Giant's Kettle
A giant's kettle, also known as either a giant's cauldron, moulin pothole, or glacial pothole, is a typically large and cylindrical Pothole (landform), pothole drilling, drilled in solid rock (geology), rock underlying a glacier either by water descending down a deep Moulin (geomorphology), moulin or by gravel rotating in the bed of Subglacial stream, subglacial meltwater stream.Neuendorf, K.K.E., J.P. Mehl, Jr., and J.A. Jackson, eds. (2005) ''Glossary of Geology'' (5th ed.). Alexandria, Virginia, American Geological Institute. 779 pp. The interiors of potholes tend to be smooth and regular, unlike a plunge pool. Formation Giant's kettles are formed while a bedrock surface is covered by a glacier. Water, produced by the thawing of the ice and snow, forms streams on the surface of the glacier, which, having gathered into their courses a certain amount of Moraine, morainic debris, finally flow down a crevasse as a swirling waterfall, cascade or Moulin (geomorphology), moulin. ...

Glacial Pothole WI
A glacier (; or ) is a persistent body of dense ice, a form of rock, that is constantly moving downhill under its own weight. A glacier forms where the accumulation of snow exceeds its Ablation#Glaciology, ablation over many years, often centuries. It acquires distinguishing features, such as crevasses and seracs, as it slowly flows and deforms under stresses induced by its weight. As it moves, it abrades rock and debris from its substrate to create landforms such as cirques, moraines, or fjords. Although a glacier may flow into a body of water, it forms only on land“Glacier, N., Pronunciation.” Oxford English Dictionary, Oxford University Press, Oxford UP, June 2024, https://doi.org/10.1093/OED/7553486115. Accessed 25 Jan. 2025. and is distinct from the much thinner sea ice and lake ice that form on the surface of bodies of water. On Earth, 99% of glacial ice is contained within vast ice sheets (also known as "continental glaciers") in the polar regions, but glaciers may ...

Plumbing
Plumbing is any system that conveys fluids for a wide range of applications. Plumbing uses piping, pipes, valves, piping and plumbing fitting, plumbing fixtures, Storage tank, tanks, and other apparatuses to convey fluids. HVAC, Heating and cooling (HVAC), Sewerage, waste removal, and Drinking water, potable water delivery are among the most common uses for plumbing, but it is not limited to these applications. The word derives from the Latin for lead, ''plumbum'', as the first effective pipes used in the Sanitation in ancient Rome, Roman era were lead pipes. In the developed world, plumbing infrastructure is critical to public health and sanitation. Boilermakers and pipefitters are not plumbers although they work with piping as part of their trade and their work can include some plumbing. History Plumbing originated during ancient civilizations, as they developed public baths and needed to provide drinking water, potable water and sewerage, wastewater removal for large ...

Blekinge
Blekinge () is one of the traditional Swedish provinces (), situated in the southern coast of the geographic region of Götaland, in southern Sweden. It borders Småland, Scania and the Baltic Sea. It is the country's second-smallest province by area (only Öland is smaller), and the smallest province located on the mainland. The name "Blekinge" comes from the dialectal adjective , which corresponds to the nautical term for "dead calm". Administration The historical provinces of Sweden serve no administrative function. However, Blekinge is the only province, besides Gotland, which covers exactly the same area as the administrative county, which is Blekinge County. Heraldry Blekinge was granted its current arms in 1660 at the time of the funeral of King Charles X Gustav of Sweden (1622–1660) based on a seal from the 15th century. Symbolically the three crowns from the Coat of arms of Sweden had been placed on the trunk of the tree to mark the change in status of t ...

Moss Island
Moss Island is an island in Little Falls, New York, located between the Mohawk River and the New York State Barge Canal. It is composed of an igneous intrusion of syenite, and became an island when canal locks were built so boats could avoid the falls. It is known for its large deep potholes as well as being popular with local rock climbers. It was declared a National Natural Landmark in 1976. Efforts by the local community to turn Moss Island into a New York State Park were begun in 2008. Description Moss Island is long and wide. It is bordered by the Mohawk River on the north and the New York State Barge Canal to the south. It is covered in dwarf oak trees. Glacial striations are visible in some places. The southern cliff at its highest point is tall. The cliff has an adjacent road and spans about three-quarters of the island. Geology The cliffs of Moss Island are composed of metasyenite. Syenite is an igneous rock, similar to granite, composed of crystals of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hiisi
Hiisi (; plural ''hiidet'' ) is a term in Finnic mythologies, originally denoting sacred localities and later on various types of mythological entities. In later, Christian-influenced folklore, they are depicted as demonic or trickster-like entities, often the autochthonous, pagan inhabitants of the land, similar in this respect to mythological giants. They are found near salient promontories, ominous crevasses, large boulders, potholes, woods, hills, and other outstanding geographical features or rough terrain. Origin and etymology Hiisi was originally a spirit of hill forests . In Estonian '' hiis'' (or ''his'') means a sacred grove in trees, usually on elevated ground. In the spells ("magic songs") of the Finns the term Hiisi is often used in association with a hill or mountain, as a personage he also associated with the hills and mountains, such as the owner or ruler of the same. His name is also commonly associated with forests, and some forest animals. More recent spec ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Outburst Flood
In geomorphology, an outburst flood—a type of megaflood—is a high-magnitude, low-frequency catastrophic flood involving the sudden release of a large quantity of water. During the last deglaciation, numerous glacial lake outburst floods were caused by the collapse of either ice sheets or glaciers that formed the dams of proglacial lakes. Examples of older outburst floods are known from the geological past of the Earth and inferred from geomorphological evidence on Mars. Landslides, lahars, and volcanic dams can also block rivers and create lakes, which trigger such floods when the rock or earthen barrier collapses or is eroded. Lakes also form behind glacial moraines or ice dams, which can collapse and create outburst floods. Definition and classification Megafloods are paleofloods (past floods) that involved rates of water flow larger than those in the historical record. They are studied through the sedimentary deposits and the erosional and constructional landforms th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Channeled Scablands
The Channeled Scablands are a relatively barren and soil-free region of interconnected relict and dry flood channels, coulees and cataracts eroded into Palouse loess and the typically flat-lying basalt flows that remain after cataclysmic floods within the southeastern part of Washington state.Neuendorf, K.K.E., J.P. Mehl, Jr., and J.A. Jackson, eds. (2005) ''Glossary of Geology'' (5th ed.). Alexandria, Virginia, American Geological Institute. 779 pp. The Channeled Scablands were scoured by more than 40 cataclysmic floods during the Last Glacial Maximum and innumerable older cataclysmic floods over the last two million years. These floods were periodically unleashed whenever a large glacial lake broke through its ice dam and swept across eastern Washington and down the Columbia River Plateau during the Pleistocene epoch. The last of the cataclysmic floods occurred between 18,200 and 14,000 years ago.Balbas, A.M., Barth, A.M., Clark, P.U., Clark, J., Caffee, M., O'Connor, J., B ...
