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...)

William Speirs Bruce FRSE (1 August 1867 – 28 October 1921) was a British naturalist, polar scientist and oceanographer who organised and led the Scottish National Antarctic Expedition (SNAE, 1902–04) to the South Orkney Islands and the Weddell Sea. Among other achievements, the expedition established the first permanent weather station in Antarctica. Bruce later founded the Scottish Oceanographical Laboratory in Edinburgh, but his plans for a transcontinental Antarctic march via the South Pole were abandoned because of lack of public and financial support.
In 1892 Bruce gave up his medical studies at the University of Edinburgh and joined the Dundee Whaling Expedition to Antarctica as a scientific assistant. This was followed by Arctic voyages to Novaya Zemlya, Spitsbergen and Franz Josef Land. In 1899 Bruce, by then Britain's most experienced polar scientist, applied for a post on Robert Falcon Scott's Discovery Expedition, but delays over this appointment and clashes with Royal Geographical Society (RGS) president Sir Clements Markham led him instead to organise his own expedition, and earned him the permanent enmity of the geographical establishment in London. Although Bruce received various awards for his polar work, including an honorary doctorate from the University of Aberdeen, neither he nor any of his SNAE colleagues were recommended by the RGS for the prestigious Polar Medal.

The peregrine falcon (Falco peregrinus), also known simply as the peregrine, and historically as the duck hawk in North America, is a cosmopolitan bird of prey (raptor) in the family Falconidae. A large, crow-sized falcon, it has a blue-grey back, barred white underparts, and a black head. The peregrine is renowned for its speed. It can reach over 320 km/h (200 mph) during its characteristic hunting stoop (high-speed dive), making it the fastest animal on the planet. According to a National Geographic TV program, the highest measured speed of a peregrine falcon is 389 km/h (242 mph). As is typical for bird-eating (avivore) raptors, peregrine falcons are sexually dimorphic, with females being considerably larger than males.
The peregrine's breeding range includes land regions from the Arctic tundra to the tropics. It can be found nearly everywhere on Earth, except extreme polar regions, very high mountains, and most tropical rainforests; the only major ice-free landmass from which it is entirely absent is New Zealand. This makes it the world's most widespread raptor and one of the most widely found wild bird species. In fact, the only land-based bird species found over a larger geographic area owes its success to human-led introduction; the domestic and feral pigeons are both domesticate forms of the rock dove, which are a major prey species for Eurasian Peregrine populations. Due to their prevalence over most other bird species in cities, feral pigeons support many peregrine populations as a staple food source, especially in urban settings. (Full article...) -
Northern England, or the North of England, is a region that forms the northern part of England and mainly corresponds to the historic counties of Cheshire, Cumberland, Durham, Lancashire, Northumberland, Westmorland and Yorkshire. The region also coincides with the medieval era borders of Anglian Northumbria, the Anglo-Scandinavian Kingdom of Jorvik, and the Brythonic Celtic Hen Ogledd kingdoms.
The North is a grouping of three statistical regions: the North East, the North West, and Yorkshire and the Humber. These had a combined population of 15.5 million at the 2021 census, an area of 37,331 km2 (14,414 square miles) and 17 cities. (Full article...) -
Launching the James Caird from the shore of Elephant Island, 24 April 1916
The voyage of the James Caird was a journey of 1,300 kilometres (800 mi) from Elephant Island in the South Shetland Islands through the Southern Ocean to South Georgia, undertaken by Sir Ernest Shackleton and five companions to obtain rescue for the main body of the stranded Imperial Trans-Antarctic Expedition of 1914–1917. Many historians[who?] regard the voyage of the crew in a 22.5-foot (6.9 m) ship's boat through the "Furious Fifties" as the greatest small-boat journey ever completed.
In October 1915, pack ice in the Weddell Sea had sunk the main expedition ship Endurance, leaving Shackleton and his 27 companions adrift on a floe. They drifted northward until April 1916, when the floe on which they were camped broke up; they made their way in the ship's boats to Elephant Island. Shackleton decided to sail one of the boats with a small crew to South Georgia to seek help. It was not the closest human settlement but the only one that did not require them to sail into the prevailing westerlies. (Full article...) -
Right whales are three species of large baleen whales of the genus Eubalaena: the North Atlantic right whale (E. glacialis), the North Pacific right whale (E. japonica) and the Southern right whale (E. australis). They are classified in the family Balaenidae with the bowhead whale. Right whales have rotund bodies with arching rostrums, V-shaped blowholes and dark gray or black skin. The most distinguishing feature of a right whale is the rough patches of skin on its head, which appear white due to parasitism by whale lice. Right whales are typically 13–17 m (43–56 ft) long and weigh up to 100 short tons (91 t; 89 long tons) or more.
All three species are migratory, moving seasonally to feed or give birth. The warm equatorial waters form a barrier that isolates the northern and southern species from one another although the southern species, at least, has been known to cross the equator. In the Northern Hemisphere, right whales tend to avoid open waters and stay close to peninsulas and bays and on continental shelves, as these areas offer greater shelter and an abundance of their preferred foods. In the Southern Hemisphere, right whales feed far offshore in summer, but a large portion of the population occur in near-shore waters in winter. Right whales feed mainly on copepods but also consume krill and pteropods. They may forage the surface, underwater or even the ocean bottom. During courtship, males gather into large groups to compete for a single female, suggesting that sperm competition is an important factor in mating behavior. Gestation tends to last a year, and calves are weaned at eight months old. (Full article...) -
Upper Table Rock and Lower Table Rock are two prominent volcanic plateaus located just north of the Rogue River in Jackson County, Oregon, U.S. Created by an andesitic lava flow approximately seven million years ago and shaped by erosion, they now stand about 800 feet (240 m) above the surrounding Rogue Valley. The Table Rocks are jointly owned; The Nature Conservancy is responsible for 3,591 acres (1,453 ha), while the Bureau of Land Management is responsible for 1,280 acres (520 ha).
Native Americans have inhabited the Table Rocks area for at least 15,000 years before European-American settlement. Starting in the mid-19th century during a gold rush, the settlers forced the Takelma tribe away from the Table Rocks and into reservations. The surrounding area was quickly developed. The Table Rock post office was established in 1872, an airstrip was built atop Lower Table Rock in 1948, and a very high frequency omni-directional range (VOR) aviation tower was constructed on Upper Table Rock in the 1960s. The Table Rocks were not protected until the 1970s. (Full article...) -
Forest Park is a public municipal park in the Tualatin Mountains west of downtown Portland, Oregon, United States. Stretching for more than 8 miles (13 km) on hillsides overlooking the Willamette River, it is one of the country's largest urban forest reserves. The park, a major component of a regional system of parks and trails, covers more than 5,100 acres (2,064 ha) of mostly second-growth forest with a few patches of old growth. More than 80 miles (130 km) of recreational trails, including the Wildwood Trail segment of the city's 40-Mile Loop system, crisscross the park.
As early as the 1860s, civic leaders sought to create a natural preserve in the woods near Portland. Their efforts led to the creation of a municipal park commission that in 1903 hired the Olmsted Brothers landscape architectural firm to develop a plan for Portland's parks. Acquiring land through donations, transfers from Multnomah County, and delinquent tax foreclosures, the city eventually acted on a proposal by the City Club of Portland and combined parcels totaling about 4,000 acres (1,600 ha) to create the reserve. Formally dedicated in 1948, it ranks 19th in size among parks within U.S. cities, according to the Trust for Public Land. (Full article...) -
Elcor is a ghost town, or more properly, an extinct town, in the U.S. state of Minnesota that was inhabited between 1897 and 1956. It was built on the Mesabi Iron Range near the city of Gilbert in St. Louis County. Elcor was its own unincorporated community before it was abandoned and was never a neighborhood proper of the city of Gilbert. Not rating a figure in the national census, the people of Elcor were only generally considered to be citizens of Gilbert. The area where Elcor was located was annexed by Gilbert when its existing city boundaries were expanded after 1969.
In November 1890, the seven Merritt brothers discovered ore near Mountain Iron, triggering an unparalleled iron rush to the Mesabi Range. The Elba mine was opened in 1897, and the town was platted under the direction of Don H. Bacon, president of the Minnesota Iron Company. A second nearby mine, the Corsica, was opened in 1901. The community was first called "Elba" after the name of the first underground mine (the name "Elcor" was formed later by combining the first syllables of each mine's name). The Elba and Corsica mines were both leased by Pickands Mather and Company after the formation of the United States Steel Corporation. An influx of people of many ethnicities and many nations followed, and Elcor became a microcosm of U.S. immigration, mirroring the cultural assimilation of the time. At its peak around 1920, Elcor had two churches, a post office, a general store, a primary school, a railroad station, and its own law enforcement, and housed a population of nearly 1,000.

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.

The Romney Literary Society (also known as the Literary Society of Romney) existed from January 30, 1819, to February 15, 1886, in Romney, West Virginia. Established as the Polemic Society of Romney, it became the first organization of its kind in the present-day state of West Virginia, and one of the first in the United States. The society was founded by nine prominent men of Romney with the objectives of advancing literature and science, purchasing and maintaining a library, and improving educational opportunities.
The society debated an extensive range of scientific and social topics, often violating its own rules which banned religious and political subjects. Even though its membership was relatively small, its debates and activities were frequently discussed throughout the Potomac Highlands region, and the organization greatly influenced trends of thought in the Romney community and surrounding areas.

Valley View is a mid-19th-century Greek Revival residence and farm overlooking the South Branch Potomac River northwest of Romney, West Virginia. The house is atop a promontory where Depot Valley joins the South Branch Potomac River valley.
The Valley View property was part of the South Branch Survey of the Northern Neck Proprietary, a large tract that was inherited by Thomas Fairfax, 6th Lord Fairfax of Cameron, in 1719. It was settled by John Collins and his family in 1749, and acquired by the Parsons family before 1772. The Valley View house was built by James Parsons Jr. in 1855. After the Civil War, Parsons' widow sold the farm to Charles Harmison. His wife, Elizabeth Harmison, inspired by her childhood Virginia home, Western View, and the scenic South Branch Potomac River views, named the farm Valley View. The most recent of a series of owners, the Mayhew family, bought the property in 1979. Valley View's current proprietors, Robert and Kim Mayhew, have restored the historic residence and grounds.

The Song dynasty (/sʊŋ/) was an imperial dynasty of China that ruled from 960 to 1279. The dynasty was founded by Emperor Taizu of Song, who usurped the throne of the Later Zhou dynasty and went on to conquer the rest of the Ten Kingdoms, ending the Five Dynasties and Ten Kingdoms period. The Song often came into conflict with the contemporaneous Liao, Western Xia and Jin dynasties in northern China. After retreating to southern China following attacks by the Jin dynasty, the Song was eventually conquered by the Mongol-led Yuan dynasty.
The dynasty's history is divided into two periods: during the Northern Song (北宋; 960–1127), the capital was in the northern city of Bianjing (now Kaifeng) and the dynasty controlled most of what is now East China. The Southern Song (南宋; 1127–1279) comprise the period following the loss of control over the northern half of Song territory to the Jurchen-led Jin dynasty in the Jin–Song wars. At that time, the Song court retreated south of the Yangtze and established its capital at Lin'an (now Hangzhou). Although the Song dynasty had lost control of the traditional Chinese heartlands around the Yellow River, the Southern Song Empire contained a large population and productive agricultural land, sustaining a robust economy. In 1234, the Jin dynasty was conquered by the Mongols, who took control of northern China, maintaining uneasy relations with the Southern Song. Möngke Khan, the fourth Great Khan of the Mongol Empire, died in 1259 while besieging the mountain castle Diaoyucheng in Chongqing. His younger brother Kublai Khan was proclaimed the new Great Khan and in 1271 founded the Yuan dynasty. After two decades of sporadic warfare, Kublai Khan's armies conquered the Song dynasty in 1279 after defeating the Southern Song in the Battle of Yamen, and reunited China under the Yuan dynasty.

The River Parrett flows through the counties of Dorset and Somerset in South West England, from its source in the Thorney Mills springs in the hills around Chedington in Dorset. Flowing northwest through Somerset and the Somerset Levels to its mouth at Burnham-on-Sea, into the Bridgwater Bay nature reserve on the Bristol Channel, the Parrett and its tributaries drain an area of 660 square miles (1,700 km2) – about 50 per cent of Somerset's land area, with a population of 300,000.
The Parrett's main tributaries include the Rivers Tone, Isle, and Yeo, and the River Cary via the King's Sedgemoor Drain. The 37-mile (60 km) long river is tidal for 19 miles (31 km) up to Oath. Between Langport and Bridgwater, the river falls only 1 foot per mile (0.2 m/km), so it is prone to frequent flooding in winter and during high tides. Many approaches have been tried since at least the medieval period to reduce the incidence and effect of floods and to drain the surrounding fields. (Full article...) -
The Pali-Aike volcanic field is a volcanic field along the Argentina–Chile border. It is part of a family of back-arc volcanoes in Patagonia, which formed from processes involving the collision of the Chile Ridge with the Peru–Chile Trench. It lies farther east than the Austral Volcanic Zone, the volcanic arc that makes up the Andean Volcanic Belt at this latitude. Pali-Aike formed over sedimentary rock of Magallanes Basin, a Jurassic-age basin starting from the late Miocene as a consequence of regional tectonic events.
The volcanic field consists of an older plateau basalt formation and younger volcanic centres in the form of pyroclastic cones, scoria cones, maars and associated lava flows. There are approximately 467 vents in an area of 4,500 square kilometres (1,700 square miles). The vents often form local alignments along lineaments or faults, and there are a number of maars and other lakes, both volcanic and non-volcanic. The volcanic field is noteworthy for the presence of large amounts of xenoliths in its rocks and because the maar Potrok Aike is located here, where palaeoclimate data have been obtained. The field was active starting from 3.78 million years ago. The latest eruptions occurred during the Holocene, as indicated by the burial of archaeological artifacts; the Laguna Azul maar formed about 3,400 years before present. (Full article...) -
Roxy Ann Peak, also known as Roxy Ann Butte, is a 3,576-foot-tall (1,090 m) mountain in the Western Cascade Range at the eastern edge of Medford, Oregon. Composed of several geologic layers, the majority of the peak is of volcanic origin and dates to the early Oligocene epoch. It is primarily covered by oak savanna and open grassland on its lower slopes, and mixed coniferous forest on its upper slopes and summit, stopping short of the summit. Despite the peak's relatively small topographic prominence of 753 feet (230 m), it rises 2,200 feet (670 m) above Medford and is visible from most of the Rogue Valley. The mountain is Medford's most important viewshed, open space reserve, and recreational resource.
The area was originally inhabited beginning 8,000 to 10,000 years ago by ancestral Native Americans. The Latgawa Native American tribe was present in the early 1850s when the sudden influx of non-indigenous settlers resulted in the Rogue River Wars. After the wars, the Latgawa were forced away from the region onto reservations. The peak was named in August 1853 by immigrants arriving from Missouri via the Oregon Trail. Roxy Ann Hutchinson Hughes Bowen was the (step)grandmother of the McKee-Bowen family. Her step-daughter Maryum Bowen and Maryum's husband John McKee settled on, and filed a Donation Land Claim for, 320 acres on the SW flank of the butte (today's Hillcrest Orchards and Roxy Ann Vineyards).

Africa is the world's second-largest and second-most populous continent after Asia. At about 30.3 million km2 (11.7 million square miles) including adjacent islands, it covers 20% of Earth's land area and 6% of its total surface area. With nearly 1.4 billion people as of 2021, it accounts for about 18% of the world's human population. Africa's population is the youngest among all the continents; the median age in 2012 was 19.7, when the worldwide median age was 30.4. Based on 2024 projections, Africa's population will reach 3.8 billion people by 2099. Africa is the least wealthy continent per capita and second-least wealthy by total wealth, ahead of Oceania. Scholars have attributed this to different factors including geography, climate, corruption, colonialism, the Cold War, and neocolonialism. Despite this low concentration of wealth, recent economic expansion and a large and young population make Africa an important economic market in the broader global context. Africa has a large quantity of natural resources and food resources, including diamonds, sugar, salt, gold, iron, cobalt, uranium, copper, bauxite, silver, petroleum, natural gas, cocoa beans, and.

A composite relief satellite image of South America, the fourth-largest continent. South America occupies the southern portion of the landmass in the Western Hemisphere. The continent is generally 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, as do nearby outlying islands. -
Map credit: Central Intelligence AgencyThe Robinson projection is a projection of a world map showing the entire Earth at once. It was specifically created in an attempt to find a good compromise to the problem of showing the whole globe as a single flat image. The projection was devised by Arthur H. Robinson in 1963; distortion is severe close to the poles, but quickly declines to moderate levels as latitudes decrease. This Robinson-projection map, with standard parallels of 38°N and 38°S, was produced by the United States Central Intelligence Agency and shows the world as of February 2016. -
Photograph credit: European Space Agency / Sentinel-2The Yukon Delta is a river delta formed by the Yukon River as it drains into the Bering Sea. It is part of the larger Yukon–Kuskokwim Delta, which includes the delta of the Kuskokwim River. The Yukon River rises in British Columbia, Canada, and flows through Yukon before entering the U.S. state of Alaska. This August 2017 satellite image of the Yukon Delta shows how the river branches into numerous distributary channels that meander through the low-lying terrain on their way to the sea. The sandy colour of these channels and the coastal water is indicative of the marine sediment the river carries to the sea at this time of year. -
Map: Strebe, using GeocartThe Aitoff projection is a modified azimuthal map projection first proposed by David A. Aitoff in 1889. Based on the equatorial form of the azimuthal equidistant projection, Aitoff halved longitudes from the central meridian, projected by the azimuthal equidistant, and then stretched the result horizontally into a 2:1 ellipse. -
Map: Diego Gutiérrez and Hieronymus CockAmericae Sive Quartae Orbis Partis Nova Et Exactissima Descriptio is an ornate geographical map of the Americas made in 1562 by Spanish cartographer Diego Gutiérrez and Flemish artist Hieronymus Cock. The map encompasses the eastern coast of North America, the whole of Central and South America, and parts of the western coasts of Europe and Africa. This is the earliest scale wall map of the New World and the first to use the name "California". Two extant copies are known. -
Map: Strebe, using GeocartThe Chamberlin trimetric projection is a map projection where three points are fixed on the globe and the points on the sphere are mapped onto a plane by triangulation. It was developed in 1946 by Wellman Chamberlin for the National Geographic Society. It is neither conformal nor equal-area, but rather attempts to minimize distortion of distances everywhere with the side-effect of balancing between areal equivalence and conformality. -
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. -
Map: Strebe, using GeocartThe Gall–Peters projection, named after James Gall and Arno Peters, is a specialization of a configurable equal-area map projection known as the cylindrical equal-area projection. It achieved considerable notoriety in the late 20th century as the centerpiece of a controversy surrounding the political implications of map design; Peters promoted it as a more faithful representation than the Mercator projection, which inflates the sizes of regions farther from the equator and thus makes the (mostly technologically underdeveloped) equatorial countries appear smaller and therefore, according to Peters, less significant. -
Typhoon Noru was the second-longest lasting tropical cyclone of the northwest Pacific Ocean on record. The fifth named storm of the 2017 Pacific typhoon season, it formed on July 19 and reached peak intensity on July 31 with 175 km/h (110 mph) 10-minute sustained winds. By this time, as shown in this satellite image, the typhoon was located south of Iwo Jima, and had taken on annular characteristics, with a symmetric ring of deep convection surrounding a 30 km (19 mi) well defined eye and fairly uniform cloud top temperatures. Traveling northwestward over an area of low ocean heat content, the eye became enlarged and ragged as the system weakened. By the time Noru made landfall over Wakayama Prefecture, Japan, on August 7, it had been downgraded to a severe tropical storm. It then dissipated over the Sea of Japan on August 9 as an extratropical cyclone. -
Map: Strebe, using GeocartThe Mercator projection is a cylindrical map projection presented by the Flemish geographer and cartographer Gerardus Mercator in 1569. Because it represents paths of constant course as straight lines, it long served as the standard map projection for nautical purposes. However, it distorts the size of objects as the latitude increases: thus areas in the mid-latitudes appear significantly larger than their actual size relative to those the equator, and those near the poles are even more exaggerated. Most modern atlases no longer use the Mercator projection for world maps or for areas distant from the equator, preferring other cylindrical projections, or forms of equal-area projection. -
A map of the Olmec heartland, the southern portion of Mexico's Gulf Coast region between the Tuxtla mountains and the Olmec archaeological site of La Venta. It is considered the heartland of the Olmec culture, which was widespread over Mesoamerica from 1400 BCE until roughly 400 BCE.
On this map, yellow dots represent ancient habitation sites, including San Lorenzo Tenochtitlán, La Venta, and Tres Zapotes. Red dots represent isolated artifact finds unassociated with any ancient town or village, such as the Las Limas Monument 1, the San Martín Pajapan Monument 1, and "The Wrestler". -
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. -
Author: John Mitchell; scan: Library of Congress, Geography and Map Division.The Mitchell Map is the most comprehensive map of eastern North America made during the colonial era. Measuring about 6.5 ft (2.0 m) wide by 4.5 ft (1.4 m) high, it was produced by John Mitchell in 1757 in eight separate sheets. The map was used during the Treaty of Paris for defining the boundaries of the United States, and remains important today for resolving border disputes. -
Map: Strebe, using GeocartThe Kavrayskiy VII projection is a map projection invented by Vladimir V. Kavrayskiy in 1939 as a general purpose pseudocylindrical projection. It produces maps with low overall distortion, despite its straight, evenly-spaced parallels and a simple formulation. -
Photograph: Maull & Fox; restoration: Adam CuerdenFanny Bullock Workman (1859–1925) was an American geographer, cartographer, explorer, travel writer, and mountaineer. Together with her husband, William Hunter Workman, she traveled by bicycle through Switzerland, France, Italy, Spain, Algeria and India; after taking up climbing in the Himalayas, she set a women's altitude record on Pinnacle Peak, reaching 23,000 feet (7,000 m). She published eight travel books, with particular focus on the lives of women in the countries she visited, and championed women's rights and women's suffrage.

Daniel Boone (November 2 [O.S. October 22], 1734 – September 26, 1820) was an American pioneer and frontiersman whose exploits made him one of the first folk heroes of the United States. He became famous for his exploration and settlement of Kentucky, which was then beyond the western borders of the Thirteen Colonies. In 1775, Boone founded the Wilderness Road through the Cumberland Gap and into Kentucky, despite resistance from Native Americans. He founded Boonesborough, one of the first English-speaking settlements west of the Appalachian Mountains. By the end of the 18th century, more than 200,000 people had entered Kentucky by following the route marked by Boone.
Boone served as a militia officer during the Revolutionary War (1775–1783), which was fought in Kentucky primarily between American settlers and British-allied Indians. Boone was taken in by Shawnees in 1778 and adopted into the tribe, but he resigned and continued to help protect the Kentucky settlements. He also left due to the Shawnee Indians torturing and killing one of his sons. He was elected to the first of his three terms in the Virginia General Assembly during the war and fought in the Battle of Blue Licks in 1782, one of the last battles of the American Revolution. He worked as a surveyor and merchant after the war, but went deep into debt as a Kentucky land speculator. He resettled in Missouri in 1799, where he spent most of the last two decades of his life, frustrated with legal problems resulting from his land claims. (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.

Earth is the third planet from the Sun and the only astronomical object known to harbor life. This is enabled by Earth being an ocean world, the only one in the Solar System sustaining liquid surface water. Almost all of Earth's water is contained in its global ocean, covering 70.8% of Earth's crust. The remaining 29.2% of Earth's crust is land, most of which is located in the form of continental landmasses within Earth's land hemisphere. Most of Earth's land is somewhat humid and covered by vegetation, while large sheets of ice at Earth's polar deserts retain more water than Earth's groundwater, lakes, rivers and atmospheric water combined. Earth's crust consists of slowly moving tectonic plates, which interact to produce mountain ranges, volcanoes, and earthquakes. Earth has a liquid outer core that generates a magnetosphere capable of deflecting most of the destructive solar winds and cosmic radiation. (Full article...) -

London is the capital and largest city of both England and the United Kingdom, with a population of 8,866,180 in 2022. The wider metropolitan area is the largest in Western Europe, with a population of 14.9 million. London stands on the River Thames in southeast England, at the head of a 50-mile (80 km) estuary down to the North Sea, and has been a major settlement for nearly 2,000 years. Its ancient core and financial centre, the City of London, was founded by the Romans as Londinium and has retained its medieval boundaries. The City of Westminster, to the west of the City of London, has been the centuries-long host of the national government and parliament. London grew rapidly in the 19th century, becoming the world's largest city at the time. Since the 19th century, the name "London" has referred to the metropolis around the City of London, historically split between the counties of Middlesex, Essex, Surrey, Kent, and Hertfordshire, which since 1965 has largely comprised the administrative area of Greater London, governed by 33 local authorities and the Greater London Authority.
