Top Roping
Top rope climbing (or top roping) is a style in climbing in which the climber is securely attached to a rope which then passes up, through an anchor system at the top of the climb, and down to a belayer at the foot of the climb. The belayer takes in slack rope throughout the climb, so that if at any point the climber were to lose their hold, they would not fall more than a short distance. Description Top-roping is often done on routes that cannot be lead climbed for one reason or another. Most top-rope anchors can be reached through non-technical means, such as by hiking or scrambling to the top of the cliff. It is the most common style used at indoor climbing walls and is also used in situations where other methods would be unsafe or environmentally damaging. For example, in Kent and Sussex in south-east England, the sandstone rock is soft and prone to erosion, so placing protection into the rock would be both damaging and unreliable. There, top-roping from permanent anchors a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Sandstone
Sandstone is a clastic sedimentary rock composed mainly of sand-sized (0.0625 to 2 mm) silicate grains. Sandstones comprise about 20–25% of all sedimentary rocks. Most sandstone is composed of quartz or feldspar (both silicates) because they are the most resistant minerals to weathering processes at the Earth's surface. Like uncemented sand, sandstone may be any color due to impurities within the minerals, but the most common colors are tan, brown, yellow, red, grey, pink, white, and black. Since sandstone beds often form highly visible cliffs and other topographic features, certain colors of sandstone have been strongly identified with certain regions. Rock formations that are primarily composed of sandstone usually allow the percolation of water and other fluids and are porous enough to store large quantities, making them valuable aquifers and petroleum reservoirs. Quartz-bearing sandstone can be changed into quartzite through metamorphism, usually related to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Types Of Climbing
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 bouldering, 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 ...

Black Forest
The Black Forest (german: Schwarzwald ) is a large forested mountain range in the state of Baden-Württemberg in southwest Germany, bounded by the Rhine Valley to the west and south and close to the borders with France and Switzerland. It is the source of the Danube and Neckar rivers. Its highest peak is the Feldberg with an elevation of above sea level. Roughly oblong in shape, with a length of and breadth of up to , it has an area of about 6,009 km2 (2,320 sq mi). Historically, the area was known for forestry and the mining of ore deposits, but tourism has now become the primary industry, accounting for around 300,000 jobs. There are several ruined military fortifications dating back to the 17th century. History In ancient times, the Black Forest was known as , after the Celtic deity, Abnoba. In Roman times (Late antiquity), it was given the name ("Marcynian Forest", from the Germanic word ''marka'' = "border"). The Black Forest probably represented the bo ...

Protection (climbing)
Climbing protection is any of a variety of devices employed to reduce risk and protect others while climbing rock and ice. It includes such items as nylon webbing and metal nuts, cams, bolts, and pitons. Different forms of climbing draw on varying forms of protection and the systems that are created from its elements. Types of climbing There are a number of ways to "protect" a climb, varying according to the type of climbing: Lead climbing A lead climber places protection (temporary or permanent anchors) in the rock, snow, or ice establishing a climbing route. The rope is clipped through carabiners (often joined by a short length of webbing into a pair known as a quickdraw) which are in turn connected to the protection. The belayer pays out rope during the ascent, and manually arrests the climber's fall by locking the rope, typically with some form of belay device. Aid climbing Aid climbing involves standing on or pulling oneself up via devices attached to fixed or p ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Traditional Climbing
Traditional climbing (or Trad climbing) is a style of rock climbing in which the climber places all the necessary protection gear required to arrest any falls as they are climbing, and then removes it when the pitch is complete (often done by the second/follow-on climber). Traditional bolted aid climbing means the bolts were placed while on lead and/or with hand drills (the bolts tend to be much farther apart than for sport climbs). Traditional climbing carries a higher level of risk than bolted sport climbing, as the climber may not have placed the safety equipment correctly while trying to ascend the route; for some of the world's hardest climbs (e.g. '' Realization/Biographie''), there may not be sufficient cracks or features in the rock that can accept protection gear, and the climb can only be safely attempted by bolting as a sport climb. Overview Characterizing climbing as ''traditional'' distinguishes it from bolted climbing—either trad bolted or sport climbing ...

Carabiner
A carabiner or karabiner () is a specialized type of shackle, a metal loop with a spring-loaded gate used to quickly and reversibly connect components, most notably in safety-critical systems. The word is a shortened form of ''Karabinerhaken'' (or also short ''Karabiner''), a German phrase for a "spring hook" used by a carbine rifleman, or carabinier, to attach his carabin to a belt or bandolier. Use Carabiners are widely used in rope-intensive activities such as climbing, fall arrest systems, arboriculture, caving, sailing, hot air ballooning, rope rescue, construction, industrial rope work, window cleaning, whitewater rescue, and acrobatics. They are predominantly made from both steel and aluminium. Those used in sports tend to be of a lighter weight than those used in commercial applications and rope rescue. Often referred to as carabiner-style or as mini-biners, carabiner keyrings and other light-use clips of similar style and design have also become popular. Most ar ...

Dynamic Rope
A dynamic rope is a specially constructed, somewhat elastic rope used primarily in rock climbing, ice climbing, and mountaineering. This elasticity, or stretch, is the property that makes the rope dynamic—in contrast to a static rope that has only slight elongation under load. Greater elasticity allows a dynamic rope to more slowly absorb the energy of a sudden load, such from arresting a climber's fall, by reducing the peak force on the rope and thus the probability of the rope's catastrophic failure. A kernmantle rope is the most common type of dynamic rope now used. Since 1945, nylon has, because of its superior durability and strength, replaced all natural materials in climbing rope. Rope types Dynamic climbing ropes are classified into three categories: Single ropes, twin ropes, and half ropes (also referred to as 'double ropes'). *Single ropes are designed to be used alone, and are by far the most common, and used for top-roping, sport climbing, and trad climbing. *T ...

Static Rope
A static rope is a low-elongation rope that is designed to stretch minimally when placed under load, typically less than 5%. In contrast, a dynamic rope is designed to stretch up to 40%. Static ropes have a wide variety of uses, for instance in fire rescue operations and caving. Static ropes have some applications in climbing, such as hauling gear, though lead climbing is always done with a dynamic rope, since a fall on a static rope is stopped too quickly and may lead to serious injury. Abseiling, however, is best done with a static rope or with a dynamic rope with low elasticity. See also *Kernmantle rope Kernmantle rope () is rope constructed with its interior core protected by a woven exterior sheath designed to optimize strength, durability, and flexibility. The core fibers provide the tensile strength of the rope, while the sheath protects the ... References * Climbing equipment Ropes {{Climbing-stub ...

Solo Climbing
Solo climbing, or soloing, is a style of climbing in which the climber climbs alone, without the assistance of a belayer. It is not to be confused with bouldering, a short ascent which by definition is done without the assistance of ropes, harness, or climbing partner. Forms of solo climbing include: * Roped solo climbing is climbing alone with a rope backup in case of fall. Roped soloing is especially useful in rescue situations. There are two ways to rope solo: ** Lead solo, in which the climber uses a self-locking device which is used to arrest a fall. One end of the rope may be anchored below the climber with the coils of rope in a bag on the climber's back, or for single-pitch climbs the device may be secured at ground level, and the climber tied into the end of the rope. ** Top rope solo, in which the climber uses a self-locking device and climbs as if top roping. If weight is put on the rope during the climb, it is a form of aided climbing. * Free solo climbing (know ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

England
England is a country that is part of the United Kingdom. It shares land borders with Wales to its west and Scotland to its north. The Irish Sea lies northwest and the Celtic Sea to the southwest. It is separated from continental Europe by the North Sea to the east and the English Channel to the south. The country covers five-eighths of the island of Great Britain, which lies in the North Atlantic, and includes over 100 smaller islands, such as the Isles of Scilly and the Isle of Wight. The area now called England was first inhabited by modern humans during the Upper Paleolithic period, but takes its name from the Angles, a Germanic tribe deriving its name from the Anglia peninsula, who settled during the 5th and 6th centuries. England became a unified state in the 10th century and has had a significant cultural and legal impact on the wider world since the Age of Discovery, which began during the 15th century.
