Cave Of The Mounds
Cave of the Mounds, a natural limestone cave located near Blue Mounds, Wisconsin, United States, is named for two nearby hills called the Blue Mounds. It is located in the southern slope of the east hill. The cave's beauty comes from its many varieties of mineral formations called speleothems. The Chicago Academy of Sciences considers the Cave of the Mounds to be "the significant cave of the upper Midwest" because of its beauty, and it is promoted as the "jewel box" of major American caves. In 1987, the United States Department of the Interior and the National Park Service designated the cave as a National Natural Landmark. History The limestone from which the cave was carved began forming approximately 488 million years ago, during the Ordovician Period. During this time, much of North America was covered with warm, shallow seas. Over millions of years, calcium carbonate shells from tiny marine organisms accumulated on the sea floor, forming enormous quantities of limeston ...

Wisconsin
Wisconsin () is a state in the upper Midwestern United States. Wisconsin is the 25th-largest state by total area and the 20th-most populous. It is bordered by Minnesota to the west, Iowa to the southwest, Illinois to the south, Lake Michigan to the east, Michigan to the northeast, and Lake Superior to the north. The bulk of Wisconsin's population live in areas situated along the shores of Lake Michigan. The largest city, Milwaukee, anchors its largest metropolitan area, followed by Green Bay and Kenosha, the third- and fourth-most-populated Wisconsin cities respectively. The state capital, Madison, is currently the second-most-populated and fastest-growing city in the state. Wisconsin is divided into 72 counties and as of the 2020 census had a population of nearly 5.9 million. Wisconsin's geography is diverse, having been greatly impacted by glaciers during the Ice Age with the exception of the Driftless Area. The Northern Highland and Western Upland along ...

Ebenezer Brigham
Ebenezer Brigham (April 28, 1789 – September 14, 1861) was a 19th-century American pioneer, businessman, and politician. He was one of the first Americans to explore southwestern Wisconsin and the first permanent settler in present-day Dane County, Wisconsin. A militia officer during the Black Hawk War, he served as commander of Fort Blue Mounds (or Mound Fort) and was active in both the Wisconsin territorial council, and the Wisconsin State Assembly during the 1840s and 1850s. Early life Born in Shrewsbury, Massachusetts, he left his home state for the Northwest Territory, traveling by canoe along the Allegheny River from Olean Point to Pittsburgh, then taking a flatboat down the Ohio River until stopping at Shawneetown. He walked the rest of the way, arriving in St. Louis in 1818. Career Working as a prospector, Brigham followed the Mississippi River by horseback and stayed at Galena in 1822. One of the earliest visitors to the area, he helped miner James Joh ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Flowstone
Flowstones are sheetlike deposits of calcite or other carbonate minerals, formed where water flows down the walls or along the floors of a cave. They are typically found in "solution caves", in limestone, where they are the most common speleothem. However, they may form in any type of cave where water enters that has picked up dissolved minerals. Flowstones are formed via the degassing of vadose percolation waters. Flowstone may also form on manmade structures as a result of calcium hydroxide being leached from concrete, lime or mortar. These secondary deposits created outside the cave environment, which mimic the shapes and forms of speleothems, are classified as " calthemites" and are associated with concrete degradation.Smith, G.K., (2016). “Calcite Straw Stalactites Growing From Concrete Structures”, Cave and Karst Science, Vol.43, No.1, P.4-10, (April 2016), British Cave Research Association, ISSN 1356-191X.

Soda Straw
A soda straw (or simply straw) is a speleothem in the form of a hollow mineral cylindrical tube. They are also known as tubular stalactites. Soda straws grow in places where water leaches slowly through cracks in rock, such as on the roofs of caves. Soda straws in caves rarely grow more than a few millimetres per year and may average one tenth of a millimetre per year.Hill, C A, and Forti, P, (1997). "Speleothem Growth Rates", Cave Minerals of the World, (2nd edition). untsville, Alabama: National Speleological Society Inc.pp 285 - 287 A soda straw can turn into a stalactite if the hole at the bottom is blocked, or if the water begins flowing on the outside surface of the hollow tube. Soda straws can also form outside the cave environment on exposed concrete surfaces as a type of calthemite, growing significantly faster than those formed on rock. Formation These tubes form when calcium carbonate or calcium sulfate dissolved in the water comes out of solution and is de ...

Stalagmite
A stalagmite (, ; from the Greek , from , "dropping, trickling") is a type of rock formation that rises from the floor of a cave due to the accumulation of material deposited on the floor from ceiling drippings. Stalagmites are typically composed of calcium carbonate, but may consist of lava, mud, peat, pitch, sand, sinter, and amberat (crystallized urine of pack rats). The corresponding formation hanging down from the ceiling of a cave is a stalactite. Mnemonics have been developed for which word refers to which type of formation; one is that ''stalactite'' has a C for "ceiling", and ''stalagmite'' has a G for "ground", another is that, as with ants in the pants, the mites go up and the tights (tites) come down. Formation and type Limestone stalagmites The most common stalagmites are speleothems, which usually form in limestone caves. Stalagmite formation occurs only under certain pH conditions within the cavern. They form through deposition of calcium carb ...

Stalactites
A stalactite (, ; from the Greek 'stalaktos' ('dripping') via ''stalassein'' ('to drip') is a mineral formation that hangs from the ceiling of caves, hot springs, or man-made structures such as bridges and mines. Any material that is soluble and that can be deposited as a colloid, or is in suspension, or is capable of being melted, may form a stalactite. Stalactites may be composed of lava, minerals, mud, peat, pitch, sand, sinter, and amberat (crystallized urine of pack rats). A stalactite is not necessarily a speleothem, though speleothems are the most common form of stalactite because of the abundance of limestone caves. The corresponding formation on the floor of the cave is known as a stalagmite. Mnemonics have been developed for which word refers to which type of formation; one is that ''stalactite'' has a C for "ceiling", and ''stalagmite'' has a G for "ground". Another example is that ''stalactites'' "hang on ''T''ight" and ''stalagmites'' "''M''ight gr ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Souvenir
A souvenir (), memento, keepsake, or token of remembrance is an object a person acquires for the memories the owner associates with it. A souvenir can be any object that can be collected or purchased and transported home by the traveler as a memento of a visit. The object itself may have intrinsic value, or be a symbol of experience. Without the owner's input, the symbolic meaning is lost and cannot be articulated. As objects The tourism industry designates tourism souvenirs as commemorative merchandise associated with a location, often including geographic information and usually produced in a manner that promotes souvenir collecting. Throughout the world, the souvenir trade is an important part of the tourism industry serving a dual role, first to help improve the local economy, and second to allow visitors to take with them a memento of their visit, ultimately to encourage an opportunity for a return visit, or to promote the locale to other tourists as a form of word ...

Quarry
A quarry is a type of open-pit mining, open-pit mine in which dimension stone, rock (geology), rock, construction aggregate, riprap, sand, gravel, or slate is excavated from the ground. The operation of quarries is regulated in some jurisdictions to reduce their environmental impact. The word ''quarry'' can also include the underground quarrying for stone, such as Bath stone. Types of rock Types of rock extracted from quarries include: *Chalk *China clay *Scoria, Cinder *Clay *Coal *Construction aggregate (sand and gravel) *Coquina *Diabase *Gabbro *Granite *Gritstone *Gypsum *Limestone *Marble *Ores *Phosphate rock *Quartz *Sandstone *Slate *Travertine Stone quarry Stone quarry is an outdated term for mining construction rocks (limestone, marble, granite, sandstone, etc.). There are open types (called quarries, or open-pit mines) and closed types (Mining, mines and caves). For thousands of years, only hand tools had been used in quarries. In the 18th century, th ...

Blackhawk War
The Black Hawk War was a conflict between the United States and Native Americans led by Black Hawk, a Sauk leader. The war erupted after Black Hawk and a group of Sauks, Meskwakis (Fox), and Kickapoos, known as the "British Band", crossed the Mississippi River, into the U.S. state of Illinois, from Iowa Indian Territory in April 1832. Black Hawk's motives were ambiguous, but he was apparently hoping to reclaim land sold to the United States in the disputed 1804 Treaty of St. Louis. U.S. officials, convinced that the British Band was hostile, mobilized a frontier militia and opened fire on a delegation from the Native Americans on May 14, 1832. Black Hawk responded by successfully attacking the militia at the Battle of Stillman's Run. He led his band to a secure location in what is now southern Wisconsin and was pursued by U.S. forces. Meanwhile, other Native Americans conducted raids against forts and colonies largely unprotected with the absence of the militia. Some Ho ...

Blue Mounds Fort
Fort Blue Mounds, also known as Blue Mounds Fort, was located in Blue Mounds, Dane County, Wisconsin, United States. History The settlement of Blue Mounds was founded in 1828 by Ebenezer Brigham on the south slope of the eastern mound of the Blue Mounds. In 1832, when word arrived that Chief Black Hawk and his 1200 Sauk followers had crossed the Mississippi River, it was decided to build a fort to protect the settlers. On May 10, 1832, the construction of Fort Blue Mounds began with the help of the residents of Blue Mounds, led by the newly promoted Colonel Ebenezer Brigham. The fort was built a mile south of Eastern Mound on the highest part of the open prairie, allowing for a commanding view of the open country for miles. Those who defended the fort were able to see to the east, south, and west, with the mound bounding the northern side of the fort. Word quickly arrived at the settlement of an engagement between Black Hawk's group and the Illinois militia on May 14, 1832. ...

Post Office
A post office is a public facility and a retailer that provides mail services, such as accepting letters and parcels, providing post office boxes, and selling postage stamps, packaging, and stationery. Post offices may offer additional services, which vary by country. These include providing and accepting government forms (such as passport applications), and processing government services and fees (such as road tax, postal savings, or bank fees). The chief administrator of a post office is called a postmaster. Before the advent of postal codes and the post office, postal systems would route items to a specific post office for receipt or delivery. During the 19th century in the United States, this often led to smaller communities being renamed after their post offices, particularly after the Post Office Department began to require that post office names not be duplicated within a state. Name The term "post-office" has been in use since the 1650s, shortly after the leg ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Stagecoach
A stagecoach is a four-wheeled public transport coach used to carry paying passengers and light packages on journeys long enough to need a change of horses. It is strongly sprung and generally drawn by four horses although some versions are drawn by six horses. Commonly used before steam-powered rail transport was available, a stagecoach made long scheduled trips using ''stage stations'' or posts where the stagecoach's horses would be replaced by fresh horses. The business of running stagecoaches or the act of journeying in them was known as staging. Some familiar images of the stagecoach are that of a Royal Mail coach passing through a turnpike gate, a Dickensian passenger coach covered in snow pulling up at a coaching inn, a highwayman demanding a coach to "stand and deliver" and a Wells Fargo stagecoach arriving at or leaving a Wild West town. The yard of ale drinking glass is associated by legend with stagecoach drivers, though it was mainly used for drinking feats ...
