Geology

The island is formed from a type of the Gneiss metamorphic rock known as Inishtrahull Gneiss, dated at 1700 million years old. Gneiss (ˈnaɪs is a common and widely distributed type of rock formed by high-grade regional metamorphic processes from preexisting formations that were originally Metamorphic rock is the result of the transformation of an existing rock type the protolith, in a process called Metamorphism, which means "change The gneiss is the oldest known rock on the Irish Islands, however studies have shown that the island was originally part of southern Greenland. Greenland (Kalaallit Nunaat meaning "Land of the Greenlanders" Grønland is a self-governing Danish Province located between the Roddy Muir, a Scottish Geologist, in the McCallion report, argued for geological links between Greenland, Colonsay, Islay and Inishtrahull. Colonsay ( Gaelic: Colbhasa is an Island in the Scottish Inner Hebrides, located north of Islay and south of Mull Islay (ˈaɪlə Ìle, ˈiːʎə a Scottish Island, known as "The Queen of the Hebrides" ( Banrìgh nan Eilean) is the southernmost

Muir visited this area and used Plate tectonics to conclude that Inishtrahull was part of the Southern tip of Greenland c. Plate tectonics (from Greek τέκτων tektōn "builder" or "mason" describes the large scale motions of Earth 's Lithosphere 1800 million years ago. He believes that Inishtrahull, Islay and Colonsay broke off the southern tip of Greenland, Islay and Colonsay moving to the western area of Scotland and Inishtrahull moving 1,300 km (800 mi) to the south east of Greenland off the Donegal Coast.

History

The name of the island is thought to refer to a bloody episode between some of the islanders and men of Islay (a near-by scottish island) where the men of Islay were tricked and slain while trying to rescue a woman. The island was inhabited until the 1920s and once a had a population of over 100 people. The 1920s is sometimes referred to as the " Jazz Age " or the " Roaring Twenties " when speaking about the United States and Canada It is over 0. 3 km² (80 acres) in size and crops of oats and potatoes were grown in the late 1800s. Fishing was a major part of the island's economy. Being the first and last point of landfall for cargo and passenger liners leaving from Scotland, Liverpool and Ireland's northerly ports the islanders offered fresh fish in exchange for whiskey and salt. Scotland ( Gaelic: Alba) is a Country in northwest Europethat occupies the northern third of the island of Great Britain. Liverpool ( is a City and Metropolitan borough of Merseyside, England along the eastern side of the Mersey Estuary Today there are a number of ruined houses and a ruined lighthouse on the Island as well as a new (1956) lighthouse.

The islands geographical location and lighthouse attract many unusual birds, as well as a population of Grey Seals. The island and its adjacent 90 metre depth tidal sound attract basking sharks and cetaceans in large numbers during the summer months. Many scuba-divers use the Islands Port Mór as a lunch spot while out surveying the hundreds of wrecks off its shores. Access to the island is limited by the dangerous tides and currents around Malin head and the island itself. There are landing restrictions enforced by the National Parks and Wildlife Service and the Commissioners of Irish Lights (present owners of the Island). The Commissioners of Irish Lights (CIL is the body that serves as the Lighthouse authority for all of the island of Ireland plus its adjacent seas and islands Particular care is requested by visitors during the breeding bird period of May - July.
