Copperas
Iron(II) sulfate (British English: iron(II) sulphate) or ferrous sulfate denotes a range of salts with the formula Fe SO4·''x''H2O. These compounds exist most commonly as the heptahydrate (''x'' = 7) but several values for x are known. The hydrated form is used medically to treat iron deficiency, and also for industrial applications. Known since ancient times as copperas and as green vitriol (vitriol is an archaic name for sulfate), the blue-green heptahydrate (hydrate with 7 molecules of water) is the most common form of this material. All the iron(II) sulfates dissolve in water to give the same aquo complex e(H2O)6sup>2+, which has octahedral molecular geometry and is paramagnetic. The name copperas dates from times when the copper(II) sulfate was known as blue copperas, and perhaps in analogy, iron(II) and zinc sulfate were known respectively as green and white copperas. It is on the World Health Organization's List of Essential Medicines. In 2020, it was the 116t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ledges State Park
Ledges State Park is a state park of Iowa, USA, located approximately south of the city of Boone. The park contains a sandstone gorge carved by Pea's Creek, a tributary of the Des Moines River. The gorge is deep in places, with concretions jutting from the cliffs. Background The area was designated one of the first of Iowa's state parks in 1924. The lowland areas of the park are regularly flooded by the Des Moines River. In the 1970s, the state created a dam to form Saylorville Lake on the Des Moines River. This action has resulted in repeated flooding of low-lying areas of the park for decades. A group called The Iowa Citizens to Save Ledges State Park was organized in 1972 in protest of the proposed Saylorville Dam. Its primary objective was to alleviate and/or minimize the harmful effects on Ledges State Park by the Saylorville Lake Project of the U.S. Army Corps of Engineers. There were numerous conservation groups affiliated with the group, including the Ames Reservoir ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Backbone State Park
Backbone State Park is Iowa's oldest state park, dedicated in 1919. Located in the valley of the Maquoketa River, it is approximately three miles (5 km) south of Strawberry Point in Delaware County. It is named for a narrow and steep ridge of bedrock carved by a loop of the Maquoketa River originally known as the ''Devil's Backbone''. The initial were donated by E.M. Carr of Lamont, Iowa. Backbone Lake Dam, a relatively low dam built by the Civilian Conservation Corps (CCC) in the 1930s, created Backbone Lake. The CCC constructed a majority of trails and buildings which make up the park. History The area of the Devil's Backbone was a favorite of natural scientists such as W.J. McGee, Thomas Macbride, and Samuel Calvin who visited it to study its ancient geologic formations. with Edward M. Carr bought in the 1890s to protect the Backbone Ridge from destruction. MacBride and members of the Iowa Park and Forestry Association thought of it as a prime location for a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Louis Hennepin
Father Louis Hennepin, O.F.M. baptized Antoine, (; 12 May 1626 – 5 December 1704) was a Belgian Roman Catholic priest and missionary of the Franciscan Recollet order (French: ''Récollets'') and an explorer of the interior of North America. Biography Antoine Hennepin was born in Ath in the Spanish Netherlands (present-day Hainaut, Belgium). In 1629, while he was living in the town of Béthune, it was captured by the army of Louis XIV of France. Henri Joulet, who accompanied Hennepin and wrote his own journal of their travels, called Hennepin a Fleming (a native of Flanders), although Ath was and still is a Romance-speaking area found in present-day Wallonia. Hennepin joined the Franciscans, and preached in Halles (Belgium) and in Artois. He was then put in charge of a hospital in Maestricht. He was also briefly an army chaplain. At the request of Louis XIV, the Récollets sent four missionaries to New France in May 1675, including Hennepin, accompanied by René Rob ...

Latin
Latin (, or , ) is a classical language belonging to the Italic branch of the Indo-European languages. Latin was originally a dialect spoken in the lower Tiber area (then known as Latium) around present-day Rome, but through the power of the Roman Republic it became the dominant language in the Italian region and subsequently throughout the Roman Empire. Even after the fall of Western Rome, Latin remained the common language of international communication, science, scholarship and academia in Europe until well into the 18th century, when other regional vernaculars (including its own descendants, the Romance languages) supplanted it in common academic and political usage, and it eventually became a dead language in the modern linguistic definition. Latin is a highly inflected language, with three distinct genders (masculine, feminine, and neuter), six or seven noun cases (nominative, accusative, genitive, dative, ablative, and vocative), five declensions, four verb conjuga ...

Buffalo Jump
A buffalo jump, or sometimes bison jump, is a cliff formation which Indigenous peoples of North America historically used to hunt and kill plains bison in mass quantities. The broader term game jump refers to a man-made jump or cliff used for hunting other game, such as reindeer. Method of the hunt Hunters herded the bison and drove them over the cliff, breaking their legs and rendering them immobile. Tribe members waiting below closed in with spears and bows to finish the kills. The Blackfoot people called the buffalo jumps "pishkun", which loosely translates as "deep blood kettle". This type of hunting was a communal event that occurred as early as 12,000 years ago. They believed that if any buffalo escaped these killings then the rest of the buffalo would learn to avoid humans, which would make hunting even harder. Buffalo jump sites are often identified by rock cairns, which were markers designating "drive lanes", by which bison would be funneled over the cliff. These d ...

American Bison
The American bison (''Bison bison'') is a species of bison native to North America. Sometimes colloquially referred to as American buffalo or simply buffalo (a different clade of bovine), it is one of two extant species of bison, alongside the European bison. Its historical range, by 9000 BC, is described as the great bison belt, a tract of rich grassland that ran from Alaska to the Gulf of Mexico, east to the Atlantic Seaboard (nearly to the Atlantic tidewater in some areas) as far north as New York, south to Georgia and, according to some sources, further south to Florida, with sightings in North Carolina near Buffalo Ford on the Catawba River as late as 1750. Once roaming in vast herds, the species nearly became extinct by a combination of commercial hunting and slaughter in the 19th century and introduction of bovine diseases from domestic cattle. With a population in excess of 60 million in the late 18th century, the species was culled down to just 541 animals by 1889. ...

Settler
A settler is a person who has human migration, migrated to an area and established a permanent residence there, often to colonize the area. A settler who migrates to an area previously uninhabited or sparsely inhabited may be described as a pioneer. Settlers are generally from a Sedentism, sedentary culture, as opposed to nomads, nomadic peoples who may move settlements seasonally, within traditional territories. Settlement sometimes relies on dispossession of already established populations within the contested area, and can be a very violent process. Sometimes settlers are backed by governments or large countries. Settlements can prevent native people from continuing their work. Historical usage One can witness how settlers very often occupied land previously residents to long-established peoples, designated as Indigenous peoples, Indigenous (also called "natives", "Aborigines" or, in the Americas, "Indians").

Szomolnokite
Szomolnokite (Fe2+SO4·H2O) is a monoclinic iron sulfate mineral forming a complete solid solution with magnesium end-member kieserite (MgSO4·H2O). In 1877 szomolnokite's name was derived by Joseph Krenner from its type locality of oxidized sulfide ore containing iron in Szomolnok, Slovakia (Hungary at the time). As of mid-January 2020 the only continent on which szomolnokite has not been found and reported is Antarctica. At room temperature szomolnokite is stable up to a pressure of 6.2 GPa, and then transforms into triclinic 180px, Triclinic (a ≠ b ≠ c and α ≠ β ≠ γ ) In crystallography, the triclinic (or anorthic) crystal system is one of the 7 crystal systems.

Halotrichite
Halotrichite, also known as ''feather alum'', is a highly hydrated sulfate of aluminium and iron. Its chemical formula is FeAl2(SO4)4·22H2O. It forms fibrous monoclinic crystals. The crystals are water-soluble. It is formed by the weathering and decomposition of pyrite commonly near or in volcanic vents. The locations of natural occurrences include: the Atacama Desert, Chile; Dresden in Saxony, Germany; San Juan County, Utah; Iceland and Mont Saint-Hilaire, Canada. The name is from Latin: ''halotrichum'' for salt hair which accurately describes the precipitate/evaporite mineral. ;Gallery File:Halotrichite Hydrous iron aluminum sulfate Corral, California 3009.jpg, Halotrichite from California File:Halotrichite-179634.jpg, Halotrichite from the abandoned Golden Queen mine on Soledad Mountain south of Mojave, California Mojave (formerly Mohave) is an Unincorporated area, unincorporated community in Kern County, California, United States.
