Yule Marble is a marble of metamorphosed limestone found only in the Yule Creek Valley, in the West Elk Mountains of Colorado, 2.8 miles (4.5 km) southeast of the town of Marble, Colorado.[1] First discovered in 1873, it is quarried today inside a mountain at 9,300 feet (2,800 m) above sea level, in contrast to most marble, which is quarried from an open pit and at much lower elevations.
Eureka is a museum of mining history. Situated on highway 50 about halfway between Austin and Ely, few other towns offer as much to the curious visitor as does Eureka. The year 1864 saw the discovery of lead-silver deposits as spectacular as any in the country. But there was a problem. Bi-metallic ore required refining methods and techniques not yet developed. The first plant built in 1869 was a failure. Another was built that was more successful and was the forerunner of even more advanced methods. The boom then began in earnest and continued until there were nearly 10,000 people in the town. About the time production began to decline, a railroad was brought into Eureka. Because of the town's central location in the state, it became a railhead for the whole area.
Archaeological evidence, such as arrow heads and stone dart tips, has found that there was prehistoric and historic occupation by Native American peoples. The earliest occupation was about 9,000 years ago.[3] Artifacts found represent the Apishapa culture, Cody complex and Duncan complex.[1] The clay was used in prehistoric and historic times to create and paint pottery and as paint for ceremonial purposes. The selenite clay was used for arrowheads. The "channels" were used to herd buffalo into a gulch where they could be easily hunted with bows and arrows.[3][4] In the 1800s Euro-American people settled in the park property.[3]
The Calhan Paint Mines Archaeological District was designated by the National Park Service. The land is protected by the El Paso County Parks Department, with funding by the State Historical Fund for master planning and an archaeological survey.[3]
In the area of Cripple Creek, Co. - a gold mine with what look's like a transport van at a upper level then another one lower down.

Visiting from the Statfold Barn railway, Cegin awaits departure from Threlkeld. Liassic, having brought the train in, awaits it's next run
EMCO 7202 (ALCO RS11) loading in Erie's Area 1 pit. Nine cars with 85 long tons in each. The shovel is a Bucyrus 190B

Not even going to attempt ID, although I suspect it's an Andrena, but then I'll be wrong! Lol! Another angle below (viewable large).

A short stroll out of town is the mill site of Custer, in fall it sits on a hillside surrounded by golden aspen.
The Drenner E-51, while highly outdated now, pioneered the now-common "isolation" method of mining, in which the surrounding rock is vaporized using low-intensity bolts and the material is gathered via tractor beam and sent to the aft processing unit.
This craft must be used in tandem with a shipping barge, as it has no internal holds of its own.

Mining is a global industry that underpins industrial development in many regions. It is a key sector not only because it is the source of essential raw materials, but also because it potentially leads to economic and social development, often in remote and poorly developed areas, due to its importance in national accounts, level of employment and influence of international markets, etc. Mining activities can also cause severe environmental degradation because of its location (almost all conceivable places, often with insufficient infrastructure), size and timescale. Potential negative impacts of mining operations include: * Energy and water consumption * Air, water and land pollution * Landscape alteration * Soil erosion * Destruction of river banks * Health & safety nuisance.

I discovered an admirer-er, that's not a stalker , says I've been trying to figure out what draws your interest, I saw you open your camera case, am enjoying my new adventure camera experience, well the conversation went like this,, They went to a lengthy process of replication late 1800 - early 1900, however some omissions, evidence, construction material, laminated wood products, electrified Kerosene lamp and door pulls knobs and such. Wow ! you are a history buff as well ! Have had experience in building and repair furniture, in DNA
Another abandoned mining locomotive from the same mine as the locos in the previous picture. This type is obviously a more advanved design.
The Mining Tanker is built to go into in low underground tunnels to provide refueling needs for mining equipment.
This model was built for both the Lego Space Discord's Febroverary build challenge, as well as the Old Gray Bricks Discord's Color My Bricks contest.
August 6th - another shot with hours in the planning - the right weather with time to stop. This is an engine house that has been converted to a holiday home. It is suspiciously empty this season. I have added a clarity app only - spent a while doing changes but came back to this.
Nevadaville was a gold-mining town in Gilpin County, Colorado, United States. It was also known in the 1860s and 1870s as Nevada City. The post office at Nevadaville was called the Bald Mountain post office, to avoid confusion with other Nevadas and Nevadavilles. The community is now largely a ghost town, although not completely deserted. The Nevadaville Masonic Temple that started in 1861 still holds regular meetings. Nevadaville started in 1859, soon after John H. Gregory found the first lode gold in what is now Colorado. At the time, the townsite was in western Kansas Territory. The town grew to house the miners working the Burroughs lode and the Kansas lode. The population was predominantly Irish.[1]
The Mariscal Mine was a mercury mining operation in the southern part of what is now Big Bend National Park. The mine operated until World War II, producing nearly a quarter of all the mercury produced in the U.S. from 1900 to 1943. This is now on the National Register of Historic Places but is very difficult to visit on account of its remoteness.
The brick building on the left side of the image contained the ovens in which the operation baked the ore to extract the mercury. Over the years, the bricks became so permeated with mercury that visitors are advised to not touch the bricks due to the possibility of heavy metal poisoning. Otherwise, visitors can wander all over the area. There is a mine entrance on the far side of the building.
In a little while I will be posting short series taken in an underground mine. This is a redundant machine that, while no longer used, retains some character.
A screen grab of a dragline in action mining phosphate rock in Polk County. The Polk County History Center in Bartow has a section featuring one of the major sources of Central Florida’s prosperity. The source material are layers of bones and shells many millions of years old, the sediment from prehistoric times when the area was part of a large sea. The rock is refined to become a primary fertilizer material, via the addition of sulphuric acid to create phosphoric acid. Central Florida ranks second only to Morocco in phosphate rock deposits, which are a non-renewable resource.
It was my job as a fertilizer market analyst that first brought me to Florida in the mid-1980s. That might not seem the most enticing of careers, but in common with many colleagues and friends, it proved very rewarding and fulfilling. I lasted some 31 years in the business. I always enjoyed visits to the mines and processing plants, which included observing the extraction of the raw material from within a dragline cab.
The operation makes heavy environmental demands, including water use for the rock refinement. The phosphoric acid production process also creates by-product gypsum, which in the absence of any permitted commercial use must be dumped in high-maintenance stacks. Once the mine is depleted, the mining company is obligated to restore the landscape to its original state.
