Terrain Park
A terrain park or snow park is an outdoor recreation area containing terrain that allows skiers, snowboarders and snowbikers to perform tricks. Terrain parks have their roots in skateparks and many of the features are common to both. From their inception to as recently as the 1980s, ski areas generally banned jumping and any kind of aerial maneuvers, usually under penalty of revoking the offender's lift ticket. By the 1990s, most areas provided snow features specifically catering to aerial snowsports. One of the first in-bounds terrain parks was the snowboard park built in 1990 at Vail's (Colorado) resort. The park was copied soon in other resorts. Today most resorts have terrain parks, with many having multiple parks of various difficulty. Some resorts are almost exclusively terrain parks such as Echo Mountain Park in Evergreen, Colorado and Snow Park in Wanaka, New Zealand. In Colorado there has been a recent trend for defunct resorts such as Squaw Pass (now Echo Mountain ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wintersports Terrain Park P1391
Winter sports or winter activities are competitive sports or non-competitive recreational activities which are played on snow or ice. Most are variations of skiing, ice skating and sledding. Traditionally, such games were only played in cold areas during winter, but artificial snow and artificial ice allow more flexibility. Playing areas and fields consist of either snow or ice. Synthetic ice, Artificial ice can be used to provide ice rinks for ice skating, ice hockey, para ice hockey, ringette, broomball, bandy, rink bandy, rinkball, and spongee in a milder climate. The sport of speed skating uses a frozen circular track of ice, but in some facilities the track is combined in an enclosed area used for sports requiring an ice rink or the rink itself is used. Alternatively, ice cross downhill uses a track with various levels of elevation and a combination of bends. Long distance skating ( "marathon skating") such as tour skating is only performed outdoors and uses the available na ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Skiers
Skiing is the use of skis to glide on snow. Variations of purpose include basic transport, a recreational activity, or a competitive winter sport. Many types of competitive skiing events are recognized by the International Olympic Committee (IOC), and the International Ski Federation (FIS). History Skiing has a history of almost five millennia. Although modern skiing has evolved from beginnings in Scandinavia, it may have been practiced more than 100 centuries ago in what is now China, according to an interpretation of ancient paintings. However, this continues to be debated. The word "ski" comes from the Old Norse word "skíð" which means to "split piece of wood or firewood". Asymmetrical skis were used in northern Finland and Sweden until at least the late 19th century. On one foot, the skier wore a long straight non-arching ski for sliding, and a shorter ski was worn on the other foot for kicking. The underside of the short ski was either plain or covered with animal ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Snowboarding
Snowboarding is a recreational and competitive activity that involves descending a snow-covered surface while standing on a snowboard that is almost always attached to a rider's feet. It features in the Winter Olympic Games and Winter Paralympic Games. Snowboarding was developed in the United States, inspired by skateboarding, sledding, surfing, and skiing. It became popular around the globe, and was introduced as a Winter Olympic Sport at Nagano in 1998 and featured in the Winter Paralympics at Sochi in 2014. , its popularity (as measured by equipment sales) in the United States peaked in 2007 and has been in a decline since. History The first snowboards were developed in 1965 when Sherman Poppen, an engineer in Muskegon, Michigan, invented a toy for his daughters by fastening two skis together and attaching a rope to one end so he would have some control as they stood on the board and glided downhill. Dubbed the "snurfer" (combining snow and surfer) by his wife Nancy, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Skatepark
A skatepark, or skate park, is a purpose-built recreational environment made for skateboarding, BMX, scootering, wheelchairs, and aggressive inline skating. A skatepark may contain half-pipes, handrails, funboxes, vert ramps, stairsets, quarter pipes, ledges, spine transfers, pyramids, banked ramps, full pipes, pools, bowls, snake runs, and any number of other objects. History The first skatepark in the world, Surf City, opened for business at 5140 E. Speedway in Tucson, Arizona on September 3, 1965. Patti McGee, Women's National Champion, attended the grand opening. The park had concrete ramps and was operated by Arizona Surf City Enterprises, Inc. A skatepark for skateboarders and skaters made of plywood ramps on a half-acre lot in Kelso, Washington, USA opened in April 1966. It was lighted for night use. California's first skatepark, the Carlsbad Skatepark opened on March 3, 1976. The World Skateboard Championships were held here on April 10, 1977. It operated un ...

Halfpipe
A half-pipe is a structure used in gravity extreme sports such as snowboarding, skateboarding, skiing, freestyle BMX, skating, and scooter riding. Overview The structure resembles a cross-section of a swimming pool, essentially two concave ramps (or quarter-pipes), topped by copings and decks, facing each other across a flat transition, also known as a ''tranny''. Originally half-pipes were half sections of a large diameter pipe. Since the 1980s, half-pipes contain an extended ''flat bottom'' between the quarter-pipes. The original style half-pipes are no longer built. Flat ground provides time to regain balance after landing and more time to prepare for the next trick. Half-pipe applications include leisure recreation, skills development, competitive training, amateur and professional competition, demonstrations, and as an adjunct to other types of skills training. A skilled athlete can perform in a half-pipe for an extended period of time by pumping to attain extreme speeds ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Noah Salasnek
Noah ''Nukh''; am, ኖህ, ''Noḥ''; ar, نُوح '; grc, Νῶε ''Nôe'' () is the tenth and last of the pre-Flood patriarchs in the traditions of Abrahamic religions. His story appears in the Hebrew Bible (Book of Genesis, chapters 5–9), the Quran and Baha'i writings. Noah is referenced in various other books of the Bible, including the New Testament, and in associated deuterocanonical books. The Genesis flood narrative is among the best-known stories of the Bible. In this account, Noah labored faithfully to build the Ark at God's command, ultimately saving not only his own family, but mankind itself and all land animals, from extinction during the Flood. Afterwards, God made a covenant with Noah and promised never again to destroy all the Earth's creatures with a flood. Noah is also portrayed as a "tiller of the soil" and as a drinker of wine.

Levi 293
Levi (; ) was, according to the Book of Genesis, the third of the six sons of Jacob and Leah (Jacob's third son), and the founder of the Israelite Tribe of Levi (the Levites, including the Kohanim) and the great-grandfather of Aaron, Moses and Miriam. Certain religious and political functions were reserved for the Levites. Origins The Torah suggests that the name ''Levi'' refers to Leah's hope for Jacob to ''join'' with her, implying a derivation from ''yillaweh'', meaning ''he will join'', but scholars suspect that it may simply mean ''priest'', either as a loan word from the Minaean ''lawi'u'', meaning ''priest'', or by referring to those people who were ''joined'' to the Ark of the Covenant. Another possibility is that the Levites originated as migrants and that the name Levites indicates their ''joining'' with either the Israelites in general or the earlier Israelite priesthood in particular.

UHMWPE
Ultra-high-molecular-weight polyethylene (UHMWPE, UHMW) is a subset of the thermoplastic polyethylene. Also known as high-modulus polyethylene, (HMPE), it has extremely long chains, with a molecular mass usually between 3.5 and 7.5 million amu. The longer chain serves to transfer load more effectively to the polymer backbone by strengthening intermolecular interactions. This results in a very tough material, with the highest impact strength of any thermoplastic presently made. UHMWPE is odorless, tasteless, and nontoxic. It embodies all the characteristics of high-density polyethylene (HDPE) with the added traits of being resistant to concentrated acids and alkalis, as well as numerous organic solvents. It is highly resistant to corrosive chemicals except oxidizing acids; has extremely low moisture absorption and a very low coefficient of friction; is self-lubricating (see boundary lubrication); and is highly resistant to abrasion, in some forms being 15 times more resistant to ...
