Last summer I visited Rusper brick works, a quarry where my father worked as a very young man. It is now a lake, so I took a swim. I was floating above where my father had worked. Now He is floating above me.

The thing that blows my mind is that water can easily cover up a whole nother world u would never expect the stuff you see down there

I noticed the 'No Smoking' sign in that tunnel. Obviously smoking is dangerous even under water.

Best inland UK quarry by far. I've done about 400 dive in this quarry from the nineties to a couple of year back, and the best viz was at the end of January one year when me and my buddy were at 48mtrs near the Pinnicles and we could see the surface buoys and the sun highlighting them and the rope. Used to pop down Henry's ridge and then over the the 48 hut, on the way to the submerged trees in the far corner; this was just one of my favourites and all free. Many happy days, but some sad one too.

@9:15 i"m thinking, "What strange looking feet!" Then, the camera surfaces and it's a dog. lol

"1994-2004, 21 divers lost their lives in the quarry." RIP. Great video, this location is obviously for higher experienced divers. Would love to learn to dive.

Just what I'd expect to see in an old quarry, excellent video.

1:55 - There's my keyboard! I've been looking for that damn thing everywhere...

incredible footage guys, fascinating stuff!

Thank you the tour! This was awesome.

Thanks for a trip into a world I'd never get to see. Awesome!

I love it. Very fun to watch while we’re stuck at home ❤️

This is awesome I regularly swim in Dorothea and it's nice to know what's below you 😂😂

The simplicity of elevator music is that it masks (pun?) the many video/audio cuts required for a smooth story. Thank you 50mPlus.

I love the music choice so much

Thank You so much for sharing! 😱 I must commend you on your Bravery! It’s literally a another world 🌎 deep beneath the quarry! A shame to see so much clutter and cars. Have they ever considered cleaning up the bottom of the quarries? Great 👍 Video.

Wow this is really awesome!! Cool as hell seeing that little shack with fireplace 🤜

One of the best diver vids I have watched. In my younger day, I bounced 75mtr on compressed air. I just wish I was still diving when mixed gas entered the main diving stream. I would have loved to view more technical information about the dive

It's amazing how the clarity gets better the deeper you go

Man that's deep. This was a top shelf video. Thanks for posting it

Awesome video, really well done. I enjoyed it from beginning to end.

I live very close to here, and it was only recently I managed to walk on the footpaths and get close to the lake itself. Absolutely amazed at the footage you got, very interesting indeed. Must be a surreal experience. Great Work.

7:25 says 2005 on the right side Carved into the rock

This quarry had the last Cornish beam engine ever produced here in Cornwall. Guessing not much left of it now? Great video, really enjoyed that. Sending warm wishes from Cornwall.

I'm guessing by the adits and winch that this was also a mine as well as an open pit slate quarry. That was a cool little shack! I think the oddest thing was the BBQ and chairs that have apparently been there since sometime between the time the quarry shut down in 1970, the pumps were shut off, and since it is lower than the natural water table it filled with water. Glad you guys came out safe; between 1994 - 2004 21 divers lost their lives in that quarry.

Brilliant video.

Great video and dive. Would love to see footage of Ft. Dickerson Quarry in Knoxville, TN. Great visibility there too.

Beautifully shot : )

a very good friend of mine and previous diving buddy from the mid 1990s lost his life there 20 years ago ..made me think hard about adrenaline sports and I gave up my climbing and deep diving shortly after ..I miss the ability to drift in space and the tinned buzz of pressure on ears and brain..but I don't want to do it again Now I would be forcing myself to do it to prove something to myself and I like life too much..it's weird seeing Dorothea again it's just the same as it was 25 years ago..only I never got down to 104metres..so these guys have had a proper grumage ..the water looks pretty good tbh and visibility seems somewhat better than how I remember it.. Anyway nice vid and be careful

great video, loved it

Idk, but watching this I'm terrified. My breath suddenly fast paced.

I love diving dotty. Never been that deep though!!!!

Great videos, my son dives in this quarry 👍

Amazing video! After the cave rescue in Thailand I have a new respect for cave divers and the risks they take

Great Footage! Nice Dive! 👍 👍!

Awesome video, it feels like this place flooded over night with some of these findings. But on the other hand a couple of those cars were very old models. I saw graffiti from 2005 but at the same time there was a house that looked from the Stone Age haha great video!

Awesome video! Once my goals is to do a similar dive. VERY COOL!

Very entertaining dive, well done, a great team there, good entertainment thank you for the great upload. regards from Paladon.

Cool, thanks for sharing.

Wow thank you for sharing 👍

That Escort Mk1 could be worth saving.

great vid. Hope Dotty stays open...

I’m sure you know you thing perfectly but just be carefull guys! You’re content is bloody amazing!

Great footage.

When you dive, neutral buoyancy makes you feel as though you're flying, particularly when the ground gives way below you and you're there...drifting.

visibility is amazing...

Really good filming !

Amazing video 👍👍 .

Thanks guys, very interesting

This is a Smoke Free Building...

Hi, If you are ever in the area to dive again, we've just opened up a new hostel down the road from Dorothea called Basecamp Wales, about 2 miles down the road in Llanllyfni

Wow you guys have a real sense of adventure. I'd be too afraid to enter that cave under water.

muy buena edicion !! se ve muy nitido !!!

i worked in quarries like this for many years and ive fished alkot of them also. ive never seen a mature flooded quarry with this much structure so devoid of fish. quarries are fish heaven

Thanks for uploading this! I am running an RPG and I'm about to send my players diving in a quarry (with a scary monster at the bottom, of course...). This gives me so much inspiration to describe the scenes for them!

this looks hell-a-fun

Great video 😊 You wouldn't want to do that dive OC now with the price of helium.... Bad enough 8 years ago!!!

Curious as to your dive tables and mix. Nicely done!

You should take a sample of the milky stuff on the bottom. It has to have a specific gravity of greater than 1.0 witch makes it heavier than water so it stays at the bottom and do the same with the black stuff on the cabin floor. You might not want to dive there after that.

Used to see Keith, Graham and Tracy etc a lot at Dorothea 😁

Hey man start doing this again! Come to Fort Dickerson Quarry in Knoxville Tennessee

Lindissima

2:42 bottom left looks like the hand of a corpse ....creepy

There is a quarry in Ohio called Gilboa that offers scuba diving. Really neat stuff

This is the coolest fucking vid I’ve seen in a long time thanks for posting

Great dive guys ! Which Trimix mix did you used on the bottom gas of the O.C. ? My max dive was 62 meters. One day I´ll get there... Congrats !

Awesome video. Really made me feel like I was there and. I'm a diver. I wonder what that black/dark stuff is on the floor of the stone shack. Looks like a heavy liquid of some kind.

Thanks for the memory regularly dived here mid 80s Is the sign with skull and cross bones saying warning divers have died here still on the entrance to a cave

I saw a video discussing all of the diving-related deaths at the quarry but it didn't have any dive footage of the quarry. Seeing this, I kinda understand why lots of divers go to the quarry.

Wicked interesting video!

That is so awesome!! I would not mind the extra training and proper use of equipment, but does it have to be freezing?!

Great video, although I’d never dive a cave. What was your dive table and mix?

amazing

Great footage! I'd love to do this one day. I was wondering if you knew the history of it because it looks like it was flooded? And there seems to be a few cars there. Im not sure

This is fascinating..Its like as if there was life there 100 years ago

4:50 what an amazing looking building, that stonework is great. Too bad it's so far underwater.

What was your bottom time and deco stops in total at what depths? Thanks

That kind of diving takes _insane_ amounts of guts...

They should do movie scenes in this place - wild!

350+ ft?! You are an absolute mad man with balls of titanium!

Helluva dive and quarry

Brilliant video, nice camera angles, I have no idea how you can look so fresh after carrying 5 cylinders up the hill.

8:31 that setup there, is perfect for fishing :))))

Would love to do this.....just curious, how do you remember your way out?

Amazing video. What was buried deep in the mining?

Old house with stove just chillin underwater.

02:17 No smoking here guys :D Super clear water...Amazing!

Fearsome place, you have to be on your best technical game, when you dive here

Incredible - but I can’t do that - but enjoy watching it, be safe.

how did that stone building end up below the water?

Thats some serious diving, I dived here once and nearly died at 50m my shit gear froze up, emergency accent was fun!

What happens if the mud gets stirred up and you can't see while you are in there?

Water gnome says "This is a smoke free building" :D

90m quarry bloody hell!

Cool video 👍

That quarry must have filled up quite fast, to have signs, especially no smoking, in that good of condition deep underwater.

Some Beautiful Dive, is the Quarry still in operation??

8:12 looks like an Mitsubishi EVO IV in the lake. Wonder how it ended up there

Now this is going into the abyss!!

great footage, miss dive here,
