I watched Mt. Saint Helen’s erupt through a telescope when I was 4 years old with my dad somewhere in East Olympia. We also (unknowingly) rented a house (from a bank) that had belonged to a young family who died on the mountain. We moved across the country when I was 6, but I have always been strangely fascinated by the mountain and now, 46 years later, went to Johnston Ridge for the first time this summer. Thank you for this great video.
Thank you for your story how exciting
That's insane to see how the landscape changed from before and after the explosion within two decades. Makes me wonder if it actually takes millones of years for landscapes to form.
interesting makes me wonder the same
Right. I agree. Mt St Helens has taught us a lot.
From seeing the recovery of St. Helens, I can say safely that the recovery is much faster than I thought. In about 40 years, the plant life around the mountain has recovered significantly. I would confidently say that in 300 years, the trees will cover most of the pumice plains, and the lower areas of the mountain itself. It will not seem barren like it does now. The crater may not recover for a long time, but i am open to surprises. :)
Trust the scientists. They have no reason to lie to you. If you think they do, it must suck being you.
@@qpwodkgh2010 so should have the Germans in the 1930s trusted their scientists when they stated that the Jews were of an inferior race because eugenics proves it? Should the public have trusted the scientists who created nuclear weapons as a means of self defense? Should the folks in the 80s have trusted the scientists who predicted that we would have an ice age in the early 2000s? Should the public trusted the scientists who were paid by tobacco companies to say that cigarettes did not cause cancer?
There's two type of scientists I don't trust. The one's who have a clear agenda with zero ethics. And the ones who think they are highly ethical in their statements but don't admit that they can be wrong.
I don't feel bad that you feel that way about me. I feel more bad for you who believes everything the "experts" tell you. I bet you don't trust every politician, even if they have preparation and an education. I bet you don't trust every doctor because of the clear evidence of big pharma that keeps people unhealthy and in debt. Why would you trust every source without questioning their legitimacy? That's what I find sad of you.
This was fascinating, thank you.
The time lapse from 1984 - 2019 reveals massive deforestation on the eadge of the forest..
That was all I could focus on.
You guys didn't care when the volcano did it. It's actually healthy to do this and keeps it all from burning down to nothing. It allows undergrowth to see the sun to ensure a strong future for future trees. This is why Superblooms happen. Nature has a backup plan for everything we can throw at it and that it throws at itself. If you can't see the recovery after destruction after the volcano and how resilient it is then, I can't help you. There is more to a forest's sustainability than how it looks.
It’s painful to see the encroaching harvesting of the forest.
Well, I grew up in Oregon (and took classes in environmental management - long ago) and unfortunately clear cutting is common (easier then the older version of selecting certain trees, and cost effecient). We depend on WOOD, Paper and other products made from trees. (although now hopefully some is recycled!) Earlier in America ENTIRE species were WIPED out from the demand on natural forest. (certain types of Chestnut trees, Oaks and Maples many others) Later laws created a better balance. There are many other species that are destoyed esp Tropical forest (and each area has specific flora and fauna all destroyed as the creatures depend on the plant life) and so once gone gone forever.
People around the world that want products from these places aid in their destruction (and attempts at "cattle farming" proved a disaster - the soil was thin and nothing else would grow on it) (roots of these trees shallow).
If you watch, you can see the replanted trees grow after the clear cutting.
Weyerhaeuser replants the clear cut.
Not saying they’re perfect, but logging today is done more sustainably today (speaking in the US) than decades past.
Do you find it painful to realize your house is made of trees?
Then don't watch. You have that choice.
Trees are a renewable resource
My grandfather worked for Weyerhaeuser for 42 years. In a location near Pe Ell there was a plot of land that the company owned and deemed Stockholder’s Park. It was 300+ year old Old Growth forest.
Interesting how they held off cutting 300 year old trees for the "owners" of the company.....
How about making it a public sanctuary..??
I was at school in London when St. Helen's erupted and we got sent home at midday as the sky was black.
I walked home holding my 6 year old sisters hand she didn't understand and I had trouble explaining it to her.
I was 8.
In London? UK?
Honestly the man made tree cuttings destroyed more area then the explosion. So sad to see so many trees cut down
I agree that it should be banned in certain areas (was active in Oregon for ages - but the Timber Industry usually wins out because of the DEMAND by the "collective".) We all use trees. It happens to our American Forest all over (many from early America extinct!!! (some from imports that carried insects not native to our flora and went extinct - some cutting every last tree down) I recall the Redwood Forest in CA - and hiking along - nice stand of the oldest living thing on Earth, walk a tad beyond and these giant trees were stumps!!! (used for HOUSING!) Big backlash to at least preserve a small tad!
We all are involved (you know YOUR house, YOUR paper products so on - the wood and by products - paper comes from trees. NOT due to activism - many are grown on land for that purpose - tree harvesting from crops like any other crop). Lived in S Oregon and one can see the squares from this clear cutting. Not as horrific but better then in the past (early America) when the ENTIRE forest was removed (along with other flora and fauna that depended on these trees) (Ditto for the Tropical forest around the world)
The most alarming thing about this time lapse is the clearcutting that is happening.
To introduce a proper understanding of scale and time -1,000 years from now, barring another major eruption that kills everything, that will be some of the most fertile land in the area.
Not to be all hippie, but the multiple clear cuttings irk me
Renewable resource. It grows back.
Usually I would make a crack about how that is a fine sentiment if you don't mind going without toilet paper...but never mind.
Logging in Oregon got shut down completely. There is no longer any balance it completely swung from one extreme to the other. Right and wrong should be exchanged for tug and pull. And for pull not to show up to meet tug any longer life becomes chaotic and imbalanced. We could of done a much better job in Oregon; now all our forests are overrun and matchbox prone and no longer any roads created and maintained to slow fires down when they start. The list goes on. It's not all rainbows when you end logging. It's not all rainbows when you let logging companies go willy Billy. People want to complain about the trees and animal displacement. What about when you don't use Logs? Resin compounds, plastics, petroleums, metals.
How can logging make people sad when it can regrow while other methods don't regrow and cause equal if not more damage? It seems like a large percentage of the people arguing about logging don't have the slightest clue about the environment and they can claim they are siding with nature and science but their ignorance and lack of research shows in bright colors. Completely going off emotion (far too many people with more influence / louder opinions that have even less wherewithal than I)
Not directing to the original commenter just something I felt like sharing here.
@@coleman318 My Father was a forester for Weyerhauser in the 1950's and 1960's, an old-school Democrat. I believe he would agree with most of what you said.
You think if Blueseaview22 was correct he would actually say something logical that we could somehow talk about. Not just vomit his shadow in massive projection through comments on TH-cam. Luckily when people get angry and go to insult another person they usually point out their insecurities and flaws and label that other person as the very thing they are.
Fun fact those logs, the bark stripped off and settled to the bottom. Theory has it, that is how coal is made. :)
@Jeff Rock And TIME!
No "theory" and mostly in swamp, bog areas BUT - OVER hundreds of millions of years!!! (longest of any rock formation). (I had to take Geology and thought UGH but turns out to be very interesting - from water systems, rocks - mountains and other envoronments) (Coal can be made from any plant life) and a process at that (where PEAT bogs come from - peat is a step further down from coal). IT is considered a "non renewable resource" because it takes multi millions of years to produce. Luckily few nations use coal (overseas nations still do) Charcoal is a different matter.
*_I climbed the North Face of St Helen's in 1971... it is now gone... blown over 200 square miles._*
Great video presentation. Would like to see a video of the mountain itself and the rebuilding of the crater again. Been watching it from Mt Calvary Catholic Cemetery since 2008. It's definitely filling in more and more.
How do you feel about the use of seeding (with non-native / invasive plants) to help stop erosion right afterwards? Is that still impacting the forestation and the wildlife that's returned to the area?
Nighmare for the natural balance and eco system. Nature knows how to restart and has been doing so sucessfully long before human kind. Volcanoes enrich the soil as well.
Thanks for a wonderful trip around the area .
Not forests ! Tree farms ! There's a big difference. 50 times less board feet in ten times the number of trees only a hundred years ago.
And now many of those tree farms are ready to re-harvest, saving pristine forest.
Here's a question for the habitually unproductive. Since the green crowd and the lockdown crowd are one in the same. How many trees were cut down to make useless paper masks? And how many of those masks are now litter?
@@steveadams7870 Very few trees are being used for making masks. Most masks are actually plastic, not paper. If they were paper, they’d likely disintegrate in water within a couple months, which they don’t.
@@coveredinmoss Steve suffers from cognitive dissonance. Do not engage.
@@coveredinmoss Much paper is from recyling. Most of the mask were paper AND having studied plastics in the arts the toxins to produce plastic (made from OIL btw) and refuse is horrific. (ocean ships dump their refuse at sea, plastics then eaten by sea life, turtles others and choke to death. It takes hundreds of years to break down (although some now are made to disinegrate faster)
@@steveadams7870 I studied this area at S. Oregon when in college (environmental management where the forest ferns and wildlife were key issues, along with water systems). First these "farms" are staggered (on average 9-10 years before harvest). When buying paper products CHECK the label - "made from recycled paper"!!! Otherwise many species of beautiful trees are destroyed for what (or yeah since the computer who needs it???) (aspen eucalyptus, maples, birch, aspen, and oaks) Beautiful areas along CA Coast Eucalyptus - most now extinct!
Better MHO then clear cutting trees hundreds of years old!
Christmas trees are grown in this manner (better then cutting down our pine forest or what's left of them)
There is only a minute amount of the once vast range of Redwood forest (and other trees) in N CA - thousands of years old (oldest living thing on earth now). Clear cut to almost extinction. (small amount saved to to "outcries". All to make HOUSES!!!
That was long before the "green crowd" (what ever that means).
the saddest part of the timelaps was that human deforestation in the sorrounding areas was way faster than natural reforestation in the "moon scape" area
Can't wait 4 the next 1, this is interesting stuff 👍🏼
Hi everything looks amazing and I’m learning so much stuff! Hope you are safe and sound!!
watch this channel for science videos
TS Knowledge ok!!
I was there at the eruption. It was scary. I was at the Cle Elm Ranger Station when it happened. At 8:30a.m. the call came out to clear the park.You could not see 6 feet in front. It had the blast ratio of 5 Hiroshima.
I live in WA and thank you for this info. Fascinating.
Its chilling to know that a photographer was there the day it erupted and got turned to ash.
Not even ash that dude was completely vaporized
Not how it happened at all! Two people died and WERE miles from St. Helens. But not VAPORIZED at all (easy to research but I was in S. Oregon, Sisters in WA at the time) And don't forget David A. Johnson (geologist monitoring the activity" and his statement "Vancouver, Vancourver, This is it! (body never found) Observatory named in his honor.
(One death: Landsburg - he was able to make it to his car "snapping images along the way" but obviously at 400 mph the ash and toxic gasses overcame him. Official. "Death by asphyxiation by volcanic ash near his station wagon parked near Sheep Canyon in the upper South Fork of the Toutle River - FOUR miles form Mt. St. Helens" (Source That Oregon Life - but many other sources) He continued "shooting from his car window as the pyroclastic wall of ash approached" his car. Final roll, he rewound it put it in its canister then in his backpack (and almost makes me cry) "THREW his body on top of it, effectively shielding the delicate film from what was to come"!!! (like the war photographers!) His images show the oncoming super heated blast coming his way!!! (600 F and traveling 300 mph full of stones and other items)
Photojournalist Reid Blackburn - 8 miles away - on assignment for his newspaper (The Columbian) as well National Geographic. Changed his plans to leave and decided "to stick around for a few more days to see what transpired" Campsite at Coldwater Creek and like Lansburg "his vehicle was the only option for shelter from the blast) (which of course was blasted!!!) His car was discovered burried under near pyroclastic flow! (windows busted open - no one would have survived these blasts. (more powerful then the Atomic bombs) His film of the blast was destroyed by the blast, but unknown previous images from a helicopter were discovered. (undeveloped film) (pre eruption) As well archives from The Columbian - took 30 years for much to be developed)
(and in total 57 or so people) (many refused to leave)
That was so cool, thanks.
Wow that time lapse shows forest growing back up around the mountain but farther out it’s being destroyed by humans.
4,000 trees were planted not long after she erupted. It's amazing to see what she now looks like today 42 years later as of May 18, 2022
I wish nature would get way more credit for healing itself than what any people could plant.
Amazing ❤️
Dang you see where humans cleared tons of trees. We wiped out tons of forest
Everyone uses trees and paper - try to buy "recycled" (studied this decades ago at Sourthern Oregon - environmental mangement) At least now "tree farms" (many species of trees MANY went extinct in early America due to this callousness!)
@@sazure2 here in Oklahoma there used to be wild persimmon & wild PawPaw trees all over and now you rarely see them. The United States used to have wild chestnut trees all across the country and we nearly wiped them out. I learned that about the chestnuts in a deer management study
I'm wondering if the trees that came down from the eruption were used for lumber?
In our backyard natures greatest fury demonstrates to us how minisquile nature is compared to the clear cutting done since the eruption. I hope nature can recover from that... with out killing us.
Been there many times. Interesting mapping
But where is Lance at?
All i saw was continuous logging not giving the area enough time to regenerate
I know right
The person who disliked this video
Why?
@Flavius Stilicho Or some tree-huger pissed about all the clear-cuts popping up everywhere.
Usually most dislikes are made by spambots, not real people.
@blueseaview 22 You know me so well, Troll.
Kid or a bot or some other kind of thing TH-cam doesn’t care about
It was sad seeing how much habitat loss there was around Helens for human development. Like who did the most damage to the environment here, the humans or the volcano? lol
There is habitat loss all over America - look at a map of early America before we came along. We are now in a 6th mass extinction (from small sub forms to mammals) I studied this long ago but many many species of trees (and other flora and fauna) extinct because of our leveling land to build cities and subburbs! (and plant GRASS!!!) Prairies gone so is the prarie dogs (but much effort to preserve and rebuild these lands now). And many other environmental types long ago destroyed.
Yay you and landsat!
pretty amazing...
At least Mount St Helens helped out the logging company by cutting down all the trees for them.
Guy sounds like toby from the office lmao
Many people upset about the "clear cutting" ( I as well) lived in S. Oregon and one could see these huge cuts. But better then in Early America when entire forest were cut down (now many in Tropical forest and many extinct along with flora fauna) Ditto with our American Forest - many now extinct.
This was a solution - it allows an area to be harvested, new plants in and over time the environment and animals on it change (part of my research but one can look this up) Many other species were able to utilize these areas and as they changed moved on. (The US is not going to return to hand cutting as in the olden days - too many people building HOUSES, and using PAPER products!!!) Reclyed paper (read the label) and wood can be reclaimed from houses taken down (much now crap plyboard so on) but original old hardwood can be found) Still entire forest are being destroyed in other countries. Esp exotic species! Many now going extinct due to demand. (and gain become informed and DON'T buy)
did you see the deforesting time lap? all those brown spots. thats are oxygen
Music at 1:40?
amazing
Bro finnish the Video before u write a comment 🤣
Ikki Kurogane bro doing alot struggle and hard on video so just want fews views and subscribers☺️🙏
People makes much more devastation then volcano.
Cool
Watching clear cuts is watching forest rape.
Thought it was a mountain in space
All the clear cutting Thats more dramatic to me!
The clear cutting is crazy
Hi
2:41
Vesuvius in 79 AD
Dude used the word moonscape like 5 times in 30 seconds.
Wahoo !!!!
All I see is deforestation from these satilite photos
watch this channel for science and knowledge
Rather than watching it for spongebob fan fiction
💖
A true promotion video for Landsat... How cheap.
👍👍👍😀
I flew a plane into the volcano in 1980. Time to admit it. Sorry harry.
Landsat de arse e de kick a dee
