Working Down the Mines
Pics I have scanned from my photos which have turned out quite well I thought. From when I worked underground 1968 - 1981. The first part is Windarra nickel mine, 212 miles north of Kalgoorlie Western Australia. This was a trackless decline with some pretty big gear, 35 ton Wigmore Caterpillar trucks which were a modified 631 scraper with a tipping body, and 3-boom Gardner Denver pneumatic jumbos. They had open stopes with longholes drilled with GD Airtracs and some bar-and-arm machines. From memory I think one of the big stope blasts was 100,000 tons. The mine closed in the early '80s and was gutted. There were a few deaths down there, all rockfalls, all on my shift, so R.I.P. to those guys. The second part is Lake View & Star gold mine, on Kalgoorlie-Boulder's Golden Mile. I worked there as a machine miner on airlegs doing shrink stoping and intermediate driving (drifting). We worked by ourselves with no partner which was the practise then. We used Holman's Silver 3s and Silver 900 airleg machines (jacklegs). Mucking out inter drives we used air or electric 2-drum scrapers into a raise. We used AN60 dynamite primers with ANFO and electric detonators or sometimes safety fuse. This was a "traditional" mine with rail drives leading to a vertical shaft about 3000' deep from memory. The mines on the Golden Mile no longer exist because they have been swallowed up by the Super Pit.

Erickson Gold Mining Claim - Colorado - 2017
The Erickson mine was discovered in 1880 when the price of silver was still supported by the US government. The mine was abandoned in the 1890s when the price of silver drastically fell. The mine reopened several times since then, with the intent to mine for gold. Today the mines will need extensive rehabilitation. The entrances will need to be dug out and supported and there are several collapsed structures on the claim. Surveyors report large amounts of visible gold found in the discarded ores. It would be smart to start working the existing ore dumps before working the veins underground.

CBS created The Search, an educational series produced by the Public Affairs Department, in the 1950s to share scientific research with viewers in an easy-to-understand manner. The 26-episode series aired over 1954 and 1955. This episode, “Colorado School of Mines: Uranium Prospecting and Mining, Golden Colorado,” is hosted by Charles Romine and shows all the phases of the uranium rush happening on the Colorado Plateau. The film begins with footage of atomic bombs detonating (00:50; 01:08) as Romine narrates the incredible power of atomic energy that can be used for destruction or for helping human life. The key to atomic power is uranium, and Romine (01:47) takes viewers on a tour of mining uranium on the Colorado Plateau. Romine visits with Professor Paul Keating, a pioneer in uranium fields, who explains the geology of uranium and some of its early uses by the Ute and Navajo Indians. Next, Romine meets with prospectors to learn about the early stages of mining. He speaks with a prospector who owns a mine on Davis Mesa (04:28); the prospector explains how to stake a claim (05:19). Romine then goes to the Montrose County courthouse (05:48) where he learns how to file a claim for mining. Afterward, Romine visits with a successful miner in Grand Junction (07:49) and learns how to start a mine, including financing one. One way to finance is through selling stock; the film shows the Salt Lake Stock Exchange (11:26) where people are speculating on stocks. Romine travels to the Colorado School of Mines (12:19) to learn about the university’s Prospector Service, observing the samples sent in to the lab (12:46). The lab identifies what the minerals or metals are in the samples, but also allays the samples, determining the amount of mineral or metal, using instruments such as the Geiger counter (13:33). A lab technician explains how a Geiger counter works (14:54). Next, Romine observes an exploration operation, watching mining equipment in action (16:48) and going on an aerial survey (18:44) to locate likely uranium deposits. Once a site is located, the operation builds roads (19:42) into the sides of the mesas and create a functional camp on top (20:06) with their own testing laboratory (20:32). Once the exploration operation determines that the mine has commercial-grade uranium, large-scale mining operations commence, such as the U.S. Uranium Corporation in Paradox Valley (21:10). The episode concludes with Romine and Keating discussing mining uranium and the future of uranium.

Underground in a small mine near Beaverdell
Initial prospecting began in the Beaverdell area in the late 1880s. The first ore was shipped in 1896. The major producing mines in the Beaverdell silver-lead-zinc vein camp, from west to east, were the Wellington (082ESW072), Sally and Rob Roy (082ESW073), Beaver (082ESW040), and Beaverdell (082ESW030), with numerous other small workings throughout the area. Production commenced on the Highland Lass in 1922. In 1930, R.B. Staples and associates obtained control of the Bell and Highland Lass, however production was recorded separately until the purchase was complete in 1936. Production continued under the amalgamated Highland-Bell mine owned by Highland-Bell Ltd. Highland-Bell Ltd. was purchased by Leitch Gold Mines Ltd. in 1946 but operations continued as the Highland-Bell mine. In 1953, a down-faulted section of the Lass vein system was found 229 metres vertically lower and developed by a 1600-metre adit. Teck Corp. assumed control of the mine in 1970. In 1986 and 1987, property exploration by Teck Corp. located an eastward ore extension with increased gold content on the lower (2900) level. This included an ore block containing 5442 tonnes grading 1371 grams per tonne silver (Assessment Report 15790). Production ceased in 1991

Fantastically Preserved Old Mine Out In The Desert
It is a rare treat to come across an abandoned mine that is preserved as well as this one. Taking the age of this mine into account, having the mining equipment still in working order, having all of those tools still around, still being able to read the paperwork left inside the mine – that’s pretty extraordinary stuff when compared to most abandoned mines (and we’ve been to quite a lot of them now). We primarily have the dry desert conditions to thank for the mine being in this state as well as the fact that it is exceedingly difficult to get to it (However, I also think that not many people know about this particular abandoned mine). There are no roads to this mine – only the remains of a mule trail, which is now very faint. So, think about the fact that EVERYTHING you see at this site was hauled in on foot by men or mules. That’s impressive considering the amount of rail and some of the heavy equipment at this mining operation. I love sites like this because they give such a great insight into how the miners lived in the past. Based on the artifacts at this site, for example, we know what the miners read, what they ate, where they washed their hands, where they slept at night, etc. It is not difficult at all to imagine what day-to-day life was like for the crew of miners that worked here. A few questions I had… I would be very curious to know what the other building next to the intact miner’s cabin that we explored was (the building that had tumbled down the wash). We found artifacts quite a way down that wash, but nothing that gave us an insight into what that particular building was. Given the other bedframe present at the site, it might have just been another place to sleep. Hard to imagine miners sharing a bed and there was just one bed in the cabin we explored! Also, I would be curious to know where the stamp mill was and how large it was. It seems that a fair amount of it may have been buried from the waste rock pile shifting. Lastly, I would love to know more about that caved adit across from the miner’s cabin. Was that the original adit at this site? How far back did it go? As I said at the introduction to this video, credit for locating this mine goes to my exploring buddy, Adit Addicts, whose YouTube channel can be found here: https://www.youtube.com/channel/UCIXOU8aR7o50X6q2wQ0wbCQ All of these videos are uploaded in HD, so adjust those settings to ramp up the quality! It really does make a difference… You can click here for the full playlist of abandoned mines: https://goo.gl/TEKq9L Thanks for watching! ***** Growing up in California’s “Gold Rush Country” made it easy to take all of the history around us for granted. However, abandoned mine sites have a lot working against them – nature, vandals, scrappers and various government agencies… The old prospectors and miners that used to roam our lonely mountains and toil away deep underground are disappearing quickly as well. These losses finally caught our attention and we felt compelled to make an effort to document as many of the ghost towns and abandoned mines that we could before that niche of our history is gone forever. But, you know what? We enjoy doing it! This is exploring history firsthand – bushwhacking down steep canyons and over rough mountains, figuring out the techniques the miners used and the equipment they worked with, seeing the innovations they came up with, discovering lost mines that no one has been in for a century, wandering through ghost towns where the only sound is the wind... These journeys allow a feeling of connection to a time when the world was a very different place. And I’d love to think that in some small way we are paying tribute to those hardy miners that worked these mines before we were even born. So, yes, in short, we are adit addicts… I hope you’ll join us on these adventures! #ExploringAbandonedMines #MineExploring #AbandonedMines #UndergroundMineExploring

King's Canyon Gold Mine - Colorado - Gold Rush Expeditions - 2015
Website: https://www.goldrushexpeditions.com/ Mining Claims for Sale: https://www.goldrushexpeditions.com/store/mining-claims-for-sale/ Facebook: https://www.facebook.com/GoldRushExpedinc National Bureau of Mines: http://www.nationalbureauofmines.org/ Today on Gold Rush Media Corey and Jessica walk us through the Historic King's Canyon Gold Mine. This combination Lode and Placer claim is resides in Jackson County, Colorado. The King's Canyon claims are a great example of elusive, but massive gold mines, which Colorado is known for. A well maintained road passes within a mile of the claims, but the mines lie hidden up an old overgrown road. There are two claims, a lode and placer, that cover two separate mining operations. Estimated years of operation were from the 18960s-1940s. The area is a mining wonderland.
Gold Rush Expeditions, Inc.® presents The American Flag Mine©, Colorado
The American Flag mine© is a lode (underground) mine worked for gold and opal values from 1885 to 1967. The property contains the entirety of the American Flag Mine©, which consists of a shaft, and inclined adit and a series of small prospects. The shaft has been gated and covered by the Colorado Division of Mines in 2003 and will require a permit to reopen. The decline has also been gated but not backfilled and could be easily accessed with a permit. The property also contains the Ace High-Jackpot Mine which was originally located for Gold and copper in chalcopyrite ore. The Ace High consists of a collapsed decline adit and a possible shaft. The workings will need rehabilitation to be further investigated. The American Flag Mine© is noted for native gold production in some copper bearing minerals including chrysocolla and malachite. It is reported to contain at least 3500’ of workings. These working are said to interconnect (between the shaft and the decline). This has not been verified by surveyors due to gating on the mines. Surveyors took samples from the waste dumps at the American Flag Mine©. These assays returned .17 oz/T in Gold. There are no defined reserves.

Support Our Channel : https://www.patreon.com/PeriscopeFilm This film THE ATOM UNDERGROUND profiles Project Gasbuggy and Project Plowshare, which were ill-fated attempts to demonstrate the use of nuclear detonations for peaceful purposes, in this case extracting more oil and natural gas from underground through nuclear fracking. Plowshare was the overall United States term for the development of techniques to use nuclear explosives for peaceful construction purposes. It was the US portion of what are called Peaceful Nuclear Explosions (PNE). Successful demonstrations of non-combat uses for nuclear explosives include rock blasting, stimulation of tight gas, chemical element manufacture (test shot Anacostia resulted in Curium-250m being discovered), unlocking some of the mysteries of the so-called "r-Process" of stellar nucleosynthesis and probing the composition of the Earth's deep crust, creating reflection seismology Vibroseis data which has helped geologists and follow on mining company prospecting. Negative impacts from Project Plowshare’s 27 nuclear projects generated significant public opposition, which eventually led to the program's termination in 1977. These consequences included Tritiated water (projected to increase by CER Geonuclear Corporation to a level of 2% of the then-maximum level for drinking water) and the deposition of fallout from radioactive material being injected into the atmosphere before underground testing was mandated by treaty. Project Gasbuggy was an underground nuclear detonation carried out by the United States Atomic Energy Commission on December 10, 1967 in rural northern New Mexico. It was part of Operation Plowshare, a program designed to find peaceful uses for nuclear explosions. Gasbuggy was carried out by the Lawrence Radiation Laboratory and the El Paso Natural Gas Company, with funding from the Atomic Energy Commission. Its purpose was to determine if nuclear explosions could be useful in fracturing rock formations for natural gas extraction. The site, lying in the Carson National Forest, is approximately 34 km (21 mi) southwest of Dulce, New Mexico and 87 km (54 mi) east of Farmington, and was chosen because natural gas deposits were known to be held in sandstone beneath Leandro Canyon.[3] A 29 kt (120 TJ) device was placed at a depth of 1,288 m (4,227 ft) underground, then the well was backfilled before the device was detonated; a crowd had gathered to watch the detonation from atop a nearby butte. The detonation took place after a couple of delays, the last one caused by a breakdown of the explosive refrigeration system. The detonation produced a rubble chimney that was 24 m (80 ft) wide and 102 m (335 ft) high above the blast center. After an initial surface cleanup effort the site sat idle for over a decade. A later surface cleanup effort primarily tackled leftover toxic materials. In 1978, a marker monument was installed at the Surface Ground Zero (SGZ) point that provided basic explanation of the historic test. Below the main plaque lies another which indicates that no drilling or digging is allowed without government permission. The site is publicly accessible via the Carson National Forest, F.S. 357 dirt road/Indian J10 that leads into the Carson National Forest. Following the Project Gasbuggy test, two subsequent nuclear explosion fracturing experiments were conducted in western Colorado in an effort to refine the technique. They were Project Rulison in 1969 and Project Rio Blanco in 1973. In both cases the gas radioactivity was still seen as too high and in the last case the triple-blast rubble chimney structures disappointed the design engineers. Soon after that test the ~ 15-year Project Plowshare program funding dried up. These early fracturing tests were later superseded by hydraulic fracturing (fracking) technologies.

50 Mining Engineering Interview Questions And Answers || Frequently asked questions in an interview
Mining engineering is an engineering discipline that applies science and technology to the extraction of minerals from the earth. Mining engineering is associated with many other disciplines, such as geology, mineral processing and metallurgy, geotechnical engineering and surveying. A mining engineer may manage any phase of mining operations – from exploration and discovery of the mineral resource, through feasibility study, mine design, development of plans, production and operations to mine closure. With the process of Mineral extraction, some amount of waste and uneconomic material are generated which are the primary source of pollution in the vicinity of mines. Mining activities by their nature cause a disturbance of the natural environment in and around which the minerals are located. Mining engineers must therefore be concerned not only with the production and processing of mineral commodities, but also with the mitigation of damage to the environment both during and after mining as a result of the change in the mining area. Salary and statistics Mining salaries are usually determined by the level of skill required, where the position is, and what kind of organization the engineer is working for.[citation needed] When comparing salaries from one region to another, cost of living and other factors need to be taken into consideration. Mining engineers in India earn relatively high salaries in comparison to many other professions, with an average salary of $15,250. However, in comparison to mining engineer salaries in other regions, such as Canada, the United States, Australia and the United Kingdom, Indian salaries are low. In the United States, there are an estimated 6,630 employed mining engineers, with a mean yearly salary of USD$90,070. Education Students outside Colorado School of Mines campus There are many ways to become a Mining Engineer but all include a university degree in Mining Engineering. Primarily, training includes a Bachelor of Engineering (B.Eng. or B.E.), Bachelor of Science (B.Sc. or B.S.), Bachelor of Technology (B.Tech.) orBachelor of Applied Science (B.A.Sc.) in Mining Engineering. Depending on the country and jurisdiction, to be licensed as a mining engineer a Master's degree; Master of Engineering (M.Eng.),Master of Science (M.Sc or M.S.) or Master of Applied Science(M.A.Sc.) maybe required. There are also mining engineers who have come from other disciplines e.g. from engineering fields likeMechanical Engineering, Civil Engineering, Electrical Engineering,Geomatics Engineering, Environmental Engineering or from science fields like Geology, Geophysics, Physics, Geomatics, Earth Science,Mathematics, However, this path requires taking a graduate degree such as M.Eng, M.S., M.Sc. or M.A.Sc. in Mining Engineering after graduating from a different quantitative undergraduate program in order to be qualified as a mining engineer.

Gold Rush Media
There are nearly 500,000 abandoned mines across the United States. Those mines built this country. Towns, Rail and Industry exploded across the states. In 1942 President Roosevelt terminated all Gold Mine Operations. "In the interest of national defense, the War Production Board, in 1942, issued it Limitation Order L-2081 ordering nonessential gold mines to close down." Thousands of miners left for the war, never to return to their underground treasures again. Mining appeared to be bombed out for good. However, Gold mining is not dead! We are in a 21st Century Gold Rush. Join us as we tour the Western United States, exploring and documenting our Nation's History
Exploring the Abandoned Keystone Mine (Part 1 of 6)
We're back! I took a break due to my unusually busy schedule over the past two months. I will be attempting to upload on a weekly or bi-weekly basis again going forward. The Keystone Mine is a gigantic complex of tunnels on numerous levels containing over 25 miles of workings. The mine was exploited for tungsten and was a major producer of tungsten in the US. The Keystone deposit was discovered in the late 1800's and was mined almost continuously until the 1980's. The mine changed hands many times and was operated under several companies. The mine is connected via a triple compartment vertical shaft. The shaft collar is at around the 6500 level so it only intersects the 6400 level and below. Per documents found onsite, we determined the shaft descends to the 5600 level, 600ft below the level we explore in the video. The levels beneath the 6100 level, are flooded however. There are also numerous levels above the shaft collar. Some of those levels will be explored in later videos. This mine is seriously big and cannot be explored even in a weekend. We only explored about 1/6 of the mine in three days! #urbex #abandonedmine #mineexploring #abandoned #mining #exploring #desert #travel #history #adit #shaft #underground #minerals #silvermine #goldmine #exploringabandonedmines

State Police Interrupt a Gold Mining Operation in Oregon!
Our mining claim neighbors called the Cops! People living on the other side of the river where our mining claim is and not liking our mining, called the cops. It appears our neighbors just did not want their liberal utopia disturbed so they call the cops to harass us. The police were very cool as I knew one of them from checking our permits on another river couple months earlier and an Oregon DEQ meeting he showed up at. The rude lady yells to at from other side of river "you need a permit to do that"...we had them of course. She also told cops we were disrespecful and rude to her...which was totally false. She made up her own narrative about what was happening to justify her being annoyed. Liberal tactic # 3, change the narrative or just plain lie! This is the short version of the video, filmed on the Applegate River in Oregon while we were LEGALLY GOLD MINING! In the video, it is a continuous video, shot on my GoPro camera that I was wearing on my head. The video shows me mining and moving around with no editing to show what actually goes on while mining. Then my buddy is helping me move rocks while I'm using a sub-surface dredge...then the cops show up , and I tell him is where the action starts. UPDATE Jan 1st, 2015: In response to some of the comments saying we are uneducated, rednecks and other stuff...the guys in the video are as follows. One is a millionaire CPA, another a self employed business owner, two others are also self employed and owns a body shop and the other an internet marketer and freelance videographer, and lastly one is the son of the CPA guy and currently in college. Oregon Mining Law: Next time this happens, I will ask the State Police to cite the offending people who disrupt our mining operation based on this Oregon Mining Law: "ORS 517.133 Interfering with a mining operation. (1) As used in this section, "lawful mining operation" means any small scale mining operation that is in full compliance with state and federal laws. (2) A person commits the crime of interfering with a mining operation if the person intentionally: (a) Interferes with a lawful mining operation; or (b) Stops, or causes to be stopped, a lawful mining operation. (3) Interfering with a mining operation is a Class C misdemeanor. [1999 c.354 §6]" Here is the GoPro camera I was using: http://amzn.to/19yYus6

Jackson Gold Mine - Colorado - 2016
This is an impressive and old site. It appears the claim was originally worked in the early 1900’s when the shaft and adit were the sole producers. Trenching was probably done later in the 1940-1950’s. The operation was large enough to have a few buildings, headframe and hoist house.

Fascinating Visit To The “Rogue” Miner’s Gold Mine
We were very fortunate to be afforded the opportunity to visit this historic site as it is certainly not open to the public... Aside from the colorful personality of Mr. Randy Yager, we were also treated to an extensive tour of a rich - and still producing - lode gold mine (And not a dull visit of the “stay behind the white lines” variety that would be found on the tourist circuit either). As viewers of this channel know, it is rare for us to encounter very much in the way of historical mining equipment and artifacts at an abandoned mine. Many abandoned mines have had much of their equipment and other treasures carted away by the miners themselves when the mine was abandoned. Over the following decades, “collectors” carry away pretty much everything else that can be lifted and hauled away… Not at this mine though! At this mine, we get to see what a functioning gold mine looks like – one that was a medium-sized, mine-to-mill operation several decades ago and that now might as well be a living museum from that era. The shower room/work shop/drill room/bunkhouse/compressor room and the mill could use a little paint and some duct tape before they would be in pristine condition again, but we can still see all of the equipment in them as it was when this mine was in full operation and see exactly how things worked back then. I love the underground time, but I found that “moment frozen in time” experience on the surface to be fascinating. You’ve got to think that they were still actively mining here up into the 1960s when gold was $35 an ounce and the miners were able to support themselves on that. So, consider the potential of this mine now if it were to be brought back up to maximum production! With the background noise and different people talking, it can be hard to hear him sometimes, but if you listen carefully, Randy provides a lot of information about this mine. I tried to include as much of him discussing the mine as I could, but I had almost two hours of video that needed to be whittled down to make it digestible for the short attention span of many (but certainly not all) YouTube viewers. It was interesting (to me at least) to hear that the miners had simply tunneled past badly caved sections in the mine rather than deal with the hassle of trying to rehab these sketchy sections. I wasn’t clear if the 3,000+ feet that the adit ran past the waste rock pile where Cory and I climbed up the raise was just caved in one section or if essentially all of it was caved. I believe it was one section, but I’m not certain of that. As you may have heard, aside from the thousands of feet that the main haulage adit kept running, there were also four levels above us in the haulage adit and several levels below us. So, this is a pretty extensive mine. I’d imagine there could be some pretty good stuff to see in these other sections. It would have been wonderful to spend a whole day here, but when you’re someone’s guest, you move at their pace. Thank you again, Cory and Randy, for this adventure. ***** All of these videos are uploaded in HD, so adjust those settings to ramp up the quality! It really does make a difference. You can see the gear that I use for mine exploring here: https://bit.ly/2wqcBDD You can click here for my full playlist of abandoned mines: https://goo.gl/TEKq9L Thanks for watching! ***** Growing up in California’s “Gold Rush Country” made it easy to take all of the history around us for granted. However, abandoned mine sites have a lot working against them – nature, vandals, scrappers and various government agencies… The old prospectors and miners that used to roam our lonely mountains and toil away deep underground are disappearing quickly as well. These losses finally caught our attention and we felt compelled to make an effort to document as many of the ghost towns and abandoned mines that we could before that colorful niche of our history is gone forever. But, you know what? We enjoy doing it! This is exploring history firsthand – bushwhacking down steep canyons and over rough mountains, figuring out the techniques the miners used and the equipment they worked with, seeing the innovations they came up with, discovering lost mines that no one has been in for a century, wandering through ghost towns where the only sound is the wind... These journeys allow a feeling of connection to a time when the world was a very different place. And I’d love to think that in some small way we are paying tribute to those hardy miners that worked these mines before we were even born. So, yes, in short, we are adit addicts… I hope you’ll join us on these adventures! #ExploringAbandonedMines #MineExploring #AbandonedMines #UndergroundMineExploring

2018 - Underground Retail
It's history hidden beneath our feet. Underground retail spaces once filled the downtown streets of many Colorado cities. Whether it's a sunken entrance on a busy retail street or underground stores whose entrances lie hidden in tunnels, these features allowed retailers to fill more space in downtown areas and also to get goods (and customers) to their stores free of the mud and clutter of the surface streets.
Colorado 2013: Mollie Kathleen Gold Mine, Cripple Creek
Coming West to Colorado from Ottumwa, Iowa, arriving with her husband Henry, son Perry and daughter Elizabeth, the Gortner family first settled on North Nevada Street in Colorado. Springs. In the spring of 1891 Mollie's son Perry arrived in the Cripple Creek area employed as a surveyor assigned to map mining claims of this country's newest and overlooked frontier. With all news of the day focused on Cripple Creek's gold. Mollie loaded the family wagon with supplies and joined the next wagon train heading west up Ute Pass to visit her son. After a four day trip, Mollie was relieved to find Perry had completed construction of a half log half canvas field tent. Mollie wasted little time setting up housekeeping. In September of that year (1891), Perry while surveying upper Poverty Gulch, saw a huge herd of elk. Later he told Mollie of the herd so she headed out to see for herself. As she made her way up Poverty Gulch (three hundred yards past Cripple Creek's first gold strike - Bob Womack's Gold King Mine), winded Mollie decided to rest. Looking downward, as she caught her breath, Mollie noticed an interesting rock formation that winked back at her. Using a rock to break off a sample, she could hardly believe her eyes, the outcropping was pure gold laced in quartz. With her heart racing Mollie nonchalantly hid gold samples amongst her clothing, she had to be calm, and there were a number of prospectors in the area. Earlier that day Mollie had mingled with Bob Womack whom had overlooked her find for more than a dozen years prospecting an area he had nicknamed Poverty Gulch. By her determined act, Mollie Kathleen Gortner became the first woman in the Gold Camp to discover gold and strike a claim in her own name. This was clearly a bold move out of step with the times. Most men of the time, only named their horses, jack asses, and mines after their women, it was very uncommon to let a woman claim something of such value. Even after her mine was in production and when visited by the National Geological Survey, it's authors entered their report of the mine being "Discovered by Mr. M.C. Gortner" Mr. Gortner's name was Henry - - - Mollie's name was Mary Catherine Gortner. Mollie Kathleen Gortner Died in 1917. Henry would later die of a broken heart one short year later

Exploring an abandoned 1800s gold mine
One of the several abandoned mine shafts we found high up in the Colorado mountains. Basically undisturbed due to the extreme remote location and difficult access- Mule, horse, on foot or ATV is the only way up here otherwise and it wasn't on our public trail maps.
