100-680: The valley forms a relatively isolated enclave west of the Cascade Range along the north side of the Siskiyou Mountains . It is separated from the nearby coast by a high section of the Southern Oregon Coast Range . The valley is characterized by a mild climate that allows a long growing season, especially for many varieties of fruits, nuts and herbs. A regional manufacturing industry is centered in Medford,

200-633: A humid continental climate with widely variable precipitation. For example, the average daily low in Prince George (roughly in the middle of the province) in January is −12 °C (10 °F). Small towns in the southern interior with high elevation such as Princeton are typically colder and snowier than cities in the valleys. Heavy snowfall occurs in all elevated mountainous terrain providing bases for skiers in both south and central British Columbia. Annual snowfall on highway mountain passes in

300-632: A major eruption of Mount St. Helens in 1980 . Minor eruptions of Mount St. Helens have also occurred since, most recently from 2004 to 2008. The Cascade Range is a part of the American Cordillera , a nearly continuous chain of mountain ranges (cordillera) that form the western "backbone" of North, Central , and South America . The Cascades are home to many national parks and protected areas, including North Cascades National Park , Mount Rainier National Park , Crater Lake National Park , and Lassen Volcanic National Park . The northern half of

400-489: A chain of volcanoes (the Cascade Volcanic Arc) above the subduction zone. Soil conditions for farming are generally good, especially downwind of volcanoes . This is largely because volcanic rocks are often rich in potassium -bearing minerals such as orthoclase , and erode relatively easily. Volcanic debris, especially lahars , also helps to spread mineral-rich volcanic material, and the storage of water in

500-798: A few wolf packs returning from Canada live in the Cascades. Fewer than 50 grizzly bears reside in the Cascades of Canada and Washington. British Columbia British Columbia (commonly abbreviated as BC ) is the westernmost province of Canada . Situated in the Pacific Northwest between the Pacific Ocean and the Rocky Mountains , the province has a diverse geography, with rugged landscapes that include rocky coastlines, sandy beaches, forests, lakes, mountains, inland deserts and grassy plains. British Columbia borders

600-602: A few strikingly large volcanoes, like Mount Hood and Mount St. Helens, that dominate the landscape. The Cascade volcanoes define the Pacific Northwest section of the Ring of Fire , an array of volcanoes that rim the Pacific Ocean. The Ring of Fire is also known for its frequent earthquakes. The volcanoes and earthquakes arise from a common source: subduction , where the dense Juan de Fuca Plate plunges beneath

700-620: A fur trader with the North West Company , seeking a viable route across the mountains, explored and crossed the northern Cascades between Fort Okanogan and Puget Sound. His report of the journey is vague about the route taken. He followed the lower Methow River into the mountains. He might have used Cascade Pass to reach the Skagit River . Ross was the first European-American to explore the Methow River area and likely

800-528: A series of devastating epidemics of diseases the people had no immunity to. The population dramatically collapsed, culminating in the 1862 smallpox outbreak in Victoria that spread throughout the coast. European settlement did not bode well for the remaining native population of British Columbia. Colonial officials deemed colonists could make better use of the land than the First Nations people, and thus

900-838: A small island off the coast of Haida Gwaii . Many healthy populations of fish are present, including salmonids such as several species of salmon , trout , steelhead , and char . Besides salmon and trout, sport-fishers in BC also catch halibut , bass , and sturgeon . On the coast, harbour seals and river otters are common. Cetacean species native to the coast include the orca , humpback whale , grey whale , harbour porpoise , Dall's porpoise , Pacific white-sided dolphin and minke whale . Some endangered species in British Columbia are: Vancouver Island marmot , spotted owl , American white pelican , and badgers. White spruce or Engelmann spruce and their hybrids occur in 12 of

1000-712: A traveler passes through the Cascade Range, the climate first gets colder, then warmer and drier east of the crest. Most of the Cascades' lower and middle elevations are covered in coniferous forest ; the higher altitudes have extensive meadows as well as alpine tundra and glaciers . The southern part of the Cascades are within the California Floristic Province , an area of high biodiversity . Silver fir predominates above 2500 ft, while there are moors , meadows , and mountain hemlock / subalpine fir groves from 4500 to 6000 ft on

1100-660: A very wide range of birds, has long been popular. Bears ( grizzly , black —including the Kermode bear or spirit bear) live here, as do deer , elk , moose , caribou , big-horn sheep , mountain goats , marmots , beavers , muskrats , coyotes , wolves , mustelids (such as wolverines , badgers and fishers ), cougars , eagles , ospreys , herons , Canada geese , swans , loons , hawks , owls , ravens , harlequin ducks , and many other sorts of ducks. Smaller birds ( robins , jays , grosbeaks , chickadees , and so on) also abound. Murrelets are known from Frederick Island,

1200-455: A wholly unorganized area of British North America under the de facto jurisdiction of HBC administrators; however, unlike Rupert's Land to the north and east, the territory was not a concession to the company. Rather, it was simply granted a monopoly to trade with the First Nations inhabitants. All that was changed with the westward extension of American exploration and the concomitant overlapping claims of territorial sovereignty, especially in

1300-538: Is Vancouver . Vancouver and its suburbs together make up the third-largest metropolitan area in Canada , with the 2021 census recording 2.6   million people in Metro Vancouver . British Columbia is Canada's third-largest province in terms of total area, after Quebec and Ontario . The first known human inhabitants of the area settled in British Columbia at least 10,000 years ago. Such groups include

1400-546: Is a diverse and cosmopolitan province, drawing on a plethora of cultural influences from its British Canadian , European , and Asian diasporas , as well as the Indigenous population . Though the province's ethnic majority originates from the British Isles , many British Columbians also trace their ancestors to continental Europe , East Asia , and South Asia . Indigenous Canadians constitute about 6 percent of

1500-602: Is a major mountain range of western North America , extending from southern British Columbia through Washington and Oregon to Northern California . It includes both non-volcanic mountains, such as many of those in the North Cascades , and the notable volcanoes known as the High Cascades . The small part of the range in British Columbia is referred to as the Canadian Cascades or, locally, as

1600-596: Is a significant centre for maritime trade : the Port of Vancouver is the largest port in Canada and the most diversified port in North America . Although less than 5 percent of the province's territory is arable land , significant agriculture exists in the Fraser Valley and Okanagan due to the warmer climate. British Columbia is home to 45% of all publicly listed companies in Canada. The province's name

1700-546: Is an arid plateau that was largely formed 17 to 14 million years ago by the many flows of the Columbia River Basalt Group . Together, these sequences of fluid volcanic rock form the 200,000-square-mile (520,000 km ) Columbia Plateau in eastern Washington, Oregon, and parts of western Idaho. The Columbia River Gorge is the only major break of the range in the United States. When

1800-762: Is an interpretive site there now at "The End of The Oregon Trail". The road was constructed as a toll road – $ 5 per wagon – and was very successful. In addition, the Applegate Trail was created to allow settlers to avoid rafting down the Columbia River. The Trail used the path of the California Trail to north-central Nevada . From there, the Trail headed northwest into northern California, and continued northwest towards today's Ashland, Oregon . From there, settlers would head north along

1900-561: Is generally in the subarctic climate zone, but even there, milder air can penetrate far inland. The coldest temperature in British Columbia was recorded in Smith River , where it dropped to −58.9 °C (−74.0 °F) on January 31, 1947, one of the coldest readings recorded anywhere in North America. Atlin in the province's far northwest, along with the adjoining Southern Lakes region of Yukon , get midwinter thaws caused by

2000-710: Is great local relief . The southern part of the Canadian Cascades, particularly the Skagit Range , is geologically and topographically similar to the North Cascades, while the northern and northeastern parts are less glaciated and more plateau-like, resembling nearby areas of the Thompson Plateau . The range is near the Pacific Ocean and in the region's prevailing westerly winds , so it receives significant rain and snowfall, especially on

2100-485: Is home to First Nations groups that have a deep history with a significant number of indigenous languages. There are more than 200 First Nations in BC. Prior to contact (with non-Aboriginal people), human history is known from oral histories, archaeological investigations, and from early records from explorers encountering societies early in the period. The arrival of Paleoindians from Beringia took place between 20,000 and 12,000 years ago. Hunter-gatherer families were

2200-406: Is home to at least 34 distinct Indigenous languages . Major sectors of British Columbia's economy include forestry , mining , filmmaking and video production , tourism , real estate , construction , wholesale , and retail . Its main exports include lumber and timber , pulp and paper products, copper , coal , and natural gas . British Columbia exhibits high property values and

2300-529: Is known as the North Cascades in the United States but is formally named the Cascade Mountains north of the Canada–United States border , reaching to the northern extremity of the Cascades at Lytton Mountain . Overall, the North Cascades and Canadian Cascades are extremely rugged; even the lesser peaks are steep and glaciated, and valleys are quite low relative to peaks and ridges, so there

2400-465: Is not uncommon for some places in the Cascades to have over 500 inches (1,300 cm) of annual snow accumulation, such as at Lake Helen , near Lassen Peak. Most of the High Cascades are therefore white with snow and ice year-round. The western slopes are densely covered with Douglas-fir ( Pseudotsuga menziesii ), western hemlock ( Tsuga heterophylla ) and red alder ( Alnus rubra ), while

2500-480: Is now the United States include Vancouver, Washington ( Fort Vancouver ), formerly the "capital" of Hudson's Bay operations in the Columbia District, Colville, Washington and Walla Walla, Washington (old Fort Nez Percés ). With the amalgamation of the two fur trading companies in 1821, modern-day British Columbia existed in three fur trading departments. The bulk of the central and northern interior

2600-406: Is the only province in Canada that borders the Pacific Ocean. British Columbia's highest mountain is Mount Fairweather ; the highest mountain entirely within the province is Mount Waddington . British Columbia's capital is Victoria , located at the southeastern tip of Vancouver Island . Only a narrow strip of Vancouver Island, from Campbell River to Victoria, is significantly populated. Much of

2700-490: The Baker River is dammed to form Lake Shannon and Baker Lake . The Cascades harbor a largely-untapped potential for geothermal power . The U.S. Geological Survey Geothermal Research Program has been investigating this potential. Some of this energy is already being used in places like Klamath Falls, Oregon , where volcanic steam is used to heat public buildings. The highest recorded underground temperature found in

2800-631: The Cascade Mountains . The highest peak in the range is Mount Rainier in Washington at 14,411 feet (4,392 m). The Cascades are part of the Pacific Ocean 's Ring of Fire , the ring of volcanoes and associated mountains around the Pacific Ocean. All of the eruptions in the contiguous United States over the last 200 years have been from the Cascade Volcanoes . The two most recent were Lassen Peak from 1914 to 1921 and

2900-626: The Cascades Rapids in the Columbia River Gorge, a feature on the river now submerged beneath the Bonneville Reservoir . Before long, the great white-capped mountains that loomed above the rapids were called the "mountains by the cascades" and later simply as the "Cascades". The earliest attested use of the name "Cascade Range" is in the writings of botanist David Douglas in 1825. In 1814, Alexander Ross ,

3000-1059: The Chinook effect, which is also common (and much warmer) in more southerly parts of the Interior. During winter on the coast, rainfall , sometimes relentless heavy rain, dominates because of consistent barrages of cyclonic low-pressure systems from the North Pacific. Average snowfall on the coast during a normal winter is between 25 and 50 centimetres (10 and 20 in), but on occasion (and not every winter) heavy snowfalls with more than 20 centimetres (8 in) and well below freezing temperatures arrive when modified arctic air reaches coastal areas, typically for short periods, and can take temperatures below −10 °C (14 °F), even at sea level. Arctic outflow winds can occasionally result in wind chill temperatures at or even below −17.8 °C (0.0 °F). While winters are very wet, coastal areas are generally milder and dry during summer under

3100-599: The Coast Salish , Tsilhqotʼin , and Haida peoples, among many others. One of the earliest British settlements in the area was Fort Victoria , established in 1843, which gave rise to the city of Victoria, the capital of the Colony of Vancouver Island . The Colony of British Columbia (1858–1866) was subsequently founded by Richard Clement Moody , and by the Royal Engineers, Columbia Detachment , in response to

3200-628: The Columbia in the name Columbia Rediviva came from the name Columbia for the New World or parts thereof , a reference to Christopher Columbus . The governments of Canada and British Columbia recognize Colombie-Britannique as the French name for the province. British Columbia is bordered to the west by the Pacific Ocean and the American state of Alaska , to the north by Yukon and

3300-646: The Dakelh (Carrier) and the Tsilhqotʼin . The inlets and valleys of the British Columbia coast shelter large, distinctive populations, such as the Haida , Kwakwakaʼwakw and Nuu-chah-nulth , sustained by the region's abundant salmon and shellfish. These peoples developed complex cultures dependent on the western red cedar that included wooden houses, seagoing whaling and war canoes and elaborately carved potlatch items and totem poles . Contact with Europeans brought

3400-597: The Fraser Canyon , close to the confluence of the Fraser and Thompson rivers, where the terrain is rugged and covered with desert-type flora. Semi-desert grassland is found in large areas of the Interior Plateau , with land uses ranging from ranching at lower altitudes to forestry at higher ones. The northern, mostly mountainous, two-thirds of the province is largely unpopulated and undeveloped, except for

3500-577: The Fraser Canyon Gold Rush . Moody selected the site for and founded the mainland colony's capital New Westminster . The colonies of Vancouver Island and British Columbia were incorporated in 1866, subsequent to which Victoria became the united colony's capital. In 1871, British Columbia entered Confederation as the sixth province of Canada, in enactment of the British Columbia Terms of Union . British Columbia

3600-665: The Hudson's Bay Company (HBC) at Fort Vancouver near today's Portland, Oregon . From this base HBC trapping parties traveled throughout the Cascades in search of beaver and other fur-bearing animals. For example, using what became known as the Siskiyou Trail , Hudson's Bay Company trappers were the first non-natives to explore the southern Cascades in the 1820s and 1830s, establishing trails which passed near Crater Lake , Mount McLoughlin , Medicine Lake Volcano , Mount Shasta , and Lassen Peak. The course of political history in

3700-467: The Inside Passage 's many inlets provide some of British Columbia's renowned and spectacular scenery, which forms the backdrop and context for a growing outdoor adventure and ecotourism industry. 75 percent of the province is mountainous (more than 1,000 m [3,300 ft] above sea level ); 60 percent is forested; and only about 5 percent is arable. The province's mainland away from

3800-527: The Lushootseed name for Mount Rainier, and "Louwala-Clough", meaning "smoking mountain" for Mount St. Helens. In early 1792, British navigator George Vancouver explored Puget Sound and gave English names to the high mountains he saw. Mount Baker was named for Vancouver's third lieutenant, Joseph Baker , although the first European to see it was Manuel Quimper , who named it la gran montaña del Carmelo ("Great Mount Carmel ") in 1790. Mount Rainier

3900-528: The North American Plate . As the oceanic slab sinks deep into the Earth's interior beneath the continental plate, high temperatures and pressures allow water molecules locked in the minerals of solid rock to escape. The water vapor rises into the pliable mantle above the subducting plate, causing some of the mantle to melt. This newly formed magma rises toward the Earth's surface to erupt, forming

4000-531: The North Coast just south of Southeast Alaska . The exception to British Columbia's wet and cloudy winters is during the El Niño phase. During El Niño events, the jet stream is much farther south across North America, making the province's winters milder and drier than normal. Winters are much wetter and cooler during the opposite phase, La Niña . There are 14 designations of parks and protected areas in

4100-562: The North West Company and the Hudson's Bay Company (HBC), effectively established a permanent British presence in the region. The Columbia District was broadly defined as being south of 54°40 north latitude, (the southern limit of Russian America ), north of Mexican-controlled California, and west of the Rocky Mountains . It was, by the Anglo-American Convention of 1818 , under the "joint occupancy and use" of citizens of

4200-658: The Northwest Territories , to the east by the province of Alberta , and to the south by the American states of Washington , Idaho , and Montana . The southern border of British Columbia was established by the 1846 Oregon Treaty, although its history is tied with lands as far south as California . British Columbia's land area is 944,735 square kilometres (364,800 sq mi). British Columbia's rugged coastline stretches for more than 27,000 kilometres (17,000 mi), and includes deep, mountainous fjords and about 6,000 islands, most of which are uninhabited. It

4300-581: The Oroville–Osoyoos Border Crossing , is one of several wine and cider -producing regions in Canada. Other wine regions in British Columbia include the Cowichan Valley on Vancouver Island and the Fraser Valley . The Southern Interior cities of Kamloops and Penticton have some of the warmest and longest summer climates in Canada (while higher elevations are cold and snowy), although their temperatures are often exceeded north of

4400-805: The Pacific Crest Trail follows the range. The Cascades extend northward from Lassen Peak (also known as Mount Lassen) in northern California to the confluence of the Nicola and Thompson rivers in British Columbia . The Fraser River separates the Cascades from the Coast Mountains in Canada, as does the Willamette Valley from the upper portion of the Oregon Coast Range . The highest volcanoes of

4500-568: The Pacific Northwest saw the spine of the Cascade Range being proposed as a boundary settlement during the Oregon Dispute of 1846. The United States rejected the proposal and insisted on the 49th parallel north , which cuts across the range just north of Mount Baker. Throughout the period of dispute and up to the creation of the Crown Colony of British Columbia in 1858, the Hudson's Bay Company's York Factory Express route, as well

4600-628: The fur trade , rather than political considerations. In 1794, by the third of a series of agreements known as the Nootka Conventions , Spain conceded its claims of exclusivity in the Pacific. This opened the way for formal claims and colonization by other powers, including Britain, but because of the Napoleonic Wars , there was little British action on its claims in the region until later. The establishment of trading posts by

4700-469: The railway roadbed and the Othello Tunnels , now decommissioned, are popular tourist recreation destinations for hiking and bicycling. The pass is used by the Coquihalla Highway , a government megaproject built as part of the Expo 86 spending boom of the 1980s, which is now the main route from the Coast to the British Columbia interior. Traffic formerly went via the Fraser Canyon , to the west, or via Allison Pass and Manning Park along Highway 3 to

4800-1101: The 14 biogeoclimatic zones of British Columbia . Common types of trees present in BC's forests include western redcedar , yellow-cedar , Rocky Mountain juniper , lodgepole pine , ponderosa or yellow pine , whitebark pine , limber pine , western white pine , western larch , tamarack , alpine larch , white spruce , Engelmann spruce , Sitka spruce , black spruce , grand fir , Amabilis fir , subalpine fir , western hemlock , mountain hemlock , Douglas-fir , western yew , Pacific dogwood , bigleaf maple , Douglas maple , vine maple , arbutus , black hawthorn , cascara , Garry oak , Pacific crab apple , choke cherry , pin cherry , bitter cherry , red alder , mountain alder , paper birch , water birch , black cottonwood , balsam poplar , trembling aspen . First Nations peoples of British Columbia used plants for food, and to produce material goods like fuel and building products. Plant foods included berries, and roots like camas . Environment Canada subdivides British Columbia into six ecozones : The area now known as British Columbia

4900-526: The 14 different designations that includes over 800 distinct areas. British Columbia contains seven of Canada's national parks and National Park Reserves: British Columbia contains a large number of provincial parks , run by BC Parks under the aegis of the Ministry of Environment. British Columbia's provincial parks system is the second largest parks system in Canada, the largest being Canada's National Parks system. Another tier of parks in British Columbia are regional parks , which are maintained and run by

5000-552: The Cascades began to rise 7 million years ago in the late Miocene , the Columbia River drained the relatively low Columbia Plateau. As the range grew, erosion from the Columbia River was able to keep pace, carving out the gorge and major pass seen today. The gorge also exposes uplifted and warped layers of basalt from the plateau. Before European exploration, First Nations tribes named many peaks, including "Wy'east" for Mount Hood , "Seekseekqua" for Mount Jefferson (Oregon) , "M'laiksini Yaina" for Mount McLoughlin , "Tahoma",

5100-414: The Cascades, known as the High Cascades, dominate their surroundings, often standing twice the height of the nearby mountains. They often have a visual height (height above nearby crestlines) of one mile or more. The highest peaks, such as the 14,411-foot (4,392 m) Mount Rainier, dominate their surroundings for 50 to 100 miles (80 to 161 km). The northern part of the range, north of Mount Rainier,

5200-551: The Interior during mid-summer, with the record high of 49.6 °C (121.3 °F) being held in Lytton on June 29, 2021, during a record-breaking heat wave that year . The extended summer dryness often creates conditions that spark forest fires, from dry-lightning or man-made causes. Many areas of the province are often covered by a blanket of heavy cloud and low fog during the winter months, in contrast to abundant summer sunshine. Annual sunshine hours vary from 2200 near Cranbrook and Victoria to less than 1300 in Prince Rupert , on

5300-476: The Pacific Ocean, inscribing a stone marking his accomplishment on the shoreline of Dean Channel near Bella Coola . His expedition theoretically established British sovereignty inland, and a succession of other fur company explorers charted the maze of rivers and mountain ranges between the Canadian Prairies and the Pacific. Mackenzie and other explorers—notably John Finlay , Simon Fraser , Samuel Black , and David Thompson —were primarily concerned with extending

5400-664: The United States and subjects of Britain (which is to say, the fur companies). This co-occupancy was ended with the Oregon Treaty of 1846. The major supply route was the York Factory Express between Hudson Bay and Fort Vancouver . Some of the early outposts grew into settlements, communities, and cities. Among the places in British Columbia that began as fur trading posts are Fort St. John (established 1794); Hudson's Hope (1805); Fort Nelson (1805); Fort St. James (1806); Prince George (1807); Kamloops (1812); Fort Langley (1827); Fort Victoria (1843); Yale (1848); and Nanaimo (1853). Fur company posts that became cities in what

5500-484: The area east of the Rockies , where the Peace River Country contains BC's portion of the Canadian Prairies , centred at the city of Dawson Creek . British Columbia is considered part of the Pacific Northwest and the Cascadia bioregion , along with the American states of Alaska, Idaho, (western) Montana, Oregon , Washington, and (northern) California . Because of the many mountain ranges and rugged coastline, British Columbia's climate varies dramatically across

5600-429: The blocking presence of successive mountain ranges, the climate of some of the interior valleys of the province (such as the Thompson, parts of the Fraser Canyon, the southern Cariboo and parts of the Okanagan) is semi-arid with certain locations receiving less than 250 millimetres (10 in) in annual precipitation. The annual mean temperature in the most populated areas of the province is up to 12 °C (54 °F),

5700-429: The coast in 1775. In doing so, Pérez and Quadra reasserted the Spanish claim for the Pacific coast , first made by Vasco Núñez de Balboa in 1513. The explorations of James Cook in 1778 and George Vancouver in 1792 and 1793 established British jurisdiction over the coastal area north and west of the Columbia River. In 1793, Sir Alexander Mackenzie was the first European to journey across North America overland to

5800-426: The coastal regions is somewhat moderated by the Pacific Ocean. Terrain ranges from dry inland forests and semi-arid valleys, to the range and canyon districts of the Central and Southern Interior , to boreal forest and subarctic prairie in the Northern Interior. High mountain regions both north and south have subalpine flora and subalpine climate . The Okanagan wine area , extending from Vernon to Osoyoos at

5900-414: The drier eastern slopes feature mostly ponderosa pine ( Pinus ponderosa ), with some western larch ( Larix occidentalis ), mountain hemlock ( Tsuga mertensiana ) and subalpine fir ( Abies lasiocarpa ) and subalpine larch ( Larix lyallii ) at higher elevations. Annual rainfall is as low as 9 inches (230 mm) on the eastern foothills due to a rain shadow effect. Beyond the eastern foothills

6000-439: The early 1840s, at first only marginally. Following the Oregon Treaty the inward flux of migration from the Oregon Trail intensified and the passes and back-valleys of what is now the state of Washington were explored and populated, and it was not long after that railways followed. Despite its being traversed by several major freeways and rail lines, and its lower flanks subjected to major logging in recent decades, large parts of

6100-477: The established Siskiyou Trail into the Willamette Valley . With the exception of the 1915 eruption of remote Lassen Peak in Northern California, the range was quiet for more than a century. Then, on May 18, 1980, the dramatic eruption of Mount St. Helens shattered the quiet and brought the world's attention to the range. Geologists were also concerned that the St. Helens eruption was a sign that long-dormant Cascade volcanoes might become active once more, as in

6200-403: The first to explore the Stehekin River and Bridge Creek region. Due to the difficulty of crossing the northern Cascades and the paucity of beaver, fur-trading companies made only a few explorations into the mountains north of the Columbia River after Ross. Exploration and settlement of the Cascades region by Europeans and Americans was accelerated by the establishment of a major trading post of

6300-421: The form of snow and ice is also important for agriculture. The snow-capped mountains, such as Mt. Hood and Mt. Bachelor , are used as ski resorts in the late winter, while in the summer they become popular hiking and mountaineering locations. Much of their meltwater eventually flows into reservoirs, where it is used for recreation, while its potential energy is captured to generate hydroelectric power before

6400-427: The influence of stable anti-cyclonic high pressure. Southern Interior valleys are hot in summer; for example, in Osoyoos , the July maximum temperature averages 31.7 °C (89.1 °F), making it the hottest month of any location in Canada; this hot weather sometimes spreads towards the coast or to the far north of the province. Temperatures often exceed 40 °C (104 °F) in the lower elevations of valleys in

6500-425: The islands of southern Alaska and northern British Columbia. The Na-Dene language group is believed to be linked to the Yeniseian languages of Siberia: the Dene of the western Arctic may represent a distinct wave of migration from Asia to North America. The Interior of British Columbia is home to the Salishan language groups such as the Shuswap (Secwepemc) , Okanagan and Athabaskan language groups, primarily

6600-423: The land should be owned by the colonists. To ensure colonists would be able to settle properly and make use of the land, First Nations were forcibly relocated onto reserves , which were often too small to support their way of life. By the 1930s, British Columbia had over 1500 reserves. Lands now known as British Columbia were added to the British Empire during the 19th century. Colonies originally begun with

6700-559: The main social structure from 10,000 to 5,000 years ago. The nomadic population lived in non-permanent structures foraging for nuts, berries and edible roots while hunting and trapping larger and small game for food and furs. Around 5,000 years ago individual groups started to focus on resources available to them locally. Coast Salish peoples had complex land management practices linked to ecosystem health and resilience. Forest gardens on Canada's northwest coast included crabapple, hazelnut, cranberry, wild plum, and wild cherry species. Thus with

6800-429: The mildest anywhere in Canada. The valleys of the Southern Interior have short winters with only brief bouts of cold or infrequent heavy snow, while those in the Cariboo , in the Central Interior , are colder because of increased altitude and latitude, but without the intensity or duration experienced at similar latitudes elsewhere in Canada. Outside of the driest valleys, the Southern and Central Interior generally have

6900-413: The most highly populated area of the valley. In recent years the valley has emerged as a wine -growing region and it is the location of the Rogue Valley AVA ( American Viticultural Area ). The mild climate and relative isolation have made the valley a popular retirement destination. The community of Ashland is famous for the Oregon Shakespeare Festival and Mount Ashland Ski Area . Interstate 5 follows

7000-442: The mountain range which contained these peaks. He referred to it simply as the "eastern snowy range". Earlier Spanish explorers called it Sierra Nevada , meaning "snowy mountains". In 1805, the Lewis and Clark Expedition passed through the Cascades on the Columbia River, which for many years was the only practical way to pass that part of the range. They were the first non-indigenous people to see Mount Adams , but they thought it

7100-410: The native population of what became British Columbia. The arrival of Europeans began around the mid-18th century, as fur traders entered the area to harvest sea otters . While it is thought Sir Francis Drake may have explored the British Columbian coast in 1579, it was Juan Pérez who completed the first documented voyage, which took place in 1774. Juan Francisco de la Bodega y Quadra explored

7200-718: The older Hudson's Bay Company Brigade Trail from the Canyon to the Interior, the Dewdney Trail, and older routes which connected east to the Similkameen and Okanagan valleys. The southern mainline of the Canadian Pacific Railway penetrated the range via the passes of the Coquihalla River , along one of the steepest and snowiest routes in the entire Pacific Cordillera . Near Hope, B.C. ,

7300-584: The passage of time there is a pattern of increasing regional generalization with a more sedentary lifestyle . These indigenous populations evolved over the next 5,000 years across a large area into many groups with shared traditions and customs. To the northwest of the province are the peoples of the Na-Dene languages , which include the Athapaskan-speaking peoples and the Tlingit , who live on

7400-597: The period from 1800 to 1857 when a total of eight erupted. None have erupted since St. Helens, but precautions are being taken nevertheless, such as the Cascades Volcano Observatory and Mount Rainier Volcano Lahar Warning System in Pierce County, Washington . The Cascade Range is made up of a band of thousands of very small, short-lived volcanoes that have built a platform of lava and volcanic debris. Rising above this volcanic platform are

7500-405: The province of Alberta to the east; the territories of Yukon and Northwest Territories to the north; the U.S. states of Washington , Idaho and Montana to the south, and Alaska to the northwest. With an estimated population of over 5.6   million as of 2024, it is Canada's third-most populous province . The capital of British Columbia is Victoria , while the province's largest city

7600-401: The province that reflect the different administration and creation of these areas in a modern context. There are 141 ecological reserves, 35 provincial marine parks, 7 provincial heritage sites, 6 National Historic Sites of Canada , 4 national parks and 3 national park reserves. 12.5 percent of the province's area (114,000 km or 44,000 sq mi) is considered protected under one of

7700-536: The province's regional districts . The Ministry of Forests operates forest recreation sites. In addition to these areas, over 47,000 square kilometres (18,000 sq mi) of arable land are protected by the Agricultural Land Reserve . Much of the province is undeveloped, so populations of many mammalian species that have become rare in much of the United States still flourish in British Columbia. Watching animals of various sorts, including

7800-613: The province's total population. Christianity is the largest religion in the region, though the majority of the population is non-religious. English is the common language of the province, although Punjabi , Mandarin Chinese , and Cantonese also have a large presence in the Metro Vancouver region. The Franco-Columbian community is an officially recognized linguistic minority, and around one percent of British Columbians claim French as their mother tongue . British Columbia

7900-561: The province. Coastal southern British Columbia has a mild and rainy climate influenced by the North Pacific Current . Most of the region is classified as oceanic , though pockets of warm-summer Mediterranean climate also exist in the far-southern parts of the coast. Precipitation averages above 1,000 mm (39 in) in almost all of the coastal region, and Hucuktlis Lake on Vancouver Island receives an average of 6,903 mm (271.8 in) of rain annually. Due to

8000-466: The range is 510 °F (266 °C) at 3,075 feet (937 m) below Newberry Volcano 's caldera floor. Forests of large, coniferous trees ( western red cedars , Douglas-firs, western hemlocks, firs , pines , spruces , and others) dominate most of the Cascade Range. Cool, wet winters and warm, dry summers (largely a result of oceanic influence) favor evergreen species, whereas mild temperatures and rich soils promote fast and prolonged growth. As

8100-420: The range remain intense and forbidding alpine wilderness. Much of the northern half of the Cascades, from Rainier north, have been preserved by U.S. national or British Columbia provincial parks (such as E.C. Manning Provincial Park ), or other forms of protected area. The Canadian side of the range has a history that includes the Fraser Canyon Gold Rush of 1858–60 and its famous Cariboo Road , as well as

8200-524: The route of fur brigades, followed the Okanogan River along the east edge of the Cascades and the Columbia River through the range. Passes across the range were not well known and little used. Naches Pass was used for driving cattle and horses to Fort Nisqually . Yakima Pass was also used by the Hudson's Bay Company. American settlement of the flanks of the Coast Range did not occur until

8300-691: The south, near the border. The Barlow Road was the first established land path for U.S. settlers through the Cascade Range in 1845, and formed the final overland link for the Oregon Trail (previously, settlers had to raft down the treacherous rapids of the Columbia River). The Road left the Columbia at what is now Hood River and passed along the south side of Mount Hood at what is now Government Camp , terminating in Oregon City. There

8400-598: The southern Columbia Basin (within present day Washington and Oregon ). In 1846, the Oregon Treaty divided the territory along the 49th parallel to the Strait of Georgia , with the area south of this boundary (excluding Vancouver Island and the Gulf Islands ) transferred to sole American sovereignty. The Colony of Vancouver Island was created in 1849, with Victoria designated as the capital. New Caledonia, as

8500-472: The southern interior rivals some of the snowiest cities in Canada, and freezing rain and fog are sometimes present on such roads as well. This can result in hazardous driving conditions, as people are usually travelling between warmer areas such as Vancouver or Kamloops , and may be unaware that the conditions may be slippery and cold. Winters are generally severe in the Northern Interior which

8600-653: The summer. Because of the combination of heat and dry air, wildfires are a problem during the summer, and frequently, smoke will fill up the valley for weeks, reducing visibility and air quality. On average, the first frost occurs October 22, and the last on May 6. The Rogue Valley is in USDA plant hardiness zones 7–9. Sub-zero temperatures are extremely rare in the valley; the Rogue Valley International-Medford Airport has not recorded such extreme cold weather since December 21, 1990, when

8700-561: The support of the Hudson's Bay Company (Vancouver Island, the mainland) were amalgamated, then entered Confederation as British Columbia in 1871 as part of the Dominion of Canada. During the 1770s, smallpox killed at least 30 percent of the Pacific Northwest First Nations . This devastating epidemic was the first in a series; the 1862 Pacific Northwest smallpox epidemic killed about half to two-thirds of

8800-495: The temperature dropped to −2 °F or −18.9 °C. Due to the valley's generally mild climate, it is used as a region to grow pears , and there are multiple vineyards . Medford has, on average, 175 sunny days per year, compared to 80 on average for the Willamette Valley , and 65 on average for the coast. 42°26′24″N 122°55′34″W  /  42.440124°N 122.926154°W  / 42.440124; -122.926154 Cascade Range The Cascade Range or Cascades

8900-653: The valley through Ashland, Medford and Grants Pass. In the early 19th century the first European Americans began to pass through the valley, inhabited by the Shasta , Takelma , and Rogue River Athabaskan tribes of Native Americans . The early fur traders named this river the "River of the Rogues". White settlers began to arrive in the valley after the Donation Land Act , which allocated 640 acres (2.6 km) of land to each married couple. Between 1836 and 1856,

9000-554: The valley was the scene of a series of bloody conflicts between European Americans and the Rogue River tribes. In 1850 gold was discovered on the Rogue River; the next year gold was discovered in the nearby mountains. Early mining activity was centered on the lower Rogue River, on Althouse Creek in Josephine County, and near the now-restored town of Jacksonville , west of Medford. During the gold rush some $ 70 million

9100-450: The water is used to irrigate crops. Because of the abundance of powerful streams, many of the major westward-draining rivers of the Cascades have been dammed to provide hydroelectric power . One of these, Ross Dam on the Skagit River , retains a reservoir which spans the border southeast of Hope, British Columbia , extending 2 miles (3.2 km) into Canada. At the foot of the southeast flank of Mount Baker, at Concrete, Washington ,

9200-471: The west side. The treeline is at ~6000 feet. On the east side, subalpine forests of larch trees grade to pine and interior fir forests below 4200 ft, which grade to ponderosa below 2500 ft, which in turn grades to semidesert scrub near sea level. Above 7500 ft, the landscape is barren with either no plants or only moss and lichen . Black bears , coyotes , bobcats , cougars , beavers , deer , elk , moose , mountain goats and

9300-561: The western part of Vancouver Island and the rest of the coast is covered by temperate rainforest . The province's most populous city is Vancouver, which is at the confluence of the Fraser River and Georgia Strait , in the mainland's southwest corner (an area often called the Lower Mainland ). By land area, Abbotsford is the largest city. Vanderhoof is near the geographic centre of the province. The Coast Mountains and

9400-420: The western slopes due to orographic lift , with annual snow accumulations of up to 1,000 inches (2,500 cm) (= 83 feet (25 m)) in some areas. Mount Baker in Washington recorded a national record single-season snowfall in the winter of 1998–99 with 1,140 inches (2,900 cm) (= 95 feet (29 m)). Before that year, Mount Rainier held the American record for snow accumulation at Paradise in 1978. It

9500-457: Was Mount St. Helens. When they later saw Mount St. Helens they thought it was Mount Rainier. On their return trip, Lewis and Clark spotted a high but distant snowy pinnacle that they named for the sponsor of the expedition, U.S. President Thomas Jefferson . Lewis and Clark called the Cascade Range the "Western Mountains". The Lewis and Clark expedition, and the many settlers and traders that followed, met their last obstacle to their journey at

9600-682: Was chosen by Queen Victoria , when the Colony of British Columbia (1858–1866) , i.e., "the Mainland", became a British colony in 1858. It refers to the Columbia District , the British name for the territory drained by the Columbia River , in southeastern British Columbia, which was the namesake of the pre- Oregon Treaty Columbia Department of the Hudson's Bay Company . Queen Victoria chose British Columbia to distinguish what

9700-667: Was extracted from the area. Unlike the rest of Western Oregon, because of the rain shadow effect resulting from the close range of the Cascades and Siskiyous, the Rogue Valley is relatively dry when compared to the coast and Portland . Most of the valley has a hot-summer Mediterranean climate . Winters are chilly and rainy , but relatively dry and slightly colder when compared to the rest of western Oregon, with frequent fog , and occasional snow . Summers are hot and sunny, but dry, with low humidity . Temperatures surpass 100 °F or 37.8 °C, on an average of 10–15 days during

9800-564: Was named after Admiral Peter Rainier . Later in 1792, Vancouver had his lieutenant William Robert Broughton explore the lower Columbia River . He named Mount Hood after Lord Samuel Hood , an admiral of the Royal Navy . Mount St. Helens was sighted by Vancouver in May 1792, from near the mouth of the Columbia River. It was named for Alleyne FitzHerbert, 1st Baron St Helens , a British diplomat. Vancouver's expedition did not, however, name

9900-816: Was organized into the New Caledonia district, administered from Fort St. James. The interior south of the Thompson River watershed and north of the Columbia was organized into the Columbia District, administered from Fort Vancouver on the lower Columbia River. The northeast corner of the province east of the Rockies, known as the Peace River Block, was attached to the much larger Athabasca District , headquartered in Fort Chipewyan , in present-day Alberta. Until 1849, these districts were

10000-536: Was the British sector of the Columbia District from the United States' ("American Columbia" or "Southern Columbia"), which became the Oregon Territory on August 8, 1848, as a result of the treaty. Ultimately, the Columbia in the name British Columbia is derived from the name of the Columbia Rediviva , an American ship which lent its name to the Columbia River and later the wider region;
