Kelchstein
The Kelchstein ("Chalice Rock") is a mushroom rock in the Zittau Mountains near Oybin in the German state of Saxony. Geology The Kelchstein consists of a Cretaceous sandstone with very little cementing material. Its unusual mushroom shape has been caused by wind and other erosive processes on sandstone strata of different hardness. Climbing The Kelchstein is one of the best known climbing rocks in the Zittau Mountains. It was first climbed before 1785, when woodcutters fixed a plaque to the summit; the plaque is no longer there. Its development for sports climbing started on 3 September 1911. Dresden climbers ascended the rocks with the aid of a tree at its northwestern corner. The first sports climb without any aids was up the present-day "Old Way" (''Alter Weg'') by Siegfried Schreiber on 26 June 1946. The ''Kelch'' is one of the most difficult summits to climb in the Zittau Mountains. Today there are only five routes, all at climbing grade In rock climbing, mountain ...

Oybin
Oybin ( hsb, Ojbin) is a municipality in the Görlitz district, in Saxony, Germany, located very close to the border of the Czech Republic. Following the defeat of the Protestant armies by the Habsburgs in the Battle of the White Mountain in 1620, many Protestant Czechs found refuge across the border in the hills of Upper Lusatia. It is a "''Kurort''", a resort or spa certified by the state, where people go for rest and recuperation. It is most famous for its mountain of the same name, an exposed natural sandstone dome that towers above the town. The ruins of a medieval monastery lend a wild romantic beauty to it and it was a favorite subject of 19th-century Romantic painters like Caspar David Friedrich. Many bizarrely shaped geological rock formations can be found in the surroundings. The scenic narrow gauge Zittau–Kurort Oybin/Kurort Jonsdorf railway runs from Oybin to Bertsdorf, from there to the neighboring municipality of Jonsdorf and the town of Zittau. Oybin municipa ...

Mushroom Rock
A mushroom rock, also called rock pedestal, or a pedestal rock, is a naturally occurring rock whose shape, as its name implies, resembles a mushroom. The rocks are deformed in a number of different ways: by erosion and weathering, glacial action, or from a sudden disturbance. Mushroom rocks are related to, but different from, ''yardang''. A mushroom rock, rock pedestal, or gour is a typical mushroom-shaped landform that is formed by the action of wind erosion. At an average height of from the base, the material-carrying capacity of the wind is at its maximum, so abrasion (erosion by wind in which transported materials hit an exposed rock surface and polish it or scratch it) is also maximized. In some cases, harder rocks are arranged horizontally over a softer rock, resulting in such erosion. Erosion Usually found in desert areas, these rocks form over thousands of years when wind erosion of an isolated rocky outcrop progresses at a different rate at its bottom than at its top. ...

Zittau Mountains
The Zittau Mountains (german: Zittauer Gebirge, cs, Žitavské hory), formerly also called the Lusatian Ridge (''Lausitzer Kamm''), refer to the German part of the Lusatian Mountains that straddle the Saxon- Bohemian border in the extreme southeast of the German state of Saxony. Geography Location The Zittau Mountains lie in the extreme south of the district of Görlitz in Saxony. A few kilometres north of the range lie a number of settlements; from west to east they are Großschönau, Hainewalde, Olbersdorf, Bertsdorf-Hörnitz and Zittau. In the mountains themselves are, again from west to east, the settlements of Waltersdorf, Oybin, Jonsdorf and Lückendorf . The highlands are drained by streams that flow roughly north into the Mandau, a western tributary of the Lusatian Neisse. Mountains Among the highest mountains in the range are the following (in order of height in m above NN: [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Saxony
Saxony (german: Sachsen ; Upper Saxon: ''Saggsn''; hsb, Sakska), officially the Free State of Saxony (german: Freistaat Sachsen, links=no ; Upper Saxon: ''Freischdaad Saggsn''; hsb, Swobodny stat Sakska, links=no), is a landlocked state of Germany, bordering the states of Brandenburg, Saxony-Anhalt, Thuringia, Bavaria, as well as the countries of Poland and the Czech Republic. Its capital is Dresden, and its largest city is Leipzig. Saxony is the tenth largest of Germany's sixteen states, with an area of , and the sixth most populous, with more than 4 million inhabitants. The term Saxony has been in use for more than a millennium. It was used for the medieval Duchy of Saxony, the Electorate of Saxony of the Holy Roman Empire, the Kingdom of Saxony, and twice for a republic. The first Free State of Saxony was established in 1918 as a constituent state of the Weimar Republic. After World War II, it was under Soviet occupation before it became part of the communist East Ger ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cretaceous
The Cretaceous ( ) is a geological period that lasted from about 145 to 66 million years ago (Mya). It is the third and final period of the Mesozoic Era, as well as the longest. At around 79 million years, it is the longest geological period of the entire Phanerozoic. The name is derived from the Latin ''creta'', "chalk", which is abundant in the latter half of the period. It is usually abbreviated K, for its German translation ''Kreide''. The Cretaceous was a period with a relatively warm climate, resulting in high eustatic sea levels that created numerous shallow inland seas. These oceans and seas were populated with now- extinct marine reptiles, ammonites, and rudists, while dinosaurs continued to dominate on land. The world was ice free, and forests extended to the poles. During this time, new groups of mammals and birds appeared. During the Early Cretaceous, flowering plants appeared and began to rapidly diversify, becoming the dominant group of plants across the Earth b ...

Cementing Material
The matrix or groundmass of a rock is the finer-grained mass of material in which larger grains, crystals, or clasts are embedded. The matrix of an igneous rock consists of finer-grained, often microscopic, crystals in which larger crystals, called phenocrysts, are embedded. This porphyritic texture is indicative of multi-stage cooling of magma. For example, porphyritic andesite will have large phenocrysts of plagioclase in a fine-grained matrix. Also in South Africa, diamonds are often mined from a matrix of weathered clay-like rock (kimberlite) called "yellow ground". The matrix of sedimentary rocks is finer-grained sedimentary material, such as clay or silt, in which larger grains or clasts are embedded. It is also used to describe the rock material in which a fossil is embedded. Cementation All sediments are at first in an incoherent condition (e.g. sands, clays and gravels, beds of shells), and they may remain in this state for an indefinite period. Millions of years hav ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wind Erosion
Aeolian processes, also spelled eolian, pertain to wind activity in the study of geology and weather and specifically to the wind's ability to shape the surface of the Earth (or other planets). Winds may erode, transport, and deposit materials and are effective agents in regions with sparse vegetation, a lack of soil moisture and a large supply of unconsolidated sediments. Although water is a much more powerful eroding force than wind, aeolian processes are important in arid environments such as deserts. The term is derived from the name of the Greek god Aeolus, the keeper of the winds. Definition and setting ''Aeolian processes'' are those processes of erosion, transport, and deposition of sediments that are caused by wind at or near the surface of the earth. Sediment deposits produced by the action of wind and the sedimentary structures characteristic of these deposits are also described as ''aeolian''. Aeolian processes are most important in areas where there is little ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Erosion (geology)
Erosion is the action of surface processes (such as water flow or wind) that removes soil, rock, or dissolved material from one location on the Earth's crust, and then transports it to another location where it is deposited. Erosion is distinct from weathering which involves no movement. Removal of rock or soil as clastic sediment is referred to as ''physical'' or ''mechanical'' erosion; this contrasts with ''chemical'' erosion, where soil or rock material is removed from an area by dissolution. Eroded sediment or solutes may be transported just a few millimetres, or for thousands of kilometres. Agents of erosion include rainfall; bedrock wear in rivers; coastal erosion by the sea and waves; glacial plucking, abrasion, and scour; areal flooding; wind abrasion; groundwater processes; and mass movement processes in steep landscapes like landslides and debris flows. The rates at which such processes act control how fast a surface is eroded. Typically, physical erosion proceed ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Climbing Grade
In rock climbing, mountaineering, and other climbing disciplines, climbers give a grade to a climbing route or boulder problem, intended to describe concisely the difficulty and danger of climbing it. Different types of climbing (such as sport climbing, bouldering or ice climbing) each have their own grading systems, and many nationalities developed their own, distinctive grading systems. There are a number of factors that contribute to the difficulty of a climb, including the technical difficulty of the moves, the strength, stamina and level of commitment required, and the difficulty of protecting the climber. Different grading systems consider these factors in different ways, so no two grading systems have an exact one-to-one correspondence. Climbing grades are inherently subjective.Reynolds Sagar, Heather, 2007, ''Climbing your best: training to maximize your performance'', Stackpole Books, UK, 9.

Climbing Areas Of Germany
Climbing is the activity of using one's hands, feet, or any other part of the body to ascend a steep topographical object that can range from the world's tallest mountains (e.g. the eight thousanders), to small boulders. Climbing is done for locomotion, sporting recreation, and for competition, and is also done in trades that rely on ascension; such as emergency rescue and military operations. Climbing is done indoors and outdoors and on natural (e.g. rock and ice) and artificial surfaces. Professional mountain guides or rock climbing guides (e.g. the UIAGM), were a significant element in developing the popularity of the sport in the natural environment, and remain so today. Since the 1980s, the development of competition climbing and the availability of artificial climbing walls have dramatically increased the popularity of rock climbing as a sport and led to the emergence of professional rock climbers, such as Wolfgang Güllich, Chris Sharma, Lynn Hill and Catherine ...
