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. As of 2021, 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" can refer to Canada, the United States, Mexico, and Greenland or, alternatively, Canada, Greenland and the US (Mexico being classified as part of Latin America) or simply Canada and the US (Greenland being classified as either Arctic or European (due to its political status as a part of Denmark) and Mexico classified as Latin American).

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...)

Stelmach in 2006

Edward Michael Stelmach ECA AOE (/ˈstɛlmæk/; born May 11, 1951) is a Canadian politician who served as the 13th premier of Alberta, from 2006 to 2011. The grandson of Ukrainian immigrants, Stelmach was born and raised on a farm near Lamont and fluently speaks the distinctive Canadian dialect of Ukrainian. He spent his entire pre-political adult life as a farmer, except for some time spent studying at the University of Alberta. His first foray into politics was a 1986 municipal election, when he was elected to Lamont County council. A year into his term, he was appointed reeve. He continued in this position until his entry into provincial politics.

In the 1993 provincial election, Stelmach was elected as the Member of the Legislative Assembly (MLA) for Vegreville-Viking (later Fort Saskatchewan-Vegreville). A Progressive Conservative, he served in the cabinets of Ralph Klein—at various times holding the portfolios of Intergovernmental Relations, Transportation, Infrastructure, and Agriculture, Food, and Rural Development—where he developed a reputation as a low-key politician who avoided the limelight. When Klein resigned the party's leadership in 2006, Stelmach was among the first to present his candidature to replace him. After a third-place finish on the first ballot of the leadership race, he won an upset second ballot victory over former provincial treasurer Jim Dinning. (Full article...)

Mount Elbert seen from Turquoise Lake

Mount Elbert is the highest summit of the Rocky Mountains of North America. With an elevation of 14,438 feet (4400.58 m), it is also the highest point in the U.S. state of Colorado and the second-highest summit in the contiguous United States after Mount Whitney, which is slightly taller. The ultra-prominent fourteener is the highest peak in the Sawatch Range, as well as the highest point in the entire Mississippi River drainage basin. Mount Elbert is located in San Isabel National Forest, 12.1 miles (19.4 km) southwest (bearing 223°) of the city of Leadville in Lake County, Colorado.

The mountain was named in honor of a Colorado statesman, Samuel Hitt Elbert, who was active in the formative period of the state and Governor of the Territory of Colorado from 1873 to 1874. Henry W. Stuckle of the Hayden Survey was the first to record an ascent of the peak, in 1874. The easiest and most popular climbing routes are categorized as Class 1 to 2 or A+ in mountaineering parlance. Mount Elbert is therefore often referred to as the "gentle giant" that tops all others in the Rocky Mountains. (Full article...)
