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. Greater North America 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.

Continental 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, African slaves, immigrants from Europe, Asia, and descendants of these respective groups.

The Colorado River at Horseshoe Bend, Arizona, a few miles below Glen Canyon Dam

The Colorado River (Spanish: Río Colorado) is one of the principal rivers (along with the Rio Grande) in the Southwestern United States and in northern Mexico. The 1,450-mile-long (2,330 km) river, the 5th longest in the United States, drains an expansive, arid watershed that encompasses parts of seven U.S. states and two Mexican states. The name Colorado derives from the Spanish language for "colored reddish" due to its heavy silt load. Starting in the central Rocky Mountains of Colorado, it flows generally southwest across the Colorado Plateau and through the Grand Canyon before reaching Lake Mead on the ArizonaNevada border, where it turns south toward the international border. After entering Mexico, the Colorado approaches the mostly dry Colorado River Delta at the tip of the Gulf of California between Baja California and Sonora.

Known for its dramatic canyons, whitewater rapids, and eleven U.S. National Parks, the Colorado River and its tributaries are a vital source of water for 40 million people. An extensive system of dams, reservoirs, and aqueducts divert almost its entire flow for agricultural irrigation and urban water supply. Its large flow and steep gradient are used to generate hydroelectricity, meeting peaking power demands in much of the Intermountain West. Intensive water consumption has dried up the lower 100 miles (160 km) of the river, which has rarely reached the sea since the 1960s. (Full article...)

Ross with the Montreal Wanderers, circa 1907–18

Arthur Howey Ross (January 13, 1885 – August 5, 1964) was a Canadian professional ice hockey player and executive from 1905 until 1954. Regarded as one of the best defenders of his era by his peers, he was one of the first to skate with the puck up the ice rather than pass it to a forward. He was on Stanley Cup championship teams twice in a playing career that lasted thirteen seasons; in January 1907 with the Kenora Thistles and 1908 with the Montreal Wanderers. Like other players of the time, Ross played for several different teams and leagues, and is most notable for his time with the Wanderers while they were members of the National Hockey Association (NHA) and its successor, the National Hockey League (NHL). In 1911 he led one of the first organized player strikes over increased pay. When the Wanderers' home arena burned down in January 1918, the team ceased operations and Ross retired as a player.

After several years as an on-ice official, he was named head coach of the Hamilton Tigers for one season. When the Boston Bruins were formed in 1924, Ross was hired as the first coach and general manager of the team. He would go on to coach the team on three separate occasions until 1945 and stayed as general manager until his retirement in 1954. Ross helped the Bruins finish first place in the league ten times and to win the Stanley Cup three times; Ross personally coached the team to two of those victories. After being hired by the Bruins, Ross, along with his wife and two sons, moved to a suburb of Boston, and he became an American citizen in 1938. He died near Boston in 1964. (Full article...)

Rogers Pass, a central feature in the park

Glacier National Park is part of a system of 43 parks and park reserves across Canada, and one of seven national parks in British Columbia. Established in 1886, the park encompasses 1,349 km2 (521 sq mi), and includes a portion of the Selkirk Mountains which are part of the larger grouping of mountains, the Columbia Mountains. It also contains the Rogers Pass National Historic Site.

The park's history is closely tied to two primary Canadian transportation routes, the Canadian Pacific Railway (CPR), completed in 1885, and the Trans-Canada Highway, completed in 1963. Rogers Pass in the centre of the park eluded explorers until 1881. The railway brought with it tourism, the establishment of Glacier National Park and the construction of a popular alpine hotel. The heavy winter snows and steep, avalanche-prone valleys of the park have been a major obstacle to transportation, necessitating much railway engineering and avalanche control measures.
