Helvetia, Arizona
Helvetia is a ghost town in Pima County, Arizona, United States that was settled in 1891 and abandoned in the early 1920s. Helvetia is an ancient name for Switzerland. History Helvetia was founded in 1891 for the settlement of workers from the surrounding copper mines. At its peak the city had 300 inhabitants, of which most were Mexicans. At one point, Helvetia had a public school (run by School District No. 14, Pima County). In 1911, the mines closed, due to low commodity prices. The post office, which had opened on December 12, 1899, closed on December 31, 1921, marking the end of the town. The 1967 western film '' Hombre'' was shot in Helvetia. Today There is not much left of Helvetia to see, simply a pair of foundation walls rising above a floor, the ruins of the smelter, and the cemetery. In the vicinity there are slag heaps and shafts from the mines. Although the town is gone, there are several homes in the immediate area that are still in use, including the Helvetia Ra ...

Molybdenum
Molybdenum is a chemical element with the symbol Mo and atomic number 42 which is located in period 5 and group 6. The name is from Neo-Latin ''molybdaenum'', which is based on Ancient Greek ', meaning lead, since its ores were confused with lead ores. Molybdenum minerals have been known throughout history, but the element was discovered (in the sense of differentiating it as a new entity from the mineral salts of other metals) in 1778 by Carl Wilhelm Scheele. The metal was first isolated in 1781 by Peter Jacob Hjelm. Molybdenum does not occur naturally as a free metal on Earth; it is found only in various oxidation states in minerals. The free element, a silvery metal with a grey cast, has the sixth-highest melting point of any element. It readily forms hard, stable carbides in alloys, and for this reason most of the world production of the element (about 80%) is used in steel alloys, including high-strength alloys and superalloys. Most molybdenum compounds have low solubili ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Populated Places Established In 1891
Population typically refers to the number of people in a single area, whether it be a city or town, region, country, continent, or the world. Governments typically quantify the size of the resident population within their jurisdiction using a census, a process of collecting, analysing, compiling, and publishing data regarding a population. Perspectives of various disciplines Social sciences In sociology and population geography, population refers to a group of human beings with some predefined criterion in common, such as location, race, ethnicity, nationality, or religion. Demography is a social science which entails the statistical study of populations. Ecology In ecology, a population is a group of organisms of the same species who inhabit the same particular geographical area and are capable of interbreeding. The area of a sexual population is the area where inter-breeding is possible between any pair within the area and more probable than cross-breeding with i ...

Ghost Towns In Arizona
A ghost is the soul or spirit of a dead person or animal that is believed to be able to appear to the living. In ghostlore, descriptions of ghosts vary widely from an invisible presence to translucent or barely visible wispy shapes, to realistic, lifelike forms. The deliberate attempt to contact the spirit of a deceased person is known as necromancy, or in spiritism as a ''séance''. Other terms associated with it are apparition, haunt, phantom, poltergeist, shade, specter or spectre, spirit, spook, wraith, demon, and ghoul. The belief in the existence of an afterlife, as well as manifestations of the spirits of the dead, is widespread, dating back to animism or ancestor worship in pre-literate cultures. Certain religious practices—funeral rites, exorcisms, and some practices of spiritualism and ritual magic—are specifically designed to rest the spirits of the dead. Ghosts are generally described as solitary, human-like essences, though stories of ghostly armies and th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Former Populated Places In Pima County, Arizona
A former is an object, such as a template, gauge or cutting die, which is used to form something such as a boat's hull. Typically, a former gives shape to a structure that may have complex curvature. A former may become an integral part of the finished structure, as in an aircraft fuselage, or it may be removable, being using in the construction process and then discarded or re-used. Aircraft formers Formers are used in the construction of aircraft fuselage, of which a typical fuselage has a series from the nose to the empennage, typically perpendicular to the longitudinal axis of the aircraft. The primary purpose of formers is to establish the shape of the fuselage and reduce the column length of stringers to prevent instability. Formers are typically attached to longerons, which support the skin of the aircraft. The "former-and-longeron" technique (also called stations and stringers) was adopted from boat construction, and was typical of light aircraft built until the ad ...

Larcena Pennington Page
Larcena Pennington Page (January 10, 1837 – March 31, 1913), born Larcena Ann Pennington, was an American pioneer known for surviving a kidnapping by Apache as a young married woman of 23 years old in present-day Arizona. Left for dead and unable to stand, she crawled over the next sixteen days to reach safety. After her kidnapping, Larcena was indirectly involved in several other incidents with Apache. Much of her family died during her life as a result of native attacks or from infectious disease on the frontier. Early life Born Larcena Ann Pennington, in Nashville, Tennessee, she was the daughter of Elias and Julia Ann Pennington. One of 12 children, she had seven sisters and four brothers. Her father, Elias, was the son of Elijah Pennington, a soldier who served under General George Washington at Valley Forge during the American Revolutionary War.

List Of Ghost Towns In Arizona
This is a partial list of ghost towns in Arizona in the United States. Most ghost towns in Arizona are former mining boomtowns that were abandoned when the mines closed. Those not set up as mining camps often became mills or supply points supporting nearby mining operations. Conditions Ghost towns can include sites in various states of disrepair and abandonment. Some sites no longer have any trace of buildings or civilization and have reverted to empty land. Other sites are unpopulated but still have standing buildings. Still others may support full-time residents, though usually far less than at their historical peak, while others may now be museums or historical sites. For ease of reference, the sites listed here are placed into one of the following general categories. ;Barren site * Site is no longer in existence * Site has been destroyed, covered with water, or reverted to empty land * May have a few difficult to find foundations/footings at most ;Neglected site * Little mo ...

Malachite
Malachite is a copper carbonate hydroxide mineral, with the formula Cu2CO3(OH)2. This opaque, green-banded mineral crystallizes in the monoclinic crystal system, and most often forms botryoidal, fibrous, or stalagmitic masses, in fractures and deep, underground spaces, where the water table and hydrothermal fluids provide the means for chemical precipitation. Individual crystals are rare, but occur as slender to acicular prisms. Pseudomorphs after more tabular or blocky azurite crystals also occur. Etymology and history The stone's name derives (via la, molochītis, frm, melochite, and Middle English ''melochites'') from Greek Μολοχίτης λίθος ''molochites lithos'', "mallow-green stone", from μολόχη ''molochē'', variant of μαλάχη ''malāchē'', "mallow". The mineral was given this name due to its resemblance to the leaves of the mallow plant. Malachite was mined from deposits near the Isthmus of Suez and the Sinai as early as 4000 BCE. It wa ...

Azurite
Azurite is a soft, deep-blue copper mineral produced by weathering of copper ore deposits. During the early 19th century, it was also known as chessylite, after the Type locality (geology), type locality at Chessy, Rhône, Chessy-les-Mines near Lyon, France. The mineral, a basic carbonate with the chemical formula Cu3(CO3)2(OH)2, has been known since ancient times, and was mentioned in Pliny the Elder's ''Natural History (Pliny), Natural History'' under the Greek name (κυανός: "deep blue," root of English ''cyan'') and the Latin name ''caeruleum''. Since antiquity, azurite's exceptionally deep and clear blue has been associated with low-humidity desert and winter skies. The modern English name of the mineral reflects this association, since both ''azurite'' and ''Azure (color), azure'' are derived via Arabic language, Arabic from the Persian language, Persian (لاژورد), an area known for its deposits of another deep-blue stone, lapis lazuli ("stone of azure").
