Tree climbing is a recreational or functional activity consisting of ascending and moving around in the crown of trees. A rope and harness can be used to ensure the safety of the climber, other equipment can be used depending on the experience and skill of the tree climber. Some tree climbers take special hammocks called Treeboats and Portaledges with them into the canopies where they can enjoy a picnic or nap. Some tree-climbers employ a mixture of techniques and gear derived from rock climbing and caving and these techniques are used to climb trees for other purposes, tree care, animal rescue and activism. Children commonly climb trees for play without the use of equipment, professional arborists have been climbing trees since the late 19th century in the UK and North America. Tree climbing as a recreational activity using modern climbing equipment emerged in the early 1980s in USA. In 1983, Peter Treeman Jenkins, an active arborist and retired rock climber, founded Tree Climbers International, TCI eventually developed written safety and training rules for tree climbing which are used to this day.
Now there are numerous organizations promoting tree climbing around the world, from those initial meetings, GOTC was formed and incorporated as a charitable, nonprofit organization. Today, GOTC provides training curricula and safe climb guidelines in use worldwide and adopted by experiential organizations including the AEE. Climbing a tree every day for a year, or for longer, has become a challenge taken up by several artists, Todd Smith from Louisville, KY, USA, climbed a tree every day for 3 years. Henrik G Dahle, invited people to climb with him and interviewed people in the canopy of trees, including former 365 tree climber Leo Murray of Monkeydo, who now facilitates tree top adventures. Other artists include Christopher B Gray from Connecticut, USA, Kamila Wajda from Przybowka and Cecylia Malik from Kraków, many different techniques are used to climb trees depending on the climbers individual style and preferences. Of course free tree climbing has been practiced throughout the history of the human race, technologically-aided tree climbing is performed by lapping a long rope over a limb and ascending the fallen end using a friction knot tied from initial ties excess tail.
This is done remotely from the ground utilizing a throw weight, the throw weight is a small canvas sack filled with shot and adorned with a ring on one end for attaching a lightweight pilot line. It is launched toward the targeted branch, once over the branch, the weight must return to the ground, and may have to be manipulated so as to isolate a single anchor point, or for SRT into an optimal redirect. The throw bag is removed, the climbing line is tied on. The doubled-rope technique is used to belay the climber in such a way that the rope can be retrieved without going back up the tree. One end of the rope is fastened to the saddle, from there the rope passes around the tree and back to a friction hitch
A climbing competition, sometimes shortened to comp, is usually held indoors on purpose built climbing walls. There are three types of climbing competition, lead and bouldering. In lead climbing, the start at the bottom of a route and must climb within a certain time frame. Speed climbing can either be an individual or team event, the person or team that can climb a route the fastest is the winner. Bouldering competitions consist of climbing short problems with the emphasis on number of problems completed, in the United States, the American Bouldering Series organizes regional and national events. Sport climbing will be in the Olympic Games for the first time in 2020, Lead is the most common type of sport climbing. Competitors climb a long, difficult route designed and set by the route setter, all standard Lead competitions consist of three rounds, qualifications and finals. In the qualification round competitors climb 2 similar routes flash, meaning there is no isolation and their rank will be calculated as the square root of their rank on either route multiplied by each other.
In the case of ties, the rank from the previous round is taken into account. In the Finals, and if the tie is not broken using the countback process, in lead, climbers are belayed from below, and are required to clip quickdraws along the route. The route must be climbed within a time limit, usually 6 minutes. 26 athletes qualify for the Semifinal,8 proceed to the Final, Speed is the only factor that counts in the Speed Climbing event. Competitors climb a slightly overhanging IFSC certified vertical piste with belaying from the top, since 2007 the IFSC has created a standard wall for the world record. The climbing time is determined by mechanical-electric timing but manual timing is possible, when mechanical-electric timing is used, the climbing time shall be measured with an accuracy of 0.01 second. As of 12.09.2014, Ukrainian climber Danyl Boldyrev holds the mens 15 meter speed world record,5.60 seconds, iuliia Kaplina from Russia holds the womens 15-meter speed record at 7.53 seconds. The new Team Speed discipline was introduced as a showcase for the 2011 World Championship.
It is a competition with teams of three. The teams are made up of 3 athletes of the same sex, before the 2012 set of rules was introduced, the teams had to be mixed sexes
University of Colorado Boulder
The University of Colorado Boulder is a public research university located in Boulder, United States. It is the university of the University of Colorado system and was founded five months before Colorado was admitted to the Union in 1876. In 2015, the university consisted of nine colleges and schools and offered over 150 academic programs, twelve Nobel Laureates, nine MacArthur Fellows, and 20 astronauts have been affiliated with CU Boulder as students, researchers, or faculty members in its history. The university received nearly $454 million in sponsored research in 2010 to fund programs like the Laboratory for Atmospheric and Space Physics, the Colorado Buffaloes compete in 17 varsity sports and are members of the NCAA Division I Pac-12 Conference. The Buffaloes have won 28 national championships,20 in skiing, seven total in mens and womens cross country, approximately 1,500 students participate in 34 intercollegiate club sports annually as well. Two cities competed for the site of the University of Colorado, the consolation prize for the losing city was to be home of the new Colorado State Prison.
Cañon City was at a disadvantage as it was already the home of the Colorado Territorial Prison, the cornerstone of the building that became Old Main was laid on September 20,1875. The doors of the university opened on September 5,1877, at the time, there were few high schools in the state that could adequately prepare students for university work, so in addition to the University, a preparatory school was formed on campus. In the fall of 1877, the student body consisted of 15 students in the proper and 50 students in the preparatory school. There were 38 men and 27 women, and their ages ranged from 12–23 years, during World War II, Colorado was one of 131 colleges and universities nationally that took part in the V-12 Navy College Training Program which offered students a path to a navy commission. The main CU Boulder campus is located south of the Pearl Street Mall and it consists of academic and residential buildings as well as research facilities. The East Campus is about a mile from the main campus and is composed mainly of athletic fields.
CU Boulders distinctive architecture style, known as Tuscan Vernacular Revival, was designed by architect Charles Klauder. A month or so after approval, Klauder updated his design by sketching in a new wrap of rough, textured sandstone walls with sloping, multi-leveled red-tiled roofs and Indiana limestone trim. This formed the basis of a style which was used in the design of fifteen other buildings between 1921 and 1939. The sandstone used in the construction of all the buildings on campus was selected from a variety of front range mountain quarries. In 2011, Travel+Leisure named the Boulder campus as one of the most beautiful campuses in the United States. Currently Freshmen and others attending the University of Colorado Boulder have an option of 24 on-, Residence halls have 17 varieties of room types from singles to four-person rooms and others with apartment style amenities
A belay device is a mechanical piece of climbing equipment used to control a rope during belaying. It is designed to improve safety for the climber by allowing the belayer to manage their duties with minimal physical effort. With the right belay device, a small, weak climber can easily arrest the fall of a much heavier partner, belay devices act as a friction brake, so that when a climber falls with any slack in the rope, the fall is brought to a stop. Belay devices generally have two modes of operation, in the first mode, the rope is relatively free to be paid in/out by the belayer and this rubbing slows the rope, but generates heat. Some types of devices can transition between these modes without the belayer taking any action, others require the belayer to hold or pull the rope in a particular direction to arrest a fall. Belay devices usually attach to the harness of the belayer via a carabiner, some belay devices can be used as descenders for a controlled descent on a rope, that is abseiling or rappeling.
Many belay devices can be used to either one rope. There are many reasons why the option might be chosen by a climber. There are devices on the market which allow a climber to climb solo in his or her climbing gym and this is a device that you feed a bight of rope through a hole or aperture and hook it into a locking carabiner on the harness. The Sticht plate was the first mechanical brake, named after its designer. It consists of a metal plate with a slot that allows a bight of rope to pass through to a locking carabiner. This locking carabiner is clipped to the belayer who is able to lock the rope at will. Some plates had two slots for double ropes, the slots could be different sizes for different diameter ropes e. g. 9mm and 11mm. A wide wire spring may be attached on one side to keep the plate away from the brake carabiner to ease feeding and taking in rope. A smaller hole is present for accessory cord to carry the device. Sticht plates are typically forged from aluminium alloy in a disc shape.
Sticht plates have become popular since more modern designs provide smoother control over the rope and are less prone to jamming. This type of device generally has a tubular or rectangular shape, as a result, this is generally the most common type of belay device used
Tufts University is a private research university incorporated in the municipality of Medford, United States. Tufts College was founded in 1852 by Christian Universalists who worked for years to open a nonsectarian institution of higher learning, Charles Tufts donated the land for the campus on Walnut Hill, the highest point in Medford, saying that he wanted to set a light on the hill. The name was changed to Tufts University in 1954, although the name remains the Trustees of Tufts College. For more than a century, Tufts was a small New England liberal arts college, the university is organized into ten schools, including two undergraduate degree programs and eight graduate divisions, on four campuses in the Boston metropolitan area and the French Alps. The university emphasizes active citizenship and public service in all of its disciplines and is known for its internationalism, among its schools is the United States oldest graduate school of international relations, the Fletcher School of Law and Diplomacy.
The School of the Museum of Fine Arts offers art programs affiliated with a major museum, the university maintains a campus in Downtown Boston which houses the medical and nutrition schools, affiliated with several medical centers in the area. Some of its programs have affiliations with the institutions of Harvard University. Tufts is a member of and athletically competes in the New England Small College Athletic Conference. Tufts accepted 14% of undergraduate applicants to the Class of 2020 from a pool of 20,223 and it is consistently ranked by U. S. News & World Report and Forbes as one of the top schools in the United States. In the 1840s, the Universalist Church wanted to open a college in New England and his 20-acre donation is still at the heart of Tufts now 150 acre campus, straddling Somerville and Medford. During his tenure, Ballou spent a year travelling and studying in the United Kingdom, the methods of instruction which he initiated were based on the tutorials that were conducted in the University of Oxford and the University of Edinburgh.
Now more than 160 years old, Tufts is the third oldest college in the Boston area and that building now bears Ballous name. The campus opened in August 1854, President Ballou died in 1861 and was succeeded by Alonzo Ames Miner. Though not a graduate, his presidency was marked by several advances. These include the establishment of schools for Tufts which include Goddard Seminary, Westbrook Seminary. During the Civil War the college supported the Union cause. The mansion of Major George L. Stearns which stood on part of the campus was a station on the Underground Railroad, in addition to having the largest classes spring up,63 graduates served in the Union army. The first course of a program leading to a degree in civil engineering was established in 1865
Top rope climbing
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. Top-roping is often done on routes that cannot be 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 and it is the most common style used at indoor climbing walls and is used in situations where other methods would be unsafe or environmentally damaging. For example, in Kent and Sussex in south-east England, the rock is soft and prone to erosion. There, top-roping from permanent anchors and solo climbing are the forms of ascent allowed. A dynamic rope should be used for the climbers, for anchors which are set back from the cliff edge, extending the anchor using multiple slings, a long adjustable-length sling, or a length of static line is common. Most practitioners run the rope through two screwgate carabiners attached to the anchor, to provide backup in case one becomes undone.
In the interests of safety at least two separate and redundant anchor points should be used, with forces distributed as evenly between them as possible. In the photo above, it can be seen only the two locking carabiners protrude over the cliff edge, allowing the climbing rope a relatively free run from belayer to climber. Many novice climbers initially experience the sport through top-roping, university of Oregon Outdoor Pursuits Program, Climbing Anchors
Rock climbing is an activity in which participants climb up, down or across natural rock formations or artificial rock walls. The goal is to reach the summit of a formation or the endpoint of a usually pre-defined route without falling. Due to the length and extended endurance required and because accidents are likely to happen on descent than ascent. It is very rare for a climber to downclimb, especially on the larger multiple pitches, professional Rock climbing competitions have the objectives of either completing the route in the quickest possible time or attaining the farthest point on an increasingly difficult route. Scrambling, another activity involving the scaling of hills and similar formations, is similar to rock climbing, rock climbing is generally differentiated by its sustained use of hands to support the climbers weight as well as to provide balance. Rock climbing is a physically and mentally demanding sport, one that often tests a climbers strength, agility and it can be a dangerous activity and knowledge of proper climbing techniques and usage of specialized climbing equipment is crucial for the safe completion of routes.
Because of the range and variety of rock formations around the world. Paintings dating from 200 BC show Chinese men rock climbing China woop woop, in early America, the cliff-dwelling Anasazi in the 12th century were thought to be excellent climbers. Early European climbers used rock climbing techniques as a required to reach the summit in their mountaineering exploits. In the 1880s, European rock climbing become an independent pursuit outside of mountain climbing, Rock climbing evolved gradually from an alpine necessity to a distinct athletic activity. However, climbing techniques and ethical considerations have evolved steadily, free climbing, climbing using holds made entirely of natural rock while using gear solely for protection and not for upward movement, is the most popular form of the sport. Free climbing has since divided into several sub-styles of climbing dependent on belay configuration. Over time, grading systems have created in order to compare more accurately the relative difficulties of the rock climbs.
In How to Rock Climb, John Long notes that for moderately skilled climbers simply getting to the top of a route is not enough, in rock climbing, style refers to the method of ascending the cliff. There are three styles of climbing, on-sight and redpoint. To on-sight a route is to ascend the wall without aid or any foreknowledge and it is considered the way to climb with the most style. Flashing is similar to on-sighting, except that the climber has previous information about the route including talking about the beta with other climbers, redpointing means to make a free ascent of the route after having first tried it. Free climbing is typically divided into styles that differ from one another depending on the choice of equipment used
Free solo climbing
Unlike in bouldering, free soloists typically climb above safe heights, where a fall would always result in serious injury or death. In ordinary free climbing, safety gear is used to protect from falls, other reasons given are the intense concentration required and, for some, the adrenaline rush. The practice is confined to routes familiar to the climber. However, inherent risks such as rocks or sudden change in weather are always present. The sport has produced a number of practitioners, made famous by photos of a climber totally alone. Two of the most famous free soloists, Alain Robert, and Dan Goodwin, have scaled dozens of skyscrapers around the world — a sport known as buildering —, there are few climbers who have free solo climbed in the 5.14 range. This list does not include highball boulder ascents because the climbers here did not use any padding or spotters, there is some debate on the blurred line between highball bouldering and short free solo climbs. 5. 14b - Darwin Dixit - Margalef, Spain - Dave MacLeod,5.

A harness secures a person to a rope or an anchor point. In its simplest form, a harness can be made from a length of rope or a nylon webbing tied round the waist, more sophisticated harnesses exist in many patterns, designed to give greater comfort and security, and more options for carrying equipment. While harnesses can be improvised, it is common to use commercially produced harnesses. The invention of the climbing harness has been attributed to Jeanne Immink, some of the first climbing harnesses were devised in the U. K. in the early 1960s by Alan Waterhouse, Paul Seddon and Tony Howard who went on to form the Troll climbing equipment manufacturers. A harness designed by British climber Don Whillans was made by Troll for the 1970 Annapurna South Face Expedition and it went into mass production shortly afterwards and soon became popular worldwide. A sit harness consists of a waist belt and two leg loops which are connected in the front of the hips through a permanent webbing loop called a belay loop.
These are the most commonly used harnesses for recreational such as abseiling and rock climbing. A chest harness is worn around the shoulders, usually with a sit harness so as to provide an attachment point. This attachment point allows for balance in some situations such as when carrying a heavy pack. A full-body harness is the combination of a sit harness and a chest harness which are permanently or semi-permanently connected to each other and this kind of harness normally offers a wide range of attachment points. It is most commonly used in situations, and commonly used by small children instead of a sit harness. Most of the harnesses is generally made from webbing and this webbing is often nylon webbing as polyester webbing doesnt hold triglides and d-rings as well, and its easier to untie nylon webbing. The webbing is tubular webbing, instead of flat webbing. Harness List of climbing knots How to choose a climbing harness
Climbing is the activity of using ones hands, feet, or any other part of the body to ascend a steep object. It is done recreationally, competitively, in trades that rely on it and it is done indoors and out, on natural and manmade structures. Climbing activities include, Ascending boulders or small outcrops, often with climbing shoes, Climbing along canyons for sport or recreation. Chalk climbing, Ascending chalk cliffs uses some of the techniques as ice climbing. Competition Climbing, A formal, competitive sport of recent origins, competition Climbing has three major disciplines, Lead and Speed. Ice climbing, Ascending ice or hard snow formations using special equipment, usually ice axes, techniques of protecting the climber are similar to those of rock climbing, with protective devices adapted to frozen conditions. Indoor climbing, Top roping, lead climbing, and bouldering artificial walls with bolted holds in a climbing gym, Ascending mountains for sport or recreation. It often involves rock and/or ice climbing, pole climbing, Climbing poles and masts without equipment.
Lumberjack tree-trimming and competitive tree-trunk or pole climbing for speed using spikes, rock climbing, Ascending rock formations, often using climbing shoes and a chalk bag. Equipment such as ropes, nuts and camming devices are normally employed, rope access, Industrial climbing, usually abseiling, as an alternative to scaffolding for short works on exposed structures. Rope climbing, Climbing a short, thick rope for speed, not to be confused with roped climbing, as in rock or ice climbing. Scrambling which includes rock climbing, and is considered part of hillwalking. Sport climbing is a form of climbing that relies on permanent anchors fixed to the rock. Top roping, Ascending a rock climbing route protected by a rope anchored at the top and protected by a belayer below Traditional climbing is a form of climbing without fixed anchors and bolts. Climbers place removable protection such as camming devices, free solo climbing, Climbing without ropes or protection. Tree climbing, Recreationally ascending trees using ropes and other protective equipment, a tower climber is a professional who climbs broadcasting or telecommunication towers or masts for maintenance or repair.
Rock and tree climbing all usually use ropes for safety or aid, pole climbing and rope climbing were among the first exercises to be included in the origins of modern gymnastics in the late 18th century and early 19th century
Traditional climbing, or trad climbing, is a style of rock climbing in which a climber or group of climbers place all gear required to protect against falls, and removes it when a passage is complete. Traditional bolted face climbing means the bolts were placed on lead and/or with hand drills, the bolts tend to be much farther apart than sport climbs. For example, a trad bolted routes may have bolts from 15–75 feet apart, a sport route may have bolts from 3–10 feet apart, similar to a rock climbing gym. The term seems to be coined by Tom Higgins in the piece Tricksters, a trad climber is called a traditionalist. Characterizing climbing as traditional distinguishes it from bolted climbing-either trad bolted or sport climbing, in trad climbing, a leader ascends a section of rock placing his or her own protective devices while climbing. John Longs 1989 technique manual How to Rock Climb used the sport climbing repeatedly in reference to what is now considered traditional climbing. This evolution in climbing ethics has been attributed to the efforts of Yvon Chouinard and many others, the term gear in climbing generally refers to equipment used during climbs.
Gear or protection are mechanical devices that provide safety, either by allowing greater stability in making a move or by dampening force, the suitability of individual types of gear depends on the surface and formation of the rock face. The phrase placing gear denotes the act of setting a piece of gear into the rock face, in the event of a fall, the gear acts as a catch-point for the rope, thus preventing the climber from hurtling to the ground. Being run out refers to the situation where the distance from the position to the last piece of gear is far enough that the climber will receive little, if any. Nuts started being developed in the 1950s in the UK, with the pieces being made from discarded machine nuts with slings threaded through them. These gradually developed into purpose built nuts, prior to about 1970 in the United States, climbing relied mainly on pitons, other types of gear such as nuts, Hexcentrics and spring-loaded cams were largely unknown or did not exist. As other variants of climbing were not nominally in existence as well, all climbing was in effect trad climbing until the early 1980s when sport climbing emerged in Europe, since the 1970s, developments in protective gear have made climbing much safer and more dynamic.
Modern traditional climbs only occasionally have fixed gear, except in the case where cracks are lacking to place adequate removable gear and it is considered bad style to install new protection bolts or pitons on existing climbs that can be completed without them. Many of the existing pitons and bolts from the first ascents of routes done many years ago, are now considered to be in bad condition having suffered from the weathering. This is especially present on sea cliffs where the nature of the air has sped up the oxidisation to create rust. A number of knots are required for climbing, to create anchors, to tie in the climbers. Water knot is used for connecting two pieces of webbing together, double bowline is used for tying in, or anchoring around a fixed object
A wide range of equipment is used during rock or any other type of climbing. The most popular types of climbing equipment are briefly described in this article, the article on protecting a climb describes equipment commonly used to protect a climber against the consequences of a fall. See the Glossary of climbing terms for more equipment descriptions, climbing ropes are typically of kernmantle construction, consisting of a core of long twisted fibres and an outer sheath of woven coloured fibres. The core provides about 80% of the strength, while the sheath is a durable layer that protects the core. Ropes used for climbing can be divided into two classes, dynamic ropes and low elongation ropes, dynamic ropes are designed to absorb the energy of a falling climber, and are usually used as Belaying ropes. When a climber falls, the rope stretches, reducing the force experienced by the climber, their belayer. Low elongation ropes stretch much less, and are used in anchoring systems. They are used for abseiling and as fixed ropes climbed with ascenders, modern webbing or tape is made of nylon or Spectra/Dyneema, or a combination of the two.
Climbing-specific nylon webbing is generally tubular webbing, that is, it is a tube of nylon pressed flat and it is very strong, generally rated in excess of 9 kN, or about 2,020 pounds of force. Dyneema is even stronger, often rated above 20 kN and as high as 27 kN, in 2010, UK-based DMM performed fall factor 1 and 2 tests on various Dyneema and Nylon webbings, showing Dyneema slings can fail even under 60 cm falls. Tying knots in Dyneema webbing was proven to have reduced the amount of supported force by as much as half. When webbing is sewn or tied together at the ends, it becomes a sling or runner and these loops are made one of two ways—sewn or tied. Both ways of forming runners have advantages and drawbacks, and it is for the climber to choose which to use. Generally speaking, most climbers carry a few of both types and it is important to note that only nylon can be safely knotted into a runner, Dyneema is always sewn because the fibers are too slippery to hold a knot under weight. Webbing has many such as, Extending the distance between protection and a tie-in point.
An anchor around a tree or rock, protecting a rope that hangs over a sharp edge. Carabiners are metal loops with spring-loaded gates, used as connectors, once made primarily from steel, almost all carabiners for recreational climbing are now made from a light weight aluminum alloy. Steel carabiners are much heavier, but harder wearing, and therefore are used by instructors when working with groups
