Bryce Canyon National Park (/braɪs/) is an American national park located in southwestern Utah. The major feature of the park is Bryce Canyon, which despite its name, is not a canyon, but a collection of giant natural amphitheaters along the eastern side of the Paunsaugunt Plateau. Bryce is distinctive due to geological structures called hoodoos, formed by frost weathering and stream erosion of the river and lake bed sedimentary rocks. The red, orange, and white colors of the rocks provide spectacular views for park visitors. Bryce Canyon National Park is much smaller and sits at a much higher elevation than nearby Zion National Park. The rim at Bryce varies from 8,000 to 9,000 feet (2,400 to 2,700 m).

The Bryce Canyon area was settled by Mormon pioneers in the 1850s and was named after Ebenezer Bryce, who homesteaded in the area in 1874. The area around Bryce Canyon was originally designated as a national monument by President Warren G. Harding in 1923 and was redesignated as a national park by Congress in 1928. The park covers 35,835 acres (55.992 sq mi; 14,502 ha; 145.02 km²) and receives substantially fewer visitors than Zion National Park (nearly 4.3 million in 2016) or Grand Canyon National Park (nearly 6 million in 2016), largely due to Bryce's more remote location. In 2018, Bryce Canyon received 2,679,478 recreational visitors, which was an increase of 107,794 visitors from the prior year. (Full article...)

The castle's enclosure and keep

Warkworth Castle is a ruined medieval castle in Warkworth in the English county of Northumberland. The village and castle occupy a loop of the River Coquet, less than a mile from England's north-east coast. When the castle was founded is uncertain: traditionally its construction has been ascribed to Prince Henry of Scotland, Earl of Northumbria, in the mid-12th century, but it may have been built by King Henry II of England when he took control of England's northern counties. Warkworth Castle was first documented in a charter of 1157–1164 when Henry II granted it to Roger fitz Richard. The timber castle was considered "feeble", and was left undefended when the Scots invaded in 1173.

Roger's son Robert inherited and improved the castle. Robert was a favourite of King John, and hosted him at Warkworth Castle in 1213. The castle remained in the family line, with periods of guardianship when heirs were too young to control their estates. King Edward I stayed overnight in 1292 and John de Clavering, descendant of Roger fitz Richard, made the Crown his inheritor. With the outbreak of the Anglo-Scottish Wars, Edward II invested in castles, including Warkworth, where he funded the strengthening of the garrison in 1319. Twice in 1327 the Scots besieged the castle without success. (Full article...)

Farming at Carrington Moss

Carrington Moss is a large area of peat bog near Carrington, Greater Manchester, England, south of the River Mersey, 10 miles (16 km) south-west of Manchester. It occupies an area of about 1,100 acres (450 ha). The depth of peat varies between 17 and 20 feet (5.2 and 6.1 m).

Originally an unused area of grouse moorland, the moss was reclaimed in the latter half of the 19th century for farming and the disposal of Manchester's waste. A system of tramways was built to connect it with the Manchester Ship Canal and a nearby railway line. In the Second World War, the land was used as a Starfish site and in the latter half of the 20th century a large industrial complex was built along its northern edge. More recently, several sporting facilities have been built on Carrington Moss. (Full article...)

Rogue River from Hellgate Canyon

The Rogue River (Tolowa: yan-shuu-chit’ taa-ghii~-li~’, Takelma: tak-elam) in southwestern Oregon in the United States flows about 215 miles (346 km) in a generally westward direction from the Cascade Range to the Pacific Ocean. Known for its salmon runs, whitewater rafting, and rugged scenery, it was one of the original eight rivers named in the Wild and Scenic Rivers Act of 1968. Beginning near Crater Lake, which occupies the caldera left by the explosive volcanic eruption and collapse of Mount Mazama, the river flows through the geologically young High Cascades and the older Western Cascades, another volcanic province. Further west, the river passes through multiple exotic terranes of the more ancient Klamath Mountains. In the Kalmiopsis Wilderness section of the Rogue basin are some of the world's best examples of rocks that form the Earth's mantle. Near the mouth of the river, the only dinosaur fragments ever discovered in Oregon were found in the Otter Point Formation, along the coast of Curry County.

People have lived along the Rogue River and its tributaries for at least 8,500 years. European explorers made first contact with Native Americans (Indians) toward the end of the 18th century and began beaver trapping and other activities in the region. Clashes, sometimes deadly, occurred between the natives and the trappers and later between the natives and European-American miners and settlers. These struggles culminated with the Rogue River Wars of 1855–56 and removal of most of the natives to reservations outside the basin. After the war, settlers expanded into remote areas of the watershed and established small farms along the river between Grave Creek and the mouth of the Illinois River. They were relatively isolated from the outside world until 1895, when the Post Office Department added mail boat service along the lower Rogue. As of 2010, the Rogue has one of the two remaining rural mail-boat routes in the United States. (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.

Pine Creek flows through the park and has carved the gorge through five major rock formations from the Devonian and Carboniferous periods. Native Americans once used the Pine Creek Path along the creek. The path was later used by lumbermen, and then became the course of a railroad from 1883 to 1988. Since 1996, the 62-mile (100 km) Pine Creek Rail Trail has followed the creek through the gorge. The Pine Creek Gorge was named a National Natural Landmark in 1968 and is also protected as a Pennsylvania State Natural Area and Important Bird Area, while Pine Creek is a Pennsylvania Scenic and Wild River. The gorge is home to many species of plants and animals, some of which have been reintroduced to the area. (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. The largest was the Tule Lake internment camp, located in northern California with a population of over 18,000 inmates. The smallest was Amanche, located southeastern Colorado, with over 7,000 inmates. 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 of 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.

Columbia Slough near mouth

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...)

The drift of the Antarctic exploration vessel SY Aurora was an ordeal which lasted 312 days, affecting the Ross Sea party of Sir Ernest Shackleton's Imperial Trans-Antarctic Expedition, 1914–1917. It began when the ship broke loose from its anchorage in McMurdo Sound in May 1915, during a gale. Caught in heavy pack ice and unable to manoeuvre, Aurora, with eighteen men aboard, was carried into the open waters of the Ross Sea and Southern Ocean, leaving ten men stranded ashore with meagre provisions.

Aurora, a 40-year-old former Arctic whaler registered as a steam yacht, had brought the Ross Sea party to Cape Evans in McMurdo Sound in January 1915, to establish its base there in support of Shackleton's proposed transcontinental crossing. When Aurora's captain Aeneas Mackintosh took charge of activities ashore, first officer Joseph Stenhouse assumed command of the ship. Stenhouse's inexperience may have contributed to the choice of an inappropriate winter's berth, although his options were restricted by the instructions of his superiors. After the ship was blown away it suffered severe damage in the ice, including the destruction of its rudder and the loss of its anchors; on several occasions its situation was such that Stenhouse considered abandonment. Efforts to make wireless contact with Cape Evans and, later, with stations in New Zealand and Australia, were unavailing; the drift extended through the southern winter and spring to reach a position north of the Antarctic Circle. In February 1916 the ice broke up, and a month later the ship was free. It was subsequently able to reach New Zealand for repairs and resupply, before returning to Antarctica to rescue the seven surviving members of the shore party. (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. A number of 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...)

Combined visible/near-IR/shortwave-IR satellite image of Quelccaya in 2010; snow and ice appear as light blue or cyan.

The Quelccaya Ice Cap (also known as Quenamari Ice Cap) is the second largest glaciated area in the tropics, after Coropuna. Located in the Cordillera Oriental section of the Andes mountains in Peru, the cap covers an area of 42.8 square kilometres (16.5 sq mi) with ice up to 200 metres (660 ft) thick. It is surrounded by tall ice cliffs and a number of outlet glaciers, the largest of which is known as Qori Kalis Glacier; lakes, moraines, peat bogs and wetlands are also present. There is a rich flora and fauna, including birds that nest on the ice cap. Quelccaya is an important source of water, eventually melting and flowing into the Inambari and Vilcanota Rivers.

A number of ice cores have been obtained from Quelccaya, including two from 1983 that were the first recovered outside of the polar regions. Past climate states have been reconstructed from data in these ice cores; these include evidence of the Little Ice Age, regional droughts and wet periods with historical significance and past and recent El Niño events. The ice cap is regularly monitored and has a weather station. (Full article...)

Sale Town Hall

Sale is a town in Trafford, Greater Manchester, England, in the historic county of Cheshire on the south bank of the River Mersey, 2 miles (3.2 km) south of Stretford, 3 miles (4.8 km) northeast of Altrincham, and 5 miles (8.0 km) southwest of Manchester. In 2011, it had a population of 134,022, making it the largest town by population in Trafford.

Evidence of Stone Age, Roman and Anglo-Saxon activity has previously been discovered locally. In the Middle Ages, Sale was a rural township, linked ecclesiastically with neighbouring Ashton upon Mersey, whose fields and meadows were used for crop and cattle farming. By the 17th century, Sale had a cottage industry manufacturing garthweb, the woven material from which horses' saddle girths were made. (Full article...)

The north fork of Little Butte Creek

Little Butte Creek is a 17-mile-long (27 km) tributary of the Rogue River in the U.S. state of Oregon. Its drainage basin consists of approximately 354 square miles (917 km²) of Jackson County and another 19 square miles (49 km²) of Klamath County. Its two forks, the North Fork and the South Fork, both begin high in the Cascade Range near Mount McLoughlin and Brown Mountain. They both flow generally west until they meet near Lake Creek. The main stem continues west, flowing through the communities of Brownsboro, Eagle Point, and White City, before finally emptying into the Rogue River about 3 miles (5 km) southwest of Eagle Point.

Little Butte Creek's watershed was originally settled by the Takelma, and possibly the Shasta tribes of Native Americans. In the Rogue River Wars of the 1850s, most of the Native Americans were either killed or forced onto Indian reservations. Early settlers named Little Butte Creek and nearby Big Butte Creek after their proximity to Mount McLoughlin, which was known as Snowy Butte. In the late 19th century, the watershed was primarily used for agriculture and lumber production. The city of Eagle Point was incorporated in 1911, and remains the only incorporated town within the watershed's boundaries. (Full article...)

Kigali (Kinyarwanda pronunciation: [ci.ɡɑ́.ɾi]) is the capital and largest city of Rwanda. It is near the nation's geographic centre in a region of rolling hills, with a series of valleys and ridges joined by steep slopes. As a primate city, Kigali has been Rwanda's economic, cultural, and transport hub since it became the capital following independence from Belgian rule in 1962.

In an area controlled by the Kingdom of Rwanda from the 17th century and then by the German Empire, the city was founded in 1907 when Richard Kandt, the colonial resident, chose the site for his headquarters, citing its central location, views and security. Foreign merchants began to trade in the city during the German era, and Kandt opened some government-run schools for Tutsi Rwandan students. Belgium took control of Rwanda and Burundi during World War I, forming the mandate of Ruanda-Urundi. Kigali remained the seat of colonial administration for Rwanda but Ruanda-Urundi's capital was at Usumbura (now Bujumbura) in Burundi and Kigali remained a small city with a population of just 6,000 at the time of independence.

Title page of the first edition of Wright's Certaine Errors in Navigation (1599)

Edward Wright (baptised 8 October 1561; died November 1615) was an English mathematician and cartographer noted for his book Certaine Errors in Navigation (1599; 2nd ed., 1610), which for the first time explained the mathematical basis of the Mercator projection by building on the works of Pedro Nunes, and set out a reference table giving the linear scale multiplication factor as a function of latitude, calculated for each minute of arc up to a latitude of 75°. This was in fact a table of values of the integral of the secant function, and was the essential step needed to make practical both the making and the navigational use of Mercator charts.

Wright was born at Garveston in Norfolk and educated at Gonville and Caius College, Cambridge, where he became a fellow from 1587 to 1596. In 1589 the college granted him leave after Elizabeth I requested that he carry out navigational studies with a raiding expedition organised by the Earl of Cumberland to the Azores to capture Spanish galleons. The expedition's route was the subject of the first map to be prepared according to Wright's projection, which was published in Certaine Errors in 1599. The same year, Wright created and published the first world map produced in England and the first to use the Mercator projection since Gerardus Mercator's original 1569 map. (Full article...)

Before drainage, the Everglades, a region of tropical wetlands in southern Florida, were an interwoven mesh of marshes and prairies covering 4,000 square miles (10,000 km²). The Everglades is both a vast watershed that has historically extended from Lake Okeechobee 100 miles (160 km) south to Florida Bay (around one-third of the southern Florida peninsula), and many interconnected ecosystems within a geographic boundary. It is such a unique meeting of water, land, and climate that the use of either singular or plural to refer to the Everglades is appropriate. When Marjory Stoneman Douglas wrote her definitive description of the region in 1947, she used the metaphor "River of Grass" to explain the blending of water and plant life.

Although sawgrass and sloughs are the enduring geographical icons of the Everglades, other ecosystems are just as vital, and the borders marking them are subtle or nonexistent. Pinelands and tropical hardwood hammocks are located throughout the sloughs; the trees, rooted in soil inches above the peat, marl, or water, support a variety of wildlife. The oldest and tallest trees are cypresses, whose roots are specially adapted to grow underwater for months at a time. The Big Cypress Swamp is well known for its 500-year-old cypresses, though cypress domes can appear throughout the Everglades. As the freshwater from Lake Okeechobee makes its way to Florida Bay, it meets saltwater from the Gulf of Mexico; mangrove forests grow in this transitional zone, providing nursery and nesting conditions for many species of birds, fish, and invertebrates. The marine environment of Florida Bay is also considered part of the Everglades because its seagrasses and aquatic life are attracted to the constant discharge of freshwater. (Full article...)

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 is represented by 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 of 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.

Clockwise from top: City of London in the foreground with Canary Wharf in the far background; Trafalgar Square; London Eye; Tower Bridge; and a London Underground roundel in front of Elizabeth Tower

London is the capital and largest city of England and the United Kingdom, with a population of just under 9 million. It stands on the River Thames in south-east England at the head of a 50-mile (80 km) estuary down to the North Sea, and has been a major settlement for two millennia. The City of London, its ancient core and financial centre, was founded by the Romans as Londinium and retains its medieval boundaries. The City of Westminster, to the west of the City of London, has for centuries hosted the national government and parliament. Since the 19th century, the name "London" has also referred to the metropolis around this core, historically split between the counties of Middlesex, Essex, Surrey, Kent, and Hertfordshire, which since 1965 has largely comprised Greater London, which is governed by 33 local authorities and the Greater London Authority.

Earth is the third planet from the Sun and the only place known in the universe where life has originated and found habitability. While Earth may not contain the largest volumes of water in the Solar System, only Earth sustains liquid surface water, extending over 70.8% of the Earth with its ocean, making Earth an ocean world. Earth's polar regions currently retain most of all other water with large sheets of ice covering ocean and land, dwarfing Earth's groundwater, lakes, rivers and atmospheric water. Land, consisting of continents and islands, extends over 29.2% of the Earth and is widely covered by vegetation. Below Earth's surface material lies Earth's crust consisting of several slowly moving tectonic plates, which interact to produce mountain ranges, volcanoes, and earthquakes. Earth's liquid outer core generates a magnetic field that shapes the magnetosphere of Earth, largely deflecting destructive solar winds and cosmic radiation. (Full article...)

Millennials, also known as Generation Y or Gen Y, are the demographic cohort following Generation X and preceding Generation Z.
