Ray Jardine
Ray Jardine (born in 1944) is an American rock climber who, along with Bill Price, in May 1979, was the first to free climb the ''West Face'' of El Capitan in Yosemite Valley. Jardine is also a mountaineer, sea kayaker, sailor, hang glider pilot, sailplane pilot, small aircraft pilot, skydiver, long-distance hiker, bicyclist, motorcyclist, and gear designer. Jardine is noted for inventing and developing the spring-loaded camming devices called Friends with the late Mark Vallance, which revolutionized rock climbing in the late 1970s. He is also noted for his major contributions to the ultralight backpacking community through his books and his "make-it-yourself" gear company, Ray-Way Products. Early life Born in Colorado Springs, Colorado, as a youth, Jardine climbed Colorado's Pikes Peak dozens of times, mostly solo, and with the Boy Scouts of America. In 1959, Jardine achieved Eagle Scout (Boy Scouts of America). During his Junior and Senior years (1959-1961) at General William ...

Rock Climbing
Rock climbing is a sport in which participants climb up, across, or down natural rock formations. The goal is to reach the summit of a formation or the endpoint of a usually pre-defined route without falling. Rock climbing is a physically and mentally demanding sport, one that often tests a climber's strength, endurance, agility and balance along with mental control. Knowledge of proper climbing techniques and the use of specialized climbing equipment is crucial for the safe completion of routes. Because of the wide range and variety of rock formations around the world, rock climbing has been separated into several different styles and sub-disciplines, such as scrambling, bouldering, sport climbing, and trad (traditional) climbing another activity involving the scaling of hills and similar formations, differentiated by the rock climber's sustained use of hands to support their body weight as well as to provide balance. Rock climbing competitions have the objectives of either ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Drafter
A drafter (also draughtsman / draughtswoman in British and Commonwealth English, draftsman / draftswoman or drafting technician in American and Canadian English) is an engineering technician who makes detailed technical drawings or plans for machinery, buildings, electronics, infrastructure, sections, etc. Drafters use computer software and manual sketches to convert the designs, plans, and layouts of engineers and architects into a set of technical drawings. Drafters operate as the supporting developers and sketch engineering designs and drawings from preliminary design concepts. Overview In the past, drafters sat at drawing boards and used pencils, pens, compasses, protractors, triangles, and other drafting devices to prepare a drawing by hand. From the 1980s through 1990s, board drawings were going out of style as the newly developed computer-aided design (CAD) system was released and was able to produce technical drawings at a faster pace. Many modern drafters now use co ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Professional Association Of Diving Instructors
The Professional Association of Diving Instructors (PADI) is a recreational diving membership and diver training organization founded in 1966 by John Cronin and Ralph Erickson. Cronin was originally a NAUI instructor who decided to form his own organization with Erickson, and to break diver training down into several modular courses instead of the single universal course then prevalent. PADI courses range from entry level to relatively advanced recreational diver certification, several specialized diving skills courses, usually connected with specific equipment or conditions, some diving related informational courses and a range of recreational diving instructor certifications. They also offer various technical diving courses. As of 2022, PADI is reported to have issued 29 million scuba certifications. History In 1966, PADI was founded by John Cronin and Ralph Erickson. In 2006, PADI was severely criticized by a Coroner's court in the United Kingdom for providing what ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Caribbean
The Caribbean (, ) ( es, El Caribe; french: la Caraïbe; ht, Karayib; nl, De Caraïben) is a region of the Americas that consists of the Caribbean Sea, its islands (some surrounded by the Caribbean Sea and some bordering both the Caribbean Sea and the North Atlantic Ocean) and the surrounding coasts. The region is southeast of the Gulf of Mexico and the North American mainland, east of Central America, and north of South America. Situated largely on the Caribbean Plate, the region has more than 700 islands, islets, reefs and cays (see the list of Caribbean islands). Island arcs delineate the eastern and northern edges of the Caribbean Sea: The Greater Antilles and the Lucayan Archipelago on the north and the Lesser Antilles and the on the south and east (which includes the Leeward Antilles). They form the West Indies with the nearby Lucayan Archipelago (the Bahamas and Turks and Caicos Islands), which are considered to be part of the Caribbean despite not bordering the Caribbe ...

Snorkeling
Snorkeling ( British and Commonwealth English spelling: snorkelling) is the practice of swimming on or through a body of water while equipped with a diving mask, a shaped breathing tube called a snorkel, and usually swimfins. In cooler waters, a wetsuit may also be worn. Use of this equipment allows the snorkeler to observe underwater attractions for extended periods with relatively little effort and to breathe while face-down at the surface. Snorkeling is a popular recreational activity, particularly at tropical resort locations. It provides the opportunity to observe underwater life in a natural setting without the complicated equipment and training required for scuba diving. It appeals to all ages because of how little effort is involved and is the basis of the two surface disciplines of the underwater sport of finswimming. Snorkeling is also used by scuba divers when on the surface, in underwater sports such as underwater hockey and underwater rugby, and as part of water-b ...

Scuba Diving
Scuba diving is a mode of underwater diving whereby divers use breathing equipment that is completely independent of a surface air supply. The name "scuba", an acronym for "Self-Contained Underwater Breathing Apparatus", was coined by Christian J. Lambertsen in a patent submitted in 1952. Scuba divers carry their own source of breathing gas, usually compressed air, affording them greater independence and movement than surface-supplied divers, and more time underwater than free divers. Although the use of compressed air is common, a gas blend with a higher oxygen content, known as enriched air or nitrox, has become popular due to the reduced nitrogen intake during long and/or repetitive dives. Also, breathing gas diluted with helium may be used to reduce the likelihood and effects of nitrogen narcosis during deeper dives. Open circuit scuba systems discharge the breathing gas into the environment as it is exhaled, and consist of one or more diving cylinders containing breat ...

Ketch
A ketch is a two- masted sailboat whose mainmast is taller than the mizzen mast (or aft-mast), and whose mizzen mast is stepped forward of the rudder post. The mizzen mast stepped forward of the rudder post is what distinguishes the ketch from a yawl, which has its mizzen mast stepped aft of its rudder post. In the 19th and 20th centuries, ketch rigs were often employed on larger yachts and working watercraft, but ketches are also used as smaller working watercraft as short as 15 feet, or as small cruising boats, such as Bill Hanna's Tahiti ketches or L. Francis Herreshoff's Rozinante and H-28. The name ketch is derived from ''catch''. The ketch's main mast is usually stepped further forward than the position found on a sloop. The sail plan of a ketch is similar to that of a yawl, on which the mizzen mast is smaller and set further back. There are versions of the ketch rig that only has a mainsail and a mizzen, in which case they are referred to as ''cat ketch''. More comm ...

The Nose (El Capitan)
''The Nose'' is one of the original technical climbing routes up El Capitan. Once considered impossible to climb, El Capitan is now the standard for big-wall climbing. It is recognized in the historic climbing text ''Fifty Classic Climbs of North America'' and considered a classic around the world. El Capitan has two main faces, the Southwest (on the left when looking directly at the wall) and the Southeast. Between the two faces juts a massive prow. While today there are numerous established routes on both faces, the most popular and historically famous route is ''The Nose'', which follows the massive prow. First ascents Once thought to be unclimbable, the high granite walls of Yosemite Valley began to see their first attempts and first ascents in the 1950s. One of the most coveted routes was the Northwest Face of Half Dome, and among those coveting it was Californian Warren Harding (Harding made an unsuccessful attempt on Half Dome in 1955, and returned for the 1957 season ...

Grade (climbing)
In rock climbing, mountaineering, and other climbing disciplines, climbers give a grade to a climbing route or boulder problem, intended to describe concisely the difficulty and danger of climbing it. Different types of climbing (such as sport climbing, bouldering or ice climbing) each have their own grading systems, and many nationalities developed their own, distinctive grading systems. There are a number of factors that contribute to the difficulty of a climb, including the technical difficulty of the moves, the strength, stamina and level of commitment required, and the difficulty of protecting the climber. Different grading systems consider these factors in different ways, so no two grading systems have an exact one-to-one correspondence. Climbing grades are inherently subjective.Reynolds Sagar, Heather, 2007, ''Climbing your best: training to maximize your performance'', Stackpole Books, UK, 9. They may be the opinion of one or a few climbers, often the first ascensioni ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Eldorado Canyon State Park
Eldorado Canyon State Park is part of the Colorado State Park system. It was established in 1978 and is located in Boulder County near the city of Boulder. The park consists of two areas, the Inner Canyon (developed area) and Crescent Meadows (undeveloped area). The park encompasses with a variety of recreation opportunities available. Eldorado Canyon is home to one of the world's most accessible and comprehensive rock climbing areas. This state park is open during daylight hours only, visitors are expected to leave before dusk. History Ute Indians were the first inhabitants into this area that is nestled against the foothills near Boulder. The Indians lived within the walls of the canyon because they provided protection from the harsh Colorado winters. Settlers soon followed in search of gold and agriculture. Eldorado Canyon is known for its geologic history dating back billions of years. Near the park’s entrance at the visitors center, there are rocks calculated to be over 1 ...

Tetons
The Teton Range is a mountain range of the Rocky Mountains in North America. It extends for approximately in a north–south direction through the U.S. state of Wyoming, east of the Idaho state line. It is south of Yellowstone National Park and most of the east side of the range is within Grand Teton National Park. One theory says the early French voyageurs named the range ' ("the three nipples") after the breast-like shapes of its peaks. Another theory says the range is named for the Teton Sioux (from Thítȟuŋwaŋ), also known as the Lakota people.Ullrich, Jan. (2008). ''New Lakota Dictionary''. Lakota Language Consortium. It is likely that the local Shoshone people once called the whole range ', meaning "many pinnacles". The principal summits of the central massif, sometimes referred to as the Cathedral Group, are Grand Teton (), Mount Owen (), Teewinot (), Middle Teton () and South Teton (). Other peaks in the range include Mount Moran (), Mount Wister (), Buck Mounta ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
