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...)

Southern right whale breaching
Right whales are three species of large baleen whales of the genusEubalaena: 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...)
Ann Arbor was founded in 1824 by John Allen and Elisha Rumsey. It was named after the wives of the village's founders, both named Ann, and the stands of bur oak trees they found at the site of the town. The University of Michigan was established in Ann Arbor in 1837, and the city's population grew at a rapid rate in the early to mid-20th century. (Full article...)
The Columbia Slough is a narrow waterway, about 19 miles (31 km) long, in the floodplain of the Columbia River in the U.S. state of Oregon. From its source in the Portland suburb of Fairview, the Columbia Slough meanders west through Gresham and Portland to the Willamette River, about 1 mile (1.6 km) from the Willamette's confluence with the Columbia. It is a remnant of the historic wetlands between the mouths of the Sandy River to the east and the Willamette River to the west. Levees surround much of the main slough as well as many side sloughs, detached sloughs, and nearby lakes. Drainage district employees control water flows with pumps and floodgates. Tidal fluctuations cause reverse flow on the lower slough.
The Columbia floodplain, formed by geologic processes including lava flows, volcanic eruptions, and the Missoula Floods, is part of the Portland Basin, which extends across the Columbia River from Multnomah County, Oregon, into Clark County, Washington. Five percent of Oregon's population, about 158,000 people, live in the slough watershed of about 51 square miles (130 km2). Municipal wells near the upper slough provide supplemental drinking water to Portland and nearby cities. The cities, the drainage districts, the county, and a regional government, Metro, have overlapping jurisdictions in the watershed. A regional agency operates Portland International Airport along the middle slough and marine terminals near the lower slough. The Oregon Department of Environmental Quality (DEQ) and the city's Bureau of Environmental Services (BES) deal with environmental issues. (Full article...)

CCC-built overlook looking south into the Pine Creek Gorge in Colton Point State Park
Colton Point State Park is a 368-acre (149 ha) Pennsylvania state park in Tioga County, Pennsylvania, in the United States. It is on the west side of the Pine Creek Gorge, also known as the Grand Canyon of Pennsylvania, which is 800 feet (240 m) deep and nearly 4,000 feet (1,200 m) across at this location. The park extends from the creek in the bottom of the gorge up to the rim and across part of the plateau to the west. Colton Point State Park is known for its views of the Pine Creek Gorge, and offers opportunities for picnicking, hiking, fishing and hunting, whitewater boating, and camping. Colton Point is surrounded by Tioga State Forest and its sister park, Leonard Harrison State Park, on the east rim. The park is on a state forest road in Shippen Township 5 miles (8 km) south of U.S. Route 6.
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...)
Historians generally consider the battle as among Frederick's greatest blunders. Contrary to the advice of his subordinates, he refused to believe that the typically cautious Austrian commander Leopold von Daun would bring his troops into battle. The Austrian force ambushed his army in a pre-dawn attack. Over 30% of Frederick's army was defeated; five generals were killed, and he lost his artillery park and a vast quantity of supplies. Although Daun had scored a complete surprise, his attempt to pursue the retreating Prussians was unsuccessful. The escaped force united with another corps in the vicinity and regained momentum over the winter. (Full article...)

The Three Sisters, looking north
The Three Sisters are closely spaced volcanic peaks in the U.S. state of Oregon. They are part of the Cascade Volcanic Arc, a segment of the Cascade Range in western North America extending from southern British Columbia through Washington and Oregon to Northern California. Each over 10,000 feet (3,000 meters) in elevation, they are the third-, fourth- and fifth-highest peaks in Oregon. Located in the Three Sisters Wilderness at the boundary of Lane and Deschutes counties and the Willamette and Deschutes national forests, they are about 10 miles (16 kilometers) south of the nearest town, Sisters. Diverse species of flora and fauna inhabit the area, which is subject to frequent snowfall, occasional rain, and extreme temperature variation between seasons. The mountains, particularly South Sister, are popular destinations for climbing and scrambling.
Although they are often grouped together as one unit, the three mountains have their own individual geology and eruptive history. Neither North Sister nor Middle Sister has erupted in the last 14,000 years, and it is considered unlikely that either will ever erupt again. South Sister last erupted about 2,000 years ago and could erupt in the future, threatening life within the region. After satellite imagery detected ground inflation near South Sister in 2001, the United States Geological Survey improved monitoring in the immediate area. (Full article...)

The Makassar kingdom of Gowa emerged around 1300 CE as one of many agrarian chiefdoms in the Indonesian peninsula of South Sulawesi. From the sixteenth century onward, Gowa and its coastal ally Talloq became the first powers to dominate most of the peninsula, following wide-ranging administrative and military reforms, including the creation of the first bureaucracy in South Sulawesi. The early history of the kingdom has been analyzed as an example of state formation.
Genealogies and archaeological evidence suggest that the Gowa dynasty was founded around 1300 in a marriage between a local woman and a chieftain of the Bajau, a nomadic maritime people. Early Gowa was a largely agrarian polity with no direct access to the coastline, whose growth was supported by a rapid increase in wet Asian rice cultivation. Talloq was founded two centuries later when a prince from Gowa fled to the coast after his defeat in a succession dispute. The coastal location of the new polity allowed it to exploit maritime trade to a greater degree than Gowa. (Full article...)

The United States and Denmark launched an intensive clean-up and recovery operation, but the secondary stage of one of the nuclear weapons could not be accounted for after the operation was completed. USAF Strategic Air Command "Chrome Dome" operations were discontinued immediately after the accident, which highlighted the safety and political risks of the missions. Safety procedures were reviewed, and more stable explosives were developed for use in nuclear weapons. (Full article...)

View of Mount Berlin from the surrounding ice sheet
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.

Cannon decorate the quayside of Balfour Harbour on Shapinsay, the round tower in the background is The Douche
Shapinsay (/ˈʃæpɪnziː/, Scots: Shapinsee) is one of the Orkney Islands off the north coast of mainland Scotland. With an area of 29.5 square kilometres (11.4 sq mi), it is the eighth largest island in the Orkney archipelago. It is low-lying and, with a bedrock formed from Old Red Sandstone overlain by boulder clay, fertile, causing most of the area to be used for farming. Shapinsay has two nature reserves and is notable for its bird life. Balfour Castle, built in the Scottish Baronial style, is one of the island's most prominent features, a reminder of the Balfour family's domination of Shapinsay during the 18th and 19th centuries; the Balfours transformed life on the island by introducing new agricultural techniques. Other landmarks include a standing stone, an Iron Agebroch, a souterrain and a salt-water shower.
There is one village on the island, Balfour, from which roll-on/roll-off car ferries sail to Kirkwall on the Orkney Mainland. At the 2011 census, Shapinsay had a population of 307. The economy of the island is primarily based on agriculture with the exception of a few small businesses that are largely tourism-related. A community-owned wind turbine was constructed in 2011. The island has a primary school but, in part due to improving transport links with mainland Orkney, no longer has a secondary school. Shapinsay's long history has given rise to various folk tales.

Production began in the mid-1970s as a faithful adaptation of the novella, following 1951's The Thing from Another World. The Thing went through several directors and writers, each with different ideas on how to approach the story. Filming lasted roughly twelve weeks, beginning in August 1981, and took place on refrigerated sets in Los Angeles as well as in Juneau, Alaska, and Stewart, British Columbia. Of the film's $15million budget, $1.5million was spent on Rob Bottin's creature effects, a mixture of chemicals, food products, rubber, and mechanical parts turned by his large team into an alien capable of taking on any form.

The war arose from the failure of the Truce of Nice, which ended the Italian War of 1536–1538, to resolve the long-standing conflict between Charles and Francis—particularly their conflicting claims to the Duchy of Milan. Having found a suitable pretext, Francis once again declared war against his perpetual enemy in 1542. Fighting began at once throughout the Low Countries; the following year saw the Franco-Ottoman alliance's attack on Nice, as well as a series of maneuvers in Northern Italy which culminated in the bloody Battle of Ceresole. Charles and Henry then proceeded to invade France, but the long sieges of Boulogne-sur-Mer and Saint-Dizier prevented a decisive offensive against the French. (Full article...)
The General Perspective projection is a map projection used in cartography in which the Earth is depicted as viewed from a finite distance above its surface. If the view precisely faces the center of the Earth, the projection is a vertical perspective projection; otherwise, it is a tilted perspective projection. Here is shown a vertical perspective from an altitude of 35,786 km over (0°, 90°W), corresponding to a view from geostationary orbit. Due to the horizon as seen from the viewpoint position, the projection always shows less than half of the Earth's surface: in this case neither of the North and South Poles is visible.
A satellite image of the Scandinavian Peninsula in winter. The peninsula, approximately 1,850 kilometers (1,150 miles) long with a width varying between approximately 370–805 km (230–500 mi), making it the largest in Europe, is located in the northern part of the continent and consists of Norway, Sweden and part of Finland. Much of the population is concentrated in the southern part of the peninsula; Stockholm and Gothenburg, both in Sweden, and Oslo in Norway are the largest cities.

The 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.
A composite satellite image of the geography of Africa, the Earth's second-largest continent, and its adjacent islands. Separated from Europe by the Mediterranean Sea and from much of Asia by the Red Sea, Africa is joined to Asia at its northeast extremity by the Isthmus of Suez. For geopolitical purposes, the Sinai Peninsula – east of the Suez Canal – is often considered part of Africa, although geographically it belongs in Asia. Africa can be divided into a number of geographic zones: The Atlas Mountains in the north, the Sahara, the coastal plains, and the inner plateaus.

Fanny 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.
The equirectangular projection is a simple map projection attributed to Marinus of Tyre, who Ptolemy claims invented the projection about AD 100. The projection maps meridians to vertical straight lines of constant spacing, and circles of latitude to horizontal straight lines of constant spacing. The projection is neither equal area nor conformal. Because of the distortions introduced by this projection, it has few applications beyond base imagery to be reprojected to some more useful projection.
The last picture ever taken of Johnston, 13 hours before his death at the eruption site
David Alexander Johnston (December 18, 1949 – May 18, 1980) was an American United States Geological Survey (USGS) volcanologist who was killed by the 1980 eruption of Mount St. Helens in the U.S. state of Washington. A principal scientist on the USGS monitoring team, Johnston was killed in the eruption while manning an observation post six miles (10 km) away on the morning of May 18, 1980. He was the first to report the eruption, transmitting "Vancouver! Vancouver! This is it!" before he was swept away by a lateral blast; despite a thorough search, Johnston's body was never found, but state highway workers discovered remnants of his USGS trailer in 1993.
Johnston's career took him across the United States, where he studied the Augustine Volcano in Alaska, the San Juan volcanic field in Colorado, and long-extinct volcanoes in Michigan. Johnston was a meticulous and talented scientist, known for his analyses of volcanic gases and their relationship to eruptions. This, along with his enthusiasm and positive attitude, made him liked and respected by many co-workers. After his death, other scientists lauded his character, both verbally and in dedications and letters. Johnston felt scientists must do what is necessary, including taking risks, to help protect the public from natural disasters. His work, and that of fellow USGS scientists, convinced authorities to close Mount St. Helens to the public before the 1980 eruption. They maintained the closure despite heavy pressure to re-open the area; their work saved thousands of lives. His story became intertwined with the popular image of volcanic eruptions and their threat to society, and a part of volcanology's history. To date, Johnston, along with his mentee Harry Glicken, is one of two American volcanologists known to have died in a volcanic eruption. (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.

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.
