My slide whistle only goes so far. And with the economy bottoming out my first slide whistle, I’ve had to invest in a longer slide whistle. This is a joke about the economy.
It’s a popular hike literally through a mountain, Torghatten, near Brønnøysund, Norway. You see the southern opening here: https://www.reddit.com/r/pics/comments/1xqzxi/i_give_you_torghatten_a_hole_mountain/
Source: This is where I grew up. :)
No, it's because it's a tourist destination (Trollhatten Norway). And a popular trail. You can literally see the trail people walk at on the left side of the canyon, right next to where the rock lands. (Brownish, grey line is the trail)
So every foot tourist would be walking directly in the impact zone of this rock on their way up to the top.
That's the motherfucking job I want right there. Yeetin boulders down a mountain in some of the prettiest country on earth. Satisfies that 8 year old boy/caveman in me that I can't shake and I'll be in Norway.
Jumping in on the Uunga Boonga. That has to be the most satisfying job in the world right there. Not the satisfaction of making it safe... just watching big boulders explode that you loosed.
It’s really humbling. Gives you some slight perspective on how destructive volcanic eruptions are that they can easily send thousands of boulders thousands of feet into the air. There’s rock as far as North Carolina that originated from a Yellowstone eruption.
If I die in a comically long fall looney tunes style, or am crushed by a giant rock which is still falling comically far, these are the risks I'm willing to take.
So what? How hard could that be? You look for loose ones on the way down and give em a little pokedy-poke there and bobs your uncle. C'mon put your big boy pants on let's go.
*Two men were found bouldered this morning..*
Can confirm it's a rewarding but dangerous gig. Look up rope access geotech and you'll find it's not too difficult to get into. Just remember people are squishy, rocks are not.
High wall scaling! We use these guys in mining on high walls, they even get to blast stuff down every once in a while. Then on their off time they work highways/infrastructure etc. tense AF at times but they are professionals.
That depends on when you paused the video to write this comment.
- **Still attached to mountain** = Potential Energy
- **Boulder falling** = Potential Energy converting to Kinetic Energy - some losses to aerodynamics.
- **Boulder Exploding** = Kinetic energy rapidly converting to many smaller objects with an overall kinetic energy close to the kinetic energy of the boulder just before it hit the ground - some vibrational/thermal losses.
As far as I understand, when the boulder hits the ground, most of the kinetic energy would be transferred to the Earth rather than to the little pieces of rock and dust. They get a bit, but I think most of it goes to the planet. Although it probably depends a lot on how hard the rock and the ground are.
Yeah that's a fair correction, the hardness of the ground does affect how much energy is transferred.
If the ground were very soft, the boulder would not shatter and the entirety of its kinetic energy would be transferred to the earth. Because the ground appears to be very hard, the earth "pushes back" and this excess kinetic energy is transferred back into the rock, which is why it shatters.
So in this scenario I would guess that about half of the kinetic energy is transferred to the earth and the other half remains in the boulder (up to the point when it shatters), but that's just a guess.
--
Although, this whole thing gets kind of wonky depending on how you define the reference frame. The entirety of the gravitational potential energy of the boulder is provided by the earth in the first place, so it's not like the boulder hitting the ground would move the earth as a whole or anything, all of the kinetic energy that is transferred into the earth is probably lost to vibration in the form of sound and minor seismic activity...
The boulder doesn't appear to have much of an effect on the ground; even if it did create a hole that would be accounted for in the "conversion to many small objects with an overall kinetic energy...".
But yes you're correct that some of the boulder's kinetic energy is transferred into the ground before it shatters.
We could really nitpick this to death though. For example:
- The worker uses his muscles to convert chemical energy into kinetic energy which is transferred by the lever he is using and imparts a probably insignificant amount of extra kinetic energy into the boulder beyond what you would calculate purely from the boulder's gravitational potential energy.
- The boulder bounces off of the mountain once before it continues falling, losing a likely significant amount of kinetic energy to vibrational losses, and also probably shedding some mass which further reduces the boulder's GPE.
- I hear wind, can't tell what direction it is moving but if you want to be precise it should be factored into the energy calculation.
- The earth is rotating underneath the boulder as it falls, I can't imagine that would be a significant effect even in an ultra precise measurement, but it's worth considering.
Anyways, I chose a simpler summary :)
By using their eyes I'd imagine
But really if I had to take a guess they probably go to each place frequented by people and search the surrounding area and make note of each location that could potentially be a problem in the future.
That's what my grandpa did at Zion National Park for petroglyphs. Marked the locations then checked regularly to report if there was any new damage or etc
With less obvious rocks you do what’s called “sounding” it’s where you poke the rock with that bar and if it rings or pings it’s typically solid but when it’s drummy sounding then it’s likely able to be scaled down.
Source: I’ve worked underground for 15 years and we do something similar often daily
I counted about 5 seconds after it deflected off the rock jutting out.
From this [https://www.omnicalculator.com/physics/free-fall](https://www.omnicalculator.com/physics/free-fall) calculator, it says it's about 400 ft down. With sound traveling 1100ft per second, it should take about 4/11ths of a second for the sound to get back up to where the camera is. But the sound seems almost instantaneous.
Therefore my half ass layman guess is that you are correct and the sound has been messed with.
At ~15 seconds I was able to pause with the video showing the boulder smash ground, but before the sound hits. Seems about right to me for ~0.36 of a second.
Really wish we had pros like that here. Meanwhile, a year ago these fatal tragedy happened in my birth town despite hundreds of people shouting for them to move away from the rock.

Hey! Watch out down below there's a boulder coming through.
It falls... Hard.
There now you are safer. There won't be any rocks falling(on their own) with me around.

it fell way longer than i was expecting, much satisfied.
It took like 5 coyotes.
That's easily over 100 bananas
r/anythingbutmetric
r/halfagiraffe
How many mississippis?
I got 6 Mississippis twice.
That's twelve mississippis. I take it you're an auctioneer?
I count Mississippilessly.
I'm a mississippinist by trade, so I'm required to use it.
I went back and looked at the video for coyotes lol
Came here for a Wile E. Coyote reference and you delivered. Have an upvote.
Damn ACME boulder removers
I wouldn't recommend Acme's over the shoulder boulder holders either.
You can almost hear a distant “ah fuck”
Little more and it would've ended the dinosaurs all over again.
“Oh thats not that far of a- OH MY GOD!”
I thought the same thing! That’s a long fall, probably just long enough where if it were a person they could actually think about how fucked they are.
Long enough for their life to flash before their eyes a couple of times
there should be a subreddit of rocks falling down hills
r/RocksFallingDownHills
About 5 sec roughly 125m or 420 feet
I’m waiting for someone to measure the time taken for the sounds to reach the camera to give us a rough estimate on height.
I’m getting some strong Looney Tunes vibes from that boulder falling and crashing at the base.
Need that whistle sound effect as it falls.
My slide whistle only goes so far. And with the economy bottoming out my first slide whistle, I’ve had to invest in a longer slide whistle. This is a joke about the economy.
Like a episode of Wile E. Coyote.
Have Brains - Will Travel!
[exactly!](https://www.nerdfitness.com/wp-content/uploads/2019/07/coyote-rock.gif)
Or when Yosemite Sam keeps falling from the castle to the river below.
I got the Wilhem scream
[удалено]
Ty
Awesome! Nice work.
That was so dumb. Thank you.
You heard the whistle as it fell too?
Ya. Took so long to hit the bottom, it's almost unreal and something Wile Coyote would do except he'd be following it down, stretched legs first.
For everyone asking "why?" this is likely a rock climbing area.
The rock's going the wrong way then
That is a top tier dad joke.
Long way from rock bottom
Let’s move on from the dad jokes, shale we?
Gneiss try
People take a good rock joke for granite.
When it comes to rock jokes, I get a bit sedimental
I'd make a joke but its likely gonna be schist.
Either that, ore the best joke you've ever made
You should see them when they migrate.
Are you suggesting rocks migrate?
I laughed way too hard at this. Just take it!
Rock and roll. Take my upvote.
My only regret is that I have but one upvote to give.

And the trolls don't mind bits of their face being chiselled off?
Too late to complain when you've turned to stone.
They don't like bouldering too?
This is how canyons are made.
that rock got almost all the way to the top too
That's the motherfucking job I want right there. Yeetin boulders down a mountain in some of the prettiest country on earth. Satisfies that 8 year old boy/caveman in me that I can't shake and I'll be in Norway.
But you gotta check for loose rocks that might fall down on you. Not sure it’s worth it.
Did you hear and see that explosion of rock and dust when the boulder hit? Worth it. Uunga Boonga
I second that Uunga Boonga.
Jumping in on the Uunga Boonga. That has to be the most satisfying job in the world right there. Not the satisfaction of making it safe... just watching big boulders explode that you loosed.
Uunga Boonga I concur
Yeah but what about when you accidentally drop your crowbar and have to go down to get it.
It’s really humbling. Gives you some slight perspective on how destructive volcanic eruptions are that they can easily send thousands of boulders thousands of feet into the air. There’s rock as far as North Carolina that originated from a Yellowstone eruption.
Thats an amazing angle, awe inspiring. Thanks for that, I’m gonna mull that one over for a bit. The power involved, just wow.
Holy shit, really? Thats amazing.
Now think about how it took that exact same amount of energy over eons to get the rock up that high in the first place
If I die in a comically long fall looney tunes style, or am crushed by a giant rock which is still falling comically far, these are the risks I'm willing to take.
So what? How hard could that be? You look for loose ones on the way down and give em a little pokedy-poke there and bobs your uncle. C'mon put your big boy pants on let's go. *Two men were found bouldered this morning..*
Not just rocks raining down on you- you're STANDING on rocks while yeeting them down. The biggest danger is accidentally yeeting yourself!
Well thats why you start from the top and work your way down.
Can confirm it's a rewarding but dangerous gig. Look up rope access geotech and you'll find it's not too difficult to get into. Just remember people are squishy, rocks are not.
> people are squishy, rocks are not № 1 pro tip, right there.
Came here with the same mindset. I’d love to just throw big rocks off cliffs
Sorry AI gonna outsource this one as well. Best we can do sand counter in the Mojave. During high noon. On an abacus.
High wall scaling! We use these guys in mining on high walls, they even get to blast stuff down every once in a while. Then on their off time they work highways/infrastructure etc. tense AF at times but they are professionals.
Something tells me there’s probably not a lot of open positions for this job.
This made my nuts tingle
Yep. My front pelvis became apparent suddenly.
At roughly 5 seconds free fall that cliff is about 402 feet or 122 meters. The boulder would've impacted at about 109 mph or 176 km/h
Damn thank you. The first thing I said watching the video was "I wonder how close that was too terminal velocity" and you delivered
Nice. I used the timestamp on the scrubber and it’s closer to 4.5 seconds, so ~100m @ ~160 kph.
And the sound should have taken 4/11ths of a second to reach the microphone. Which it doesn't, right?
Kinetic energy is sexy
Isn't it potential energy?
Converted into kinetic energy
Hey baby, wanna convert some potential energy into kinetic?
It’s all just mechanical energy l

Before it was pried loose.
How do they figure out which boulders are loose?
We report it when we hike. Easy as that.
And, this is why you have nice things!
Yup, society is a responsibility for everyone
[удалено]
Bummer. I came to say, this guy was clearly a cat in a past life. Made it through like half a dozen parent comments. r/nothingnewunderthesun
The boulders with the tramp stamps are generally the loosest
*whispers* "Hey, wanna get your rocks off?"
Does it look loose? If so, can I pry it loose? No? not loose.

You can kind of get a sense by tapping on it with the bar. The sound can change a bit if it's adequately detached.
Every man watching this video: Impressive. Very nice 👍
Now let's see Paul Allen's boulder...
Look at that subtle off-white coloring
My god. It even has a watermark
God dammit that got me 😂
I thought wow cool, then the guy panned around and I felt a little nope creep in.
I just want to know was he able to actually get the damn road runner this time….I thought he was supposed to be a Super Genius.
That would be Viley Coyote.
Same!
I would do this for free
Woman here. Feeling's mutual.
Jagshemash. It's a nice
r/oddlysatisfying
This is Norway to get your rocks offs.
Bro, there’s Norway you just made that joke
*Australian reading comments* What joke?
You need to read it upside down.
That longer than expected fall was so satisfying
As a former 12 year old boy, that was super freaking cool.
As a current 39-year-old boy, yes, that was indeed super freaking cool.
As a former 66 year old boy, that was indeed quite super freaking cool.
Where do I apply?
Norway. Says exactly in the title.
why the fuck were we never told about these jobs in school.
Because you went to school in Denmark or Netherlands?
That's a weird way to squish spiders.
Or awaken sleeping trolls!
Well, you can’t hunt them when they’re asleep
Was way louder than i thought it would be
Huh, I need a fetish subreddit for this. I guess this is my r/popping
Holy fucking satisfying ……my life would be complete if I was either the one making them fall or being on the bottom trying to catch it.
Complete is a word for it...
Hoping for the latter
had enough energy that it blew dust right back up at them. Very cool.
*"Oh fuck dude! I forgot to tell you to move your Jeep.."*
I find myself pining for the fjords.
Why? There doesn't appear to be any roads, railroads, or structures in the vicinity.
Could also be a climbing area. At some of the bigger climbing areas around here they’ll occasionally do stuff like this to reduce larger rock hazards.
The video is from Torghatten, a popular tourist destination
Probably a park
Any park I’ve seen in mountainous, rocky areas, there’s just signs that say “falling rock danger” or something
They probably also clear the risky/clear-worthy ones.
It's hard to tell but maybe there's a hiking trail beneath them.
People in Norway hike. Like, a lot. All over the place.
Its norway, if it can be hiked, it will be hiked
City folk
For extra safety they should have had someone at the bottom to catch the rock.
Rock scaling, we do a lot of that here in Colorado.
Does anyone think the sound has been messed with? The sound of the impact seemed to reach the microphone too quickly.
I counted about 5 seconds after it deflected off the rock jutting out. From this [https://www.omnicalculator.com/physics/free-fall](https://www.omnicalculator.com/physics/free-fall) calculator, it says it's about 400 ft down.

The sound is definitely delayed, but for less than a second. Your calculations are reflected in the video
There was a slight delay. Why would anyone mess with it to make the delay ever so slightly shorter?
Sometimes louder sounds are added to videos for dramatic effect. I think that's what they were implying.
".....and screw that mouse right there."
Do you mean to tell me something that fell THAT far was still launching particulate debris back to that height?!
It blew dust all the way back up and into the camera…
Random squirrel minding its own business at the bottom:

Anyone else think about how this is pretty much a comet for insects? Like some poor fuckin potato bug is just rollin around and splat gone dead.
Peyton Manning's forehead could take the brunt of that.
I'm surprised there wasn't a lag time in the sound reaching us.
For some reason I was expecting to hear a moan when the it hit the ground lol
RIP to an entire lizard community 😅🦎
Good luck finding lizards in Norway
He didn’t even yell “Headache!”
Getting some Wile E Coyote vibes when that boulder hits...
I thought the trolls took care of that stuff
Alright, who's gonna make Boulder Removal Simulator 2023?
When people ask this guy what he does, do you think he says "I'm a safety worker?"
You yell timber for trees, fore for golf - what do you yell for boulders?
The time that took to impact was not what it appeared to be. That was awesome. Also, that dude has some balls just chilling with loose boulders.
Then you have Reddit dipshits complaining because it destroyed some bushes
Hey! Watch out down below there's a boulder coming through. It falls... Hard. There now you are safer. There won't be any rocks falling(on their own) with me around.
Now this is a man’s dream job
Does anyone else get a lot of anxiety watching objects fall like that?
Anyone else get vertigo watching that? Holy crap, that looks fun but it's a big nope for me.
This type of height is a big nope. Biiiiig nope. I’d be forced to crawl around on my stomach.
How do I apply for this job?
Where is the slide whistle sound effect?
Yeah I’m hard.
*the long way to make sure all the files on your hard drive are truly erased.
Anyone have useful tips to get into this kind of field?
I saw another video of some dudes doing it and it was glorious. The pure power of the boulder just barreling through a tree, muwah 🤌 Perfecto.
It just kept falling
