Geography (from Ancient Greek γεωγραφία geōgraphía; combining gê 'Earth' and gráphō 'write') is the study of the lands, features, inhabitants, and phenomena of Earth. Geography is an all-encompassing discipline that seeks an understanding of Earth and its human and natural complexities—not merely where objects are, but also how they have changed and come to be. While geography is specific to Earth, many concepts can be applied more broadly to other celestial bodies in the field of planetary science. Geography has been called "a bridge between natural science and social science disciplines."
Origins of many of the concepts in geography can be traced to Greek Eratosthenes of Cyrene, who may have coined the term "geographia" (c. 276 BC – c. 195/194 BC). The first recorded use of the word γεωγραφία was as the title of a book by Greek scholar Claudius Ptolemy (100 – 170 AD). This work created the so-called "Ptolemaic tradition" of geography, which included "Ptolemaic cartographic theory." However, the concepts of geography (such as cartography) date back to the earliest attempts to understand the world spatially, with the earliest example of an attempted world map dating to the 9th century BCE in ancient Babylon. The history of geography as a discipline spans cultures and millennia, being independently developed by multiple groups, and cross-pollinated by trade between these groups. The core concepts of geography consistent between all approaches are a focus on space, place, time, and scale.
Today, geography is an extremely broad discipline with multiple approaches and modalities. There have been multiple attempts to organize the discipline, including the four traditions of geography, and into branches. Techniques employed can generally be broken down into quantitative and qualitative approaches, with many studies taking mixed-methods approaches. Common techniques include cartography, remote sensing, interviews, and surveying. (Full article...)

Banff National Park is Canada's oldest national park, established in 1885 as Rocky Mountains Park. Located in Alberta's Rocky Mountains, 110–180 kilometres (68–112 mi) west of Calgary, Banff encompasses 6,641 square kilometres (2,564 sq mi) of mountainous terrain, with many glaciers and ice fields, dense coniferous forest, and alpine landscapes. Provincial forests and Yoho National Park are neighbours to the west, while Kootenay National Park is located to the south and Kananaskis Country to the southeast. The main commercial centre of the park is the town of Banff, in the Bow River valley.
The Canadian Pacific Railway was instrumental in Banff's early years, building the Banff Springs Hotel and Chateau Lake Louise, and attracting tourists through extensive advertising. In the early 20th century, roads were built in Banff, at times by war internees from World War I, and through Great Depression-era public works projects. The Icefields Parkway extends from Lake Louise, connecting to Jasper National Park in the north. (Full article...)
Mount Berlin is a glacier-covered volcano in Marie Byrd Land, Antarctica, 100 kilometres (62 mi) from the Amundsen Sea. It is a roughly 20-kilometre-wide (12 mi) mountain with parasitic vents that consists of two coalesced volcanoes: Berlin proper with the 2-kilometre-wide (1.2 mi) Berlin Crater and Merrem Peak with a 2.5-by-1-kilometre-wide (1.55 mi × 0.62 mi) crater, 3.5 kilometres (2.2 mi) away from Berlin. The summit of the volcano is 3,478 metres (11,411 ft) above sea level. It has a volume of 200 cubic kilometres (48 cu mi) and rises from the West Antarctic Ice Sheet. It is part of the Marie Byrd Land Volcanic Province. Trachyte is the dominant volcanic rock and occurs in the form of lava flows and pyroclastic rocks.
The volcano began erupting during the Pliocene and was active into the late Pleistocene and the Holocene. Several tephra layers encountered in ice cores all over Antarctica – but in particular at Mount Moulton – have been linked to Mount Berlin, which is the most important source of such tephras in the region. The tephra layers were formed by explosive eruptions that generated high eruption columns. Presently, fumarolic activity occurs at Mount Berlin and forms ice towers from freezing steam.

Suillus bovinus, also known as the Jersey cow mushroom or bovine bolete, is a pored mushroom of the genus Suillus in the family Suillaceae. A common fungus native to Europe and Asia, it has been introduced to North America and Australia. It was initially described as Boletus bovinus by Carl Linnaeus in 1753, and given its current binomial name by Henri François Anne de Roussel in 1806. It is an edible mushroom, though not highly regarded.
The fungus grows in coniferous forests in its native range, and pine plantations in countries where it has become naturalised. It forms symbiotic ectomycorrhizal associations with living trees by enveloping the tree's underground roots with sheaths of fungal tissue, and is sometimes parasitised by the related mushroom Gomphidius roseus. Suillus bovinus produces spore-bearing fruit bodies, often in large numbers, above ground. The mushroom has a convex grey-yellow or ochre cap reaching up to 10 cm (4 in) in diameter, which flattens with age. Like other boletes, it has tubes extending downward from the underside of the cap, rather than gills; spores escape at maturity through the tube openings, or pores. The pore surface is yellow. The stipe, more slender than those of other Suillus boletes, lacks a ring. (Full article...)
The High Middle Ages of Scotland encompass Scotland in the era between the death of Domnall II in 900 AD and the death of King Alexander III in 1286, which was an indirect cause of the Wars of Scottish Independence.
At the close of the ninth century, various competing kingdoms occupied the territory of modern Scotland. Scandinavian influence was dominant in the northern and western islands, Brythonic culture in the southwest, the Anglo-Saxon or English Kingdom of Northumbria in the southeast and the Pictish and Gaelic Kingdom of Alba in the east, north of the River Forth. By the tenth and eleventh centuries, northern Great Britain was increasingly dominated by Gaelic culture, and by the Gaelic regal lordship of Alba, known in Latin as either Albania or Scotia, and in English as "Scotland". From its base in the east, this kingdom acquired control of the lands lying to the south and ultimately the west and much of the north. It had a flourishing culture, comprising part of the larger Gaelic-speaking world and an economy dominated by agriculture and trade. (Full article...)
The Armenian genocide was the systematic destruction of the Armenian people and identity in the Ottoman Empire during World War I. Spearheaded by the ruling Committee of Union and Progress (CUP), it was implemented primarily through the mass murder of around one million Armenians during death marches to the Syrian Desert and the forced Islamization of others, primarily women and children.
Before World War I, Armenians occupied a somewhat protected, but subordinate, place in Ottoman society. Large-scale massacres of Armenians had occurred in the 1890s and 1909. The Ottoman Empire suffered a series of military defeats and territorial losses—especially during the 1912–1913 Balkan Wars—leading to fear among CUP leaders that the Armenians would seek independence. During their invasion of Russian and Persian territory in 1914, Ottoman paramilitaries massacred local Armenians. Ottoman leaders took isolated instances of Armenian resistance as evidence of a widespread rebellion, though no such rebellion existed. Mass deportation was intended to permanently forestall the possibility of Armenian autonomy or independence. (Full article...)
Holkham National Nature Reserve is England's largest national nature reserve (NNR). It is on the Norfolk coast between Burnham Overy Staithe and Blakeney, and is managed by Natural England with the cooperation of the Holkham Estate. Its 3,900 hectares (9,600 acres) comprise a wide range of habitats, including grazing marsh, woodland, salt marsh, sand dunes and foreshore. The reserve is part of the North Norfolk Coast Site of Special Scientific Interest, and the larger area is additionally protected through Natura 2000, Special Protection Area (SPA) and Ramsar listings, and is part of both an Area of Outstanding Natural Beauty (AONB) and a World Biosphere Reserve. Holkham NNR is important for its wintering wildfowl, especially pink-footed geese, Eurasian wigeon and brant geese, but it also has breeding waders, and attracts many migrating birds in autumn. Many scarce invertebrates and plants can be found in the dunes, and the reserve is one of the only two sites in the UK to have an antlion colony.
This stretch of coast originally consisted of salt marshes protected from the sea by ridges of shingle and sand, and Holkham's Iron Age fort stood at the end of a sandy spit surrounded by the tidal wetland. The Vikings navigated the creeks to establish Holkham village, but access to the former harbour was stopped by drainage and reclamation of the marshes between the coast and the shingle ridge which started in the 17th century, and was completed in 1859. The Holkham estate has been owned by the Coke family, later Earls of Leicester since 1609, and their seat at Holkham Hall is opposite the reserve's Lady Anne's Drive entrance. The 3rd Earl planted pines on the dunes to protect the pastures reclaimed by his predecessors from wind-blown sand. The national nature reserve was created in 1967 from 1,700 hectares (4,200 acres) of the Holkham Estate and 2,200 hectares (5,400 acres) of foreshore belonging to the Crown. (Full article...)
Fanno Creek is a 15-mile (24 km) tributary of the Tualatin River in the U.S. state of Oregon. Part of the drainage basin of the Columbia River, its watershed covers about 32 square miles (83 km) in Multnomah, Washington, and Clackamas counties, including about 7 square miles (18 km) within the Portland city limits.
From its headwaters in the Tualatin Mountains (West Hills) in southwest Portland, the creek flows generally west and south through the cities of Portland, Beaverton, Tigard and Durham, and unincorporated areas of Washington County. It enters the Tualatin River about 9 miles (14 km) above the Tualatin's confluence with the Willamette River at West Linn. (Full article...)
Lethbridge (/ˈlɛθbrɪdʒ/ LETH-brij) is a city in the province of Alberta, Canada. With a population of 106,550 in the 2023 municipal census. Lethbridge became the fourth Alberta city to surpass 100,000 people. The nearby Canadian Rocky Mountains contribute to the city's warm summers, mild winters, and windy climate. Lethbridge lies southeast of Calgary on the Oldman River.
Lethbridge is the commercial, financial, transportation and industrial centre of southern Alberta. The city's economy developed from drift mining for coal in the late 19th century and agriculture in the early 20th century. Half of the workforce is employed in the health, education, retail and hospitality sectors, and the top five employers are government-based. The only university in Alberta south of Calgary is in Lethbridge, and two of the three colleges in southern Alberta have campuses in the city. Cultural venues in the city include performing art theatres, museums and sports centres. (Full article...)
