Crug Hywel
Crug Hywel is an Iron Age Celtic hillfort, with a clearly visible earth and stone ditch and rampart. Crug Hywel is approached by a couple of public footpaths across farmland from Crickhowell and Llanbedr and visited by the Beacons Way. It lies within an area designated as open country over which the public have the right to roam. The name is sometimes given to the flat-topped hill itself, which is also called Table Mountain in English). Located at the southern edge of the Black Mountains in south-east Wales, it rises to 451 m above sea level, from the southern flank of Pen Cerrig-calch (701 m), and overlooks the town of Crickhowell, whose name derives from Crug Hywel. The Welsh name Mynydd y Begwn is also used of this summit. As a result, it has been suggested that the name Crug Hywel (which means 'Hywel's mound') may originally have referred to the castle mound in Crickhowell.

Welsh Language
Welsh ( or ) is a Celtic language family, Celtic language of the Brittonic languages, Brittonic subgroup that is native to the Welsh people. Welsh is spoken natively in Wales, by some in England, and in Y Wladfa (the Welsh colony in Chubut Province, Argentina). Historically, it has also been known in English as "British", "Cambrian", "Cambric" and "Cymric". The Welsh Language (Wales) Measure 2011 gave the Welsh language official status in Wales. Both the Welsh and English languages are ''de jure'' official languages of the Welsh Parliament, the Senedd. According to the 2021 United Kingdom census, 2021 census, the Welsh-speaking population of Wales aged three or older was 17.8% (538,300 people) and nearly three quarters of the population in Wales said they had no Welsh language skills. Other estimates suggest that 29.7% (899,500) of people aged three or older in Wales could speak Welsh in June 2022. Almost half of all Welsh speakers consider themselves fluent Welsh speakers ...

Brecon Beacons National Park
The Brecon Beacons National Park ( cy, Parc Cenedlaethol Bannau Brycheiniog) is one of three national parks in Wales, and is centred on the Brecon Beacons range of hills in southern Wales. It includes the Black Mountain (range), Black Mountain ( cy, Y Mynydd Du) in the west, Fforest Fawr (translates as 'great forest') and the Brecon Beacons in the centre and the Black Mountains, Wales, Black Mountains ( cy, Y Mynydd Du or Mynyddoedd Duon) in the east. Description The Brecon Beacons National Park was established in 1957, the last of the three Welsh parks designated after Snowdonia in 1951 and the Pembrokeshire Coast in 1952. It stretches from Llandeilo in the west to Hay-on-Wye in the northeast and Pontypool in the southeast, covering and encompassing four main regions – the Black Mountain (range), Black Mountain in the west, reaching 802 metres (2631 feet) at Fan Brycheiniog, Fforest Fawr and the Brecon Beacons in the centre, including the highest summit in the park and in ...

Archaeological Sites In The Brecon Beacons National Park
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 advent of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mountains And Hills Of Powys
A mountain is an elevated portion of the Earth's crust, generally with steep sides that show significant exposed bedrock. Although definitions vary, a mountain may differ from a plateau in having a limited summit area, and is usually higher than a hill, typically rising at least 300 metres (1,000 feet) above the surrounding land. A few mountains are isolated summits, but most occur in mountain ranges. Mountains are formed through tectonic forces, erosion, or volcanism, which act on time scales of up to tens of millions of years. Once mountain building ceases, mountains are slowly leveled through the action of weathering, through slumping and other forms of mass wasting, as well as through erosion by rivers and glaciers. High elevations on mountains produce colder climates than at sea level at similar latitude. These colder climates strongly affect the ecosystems of mountains: different elevations have different plants and animals. Because of the less hospitable terrain and ...

Hillforts In Powys
A hillfort is a type of earthwork used as a fortified refuge or defended settlement, located to exploit a rise in elevation for defensive advantage. They are typically European and of the Bronze Age or Iron Age. Some were used in the post-Roman period. The fortification usually follows the contours of a hill and consists of one or more lines of earthworks, with stockades or defensive walls, and external ditches. Hillforts developed in the Late Bronze and Early Iron Age, roughly the start of the first millennium BC, and were used in many Celtic areas of central and western Europe until the Roman conquest. Nomenclature The spellings "hill fort", "hill-fort" and "hillfort" are all used in the archaeological literature. The ''Monument Type Thesaurus'' published by the Forum on Information Standards in Heritage lists ''hillfort'' as the preferred term. They all refer to an elevated site with one or more ramparts made of earth, stone and/or wood, with an external ditch. Many ...

Landslide
Landslides, also known as landslips, are several forms of mass wasting that may include a wide range of ground movements, such as rockfalls, deep-seated grade (slope), slope failures, mudflows, and debris flows. Landslides occur in a variety of environments, characterized by either steep or gentle slope gradients, from mountain ranges to coastal cliffs or even underwater, in which case they are called submarine landslides. Gravity is the primary driving force for a landslide to occur, but there are other factors affecting slope stability that produce specific conditions that make a slope prone to failure. In many cases, the landslide is triggered by a specific event (such as a heavy rainfall, an earthquake, a slope cut to build a road, and many others), although this is not always identifiable. Causes Landslides occur when the slope (or a portion of it) undergoes some processes that change its condition from stable to unstable. This is essentially due to a decrease in the She ...

Period (geology)
The geologic time scale, or geological time scale, (GTS) is a representation of time based on the rock record of Earth. It is a system of chronological dating that uses chronostratigraphy (the process of relating strata to time) and geochronology (scientific branch of geology that aims to determine the age of rocks). It is used primarily by Earth scientists (including geologists, paleontologists, geophysicists, geochemists, and paleoclimatologists) to describe the timing and relationships of events in geologic history. The time scale has been developed through the study of rock layers and the observation of their relationships and identifying features such as lithologies, paleomagnetic properties, and fossils. The definition of standardized international units of geologic time is the responsibility of the International Commission on Stratigraphy (ICS), a constituent body of the International Union of Geological Sciences (IUGS), whose primary objective is to precisely define ...

Devonian
The Devonian ( ) is a geologic period and system of the Paleozoic era, spanning 60.3 million years from the end of the Silurian, million years ago (Mya), to the beginning of the Carboniferous, Mya. It is named after Devon, England, where rocks from this period were first studied. The first significant adaptive radiation of life on dry land occurred during the Devonian. Free-sporing vascular plants began to spread across dry land, forming extensive forests which covered the continents. By the middle of the Devonian, several groups of plants had evolved leaves and true roots, and by the end of the period the first seed-bearing plants appeared. The arthropod groups of myriapods, arachnids and hexapods also became well-established early in this period, after starting their expansion to land at least from the Ordovician period. Fish reached substantial diversity during this time, leading the Devonian to often be dubbed the Age of Fishes. The placoderms began dominating ...

Old Red Sandstone
The Old Red Sandstone is an assemblage of rocks in the North Atlantic region largely of Devonian age. It extends in the east across Great Britain, Ireland and Norway, and in the west along the northeastern seaboard of North America. It also extends northwards into Greenland and Svalbard. These areas were a part of the ancient continent of Euramerica, Euramerica/Laurussia. In Britain it is a lithostratigraphy, lithostratigraphic unit (a sequence of rock strata) to which Stratigraphy, stratigraphers accord Geological unit#Lithostratigraphic units, supergroup status and which is of considerable importance to early paleontology. For convenience the short version of the term, ORS is often used in literature on the subject. The term was coined to distinguish the sequence from the younger New Red Sandstone which also occurs widely throughout Britain. Sedimentology The Old Red Sandstone describes a suite of sedimentary rocks deposited in a variety of environments during the Devonian ...
