Henry Barber (climber)
Henry Barber (born 1953 in Boston, Massachusetts) is an American rock climber and ice climber who rose to prominence in the 1970s. Known by the nickname "Hot Henry", Barber was an advocate of clean climbing, a prolific first ascenscionist and free soloist. He was one of the first American rock climbers to travel widely to climb in different countries, and was one of the first "professional" American rock climbers, supporting himself as a sales representative for outdoor equipment companies including Chouinard Equipment and Patagonia, and by giving lectures and slide shows. He was an integral member of the "Front Four" quartet of the 1970s: "Hot Henry", John Stannard, Steve Wunsch, and John Bragg. Initial climbs At age 17, Barber started climbing with the Boston chapter of the Appalachian Mountain Club. Although initially not athletically gifted, he became obsessed with the sport, and persevered, climbing as much as possible. By his own account, Henry climbed approximately 27 ...

Nut (climbing)
In rock climbing, a nut (or ''chock'' or ''chockstone'' or wire for the smallest versions) is a metal wedge threaded on a wire that climbers use for protection by wedging it into a crack in the rock. Quickdraws are clipped to the nut wire by the ascending climber and the rope threads through the quickdraw. Nuts come in a variety of sizes and styles, and several different brands are made by competing manufacturers. Most nuts are made of aluminum. Larger nuts may be threaded on Dyneema cord instead of wire, but this has become unusual. The very smallest nuts are known as ''micronuts'' and may be made of brass or other metal, and typically have their wires soldered into them, instead of looped through drilled holes. They are mostly used in aid climbing, and their value as protection, arresting a climber's fall, is marginal because of both their low breaking strength and their tiny surface area (the HB 0 measures about 4 x 7 x 2.5 mm) in contact with the rock, though this can be o ...

Nylon
Nylon is a family of synthetic polymers characterised by amide linkages, typically connecting aliphatic or Polyamide#Classification, semi-aromatic groups. Nylons are generally brownish in color and can possess a soft texture, with some varieties exhibiting a silk-like appearance. As Thermoplastic, thermoplastics, nylons can be melt-processed into fibres, Thin film, films, and diverse shapes. The properties of nylons are often modified by blending with a variety of additives. Numerous types of nylon are available. One family, designated nylon-XY, is derived from diamines and dicarboxylic acids of carbon chain lengths X and Y, respectively. An important example is nylon-6,6 (). Another family, designated nylon-Z, is derived from amino acid, aminocarboxylic acids with carbon chain length Z. An example is nylon-[6]. Nylon polymers have extensive commercial applications, including uses in textiles and fibres (such as apparel, flooring and rubber reinforcement), molded components fo ...

Protection (climbing)
Rock-climbing equipment varies with the specific type of climbing that is undertaken. Bouldering needs the least equipment outside of climbing shoes, climbing chalk and optional crash pads. Sport climbing adds ropes, harnesses, belay devices, and quickdraws to clip into pre-drilled bolts. Traditional climbing adds the need to carry a "rack" of temporary passive and active protection devices. Multi-pitch climbing, and the related big wall climbing, adds devices to assist in ascending and descending fixed ropes. Finally, aid climbing uses unique equipment to give mechanical assistance to the climber in their upward movement (e.g. aiders). Advances in equipment are a key part of the rock climbing history, starting with the climbing rope. Modern devices enable climbers to perform tasks previously done manually, with greater control – in all conditions – and with less effort. Examples of replacements include the harness (replaced tying the rope around the waist) ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sandstone
Sandstone is a Clastic rock#Sedimentary clastic rocks, clastic sedimentary rock composed mainly of grain size, sand-sized (0.0625 to 2 mm) silicate mineral, silicate grains, Cementation (geology), cemented together by another mineral. Sandstones comprise about 20–25% of all sedimentary rocks. Most sandstone is composed of quartz or feldspar, because they are the most resistant minerals to the weathering processes at the Earth's surface. Like uncemented sand, sandstone may be imparted any color by impurities within the minerals, but the most common colors are tan, brown, yellow, red, grey, pink, white, and black. Because sandstone beds can form highly visible cliffs and other topography, topographic features, certain colors of sandstone have become strongly identified with certain regions, such as the red rock deserts of Arches National Park and other areas of the Southwestern United States, American Southwest. Rock formations composed of sandstone usually allow the p ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
East Germany
East Germany, officially known as the German Democratic Republic (GDR), was a country in Central Europe from Foundation of East Germany, its formation on 7 October 1949 until German reunification, its reunification with West Germany (FRG) on 3 October 1990. Until 1989, it was generally viewed as a communist state and described itself as a Socialist state, socialist "workers' and peasants' state". The Economy of East Germany, economy of the country was Central planning, centrally planned and government-owned corporation, state-owned. Although the GDR had to pay substantial war reparations to the Soviets, its economy became the most successful in the Eastern Bloc. Before its establishment, the country's territory was administered and occupied by Soviet forces following the Berlin Declaration (1945), Berlin Declaration abolishing German sovereignty in World War II.

Fritz Wiessner
Fritz Wiessner (February 26, 1900 – July 3, 1988) was a German American pioneer of free climbing. Born in Dresden, Germany, he immigrated to New York City in 1929 and became a U.S. citizen in 1935. In 1939, he made one of the earliest attempts to conquer K2, one of the most difficult mountains in the world to climb. Early days Wiessner started climbing with his father in the Austrian Alps before World War I. At the age of 12, he climbed the Zugspitze, the highest peak in Germany. In the 1920s, he established hard climbing routes in Saxony and the Dolomites that have a present-day difficulty rating of up to Grade (climbing), 5.11. That was at a time when the hardest free climbing grade in the United States was Grade (climbing), 5.7. At the age of 25, he made a first ascent of the ''Fleischbank (Kaiser), Fleischbank'' in state of Tyrol, Tyrol, which was proclaimed the hardest rock climb done at that time. Wiessner was tall, slope-shouldered and stocky. He had a wide and fri ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Steck-Salathé Route (Sentinel Rock)
The Steck-Salathé Route is a big wall traditional climbing route up Sentinel Rock. History The route was first climbed, in extremely hot weather with minimal water, from June 30 - July 4, 1950, by Allen Steck and John Salathé, up the north face of Sentinel Rock in Yosemite Valley. They climbed mostly free using occasional direct aid pitons on some pitches, and a blank wall halfway up required a 30-foot bolt ladder. It was the longest and most difficult route in Yosemite in 1950. The route was repeated several times in the 50s using less and less aid. In 1959, Royal Robbins and Tom Frost did it all free except for the short bolt ladder, producing the most strenuous long free climb in America, with 6 pitches of 5.10a or 5.9, and many tiring 5.8 leads. In 1970, Steve Wunsch and Jim Erickson discovered a long finger/hand-size crack to the left of the bolt ladder, adding yet another 5.9+ pitch, which allowed the wall to be climbed totally free. In 1973, Henry Barber made the fi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
