WALSENBURG was called the "City Built on Coal" during the late 19th and early 20th centuries. Exhibits highlight memories of the more than 100 mining camps in Huerfano County which were home to thousands of miners and their families.
LOCATED IN the 1896 Huerfano County Jail, the Walsenburg Mining Museum also has memorabilia from the original jail including a "furnished" cell. See where such notable law-breakers as Bob Ford, the murderer of Jesse James (he killed another man in Walsenburg), and Mary "Mother" Jones, a labor organizer in the 1903-1904 and bloody 1913-1914 coal miners' strikes. Another display shows the opposite side of the labor force with a complete office once belonging to the owner of a coal mining company.
THE MINING Museum displays vintage photographs of the miners, their families, homes and camps. Also on display are maps and charts, miner's personal gear and belongings, tools and equipment. One map highlights the world origins of the unfortunate miners killed in local mines. There also is much genealogical material for those searching for their roots. A gift shop on the premises offers books, maps, and other informational materials as well as souvenirs and keepsakes.
The Holly Leaf Miner is a small fly with larvae that cause discoloured blotches by feeding inside holly leaves. Grubs of the holly leaf miner tunnel inside the leaves. There is one generation a year, and the adult flies lay eggs on the new foliage in May to June. When the larvae have completed their feeding in the following spring, they pupate inside the leaf mines.
There is plenty of evidence of their mining work at Warley Place Nature Reserve!

Pearce, Arizona is a mining ghost town named for Cornishman James Pearce, miner and cattleman, who discovered gold nearby at what became the Commonwealth Mine in 1894. The Pearce Post Office was established on March 6, 1896. The railroad station opened in 1903. By 1919, Pearce had a population of 1,500. The town declined in the 1930s, and became almost a ghost in the late 1940s, when the mine closed for the last time.
The Commonwealth Mine became one of Arizona's major silver producers. Over 1,000,000 tons of ore were produced from 1895 to 1942. There are about 20 miles of underground workings. The mine produced about $8 million worth of silver and $2.5 million in gold at a time when silver was priced around 50 cents an ounce, and gold was $20 an ounce.

Risca Colliery's two shafts were sunk in 1875 with coal production starting in 1878. On 15 July 1880 an explosion killed 120 men and boys due to the miners preferring to use older "Clanny" lamps to the new Davy safety lamps. Clanny lamps were subsequently banned in mines. An explosion in 1860 at the nearby Black Vein Colliery had already claimed the lives of 146 men and boys. The colliery closed in 1967 and is now the site of an industrial estate.
The chapel was built in 1858 to provide English language services for the influx of "foreign" workers to the expanding industries. It was enlarged in 1875.
Regulations governing mining operations are specific to national and jurisdictional regulations and local circumstances. While their variation precludes an extensive review in this report, given that regulatory failures and inadequacies contribute to tailings dam failures (Golder and Associates 2016), an international regulatory systems review would be beneficial in improving tailings management.
Tailings Dam failures are a shared responsibility, caused as much by regulatory as management failure. In cases of catastrophic failures, the regulatory system has failed to ensure good design, and to implement, monitor and enforce adequate standards. As ICOLD determined, these failures are frequently human-caused. Regulatory systems with multiple, independent checks are required to ensure standards and detect impending failures.
A regulatory system, for example, should cover the civil works, environmental performance and risk calculations associated with tailings storage facilities. They should also stipulate financial requirements for perpetual management of waste or a requirement for rehabilitation to a level that enables the site to be safely relinquished for reuse for non-mining purposes. While the practical requirements for mine waste planning, treatment, storage, monitoring and management are highly specific to the mine location, some higher-level issues are widely applicable. The figure illustrates an evolution of tailings management, from proponent-driven to a gradual increase in regulations for a more inclusive approach that would reduce risk for all stakeholders.

This camera was an experiment in a smaller aperture, but my calculations for exposure are consistently making underexposed photographs, possibly an error in the chart I use.
So the story goes from the guy with all these hidden treasures is that this is a stamping mill and according to him he had a partner at one time and the orginal mill deteriorated then with some help they rebuilt it. That's what he said anyway. Then something about a mine hole they had covered up whenthis old guy came up seen what they did and had a total fit. That's the way the story went.
