a lot of chemistry, and I'd go into reasonable depth where necessary. So be thankful I'm not yammering on and on about silicate chemistry or Bowen's Reaction Series. :-)
I enjoyed the video. I visited Crater Lake ages ago (still have a couple small pieces of Mazama scoria in my rock collection) and consider it one of my favourite US national parks (maybe top 5...Hawaii Volcanoes NP is #1 obviously, and Yellowstone and Zion are #2 and #3 respectively). It's just such a peaceful place, considering its origins. It has been awhile since I've crossed the 49th parallel to explore America's wilderness (Covid, and the politicization thereof have made me a bit wary of travel to the USA), but hopefully, once the price of gas goes down, a decent road trip is in the cards.
@@VoIcanoman Haha, yeah geology was, admittedly, never my strong suit either. I did well, and came to understand things in general, but it was just one of those subjects that were harder to retain for me. That's why when I do research for these videos I really try and understand the concepts in depth before relaying them to my audience. In this case, my source was the USGS itself! Guess they need to update their literature lol. Anyway, thanks again for the correction and thanks for the conversation!

How did the fish get into the lake after it formed if no rivers go into or out of the lake? Did the indigounis people seed the lake with fish?
The Lake was stocked, but by white settlers in the nineteenth and twentieth centuries: www.craterlakeinstitute.com/general-natural-history-articles/animals/fish/fish-of-crater-lake/
how did fish get into crater lake?
Because the caldera is so young.
