Fair Head is considered one of the best traditional climbing and bouldering locations in the British Isles, and is one of the biggest expanses of climbable rock in Northwest Europe. It has one of the largest concentration of extreme-graded routes in the British Isles, and has climbs at E9-grade (e.g. Rathlin Effect ), as well as highball problems at E9-grade (e.g. Long runs

With a writing system , Ogham , dating back to at least the 4th century AD, which was gradually replaced by Latin script since the 5th century AD, Irish has one of the oldest vernacular literatures in Western Europe . On the island, the language has three major dialects: Connacht , Munster and Ulster Irish . All three have distinctions in their speech and orthography . There

Irish became an official language of the EU on 1 January 2007, meaning that MEPs with Irish fluency can now speak the language in the European Parliament and at committees, although in the case of the latter they have to give prior notice to a simultaneous interpreter in order to ensure that what they say can be interpreted into other languages. While an official language of

The Strategy was produced on 21 December 2010 and will stay in action until 2030; it aims to target language vitality and revitalization of the Irish language. The 30-page document published by the Government of Ireland details the objectives it plans to work towards in an attempt to preserve and promote both the Irish language and the Gaeltacht. It
665-475: A concave upwards form, where the maximum inclination corresponds to the angle of repose of the mean debris particle size. Scree slopes are often assumed to be close to the angle of repose. This is the slope at which a pile of granular material becomes mechanically unstable. However, careful examination of scree slopes shows that only those that are either rapidly accumulating new material, or are experiencing rapid removal of material from their bases, are close to

These dolerite boulders have fallen off the cliffs above and the general required style is described as "steep, crimpy and powerful", with a caution that excess bouldering mats are needed to handle the poor landing areas due to
855-478: A cultural and social force. Irish speakers often insisted on using the language in law courts (even when they knew English), and Irish was also common in commercial transactions. The language was heavily implicated in the "devotional revolution" which marked the standardisation of Catholic religious practice and was also widely used in a political context. Down to the time of the Great Famine and even afterwards,

Before Irish became an official language it was afforded the status of treaty language and only the highest-level documents of the EU were made available in Irish. The Irish language was carried abroad in the modern period by a vast diaspora , chiefly to Great Britain and North America, but also to Australia , New Zealand and Argentina . The first large movements began in

An Irish translation of the Old Testament by Leinsterman Muircheartach Ó Cíonga , commissioned by Bishop Bedell , was published after 1685 along with a translation of the New Testament. Otherwise, Anglicisation was seen as synonymous with 'civilising' the native Irish. Currently, modern day Irish speakers in the church are pushing for language revival. It has been estimated that there were around 800,000 monoglot Irish speakers in 1800, which dropped to 320,000 by
1520-547: A result of linguistic imperialism . Today, Irish is still commonly spoken as a first language in Ireland's Gaeltacht regions, in which 2% of Ireland's population lived in 2022. The total number of people (aged 3 and over) in Ireland who declared they could speak Irish in April 2022 was 1,873,997, representing 40% of respondents, but of these, 472,887 said they never spoke it and a further 551,993 said they only spoke it within
1615-508: A slope, while talus is used more narrowly for material that accumulates at the base of a cliff or other rocky slope from which it has obviously eroded. Scree is formed by rockfall, which distinguishes it from colluvium . Colluvium is rock fragments or soil deposited by rainwash , sheetwash , or slow downhill creep , usually at the base of gentle slopes or hillsides. However, the terms scree , talus , and sometimes colluvium tend to be used interchangeably. The term talus deposit

It is loosely synonymous with talus , material that accumulates at the base of a projecting mass of rock, or talus slope , a landform composed of talus. The term scree is sometimes used more broadly for any sheet of loose rock fragments mantling

By 2022, the number of such speakers had fallen to 71,968. Before the partition of Ireland in 1921, Irish was recognised as a school subject and as "Celtic" in some third level institutions. Between 1921 and 1972, Northern Ireland had devolved government. During those years
2280-455: Is generally good sorting of sediment by size: larger particles accumulate more rapidly at the bottom of the slope. Cementation occurs as fine-grained material fills in gaps between debris. The speed of consolidation depends on the composition of the slope; clayey components will bind debris together faster than sandy ones. Should weathering outpace the supply of sediment, plants may take root. Plant roots diminish cohesive forces between

According to data compiled by the Department of Tourism, Culture, Arts, Gaeltacht , Sport and Media , only 1/4 of households in Gaeltacht areas are fluent in Irish. The author of a detailed analysis of the survey, Donncha Ó hÉallaithe of the Galway-Mayo Institute of Technology , described
2565-462: Is sometimes used to distinguish the landform from the material of which it is made. The exact definition of scree in the primary literature is somewhat relaxed, and it often overlaps with both talus and colluvium . The term scree comes from the Old Norse term for landslide , skriða , while the term talus is a French word meaning a slope or embankment. Talus deposits typically have
2660-508: Is still a possibility of the deposit slopes themselves failing. If the talus deposit pile shifts and the particles exceed the angle of repose, the scree itself may slide and fail. Phenomena such as acid rain may also contribute to the chemical degradation of rocks and produce more loose sediments. Biotic processes often intersect with both physical and chemical weathering regimes, as the organisms that interact with rocks can mechanically or chemically alter them. Lichen frequently grow on

The efficiency of freeze-thaw processes in scree production is a subject of ongoing debate. Many researchers believe that ice formation in large open fracture systems cannot generate high enough pressures to force the fracturing apart of parent rocks, and instead suggest that
3135-666: The Fíor-Ghaeltacht (true Gaeltacht ), a term originally officially applied to areas where over 50% of the population spoke Irish. There are Gaeltacht regions in the following counties: Gweedore ( Gaoth Dobhair ), County Donegal, is the largest Gaeltacht parish in Ireland. Irish language summer colleges in the Gaeltacht are attended by tens of thousands of teenagers annually.

For a number of years there has been vigorous debate in political, academic and other circles about the failure of most students in English-medium schools to achieve competence in Irish, even after fourteen years of teaching as one of the three main subjects. The concomitant decline in the number of traditional native speakers has also been a cause of great concern. In 2007, filmmaker Manchán Magan found few Irish speakers in Dublin , and faced incredulity when trying to get by speaking only Irish in Dublin. He

4465-443: The coarse and fine components, degrading the slope. The predominant processes that degrade a rock slope depend largely on the regional climate (see below), but also on the thermal and topographic stresses governing the parent rock material. Example process domains include: Scree formation is commonly attributed to the formation of ice within mountain rock slopes. The presence of joints , fractures , and other heterogeneities in

Despite the thickness, the heat from the Fair Head sill did not alter the underlying Triassic sandstone , however, shales have been converted to hornfels extending up to 5 metres (16 ft) from
6935-655: The number now is between 20,000 and 30,000." In the 1920s, when the Irish Free State was founded, Irish was still a vernacular in some western coastal areas. In the 1930s, areas where more than 25% of the population spoke Irish were classified as Gaeltacht . Today, the strongest Gaeltacht areas, numerically and socially, are those of South Connemara , the west of the Dingle Peninsula , and northwest Donegal, where many residents still use Irish as their primary language. These areas are often referred to as
7030-503: The other official language, if not already passed in both official languages. In November 2016, RTÉ reported that over 2.3 million people worldwide were learning Irish through the Duolingo app. Irish president Michael D. Higgins officially honoured several volunteer translators for developing the Irish edition, and said the push for Irish language rights remains an "unfinished project". There are rural areas of Ireland where Irish
7125-557: The political party holding power in the Stormont Parliament , the Ulster Unionist Party (UUP), was hostile to the language. The context of this hostility was the use of the language by nationalists. In broadcasting, there was an exclusion on the reporting of minority cultural issues, and Irish was excluded from radio and television for almost the first fifty years of the previous devolved government. After
7220-603: The register of Antrim ASSI . Fair Head is a sill of Palaeogene age that is the thickest and most extensive of the various sills from the plateau lavas of northeast Ireland. A sill is a tabular body of what was once molten rock that was injected into horizontal rocks (usually well-bedded sedimentary strata). Fair Head's sill is 85 metres (279 ft) thick at its maximum, and consists of columnar-jointed dolerite rock (a medium-grained igneous rock compositionally equivalent to finer-grained basalt ) showing crystals of olivine , that intruded into Carboniferous sediments in
7315-492: The relationship between the three Goidelic languages (Irish, Scottish Gaelic and Manx). Gaelic is a collective term for the Goidelic languages, and when the context is clear it may be used without qualification to refer to each language individually. When the context is specific but unclear, the term may be qualified, as Irish Gaelic, Scottish Gaelic or Manx Gaelic. Historically the name "Erse" ( / ɜːr s / URS )
7410-432: The requirement for entrance to the public service was changed to proficiency in just one official language. Nevertheless, Irish remains a required subject of study in all schools in the Republic of Ireland that receive public money (see Education in the Republic of Ireland ). Teachers in primary schools must also pass a compulsory examination called Scrúdú Cáilíochta sa Ghaeilge . As of 2005, Garda Síochána recruits need
7505-546: The requirement for long and intimidating abseils for access in many areas, and the high concentration of E-grade climbs, means that it is ideally a crag for intermediate and even more for expert-level climbers. There have been fatalities at the crag. An annual Fair Head Climbing Meet is held over the first weekend of June for all climbers. The cliffs abound in well-protected steep crack climbing, between one and four pitches in length, with routes that range from under 20 metres (66 ft) to over 100 metres (330 ft). Many of
7600-647: The revival was the Gaelic League ( Conradh na Gaeilge ), and particular emphasis was placed on the folk tradition, which in Irish is particularly rich. Efforts were also made to develop journalism and a modern literature. Although it has been noted that the Catholic Church played a role in the decline of the Irish language before the Gaelic Revival, the Protestant Church of Ireland also made only minor efforts to encourage use of Irish in
7695-414: The road above the cliff, a human-made Iron Age island or crannóg can be seen in the middle of a lake, Lough na Cranagh. The lakes are stocked with trout and can be fished during the summer months. All of the land at Fair Head is private farmland, and not owned by the National Trust (who only have a lease on the land to the east of the headland). Access is by the goodwill of local farm owners. Fair Head
7790-543: The rock wall can allow precipitation , groundwater , and surface runoff to flow through the rock. If the temperature drops below the freezing point of the fluid contained within the rock, during particularly cold evenings, for example, this water can freeze. Since water expands by 9% when it freezes, it can generate large forces that either create new cracks or wedge blocks into an unstable position. Special boundary conditions (rapid freezing and water confinement) may be required for this to happen. Freeze-thaw scree production
7885-506: The substrate into unconsolidated sediments. Scree often collects at the base of glaciers , concealing them from their environment. For example, Lech dl Dragon , in the Sella group of the Dolomites , is derived from the melting waters of a glacier and is hidden under a thick layer of scree. Debris cover on a glacier affects the energy balance and, therefore, the melting process. Whether
7980-475: The surface by thin, permeable sheets of sediment, screes experience cold air seepage from the bottom of the slope where sediment is thinnest. This freezing circulating air maintains internal scree temperatures 6.8-9.0 °C colder than external scree temperatures. These <0 °C thermal anomalies occur up to 1000m below sites with mean annual air temperatures of 0 °C. Patchy permafrost , which forms under conditions <0 °C, probably exists at
8075-421: The surface of, or within, rocks. Particularly during the initial colonization process, the lichen often inserts its hyphae into small fractures or mineral cleavage planes that exist in the host rock. As the lichen grows, the hyphae expand and force the fractures to widen. This increases the potential of fragmentation, possibly leading to rockfalls. During the growth of the lichen thallus , small fragments of
8170-599: The top of the crag. Fair Head's eastern end (the Small Crag , and the Murlough Bay bouldering area) can be approached from the Murlough Bay car park. The two main descent options to the base of the crag by foot are the popular Ballycastle Descent Gully , and the less popular Grey Man's Path Gully . Walking along the base of the Fair Head crag for any distance is not recommended as the terrain makes it time-consuming and very unpleasant, and therefore for routes in
8265-726: The vacancy to which they are appointed. This requirement is laid down by the University College Galway Act, 1929 (Section 3). In 2016, the university faced controversy when it announced the planned appointment of a president who did not speak Irish. Misneach staged protests against this decision. The following year the university announced that Ciarán Ó hÓgartaigh , a fluent Irish speaker, would be its 13th president. He assumed office in January 2018; in June 2024, he announced he would be stepping down as president at
8360-452: The water and ice simply flow out of the fractures as pressure builds. Many argue that frost heaving , like that known to act in soil in permafrost areas, may play an important role in cliff degradation in cold places. Eventually, a rock slope may be completely covered by its own scree, so that production of new material ceases. The slope is then said to be "mantled" with debris. However, since these deposits are still unconsolidated, there
8455-594: The work of such writers as Geoffrey Keating , is said to date from the 17th century, and was the medium of popular literature from that time on. From the 18th century on, the language lost ground in the east of the country. The reasons behind this shift were complex but came down to a number of factors: The change was characterised by diglossia (two languages being used by the same community in different social and economic situations) and transitional bilingualism (monoglot Irish-speaking grandparents with bilingual children and monoglot English-speaking grandchildren). By
8550-531: Was also sometimes used in Scots and then in English to refer to Irish; as well as Scottish Gaelic. Written Irish is first attested in Ogham inscriptions from the 4th century AD, a stage of the language known as Primitive Irish . These writings have been found throughout Ireland and the west coast of Great Britain. Primitive Irish underwent a change into Old Irish through the 5th century. Old Irish, dating from
8645-668: Was enacted 1 July 2019 and is an 18-page document that adheres to the guidelines of the Official Languages Act 2003 . The purpose of the Scheme is to provide services through the mediums of Irish and/or English. According to the Department of the Taoiseach, it is meant to "develop a sustainable economy and a successful society, to pursue Ireland's interests abroad, to implement the Government's Programme and to build
8740-495: Was establishing itself as the primary language. Irish speakers had first arrived in Australia in the late 18th century as convicts and soldiers, and many Irish-speaking settlers followed, particularly in the 1860s. New Zealand also received some of this influx. Argentina was the only non-English-speaking country to receive large numbers of Irish emigrants, and there were few Irish speakers among them. Scree The term scree
8835-474: Was passed 14 July 2003 with the main purpose of improving the number and quality of public services delivered in Irish by the government and other public bodies. Compliance with the Act is monitored by the An Coimisinéir Teanga (Irish Language Commissioner) which was established in 2004 and any complaints or concerns pertaining to the Act are brought to them. There are 35 sections included in
8930-693: Was spoken throughout Ireland, Isle of Man and parts of Scotland . It is the language of a large corpus of literature, including the Ulster Cycle . From the 12th century, Middle Irish began to evolve into modern Irish in Ireland, into Scottish Gaelic in Scotland, and into the Manx language in the Isle of Man . Early Modern Irish , dating from the 13th century, was the basis of the literary language of both Ireland and Gaelic-speaking Scotland. Modern Irish, sometimes called Late Modern Irish, as attested in
9025-442: Was unable to accomplish some everyday tasks, as portrayed in his documentary No Béarla . There is, however, a growing body of Irish speakers in urban areas, particularly in Dublin. Many have been educated in schools in which Irish is the language of instruction. Such schools are known as Gaelscoileanna at primary level. These Irish-medium schools report some better outcomes for students than English-medium schools. In 2009,
