Corlea Trackway
__NOTOC__ The Corlea Trackway () is an Iron Age trackway, or ''togher'', near the village of Keenagh, south of Longford, County Longford, in Ireland. It was known locally as the ''Danes' Road''. It was constructed from oak planks in 148–147 BC, making it contemporary with the Siege of Carthage. The trackway is situated in an area which is the site of industrial-scale mechanised peat harvesting by the Bord na Móna, principally to supply the peat-fired power stations of the Electricity Supply Board. While today a generally flat and open landscape, in the Iron Age it was covered by bog, quicksand, and ponds, surround by dense woodlands of birch, willow, hazel and alder while higher ground was covered by oak and ash. The terrain was dangerous and impassible for much of the year.Raftery, ''Pagan Celtic Ireland'', chapter 5. In 1984, timbers recovered from Corlea were radiocarbon dated to the Iron Age, rather than the Bronze Age as had been expected, and an archaeological pro ...

Keenagh, County Longford
Keenagh or Kenagh () is a village in County Longford, Ireland. It is situated on the R397 road (Ireland), R397 near the Royal Canal of Ireland, Royal Canal. A small village with two churches, (Catholic and Church of Ireland), a couple of shops and three pubs, it lies south of Longford, Longford Town. There are also GAA and soccer clubs in the village, as well as a community centre. Corlea Trackway is an Iron Age trackway near the village. The Newcomen Baronets were the local landowners for several generations. In the period 2000 to 2007 many new houses were built around Keenagh, due to the tax incentives available in the area and without direct consideration to demand. As of 2010, many were vacant or incomplete constituting ghost estates. Between the 2002 and 2016 census, the population of Keenagh more than doubled from 225 to 581 inhabitants.

Willow
Willows, also called sallows and osiers, from the genus ''Salix'', comprise around 400 speciesMabberley, D.J. 1997. The Plant Book, Cambridge University Press #2: Cambridge. of typically deciduous trees and shrubs, found primarily on moist soils in cold and temperate regions. Most species are known as willow, but some narrow-leaved shrub species are called osier, and some broader-leaved species are referred to as sallow (from Old English ''sealh'', related to the Latin word ''salix'', willow). Some willows (particularly arctic and alpine species) are low-growing or creeping shrubs; for example, the dwarf willow (''Salix herbacea'') rarely exceeds in height, though it spreads widely across the ground. Description Willows all have abundant watery bark sap, which is heavily charged with salicylic acid, soft, usually pliant, tough wood, slender branches, and large, fibrous, often stoloniferous roots. The roots are remarkable for their toughness, size, and tenacity to live ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tumulus
A tumulus (plural tumuli) is a mound of earth and stones raised over a grave or graves. Tumuli are also known as barrows, burial mounds or ''kurgans'', and may be found throughout much of the world. A cairn, which is a mound of stones built for various purposes, may also originally have been a tumulus. Tumuli are often categorised according to their external apparent shape. In this respect, a long barrow is a long tumulus, usually constructed on top of several burials, such as passage graves. A round barrow is a round tumulus, also commonly constructed on top of burials. The internal structure and architecture of both long and round barrows has a broad range; the categorization only refers to the external apparent shape. The method of may involve a dolmen, a cist, a mortuary enclosure, a mortuary house, or a chamber tomb. Examples of barrows include Duggleby Howe and Maeshowe. Etymology The word ''tumulus'' is Latin for 'mound' or 'small hill', which is derived from th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dendrochronological
Dendrochronology (or tree-ring dating) is the scientific method of dating tree rings (also called growth rings) to the exact year they were formed. As well as dating them, this can give data for dendroclimatology, the study of climate and atmospheric conditions during different periods in history from wood. Dendrochronology derives from Ancient Greek (), meaning "tree", (), meaning "time", and (), "the study of". Dendrochronology is useful for determining the precise age of samples, especially those that are too recent for radiocarbon dating, which always produces a range rather than an exact date. However, for a precise date of the death of the tree a full sample to the edge is needed, which most trimmed timber will not provide. It also gives data on the timing of events and rates of change in the environment (most prominently climate) and also in wood found in archaeology or works of art and architecture, such as old panel paintings. It is also used as a check in radiocar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Corduroy Road
A corduroy road or log road is a type of road or timber trackway made by placing logs, perpendicular to the direction of the road over a low or swampy area. The result is an improvement over impassable mud or dirt roads, yet rough in the best of conditions and a hazard to horses due to shifting loose logs. Corduroy roads can also be built as a foundation for other surfacing. If the logs are buried in wet, acidic, anaerobic soils such as peat or muskeg, they decay very slowly. A few corduroy road foundations that date back to the early 20th century still exist in North America. One example is the Alaska Highway between Burwash Landing and Koidern, Yukon, Canada, which was rebuilt in 1943, less than a year after the original route was graded on thin soil and vegetation over permafrost, by using corduroy, then building a gravel road on top. During the 1980s, the gravel was covered with a chip-seal. The late 1990s saw replacement of this road with modern road construction, ...

Hurdle
A hurdle (UK English, limited US English) is a moveable section of light fence. In the United States, terms such as "panel", "pipe panel" or simply "fence section" are used to describe moveable sections of fencing intended for agricultural use and crowd control; "hurdle" refers primarily to fences used as jumping obstacles for steeplechasing with horses or human track and field competition. Traditional hurdles were made from wattle, but modern designs for fencing are often made of metal. They are used for handling livestock, as decorative fencing, for steeplechasing and in the track and field event of hurdling and Shuttle Hurdle Relay. Types Traditional hurdles are made from wattle, usually of hazel or willow. Hurdle-making is a traditional woodland craft, made by placing upright sticks in holes in a log and weaving split branches between them. Historically they were used to pen livestock or to separate land in open field systems, but they are now popular as decorative fen ...

Bronze Age
The Bronze Age is a historic period, lasting approximately from 3300 BC to 1200 BC, characterized by the use of bronze, the presence of writing in some areas, and other early features of urban civilization. The Bronze Age is the second principal period of the three-age system proposed in 1836 by Christian Jürgensen Thomsen for classifying and studying ancient societies and history. An ancient civilization is deemed to be part of the Bronze Age because it either produced bronze by smelting its own copper and alloying it with tin, arsenic, or other metals, or traded other items for bronze from production areas elsewhere. Bronze is harder and more durable than the other metals available at the time, allowing Bronze Age civilizations to gain a technological advantage. While terrestrial iron is naturally abundant, the higher temperature required for smelting, , in addition to the greater difficulty of working with the metal, placed it out of reach of common use until the end o ...

Radiocarbon Date
Radiocarbon dating (also referred to as carbon dating or carbon-14 dating) is a method for determining the age of an object containing organic material by using the properties of radiocarbon, a radioactive isotope of carbon. The method was developed in the late 1940s at the University of Chicago by Willard Libby. It is based on the fact that radiocarbon () is constantly being created in the Earth's atmosphere by the interaction of cosmic rays with atmospheric nitrogen. The resulting combines with atmospheric oxygen to form radioactive carbon dioxide, which is incorporated into plants by photosynthesis; animals then acquire by eating the plants. When the animal or plant dies, it stops exchanging carbon with its environment, and thereafter the amount of it contains begins to decrease as the undergoes radioactive decay. Measuring the amount of in a sample from a dead plant or animal, such as a piece of wood or a fragment of bone, provides information that can be used to calcu ...
