Trojan, South Dakota
Trojan, also known as Portland, is a ghost town in the Black Hills of Lawrence County, South Dakota. It was established by and named after the Trojan Mining Company. Naming Trojan got its name from its founding company, the Trojan Mining Company. Its earlier name, Portland, came from the nearby Portland Mine. History As early as 1877, gold was known to be inside Bald Mountain and Green Mountain, located in the Trojan area. By 1900, many claims had been sorted out into only a few, and by 1911, the Trojan Mining Company held the majority of them. In 1928, the Trojan Mining Company was bought out by the Bald Mountain Mining Company. However, by the 1950s, the ore in the Trojan mines was only being sold for $6 per ton, which did not provide enough of a profit to keep the mines in operation. Steel and powder, which were required to run the mines, increased in price, but gold remained $35 an ounce, which it had been since 1934. In 1959, all operations shut down and every mining buildi ...

Mountain Time Zone
The Mountain Time Zone of North America keeps time by subtracting seven hours from Coordinated Universal Time (UTC) when standard time ( UTC−07:00) is in effect, and by subtracting six hours during daylight saving time ( UTC−06:00). The clock time in this zone is based on the mean solar time at the 105th meridian west of the Greenwich Observatory. In the United States, the exact specification for the location of time zones and the dividing lines between zones is set forth in the Code of Federal Regulations at 49 CFR 71. In the United States and Canada, this time zone is generically called Mountain Time (MT). Specifically, it is Mountain Standard Time (MST) when observing standard time, and Mountain Daylight Time (MDT) when observing daylight saving time. The term refers to the Rocky Mountains, which range from British Columbia to New Mexico. In Mexico, this time zone is known as the or ("Pacific Zone"). In the US and Canada, the Mountain Time Zone is to the east of the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Black Elk Peak (formerly known as Harney Peak), which rises to , is the range's highest summit. The Black Hills encompass the Black Hills National Forest. The name of the hills in Lakota is ', meaning “the heart of everything that is." The Black Hills are considered a holy site. The hills are so called because of their dark appearance from a distance, as they are covered in evergreen trees. Native Americans have a long history in the Black Hills and consider it a sacred site. After conquering the Cheyenne in 1776, the Lakota took the territory of the Black Hills, which became central to their culture.

Cyanide Plant Of Trojan Mining Company In Trojan, South Dakota (1919)
Cyanide is a naturally occurring, rapidly acting, toxic chemical that can exist in many different forms. In chemistry, a cyanide () is a chemical compound that contains a functional group. This group, known as the cyano group, consists of a carbon atom triple-bonded to a nitrogen atom. In inorganic cyanides, the cyanide group is present as the anion . Soluble salts such as sodium cyanide (NaCN) and potassium cyanide (KCN) are highly toxic. Hydrocyanic acid, also known as hydrogen cyanide, or HCN, is a highly volatile liquid that is produced on a large scale industrially. It is obtained by acidification of cyanide salts. Organic cyanides are usually called nitriles. In nitriles, the group is linked by a covalent bond to carbon. For example, in acetonitrile (), the cyanide group is bonded to methyl (). Although nitriles generally do not release cyanide ions, the cyanohydrins do and are thus rather toxic. Bonding The cyanide ion is isoelectronic with carbon monoxide a ...

Gold
Gold is a chemical element with the symbol Au (from la, aurum) and atomic number 79. This makes it one of the higher atomic number elements that occur naturally. It is a bright, slightly orange-yellow, dense, soft, malleable, and ductile metal in a pure form. Chemically, gold is a transition metal and a group 11 element. It is one of the least reactive chemical elements and is solid under standard conditions. Gold often occurs in free elemental ( native state), as nuggets or grains, in rocks, veins, and alluvial deposits. It occurs in a solid solution series with the native element silver (as electrum), naturally alloyed with other metals like copper and palladium, and mineral inclusions such as within pyrite. Less commonly, it occurs in minerals as gold compounds, often with tellurium (gold tellurides). Gold is resistant to most acids, though it does dissolve in aqua regia (a mixture of nitric acid and hydrochloric acid), forming a soluble tetrachloroaurate anion. Gold is ...

With an elevation of above sea level, it is the most prominent peak in the Northern Black Hills area, and the sixth highest summit in the range; the tallest is Black Elk Peak (formerly Harney Peak) at . The mountain was named for Alfred Howe Terry, who had explored the area. It was first used as a ski area in 1936 by the Bald Mountain Ski Club when a rope tow was installed. The first chair lift was installed in 1952 and began operation in 1954. The ski area has since seen many upgrades in chair lifts, trails, and accommodations. Currently, there are three "high speed" chairlifts (Kussy, Surprise, and Gold Corp Express, (or Blue, Yellow, and Red, respectively), which provide access to most of the runs on the mountain in a matter of minutes, as well as one traditional-speed lift ...
