Geography (from Ancient Greekγεωγραφίαgeōgraphía; 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...)

A hot windstorm brings dust from the surrounding desert, July 3, 1942
Manzanar is the site of one of ten American concentration camps, where more than 120,000 Japanese Americans were incarcerated during World War II from March 1942 to November 1945. Although it had over 10,000 inmates at its peak, it was one of the smaller internment camps. It is located at the foot of the Sierra Nevada mountains in California's Owens Valley, between the towns of Lone Pine to the south and Independence to the north, approximately 230 miles (370 km) north of Los Angeles. Manzanar means "apple orchard" in Spanish. The Manzanar National Historic Site, which preserves and interprets the legacy of Japanese American incarceration in the United States, was identified by the United States National Park Service as the best-preserved of the ten former camp sites.
The first Japanese Americans arrived at Manzanar in March 1942, just one month after President Franklin D. Roosevelt signed Executive Order 9066, to build the camp their families would be staying in. Manzanar was in operation as an internment camp from 1942 until 1945. Since the last of those incarcerated left in 1945, former detainees and others have worked to protect Manzanar and to establish it as a National Historic Site to ensure that the history of the site, along with the stories of those who were incarcerated there, is recorded for current and future generations. The primary focus is the Japanese American incarceration era, as specified in the legislation that created the Manzanar National Historic Site. The site also interprets the former town of Manzanar, the ranch days, the settlement by the Owens Valley Paiute, and the role that water played in shaping the history of the Owens Valley.

17th- or 18th-century Hajj certificate showing the Kaaba within the Masjid al-Haram
Hajj: Journey to the Heart of Islam was an exhibition held at the British Museum in London from 26 January to 15 April 2012. It was the world's first major exhibition telling the story, visually and textually, of the hajj – the pilgrimage to Mecca which is one of the five pillars of Islam. Textiles, manuscripts, historical documents, photographs, and art works from many different countries and eras were displayed to illustrate the themes of travel to Mecca, hajj rituals, and the Kaaba. More than two hundred objects were included, drawn from forty public and private collections in a total of fourteen countries. The largest contributor was David Khalili's family trust, which lent many objects that would later be part of the Khalili Collection of Hajj and the Arts of Pilgrimage.
The nature reserve is managed primarily for bird conservation, particularly through control and improvement of wetland, heath and grassland habitats, with particular emphasis on encouraging nationally uncommon breeding species such as the bittern, stone-curlew, marsh harrier, nightjar and nightingale. The diversity of habitats has also led to a wide variety of other animals and plants being recorded on the site. (Full article...)

Shoshone National Forest (/ʃoʊˈʃoʊni/shoh-SHOH-nee) is the first federally protected National Forest in the United States and covers nearly 2,500,000 acres (1,000,000 ha) in the state of Wyoming. Originally a part of the Yellowstone Timberland Reserve, the forest is managed by the United States Forest Service and was created by an act of Congress and signed into law by U.S. PresidentBenjamin Harrison in 1891. Shoshone National Forest is one of the first nationally protected land areas anywhere. Native Americans have lived in the region for at least 10,000 years, and when the region was first explored by European adventurers, forestlands were occupied by several different tribes. Never heavily settled or exploited, the forest has retained most of its wildness. Shoshone National Forest is a part of the Greater Yellowstone Ecosystem, a nearly unbroken expanse of federally protected lands encompassing an estimated 20,000,000 acres (8,100,000 ha).
Henry McNish (11 September 1874 – 24 September 1930), often referred to as Harry McNish or by the nickname Chippy, was the carpenter on Sir Ernest Shackleton's Imperial Trans-Antarctic Expedition of 1914–1917. He was responsible for much of the work that ensured the crew's survival after their ship, the Endurance, was destroyed when it became trapped in pack ice in the Weddell Sea. He modified the small boat, James Caird, that allowed Shackleton and five men (including McNish) to make a voyage of hundreds of miles to fetch help for the rest of the crew.
After the expedition he returned to work in the Merchant Navy and eventually emigrated to New Zealand, where he worked on the docks in Wellington until poor health forced his retirement. He died destitute in the Ohiro Benevolent Home in Wellington. (Full article...)

The empire in 661, when it reached its greatest extent
The Li family founded the dynasty after taking advantage of a period of Sui decline and precipitating their final collapse, in turn inaugurating a period of progress and stability in the first half of the dynasty's rule. The dynasty was formally interrupted during 690–705 when Empress Wu Zetian seized the throne, proclaiming the Wu Zhou dynasty and becoming the only legitimate Chinese empress regnant. The An Lushan rebellion (755–763) led to devastation and the decline of central authority during the latter half of the dynasty. Like the previous Sui dynasty, the Tang maintained a civil-service system by recruiting scholar-officials through standardised examinations and recommendations to office. The rise of regional military governors known as jiedushi during the 9th century undermined this civil order. The dynasty and central government went into decline by the latter half of the 9th century; agrarian rebellions resulted in mass population loss and displacement, widespread poverty, and further government dysfunction that ultimately ended the dynasty in 907.

The city is named after the nearby Lake Winnipeg; the name comes from the Western Cree words for "muddy water" – winipīhk. The region was a trading centre for Indigenous peoples long before the arrival of Europeans; it is the traditional territory of the Anishinabe (Ojibway), Ininew (Cree), Oji-Cree, Dene, and Dakota, and is the birthplace of the Métis Nation. French traders built the first fort, Fort Rouge, on the site in 1738. A settlement was later founded by the Selkirk settlers of the Red River Colony in 1812, the nucleus of which was incorporated as the City of Winnipeg in 1873. Being far inland, the city's climate is extremely seasonal (continental) even by Canadian standards, with average January highs of around −11 °C (12 °F) and average July highs of 26 °C (79 °F).

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...)

Surtsey, sixteen days after the onset of the eruption
Surtsey ("Surtr's island" in Icelandic, Icelandic pronunciation:[ˈsʏr̥(t)sˌeiː]ⓘ) is an uninhabited volcanic island located in the Vestmannaeyjararchipelago off the southern coast of Iceland. At Surtsey is the southernmost point of Iceland. It was formed in a volcanic eruption which began 130 metres (430 feet) below sea level, and reached the surface on 14 November 1963. The eruption lasted until 5 June 1967, when the island reached its maximum size of 2.7 km2 (1.0 sq mi). Since then, wave erosion has caused the island to steadily diminish in size: as of 2012[update], its surface area was 1.3 km2 (0.50 sq mi). The most recent survey (2007) shows the island's maximum elevation at 155 m (509 ft) above sea level.
The new island was named after Surtr, a fire jötunn or giant from Norse mythology. It was intensively studied by volcanologists during its eruption, and afterwards by botanists and other biologists as life forms gradually colonised the originally barren island. The undersea vents that produced Surtsey are part of the Vestmannaeyjar submarine volcanic system, part of the fissure of the sea floor called the Mid-Atlantic Ridge. Vestmannaeyjar also produced the famous eruption of Eldfell on the island of Heimaey in 1973. The eruption that created Surtsey also created a few other small islands along this volcanic chain, such as Jólnir and other, unnamed peaks. Most of these eroded away fairly quickly. It is estimated that Surtsey will remain above sea level until at least the year 2100. (Full article...)
The first volcanic activity at Tuzgle occurred 650,000 years ago and formed the Tuzgle Ignimbrite. Subsequently, lava domes and several lava flows were erupted; scientists have proposed two different schemes of naming the units. The most recent lava flows are dated at 300,000 years ago and volcanic activity may have continued into the Holocene. Several thermal springs are associated with the volcano, and some have been investigated for possible geothermal energy production. Sulfur was formerly mined on the mountain. (Full article...)
The region was first settled by Paleo-IndianNative Americans; by the time European American explorers arrived, it was inhabited by Skagit tribes. By the early 19th century, the region was visited by fur trappers and several British and American companies vied for control over the fur trade. After the Canada–United States border was set at the 49th parallel in 1846, explorers came to chart potential routes through the mountains for roads and railroads. Limited mining and logging occurred from the late 19th century to the early 20th century. The first significant human impact in the region occurred in the 1920s when several dams were built in the Skagit River valley to generate hydroelectric power. Environmentalists then campaigned to preserve the remaining wilderness, culminating on October 2, 1968, with the designation of North Cascades National Park. (Full article...)
The sinusoidal projection is a pseudocylindrical equal-areamap projection. Used as early as the 16th century, this projection shows distances accurately along the central meridian and the equator; areas furthest from these lines are the most distorted.
The Robinson projection is a map projection of a world map which shows the entire world at once. It was devised by Arthur H. Robinson in 1963 in response to an appeal from the Rand McNally company for a good compromise to the problem of readily showing the whole globe as a flat image. The company has used the projection since that time, and the National Geographic Society used the Robinson from 1988 to 1998.

A satellite photo of Great Britain and part of Ireland showing the extent of snow cover during the winter of 2009–2010, the coldest in Europe since 1981–82. Starting on 16 December 2009 a persistent weather pattern brought cold moist air from the north with systems undergoing cyclogenesis from North American storms moving across the Atlantic Ocean to the west, and saw many parts of Europe experiencing heavy snowfall and record low temperatures.
This picture is a panoramic map of North Cascades National Park, as viewed from the east, created in 1987 by Austrian painter and cartographer Heinrich C. Berann for the National Park Service.
The van der Grinten projection is a compromise map projection that is neither equal-area nor conformal. It projects the entire Earth into a circle, though the polar regions are subject to extreme distortion. The projection was the first of four proposed by Alphons J. van der Grinten in 1904, and, unlike perspective projections, is an arbitrary geometric construction on the plane. It was adopted as the National Geographic Society's reference map of the world from 1922 until 1988.

A detailed eighteenth-century map of Scandinavia by J. B. Homann, depicting Denmark, Norway, Sweden, Finland and the Baltic states of Livonia, Latvia and Curlandia. The map notes fortified cities, villages, roads, bridges, forests, castles and topography. The elaborate title cartouche in the upper left quadrant features angels supporting a title curtain and a medallion supporting an alternative title in French, "Les Trois Covronnes du Nord".
Born in 1664, Homann became an engraver and cartographer in the late 17th century, and opened his own publishing house in 1702. In 1715 Emperor Charles VI appointed him Imperial Geographer of the Holy Roman Empire. Homann held the position until his death in 1724.
The frontispiece of the 1920 edition of Tod's Annals and Antiquities of Rajast'han
Lieutenant-Colonel James Tod (20 March 1782 – 18 November 1835) was an officer of the British East India Company and an Oriental scholar. He combined his official role and his amateur interests to create a series of works about the history and geography of India, and in particular the area then known as Rajputana that corresponds to the present day state of Rajasthan, and which Tod referred to as Rajast'han.
Tod was born in London and educated in Scotland. He joined the East India Company as a military officer and travelled to India in 1799 as a cadet in the Bengal Army. He rose quickly in rank, eventually becoming captain of an escort for an envoy in a Sindian royal court. After the Third Anglo-Maratha War, during which Tod was involved in the intelligence department, he was appointed Political Agent for some areas of Rajputana. His task was to help unify the region under the control of the East India Company. During this period Tod conducted most of the research that he would later publish. Tod was initially successful in his official role, but his methods were questioned by other members of the East India Company. Over time, his work was restricted and his areas of oversight were significantly curtailed. In 1823, owing to declining health and reputation, Tod resigned his post as Political Agent and returned to England. (Full article...)
A map of the United States showing its 50 states, federal district and five inhabited territories. Alaska, Hawaii, and the territories are shown at different scales, and the Aleutian Islands and the uninhabited northwestern Hawaiian Islands are omitted from the map. The United States of America is a federal republic consisting of 50 states, a federal district (Washington, D.C., the capital city of the United States), five major territories, and various minor islands. Both the states and the United States as a whole are each sovereign jurisdictions. The Tenth Amendment to the United States Constitution allows states to exercise all powers of government not delegated to the federal government. Each state has its own constitution and government, and all states and their residents are represented in the federal Congress, a bicameral legislature consisting of the Senate and the House of Representatives. Each state elects two senators, while representatives are distributed among the states in proportion to the most recent constitutionally mandated decennial census. Additionally, each state is entitled to select a number of electors to vote in the Electoral College, the body that elects the president of the United States, equal to the total of representatives and senators in Congress from that state. The federal district does not have representatives in the Senate, but has a non-voting delegate in the House, and it is also entitled to electors in the Electoral College. Congress can admit more states, but it cannot create a new state from territory of an existing state or merge two or more states into one without the consent of all states involved, and each new state is admitted on an equal footing with the existing states.

Generation Z (often shortened to Gen Z), also known as Zoomers, is the demographiccohort succeeding Millennials and preceding Generation Alpha. Researchers and popular media use the mid-to-late 1990s as starting birth years and the early 2010s as ending birth years, with the generation most frequently being defined as people born from 1997 to 2012. Most members of Generation Z are the children of younger baby boomers or Generation X. (Full article...)

At more than 500,000 acres (200,000 ha), North Cascades National Park is the largest of the three National Park Service units that comprise the North Cascades National Park Complex. North Cascades National Park consists of a northern and southern section, bisected by the Skagit River that flows through Ross Lake National Recreation Area. Lake Chelan National Recreation Area lies on the southern border of the south unit of the park. In addition to the two national recreation areas, other protected lands including several national forests and wilderness areas, as well as Canadian provincial parks in British Columbia, nearly surround the park. North Cascades National Park features the rugged mountain peaks of the North Cascades Range, the most expansive glacial system in the contiguous United States, the headwaters of numerous waterways, and vast forests with the highest degree of flora biodiversity of any American national park.

Map: Strebe, using GeocartThe Hammer retroazimuthal projection is a modified azimuthal proposed by Ernst Hermann Heinrich Hammer in 1910. As a retroazimuthal projection, azimuths (directions) are correct from any point to the designated center point. In whole-world presentation, the back and front hemispheres overlap, making the projection a surjective function. Here, the frontside and backside hemispheres, both with a 15° graticule and center point of 45°N, 90°W, are presented side-by-side.
Map credit: Heinrich C. BerannYellowstone National Park is an American national park located mostly in Wyoming and extending into Montana and Idaho. It was established by the U.S. Congress and signed into law by President Ulysses S. Grant on March 1, 1872. Yellowstone was the first national park in the U.S. and is also widely held to be the first national park in the world. The park is known for its wildlife and its many geothermal features, especially the Old Faithful geyser, one of its most popular landmarks. It has many types of ecosystems, but the subalpine forest is the most abundant. The park is part of the South Central Rockies forests ecoregion. In 1978, Yellowstone was named a World Heritage Site by UNESCO.
