Schrofen
Schrofen, a German mountaineering term, is steep terrain, strewn with rocks and rock outcrops, that is laborious to cross, but whose rock ledges (''schrofen'') offer many good steps and hand holds. It is usually rocky terrain on which grass has established itself, but it can also refer to purely rocky slopes. ''Schrofen'' are found especially where the rock has broken off against its angle of dip. ''Schrofen'' differs from trackless terrain in that hands are needed in order to negotiate it. Often there are route markings that only indicate a rough direction. ("How to negotiate ''schrofen'' terrain safely") at www.alpin.de. Accessed on 31 Dec 2010 ''Schrofen'' terrain requires at least |
Angle Of Dip
In geology, strike and dip is a measurement convention used to describe the plane orientation or attitude of a planar geologic feature. A feature's strike is the azimuth of an imagined horizontal line across the plane, and its dip is the angle of inclination (or depression angle) measured downward from horizontal. They are used together to measure and document a structure's characteristics for study or for use on a geological map. A feature's orientation can also be represented by dip and dip direction, using the azimuth of the dip rather than the strike value. Linear features are similarly measured with trend and plunge, where "trend" is analogous to dip direction and "plunge" is the dip angle. Strike and dip are measured using a compass and a clinometer. A compass is used to measure the feature's strike by holding the compass horizontally against the feature. A clinometer measures the feature's dip by recording the inclination perpendicular to the strike. These can be done ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sure-footedness
Sure-footedness is the ability, especially when hiking or mountain climbing, to navigate difficult or rough terrain safely. Such situations place demands on a person's coordination and reserves of strength as well as requiring sufficient appreciation of the terrain. A person who is sure-footed is thus unlikely to slip or stumble, and will have a good head for heights when required. On many hiking trails and mountain tours, sure-footedness is assumed to be a prerequisite without ever being defined. The term is frequently used in the literature presumably to ensure that the reader is made sufficiently aware that, under certain circumstances, one false step may lead to serious consequences. Required attributes Although there is no standard definition of sure-footedness, [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Climbing Grade
Many climbing routes have grades for the technical difficulty, and in some cases for the risks, of the route. The first ascensionist can suggest a grade but it will be amended for the ''consensus view'' of subsequent ascents. While many countries with a tradition of climbing developed their own grading systems, a small number of grading systems have become internationally dominant for each type of climbing, and which has led to the standardization of grading worldwide. Over the years, grades have consistently risen in all forms of climbing, helped by improvements in climbing technique and equipment. In free climbing (i.e. climbing rock routes with no aid), the most popular grading systems are the French numerical or sport system (e.g. f7c+), the American YDS system (e.g. 5.13a), and latterly the UIAA scale (e.g. IX+). These systems grade technical difficulty being the main focus of the lower-risk activity of sport climbing. The American system adds an R/X suffix to tra ...

Northern Limestone Alps
The Northern Limestone Alps (), also called the Northern Calcareous Alps, are the ranges of the Eastern Alps north of the Central Eastern Alps located in Austria and the adjacent Bavarian lands of southeastern Germany. The distinction from the latter group, where the higher peaks are located, is based on differences in geological composition. Geography If viewed on a west–east axis, the Northern Limestone Alps extend from the Rhine valley and the Bregenz Forest in Vorarlberg, Austria in the west extending along the border between the German federal-state of Bavaria and Austrian Tyrol, through Salzburg, Upper Austria, Styria and Lower Austria and finally ending at the Wienerwald at the city-limits of Vienna in the east. The highest peaks in the Northern Limestone Alps are the Parseierspitze () in the Lechtal Alps,Reynolds, Kev (2010). ''Walking in the Alps'', Cicerone, . and the Hoher Dachstein (). Other notable peaks in this range include the Zugspitze, (), located on t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Geographical Terminology In Mountaineering
Geography (from Ancient Greek ; combining 'Earth' and 'write', literally 'Earth writing') is the study of the lands, features, inhabitants, and phenomena of Earth. Geography is an all-encompassing discipline that seeks an understanding of Earth and its human and natural complexities—not merely where objects are, but also how they have changed and come to be. While geography is specific to Earth, many concepts can be applied more broadly to other celestial bodies in the field of planetary science. Geography has been called "a bridge between natural science and social science disciplines." Origins of many of the concepts in geography can be traced to Greek Eratosthenes of Cyrene, who may have coined the term "geographia" (). The first recorded use of the word γεωγραφία was as the title of a book by Greek scholar Claudius Ptolemy (100 – 170 AD). This work created the so-called "Ptolemaic tradition" of geography, which included "Ptolemaic cartographic theory." ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Geomorphology
Geomorphology () is the scientific study of the origin and evolution of topographic and bathymetric features generated by physical, chemical or biological processes operating at or near Earth's surface. Geomorphologists seek to understand why landscapes look the way they do, to understand landform and terrain history and dynamics and to predict changes through a combination of field observations, physical experiments and numerical modeling. Geomorphologists work within disciplines such as physical geography, geology, geodesy, engineering geology, archaeology, climatology, and geotechnical engineering. This broad base of interests contributes to many research styles and interests within the field. Overview Earth's surface is modified by a combination of surface processes that shape landscapes, and geologic processes that cause tectonic uplift and subsidence, and shape the coastal geography. Surface processes comprise the action of water, wind, ice, wildfire, and lif ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
