... you were graced by the ghost that left you the Emerson Company bottle. That could be the key to this mystery. This may not be an Emerson-owned distillation-site... but this most-likely is a late 1800's to early 1900's chemical-distillation complex. Judging by the bolted-flange on that junction near the coal-fired boiler-pit... it functioned into the early-1900's. This site would have featured a coal-fired boiler braced on concrete-ledges in the lower-bulk of the pit you discovered at the beginning of your exploration. Below this (now submerged) would have been another chamber for first-stage of boiler-tubing, and just below that... the "stoking-deck". This deck will most-likely still be accessible on the other-side of the boiler-pit-wall you were unable to journey into. Additionally, on the other-side of that wall, you might see the "distribution-header" for supply-side steam. Each branch from the header should have, from this location, traveled above-ground into the factory-proper (while it still existed) and into the individual flocculation-vats. Here... a chemical-precipitate like Anhydrous-Sodium-Bromide would have been stirred, flocculated and harvested. The chambers you saw below this would have been access to flloor-board mounted "steam-condensate" capture piping (the lower-intersection you eventually traveled into) and "steam-recycling" piping, which would have junctioned at the old gate-assemly you were sitting-on near the lip of the boiler-pit. It's a truly wonderful find. This facility would have likely seen, experienced and grown with the radical-pace of boiler-evolution during that period... most-likey abandoning those tunnels at the turn-of-the-century as steam-rectification, re-heating and recycling-processes were perfected. Just about the time that the Vilter Company would rise to dominance in this field. A field that Emerson (no-longer just a drug-manufacturer) now dominates... as it owns Vilter and many-other industrial and electronics subsidiaries... as one of the largest industrial-process manufacturers in the world. I have specified and worked with... many of their products and people over-the-years in my line of engineering. Thank-you for shining your light down these old lost-corridors of American History. They should never be forgotten...

Like this now, was in one 30 ago. But my grandad told me that in them where machine shops and the usually used for moving pit pony’s and designed for moving around a plant or mine whilst still accustomed to the dim of the mine. If you want I think I can find a picture of the plym entrance , and the run through , just be careful of marsh damp. It’s a killer. .

i dont think a horse is fitting there man.. Tbh i believe this guy hes an engine says he has blueprints of a struggling like it heres his 1st post @trikk9964 1 month ago ... I was just thinking about one-other very-interesting aspect of this design that rivals modem-engineering in-terms of net-efficiency... and deserves enormous-respect in-regards to the initial designers: this "steam-recycle" tunnel was designed to work in conjunction with waste-heat from the boiler to provide "counter-flow" heat-regeneration. Conductive and convective waste-heat just pouring-off the uninsulated main-body of that boiler would have been funneled down the "recycling" tunnel... almost like a furnace air-stream for this unique purpose (this explains the combusted-debris trail within that refractive-conduit). The recycled-steam returning from the heat-exchangers located within the upstair-vats would have then been re-heated and re-pressurized within this piping-section to an ideal "approach-temperature" before returning to the recycling-section within the boiler, while also keeping the "condensate-capture" lines quite-dry. This would have resulted in two major performance-factors. One: boiler efficiency would have risen 10-15%... rivaling modern side-port injection-techniques. And two... this additional warm and dry-air movement would have contributed to incredible longevity of the subterranean steam-piping by limiting condensation-corrosion through extreme temperature-cycling; something that insulation during those time-periods, other than these refractive-brick chambers, would have driven-to-failure in under a year-to-two-years. This-place... really is quite-special. It had to have been desiged by someone with exceptional-expertise. Someone like YORK Refrigeration out of PA or Vilter Company; both being known associates of Emerson. I can't imagine who-else would have understood these principles at the time of its initial-construction. Amazing-stuff, really. As a note: modern heat-exchange can take what would-have required the entire-length of this tunnel for counter-flow... and place it in something the size of a washing-machine, or smaller.

"Bromo-Seltzer was originally created in Baltimore, Maryland in 1888 by Isaac E. Emerson. The original formula contained sodium bromide and acetanilide, both of which are toxic substances. Bromide is a tranquilizer that was removed from the American market in 1975 due to its toxicity. Acetanilide is also a poisonous substance. Bromo-Seltzer was originally sold as a headache cure and hangover remedy because of its sedative effect." Wowzer! I love your sense of adventure, thanks for taking us along the journey! 🤙 Also bromine was used for fire retardant and sanitation in the early 19th and 20th century, as well as an anticonvulsant and sedative until its toxicity was later recognized.

[@CuriositiesCaptured]

Thanks for that bit of knowledge.

Bromide salts aren't really that bad as toxicity goes, the real problem has to do with impurities of bromate which is very carcinogenic.

Those look like old sewer tunnels, and the big pit with the water looks like an overflow sump, all possibly Victorian. After watching more they could be drainage tunnel for a mine, when buildings like these they usually install a tramway, and take it up when finished. I have had a second thought, do you know if there was a building above, these could have been access tunnels for a cellar for transporting coal for the boilers, the big sump could have been a condensing pond for the steam engines, where the hot water/steam is dumped to cool before reusing, that would explain the cast iron pipes

You guys have the best cave exploration videos out there! Your videos are highly, entertaining! I just started watching them! When I first started watching this video, I thought, that's the best built sewer I've ever seen, I now know what a turd feels like! But, on closer inspection, I'm pretty sure that's not a sewer! I'm asking the question, how long did it take to build that, how big is it, how much did it cost, how many bricks did it take? The number of bricks alone, is blowing my mind! I also noticed, there is no graffiti on the walls! This place is not well known! How many other places like this exist and no one knows about them? This is a great video! Thank You!

[@krulerwest-oz7364]

That brick design is old the longer and thinner the brick also the denser takes the bricks age further back. When you were crawling back at 14.16 squeezing through that partial collapse I did notice that the dirt that was falling into the tunnel was made up of coal debris and well almost clinker material. Is this area a filled in small valley of industrial process waste, these tunnels were built then fell out of use and they just piled all their waste into a depression or small valley I have seen them do that in Wales UK, they buried whole valleys even a train/ aqueduct bridges and the work village that grew up to support a mine or smelter site,

[@50bograt]

it would be interesting to check old maps to see what used to be above those tunnels...looks industrial, these could be cellar tunnels of a factory maybe pipe tunnels as at one point it looks like there were sleepers on the floor...maybe to attach pipe brackets to, the deep pit must have a drain or it would be flooded deeper than it currently is. if i knew the location i would have a nosey at old maps myself, also how deep down are the tunnels as the first tunnel is stone walled and brick arched that smacks of what we call cut and cover..ie. dig a trench build brick arch then fill in, the stone sides hints at an earlier existing structure though.

I did pest control back in the 90's and did a lot of termite treatments where you had to trench the subfloor perimeter and stumps before laying the chemical down and back filling while crawling on your stomach in areas you could only just fit.

That is an old stormwater drainage system and storage cistern. There are probably tons of artifacts down there to be found.

[@mehck-gk9yn]

that would be the smallest storage cistern of all time by far.. I don't think so.

with dirt floors 3ft wide? This guy has blueprints check his explanation @trikk9964 1 month ago ... I was just thinking about one-other very-interesting aspect of this design that rivals modem-engineering in-terms of net-efficiency... and deserves enormous-respect in-regards to the initial designers: this "steam-recycle" tunnel was designed to work in conjunction with waste-heat from the boiler to provide "counter-flow" heat-regeneration. Conductive and convective waste-heat just pouring-off the uninsulated main-body of that boiler would have been funneled down the "recycling" tunnel... almost like a furnace air-stream for this unique purpose (this explains the combusted-debris trail within that refractive-conduit). The recycled-steam returning from the heat-exchangers located within the upstair-vats would have then been re-heated and re-pressurized within this piping-section to an ideal "approach-temperature" before returning to the recycling-section within the boiler, while also keeping the "condensate-capture" lines quite-dry. This would have resulted in two major performance-factors. One: boiler efficiency would have risen 10-15%... rivaling modern side-port injection-techniques. And two... this additional warm and dry-air movement would have contributed to incredible longevity of the subterranean steam-piping by limiting condensation-corrosion through extreme temperature-cycling; something that insulation during those time-periods, other than these refractive-brick chambers, would have driven-to-failure in under a year-to-two-years. This-place... really is quite-special. It had to have been desiged by someone with exceptional-expertise. Someone like YORK Refrigeration out of PA or Vilter Company; both being known associates of Emerson. I can't imagine who-else would have understood these principles at the time of its initial-construction. Amazing-stuff, really. As a note: modern heat-exchange can take what would-have required the entire-length of this tunnel for counter-flow... and place it in something the size of a washing-machine, or smaller.

Looks like an old sewer system, There was that iron drain or sewer pipe back at the reservoir near the beginning that was added way later but keeping with the original use. It would help if you gave a lay of the land above these places and the history of the area.

Another awesome vid guys

[@outersketcher]

I got to 5:38... NOPE. NO WAY. Nuhh uhh. I can't even WATCH that. Had to fast forward. haha.. You guys are really brave/nuts!

[@MrDuffy81]

Have you guys ever experienced some weird cryptid creature down underneath the ground?

[@charlesfernatt]

If you go into Ridley Park and Prospect Park near Philadelphia there are still underground tunnels in the basements of a lot of the old houses! And they lead absolutely everywhere!

[@JackieAustin-i8d]

I hope to GOD you never have something come crashing down on you. You guys are fearless 😁.

Looks like old world red brick to me.....the folks before the last reset probably built it. Very cool (and claustrophobic)
