The North America Portal

North America is a continent in the Northern and Western Hemispheres. North America is bordered to the north by the Arctic Ocean, to the east by the Atlantic Ocean, to the southeast by South America and the Caribbean Sea, and to the west and south by the Pacific Ocean. The region includes the Bahamas, Bermuda, Canada, the Caribbean, Central America, Clipperton Island, Greenland, Mexico, Saint Pierre and Miquelon, Turks and Caicos Islands, and the United States.

North America covers an area of about 24,709,000 square kilometers (9,540,000 square miles), representing approximately 16.5% of the Earth's land area and 4.8% of its total surface area. It is the third-largest continent by size after Asia and Africa, and the fourth-largest continent by population after Asia, Africa, and Europe. , North America's population was estimated as over 592 million people in 23 independent states, or about 7.5% of the world's population. In human geography, the terms "North America" and "North American" sometimes refer to just Canada, the United States, Mexico, and Greenland.

It is unknown with certainty how and when first human populations first reached North America. People were known to live in the Americas at least 20,000 years ago, but various evidence points to possibly earlier dates. The Paleo-Indian period in North America followed the Last Glacial Period, and lasted until about 10,000 years ago when the Archaic period began. The classic stage followed the Archaic period, and lasted from approximately the 6th to 13th centuries. Beginning in 1000 AD, the Norse were the first Europeans to begin exploring and ultimately colonizing areas of North America.

In 1492, the exploratory voyages of Christopher Columbus led to a transatlantic exchange, including migrations of European settlers during the Age of Discovery and the early modern period. Present-day cultural and ethnic patterns reflect interactions between European colonists, indigenous peoples, enslaved Africans, immigrants from Europe, Asia, and descendants of these respective groups.

Visitors descend the downstream side of Dam 1 on the Bull Run River.

The Bull Run River is a 21.9-mile (35.2 km) tributary of the Sandy River in the U.S. state of Oregon. Beginning at the lower end of Bull Run Lake in the Cascade Range, it flows generally west through the Bull Run Watershed Management Unit (BRWMU), a restricted area meant to protect the river and its tributaries from contamination. The river, impounded by two artificial storage reservoirs as well as the lake, is the primary source of drinking water for the city of Portland, Oregon.

It is likely that Native Americans living along the Columbia River as early as 10,000 years ago visited the Bull Run watershed in search of food. Within the past few thousand years they created trails over the Cascade Range and around Mount Hood, near the upper part of the Bull Run watershed. By the mid-19th century, pioneers used these trails to cross the mountains from east to west to reach the fertile Willamette Valley. In the 1890s, the City of Portland, searching for sources of clean drinking water, chose the Bull Run River. Dam-building, road construction, and legal action to protect the watershed began shortly thereafter, and Bull Run water began to flow through a large pipe to the city in 1895. (Full article...)

Zappa performing at Ekeberghallen in Oslo, Norway, in 1977

Frank Vincent Zappa (/ˈzæpə/ ZAP; December 21, 1940 – December 4, 1993) was an American musician, composer, and bandleader. In a career spanning more than 30 years, Zappa composed rock, pop, jazz, jazz fusion, orchestral and musique concrète works; he also produced almost all of the 60-plus albums that he released with his band the Mothers of Invention and as a solo artist. His work is characterized by nonconformity, improvisation sound experimentation, musical virtuosity and satire of American culture. Zappa also directed feature-length films and music videos, and designed album covers. He is considered one of the most innovative and stylistically diverse musicians of his generation.

As a mostly self-taught composer and performer, Zappa had diverse musical influences that led him to create music that was sometimes difficult to categorize. While in his teens, he acquired a taste for 20th-century classical modernism, African-American rhythm and blues, and doo-wop music. He began writing classical music in high school, while simultaneously playing drums in rhythm and blues bands, later switching to electric guitar. His debut studio album with the Mothers of Invention, Freak Out! (1966), combined satirical but seemingly conventional rock and roll songs with extended sound collages. He continued this eclectic and experimental approach throughout his career. (Full article...)

The final offensive of 1981 (Spanish: ofensiva final de 1981), also known as the general offensive of 1981 (Spanish: ofensiva general de 1981), was the unsuccessful first military offensive conducted by the Farabundo Martí National Liberation Front (FMLN) during the Salvadoran Civil War. The objective of the offensive was to initiate a popular revolution to overthrow the Revolutionary Government Junta (JRG), which had been ruling the country since the 1979 Salvadoran coup d'état. The FMLN hoped that the government would be overthrown by 20 January 1981; the date Ronald Reagan was to be inaugurated as president of the United States.

During the first phase of the offensive from 10 to 17 January, the FMLN carried out attacks across northern and western El Salvador, incited a general strike across the nation, a military mutiny in the second largest city, Santa Ana, and secured several important cities and villages. During the second phase from 18 to 26 January, the FMLN began, what they termed, a "temporary tactical retreat" as government forces began to recapture previously lost territory. The offensive ended in a military defeat for the FMLN, but it solidified the group as an effective fighting force. (Full article...)
