My best guess would be that this belongs to Leo Brady seismic network that was installed in the 60's-70's around nevada to monitor the US nuclear tests. As there are no markings on the device itself i would guess it's either a laser interferometer (To work as a seismometer) or some kind of creep detector. In either case, cool stuff.
If you google that Hugo Benioff seismometer it says it was made in 1961-1962 and used in the early 60s for a cold war program to map earthquakes and underground nuclear explosions. I'm presuming those long tubes are laser seismometers, early ones too since lasers were only invented in 1960. According to chatgpt the earliest known laser seismometer was invented in 1963 which lines up nicely with the other seismometer, I bet that was some seriously cutting edge 1960s technology down there, only the finest for Uncle Sam lol. If those are laser seismometers they would have sent a laser down the tube, and a sensor at the other end would measure the tiny bounces of the laser caused by ground vibrations. The equipment wouldn't have given accurate data in a working mine, and a recently closed mine would have conveniently had the infrastructure to lower that stuff down safely. Fun nerdy fact I live near a modern super sized version of that laser seismometer called LIGO, they give free tours and I went to one over the summer, instead of measuring ground vibrations it measures gravitational vibrations from things like black holes, neutron stars, and white dwarfs. Gotta say that's one of the cooler mines you've featured, thanks for sharing!
I wondered if it was some sort of laser interferometry, but sure laser seismography - presumably it was much more sensitive, and better at showing movement axis.
I was doing Grade-5 Cartography in a cave when an earthquake tremor happened. It made a noise I had never heard before or since. Shaken........... but not stirred.
@@jcee2259 I bet that was scarey ...I heard a flash flood go down a different cave to the one I was in once, that was horrific...I honestly thought I was about to die. we could feel it as well as hear it ....totally monstrous feeling
I think taking a Geiger counter with you when exploring old abandoned mines in Nevada would be a good idea, especially the deep ones with Cold War era seismometers at the lowest level left behind near walled off corridors. If they didn't come back down for their expensive, cutting edge laser sensors, I bet they had a good reason for it.
Found the obituary of Matt Costello he died at his cabin, which was close by and is now gone. He died at this cabin sitting at his table, no cause of death. He was a prospector around the area for 30 years. A simple Google search will pull up what I found. He was either 59 or 60.
The The Loneliest Grave, Matt Costello was an elderly prospector who lived a life of poverty until he struck a promising claim and and sold it for $1500. Matt celebrated and had many plans on what to do with his new riches. When his friends did not see him for a few days they went looking for him. He was found dead, sitting at his table in his cabin. He was buried by his friends near the cabin although nothing remains of the cabin today.
That makes me wonder if his "friends" decided they had better plans for his new found rices that didn't have his backing!? Or perhaps his "friends" only left $1500 for looks and it had been much more! We may have us an old murder mystery.
RIP Matt Thank you for going on this series and sharing it with us. Yes, those blue/metallic instruments were labelled seismometers but I am not quite convinced that those glass pipes are seismometers. Maybe a form of piezoelectric sensor in huge dimensions? The seismometers don’t seem to be connected to the other equipment, maybe they have a paper recorder inside the housing. The pipes also remind me of those used for incandescent lighting or measuring a potential. Could they be used to measure ionising radiation if filled with a gas or less than nothing (vacuum)? Not going to send you down there again, perhaps other stations have been recorded elsewhere. Interesting! Happy New Year!
Did anyone notice a date on the instruments or the electrical installation? To me it appears to be post 1950 but pre 1980. Numerous interesting scientific reports are listed in this publication, next to the curve of graph itself they were interested in other factors like measurable frequencies and velocity and vibrations due to mining and similar things. files.dep.state.pa.us/Mining/BureauOfMiningPrograms/BMPPortalFiles/Blasting_Research_Papers/USBM/RI%205968%20Estimating%20Damages%20to%20Residences.pdf
Highly likely the contraption with the glass pipes was set in motion and physical events could be measured as a differential to a known state. In those days what they had used more AC electromechanical components and the information they were after was measured using comparative measurement principles. Anyone can find the many documents about earth movements or seismometers in mines etc. pp.
The chamber appeared to have been well insulated too. Could even have been kept within a defined temperature range too. That rod may have been something like a sound fork that was kept moving in certain directions and the energy required to do so measured and interpreted. That it was an analog value they were interested in can be deduced from the hi gain amplifier in one of the boxes where that white pipe ends.
Thank you for sharing your, obviously, extensive technical knowledge on the equipment in this mine... It was very interesting reading what you wrote. And thank you as well for your ongoing presence on this channel. You've been with us for a while.
This location had a bit of everything. I can't believe people tried to steal an ore cart! Hope you rested up well after this amazing series. Happy New Year to you, your buddies and family.
Fascinating stuff, and glad to see someone already figured out the equipment in the time it took me to click the notification. A shame about the ore car stealing attempt and resulting damage, they must have given themselves quite the scare to just leave their stuff in place and pack up. Happy new year, I wish you safe exploring and even more awesome discoveries.
Happy '25. An interesting find. I always wonder given the expense of production, transportation and installation, how long systems like these ran before policies or people changed. Hopefully long enough to have fed through some useful results.
11:00 It's a laser interferometer, pretty simple if you think about it in broad terms. Shoot a laser down a tube at a target, watch the reflection coming back. Location and timing tell you how the target was moving as the reflected beam jitters around. That's... pretty much it. These look direct though, just watching the beam at the target end.
Thanks for all your hard & diligent work in historical research LIDAR maps and boots on the ground on location exploration and filming and endless hours editing !!! Jason! 👍👍👍👍 Thank you!!! Very much appreciated by me and many out there. 🏆 As The Most informative in depth and interesting Mine Exploring footage out there!!! Always looking to see if I recognize any of the places you’ve been in California . But, Nevada is still a open book & mystery for me > with endless miles of mining ! history in the most remote areas… Be safe and very best of luck in 2025!
Excellent videos keep up the good work and stay save. One question for you.seems like there's allways quartz left when there done mining why didn't they take all the quartz.?
"Deep in old mines, scientists primarily conduct experiments related to particle physics, studying elusive particles like neutrinos and dark matter, as the deep rock shielding protects the sensitive detectors from cosmic radiation that interferes with measurements on the surface" My dad's a pretty famous physicist, so that came to mind. The earth acts as shielding - but some stuff (neutrinos) don't interact with matter, so they shoot right thru all the rock. The best neutrino detector is deep in the ice at South Pole station, Antarctica.
Interesting “In old mines, seismographs are used for monitoring seismic activity, which means they detect and record vibrations caused by rock movements, allowing miners to identify potential instability risks like rock bursts or cave-ins, enabling preventative measures to be taken before a major incident occurs; essentially acting as an early warning system to ensure mine safety.” Probably used before OSHA which was passed by Congress on April 28, 1971 or the The Federal Mine Safety and Health Act of 1977, also known as the Mine Act, is a law that governs the safety and health of miners in the United States
Matt got the bejeezus kicked out of him for tinkering with those kids science project so you better hit the road if you know what's good for you. Love your videos and don't let anyone scare you off.
I began organized exploration in 1964 with the National Speleological Society. Qualified for life membership with the Wyoming NSS for what I did under Montana, Caves are not man-made and have no light. Mine issues involve the people that make them. My cartography shows what a cave is doing.

I want to make a joke about the Wong herb company but I best not (advert in the paper) That ore cart must have made a hell of a noise , what a mess. I am surprised at how well it survive the fall though it certainly was well built. Not sure about the time machine but it looks a lot like a laser vibration detector to me, seismometer based but ultra sensitive Fire the laser down a tube to a mirror then measure the deflection in almost photon accuracy....probably not that accurate then to be honest but certainly they are now.
That science experiment may be an early detector for detecting cosmic radiation, a similar experiment was carried out in one of the deep mines here in the UK, some particles from deep space can only be detected in deep mines as they are the only particle that can pass right through the earth.
Never. I've been in over a thousand abandoned mines and have never encountered either of those. Methane and black damp are almost exclusively found in coal mines.
It seems almost odd that someone tried steeling a cart, but left large amounts of, I would guess copper wiring if $$ was the idea, as a cart would be easily identified as mine theft and isn't it law in Nevada that protects old mines as historic?

And they'd probably only work for underground or surface tests (more specifically, those which result in the release of energy having direct co tact with the earth) that far underground.
That crossed my mind as well, but I don't think so. The arrays they use to do that sort of thing are usually both quite enormous, and significantly deep underground, or better yet, under ice. I could easily be wrong, but my gut tells me it's seismology related, as Justin theorized.

Yep, the instruments and general installation look like what I‘d expect from then.
Those glass rods could be tilt meters, they are still in use today.
Perhaps an invar strain meter?
Those I found look very similar to those glass (quartz?) pipes along the floor.
@@-r-495 Yeah i think you are right, Quartzpipe strain meters look almost to a T like these things.
It is a neutrino detector

I used a handy dandy inflation calculator and that $1500 in 1926 would be equal to $26,736.69 in today's money.
@alanscott3999 Would that calculator be set on loaves of bread or gold or cost of living or bottles of beer?

Super cool mine. All the timber and wood products down there is amazing. Getting it all down there and constructed. Must of been a rich mine
Another great video series comes to an end! Thanks for doing and documenting what we all wish WE could do!
Thank you! I'm glad you enjoyed the series.

Excellent videos keep up the good work and stay save. One question for you.seems like there's allways quartz left when there done mining why didn't they take all the quartz.?
Quartz doesn't always contain valuable minerals. Sometimes it is barren. That's why sampling and assaying is so important.

Definitely a seismic sensor.
Remember Duck Tracy's wrist tv, communication device ? They have those now.
Interferometry? Just thinking about the angles it’s at.
Happy New year my friends
Ocassionally when you are in a mine and its quiet I hear what sounds like a fan or aquarium pump... Is this cooling fans for your lighting?
Gimbal motors most like.
Happy New Year! that's probably a seismic sensor, but it might be a Tesla Oscillator made to look like a sensor. :)
