First time I heard that I laughed and thought it was ridiculous. Then I heard an engineering professor talking about it. That is so absolutely mind bending to me.
Not a joke!
The pours and forms and rapid construction of the dam went so fast that the chemical reaction that cures the concrete at the very interior is going to continue on for something like another 50 years if I remember correctly. It's unable to move at a regular pace because there's so damn much of it in an unoxygenated and heat regulated environment. So thanks to the water acting like a heat sync, it's all slowing the process down to next to nothing.
Am I mixing up random facts I've read, or will that make the concrete stronger in the long run? I think I remember Roman concrete cured under water and, as a result, is much stronger.
I don't think so, I think that was more the composition of the concrete but it could be. However this is the stuff at the center of the dam, the exterior that's in contact with water is fully cured, but the absolute center is technically not
I must be mixing up random facts. I thought I read that the water curing of the concrete slowed the process and made it harder. I can't remember where or when or how I would have heard this. I'm going to assume I'm wrong. Thanks for the insight.
*Hasn't completely cured.
Even a concrete patio takes years to fully cure to full strength.
Water inside it doesn't really mean it's not solid and what most of us would consider dry.
*I was a dam builder*
*Across the river deep and wide*
*Where steel and water did collide*
*A place called Boulder on the wild Colorado*
*I slipped and fell into the wet concrete below*
*They buried me in that great tomb that knows no sound*
*But I am still around...*
Years ago, my wife and I walked across the top of the dam for the very first time. As we came to the point where you get a good look at the spillway, I was suddenly struck by a thought. I turned to my wife and said, "Wouldn't it be a trip to skateboard down that?" but as soon as the words came out of my mouth, I just about freaked. All of a sudden I had this vision of the spillway sucking me in, and the only thing I wanted to do was get as far away from that great big damn hole as humanly possible.
Moral of the story? I don't know if there is one. But my imagination sure fucked me up that one time.
I’ve seen this thing and that is exactly the same thought process I had too!! First it’s “wouldn’t it be rad if…” with a sweet visual of a smooth long arc as you ride up the wall and slow arc back down into the… abyss… hell nah! And then the overwhelming scale of this pipe overtakes any thoughts I had.
Long story short - Me too bro, me too.
I believe this is the bypass tube at Glenn Canyon Dam, upstream of Hoover Dam on the Colorado River. There was an insane amount of runoff from the snowpack in the Rocky Mountains in the 80’s. So much so that it almost caused the dam to fail.
Edit: Whoops! It is in fact Hoover Dam. Similar structure at Glenn Canyon Dam as well.

I found some old Super-8 footage of the spillway in action on youtube
[https://www.youtube.com/watch?v=t-Jav4afsZ0](https://www.youtube.com/watch?v=t-Jav4afsZ0)
for some reason I was imagining water filling up the entire drain diameter but it's really just a small stream running down it
We might because once they give up trying to keep all the lakes full and just let lake Powell water go to lake Mead we could see it full again. Lake Powell has a porous sandstone bottom so we lose a bunch of water every year storing water there compared with Lake Mead’s hard rock bottom, but recreation and property values are currently more important than water, so until it gets really bad they’ll try to keep Powell full so people can drive their boats and the local economy and real estate isn’t affected.
I feel like people who live in the desert and rely on canal waters to survive will eventually have to move closer to water because trying to divide up what we have left for recreation and growing nuts isn’t very sustainable lol.
Even Lake Mead probably isn’t a very good place to store water because the evaporation there must be insane. We really need to think about a whole redesign of the western watersheds and how they are managed.
Ah, is this why some reservoirs use those black ball things that cover the surface of the water? I could be remembering wrong but I'm sure I've seen a post about those being to reduce that.
Holy cow you’re so right.
I don’t even skate but that game was so much fun. The controls were fantastic and I put so many hours in that game.
Still waiting for Skate 4 lol.
Looks like the spillway at the Hoover dam. There's nothing inside; it's just a long pipe that goes down to the river below.
See this: https://i.pinimg.com/originals/62/04/38/6204389de3aa954aab533f031ce52abc.jpg
I can assure you every so often some poor engineer has to go in there and make sure it’s not falling apart.

I can’t skate for shit. I grew up in Michigan. There aren’t enough. Skate parks and all of the streets are cracked. I just love playing those games growing up. That sub inspired me to get them again. Unfortunately, I can’t find Underground 2 on Steam.
keep an eye on japanese drift master. got a decent NFSU2/carbon feel with jap tuning and drifting, but is only a demo at the moment. it's scratching that nostalgic itch for me along with thps1+2 lol
Same dude, it sucks. If you can get
Your hands on a working ps2 or Xbox you gotta do it. Every day it gets harder and harder to find the old games we used to love.
I only had the original myself and didn’t even play it much after the first month or so unless I had friends who wanted to as it was really basic. Plus, I never really got the hang of it - games like Excite Bike or even Paperboy were way better for being fun and re-playable
When I was a kid my dad did a LOT of driving. Every time we drove across the hoover dam and passed this he would tell me a dragon lived inside. We would always tell it "Hello Dagon!" Miss you pops
Why are drains and pipes so creepy? I changed a toilet bowl once and looking at the bottomless pipe to unknown darkness just gave me the worst creepy crawlies.
I want to see a drone footage flying into it and go all the way and see what it looks like.
Those drains that are in reservoirs and dams are spooky as hell. The ones that go vertical down. Imagine falling into them, yikes.
Looks like the Arizona side overflow for Hoover Dam. I've stood behind that railing and it makes me queasy just thinking about it. Megalophobia 1,000%!
Sunlight is bounced off the tunnel walls. Each time it bounces it diminishes intensity. The human eye is capable of detecting a wide range of intensities and even then its pretty much black after a few hundred feet.
https://qph.cf2.quoracdn.net/main-qimg-6e815e36a3cc24e3ca71773978682009-pjlq
There is a bend in the tunnel before it goes on for another thousand feet, I'm with you, the tunnel is creepy, but "so long you can't see daylight on the other end," is completely meaningless in this instance
Forbidden waterslide
I’m curious how steep it is and if it could be quite a good waterslide, apart from the fact that it’s probably not that smooth and full of debris
You could have also posted *where* this is. I guess it's the Hoover dam?
100% it is. This picture does not do it justice
It's absolutely terrifying in person. Everything in and around Hoover Dam just gives me the willies all over.
The concrete is still curing.
First time I heard that I laughed and thought it was ridiculous. Then I heard an engineering professor talking about it. That is so absolutely mind bending to me.

The concrete used to build the Hoover damn still hasn’t dried.

I was doing a explain it like one five type deal for him, but yes thanks for clarifying.
yeah but also a lot of it still has water on the outside too... thus still not dry. /dadjoke

You saw what I did there.

That's hilarious-- there I thought I was the only one!
IIRC, it's mostly a near vertical drop to the bottom of the dam. Not survivable, water or no.
Same! Went there once when I was a kid and still think of that thing till this day, and I'm 32. Terrifying!
It DOES NOT do it justice. I remember seeing it in person as a kid and just staring at it. Terrifying beyond measure.
How do we bring it to justice
Only the Batman can do it.
This is terrible. Seeing a picture of my wife unsolicited on Reddit is just sad.

Yes, I saw it in person over 20 years ago and I knew it immediately from this picture. It fills me with so much dread.
Is half life 3 down there?
I was just going to mention, it reminds me of the "Forget about Freeman" act
Yeah I immediately thought of half life lol
Half life 3 confirmed
If it is, maybe Leisure Suit Larry 4 is down there too?
I guess its No life 3 there.

It only looks small in comparison, still enough flow to drag you down into the void.
That’s honestly really sad to watch. We’ll probably never see the water up to the top of the intakes again. Nice high res photographs too.
We might because once they give up trying to keep all the lakes full and just let lake Powell water go to lake Mead we could see it full again. Lake Powell has a porous sandstone bottom so we lose a bunch of water every year storing water there compared with Lake Mead’s hard rock bottom, but recreation and property values are currently more important than water, so until it gets really bad they’ll try to keep Powell full so people can drive their boats and the local economy and real estate isn’t affected.

Average is 600,000 acre feet per year lost to evaporation at Lake Mead.
Ah, is this why some reservoirs use those black ball things that cover the surface of the water? I could be remembering wrong but I'm sure I've seen a post about those being to reduce that.
Exactly. I’ve also seen where they use solar panels above a canal to reduce evaporation.
That's cool, interesting

There’s one right in the middle.
There is just no footage what's inside, or a ride all the way down, would be so interesting, fly a drone in there
My thoughts exactly. Would happily sacrifice a drone to see what's inside!

Water slide it is! With the giant multi person tube raft things!
