A mountain is a large landform that stretches above the surrounding land in a limited area, usually in the form of a peak. A mountain is steeper than a hill. Mountains are formed through tectonic forces or volcanism and these forces can locally raise the surface of the earth. Mountains erode slowly through the action of rivers, weather conditions, a few mountains are isolated summits, but most occur in huge mountain ranges. High elevations on mountains produce colder climates than at sea level and these colder climates strongly affect the ecosystems of mountains, different elevations have different plants and animals. Because of the less hospitable terrain and climate, mountains tend to be used less for agriculture and more for resource extraction and recreation, the highest mountain on Earth is Mount Everest in the Himalayas of Asia, whose summit is 8,850 m above mean sea level. The highest known mountain on any planet in the Solar System is Olympus Mons on Mars at 21,171 m, there is no universally accepted definition of a mountain.
Elevation, relief, steepness and continuity have been used as criteria for defining a mountain, whether a landform is called a mountain may depend on local usage. The highest point in San Francisco, California, is called Mount Davidson, notwithstanding its height of 300 m, Mount Scott outside Lawton, Oklahoma is only 251 m from its base to its highest point. Whittows Dictionary of Physical Geography states Some authorities regard eminences above 600 metres as mountains, in addition, some definitions include a topographical prominence requirement, typically 100 or 500 feet. For a while, the US defined a mountain as being 1,000 feet or taller, any similar landform lower than this height was considered a hill. However, the United States Geological Survey concludes that these terms do not have technical definitions in the US, using these definitions, mountains cover 33% of Eurasia, 19% of South America, 24% of North America, and 14% of Africa. As a whole, 24% of the Earths land mass is mountainous, there are three main types of mountains, volcanic and block.
All three types are formed from plate tectonics, when portions of the Earths crust move, compressional forces, isostatic uplift and intrusion of igneous matter forces surface rock upward, creating a landform higher than the surrounding features. The height of the feature makes it either a hill or, if higher and steeper, major mountains tend to occur in long linear arcs, indicating tectonic plate boundaries and activity. Volcanoes are formed when a plate is pushed below another plate, at a depth of around 100 km, melting occurs in rock above the slab, and forms magma that reaches the surface. When the magma reaches the surface, it builds a volcanic mountain. Examples of volcanoes include Mount Fuji in Japan and Mount Pinatubo in the Philippines, the magma does not have to reach the surface in order to create a mountain, magma that solidifies below ground can still form dome mountains, such as Navajo Mountain in the US
Glacier National Park (U.S.)
Glacier National Park is a national park located in the U. S. state of Montana, on the Canada–United States border with the Canadian provinces of Alberta and British Columbia. The park encompasses over 1 million acres and includes parts of two ranges, over 130 named lakes, more than 1,000 different species of plants. This vast pristine ecosystem is the centerpiece of what has been referred to as the Crown of the Continent Ecosystem, the region that became Glacier National Park was first inhabited by Native Americans. Upon the arrival of European explorers, it was dominated by the Blackfeet in the east, under pressure the Blackfoot ceded the mountainous parts of their treaty lands in 1895 to the federal government, it became part of the park. Soon after the establishment of the park on May 11,1910 and these historic hotels and chalets are listed as National Historic Landmarks and a total of 350 locations are on the National Register of Historic Places. The mountains of Glacier National Park began forming 170 million years ago when ancient rocks were forced eastward up, known as the Lewis Overthrust, these sedimentary rocks are considered to have some of the finest fossilized examples of extremely early life found anywhere on Earth.
Of the estimated 150 glaciers which existed in the park in the mid-19th century, scientists studying the glaciers in the park have estimated that all the glaciers may disappear by 2030 if the current climate patterns persist. Glacier National Park has almost all its native plant and animal species. Large mammals such as Grizzly bears and mountain goats, as well as rare or endangered species like wolverines and Canadian lynxes, hundreds of species of birds, more than a dozen fish species, and a few reptile and amphibian species have been documented. The park has numerous ecosystems ranging from prairie to tundra, the easternmost forests of western redcedar and hemlock grow in the southwest portion of the park. Large forest fires are uncommon in the park, however, in 2003 over 13% of the park burned. Both parks were designated by the United Nations as Biosphere Reserves in 1976, according to archeological evidence, Native Americans first arrived in the Glacier area some 10,000 years ago. The earliest occupants with lineage to current tribes were the Flathead and Kootenai, the Blackfeet arrived around the beginning of the 18th century and soon dominated the eastern slopes of what became the park, as well as the Great Plains immediately to the east.
The park region provided the Blackfeet shelter from the winter winds of the plains. Today, the Blackfeet Indian Reservation borders the park in the east, while the Flathead Indian Reservation is located west, when the Blackfeet Reservation was first established in 1855 by the Lame Bull Treaty, it included the eastern area of the current park up to the Continental Divide. This established the current boundary between the park and the reservation, while exploring the Marias River in 1806, the Lewis and Clark Expedition came within 50 miles of the area that is now the park. A series of explorations after 1850 helped to shape the understanding of the area became the park. In 1885 George Bird Grinnell hired noted explorer James Willard Schultz to guide him on an expedition into what would become the park
A glacier is a persistent body of dense ice that is constantly moving under its own weight, it forms where the accumulation of snow exceeds its ablation over many years, often centuries. Glaciers slowly deform and flow due to stresses induced by their weight, creating crevasses and they abrade rock and debris from their substrate to create landforms such as cirques and moraines. Glaciers form only on land and are distinct from the much thinner sea ice, between 35°N and 35°S, glaciers occur only in the Himalayas, Rocky Mountains, a few high mountains in East Africa, New Guinea and on Zard Kuh in Iran. Glaciers cover about 10 percent of Earths land surface, continental glaciers cover nearly 13,000,000 km2 or about 98 percent of Antarcticas 13,200,000 km2, with an average thickness of 2,100 m. Greenland and Patagonia have huge expanses of continental glaciers, Glacial ice is the largest reservoir of fresh water on Earth. Within high altitude and Antarctic environments, the temperature difference is often not sufficient to release meltwater. A large piece of compressed ice, or a glacier, appears blue as large quantities of water appear blue and this is because water molecules absorb other colors more efficiently than blue.
The other reason for the color of glaciers is the lack of air bubbles. Air bubbles, which give a color to ice, are squeezed out by pressure increasing the density of the created ice. The word Glaceon is a loanword from French and goes back, via Franco-Provençal, to the Vulgar Latin glaciārium, derived from the Late Latin glacia, the processes and features caused by or related to glaciers are referred to as glacial. The process of establishment and flow is called glaciation. The corresponding area of study is called glaciology, Glaciers are important components of the global cryosphere. Glaciers are categorized by their morphology, thermal characteristics, and behavior, cirque glaciers form on the crests and slopes of mountains. A glacier that fills a valley is called a valley glacier, a large body of glacial ice astride a mountain, mountain range, or volcano is termed an ice cap or ice field. Ice caps have a less than 50,000 km2 by definition. Glacial bodies larger than 50,000 km2 are called ice sheets or continental glaciers, several kilometers deep, they obscure the underlying topography.
Only nunataks protrude from their surfaces, the only extant ice sheets are the two that cover most of Antarctica and Greenland. They contain vast quantities of water, enough that if both melted, global sea levels would rise by over 70 m
The Matterhorn is a mountain of the Alps, straddling the main watershed and border between Switzerland and Italy. It is a huge and near-symmetrical pyramidal peak in the extended Monte Rosa area of the Pennine Alps, whose summit is 4,478 metres high, making it one of the highest summits in the Alps and Europe. The four steep faces, rising above the glaciers, face the four compass points and are split by the Hörnli, Leone. The mountain overlooks the Swiss town of Zermatt in the canton of Valais to the north-east, just east of the Matterhorn is Theodul Pass, the main passage between the two valleys on its north and south sides and a trade route since the Roman Era. The Matterhorn was studied by Horace-Bénédict de Saussure in the eighteenth century. It remained unclimbed after most of the other great Alpine peaks had been attained, the first ascent of the Matterhorn was finally made in 1865 from Zermatt by a party led by Edward Whymper but ended disastrously when four of its members fell to their deaths on the descent.
That climb and disaster, portrayed in films, marked the end of the golden age of alpinism. The north face was not climbed until 1931, and is amongst the three biggest north faces of the Alps, known as the ‘The Trilogy’, the west face, which is the highest of the four, was completely climbed only in 1962. It is estimated that over 500 alpinists have died on the Matterhorn since the first climb in 1865, making it one of the deadliest peaks in the world. The current shape of the mountain is the result of erosion due to multiple glaciers diverging from the peak, such as the Matterhorn Glacier at the base of the north face. Sometimes referred to as the Mountain of Mountains, the Matterhorn has become an emblem of the Swiss Alps. Since the end of the 19th century, when railways were built in the area, each year a large number of mountaineers try to climb the Matterhorn from the Hörnli Hut via the northeast Hörnli ridge, the most popular route to the summit. Many trekkers undertake the 10-day-long circuit around the mountain, the Matterhorn is part of the Swiss Federal Inventory of Natural Monuments since 1983.
Decomposing Matterhorn yields Matter and Horn, here Matter is Matte in the case. Commonly, prepositions related to Zermatt are dropped as in Matterhorn, Mattertal, in Sebastian Münsters Cosmography, published in 1543, the name Matter is given to the Theodul Pass, which seems to be the origin of the present German name of the mountain. On Münsters topographical map this group is marked under the names of Augstalberg, the French name Cervin, from which the Italian term Cervino derives, stems from the Latin Mons Silvanus where silva, means forest which was corrupted to Selvin and Servin. The change of the first letter s to c is attributed to Horace Bénédict de Saussure, servius Galba, in order to carry out Caesars orders, came with his legions from Allobroges to Octodurum in the Valais, and pitched his camp there. It is unknown when the new name of Servin, or Cervin, replaced the old, the Matterhorn is named Gran Becca by the Valdôtains and Horu by the local Walliser German speaking people
The Weissmies 4,017 m is a mountain in the Pennine Alps in the canton of Valais in Switzerland near the village of Saas-Fee. It is the easternmost four-thousander of its range, the Weissmies is located on the main Alpine chain, on a massif separating the Saastal valley on the west and Simplon valley on the east. The massif consists of two main summits lying to the north at almost the same altitude, the Lagginhorn and Fletschhorn. The mountain lies between the Lagginjoch to the north and the Zwischbergen Pass to the south, the Weissmies is one of the 10 four-thousanders surrounding the Saastal, facing the Dom on the west, the third highest summit of the Alps. It was first climbed by Jakob Christian Häusser and Peter Josef Zurbriggen in 1855 via the Triftgrat, the east face was climbed first by J. A. Peebles, Mr E. P. Jackson and Margaret Jackson with guides P. Schlegel, U. Rubi and J. Martin on 17 October 1876, the more difficult south face was climbed in 1884 by C. H. Wilson, A. Burgener, J. Furrer.
Two weeks later, W. H. and E. Paine with T. Andenmatten, the approach to the Trift Glacier/south-west ridge route can now be made via lift to Hohsaas, which is located virtually at the edge of the glacier. The ascent from Hohsaas takes about 4 hours and involves slopes to 40 degrees and crevasses, another route starts from the Zwischbergen Pass at the foot of the southern ridge. The normal route to the summit of the Weissmies is, along with that of the Lagginghorn, one the easiest of the four-thousander mountains of the Alps to ascend
Forty-eight of the fifty states and the federal district are contiguous and located in North America between Canada and Mexico. The state of Alaska is in the northwest corner of North America, bordered by Canada to the east, the state of Hawaii is an archipelago in the mid-Pacific Ocean. The U. S. territories are scattered about the Pacific Ocean, the geography and wildlife of the country are extremely diverse. At 3.8 million square miles and with over 324 million people, the United States is the worlds third- or fourth-largest country by area, third-largest by land area. It is one of the worlds most ethnically diverse and multicultural nations, paleo-Indians migrated from Asia to the North American mainland at least 15,000 years ago. European colonization began in the 16th century, the United States emerged from 13 British colonies along the East Coast. Numerous disputes between Great Britain and the following the Seven Years War led to the American Revolution. On July 4,1776, during the course of the American Revolutionary War, the war ended in 1783 with recognition of the independence of the United States by Great Britain, representing the first successful war of independence against a European power.
The current constitution was adopted in 1788, after the Articles of Confederation, the first ten amendments, collectively named the Bill of Rights, were ratified in 1791 and designed to guarantee many fundamental civil liberties. During the second half of the 19th century, the American Civil War led to the end of slavery in the country. By the end of century, the United States extended into the Pacific Ocean. The Spanish–American War and World War I confirmed the status as a global military power. The end of the Cold War and the dissolution of the Soviet Union in 1991 left the United States as the sole superpower. The U. S. is a member of the United Nations, World Bank, International Monetary Fund, Organization of American States. The United States is a developed country, with the worlds largest economy by nominal GDP. It ranks highly in several measures of performance, including average wage, human development, per capita GDP. While the U. S. economy is considered post-industrial, characterized by the dominance of services and knowledge economy, the United States is a prominent political and cultural force internationally, and a leader in scientific research and technological innovations.
In 1507, the German cartographer Martin Waldseemüller produced a map on which he named the lands of the Western Hemisphere America after the Italian explorer and cartographer Amerigo Vespucci
Peru, officially the Republic of Peru, is a country in western South America. It is bordered in the north by Ecuador and Colombia, in the east by Brazil, in the southeast by Bolivia, in the south by Chile, and in the west by the Pacific Ocean. Peruvian territory was home to ancient cultures spanning from the Norte Chico civilization in Caral, one of the oldest in the world, to the Inca Empire, the largest state in Pre-Columbian America. The Spanish Empire conquered the region in the 16th century and established a Viceroyalty with its capital in Lima, ideas of political autonomy spread throughout Spanish America and Peru gained its independence, which was formally proclaimed in 1821. After the battle of Ayacucho, three years after proclamation, Peru ensured its independence, the country has undergone changes in government from oligarchic to democratic systems. Peru has gone through periods of political unrest and internal conflict as well as periods of stability, Peru is a representative democratic republic divided into 25 regions.
It is a country with a high Human Development Index score. Its main economic activities include mining, manufacturing and fishing, the Peruvian population, estimated at 31.2 million in 2015, is multiethnic, including Amerindians, Europeans and Asians. The main spoken language is Spanish, although a significant number of Peruvians speak Quechua or other native languages and this mixture of cultural traditions has resulted in a wide diversity of expressions in fields such as art, cuisine and music. The name of the country may be derived from Birú, the name of a ruler who lived near the Bay of San Miguel, Panama. When his possessions were visited by Spanish explorers in 1522, they were the southernmost part of the New World yet known to Europeans, when Francisco Pizarro explored the regions farther south, they came to be designated Birú or Perú. An alternative history is provided by the contemporary writer Inca Garcilasco de la Vega, son of an Inca princess, the Spanish Crown gave the name legal status with the 1529 Capitulación de Toledo, which designated the newly encountered Inca Empire as the province of Peru.
Under Spanish rule, the country adopted the denomination Viceroyalty of Peru, the earliest evidences of human presence in Peruvian territory have been dated to approximately 9,000 BC. Andean societies were based on agriculture, using such as irrigation and terracing, camelid husbandry. Organization relied on reciprocity and redistribution because these societies had no notion of market or money, the oldest known complex society in Peru, the Norte Chico civilization, flourished along the coast of the Pacific Ocean between 3,000 and 1,800 BC. These early developments were followed by archaeological cultures that developed mostly around the coastal, the Cupisnique culture which flourished from around 1000 to 200 BC along what is now Perus Pacific Coast was an example of early pre-Incan culture. The Chavín culture that developed from 1500 to 300 BC was probably more of a religious than a political phenomenon, on the coast, these included the civilizations of the Paracas, Nazca and the more outstanding Chimu and Mochica.
Their capital was at Chan Chan outside of modern-day Trujillo, in the 15th century, the Incas emerged as a powerful state which, in the span of a century, formed the largest empire in pre-Columbian America with their capital in Cusco
South America is a continent located in the western hemisphere, mostly in the southern hemisphere, with a relatively small portion in the northern hemisphere. It may be considered a subcontinent of the Americas, which is the used in nations that speak Romance languages. The reference to South America instead of other regions has increased in the last decades due to changing geopolitical dynamics. It is bordered on the west by the Pacific Ocean and on the north and east by the Atlantic Ocean, North America and it includes twelve sovereign states, a part of France, and a non-sovereign area. In addition to this, the ABC islands of the Kingdom of the Netherlands and Tobago, South America has an area of 17,840,000 square kilometers. Its population as of 2005 has been estimated at more than 371,090,000, South America ranks fourth in area and fifth in population. Brazil is by far the most populous South American country, with more than half of the population, followed by Colombia, Venezuela. In recent decades Brazil has concentrated half of the regions GDP and has become a first regional power, most of the population lives near the continents western or eastern coasts while the interior and the far south are sparsely populated.
Most of the continent lies in the tropics, the continents cultural and ethnic outlook has its origin with the interaction of indigenous peoples with European conquerors and immigrants and, more locally, with African slaves. Given a long history of colonialism, the majority of South Americans speak Portuguese or Spanish. South America occupies the portion of the Americas. The continent is delimited on the northwest by the Darién watershed along the Colombia–Panama border. Almost all of mainland South America sits on the South American Plate, South Americas major mineral resources are gold, copper, iron ore and petroleum. These resources found in South America have brought high income to its countries especially in times of war or of rapid growth by industrialized countries elsewhere. However, the concentration in producing one major export commodity often has hindered the development of diversified economies and this is leading to efforts to diversify production to drive away from staying as economies dedicated to one major export.
South America is one of the most biodiverse continents on earth, South America is home to many interesting and unique species of animals including the llama, piranha, vicuña, and tapir. The Amazon rainforests possess high biodiversity, containing a proportion of the Earths species. Brazil is the largest country in South America, encompassing around half of the land area
Pakistan, officially the Islamic Republic of Pakistan, is a federal parliamentary republic in South Asia on the crossroads of Central Asia and Western Asia. It is the sixth-most populous country with a population exceeding 200 million people, in terms of area, it is the 33rd-largest country in the world with an area covering 881,913 square kilometres. It is separated from Tajikistan by Afghanistans narrow Wakhan Corridor in the north, Pakistan is unique among Muslim countries in that it is the only country to have been created in the name of Islam. As a result of the Pakistan Movement led by Muhammad Ali Jinnah and it is an ethnically and linguistically diverse country, with a similarly diverse geography and wildlife. Initially a dominion, Pakistan adopted a constitution in 1956, becoming an Islamic republic, an ethnic civil war in 1971 resulted in the secession of East Pakistan as the new country of Bangladesh. The new constitution stipulated that all laws were to conform to the injunctions of Islam as laid down in the Quran.
Pakistan has an economy with a well-integrated agriculture sector. The Pakistani economy is the 24th-largest in the world in terms of purchasing power and it is ranked among the emerging and growth-leading economies of the world, and is backed by one of the worlds largest and fastest-growing middle classes. The post-independence history of Pakistan has been characterised by periods of military rule, the country continues to face challenging problems such as illiteracy and corruption, but has substantially reduced poverty and terrorism and expanded per capita income. It is a member of CERN. Pakistan is a signatory to the Kyoto Protocol, the Paris Agreement, the name Pakistan literally means land of the pure in Urdu and Persian. It is a play on the word pāk meaning pure in Persian and Pashto, the letter i was incorporated to ease pronunciation and form the linguistically correct and meaningful name. Some of the earliest ancient human civilisations in South Asia originated from areas encompassing present-day Pakistan, the earliest known inhabitants in the region were Soanian during the Lower Paleolithic, of whom stone tools have been found in the Soan Valley of Punjab.
The Vedic Civilization, characterised by Indo-Aryan culture, laid the foundations of Hinduism, Multan was an important Hindu pilgrimage centre. The Vedic civilisation flourished in the ancient Gandhāran city of Takṣaśilā, the Indo-Greek Kingdom founded by Demetrius of Bactria included Gandhara and Punjab and reached its greatest extent under Menander, prospering the Greco-Buddhist culture in the region. Taxila had one of the earliest universities and centres of education in the world. At its zenith, the Rai Dynasty of Sindh ruled this region, the Pala Dynasty was the last Buddhist empire, under Dharampala and Devapala, stretched across South Asia from what is now Bangladesh through Northern India to Pakistan. The Arab conqueror Muhammad bin Qasim conquered the Indus valley from Sindh to Multan in southern Punjab in 711 AD, the Pakistan governments official chronology identifies this as the time when the foundation of Pakistan was laid
Montana /mɒnˈtænə/ is a state in the Western region of the United States. The states name is derived from the Spanish word montaña, Montana has several nicknames, although none official, including Big Sky Country and The Treasure State, and slogans that include Land of the Shining Mountains and more recently The Last Best Place. Montana has a 545-mile border with three Canadian provinces, British Columbia and Saskatchewan, the state to do so. It borders North Dakota and South Dakota to the east, Wyoming to the south, Montana is ranked 4th in size, but 44th in population and 48th in population density of the 50 United States. The western third of Montana contains numerous mountain ranges, smaller island ranges are found throughout the state. In total,77 named ranges are part of the Rocky Mountains, the eastern half of Montana is characterized by western prairie terrain and badlands. The economy is based on agriculture, including ranching and cereal grain farming. Other significant economic activities include oil, gas and hard rock mining, the health care and government sectors are significant to the states economy.
Millions of tourists annually visit Glacier National Park, the Little Bighorn Battlefield National Monument, the name Montana comes from the Spanish word Montaña and the Latin word Montana, meaning mountain, or more broadly, mountainous country. Montaña del Norte was the name given by early Spanish explorers to the mountainous region of the west. The name was changed by Representatives Henry Wilson and Benjamin F. Harding, when Ashley presented a bill to establish a temporary government in 1864 for a new territory to be carved out of Idaho, he again chose Montana Territory. This time Rep. Samuel Cox, of Ohio, objected to the name, Cox complained that the name was a misnomer given most of the territory was not mountainous and that a Native American name would be more appropriate than a Spanish one. Other names such as Shoshone were suggested, but it was decided that the Committee on Territories could name it whatever they wanted, with an area of 147,040 square miles, Montana is slightly larger than Japan.
It is the fourth largest state in the United States after Alaska and California, the largest landlocked U. S. state, and the worlds 56th largest national state/province subdivision. To the north, Montana shares a 545-mile border with three Canadian provinces, British Columbia and Saskatchewan, the state to do so. It borders North Dakota and South Dakota to the east, Wyoming to the south, the states topography is roughly defined by the Continental Divide, which splits much of the state into distinct eastern and western regions. Most of Montanas 100 or more named mountain ranges are in the western half. The Absaroka and Beartooth ranges in the states south-central part are part of the Central Rocky Mountains
Scottish Gaelic or Scots Gaelic, sometimes referred to as Gaelic, is a Celtic language native to Scotland. A member of the Goidelic branch of the Celtic languages, Scottish Gaelic, like Modern Irish and Manx, developed out of Middle Irish. The 2011 census of Scotland showed that a total of 57,375 people in Scotland could speak Gaelic at that time, the census results indicate a decline of 1,275 Gaelic speakers from 2001. A total of 87,056 people in 2011 reported having some facility with Gaelic compared to 93,282 people in 2001, only about half of speakers were fully literate in the language. Nevertheless, revival efforts exist and the number of speakers of the language under age 20 has increased, Scottish Gaelic is neither an official language of the European Union nor the United Kingdom. Outside Scotland, a group of dialects collectively known as Canadian Gaelic are spoken in parts of Atlantic Canada, mainly Nova Scotia and Prince Edward Island. In the 2011 census, there were 7,195 total speakers of Gaelic languages in Canada, with 1,365 in Nova Scotia and Prince Edward Island where the responses mainly refer to Scottish Gaelic.
About 2,320 Canadians in 2011 claimed Gaelic languages as their mother tongue, with over 300 in Nova Scotia, aside from Scottish Gaelic, the language may be referred to simply as Gaelic. In Scotland, the word Gaelic in reference to Scottish Gaelic specifically is pronounced, outside Ireland and Great Britain, Gaelic may refer to the Irish language. Scottish Gaelic should not be confused with Scots, the Middle English-derived language varieties which had come to be spoken in most of the Lowlands of Scotland by the modern era. Prior to the 15th century, these dialects were known as Inglis by its own speakers, from the late 15th century, however, it became increasingly common for such speakers to refer to Scottish Gaelic as Erse and the Lowland vernacular as Scottis. Today, Scottish Gaelic is recognised as a language from Irish. Gaelic in Scotland was mostly confined to Dál Riata until the 8th century, when it began expanding into Pictish areas north of the Firth of Forth, by 900, Pictish appears to have become extinct, completely replaced by Gaelic.
An exception might be made for the Northern Isles, however, though the Pictish language did not disappear suddenly, a process of Gaelicisation was clearly underway during the reigns of Caustantín and his successors. By a certain point, probably during the 11th century, all the inhabitants of Alba had become fully Gaelicised Scots, by the 10th century, Gaelic had become the dominant language throughout northern and western Scotland, the Gaelo-Pictic Kingdom of Alba. Its spread to southern Scotland, was even and totalizing. Place name analysis suggests dense usage of Gaelic in Galloway and adjoining areas to the north and west as well as in West Lothian, less dense usage is suggested for north Ayrshire, the Clyde Valley and eastern Dumfriesshire. In south-eastern Scotland, there is no evidence that Gaelic was ever widely spoken, the area shifted from Cumbric to Old English during its long incorporation into the Anglo-Saxon Kingdom of Northumbria
