Henry Barber (rock 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 ...

Nut (climbing)
In rock climbing, a nut (or ''chock'' or ''chockstone'') 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 offset if several are placed at a ti ...

Nylon
Nylon is a generic designation for a family of synthetic polymers composed of polyamides ( repeating units linked by amide links).The polyamides may be aliphatic or semi-aromatic. Nylon is a silk-like thermoplastic, generally made from petroleum, that can be melt-processed into fibers, films, or shapes. Nylon polymers can be mixed with a wide variety of additives to achieve many property variations. Nylon polymers have found significant commercial applications in fabric and fibers (apparel, flooring and rubber reinforcement), in shapes (molded parts for cars, electrical equipment, etc.), and in films (mostly for food packaging). History DuPont and the invention of nylon Researchers at DuPont began developing cellulose based fibers, culminating in the synthetic fiber rayon. DuPont's experience with rayon was an important precursor to its development and marketing of nylon. DuPont's invention of nylon spanned an eleven-year period, ranging from the initial research pr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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] |
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] |
East Germany
East Germany, officially the German Democratic Republic (GDR; german: Deutsche Demokratische Republik, , DDR, ), was a country that existed from its creation on 7 October 1949 until its dissolution on 3 October 1990. In these years the state was a part of the Eastern Bloc in the Cold War. Commonly described as a communist state, it described itself as a socialist "workers' and peasants' state".Patrick Major, Jonathan Osmond, ''The Workers' and Peasants' State: Communism and Society in East Germany Under Ulbricht 1945–71'', Manchester University Press, 2002, Its territory was administered and occupied by Soviet forces following the end of World War II—the Soviet occupation zone of the Potsdam Agreement, bounded on the east by the Oder–Neisse line. The Soviet zone surrounded West Berlin but did not include it and West Berlin remained outside the jurisdiction of the GDR. Most scholars and academics describe the GDR as a totalitarian dictatorship. The GDR was establish ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dresden
Dresden (, ; Upper Saxon: ''Dräsdn''; wen, label=Upper Sorbian, Drježdźany) is the capital city of the German state of Saxony and its second most populous city, after Leipzig. It is the 12th most populous city of Germany, the fourth largest by area (after Berlin, Hamburg and Cologne), and the third most populous city in the area of former East Germany, after Berlin and Leipzig. Dresden's urban area comprises the towns of Freital, Pirna, Radebeul, Meissen, Coswig, Radeberg and Heidenau and has around 790,000 inhabitants. The Dresden metropolitan area has approximately 1.34 million inhabitants. Dresden is the second largest city on the River Elbe after Hamburg. Most of the city's population lives in the Elbe Valley, but a large, albeit very sparsely populated area of the city east of the Elbe lies in the West Lusatian Hill Country and Uplands (the westernmost part of the Sudetes) and thus in Lusatia. Many boroughs west of the Elbe lie in the foreland of the Ore Mounta ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 climb 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 5.11. That was at a time when the hardest free climbing grade in the United States was 5.7. At the age of 25, he made the first ascent of the ''Fleischbank'' in Tyrol, which was proclaimed the hardest rock climb done at that time. Wiessner's physical qualities were atypical of mountaineering. He was tall, slope-shouldered and stocky. He had a wide and friendly gri ...

Sentinel Rock
Sentinel Rock is a granitic peak in Yosemite National Park, California, United States. It towers over Yosemite Valley, opposite Yosemite Falls. Sentinel Rock lies northwest of Sentinel Dome. How it was formed Sentinel Rock formed when masses of rock split off Yosemite Valley's south-side cliff In geography and geology, a cliff is an area of rock which has a general angle defined by the vertical, or nearly vertical. Cliffs are formed by the processes of weathering and erosion, with the effect of gravity. Cliffs are common on co ..., along steep joints trending nearly east–west.

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] |
