Indeed. And I think both have their place. The handheld is great for a quick run-through of an area (finding areas that might warrant a more detailed look), and for using in ways that the big unit can't be easily used (in fact, the rappelling down the Jefferson Chimney may not be necessary - depending on how straight it is, and how resilient the small unit is to the odd bump, it could theoretically be lowered down on its own, saving the risk of people using climbing equipment to achieve the same result). But in areas of specific interest, there is no contest - the detail offered makes it absolutely worthwhile to take ~30X longer to scan. I was absolutely blown away by how good it looked, and major kudos to Prof. Courtemanche and his team for creating what is, in effect, a sublime historical artifact.
I really liked seeing several solutions and several teams. That said, there could have been a little more explanation on the different techniques like you just did. Because in the video it seems like the first team was less efficient than the other when in the end they just wanted to achieve two different results. Maybe it's just an impression I had or it's the fact that I come from Quebec and I want us to look good! haha
@@VoIcanomanif they used an more recent or generally faster/better Laserscanner, like the Leica RTC360, the difference wouldn’t be that great either. Rather 5x than 30x

@@DaClaptain I'd think of it more in terms of preservation. Not everyone has the ability to travel across the country / world to experience every single thing this planet has to offer in person, and it will only ever exist in its current form for a (relatively) brief period of time. To capture a place in a moment in time, in as many ways as that felt experience can be expressed, is the ultimate goal. To have that experience available to all those who come after us is the holy Grail of preservation.
There's a scene in Prometheus where they send drones in to map out the alien cavern system and transmit live data about the internal structure, and I immediately thought of the guys from Corridor Crew mapping out the Cerro Gordo mines. "If only they could attach the lidar system to a drone, we'd have this technology today." Lo and behold, here it is.

It's more than just a single drone and mapping that are on the table. Just a snippet from an interview: "The large-scale evaluations of the autonomous drone robots at the LKAB mine starts with the operator using a user-friendly interface to notify the three autonomous robots that inspections of gas levels at various locations in the mine are required. The autonomous central system then calculates the most efficient way of going about the work. It considers which robot should go to which point and measure the gas level, how it should navigate its way there, and then report completion of its task. All this is done in real time and by fully autonomous robots in a previously unknown, complex 3D environment with no GPS structure." There are a lot of use of drones in the mines and not just in research projects like this one. Going to save a lot of lives for sure. And money.
Well to start with - I almost passed out when you said been there over 4 yrs, I remember watching your 1st vid and thinking wow what a cool thing to do buying a mine and ghost town! I can't get over it's been 4 plus yrs.. But saying that you've done an amazing job at bring what life was life back then to us and also keeping that town alive and keeping it a part of the future to enjoy.. Amazing work mate !! And now scanning the mines is using future technology to show what it really like down in the depths of that mine and its' past.. Keep up amazing work Bret !!
@@coxyofnewp I am just reading Brent’s book and got to the description of his drive up that road the year he moved there. He is a great story teller! It feels like you are there with him!!
I started following Brent just after the Hotel fire, maybe 3-4 months after and being able to see a 3D rendering of the mine is mind blowing on so many levels!
@@rafall1118 this literally is remote sensing. how "boring" it is depends on the projects you get to work on, and what field you're in. I've been doing lidar for almost 20 years, and now i'm starting to look into the drone 3D mapping (more of a phodar) for small projects. There are dozens of directions you can take it!
I could see how the drone going down the jefferson Chimney could help unlock where it connects in to the rest of the system. I know you already were able to do to some of the connection. But to be able to send down the drone without risking lives is a game changer. If only they had a drone with tank treads that could be sent through small gaps or collapts.
They would have to make it as a drone in 2 units for safety foward lidar drone and have it tethered to a back up tow drone in case the first drone accidently drove off a ledge into a chute or got stuck.
most drones rely on connections like GPS, bluetooth, wifi, etc. these won't work through dense rock, so unless it's a straight shot it would be problematic. one on tracks would be neat. just a gopro attached to a vehicle of some sort... though you still need that connection to work to the controller.
Huge thanks to Bishops' University and Leica for taking so much time to map such a wonderful piece of history - preserving it for the rest of us. This video truly does illustrate the places where the technology shines - and where the technology needs to be improved. What an excellent learning experience for the students (my assumption). Although my field was different, going on trips with teachers and professors to things relating to my major were always memories that stuck around. Again - great job and thanks to all involved!
Another Home Run show, I know that all of us ,now speaking for everyone who follows you, Great job again, just keep them coming and we will keep watching and living thru these shows
As a IT nerd and co-owner of The Mahoney Mine, it would be pretty easy - and informative - to be able to compile and release a 3d walk through on Quest or Playstation 3D. Not to mention lucrative. Reach out to us!

@@JamesBuddell-fn6bz OP wasn't taking credit for giving the channel the idea, just expressing gratification that a thing he suggested has become a reality. I'm sure all the owners of VR headsets subscribed to this channel have had the same thought independently, and I'm sure many of them have made the suggestion in the comments. I myself left a comment on one of his videos some years ago that he should try to get in touch with someone from Epic Games to come out and do photogrammetry and LIDAR scans to recreate Cerro Gordo in Unreal Engine for a VR experience. I would imagine the channel probably gets a couple dozen such comments on every video it uploads.
The fact that you are sharing all the data is awesome...in no time someone will have 3D printed the entire thing in sections that you can open and explore from the comfort of your museum room. Thank you to all who were involved.
What a great team and dept!! Its amazing what this technology can give you and us as a viewer. So awesome to have such a willing group come out and spend time working on it!!
Slightly different tools, the LiDAR will give sub-mm precise measurements of the whole space, the Leica scanner will give you the general shape of the space quickly.
@@Ammoniummetavanadate Is that type of high resolution LiDAR over kill for this application? I think the trade-off between speed or accuracy favors the Leica system.
@@259Den3 Really depends on what you want to do with the data. If you are detecting say movement in the rock in certain areas over time that might absolutely be needed. Or if you want very accurate three dimensional positioning data.
I’m so glad you’re still sharing your dream with us. These videos are amazing. I do worry when you’re off hiking alone but you have such beautiful views of the valley and mountains
Brent: This is something new to me. Very excited to see the outcome of the 3D mapping. Bringing your history to life. Thank you for another amazing video. Keep up the great work. Now I can't wait for your American Hotel to reopen. Regards 🇿🇦.
What a cool project, always a treat to get an update, but this one was wild! Those little scanners are nuts, the maps are such an invaluable advancement in safety and opens so many possibilities for future cave mapping!
This is so fascinating! The deeper level's size being totally wrong in estimation is definitely a testament to how big mines can get and like how a dark winding corridor can really mess with your senses, smaller areas just feel smaller overall when they are really much bigger! It would be cool to get some crawling drones in there to transmit to each other in a kind of mesh network to scan other parts of the mine which are not as safe for people to go to, or maybe like the radar that oil drillers use to look for oil.
I can easily imagine researchers a 100 years from now being so thankful this dataset exists. Taking new mapping and comparing to the old one, seeing how the mine evolved and moved over the centuries.
Brent!!!!!!! Hello right back at you buddy.. I've been here since u started your journey from Texas. I got to say I'm proud of you. I hope the fur babies are good I never see him anymore. Stay safe, stay intrigued, stay spooky..💜
You saying that you may be able to make a new portal into the mine with this data at the 5:20 mark makes me happy for you and also take me back to a few videos ago where I asked if such a thing would ever be possible. :)
When I was a kid we went down into a shaft mine and I got turned around (AKA Lost). Totally terrified. lol Seeing you guys down there makes my hands sweat, but it is so entirely cool I can't help but watch.
When in high school 2 of us went into the asbestos mines in Benicia and while wandering round with our flashlights, we found a vertical shaft. Soon voices from down the shaft implored us to shine light down the shaft till these 3 college students found a way up 3 layers. They were grateful
You can see the significantly lower quality of the Leica handheld. It's obviously much faster though, so if the accuracy is enough it might be just right for your purposes. That said, from a historical-preservation perspective, the high resolution is fascinating as it shows so much more detail in the mining techniques etc. and is more usable for a full VR application or similar.
They should take a combined approach. Brent needs the fast data to try and get around the collapses, while we need the high-accuracy scan for preservation purposes.
Awesome . Can't wait to watch. Keep doing a good job Bruvver. I'm in SE B.C. and been a prospector for 24 yrs. I've watched you from day 1 I'll get a passport and come see Cerro Gordo 1 day soon I hope. I can drive truck and run equipment especially 🔨 and Shovel 🍻
This is really exciting to see! Congratulations for making it happen, and as always, your work and vibe are much appreciated by those of us living vicariously😊
I really enjoy watching and listening about the history of Cerro Gordo and now seeing the 3D map of the Union Mine is really great thanks and have a great weekend Thank You.🤠👍🇺🇲
Having that cell tower right there, guaranteeing access to communication, is a huge safety feature too. If you could lay a hard line (or a series of routers) from deep inside the mine to a router with access to the tower that would be huge too.
I'm thrilled to see a move in a similar vein (always intend your puns, everybody) from the work done when the (iirc) CC folks went up to Cerro Gordo. These maps alone would be an amazing thrill to explore around. The wide ranging possibilities for work like this asked me. Someone working as an historian, creating a history book of this mine system, with links in a digital edition that take the reader to the exact locations relevant to the account. Or using scans like this to put a realistic (True to Life!) mineshaft into a game as a developer. Or as a gamer, trying to get sections imported into Minecraft as part of a custom adventure or story map. Maybe one day someone in a chair like me can do a full VR trip in the mines. And I'm sure there's a world of more possibilities from work like this. I am amazed and applaud the work done here
Brent! This is so great! I have disability that would LE compromise the chances for me to going the mine which has been on my bucket list. Can’t wait to download your future Cerro Gordo App. Delighted to see your new progress. Your glowing smile & big welcome gives me such joy. Thank you.
Brent this is a great way to move forward. Four years has past so fast and you have done so much mate and have enjoyed every step of the way. Kudos to you all the way from New Zealand..
That handheld scanner is impressively quick but you can tell how low poly the result is. I suppose it's good enough for what you want to do, cheers to both groups for helping out
Check out their link to their data on Reality Cloud Studio. It's not all their, but from what they have when you get in close it's still plenty detailed actually.
I am so happy to see 3D mapping being done of the site, as it is one of the best ways to preserve something so everyone presently and into future will be able to see a site like Cerro Gordo. I’d say it comes down to the detail of data set scans when you are talking preservation. As the first team seems to have, based on the video, a higher amount of total points giving you a fairly exact texture scan, which would be good if you want to have a high quality replica or use it in a movie cut cut scene, or looking into the future a physical simulation, where the second team it seems you have less points so it smooths over the granular detail, which is good for getting the good overall size and scale of a place, which is good for a first time understanding of a site or a site location that is very time sensitive for it remaining as you can map a location very quickly, intern it would a be good enough quality scan for directly importing into any game in the last 10 years, or a location map for tracking where you are in the mine.
Thank you for the content Brent! I wish so much I had something to offer to be able to be there once in my life. Unfortunately Im just a simple fan and will have to enjoy the town from your videos, been a fan since day 1 and I'm proud to be here. Please keep the updates coming brother!
Brent, just now finished reading your book. Thank you! My eyes teared up as I read the last page of the chapter Air. A fun story told well. A fellow desert rat looks forward to shaking your hand one day. Wishing you all the best!
It's amazing combinning hitech digital equipment with the old mine networks to preserve the history and potential uses for gaming, virtual reality viewing, and way more. So... You have a sound studio.... Filming opportunities and an amazing place. The possibilities are as endless as the mine shafts and tunnels. Great job Brent👍👌🤗
I wish my hometown had taken similar scans of our mine and archived them for posterity before the shaft was closed forever. In our mine, coal was mined from a depth of 1.5 kilometers for ~150 years (since 1849). My grandfather was a foreman in the mining industry, and my father also worked there. Even school friends of mine did their vocational training there. On the one hand, it is nice to see such projects and data, but on the other hand, it is sad when you think back to your own mines. Thanks for sharing, best regards from Germany.
Brent! Glad to see a video drop on a Saturday. I was in the middle of watching a movie and saw my notification pop up. Well, for me, when a Cerro Gordo video drops, I have to stop whatever I am doing to hit Play! But whoa! 3D mapping CG? As a claustrophobic person, I knew I would never be able to explore the mines in person, but this seems to open up the possibilities! One of my favorite scenes is from the movie Prometheus, the 5th installment of the Alien film series. In the movie, there is a scene, where the scientist uses drone scanners to map the alien ship. It is movie magic of course, but while watching the film, I was reminded that innovation comes from fiction. I cannot wait to see what the results of your data will create. ❤
That might have been movie magic then, but a recent study made by LKAB and Luleå University of Technology have shown that we've surpassed that kind of technology by now. They got drones not just mapping mines but doing other kind of tasks as well. Autonomously.
Imagine being in the mine with a mask on, then thinking about the Prometheus film and Aliens in general. Nothing like having Alien on your mind with something strapped to your face...
So much great information presented and so great to see all the advanced technology. This old mine is getting a lot of new technologies thrown at it. We can't wait to see how these results are displayed and presented. Totally amazing! Thank you for sharing all this exciting technology with us!
awesome. work Brent and all involved! Man, leica rules..What an beautiful implementation of technologies to built something like that equipment. Maybe I'll give a go and build a VR walkthrough of one of the parts of the mine with the data. Should b do'able.
Great job Brent. Exciting news for you and for those of us that have been following this story. I'm a 2020, 35K viewer fan. I can say I knew you when you first go there!
This is so great Brent - very excited to see and explore the final scanned images! It will be great to explore with the map on a portable device in the mine once completed. Congratulations!!
Wow!..this is so amazing taking history to a whole new level of discovering the past 🌬super exciting!…I’ve been following this channel since the beginning so amazing thank you for sharing🙏
I took three pictures once, moving from left to right and got an early pano of a ridge with fog after a storm. I was pretty happy with the way it turned out. Early panorama. About forty yrs. ago. So, I kind of dig this. Best of kindness to the folks who previously attempted this. A salute to Bruno. A guy who had the knowledge to tackle it. Take care and be safe and all that, and don't let every idiot enter the mine. Make everyone sign a release, for what that helps. Your going to take on tigers if anyone gets hurt that shouldn't have been there. Too much advice. So, in closing: a very impressive piece of work. The mine is lucky to have stumbled across Brett.
Great video. I’m pleased that those people shouted out to you and with the technology available today, helped you realise your dream of 3D mapping the tunnel systems. Thank you. Take care, keep safe. ❤ Dorset, UK
Lidar mapping will also show you what the vein looks like. A geologist can look at the pattern of the tunels, and it could help them to figure out where to dig to find the vein again.
Just got to this, you are one of my few channels I stop everything to just relax on. I appreciate your approach on life. And only wish I get the opportunity to see, touch and remember as much history as you haha!
Brent, have you ever looked into the person/people who did the USGS who did the survey? It would be cool to talk about them on the channel. I've imagined a couple times when you reference it how one or a few government employees ventured into long abandoned mines in a remote area and did such a professional job. Pretty cool to think about.
Cerro Gordo looks more and more like an amazing community platform / entertainment park for positive and creative adults wanting to experiment and leverage their craft/passion/expertise to support together (but each in their own ways) a shared multidimensional celebration of the epic past of the US gold rush times (ok silver)... all thanks to the contagious and authentic enthusiasm of one single person...Brent! Really amazed to follow your amazing adventures, from the start, thousands of kilometers away in Paris, France ;)
Hey Brent, amazing technology, way ahead of this old-timer, heard Jeff Williams a geologist/U-tuber/miner talk about it awhile back, all above my flintstone mind, Lol! Glad to see you've been able to apply it to Cerro Gordo, I'm sure something outstanding will become of it... keep it up and keep it happening! ⛏️⚒️👍🤯🤠

I started following Brent just after the Hotel fire, maybe 3-4 months after and being able to see a 3D rendering of the mine is mind blowing on so many levels!
A lot future generations owe you a gigantic thank you.
wow thanks
As a lidar specialist myself, I love getting to see fellow LiDARians at work picking up some really cool point clouds!
This may be too personal, but how well does that field pay?
@@Sir-DavidJamesAnd how does one get into the scanning? All offers I see are "boring" remote sensing hehe
@@rafall1118 this literally is remote sensing. how "boring" it is depends on the projects you get to work on, and what field you're in. I've been doing lidar for almost 20 years, and now i'm starting to look into the drone 3D mapping (more of a phodar) for small projects. There are dozens of directions you can take it!
That handheld rig might come in handy to see what's behind any collapsed sections you can't physically fit into.
Strap one on a remote control car
Wouldn't a cheap camera be smarter in case it's not recoverable?
send the drone
@@ionymous6733 I didn’t get to plan B
@@ionymous6733 Both a camera and this rig are handheld. And a camera doesn't give you all the data that lidar does.
I could see how the drone going down the jefferson Chimney could help unlock where it connects in to the rest of the system. I know you already were able to do to some of the connection. But to be able to send down the drone without risking lives is a game changer. If only they had a drone with tank treads that could be sent through small gaps or collapts.
theren was a company couple years ago trying to lunch a drone with tracks, dont know if they succeded
They would have to make it as a drone in 2 units for safety foward lidar drone and have it tethered to a back up tow drone in case the first drone accidently drove off a ledge into a chute or got stuck.
most drones rely on connections like GPS, bluetooth, wifi, etc. these won't work through dense rock, so unless it's a straight shot it would be problematic. one on tracks would be neat. just a gopro attached to a vehicle of some sort... though you still need that connection to work to the controller.
@@jlt131 a thethered one would solve the problems a drone on tracks could have in the mine. ease of ercovery and no jamed signals.
@@patdbus true! great idea
As an underground geologist myself who uses Lidar stuff all the time this is outstanding!! looking forward to more follow ups of this!
We thank you, Brent, for bringing the wonder and joy of Cerro Gordo to millions of people. Long may it continue!
As a fan of Corridor Crew, it’s great to hear they’ve helped you.
Huge thanks to Bishops' University and Leica for taking so much time to map such a wonderful piece of history - preserving it for the rest of us.
This video truly does illustrate the places where the technology shines - and where the technology needs to be improved.
What an excellent learning experience for the students (my assumption). Although my field was different, going on trips with teachers and professors to things relating to my major were always memories that stuck around.
Again - great job and thanks to all involved!
Another Home Run show, I know that all of us ,now speaking for everyone who follows you, Great job again, just keep them coming and we will keep watching and living thru these shows
As a IT nerd and co-owner of The Mahoney Mine, it would be pretty easy - and informative - to be able to compile and release a 3d walk through on Quest or Playstation 3D. Not to mention lucrative. Reach out to us!
Winter is coming.. Gotta get those projects completed 😎
They're getting done. Big update on all progress above ground next weekend!
You are a great Story Teller and the enthusiasm is contagious.
I remember commenting about this idea under one of your videos about 2-3 years ago , cool that you are doing it and it actually looks dope!
Sure you did. And I invented the internet. Damn that theiving al gore!
@@JamesBuddell-fn6bz Sad that negativity was brought to this, but if anyone wants proof here is a screenshot (on the comment it says 2 years ago in Latvian) i.pinimg.com/originals/59/db/4b/59db4bb0d14b28db1a651c9b8bc81e9e.jpg
@@JamesBuddell-fn6bz OP wasn't taking credit for giving the channel the idea, just expressing gratification that a thing he suggested has become a reality. I'm sure all the owners of VR headsets subscribed to this channel have had the same thought independently, and I'm sure many of them have made the suggestion in the comments. I myself left a comment on one of his videos some years ago that he should try to get in touch with someone from Epic Games to come out and do photogrammetry and LIDAR scans to recreate Cerro Gordo in Unreal Engine for a VR experience. I would imagine the channel probably gets a couple dozen such comments on every video it uploads.
The fact that you are sharing all the data is awesome...in no time someone will have 3D printed the entire thing in sections that you can open and explore from the comfort of your museum room.
Thank you to all who were involved.
What a great team and dept!! Its amazing what this technology can give you and us as a viewer. So awesome to have such a willing group come out and spend time working on it!!
That Leica mapping tech is incredible! I hope the university is able to get that new Leica equipment. They've definitely earned it!
Slightly different tools, the LiDAR will give sub-mm precise measurements of the whole space, the Leica scanner will give you the general shape of the space quickly.
The Leica stuff will end up with huge errors underground. I've used it extensively within buildings, it's fast, but inaccurate.
At $55,000 for just the handheld unit, there aren't many universities that are going to be buying that system.
@@Ammoniummetavanadate Is that type of high resolution LiDAR over kill for this application? I think the trade-off between speed or accuracy favors the Leica system.
@@259Den3 Really depends on what you want to do with the data.
If you are detecting say movement in the rock in certain areas over time that might absolutely be needed.
Or if you want very accurate three dimensional positioning data.
Incredibly interesting. You are the man, you were chosen to be at Cerro Gordo you pull it together.Thank you.
Awesome episode Brent! We've watched you from the start and are amazed at what you're doing there in Cerro Gordo! 2:12
The beauty of the surrounding hillsides, all green after the major snows [and rains you had is truly awesome 🎉
I’m so glad you’re still sharing your dream with us. These videos are amazing. I do worry when you’re off hiking alone but you have such beautiful views of the valley and mountains
you need to rent that scanner for a month or 2. you could walk the entire mine and send them the data to break down. awesome vid bro
Brent: This is something new to me. Very excited to see the outcome of the 3D mapping. Bringing your history to life.
Thank you for another amazing video. Keep up the great work. Now I can't wait for your American Hotel to reopen. Regards 🇿🇦.
What a cool project, always a treat to get an update, but this one was wild! Those little scanners are nuts, the maps are such an invaluable advancement in safety and opens so many possibilities for future cave mapping!
This is so fascinating! The deeper level's size being totally wrong in estimation is definitely a testament to how big mines can get and like how a dark winding corridor can really mess with your senses, smaller areas just feel smaller overall when they are really much bigger! It would be cool to get some crawling drones in there to transmit to each other in a kind of mesh network to scan other parts of the mine which are not as safe for people to go to, or maybe like the radar that oil drillers use to look for oil.
High Brent from Eastern Tennessee have been watching your channel from the beginning. Your all heart i really enjoy watching very cool Take care.
Great video Brent and so glad that things are progressing and your smile tells it all. Thanks for the update Brent, greatly appreciated.
This is so freaking cool! Congratulations on another milestone!
Thank you so much!
I can easily imagine researchers a 100 years from now being so thankful this dataset exists. Taking new mapping and comparing to the old one, seeing how the mine evolved and moved over the centuries.
I remember when you first spoke of getting the mines mapped. Excited to see the end result. 👍
The contrast between fancy computers and Lidar and the 1800s mine is so satisfying
I LOVE this for you!!! I can forsee so many ways you'll be using all of this to really help Cerro Gordo in preservation AND rejuvenation.
Brent!!!!!!! Hello right back at you buddy..
I've been here since u started your journey from Texas.
I got to say I'm proud of you. I hope the fur babies are good I never see him anymore. Stay safe, stay intrigued, stay spooky..💜
Nice to see someone preserving history instead of destroying it😊
LOL what are you talking about? the mines look full of trash now
You saying that you may be able to make a new portal into the mine with this data at the 5:20 mark makes me happy for you and also take me back to a few videos ago where I asked if such a thing would ever be possible. :)
When I was a kid we went down into a shaft mine and I got turned around (AKA Lost). Totally terrified. lol Seeing you guys down there makes my hands sweat, but it is so entirely cool I can't help but watch.
When in high school 2 of us went into the asbestos mines in Benicia and while wandering round with our flashlights, we found a vertical shaft. Soon voices from down the shaft implored us to shine light down the shaft till these 3 college students found a way up 3 layers. They were grateful
@@williamoorejr I think I was about 12 or 13. Even as an adult I still can't imagine the terror I'd feel of being lost in there. lol
Maybe im just nuts but you wouldnt catch me in one of these places without a ton of prep
You can see the significantly lower quality of the Leica handheld. It's obviously much faster though, so if the accuracy is enough it might be just right for your purposes. That said, from a historical-preservation perspective, the high resolution is fascinating as it shows so much more detail in the mining techniques etc. and is more usable for a full VR application or similar.
They should take a combined approach. Brent needs the fast data to try and get around the collapses, while we need the high-accuracy scan for preservation purposes.
Awesome . Can't wait to watch. Keep doing a good job Bruvver. I'm in SE B.C. and been a prospector for 24 yrs. I've watched you from day 1 I'll get a passport and come see Cerro Gordo 1 day soon I hope. I can drive truck and run equipment especially 🔨 and Shovel 🍻
Awesome! See you up here sometime
You are nothing but amazing Brent. Cheers from me my husband and many friends of ours who follow you. Cheers

This is really exciting to see! Congratulations for making it happen, and as always, your work and vibe are much appreciated by those of us living vicariously😊
What an awesome way to bring history alive for us and the next generation. This will be neat to add to your museum once it’s all scanned. 👍❤️
Yes at this rate the museum and hotel will open in 2087
@@attorneyscottmiller1429damn, that's 10 years after the nuclear apocalypse.
So many cool experiences have come out of this old mine. Thanks for bringing us all along for the ride, Brent!
I really enjoy watching and listening about the history of Cerro Gordo
and now seeing the 3D map of the Union Mine is really great thanks
and have a great weekend Thank You.🤠👍🇺🇲
Having that cell tower right there, guaranteeing access to communication, is a huge safety feature too. If you could lay a hard line (or a series of routers) from deep inside the mine to a router with access to the tower that would be huge too.
❤❤Purely amazing being able to map the mine technology has come along way since the mine first started WELL DONE 👍👍👍👍👍👍👍
I'm thrilled to see a move in a similar vein (always intend your puns, everybody) from the work done when the (iirc) CC folks went up to Cerro Gordo.
These maps alone would be an amazing thrill to explore around.
The wide ranging possibilities for work like this asked me.
Someone working as an historian, creating a history book of this mine system, with links in a digital edition that take the reader to the exact locations relevant to the account.
Or using scans like this to put a realistic (True to Life!) mineshaft into a game as a developer.
Or as a gamer, trying to get sections imported into Minecraft as part of a custom adventure or story map.
Maybe one day someone in a chair like me can do a full VR trip in the mines.
And I'm sure there's a world of more possibilities from work like this.
I am amazed and applaud the work done here
What a great project! The possibilities with these technologies is very exciting!
Brent! This is so great! I have disability that would LE compromise the chances for me to going the mine which has been on my bucket list. Can’t wait to download your future Cerro Gordo App. Delighted to see your new progress. Your glowing smile & big welcome gives me such joy. Thank you.
Amazing, Brent.
You inspire so many people!!!
Brent this is a great way to move forward. Four years has past so fast and you have done so much mate and have enjoyed every step of the way. Kudos to you all the way from New Zealand..
THANK YOU SO VERY MUCH SIR. PLEASE TAKE CARE OF YOURSELF AND ALL YOUR FRIENDS AND TEAM MEMBERS PLEASE BE CAREFUL.
That handheld scanner is impressively quick but you can tell how low poly the result is. I suppose it's good enough for what you want to do, cheers to both groups for helping out
Check out their link to their data on Reality Cloud Studio. It's not all their, but from what they have when you get in close it's still plenty detailed actually.
I am so happy to see 3D mapping being done of the site, as it is one of the best ways to preserve something so everyone presently and into future will be able to see a site like Cerro Gordo. I’d say it comes down to the detail of data set scans when you are talking preservation. As the first team seems to have, based on the video, a higher amount of total points giving you a fairly exact texture scan, which would be good if you want to have a high quality replica or use it in a movie cut cut scene, or looking into the future a physical simulation, where the second team it seems you have less points so it smooths over the granular detail, which is good for getting the good overall size and scale of a place, which is good for a first time understanding of a site or a site location that is very time sensitive for it remaining as you can map a location very quickly, intern it would a be good enough quality scan for directly importing into any game in the last 10 years, or a location map for tracking where you are in the mine.
Brett you are living the dream my friend thank you for the 4 years of Adventure you took us all on
Leica makes quality built optics and equipment. Very impressed with the 3 D mapping. Big thanks for sharing 😊👍
Understatement of the last 2 centuries, LOL....Leica ROCKS
WOW! Amaizing idea executed by an elite crew. I never knew LiDAR could be applied to underground mapping like that. Totally blown away!
Yaaay good to see more of cerro gordo history ❤
Thanks for being here!
Thank you for the content Brent! I wish so much I had something to offer to be able to be there once in my life. Unfortunately Im just a simple fan and will have to enjoy the town from your videos, been a fan since day 1 and I'm proud to be here. Please keep the updates coming brother!
really cool to hear the explanation of how lidar works, great video
As someone whose mom works at Bishops, this was such a fun crossover for me! Great video, really enjoyed seeing the map made.
as having used photoscape to document argaeologial excavations, this is the point i have been waiting for!
Brent, just now finished reading your book. Thank you! My eyes teared up as I read the last page of the chapter Air. A fun story told well. A fellow desert rat looks forward to shaking your hand one day. Wishing you all the best!
Yay another videos of cerro gordo. Great to see Brent
Been waiting for this video on 3D mine scans for a long time! So excited to see it coming together! You really are making history. :)
Ive always wanted a piece of smithsonite from the mine and now I get to view them in the near future!
It's amazing combinning hitech digital equipment with the old mine networks to preserve the history and potential uses for gaming, virtual reality viewing, and way more. So... You have a sound studio.... Filming opportunities and an amazing place. The possibilities are as endless as the mine shafts and tunnels. Great job Brent👍👌🤗
To have Leica come out is WILD. Awesome stuff as always!
Awesome idea. Finally see the inner workings of this mine. Thankyou Brent for making this possible.
First time checking in a while to see some really cool content
Thanks!
Brent, your perseverance is paying off in many ways.🙏
Great job seeing all of the tunnels
I wish my hometown had taken similar scans of our mine and archived them for posterity before the shaft was closed forever. In our mine, coal was mined from a depth of 1.5 kilometers for ~150 years (since 1849). My grandfather was a foreman in the mining industry, and my father also worked there. Even school friends of mine did their vocational training there. On the one hand, it is nice to see such projects and data, but on the other hand, it is sad when you think back to your own mines. Thanks for sharing, best regards from Germany.
Brent! Glad to see a video drop on a Saturday. I was in the middle of watching a movie and saw my notification pop up. Well, for me, when a Cerro Gordo video drops, I have to stop whatever I am doing to hit Play! But whoa! 3D mapping CG? As a claustrophobic person, I knew I would never be able to explore the mines in person, but this seems to open up the possibilities! One of my favorite scenes is from the movie Prometheus, the 5th installment of the Alien film series. In the movie, there is a scene, where the scientist uses drone scanners to map the alien ship. It is movie magic of course, but while watching the film, I was reminded that innovation comes from fiction. I cannot wait to see what the results of your data will create. ❤
That might have been movie magic then, but a recent study made by LKAB and Luleå University of Technology have shown that we've surpassed that kind of technology by now. They got drones not just mapping mines but doing other kind of tasks as well. Autonomously.
Imagine being in the mine with a mask on, then thinking about the Prometheus film and Aliens in general. Nothing like having Alien on your mind with something strapped to your face...
So much great information presented and so great to see all the advanced technology. This old mine is getting a lot of new technologies thrown at it. We can't wait to see how these results are displayed and presented. Totally amazing! Thank you for sharing all this exciting technology with us!
awesome. work Brent and all involved! Man, leica rules..What an beautiful implementation of technologies to built something like that equipment. Maybe I'll give a go and build a VR walkthrough of one of the parts of the mine with the data. Should b do'able.
Great job Brent. Exciting news for you and for those of us that have been following this story. I'm a 2020, 35K viewer fan. I can say I knew you when you first go there!
Super interesting for us guys on the sofa at home !!!
This is so great Brent - very excited to see and explore the final scanned images! It will be great to explore with the map on a portable device in the mine once completed. Congratulations!!
You should have one of the crews use that LiDAR-Radar drone to map all the vertical of the Jefferson Chimney
Wow!..this is so amazing taking history to a whole new level of discovering the past 🌬super exciting!…I’ve been following this channel since the beginning so amazing thank you for sharing🙏
Really cool to see the two difrent ways to do it. And good fun to see another video.
Glad you enjoyed it!
I took three pictures once, moving from left to right and got an early pano of a ridge with fog after a storm. I was pretty happy with the way it turned out. Early panorama. About forty yrs. ago. So, I kind of dig this. Best of kindness to the folks who previously attempted this. A salute to Bruno. A guy who had the knowledge to tackle it. Take care and be safe and all that, and don't let every idiot enter the mine. Make everyone sign a release, for what that helps. Your going to take on tigers if anyone gets hurt that shouldn't have been there. Too much advice. So, in closing: a very impressive piece of work. The mine is lucky to have stumbled across Brett.
Great video. I’m pleased that those people shouted out to you and with the technology available today, helped you realise your dream of 3D mapping the tunnel systems. Thank you. Take care, keep safe. ❤ Dorset, UK
The laica handhelds are incredibly impressive, fitting enough processing power into it that the scanning and stitching can all be done onboard
Respect to the Leica people for respecting their heads with helmets.
Just amazing what you are doing for this town, Brent. Thank you.
Lidar mapping will also show you what the vein looks like. A geologist can look at the pattern of the tunels, and it could help them to figure out where to dig to find the vein again.
Just got to this, you are one of my few channels I stop everything to just relax on. I appreciate your approach on life. And only wish I get the opportunity to see, touch and remember as much history as you haha!
Brent, have you ever looked into the person/people who did the USGS who did the survey? It would be cool to talk about them on the channel.
I've imagined a couple times when you reference it how one or a few government employees ventured into long abandoned mines in a remote area and did such a professional job. Pretty cool to think about.
Cerro Gordo looks more and more like an amazing community platform / entertainment park for positive and creative adults wanting to experiment and leverage their craft/passion/expertise to support together (but each in their own ways) a shared multidimensional celebration of the epic past of the US gold rush times (ok silver)... all thanks to the contagious and authentic enthusiasm of one single person...Brent! Really amazed to follow your amazing adventures, from the start, thousands of kilometers away in Paris, France ;)
"This is the shaft here. That's what we'll be going down on" giggity 🤭🤭
Hey Brent, amazing technology, way ahead of this old-timer, heard Jeff Williams a geologist/U-tuber/miner talk about it awhile back, all above my flintstone mind, Lol! Glad to see you've been able to apply it to Cerro Gordo, I'm sure something outstanding will become of it... keep it up and keep it happening! ⛏️⚒️👍🤯🤠
