Sled
A sled, skid, sledge, or sleigh is a land vehicle that slides across a surface, usually of ice or snow. It is built with either a smooth underside or a separate body supported by two or more smooth, relatively narrow, longitudinal runners similar in principle to skis. This reduces the amount of friction, which helps to carry heavy loads. Some designs are used to transport passengers or cargo across relatively level ground. Others are designed to go downhill for recreation, particularly by children, or competition. (Compare cross-country skiing with its downhill cousin.) Shades of meaning differentiating the three terms often reflect regional variations depending on historical uses and prevailing climate. In British English, ''sledge'' is the general term, and more common than ''sled''. ''Toboggan'' is sometimes used synonymously with ''sledge'' but more often to refer to a particular type of sledge without runners. ''Sleigh'' refers to a moderate to large-sized, usually ...

Toboggan
A toboggan is a simple sled traditionally used by children. It is also a traditional form of transport used by the Innu and Cree of northern Canada. In modern times, it is used on snow to carry one or more people (often children) down a hill or other slope for recreation. Designs vary from simple, traditional models to modern engineered composites. A toboggan differs from most sleds or sleighs in that it has no runners or skis (or only low ones) on the underside. The bottom of a toboggan rides directly on the snow. Some parks include designated toboggan hills where ordinary sleds are not allowed and which may include toboggan runs similar to bobsleigh courses. Toboggans can vary depending on the climate and geographical region. Such examples are Tangalooma (Australia) where toboggans are made from Masonite boards and used for travelling down steep sand dunes at speeds up to . Design and use Before white colonists arrived in America, toboggan was a Native Indian term fo ...

Reindeer
Reindeer (in North American English, known as caribou if wild and ''reindeer'' if domesticated) are deer in the genus ''Rangifer''. For the last few decades, reindeer were assigned to one species, ''Rangifer tarandus'', with about 10 subspecies. A 2022 revision of the genus elevated five of the subspecies to species (see Taxonomy below). They have a circumpolar distribution and are native to the Arctic, sub-Arctic, tundra, boreal forest, and mountainous regions of northern Europe, Siberia, and North America. Reindeer occur in both migratory and sedentary populations, and their herd sizes vary greatly in different regions. The tundra subspecies are adapted for extreme cold, and some are adapted for long-distance migration. Reindeer vary greatly in size and color from the smallest species, the Svalbard reindeer (''R. t. platyrhynchus''), to the largest subspecies, Osborn's caribou (''R. t. osborni''). Although reindeer are quite numerous, some species and subspecies are in d ...

Vozok
Vozok (возок) is a type of closed winter sled that was used throughout Russia until the late 19th century. With the aim of reducing heat loss, the vozok usually had very small windows and sometimes a furnace to keep it warm. Inside it was quite dark. Vozoks provided a high-speed means of transport through the snow-covered plains of European Russia and Siberia. It was a means of transport preferred by royals, bishops, and boyars of Muscovy. One patriarch is known to have used covered sleds even in summertime. A miniature vozok of Tsarevich Peter and several other royal sleds of historical importance have been preserved in the Kremlin Armoury The Kremlin Armoury,Officially called the "Armou/ory Chamber" but also known as the cannon yard, the "Armou/ory Palace", the "Moscow Armou/ory", the "Armou/ory Museum", and the "Moscow Armou/ory Museum" but different from the Kremlin Arsenal.

Land Vehicle
A vehicle (from la, vehiculum) is a machine that transports people or cargo. Vehicles include wagons, bicycles, motor vehicles (motorcycles, cars, trucks, buses, mobility scooters for disabled people), railed vehicles (trains, trams), watercraft (ships, boats, underwater vehicles), amphibious vehicles (screw-propelled vehicles, hovercraft), aircraft (airplanes, helicopters, aerostats) and spacecraft.Halsey, William D. (Editorial Director): ''MacMillan Contemporary Dictionary'', page 1106. MacMillan Publishing, 1979. Land vehicles are classified broadly by what is used to apply steering and drive forces against the ground: wheeled, tracked, railed or skied. ISO 3833-1977 is the standard, also internationally used in legislation, for road vehicles types, terms and definitions. History * The oldest boats found by archaeological excavation are logboats, with the oldest logboat found, the Pesse canoe found in a bog in the Netherlands, being carbon dated to 8040 - ...

Obelisk
An obelisk (; from grc, ὀβελίσκος ; diminutive of ''obelos'', " spit, nail, pointed pillar") is a tall, four-sided, narrow tapering monument which ends in a pyramid-like shape or pyramidion at the top. Originally constructed by Ancient Egyptians and called ''tekhenu'', the Greeks used the Greek term to describe them, and this word passed into Latin and ultimately English. Ancient obelisks are monolithic; they consist of a single stone. Most modern obelisks are made of several stones. Ancient obelisks Egyptian Obelisks were prominent in the architecture of the ancient Egyptians, and played a vital role in their religion placing them in pairs at the entrance of the temples. The word "obelisk" as used in English today is of Greek rather than Egyptian origin because Herodotus, the Greek traveler, was one of the first classical writers to describe the objects. A number of ancient Egyptian obelisks are known to have survived, plus the " Unfinished Obelisk" found part ...

Friction
Friction is the force resisting the relative motion of solid surfaces, fluid layers, and material elements sliding against each other. There are several types of friction: *Dry friction is a force that opposes the relative lateral motion of two solid surfaces in contact. Dry friction is subdivided into ''static friction'' ("stiction") between non-moving surfaces, and ''kinetic friction'' between moving surfaces. With the exception of atomic or molecular friction, dry friction generally arises from the interaction of surface features, known as asperities (see Figure 1). *Fluid friction describes the friction between layers of a viscous fluid that are moving relative to each other. *Lubricated friction is a case of fluid friction where a lubricant fluid separates two solid surfaces. *Skin friction is a component of drag, the force resisting the motion of a fluid across the surface of a body. *Internal friction is the force resisting motion between the elements making up a so ...

The Washington Post
''The Washington Post'' (also known as the ''Post'' and, informally, ''WaPo'') is an American daily newspaper published in Washington, D.C. It is the most widely circulated newspaper within the Washington metropolitan area and has a large national audience. Daily broadsheet editions are printed for D.C., Maryland, and Virginia. The ''Post'' was founded in 1877. In its early years, it went through several owners and struggled both financially and editorially. Financier Eugene Meyer purchased it out of bankruptcy in 1933 and revived its health and reputation, work continued by his successors Katharine and Phil Graham (Meyer's daughter and son-in-law), who bought out several rival publications. The ''Post'' 1971 printing of the Pentagon Papers helped spur opposition to the Vietnam War. Subsequently, in the best-known episode in the newspaper's history, reporters Bob Woodward and Carl Bernstein led the American press's investigation into what became known as the Watergate scandal ...

Oxen
An ox ( : oxen, ), also known as a bullock (in BrE British English (BrE, en-GB, or BE) is, according to Oxford Dictionaries, "English as used in Great Britain, as distinct from that used elsewhere". More narrowly, it can refer specifically to the English language in England, or, more broadly, ..., AusE, and IndE), is a male bovine trained and used as a draft animal. Oxen are commonly castration, castrated adult male cattle; castration inhibits testosterone and aggression, which makes the males docile and safer to work with. Cows (adult females) or bulls (intact males) may also be used in some areas. Oxen are used for Plough, plowing, for transport (pulling carts, hauling wagons and even riding), for threshing grain by trampling, and for powering machines that grind grain or supply irrigation among other purposes. Oxen may be also used to skidder, skid logs in forests, particularly in low-impact, select-cut logging. Oxen are usually yoked in pairs. Light work such a ...

Uphill Sleigh Ride
Uphill is a village in the civil parish of Weston-super-Mare in North Somerset, England, at the southern edge of the town, on the Bristol Channel coast. History Bone and stone tools found in caves at Uphill provide evidence of human activity in the Upper Palaeolithic period, and a radiocarbon date of around 28,000 Before Present, which came from a bone point, was the first scientifically derived direct date from the entire British Isles for an artefact of that period (the Aurignacian). The River Axe enters the Bristol Channel at Uphill where it is sheltered by Brean Down and it is possible that there was a port at Uphill in Roman times but no archaeological evidence has been found for this.Crockford-Hawley (2004) surmises that while ''archaeological evidence has yet to prove portexisted, most local people are quite happy to rely on long-established hearsay!'' Leach (2001) does not claim that there was a port at Uphill in the Romano-British period but does write that ''rivers s ...
