Alpine Butterfly Knot
The butterfly loop, also known as lineman's loop, butterfly knot, alpine butterfly knot and lineman's rider, is a knot used to form a fixed loop in the middle of a rope. Tied in the bight, it can be made in a rope without access to either of the ends; this is a distinct advantage when working with long climbing ropes. The butterfly loop is an excellent mid-line rigging knot; it handles multi-directional loading well and has a symmetrical shape that makes it easy to inspect. In a climbing context it is also useful for traverse lines, some anchors, shortening rope slings, and for isolating damaged sections of rope. History The earliest known presentation of the knot was in A.A. Burger's 1914 work ''Rope and Its Uses'', included in an agricultural extension bulletin from what is now Iowa State University. Burger called the knot a lineman's rider stating it was often used by "linemen and especially telephone men". The knot's security and ability to withstand tension in any dir ...

Carabiner
A carabiner or karabiner (), often shortened to biner or to crab, colloquially known as a (climbing) clip, 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 comes from the German language, German , short for , meaning "carbine hook," as the device was used by carabiniers to attach their carbines to their belts. Use Carabiners are widely used in rope-intensive activities such as climbing, fall arrest systems, arboriculture, caving, sailing, hot air ballooning, hot-air ballooning, rope rescue, construction, industrial rope access, 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-carabiners, carabiner keyrings and ot ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sling (climbing Equipment)
A sling is an item of climbing equipment consisting of a tied or sewn loop of webbing. These can be wrapped around sections of rock, hitched to other pieces of equipment, or tied directly to a tensioned line using a Prusik style knot. They may be used as anchors, to extend an anchor to reduce rope drag, in anchor equalization, or to climb a rope. Uses In 1957 Jan and Herb Conn wrote an article titled "the versatile runner" with a long list of uses, which is still quite accurate: # Slings and now more often 3-foot alpine draws or shorter quickdraws are used in-between pieces of protection and the rope to minimize rope drag # Hitch around a chock stone or a tree to use as passive protectionConn, Jan and Herb (November 1957). ''The versatile runner'' - Summit (PDF) # Clove hitch around chicken heads or sling around horns # Longer slings or cordelettes can be used for equalized belay stations # Slings can be used as improvised "personal anchor system" attaching climber di ...

List Of Knots
This list of knots includes many alternative names for common knots and lashings. Knot names have evolved over time, and there are many conflicting or confusing naming issues. The overhand knot, for example, is also known as the thumb knot. The figure-eight knot is also known as the Savoy knot or the Flemish knot. A * Aberdeen knot - preferred for closure of intradermal sutures * Adjustable bend – can be easily lengthened or shortened * Adjustable grip hitch – a simple hitch which may easily be shifted up and down the rope while slack * Albright special – used to tie two different diameters of line together, for instance to tie monofilament to braid *Alpine butterfly (also known as a butterfly loop) – a static loop mostly used by mountain climbers and rappellers for securing a carabiner to static rope * Alternate ring hitching – covering a ring in hitching can prevent damage * Anchor bend – attaching a rope to a ring or similar termination * Angler's loop – ...

Clifford Warren Ashley
Clifford Warren Ashley (December 18, 1881 – September 18, 1947) was an American artist, author, sailor, and knot expert. Life Ashley was born in New Bedford, Massachusetts, son of Abiel Davis Ashley and Caroline Morse Ashley. He married Sarah Scudder Clark in 1932, with whom he had two daughters, one of whom is practicing painter Jane Ashley. He also adopted his wife's daughter from a previous marriage. He died in Westport Point, Massachusetts in 1947, two years after having a debilitating stroke. Education and early work Taking an interest in art while still in high school, he went on to attend the Eric Pape Art School in Boston. In the summer of 1901 Ashley, along with friends N.C. Wyeth and Henry J. Peck, studied under George Noyes in Annisquam, Massachusetts. In the fall, he went on to become a student of Howard Pyle's school in Wilmington, Delaware. Pyle helped secure commissions for his students, and Ashley's early work included book frontispieces and illustrat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Alpine Club (UK)
The Alpine Club was founded in London on 22 December 1857 and is the world's first list of alpine clubs, mountaineering club. The primary focus of the club is to support mountaineers who climb in the Alps and the Greater Ranges of the world's mountains. Current activities Though the club organises some UK-based meets and indoor lectures, its primary focus has always tended towards mountaineering overseas. It is associated more with exploratory mountaineering than with purely technical climbing (the early club was once dismissed as doing very little climbing but "a lot of walking steeply uphill"). These higher technical standards were often to be found in offshoots such as the 'Alpine Climbing Group' (ACG), which was founded in 1952 and merged with the Alpine Club in 1967; the AGC is aimed at those "who aspire to establish or repeat technically difficult climbs or undertake exploratory expeditions". The club continues to encourage and sponsor mountaineering expeditions through ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Alpine Journal
The ''Alpine Journal'' (''AJ'') is an annual publication by the Alpine Club of London. It is the oldest mountaineering journal in the world. History The journal was first published on 2 March 1863 by the publishing house of Longman in London, with Hereford Brooke George as its first editor. It was a replacement for ''Peaks, Passes, and Glaciers'', which had been issued in two series: in 1858 (with John Ball as editor), and 1862 (in two volumes, with Edward Shirley Kennedy as editor). The journal covers all aspects of mountains and mountaineering, including expeditions, adventure, art, literature, geography, history, geology, medicine, ethics and the mountain environment, and the history of mountain exploration, from early ascents in the Alps, exploration of the Himalaya and the succession of attempts on Mount Everest, to present-day exploits. Online access Journal volumes since 1926 (bar the current issue) are freely available online. Digital scans of earlier volumes of the ...

Butterflies
Butterflies are winged insects from the lepidopteran superfamily Papilionoidea, characterized by large, often brightly coloured wings that often fold together when at rest, and a conspicuous, fluttering flight. The oldest butterfly fossils have been dated to the Paleocene, about 56 million years ago, though molecular evidence suggests that they likely originated in the Cretaceous. Butterflies have a four-stage life cycle, and like other holometabolous insects they undergo complete metamorphosis. Winged adults lay eggs on the food plant on which their larvae, known as caterpillars, will feed. The caterpillars grow, sometimes very rapidly, and when fully developed, pupate in a chrysalis. When metamorphosis is complete, the pupal skin splits, the adult insect climbs out, expands its wings to dry, and flies off. Some butterflies, especially in the tropics, have several generations in a year, while others have a single generation, and a few in cold locations may take sever ...

Mountaineering
Mountaineering, mountain climbing, or alpinism is a set of outdoor activities that involves ascending mountains. Mountaineering-related activities include traditional outdoor climbing, skiing, and traversing via ferratas that have become mountain sports, sports in their own right. Indoor climbing, sport climbing, and bouldering are also considered variants of mountaineering by some, but are part of a wide group of mountain sports. Unlike most sports, mountaineering lacks widely applied formal rules, regulations, and governance; mountaineers adhere to a large variety of techniques and philosophies (including grade (climbing), grading and climbing guidebook, guidebooks) when climbing mountains. Numerous local alpine clubs support mountaineers by hosting resources and social activities. A federation of alpine clubs, the International Climbing and Mountaineering Federation (UIAA), is the International Olympic Committee-recognized world organization for mountaineering and climbing.

Lineman (technician)
A lineworker (also called a lineman or powerline worker) constructs and maintains the electric transmission and distribution facilities that deliver electrical energy to industrial, commercial, and residential establishments. A lineworker installs, services, and emergency repairs electrical lines in the case of lightning, wind, ice storm, or ground disruptions. Whereas those who install and maintain electrical wiring inside buildings are electricians, lineworkers generally work at outdoor installations. History The occupation had begun in 1844 when the first telegraph wires were strung between Washington, D.C., and Baltimore carrying the famous message of Samuel Morse, "What hath God wrought?" The first telegraph station was built in Chicago in 1848, by 1861 a web of lines spanned the United States and in 1868 the first permanent telegraph cable was successfully laid across the Atlantic Ocean. Telegraph lines could be strung on trees, but wooden poles were quickly adopted as ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
