115-884: The North American Cordillera , sometimes also called the Western Cordillera of North America , the Western Cordillera , or the Pacific Cordillera , is the North American portion of the American Cordillera , the mountain chain system along the Pacific coast of the Americas . The North American Cordillera covers an extensive area of mountain ranges , intermontane basins , and plateaus in Western and Northwestern Canada , Western United States , and Mexico , including much of

230-550: A writing system , built huge pyramids and temples , had a complex calendar , and developed the concept of zero around 400 CE. The first recorded European references to North America are in Norse sagas where it is referred to as Vinland . The earliest verifiable instance of pre-Columbian trans-oceanic contact by any European culture with the North America mainland has been dated to around 1000 CE. The site , situated at

345-528: 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

460-648: A period of mountain building called the Laramide orogeny , between 80 and 55 mya. The formation of the Isthmus of Panama that connected the continent to South America arguably occurred approximately 12 to 15 mya, and the Great Lakes (as well as many other northern freshwater lakes and rivers) were carved by receding glaciers about 10,000 years ago. North America is the source of much of what humanity knows about geologic time periods. The geographic area that would later become

575-571: A powerful earthquake killed seven people in 2009. Volcanic eruptions are common in the region. In 1968, the Arenal Volcano , in Costa Rica, erupted and killed 87 people. Fertile soils from weathered volcanic lavas have made it possible to sustain dense populations in agriculturally productive highland areas. Central America has many mountain ranges ; the longest are the Sierra Madre de Chiapas ,

690-540: A variety of reactions, including curiosity, trading, cooperation, resignation, and resistance. The indigenous population declined substantially following European arrival, primarily due to the introduction of Eurasian diseases, such as smallpox , to which the indigenous peoples lacked immunity, and because of violent conflicts with Europeans. Indigenous culture changed significantly and their affiliation with political and cultural groups also changed. Several linguistic groups died out , and others changed quite quickly. On

805-823: Is 40 to 60 miles (60 to 100 km) wide, with the Sierra Nevada to the east and the Coast Ranges to the west. In northwestern Oregon, the fertile Willamette Valley lies between the Oregon Coast Range and the Cascades ; this depression continues north into Washington as the Puget Trough . The Gulf of California is a body of water that separates the Peninsular Ranges from the Sierra Madre Occidental on

1035-646: Is a mountain range on the Olympic Peninsula of western Washington in the United States . The mountains , part of the Pacific Coast Ranges , are not especially high – Mount Olympus is the highest at 7,962 ft (2,427 m) – but the western slopes of the Olympics rise directly out of the Pacific Ocean and are the wettest place in the 48 contiguous states. Most of the mountains are protected within

1150-640: Is a very large continent that extends from north of the Arctic Circle to south of the Tropic of Cancer . Greenland, along with the Canadian Shield , is tundra with average temperatures ranging from 10 to 20 °C (50 to 68 °F), but central Greenland is composed of a very large ice sheet. This tundra radiates throughout Canada, but its border ends near the Rocky Mountains (but still contains Alaska) and at

1265-511: Is an ancient craton which forms the geologic core of North America; it formed between 1.5 and 1.0 billion years ago during the Proterozoic eon. The Canadian Shield is the largest exposure of this craton. From the Late Paleozoic to Early Mesozoic eras, North America was joined with the other modern-day continents as part of the supercontinent Pangaea , with Eurasia to its east. One of

1380-761: Is an extremely arid region characterized by basin and range topography. The Colorado Plateau is an area of high desert located in Arizona , New Mexico , Colorado , and Utah , bisected by the Colorado River which flows westward through the southern part, and the Green River which flows south from the northernmost part of the plateau. The Green is a tributary of the Colorado, the confluence being west of Moab, Utah in Canyonlands National Park. The Mexican Plateau

1495-535: Is in present-day Panama at the Darien Gap on the Colombia -Panama border, placing almost all of Panama within North America. Alternatively, some geologists physiographically locate its southern limit at the Isthmus of Tehuantepec , Mexico, with Central America extending southeastward to South America from this point. The Caribbean islands, or West Indies, are considered part of North America. The continental coastline

1610-560: Is located in southern British Columbia and northern Washington . The Interior Plateau also includes the Quesnel Highland , Fraser Plateau , Nechako Plateau , and McGregor Plateau . California's Central Valley is a large, flat valley that dominates the central portion of California , stretching inland and parallel to the Pacific Ocean coast. Its northern half is referred to as the Sacramento Valley , and its southern half as

1725-630: Is long and irregular. The Gulf of Mexico is the largest body of water indenting the continent, followed by Hudson Bay . Others include the Gulf of Saint Lawrence and the Gulf of California . Before the Central American isthmus formed, the region had been underwater. The islands of the West Indies delineate a submerged former land bridge , which had connected North and South America via what are now Florida and Venezuela . There are several islands off

1840-582: Is one of six distinct physiographic sections of the Basin and Range Province , which in turn is part of the Intermontane Plateaus physiographic division. It is a large arid-to-semiarid plateau that occupies much of northern and central Mexico . Averaging 1,825 m (5,988 ft) above sea level, it extends from the United States border in the north to the Trans-Mexican Volcanic Belt in

1955-548: Is part of North America geographically. In a geologic sense, Bermuda is not part of the Americas, but an oceanic island that was formed on the fissure of the Mid-Atlantic Ridge over 100 million years ago (mya). The nearest landmass to it is Cape Hatteras , North Carolina . However, Bermuda is often thought of as part of North America, especially given its historical, political and cultural ties to Virginia and other parts of

2070-686: Is the Morrison Formation of the western U.S. Canada is geologically one of the oldest regions in the world, with more than half of the region consisting of Precambrian rocks that have been above sea level since the beginning of the Palaeozoic era. Canada's mineral resources are diverse and extensive. Across the Canadian Shield and in the north there are large iron, nickel, zinc , copper, gold, lead, molybdenum , and uranium reserves. Large diamond concentrations have been recently developed in

2185-461: Is the humid subtropical climate . This area has the wettest cities in the contiguous U.S. , with annual precipitation reaching 67 in (1,700 mm) in Mobile, Alabama . Stretching from the borders of the humid continental and subtropical climates, and going west to the Sierra Nevada , south to the southern tip of Durango , north to the border with tundra climate, the steppe / desert climates are

2300-451: 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. Europe's colonization in North America led to most North Americans speaking European languages, such as English , Spanish , and French , and

2415-509: 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

2530-551: The Bering Strait during the Early-Middle Holocene . Prior to the arrival of European explorers and colonists in North America, the natives of North America were divided into many different polities, ranging from small bands of a few families to large empires. They lived in several culture areas , which roughly correspond to geographic and biological zones that defined the representative cultures and lifestyles of

2645-576: The British Columbia Coast , Western Canada , and Northern Canada . In the U.S., they include New England , the Mid-Atlantic , South Atlantic states , East North Central states , West North Central states , East South Central states , West South Central states , Mountain states , and Pacific states . The Great Lakes region and the Pacific Northwest include areas in both Canada and

2760-863: The Caribbean Plate , whereas the Juan de Fuca Plate and Cocos Plate border the North American Plate on its western frontier. The continent can be divided into four great regions (each of which contains many subregions): the Great Plains stretching from the Gulf of Mexico to the Canadian Arctic ; the geologically young, mountainous west, including the Rocky Mountains , the Great Basin , California , and Alaska ;

2875-597: The Cascade Range and the Rocky Mountains , cut through by the Columbia River . In one of various usages, the term " Columbia Basin " refers to more or less the same area as the Columbia Plateau. The Basin and Range province covers most of the state of Nevada and parts of the states of Arizona , California , Idaho , New Mexico , Oregon , Texas , Utah , and Wyoming , as well as much of northern Mexico . It

2990-610: The Coast Range Arc whereas the metamorphic formed when intruding magma heated the surrounding rock to produce schist . The Insular Mountains extend from Vancouver Island in the south to Haida Gwaii in the north on the British Columbia Coast . It contains two main mountain ranges, the Vancouver Island Ranges on Vancouver Island and the Queen Charlotte Mountains on Haida Gwaii. The Olympic Mountains

3105-553: The Cordillera Isabelia , and the Cordillera de Talamanca . Between the mountain ranges lie fertile valleys that are suitable for the people; in fact, most of the population of Honduras, Costa Rica, and Guatemala live in valleys. Valleys are also suitable for the production of coffee, beans, and other crops. The indigenous peoples of the Americas have many creation myths , based on which they assert that they have been present on

3220-459: The East Coast to eastern North Dakota , and stretching down to Kansas , is the humid continental climate featuring intense seasons, with a large amount of annual precipitation, with places like New York City averaging 50 in (1,300 mm). Starting at the southern border of the humid continental climate and stretching to the Gulf of Mexico (whilst encompassing the eastern half of Texas)

3335-648: The Eocene (55–50 million years ago) and Oligocene (34–23 million years ago), but since that time the region has been relatively stable. Generally speaking, it will be convenient here to consider these three belts going west to east, and north to south. In Alaska , south of the Interior Plains area, is the Rocky Mountain System, then the Intermontane Basins and Ranges, and in the southern part of

3450-686: The Hazelton Mountains and Coast Range to the west and northwest. Within the Interior plateau, the Shuswap Highland consists of a portion of the foothills between the Thompson Plateau and Bonaparte Plateau on the west, and the Monashee Mountains and Cariboo Mountains on the east and northeast. Also within the Interior plateau, the Thompson Plateau forms the southern portion of

3565-734: The Holarctic realm of the northern Western Hemisphere . While the plateau stretches from north to south, the southern east-west arc of the Central Mexican Plateau from Jalisco to Veracruz states historically as well as today has served as the population nexus of the Mexican nation, it is home to its biggest metro areas of Guadalajara , León , Querétaro , Morelia , Mexico City , Toluca , Cuernavaca , and Puebla .

The Cascade Range (called the Cascade Mountains in Canada) extends from northern California in the United States to British Columbia , Canada. It consists of non-volcanic and volcanic mountains: all of the known historic eruptions in

3910-466: The Inuit of the high Arctic arrived in North America much later than other native groups, evidenced by the disappearance of Dorset culture artifacts from the archaeological record and their replacement by the Thule people . During the thousands of years of native habitation on the continent, cultures changed and shifted. One of the oldest yet discovered is the Clovis culture (c. 9550–9050 BCE) in modern New Mexico . Later groups include

4025-440: The Liard River , just south of the British Columbia – Yukon border near Watson Lake, Yukon . The trench bottom is 3 to 16 km (2 to 10 miles) wide and ranges from 600 to 900 m (2,000 to 3,000 ft) above sea level. The general orientation of the Trench is almost uniformly pointing north. Some of its topography has been carved into glacial valleys , but it is primarily a byproduct of faulting . The Trench separates

4140-431: The Mexican mainland. The Gulf of California is 1,126 km (700 miles) long and 48 to 241 km (30 to 150 miles) wide, with an area of 177,000 km (68,000 sq mi), a mean depth of 818.08 m (2,684.0 ft), and a volume of 145,000 km (35,000 cu mi). The Rocky Mountain Trench is a large valley that extends approximately 1,600 km (990 mi) from Flathead Lake , Montana , to

4255-478: The Mississippian culture and related Mound building cultures, found in the Mississippi River valley and the Pueblo culture of what is now the Four Corners . The more southern cultural groups of North America were responsible for the domestication of many common crops now used around the world, such as tomatoes, squash , and maize . As a result of the development of agriculture in the south, many other cultural advances were made there. The Mayans developed

4370-440: The Okanagan Range , which lies along the Cascades' northeastern margin, separated by the Similkameen River . The Sierra Nevada forms an inland mountain spine of northern California, extending from the terminus of the Cascade Range south of Lassen Peak southwards along the east flank of the Central Valley of California to the Transverse Ranges , forming a mountain region of complex terrain and varied geology which separates

4485-431: The Rio Grande (Río Bravo del Norte) through the states of Chihuahua , Coahuila , Durango , Zacatecas and San Luis Potosí . Various narrow, isolated ridges cross the Mesa del Norte and numerous depressions also dot the region, the largest of which is the Bolsón de Mapimí . The Río Bravo del Norte and its tributary, the Río Conchos , drain portions of the northern plateau, and the Río Pánuco and its tributaries drain

4600-423: The Rocky Mountains on its east from the Columbia Mountains and the Cassiar Mountains on its west. It is up to 25 km (16 miles) wide, if measured peak-to-peak. For convenience the Rocky Mountain Trench may be divided into northern and southern sections. The dividing point reflects the separation of north and easterly flows to the Arctic Ocean versus south and westerly flows to the Pacific Ocean. A break in

The North Cascades are very different in character from the series of high volcanic stratovolcanoes from Rainier southwards to Mount Shasta and Lassen Peak , and are more severely alpine and steeply rugged, particularly the Skagit Range . Inland portions of the range are dryland and plateau-like in character, e.g.

5060-435: The U.S. state of Alaska to the southern border of Mexico , and includes some of the highest peaks on the continent. Its mountain ranges generally run north to south along three main belts: the Pacific Coast Ranges in the west, the Nevadan belt in the middle (including the Sierra Nevada ), and the Laramide belt in the east (including the Rocky Mountains ). These three orogenic belts (also called "orogens") arose due to

5175-403: 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

5290-403: The Yukon Territory at Champagne Pass and Chilkat Pass northwest of Haines, Alaska . The Saint Elias Mountains lie to their west and northwest, while the Yukon Ranges and Yukon Basin lie to their north. On the inland side of the Boundary Ranges are the Tahltan and Tagish Highlands and also the Skeena Mountains , part of the Interior Mountains system, which also extend southwards on

5405-412: The Yukon , Canada. This range has an area of 364,710 km (140,820 sq mi). The Coast Mountains run from the lower Fraser River and the Fraser Canyon northwestward, separating the Interior Plateau from the Pacific Ocean. Their coastal flank is characterized by an intense network of fjords and associated islands, very similar to the Norwegian coastline , while their inland side against

5520-420: The first official name given to Mexico. North America includes several regions and subregions, each of which have their own respective cultural, economic, and geographic regions. Economic regions include several regions formalized in 20th- and 21st-century trade agreements, including NAFTA between Canada , Mexico , and the United States , and CAFTA between Central America , the Dominican Republic , and

5635-401: The 1490s, building cities, putting the resident indigenous populations to work, raising crops for Spanish settlers and panning gold to enrich the Spaniards. Much of the indigenous population died due to disease and overwork, spurring the Spaniards on to claim new lands and peoples. An expedition under the command of Spanish settler, Hernán Cortés , sailed westward in 1519 to what turned out to be

5750-462: The Arctic, making Canada one of the world's largest producers. Throughout the Shield, there are many mining towns extracting these minerals. The largest, and best known, is Sudbury , Ontario. Sudbury is an exception to the normal process of forming minerals in the Shield since there is significant evidence that the Sudbury Basin is an ancient meteorite impact crater . The nearby, but less-known Temagami Magnetic Anomaly has striking similarities to

5865-399: The California coast (the Transverse Ranges, Peninsular Ranges and the Klamath Mountains are not included). The Sierra Madre del Sur mountains in southwestern Mexico form a southern extension of the Peninsular Ranges of Baja California . The Peninsular Ranges are separated from the Sierra Madre del Sur by an expanse of ocean. The Nevadan belt is located between the Pacific coast belt and

5980-478: The Caribbean islands. France took the western half of Hispaniola and developed Saint-Domingue as a cane sugar producing colony worked by black slave labor. Britain took Barbados and Jamaica , and the Dutch and Danes took islands previously claimed by Spain. Britain did not begin settling on the North American mainland until a hundred years after the first Spanish settlements, since it sought first to control nearby Ireland . The first permanent English settlement

6095-414: The Central Valley from the Great Basin to the east. The mean height of the mountain summits in the Sierra Nevada gradually increases from north to south, culminating at Mount Whitney (14,505 feet (4,421 m)), the highest point in the contiguous United States . From east to west, the Sierra is wedge-shaped: the west slope gradually rises and the east slope forms a steep escarpment , particularly so in

6210-418: The Cod fish", in reference to the abundance of cod fish on the East Coast . Waldseemüller used the Latin version of Vespucci's name, Americus Vespucius, in its feminine form of "America", following the examples of "Europa", "Asia", and "Africa". Americus originated from Medieval Latin Emericus (see Saint Emeric of Hungary ), coming from the Old High German name Emmerich . Map makers later extended

6325-407: The Interior Plateau. It is bordered on the south by the Canadian Cascades and on the north by the Thompson River . The Okanagan Highland is the part of the Interior Plateau to the east of the Thompson Plateau, and is bounded by the Okanagan River on the west, the Shuswap River on the north, and the Kettle River on the east side. The Okanagan Highland is described as being a hilly plateau, and

They include the Hazelton Mountains , Cassiar Mountains , Omineca Mountains , and Skeena Mountains . The Columbia Mountains are a designation in British Columbia for a group of four ranges lying between the Rocky Mountain Trench (to

6555-419: The North America's southeastern coast, Spanish explorer Juan Ponce de León , who had accompanied Columbus's second voyage, visited and named in 1513 La Florida . As the colonial period unfolded, Spain, England, and France appropriated and claimed extensive territories in North America eastern and southern coastlines. Spain established permanent settlements on the Caribbean islands of Hispaniola and Cuba in

6670-403: The North American Cordillera. Therefore, the intermontane areas can be divided up into the areas east of the Nevadan belt, and those west of the Nevadan belt. The Interior Plateau is the northern continuation of the Columbia Plateau , and covers much of inland British Columbia . The Cariboo Mountains and Monashee Mountains lie to the east, the Canadian Cascades are to the southwest, and

6785-477: The Rocky Mountains in the United States. To the west of the Monashees and Cariboos, there are three intermediary upland areas which are transitional between the mountain ranges and the plateaus flanking the Fraser and Thompson Rivers . These – the Quesnel , Shuswap and Okanagan Highlands , are sometimes considered as being part of the neighbouring ranges rather than the plateaus and are often spoken of that way locally but are formally designated as being part of

6900-449: The Selkirks and Monashees. The southward extension of the Selkirks, Purcells and Monashees into the United States are reckoned to be part of the Rocky Mountains and the designation Columbia Mountains is not used there (the Purcells, also, go by the name "Percell Mountains" in the United States). The Salish and Cabinet Mountains south of the Kootenai River are essentially part of the same landform, but are officially designated part of

7015-413: The Sierra Nevada, the Basin and Range Province (forming many narrow ranges and valleys), the Colorado Plateau , and the Rocky Mountains. In the United States, another major feature of the Cordillera is the Columbia Plateau , located north of California between the Cascade Range – which is a northern extension of the Sierra Nevada – and the Rocky Mountains.

North America is the third-largest continent by area after Asia and Africa . North America's only land connection to South America

7475-429: The United States has been the source of more varieties of dinosaurs than any other modern country. According to paleontologist Peter Dodson, this is primarily due to stratigraphy, climate and geography, human resources, and history. Much of the Mesozoic Era is represented by exposed outcrops in the many arid regions of the continent. The most significant Late Jurassic dinosaur-bearing fossil deposit in North America

7590-476: The United States that are considered part of the Rocky Mountains, and therefore the Columbia Mountains are often treated as being part of the Rockies. The Selkirks and Purcells lie entirely within the basin of the Columbia River, while the Monashees lie to the river's west on its southward course from its Big Bend and are flanked on the west by the basin of the Thompson and Okanagan Rivers . There are many named subranges of all four subgroupings, particularly in

7705-550: The United States, and Mexico. France , Italy , Portugal , Spain , Romania , Greece , and the countries of Latin America use a six-continent model , with the Americas viewed as a single continent and North America designating a subcontinent comprising Canada , the United States , Mexico, and Saint Pierre and Miquelon (politically part of France), and often including Greenland and Bermuda . North America has historically been known by other names, including Spanish North America, New Spain , and América Septentrional,

7820-527: The United States. North America is divided linguistically and culturally into two primary regions, Anglo-America and Latin America . Anglo-America includes most of North America, Belize , and Caribbean islands with English -speaking populations. There are also regions, including Louisiana and Quebec , with large Francophone populations; in Quebec , French is the official language. . The southern portion of North America includes Central America and non-English speaking Caribbean nations. The north of

The Oregon Coast Range is the part of the Coast Range system that is denoted as between the mouth of the Columbia River and the Middle Fork Coquille River . It is about 200 miles (320 km) long. The highest peak is Marys Peak , at 4,101 ft (1,250 m). The California Coast Ranges are one of the eleven traditional geomorphic provinces of California. This province includes several – but not all – mountain ranges along

8165-466: The contiguous United States have been from the volcanoes of the Cascade Volcanic Arc . The highest peak in the Cascade Range is Mount Rainier (14,409 feet (4,392 m)), a stratovolcano . The small portion of the Cascade Range in Canada is called the Cascade Mountains or Canadian Cascades, and in its southwestern area is similar in terrain to the area north of Glacier Peak , known as the North Cascades , and its northern and eastern extremities verge on

8280-432: The continent maintains recognized regions as well. In contrast to the common definition of North America, which encompasses the whole North American continent, the term "North America" is sometimes used more narrowly to refer only to four nations, Canada, Greenland, Mexico, and the U.S. The U.S. Census Bureau includes Saint Pierre and Miquelon, but excludes Mexico from its definition. The term Northern America refers to

8395-919: The continent's coasts; principally, the Arctic Archipelago, the Bahamas , Turks and Caicos , the Greater and Lesser Antilles , the Aleutian Islands (some of which are in the Eastern Hemisphere proper), the Alexander Archipelago , the many thousand islands of the British Columbia Coast, and Newfoundland. Greenland , a self-governing Danish island, and the world's largest , is on the same tectonic plate (the North American Plate ) and

8510-578: The continent. The vast majority of North America is on the North American Plate. Parts of western Mexico, including Baja California, and of California , including the cities of San Diego , Los Angeles , and Santa Cruz , lie on the eastern edge of the Pacific Plate , with the two plates meeting along the San Andreas Fault . The southernmost portion of the continent and much of the West Indies lie on

8625-640: The cordillera can be divided up into the areas east of the Nevadan belt, and those west of the Nevadan belt. The Pacific Coast Ranges, comprising the Pacific Coast Belt, parallel the North American Pacific Coast, and comprise several mountain systems. Along the British Columbia and Alaska coast, the mountains intermix with the sea in a complex maze of fjords , with thousands of islands. Off

Central America is geologically active with volcanic eruptions and earthquakes occurring from time to time. In 1976 Guatemala was hit by a major earthquake , killing 23,000 people; Managua, the capital of Nicaragua, was devastated by earthquakes in 1931 and 1972, the last one killing about 5,000 people; three earthquakes devastated El Salvador, one in 1986 and two in 2001; one earthquake devastated northern and central Costa Rica in 2009, killing at least 34 people; in Honduras

8855-725: The cultures of the region commonly reflect Western traditions . However, relatively small parts of North America in Canada, the United States, Mexico, and Central America have indigenous populations that continue adhering to their respective pre-European colonial cultural and linguistic traditions. The Americas were named after the Italian explorer Amerigo Vespucci by German cartographers Martin Waldseemüller and Matthias Ringmann . Vespucci explored South America between 1497 and 1502, and

8970-447: The driest in the U.S. Highland climates cut from north to south of the continent, where subtropical or temperate climates occur just below the tropics, as in central Mexico and Guatemala . Tropical climates appear in the island regions and in the subcontinent's bottleneck, found in countries and states bathed by the Caribbean Sea or to the south of the Gulf of Mexico and the Pacific Ocean . Precipitation patterns vary across

9085-792: The east) and the Interior Plateau (to the west). These ranges are the Cariboo Mountains , which are the northernmost and sometimes considered to be part of the Interior Plateau, the Selkirk Mountains , the Purcell Mountains , and the Monashee Mountains . The Columbia Mountains are classified as being in Canada's interior system, rather than its eastern system. However, the Columbia Mountains are an extension of mountains in

Stretching from

9315-612: The engagement of tectonic plates which deformed the Earth's lithosphere (crust and uppermost mantle). For example, the Laramide orogeny changed the topography of the central Rocky Mountains and adjoining Laramide regions (from central Montana to central New Mexico) during the Late Cretaceous 80 million years ago. Prior to this time the Rocky Mountain region was occupied by a broad basin. Further topographical evolution occurred during

9430-544: The first American inhabitants sailed from Beringia some 13,000 years ago, with widespread habitation of the Americas during the end of the Last Glacial Period , in what is known as the Late Glacial Maximum , around 12,500 years ago. The oldest petroglyphs in North America date from 15,000 to 10,000 years before present. Genetic research and anthropology indicate additional waves of migration from Asia via

9545-900: The geographic center of either the 50 states, the conterminous United States, or the North American continent." Nonetheless, there is a 4.6-meter (15 ft) field stone obelisk in Rugby claiming to mark the center. The North American continental pole of inaccessibility is located 1,650 km (1,030 mi) from the nearest coastline, between Allen and Kyle, South Dakota at 43°22′N 101°58′W  /  43.36°N 101.97°W  / 43.36; -101.97  ( Pole of Inaccessibility North America ) .

9660-419: The indigenous people who lived there, including the bison hunters of the Great Plains and the farmers of Mesoamerica . Native groups also are classified by their language families , which included Athapascan and Uto-Aztecan languages. Indigenous peoples with similar languages did not always share the same material culture , however, and were not necessarily always allies. Anthropologists speculate that

9775-745: The inland side of the Kitimat Ranges . The terrain of the main spine of the Coast Mountains is typified by heavy glaciation, including several very large icefields of varying elevation. Of the three subdivisions, the Pacific Ranges are the highest and are crowned by Mount Waddington , while the Boundary Ranges contain the largest icefields, the Juneau Icefield being the largest. The Kitimat Ranges are lower and less glacier-covered than either of

9890-650: The interior system includes the Columbia Mountains , and the eastern system includes the Canadian Rockies . At its midsection between San Francisco , California and Denver , Colorado , the North American Cordillera is about 1,000 miles (1,600 km) wide, and its physiographic provinces at this midpoint are as follows, going from west to east: the Pacific Coast Ranges, the Central Valley ,

10005-460: The land since its creation, but there is no evidence that humans evolved there. The specifics of the initial settlement of the Americas by ancient Asians are subject to ongoing research and discussion. The traditional theory has been that hunters entered the Bering Land Bridge between eastern Siberia and present-day Alaska from 27,000 to 14,000 years ago. A growing viewpoint is that

10120-411: The length of British Columbia. The Sierra Madre Oriental mountains in eastern Mexico are a southern extension of the Rocky Mountains . The Sierra Madre Oriental spans about 1,000 km (600 miles). Mexico's Gulf Coastal Plain lies to the east of the range, between the mountains and the Gulf of Mexico coast. The Mexican Plateau lies to the west of the range. The Nevadan belt runs down the middle of

10235-692: The mainland in Mexico. With local indigenous allies, the Spanish conquered the Aztec empire in central Mexico in 1521. Spain then established permanent cities in Mexico, Central America, and Spanish South America in the sixteenth century. Once Spaniards conquered the high civilization of the Aztecs and Incas, the Caribbean was a backwater of the Spanish empire. Other European powers began to intrude on areas claimed by Spain, including

10350-862: The middle into the main range of the Rockies and the coast ranges in California , Oregon , Washington , and British Columbia , with the Great Basin—a lower area containing smaller ranges and low-lying deserts—in between. The highest peak is Denali in Alaska. The U.S. Geographical Survey (USGS) states that the geographic center of North America is "6 miles [10 km] west of Balta, Pierce County, North Dakota " at about 48°10′N 100°10′W  /  48.167°N 100.167°W  / 48.167; -100.167 , about 24 kilometers (15 mi) from Rugby, North Dakota . The USGS further states that "No marked or monumented point has been established by any government agency as

Major subranges include the British Mountains and Richardson Mountains , towards their eastern end, and at their farthest west is the small subrange that De Long Mountains . The Brooks Range forms

11040-448: The other two groupings, but are extremely rugged and dense. The Coast Mountains are made of igneous and metamorphic rock from an episode of arc volcanism related to subduction of the Kula and Farallon Plates during the Laramide orogeny about 100 million years ago. The widespread granite forming the Coast Mountains formed when magma intruded and cooled at depth beneath volcanoes of

11155-647: The plateau they transition to the high plateau in dryland valleys notable for a series of large lakes similar to the alpine lakes of southern Switzerland, beginning in deep mountains and ending in flatland. They are subdivided in three main groupings, the Pacific Ranges between the Fraser and Bella Coola , the Kitimat Ranges from there northwards to the Nass River and the Boundary Ranges from there to their terminus in

11270-586: The raised but relatively flat plateau of the Canadian Shield in the northeast; and the varied eastern region, which includes the Appalachian Mountains, the coastal plain along the Atlantic seaboard, and the Florida peninsula. Mexico, with its long plateaus and cordilleras , falls largely in the western region, although the eastern coastal plain does extend south along the Gulf. The western mountains are split in

11500-478: The results of the formation of Pangaea was the Appalachian Mountains , which formed some 480 mya, making it among the oldest mountain ranges in the world. When Pangaea began to rift around 200 mya, North America became part of Laurasia , before it separated from Eurasia as its own continent during the mid- Cretaceous period. The Rockies and other western mountain ranges began forming around this time from

11615-532: The south and is bounded by the Sierra Madre Occidental and Sierra Madre Oriental to the west and east, respectively. A low east–west mountain range in the state of Zacatecas divides the plateau into northern and southern sections. These two sections, called the Northern Plateau (Spanish: Mesa del Norte ) and Central Plateau (Spanish: Mesa Central ), are now generally regarded by geographers as sections of one plateau. North America North America

The Chihuahuan Desert extends across the northern portion of the northern plateau, while the Meseta Central matorral covers the central portion, and the Central Mexican matorral extends from the southern portion of the northern plateau across

11845-436: The southern plateau. The Mesa Central or southern plateau is higher than its northern counterpart, averaging 2,000 m (6,600 ft) in elevation. The southern plateau contains numerous valleys originally formed by ancient lakes. It extends across the states of Aguascalientes , Jalisco , Zacatecas , Guanajuato , Querétaro , and Michoacán . Several of Mexico's most prominent cities, including Guadalajara, are located in

In the Alaska panhandle , the mainland mountain ranges and offshore islands (the Alexander Archipelago ) are extensions of respective ranges further south. In Canada, the North American Cordillera is usually divided into three physiographic regions: the western system, the interior system, and the eastern system. The western system includes the Coast Mountains ,

The precise boundaries of this cordillera and its subregions, as well as the names of its various features, may differ depending on the definitions in each country or jurisdiction, and also depending on the scientific field; this cordillera is a particularly prominent subject in the scientific field of physical geography . The North American Cordillera extends from

12420-481: The valley system at around 54°N near Prince George , British Columbia may be used for this purpose. There are three main mountain ranges in the Canadian area named the Rocky Mountains, the Columbia Mountains, and the Coast Mountains. The Columbia Plateau is a geologic and geographic region that lies across parts of the U.S. states of Washington , Oregon , and Idaho . It is a wide flood basalt plateau between

12535-575: The valleys of the southern plateau. Much of the southern plateau is drained by the Río Grande de Santiago and its tributaries, including the Río Lerma , which drain west into the Pacific Ocean . Tributaries of the Río Pánuco drain the eastern portion of the southern plateau. The Central Mexican matorral covers much of the southern plateau, with the subtropical Bajío dry forests occupying the lower portions of

12650-562: The western mainland of Mexico. The high plateau that is formed by the range is cut by deep river valleys. The Laramide belt is on the side of the North American Cordillera most distant from the Pacific Coast Ranges. It is named for the Laramie Mountains of eastern Wyoming (in turn named for Jacques La Ramee , a trapper who disappeared in the Laramie Mountains in 1820 and was never heard from again). The Brooks Range includes

12765-540: Was called the Council of the Indies . The United Nations and its statistics division recognize North America as including three regions: Northern America, Central America , and the Caribbean . "Northern America" is a distinct term from "North America", excluding Central America, which itself may or may not include Mexico . In the limited context of regional trade agreements, the term is used to reference three nations: Canada,

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

12995-790: Was in Jamestown, Virginia in 1607, followed by additional colonial establishments on the east coast from present-day Georgia in the south to Massachusetts in the north, forming the Thirteen Colonies of British America. The English did not establish settlements north or east of the St. Lawrence Valley in present-day Canada until after the conclusion of the American Revolutionary War . Britain's early settlements in present-day Canada included St. John's, Newfoundland in 1630 and Halifax, Nova Scotia in 1749. The first permanent French settlement

13110-521: Was in Quebec City, Quebec in 1608 Mexican Plateau A low east-west mountain range in the state of Zacatecas divides the plateau into northern and southern sections. These two sections, called the Northern Plateau ( Mesa del Norte ) and Central Plateau ( Mesa Central ), are now generally regarded by geographers as sections of one plateau. The Mexican Plateau is mostly covered by deserts and xeric shrublands , with pine-oak forests covering

13225-468: Was the first European to suggest that the Americas represented a landmass not then known to the Europeans. In 1507, Waldseemüller published a world map, and placed the word "America" on the continent of present-day South America. The continent north of present-day Mexico was then referred to as Parias. On a 1553 world map published by Petrus Apianus , North America was called "Baccalearum", meaning "realm of
