Galena, Illinois
Galena is the largest city in Jo Daviess County, Illinois, United States, and its county seat. It had a population of 3,308 at the 2020 United States census, 2020 census. A section of the city is listed on the National Register of Historic Places as the Galena Historic District. The city is named for the mineral galena, which was in the ore that formed the basis for the region's early lead mining economy. Native Americans in the United States, Native Americans, primarily Meskwaki, Ho-Chunk, Sauk people, Sauk, and Menominee had mined galena in the area for more than a thousand years before European Americans settled in the area. Owing to these deposits, Galena was the site of the first major mineral rush in the United States. By 1828, the population was estimated at 10,000, rivaling the population of Chicago at the time. Galena developed as the largest steamboat hub on the Mississippi River north of St. Louis. Galena was the home of Ulysses S. Grant and eight other American Civil ...

Galena
Galena, also called lead glance, is the natural mineral form of lead(II) sulfide (PbS). It is the most important ore of lead and an important source of silver. Galena is one of the most abundant and widely distributed sulfide minerals. It crystallizes in the Cubic (crystal system), cubic crystal system often showing octahedral forms. It is often associated with the minerals sphalerite, calcite and fluorite. As a pure specimen held in the hand, under standard temperature and pressure, galena is insoluble in water and so is almost non-toxic. Handling galena under these specific conditions (such as in a museum or as part of geology instruction) poses practically no risk; however, as lead(II) sulfide is reasonably reactive in a variety of environments, it can be highly toxic if swallowed or inhaled, particularly under prolonged or repeated exposure. Occurrence Galena is the main ore of lead, used since ancient times, since lead can be smelted from galena in an ordinary wood fire. G ...

Havana Hopewell Culture
The Havana Hopewell culture were a Hopewellian people who lived in the Illinois River and Mississippi River valleys in Iowa, Illinois, and Missouri from 200 BCE to 400 CE. Hopewell Interaction Sphere The Hopewell Exchange system began in the Ohio and Illinois River Valleys around 300 BCE. The culture is referred to more as a system of interaction among a variety of societies than as a single society or culture. The central Illinois River Valley was home to one particular complex, the Havana Hopewell culture. Havana Hopewell sites have been found in Illinois, northwest Indiana, southwest Michigan, southern Wisconsin, and Minnesota and northeast Iowa. Hopewell trading networks were quite extensive, with obsidian from the Yellowstone area, copper from Lake Superior, and shells from the Gulf Coast. Havana Hopewell sites Toolesboro Mound Group The Toolesboro Mound Group in Louisa County, Iowa included a large octagonal earthen enclosure that covered several acres; earthworks of th ...

Lead
Lead () is a chemical element; it has Chemical symbol, symbol Pb (from Latin ) and atomic number 82. It is a Heavy metal (elements), heavy metal that is density, denser than most common materials. Lead is Mohs scale, soft and Ductility, malleable, and also has a relatively low melting point. When freshly cut, lead is a shiny gray with a hint of blue. It tarnishes to a dull gray color when exposed to air. Lead has the highest atomic number of any stable nuclide, stable element and three of its isotopes are endpoints of major nuclear decay chains of heavier elements. Lead is a relatively unreactive post-transition metal. Its weak metallic character is illustrated by its Amphoterism, amphoteric nature; lead and lead oxides react with acids and base (chemistry), bases, and it tends to form covalent bonds. Lead compounds, Compounds of lead are usually found in the +2 oxidation state rather than the +4 state common with lighter members of the carbon group. Exceptions are mostly limited ...

Lead(II) Sulfide
Lead(II) sulfide (also spelled '' sulphide'') is an inorganic compound with the formula Pb S. Galena is the principal ore and the most important compound of lead. It is a semiconducting material with niche uses. Formation, basic properties, related materials Addition of hydrogen sulfide or sulfide salts to a solution containing a lead salt, such as PbCl2, gives a black precipitate of lead sulfide. : Pb2+ + H2S → PbS↓ + 2 H+ This reaction is used in qualitative inorganic analysis. The presence of hydrogen sulfide or sulfide ions may be tested using "lead acetate paper." Like the related materials PbSe and PbTe, PbS is a semiconductor. In fact, lead sulfide was one of the earliest materials to be used as a semiconductor. Lead sulfide crystallizes in the sodium chloride motif, unlike many other IV-VI semiconductors. Since PbS is the main ore of lead, much effort has focused on its conversion. A major process involves smelting of PbS followed by reduction of the re ...

American Civil War
The American Civil War (April 12, 1861May 26, 1865; also known by Names of the American Civil War, other names) was a civil war in the United States between the Union (American Civil War), Union ("the North") and the Confederate States of America, Confederacy ("the South"), which was formed in 1861 by U.S. state, states that had Secession in the United States, seceded from the Union. The Origins of the American Civil War, central conflict leading to war was a dispute over whether Slavery in the United States, slavery should be permitted to expand into the western territories, leading to more slave states, or be prohibited from doing so, which many believed would place slavery on a course of ultimate extinction. Timeline of events leading to the American Civil War, Decades of controversy over slavery came to a head when Abraham Lincoln, who opposed slavery's expansion, won the 1860 presidential election. Seven Southern slave states responded to Lincoln's victory by seceding f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Steamboat
A steamboat is a boat that is marine propulsion, propelled primarily by marine steam engine, steam power, typically driving propellers or Paddle steamer, paddlewheels. The term ''steamboat'' is used to refer to small steam-powered vessels working on lakes, rivers, and in short-sea shipping. The development of the steamboat led to the larger steamship, which is a seaworthy and often ocean-going ship. Steamboats sometimes use the ship prefix, prefix designation SS, S.S. or S/S (for 'Screw Steamer') or PS (for 'Paddle Steamer'); however, these designations are most often used for steamships. Background Limitations of the Newcomen steam engine The first steamboat designs used Newcomen atmospheric engine, Newcomen steam engines. These engines were large, heavy, and produced little power, which resulted in an unfavorable power-to-weight ratio. The heavy weight of the Newcomen engine required a structurally strong boat, and the reciprocating motion of the engine beam required a compli ...

Menominee
The Menominee ( ; meaning ''"Menominee People"'', also spelled Menomini, derived from the Ojibwe language word for "Wild Rice People"; known as ''Mamaceqtaw'', "the people", in the Menominee language) are a federally recognized tribe of Native Americans officially known as the Menominee Indian Tribe of Wisconsin. Their land base is the Menominee Indian Reservation in Wisconsin. Their historic territory originally included an estimated in present-day Wisconsin and the Upper Peninsula of Michigan. The tribe currently has about 8,700 members. Federal recognition of the tribe was terminated in the 1960s under policy of the time which stressed assimilation. During that period, they brought what has become a landmark case in Indian law to the United States Supreme Court, in '' Menominee Tribe v. United States'' (1968), to protect their treaty hunting and fishing rights. The Wisconsin Supreme Court and the United States Court of Claims had drawn opposing conclusions about ...
