Exploring the Abandoned, 3500-Foot Rosemont Tunnel (Part 2)

The exploration of the abandoned mine known as the Rosemont Tunnel continues. The tunnel plunges into the mountain and is reported to be 3500 feet long with an opening at the far end on the other side of the ridge. Here in Part 2 we reached some of the furthest reaches of the mine and found some unusual features including a dangerous bridge over a steeply inclined ore pass, an unusual cistern in a backfilled tunnel, and other things. Did we actually reach the other end of the 3500-foot long tunnel? You’ll have to watch the video to find out!

You have the best abandoned mine exploring channel in my opinion.

[@AbandonedMines11]

Thanks for your comment. Maybe not the best channel but definitely one of the longest-running here on KZbin. Hard to believe I started my channel way back in 2006. I’m definitely one of the originals - and still here!

[@adamwest8711]

Definitely. No frills, no over-dramatisation, just interesting mines and commentary.

[@AbandonedMines11]

@adamwest8711 Thanks, Adam! I appreciate the feedback. Thank you for your ongoing support and interest in my channel and videos.

[@JillianArcher]

Hey Frank! I have to say, this has been one of my favorite mines. The bridge was super scary, it gave it a horror movie vibe. I loved that. It also had a touch of mystery with the pipes. Very good video Frank! I hope to see you soon :)

[@AbandonedMines11]

Glad you enjoyed it! We were disappointed that we couldn’t reach the far end of the tunnel and exit the mountain on the other side. A major collapse was blocking the way. Based on where the collapse was, we missed about 75% of this mine. It really is extensive underground although the drifts seem to be kind of aimless and exploratory in nature. Definitely an unusual one, that’s for sure! Thanks for taking the time to watch and comment!

[@ABANDONED_UNDERGROUND]

That bridge was something, huh? I'm glad we traversed over that rubble pile to find that cistern! I really appreciate the shout-out! Thank you!

[@AbandonedMines11]

That definitely was an interesting mine even though it kind of wandered all over the place. I think it’s great that none of us six who were exploring it that day had ever been there before. How rare is that? LOL

[@ZiaMountainAdventures]

Another one down! Good edit Frank! Think we may be heading back to the one we started on Sunday this next weekend see what else we can find… on to the next adventure! 👍👍

[@AbandonedMines11]

Thanks, Todd! Yeah, there is definitely much more to see in that mine we were all at on Sunday during the recent trip. All those winzes must go somewhere! I looked that mine up in some mining reports and stuff like that which said it has several miles of underground workings - or something to that effect. It also said that all those mines in that area are basically interconnected with each other which, as you know, we found out when we squeezed through that little hole and made our way down into the neighboring mine. Will be interested to see what you guys find out there. Be safe!

[@CassioCorvis]

That bridge !! Wow . Great video Frank 👍

[@AbandonedMines11]

Thanks 👍 It’s kind of rare to find underground bridges like that. I think I’ve only seen two others during the last 15 years or so. Thanks for watching and commenting!

[@paisliesplace3921]

Wow the cistern, what a find! Very interesting to find that inside the tunnel like that. I wonder where that pipe leads to. The bridge scared me, soaked plywood over metal could be rusty underneath, you all are brave! lol This was a huge mine. Thank you Frank for taking us with you!! As always Frank, safe journeys!

[@AbandonedMines11]

Yeah, finding that cistern was pretty neat. The fact that it was in that drift tunnel that was directly behind the metal bridge at the top of that steeply inclined ore pass was interesting, too. Lots of mysteries in this mine! We only got to see a fraction of what was there because the main tunnel that goes all the way through the mountain for about 3500 feet total was blocked with a huge collapse. One of the explorers with us who had some knowledge about the mine said that we were only able to see about 15% or so of the entire thing because of that collapse which had sealed off the rest of the workings. Might have to go back and approach it from the other open end of the tunnel and see if we can get in from that side. Thanks for watching and commenting!

[@FictionalRen]

Early gang! Let's go! Part 2❤ I don't follow you for spooky stuff but I love spooky things so seeing the abandoned stuff left behind is just thrilling. Gotta say, I like that you aren't on your own going into some mines. Safety in numbers ❤

[@AbandonedMines11]

Thanks for your enthusiastic comment! Yes, sometimes when we come across this equipment deep underground, it does evoke a feeling of spookiness to a slight degree. And slight sadness. What gets me is the fact that the equipment has been sitting there underground for all those decades if not for a century, and it will never move again, either. It will always be there in the dark and quiet. I don’t know - there’s just something kind of gloomy about that, if you know what I mean.

[@FictionalRen]

@AbandonedMines11 Yes! It has a sense of mysticism about it, that it will act as a time capsule for us and all those who come later, like an echo of the past. I love history, so I'm fascinated by the traces people-long-past have left. It's a bit sad that they're gone, but it's beautiful in a way to find them in the things they did. Thanks for the new video, I'm super excited for part 3!

[@RockerRed]

I was saving this video for later viewing & forget to return until your community post about onion soup casserole. 🙂 Another great video Frank! That bridge looks scary! 👍🤘Thank you! Thank you!🤘👍🦃🧡🖤🎃🖤🧡🦃

[@AbandonedMines11]

Because that bridge was made out of metal, it was pretty sturdy. Had it been a wooden bridge, I don’t think any of us would have crossed it. The condition of that plywood decking was atrocious!

[@royjennison3916]

Epic Frank well done , stay safe

[@AbandonedMines11]

Thanks again, Roy!

[@johnsmart964]

Thank you very much for this very interesting and informative video presentation which we are most grateful for. The work that you do in providing these for us is much appreciated. The bridge could be repaired by using metal plates in place of the plywood. The plywood was never likely to have a long life, solid wood would have been better. The collapsing areas could have metal placed around the area to strengthen it, but if there are no plans to reopen the mine the work would not be necessary. The mine certainly had a good long life and had proved by its longevity to have been remunerative for the miners, maybe there would still be minerals of value when mined using current techniques.

[@AbandonedMines11]

Hey, John! Good hearing from you! Yes, a metal plate would've been a much better idea for the bridge deck. They might've used the plywood because they weren't planning on being their for a long time. Definitely was an unusual mine. Seemed very exploratory in nature with all of the extensive, wandering tunneling. Thanks for dropping by and taking the time to comment!

[@dancjr2]

Fantastic video! The bridge was definitely a surprise along with the cistern, I don’t think I’ve seen a cistern in any of your mine explorations, at least not that I can remember. You captured a lot of fantastic color variations, this was really interesting to see. Thanks for sharing, Frank, stay safe.

[@AbandonedMines11]

Yeah, that bridge was something else! That piece of plywood covering the bridge was totally soaked and rotten. It was like mush! That’s why we had to step on the metal crosspieces instead. I believe I have only seen a bridge in one other mine and that was in one of my early explorations back in 2012 or something like that. It was pretty far underground, too, and went over an extremely deep, almost vertical shaft. The cistern in this mine was the first time I’ve seen something like that in a mine. Very unique! Glad you enjoyed the video, Dan. Thanks for checking it out!

@AbandonedMines11 awesome Frank thanks 😊 🙏

[@luminoussoundsyt]

A very interesting explore frank and that bridge sure was sketchy looking .

[@AbandonedMines11]

Thanks for your comment. That bridge sure was something! It’s amazing how that piece of plywood that was placed over the bridge has become totally waterlogged and mushy. One of us did test it out by stepping on it lightly only to have his foot go all the way through it. At the very least, it was a good reminder that timbering of any sort in flooded and wet mines needs to be approached with caution. It will be compromised!

[@luminoussoundsyt]

@@AbandonedMines11 I wonder why they used plywood in a mine that would get wet cause it doesn't work well with water etc , ps it's me Alex 🤠

[@AbandonedMines11]

@@luminoussoundsyt Hey, Alex! The mine might’ve been a lot drier when it was actively being worked. But who knows? Whenever that plywood was placed across that bridge, perhaps the miners weren’t planning on using it that long. It might’ve held up for the first five or six years. But again - who knows? Always a lot of mystery whenever we’re down in these abandoned mines trying to figure things out.

[@luminoussoundsyt]

@@AbandonedMines11 yeah I completely understand frank I guess over time when it was abandoned it just rotted away, it was also cool seeing that pool with a pipe in the middle as well .

[@Zaque-TV]

Do you guys ever bring neon tape markers into the more complex tunnels? Id be worried id lose track of where i came from

[@AbandonedMines11]

Believe it or not, it’s easy to avoid getting lost in these mines. They usually are only one way in and one way out. When you start ascending and descending to other levels, then things can get problematic if you don’t make notes about the route you’ve taken. I’ve been doing this for 16 years or so, and there have only been a couple of mines where it was necessary to keep very good track of my route or risk otherwise getting hopelessly lost.

[@volitioncvrmmxcix]

im sorry seeing the grainy feed at the end just made me wonder if there was suddenly radiation but nahh..no way

[@AbandonedMines11]

When we were exiting the mine at the end of the video, I was filming with minimal lighting. When I edited the video, it was very dark so I had to turn up the brightness level or something like that in order to make the footage more visible. That caused all the graininess that you see. Sorry about that! Thanks for checking out the video, though, and taking the time to comment.

[@AnthraciteHorrorStories]

Hey man, what was the purpose of the cistern?

[@AbandonedMines11]

That’s a good question! The vertical pipe in the center of the cistern meant that it was providing water to a lower area, perhaps. But it seemed that the pipe might have been clogged because the amount of water dripping into the pool would not be enough to compensate for the outflow through the pipe. Maybe at an earlier time more water was trickling into that pool than there is now. It’s all a mystery, that’s for sure!

[@AnthraciteHorrorStories]

@@AbandonedMines11 could have silt built up into the pipe too. We have wells out here, I swap out the actual well sediment filter in the basement every 6 months or so, lots of silt, dirt, minerals build up into that. Interesting in a mine though.

[@AnthraciteHorrorStories]

@@AbandonedMines11 I had to edit all the typos in my original comment. Hahaha. I usually don't miss those! 🤪

[@AbandonedMines11]

Thanks for the possible explanation about the silt in the pipe in the cistern. Sounds plausible to me.

They sure are! This was a strange one, though, with all of the aimless tunneling that was going on. Seemed to be extremely exploratory in nature. No stopes and no ore chutes.
