Burn Of Ayreland
The Burn of Ayreland (or Ireland) is a northwesterly flowing coastal stream on Mainland Orkney, Scotland, that discharges to the Clestrain Sound about two miles south of Stenness. Draining chiefly agricultural lands elevated mosses and moorland. This stream has a notable lack of turbidity and a pH level of approximately 8. Armouring of the stream bottom consists of pebbles, cobbles and occasional boulders. Prehistory and history This burn is located a few miles south of very significant Neolithic and Iron Age archaeological sites. A few miles to the north are the Standing Stones of Stenness and the Ring of Brodgar.J.

Burn Just South Of Maes Howe, Mainland Orkney - Geograph
A burn is an injury to skin, or other tissues, caused by heat, cold, electricity, chemicals, friction, or ultraviolet radiation (like sunburn). Most burns are due to heat from hot liquids (called scalding), solids, or fire. Burns occur mainly in the home or the workplace. In the home, risks are associated with domestic kitchens, including stoves, flames, and hot liquids. In the workplace, risks are associated with fire and chemical and electric burns. Alcoholism and smoking are other risk factors. Burns can also occur as a result of self-harm or violence between people (assault). Burns that affect only the superficial skin layers are known as superficial or first-degree burns. They appear red without blisters and pain typically lasts around three days. When the injury extends into some of the underlying skin layer, it is a partial-thickness or second-degree burn. Blisters are frequently present and they are often very painful. Healing can require up to eight weeks and scarri ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cobble (geology)
A cobble (sometimes a cobblestone) is a clast of rock defined on the Udden–Wentworth scale as having a particle size of , larger than a pebble and smaller than a boulder. Other scales define a cobble's size differently. A rock made predominantly of cobbles is termed a conglomerate. Cobblestone is a building material based on cobbles. Etymology Cobbles, also called cobblestones, derive their name from the word cob, meaning a rounded lump. The term is further related to the German ', meaning ''head''. Chester Wentworth referred to cobbles as ''cobble bowlders'' in his 1922 paper that would become the basis for the Udden–Wentworth scale. Classifications Within the widely used Krumbein phi scale of grain sizes, cobbles are defined as clasts of rock ranging from −6 to −8 φ. This classification corresponds with the Udden–Wentworth size scale which defines cobbles as clasts with diameters from . On this scale, cobbles are larger than pebbles which measure in diameter a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Waulkmill Bay
Waulkmill Bay is a tidal bay on the southwest of Mainland Orkney, Scotland. This bay and its immediately surrounding area have been identified as a Site of Special Scientific Interest by Scottish Natural Heritage. Immediately to the east of Waulkmill Bay is the RSPB site of Hobbister Preserve. The freshwater feed from the Loch of Kirbister and the presence of reformative sand bars make the sandy beach area at the north end of Waulkmill Bay a unique habitat for birds. The salt marsh area associated with Waulkmill Bay is a particularly noted avian habitat.

Maes Howe
Maeshowe (or Maes Howe; non, Orkhaugr) is a Neolithic chambered cairn and passage grave situated on Mainland Orkney, Scotland. It was probably built around . In the archaeology of Scotland, it gives its name to the Maeshowe type of chambered cairn, which is limited to Orkney. Maeshowe is a significant example of Neolithic craftsmanship and is, in the words of the archaeologist Stuart Piggott, "a superlative monument that by its originality of execution is lifted out of its class into a unique position." Maeshowe is a scheduled monument and is part of the "Heart of Neolithic Orkney", a group of sites including Skara Brae, which were designated a UNESCO World Heritage Site in 1999. Design and construction Maeshowe is one of the largest tombs in Orkney; the mound encasing the tomb is in diameter and rises to a height of Surrounding the mound, at a distance of to is a ditch up to wide. The grass mound hides a complex of passages and chambers built of carefully crafted slabs o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ring Of Brodgar
The Ring of Brodgar (or Brogar, or Ring o' Brodgar) is a Neolithic henge and stone circle about 6 miles north-east of Stromness on Mainland, the largest island in Orkney, Scotland. It is part of the UNESCO World Heritage Site known as the Heart of Neolithic Orkney. General information The Ring of Brodgar (or Brogar, or Ring o' Brodgar) is a Neolithic henge and stone circle in Mainland, Orkney, Scotland. It is the only major henge and stone circle in Britain which is an almost perfect circle. Most henges do not contain stone circles; Brodgar is a striking exception, ranking with Avebury and Stonehenge among the greatest of such sites. The ring of stones stands on a small isthmus between the Lochs of Stenness and Harray. These are the northernmost examples of circle henges in Britain. Unlike similar structures such as Avebury, there are no obvious stones inside the circle, but since the interior of the circle has never been excavated by archaeologists, the possibility remains th ...

Standing Stones Of Stenness
The Standing Stones of Stenness is a Neolithic monument five miles northeast of Stromness on the mainland of Orkney, Scotland. This may be the oldest henge site in the British Isles. Various traditions associated with the stones survived into the modern era and they form part of the Heart of Neolithic Orkney World Heritage Site. They are looked after by Historic Environment Scotland as a scheduled monument. Layout and location The surviving stones are sited on a promontory at the south bank of the stream that joins the southern ends of the sea loch Loch of Stenness and the freshwater Loch of Harray. The name, which is pronounced ''stane-is'' in Orcadian dialect, comes from Old Norse meaning ''stone headland''. The stream is now bridged, but at one time was crossed by a stepping stone causeway, and the Ring of Brodgar lies about away to the north-west, across the stream and near the tip of the isthmus formed between the two lochs. Maeshowe chambered cairn is about to the east ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Archaeological
Archaeology or archeology is the scientific study of human activity through the recovery and analysis of material culture. The archaeological record consists of artifacts, architecture, biofacts or ecofacts, sites, and cultural landscapes. Archaeology can be considered both a social science and a branch of the humanities. It is usually considered an independent academic discipline, but may also be classified as part of anthropology (in North America – the four-field approach), history or geography. Archaeologists study human prehistory and history, from the development of the first stone tools at Lomekwi in East Africa 3.3 million years ago up until recent decades. Archaeology is distinct from palaeontology, which is the study of fossil remains. Archaeology is particularly important for learning about prehistoric societies, for which, by definition, there are no written records. Prehistory includes over 99% of the human past, from the Paleolithic until the adven ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Iron Age
The Iron Age is the final epoch of the three-age division of the prehistory and protohistory of humanity. It was preceded by the Stone Age (Paleolithic, Mesolithic, Neolithic) and the Bronze Age (Chalcolithic). The concept has been mostly applied to Iron Age Europe and the Ancient Near East, but also, by analogy, to other parts of the Old World. The duration of the Iron Age varies depending on the region under consideration. It is defined by archaeological convention. The "Iron Age" begins locally when the production of iron or steel has advanced to the point where iron tools and weapons replace their bronze equivalents in common use. In the Ancient Near East, this transition took place in the wake of the Bronze Age collapse, in the 12th century BC. The technology soon spread throughout the Mediterranean Basin region and to South Asia (Iron Age in India) between the 12th and 11th century BC. Its further spread to Central Asia, Eastern Europe, and Central Europe is somewhat dela ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Neolithic
The Neolithic period, or New Stone Age, is an Old World archaeological period and the final division of the Stone Age. It saw the Neolithic Revolution, a wide-ranging set of developments that appear to have arisen independently in several parts of the world. This "Neolithic package" included the introduction of farming, domestication of animals, and change from a hunter-gatherer lifestyle to one of settlement. It began about 12,000 years ago when farming appeared in the Epipalaeolithic Near East, and later in other parts of the world. The Neolithic lasted in the Near East until the transitional period of the Chalcolithic (Copper Age) from about 6,500 years ago (4500 BC), marked by the development of metallurgy, leading up to the Bronze Age and Iron Age. In other places the Neolithic followed the Mesolithic (Middle Stone Age) and then lasted until later. In Ancient Egypt, the Neolithic lasted until the Protodynastic period, 3150 BC.Karin Sowada and Peter Grave. Egypt in th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Boulder
In geology, a boulder (or rarely bowlder) is a rock fragment with size greater than in diameter. Smaller pieces are called cobbles and pebbles. While a boulder may be small enough to move or roll manually, others are extremely massive. In common usage, a boulder is too large for a person to move. Smaller boulders are usually just called rocks or stones. The word ''boulder'' derives from ''boulder stone'', from the Middle English ''bulderston'' or Swedish ''bullersten''.

Pebble
A pebble is a clast of rock with a particle size of based on the Udden-Wentworth scale of sedimentology. Pebbles are generally considered larger than granules ( in diameter) and smaller than cobbles ( in diameter). A rock made predominantly of pebbles is termed a conglomerate. Pebble tools are among the earliest known man-made artifacts, dating from the Palaeolithic period of human history. A beach composed chiefly of surface pebbles is commonly termed a shingle beach. This type of beach has armoring characteristics with respect to wave erosion, as well as ecological niches that provide habitat for animals and plants. Inshore banks of shingle (large quantities of pebbles) exist in some locations, such as the entrance to the River Ore, England, where the moving banks of shingle give notable navigational challenges. Pebbles come in various colors and textures and can have streaks, known as veins, of quartz or other minerals. Pebbles are mostly smooth but, dependent on ...
