Pinnacle (geology)
A pinnacle, tower, spire, needle or natural tower (, ''Felsturm'' or ''Felszinne'') in geology is an individual column of rock, isolated from other rocks or groups of rocks, in the shape of a vertical shaft or spire. is a natural geomorphological shape and a structural denudation shape of the relief. It is about an isolated, tall and often also slender column or prism, reminiscent of a tower in its shape. A specific type of rock tower is the rock needle. Formation The rock tower was created as a result of mechanical erosion, namely the gradual breakdown and destruction of a flat plateau or a rocky mountain ridge. Its shape is the result of mechanical weathering and the attitude of the rock, or the subsidence of the slope. On the sea coast, rock towers are created by abrasion and isolation of the more resistant parts of the worn and abraded coast (cliff). Distribution Rock towers are found in various parts of the world. They are found on the edges of high mountains a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

The Pinnacles (Western Australia)
The Pinnacles are limestone formations within Nambung National Park, near the town of Cervantes, Western Australia. Features The area contains thousands of weathered limestone pillars. Some of the tallest pinnacles reach heights of up to above the yellow sand base. The different types of formations include ones which are much taller than they are wide and resemble columnssuggesting the name of Pinnacleswhile others are only or so in height and width resembling short tombstones. A cross-bedding structure can be observed in many pinnacles where the angle of deposited sand changed suddenly due to changes in prevailing winds during formation of the limestone beds. Pinnacles with tops similar to mushrooms are created when the calcrete capping is harder than the limestone layer below it. The relatively softer lower layers weather and erode at a faster rate than the top layer leaving behind more material at the top of the pinnacle. Formation The raw material for the limestone ...

Cervantes, Western Australia
Cervantes is a town in Western Australia located about north-north-west of the state capital, Perth, in the Shire of Dandaragan local government area. At the 2016 census, Cervantes had a population of 527. The town was named after a ship that was wrecked nearby. The ship, in turn, was named after Miguel de Cervantes, author of ''Don Quixote''. The principal industry in the town is fishing. The Pinnacles are nearby in Nambung National Park which supports a small tourism industry. The saline Lake Thetis, which contains stromatolite Stromatolites ( ) or stromatoliths () are layered Sedimentary rock, sedimentary formation of rocks, formations (microbialite) that are created mainly by Photosynthesis, photosynthetic microorganisms such as cyanobacteria, sulfate-reducing micr ...s, is nearby. An arts festival is held every year in the town, usually on the last weekend of October. Cervantes lies on the shore of the Jurien Bay Marine Park.

Nambung National Park
Nambung National Park is a national park in the Wheatbelt (Western Australia), Wheatbelt region of Western Australia, northwest of the state capital Perth, and south of the small coastal town of Cervantes, Western Australia, Cervantes. The park contains the Pinnacles Desert which is an area with thousands of limestone formations called ''Rock pinnacle, pinnacles''. The park derives its name from an indigenous Australian word possibly meaning crooked or winding. The word was used in 1938 when naming the Nambung River which flows into the park and disappears into a cave system within the limestone. The Yued people are the acknowledged traditional custodians of the land since before the arrival of Europeans. Nambung National Park also contains beaches at Kangaroo Point and Hangover Bay, as well as coastal dunes and flowering plants in low heathland areas. A boardwalk in the northern area of the park at Lake Thetis allows visitors to view thrombolites which, like stromatolites, are ...

Limestone
Limestone is a type of carbonate rock, carbonate sedimentary rock which is the main source of the material Lime (material), lime. It is composed mostly of the minerals calcite and aragonite, which are different Polymorphism (materials science), crystal forms of calcium carbonate . Limestone forms when these minerals Precipitation (chemistry), 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 (rock), dolomite, a closely related rock, which contains a high percentage of the mineral Dolomite (mine ...

Dolomites
The Dolomites ( ), also known as the Dolomite Mountains, Dolomite Alps or Dolomitic Alps, are a mountain range in northeastern Italy. They form part of the Southern Limestone Alps and extend from the River Adige in the west to the Piave Valley ( Pieve di Cadore) in the east. The northern and southern borders are defined by the Puster Valley and the Sugana Valley (). The Dolomites are in the regions of Veneto, Trentino-Alto Adige/Südtirol and Friuli-Venezia Giulia, covering an area shared between the provinces of Belluno, Vicenza, Verona, Trentino, South Tyrol, Udine and Pordenone. Other mountain groups of similar geological structure are spread along the River Piave to the east—; and far away over the Adige River to the west—'' Dolomiti di Brenta'' (Western Dolomites). A smaller group is called (Little Dolomites), between the provinces of Trentino, Verona and Vicenza. The Dolomiti Bellunesi National Park and many other regional parks are in the Dolomites.

Drei Zinnen
The ; ), also called the ; ), are three distinctive battlement-like peaks, in the Sexten Dolomites of northeastern Italy. They are one of the best-known mountain groups in the Alps. The three peaks, from east to west, are: *Cima Piccola / Kleine Zinne ("little peak") *Cima Grande / Große Zinne ("big peak") *Cima Ovest / Westliche Zinne ("western peak"). The peaks are composed of well-layered dolomites of the Dolomia Principale (Hauptdolomit) formation, Carnian to Rhaetian in age, as are many other groups in the Dolomites (e.g., the Tofane, the Pelmo or the Cinque Torri). Until 1919 the peaks formed part of the border between Italy and Austria-Hungary. Now they lie on the border between the Italian provinces of South Tyrol and Belluno and still are a part of the linguistic boundary between German-speaking and Italian-speaking majorities. The Cima Grande has an elevation of . It stands between the Cima Piccola, at , and the Cima Ovest, at . Location and surroundings The ...

Große Bischofsmütze The Große Bischofsmütze (German: "great bishop's mitre") is the highest peak in the Gosaukamm range of the Dachstein Mountains, Austria. Together with the Kleine Bischofsmütze (), the Große Bischofsmütze () forms a distinctive twin-peak, with the two summits separated by the ''Mützenschlucht'' ravine''.'' The mountain is in the state of Salzburg, near the border with Upper Austria, and forms part of the larger Northern Limestone Alps. History The name of the mountain can be attributed to its characteristic shape, that resembles a bishop's mitre ("Bischofsmütze"). The mountain has also been referred to historically as ''Gosauer Stein'' ("Stone of Gosau") due to its location overlooking the town of Gosau. The Große Bischofsmütze was first ascended on June 28, 1879 by Johann Anhäusler and Johann Steiner. Two major rockfalls occurred in 1993 that displaced of rock into the valley below, altering the mountain's visual profile. |
