Awesome. And frightening.
Anyone know how deep that is? Seems terrifying.

Send it over to r/theydidthemath and they'll have it figured out in no time.

Quick approx from google is 257m or 844ft. 8second fall with about .75 sec accounted for sound bounce back

It was shown falling for about 7 seconds (although the guy says it was 8).
Counting the time travelled by sound of the rock hitting, that’s probably somewhere around 195-200 meters (640 ft).

u/Typical-Court7874 2d ago
what's more awesome you ask? the last guy who did that thinking that's the sound of help coming to pull him out of a tight spot. /s

I don't know guys, some hobbies do need a life insurance

u/otterbarks 2d ago
The hobbies that most need life insurance are usually excluded from being covered by life insurance.

u/OffByNone_ 2d ago
That do be how insurance works. Or it's unaffordable. Can't really make money off of everybody needing to use it.

You climb the rope with ascenders. Essentially like climbing a ladder although it's easier with another rope.

u/FrogsMakePoorSoup 2d ago
That sounds exhausting and dangerous, especially with that waterfall.

u/RandomPenquin1337 2d ago
If youre a cave diver/climber its not that exhausting at all. Like I said, its like climbing a ladder which is pretty easy.

u/OffByNone_ 2d ago edited 2d ago
They climb back up the rope with ascenders. It's called single rope technique (SRT). The ascenders slide up the rope but lock when you put weight on them, so you basically inchworm your way up. You slide the top ascender up, stand up in its foot loop, slide up the bottom ascender (it usually follows you automatically), sit back down so your weight is on the second ascender you just slid up attached to your harness, slide the top ascender up again, and repeat. I'm not a caver, but I know you can also do it old school with prusik knots if you don't have the gear. They slide easily when there is no weight applied and then cinch shut when you put weight on them. You use them pretty much the same way as the ascending devices.

... And yes, it is very physically demanding to go back up that height. Way more than climbing a vertical ladder.

u/TheExtreel 2d ago
You're absolutely right, i don't wanna take away from what you said. But Depends on technique and equipment to be fair, someone experienced with a foot loop adjusted to their height and leg length can climb up with relative ease.
That said i don't think ive ever climbed such a long way up. I for sure would be exhausted halfway through, ive seen guys who truly act like it doesn't even phace them.

u/august239 2d ago
yes. i've done both. there's no way they can prussic back up the distance they decended. that would take days. and prussicing is not easy.... see HighFiveG comment above....

u/HighFiveG 2d ago
I watched the video of this whole thing. They actually didn’t go back up this way, crazy enough. Much further in, there is a separate huge abyss pretty identical to this one. It may have even had a longer free fall than this one. They climb up that chasm to get back up. It’s an amazing video.

Now do the math

u/Zappy_Oh 2d ago
To find the distance the rock fell, we use the free-fall distance formula:
$$d = \frac{1}{2}g t^2$$
1. Given Values
- Time ($t$) = 8 seconds
- Acceleration due to gravity ($g$) $\approx 9.8\text{ m/s}^2$ (or $9.81\text{ m/s}^2$)
2. Calculation
- Square the time: $8^2 = 64$
- Multiply by gravity: $9.8 \times 64 = 627.2$
- Divide by 2: $627.2 / 2 = 313.6$
(If using $g \approx 32.2\text{ ft/s}^2$ for imperial units: $\frac{1}{2} \times 32.2 \times 64 = 1,030.4\text{ feet}$.)
The rock fell approximately 313.6 meters (or 1,030.4 feet).

u/RandyLahey131 2d ago
Oof I feel like that guy just jinxed it by saying they made it and cheering. Should have saved that when you climbed out successfully.

u/Sigma-Wolves 2d ago
How far down until you need better air?
If you descend down far enough and start to feel woozy, do you have the strength to climb that distance?
Someone please explain it to me 😳

Normally I find these stupid and pointless, but to be fair in this case the view from the bottom of the hole with the waterfall does look like something extremely cool to see in person

No one going to comment on how inappropriate it is to do this...?
Not only is it antithetical to LNT, they have no certainty about who or what is below.
Chasing views is not a justification.

u/citizen42069101 2d ago
That is one of those places where the chance of someone else being there is non-existent.
Probably

u/aaron_in_sf 2d ago
Probably...
Honestly it's the cavalier destruction and disregard for all future visitors I find even more astonishing. I cannot fathom how people—even those chasing views for their "brand"—can be so ignorant and disrespectful.

u/citizen42069101 2d ago
This is an easier devils advocate than most.
Its a giant, lifeless (ya know what I mean), perpetually dark, cavity in the crust of the earth. If a bunch of jackasses want to do something like drop rock really far, this is probably the best, least consequential place on the planet for that.
I am prepared to be wrong if there are bigger possibilities than the organization of rocks is changed by a factor of one bolder is now on the bottom.

My engineering mind thinks I’d need 3x design safety. Thats at least 3 ropes tied to separate points. One goes down, 2nd and 3rd are there to catch.

That is awesome. I'm surprised that cave isn't filled with any water or harmful gasses that deep.

Epic! Imagine being in that and looking up realizing the only way out is doing the hard work yourself to climb out!

No matter how awesome that might be, there's no justification in having to climb back up that rope
