Niagara Cave
Niagara Cave is a limestone cave located in Harmony, Minnesota. The cave is approximately 200 feet (61 m) deep; features include an underground stream, 60-foot waterfall, fossils, stalactites and stalagmites. The cave is privately owned, with tours available seasonally. The cave was first discovered in 1924, and in 1932, three caving, spelunkers Al Cremer, Leo Tekippe, and Joe Flynn explored the cave and named the site Niagara Cave. Niagara Cave opened as a show cave in June 1934, and was described by geologist J Harlen Bretz in 1938. The Minnesota Geological Survey noted in their 1995 survey, "Niagara Cave contains an excellent example of an underground river, complete with waterfall."

Fillmore County, Minnesota
Fillmore County is a county in the U.S. state of Minnesota. As of the 2020 census, the population was 21,228. Its county seat is Preston. Fillmore County is included in the Rochester metropolitan area. History Fillmore County was created on March 5, 1853. It is named for Millard Fillmore, the 13th president of the United States. Fillmore County was an early destination for Euro-American settlement following the United States' 1851 treaties with the Dakota nations. Norwegian immigrants were particularly numerous. In 1860 Fillmore was Minnesota's most populous county. Geography Fillmore County is on Minnesota's border with Iowa. The Root River drains the county, flowing eastward. The North Branch and the Middle Branch combine east of Shady Creek, while the South Branch meets their combined flow at Preston. Bear Creek drains the lower part of the county, discharging into the Root in the eastern part of the county. Willow Creek also drains a portion of the lower county, disch ...

Stalagmites
A stalagmite (, ; ; ) 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. 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 carbonate and other minerals, which is precipitated from mineralized water solutions. Limestone is the chief form of calcium carbonate rock, which is dissolved by water that contains carbon dioxide, forming a calcium bicarbonate solution in caverns. The partial pressure of carbon dioxide in the water must be greater than ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tourist Attractions In Minnesota
Tourism is travel for pleasure, and the commercial activity of providing and supporting such travel. UN Tourism defines tourism more generally, in terms which go "beyond the common perception of tourism as being limited to holiday activity only", as people "travelling to and staying in places outside their usual environment for not more than one consecutive year for leisure and not less than 24 hours, business and other purposes". Tourism can be domestic (within the traveller's own country) or international. International tourism has both incoming and outgoing implications on a country's balance of payments. Between the second half of 2008 and the end of 2009, tourism numbers declined due to a severe economic slowdown (see Great Recession) and the outbreak of the 2009 H1N1 influenza virus. These numbers, however, recovered until the COVID-19 pandemic put an abrupt end to the growth. The United Nations World Tourism Organization has estimated that global international tourist a ...

Limestone Caves
Limestone is a type of carbonate sedimentary rock which is the main source of the material lime. It is composed mostly of the minerals calcite and aragonite, which are different crystal forms of calcium carbonate . Limestone forms when these minerals precipitate out of water containing dissolved calcium. This can take place through both biological and nonbiological processes, though biological processes, such as the accumulation of corals and shells in the sea, have likely been more important for the last 540 million years. Limestone often contains fossils which provide scientists with information on ancient environments and on the evolution of life. About 20% to 25% of sedimentary rock is carbonate rock, and most of this is limestone. The remaining carbonate rock is mostly dolomite, a closely related rock, which contains a high percentage of the mineral dolomite, . ''Magnesian limestone'' is an obsolete and poorly-defined term used variously for dolomite, for limeston ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
List Of Waterfalls
This list of notable waterfalls of the world is sorted by continent, then country, then province, state or territory. A waterfall is included if it is at least tall and has an existing Wikipedia article, or it is considered historically significant based on multiple reliable references. There is no standard way to measure the height or width of a waterfall. No ranking of waterfalls should be assumed because of the heights or widths provided in the list. Many numbers are estimated and measurements may be imprecise.

J Harlen Bretz
J Harlen Bretz (2 September 1882 – 3 February 1981) was an American geologist, best known for his research that led to the acceptance of the Missoula Floods and for his work on caves. Early life and education Bretz was born on 2 September 1882, in the small town of Saranac in Ionia County, Michigan. He was the first of Oliver Joseph Bretz and Rhoda Maria Howlett's five children. His father was a farmer, and proud descendant of early German settler in Ohio, John Bretz. The county's birth registry recorded his name as "Harlan J Bretz" at birth, but he was listed as "Harland J Bretz" on the 1900 United States Census. When he entered college in 1901, he applied as "J Harlen Bretz". At around the time he completed his graduate studies in 1913, he stopped using a point after the initial at "J". According to his two children, his given name was actually "Harley". Bretz's daughter Rhoda Bretz Riley went on to explain that "he invented the Harlen thing, just as he had invented the ...

Show Cave
A show cave—also called tourist cave, public cave, and, in the United States, commercial cave—is a cave which has been made accessible to the public for guided visits. Definition A show cave is a cave that has been made accessible to the public for guided visits, where a cave is defined as a natural occurring void beneath the surface of the earth, per the International Show Caves Association. A show cave may be managed by a government or commercial organization and made accessible to the general public, usually for an entrance fee. Unlike wild caves, they may possess regular opening hours, guided group tours, constructed trails and stairs, color artificial illumination and other lighting, musical/video/laser shows and concerts, elevators, small trains, and boats if they contain underground water features. Some caves (mainly in Asia) open to the public have temples, monasteries and religious statues or monuments. Some caves are visited by millions of tourists annually ...

Caving
Caving, also known as spelunking (United States and Canada) and potholing (United Kingdom and Ireland), is the recreational pastime of exploring wild cave systems (as distinguished from show caves). In contrast, speleology is the scientific study of caves and the cave environment.Caving in New Zealand (from Te Ara: The Encyclopedia of New Zealand, Accessed 2012-11.) The challenges involved in caving vary according to the cave being visited; in addition to the total absence of light beyond the entrance, negotiating pitches, squeezes, and water hazards can be difficult.

Stalactites
A stalactite (, ; , ) 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. Formation and type Limestone stalactites The most common stalactites are speleothems, which occur in limestone caves. They form through deposition of calcium carbonate and other minerals, which is precipitated from mineralized water solutions.
