125-697: John McLoughlin , baptized Jean-Baptiste McLoughlin , (October 19, 1784 – September 3, 1857) was a French-Canadian, later American, Chief Factor and Superintendent of the Columbia District of the Hudson's Bay Company at Fort Vancouver from 1824 to 1845. He was later known as the "Father of Oregon" for his role in assisting the American cause in the Oregon Country . In the late 1840s, his general store in Oregon City

250-623: A boundary along the Columbia River, the Oregon Treaty of 1846 set the boundary at the 49th parallel. As part of the treaty, the British retained all areas north of the line while the United States acquired the south. The Columbia River became much of the border between the U.S. territories of Oregon and Washington . Oregon became a U.S. state in 1859, while Washington later entered into

375-564: A complex network of dry canyon-like channels, or coulees that are often braided and sharply gouged into the basalt rock underlying the region's deep topsoil. Numerous flat-topped buttes with rich soil stand high above the chaotic scablands. Constrictions at several places caused the floodwaters to pool into large temporary lakes, such as Lake Lewis , in which sediments were deposited. Water depths have been estimated at 1,000 feet (300 m) at Wallula Gap and 400 feet (120 m) over modern Portland, Oregon. Sediments were also deposited when

500-524: A great extent in the shoe, furniture, hardware, and other industries. The number of trade areas in which factors operate has increased. In the United Kingdom, most factors fall within the definition of a mercantile agent under the Factors Act 1889 ( 52 & 53 Vict. c. 45), and therefore have the powers of such. A factor has a possessory lien over the consigned goods that covers any claims against

625-606: A partner in the company. In 1816, McLoughlin was charged with complicity in the massacre at the Red River Colony after the Battle of Seven Oaks . He and all the other parties from the North West Company were exonerated. The Hudson's Bay Company was found culpable by the appointed Royal Commissioner at its trial on October 30, 1818, and in the later prosecutions by Lord Selkirk and the successful counter-suits. McLoughlin

750-451: A person or firm (factoring company), accepts as assignee book debts ( accounts receivable ) as security for short-term loans; this is known as factoring . In Scottish law , a judicial factor is a kind of trustee appointed by the Court of Session to administer an estate, for a ward (called a pupil) until a guardian (called a tutor) can be appointed ( factor loco tutoris ), for a person who

875-734: A physician who had been in the fur trade since 1804, was appointed superintendent of the Columbia District. The HBC reoriented its Columbia District operations toward the Pacific Ocean via the Columbia, which became the region's main trunk route. In the early 1840s Americans began to colonize the Oregon country in large numbers via the Oregon Trail , despite the HBC's efforts to discourage American settlement in

1000-520: A population as great as 10,000. The site drew traders from as far away as the Great Plains. The Cascades Rapids of the Columbia River Gorge, and Kettle Falls and Priest Rapids in eastern Washington, were also major fishing and trading sites. In prehistoric times the Columbia's salmon and steelhead runs numbered an estimated annual average of 10 to 16 million fish. In comparison,

1125-471: A shifting sandbar that makes the river's mouth one of the most hazardous stretches of water to navigate in the world. Because of the danger and the many shipwrecks near the mouth, it acquired a reputation as the "Graveyard of Ships". The Columbia drains an area of about 258,000 sq mi (670,000 km ). Its drainage basin covers nearly all of Idaho , large portions of British Columbia, Oregon, and Washington, and ultimately all of Montana west of

1250-548: Is incapax , or for a partnership that is unable to function. Columbia River The Columbia River ( Upper Chinook : Wimahl or Wimal ; Sahaptin : Nch’i-Wàna or Nchi wana ; Sinixt dialect swah'netk'qhu ) is the largest river in the Pacific Northwest region of North America . The river forms in the Rocky Mountains of British Columbia , Canada. It flows northwest and then south into

1375-661: Is not federally recognized , who live near the lower Columbia River, call it Wimahl or Wimal in the Upper Chinook (Kiksht) language , and it is Nch’i-Wàna or Nchi wana to the Sahaptin (Ichishkíin Sɨ́nwit) -speaking peoples of its middle course in present-day Washington. The river is known as swah'netk'qhu by the Sinixt people , who live in the area of the Arrow Lakes in

1500-602: Is now located beside his home overlooking downtown Oregon City. McLoughlin is featured on the 1925 Fort Vancouver Centennial half dollar designed by Laura Gardin Fraser . In 1953, the state of Oregon donated to the National Statuary Hall Collection a bronze statue of McLoughlin, which is currently displayed at the Capitol Visitor Center . The title "Father of Oregon" was officially bestowed on him by

1625-467: The 49th parallel , ordered McLoughlin to relocate their regional headquarters to Vancouver Island . McLoughlin, in turn, directed James Douglas to construct Fort Camosun (now Victoria , British Columbia , Canada) in 1843. But McLoughlin, whose life was increasingly connected to the Willamette River Valley, refused to move there. McLoughlin was involved with the debate over the future of

1750-547: The Columbia River Plateau and forced the lower Columbia into its present course. The modern Cascade Range began to uplift 5 to 4 million years ago. Cutting through the uplifting mountains, the Columbia River significantly deepened the Columbia River Gorge. The river and its drainage basin experienced some of the world's greatest known catastrophic floods toward the end of the last ice age . The periodic rupturing of ice dams at Glacial Lake Missoula resulted in

1875-576: The Continental Divide , and small portions of Wyoming , Utah , and Nevada ; the total area is similar to the size of France. Roughly 745 mi (1,199 km) of the river's length and 85 percent of its drainage basin are in the US. The Columbia is the twelfth-longest river and has the sixth-largest drainage basin in the United States. In Canada, where the Columbia flows for 498 mi (801 km) and drains 39,700 sq mi (103,000 km ),

2000-702: The Eocene through the Miocene eras, tremendous volcanic eruptions frequently modified much of the landscape traversed by the Columbia. The lower reaches of the ancestral river passed through a valley near where Mount Hood later arose. Carrying sediments from erosion and erupting volcanoes, it built a 2-mile (3.2 km) thick delta that underlies the foothills on the east side of the Coast Range near Vernonia in northwestern Oregon. Between 17 million and 6 million years ago, huge outpourings of flood basalt lava covered

2125-683: The Grand Coulee . After the floods, the river found its present course, and the Grand Coulee was left dry. The construction of the Grand Coulee Dam in the mid-20th century impounded the river, forming Lake Roosevelt , from which water was pumped into the dry coulee , forming the reservoir of Banks Lake . The river flows past The Gorge Amphitheatre , a prominent concert venue in the Northwest, then through Priest Rapids Dam , and then through

2250-586: The Hanford Nuclear Reservation . Entirely within the reservation is Hanford Reach , the only U.S. stretch of the river that is completely free-flowing, unimpeded by dams, and not a tidal estuary . The Snake River and Yakima River join the Columbia in the Tri-Cities population center. The Columbia makes a sharp bend to the west at the Washington–Oregon border. The river defines that border for

2375-518: The Hudson's Bay Company , as restructured after merging with the North West Company in 1821, had commissioned officers who included the ranks of chief trader and chief factor. They all shared the profits of the company during its monopoly years. In the deed poll under which the HBC was governed, there were 25 chief factors and 28 chief traders. Chief factors usually held high administrative positions. The Dutch East India Company and

2500-705: The Kootenay River , and Trail , two major population centers of the West Kootenay region. The Pend Oreille River joins the Columbia about 2 miles (3 km) north of the United States–Canada border . The Columbia enters eastern Washington flowing south and turning to the west at the Spokane River confluence. It marks the southern and eastern borders of the Colville Indian Reservation and

2625-607: The Marmes Rockshelter , near the confluence of the Palouse and Snake rivers in eastern Washington. In 1996 the skeletal remains of a 9,000-year-old prehistoric man (dubbed Kennewick Man ) were found near Kennewick, Washington . The discovery rekindled debate in the scientific community over the origins of human habitation in North America and sparked a protracted controversy over whether the scientific or Native American community

2750-600: The Missouri River . The first documented European discovery of the Columbia River was that of Bruno de Heceta , who in 1775 sighted the river's mouth. On the advice of his officers, he did not explore it, as he was short-staffed and the current was strong. He considered it a bay, and called it Ensenada de Asunción ( Assumption Cove ). Later Spanish maps, based on his sighting, showed a river, labeled Río de San Roque ( The Saint Roch River ), or an entrance, called Entrada de Hezeta , named for Bruno de Hezeta , who sailed

2875-548: The Molala , Klickitat , Wenatchi , Okanagan, and Sinkiuse-Columbia peoples, who owned small numbers of horses and adopted few plains culture features. Some groups remained essentially unaffected, such as the Sanpoil and Nespelem people, whose culture remained centered on fishing. Natives of the region encountered foreigners at several times and places during the 18th and 19th centuries. European and American vessels explored

3000-630: The North West Company between Fort George , founded in 1811 by John Jacob Astor 's American Fur Company ) at the mouth of the Columbia River , to Fort William on Lake Superior . In the 1821 merger with the North West Company, the Hudson's Bay Company gained control of North West Company trading posts west of the Rocky Mountains. They established headquarters at Fort George (formerly Astoria). George Simpson , Governor of Hudson's Bay Company, visited

3125-461: The Oregon Country along the Clearwater and Snake rivers, and encountered numerous small settlements of natives. Their records recount tales of hospitable traders who were not above stealing small items from the visitors. They also noted brass teakettles, a British musket, and other artifacts that had been obtained in trade with coastal tribes. From the earliest contact with westerners, the natives of

3250-549: The Oregon Country . He advocated an independent nation that would be free of the United States during debates at the Oregon Lyceum in 1842 through his lawyer. This view won support at first and a resolution adopted but was later moved away from in favor of a resolution by George Abernethy of the Methodist Mission to wait on forming an independent country. In 1843, American settlers established their own government, called

3375-665: The Oregon Legislative Assembly in 1957, on the centennial of his death. Many landmarks in Oregon are named after him, including: McLoughlin's former residence in Oregon City, now known as the McLoughlin House , is today a museum; it is part of the Fort Vancouver National Historic Site . Factor (agent) Most modern factor business is in the textile field , but factors are also used to

3500-614: The Provisional Government of Oregon . A legislative committee drafted a code of laws known as the Organic Law . It included the creation of an executive committee of three, a judiciary, militia, land laws, and four counties. There was vagueness and confusion over the nature of the 1843 Organic Law, in particular, whether it was constitutional or statutory. In 1844, a new legislative committee decided to consider it statutory. The 1845 Organic Law made additional changes, including allowing

3625-628: The Red River colony . In November 1839, Sir George Simpson instructed Duncan Finlayson to begin promoting the PSAC among the Red River colonists. James Sinclair was appointed by Finlayson to guide the mostly Métis settler families to Fort Vancouver. In June 1841, the party left Fort Garry with 23 families consisting of 121 people. When they arrived at Fort Vancouver, they numbered 21 families of 116 people. Fourteen families were relocated to Fort Nisqually , while

3750-763: The Shoshone Bannock tribes are present. The Sinixt or Lakes people lived on the lower stretch of the Canadian portion, while above that the Shuswap people (Secwepemc in their own language) reckon the whole of the upper Columbia east to the Rockies as part of their territory. The Canadian portion of the Columbia Basin outlines the traditional homelands of the Canadian Kootenay– Ktunaxa . The Chinook tribe, which

3875-473: The Yakima War , decimated the native population and removed much land from native control. As years progressed, the right of natives to fish along the Columbia became the central issue of contention with the states, commercial fishers, and private property owners. The US Supreme Court upheld fishing rights in landmark cases in 1905 and 1918, as well as the 1974 case United States v. Washington , commonly called

4000-455: The eruption of Mount St. Helens deposited large amounts of sediment in the lower Columbia, temporarily reducing the depth of the shipping channel by 26 feet (7.9 m). Humans have inhabited the Columbia's watershed for more than 15,000 years, with a transition to a sedentary lifestyle based mainly on salmon starting about 3,500 years ago. In 1962, archaeologists found evidence of human activity dating back 11,230 years at

4125-469: The saline waters of the Pacific Ocean. These fish—especially the salmon species—provided the core subsistence for native peoples . The first documented European discovery of the Columbia River occurred when Bruno de Heceta sighted the river's mouth in 1775. On May 11, 1792, a private American ship, Columbia Rediviva, under Captain Robert Gray from Boston became the first non-indigenous vessel to enter

4250-540: The 16th-century Christopher and Cosmas . When the British government did not show interest, the castaways were sent to Macau so that they could be returned to Japan. Even that was not possible, as Japan did not allow any outside ships to enter its waters. In 1821, with the merger of HBC and the North West Company , the British Parliament imposed the laws of Upper Canada on British subjects in Rupert’s Land and

4375-534: The 1840s a mass migration of American settlers undermined British control. The Hudson's Bay Company tried to maintain dominance by shifting from the fur trade, which was in decline, to exporting other goods such as salmon and lumber. Colonization schemes were attempted, but failed to match the scale of American settlement. Americans generally settled south of the Columbia, mainly in the Willamette Valley. The Hudson's Bay Company tried to establish settlements north of

4500-452: The 1930s, there were natives who lived along the river and fished year round, moving along with the fish's migration patterns throughout the seasons. The Yakama were slower to do so, organizing a formal government in 1944. In the 21st century, the Yakama, Nez Perce, Umatilla, and Warm Springs tribes all have treaty fishing rights along the Columbia and its tributaries. In 1957 Celilo Falls

4625-473: The 20th century, each of these major fishing sites was flooded by a dam, beginning with Cascades Rapids in 1938. The development was accompanied by extensive negotiations between natives and US government agencies. The Confederated Tribes of Warm Springs, a coalition of various tribes, adopted a constitution and incorporated after the 1938 completion of the Bonneville Dam flooded Cascades Rapids; Still, in

This amounts to about 15 percent of the entire Columbia watershed. The Columbia's highest recorded flow, measured at The Dalles,

4875-594: The Boldt Decision. Fish were central to the culture of the region's natives, both as sustenance and as part of their religious beliefs. Natives drew fish from the Columbia at several major sites, which also served as trading posts. Celilo Falls , located east of the modern city of The Dalles, was a vital hub for trade and the interaction of different cultural groups, being used for fishing and trading for 11,000 years. Prior to contact with westerners, villages along this 9-mile (14 km) stretch may have at times had

5000-701: The British East India Company based factors at trading posts in numerous sites all over Asia. In 18th- and early 19th-century China and Japan, however, the governments limited European traders to small, defined areas: the Dutch Factory was allowed to operate on Dejima , an island off Nagasaki, before the opening of trade with Japan; and in China the British were limited to Thirteen Factories and Shamian Island areas of Canton . In territories without any other regular authorities, especially if in need of defence,

5125-489: The Columbia Bar, becoming the first known explorer of European descent to enter the river . Gray's fur trading mission had been financed by Boston merchants, who outfitted him with a private vessel named Columbia Rediviva ; he named the river after the ship on May 18. Gray spent nine days trading near the mouth of the Columbia, then left without having gone beyond 13 miles (21 km) upstream. The farthest point reached

5250-574: The Columbia Department remained highly profitable, in part due to the ongoing high demand for beaver hats in Europe. John McLoughlin was worried Fort Vancouver would be attacked and plundered of its heavy stock of supplies, due to its proximity to the Willamette Valley , in which there was already an American settlement of some size. By 1825, there were usually two brigades from opposite ends of

5375-536: The Columbia District in 1824–25, journeying from York Factory. He investigated a quicker route than previously used, following the Saskatchewan River and crossing the mountains at Athabasca Pass . This route was thereafter followed by the York Factory Express brigades. McLoughlin built Fort Vancouver as a replacement for Fort George, on the north side of the Columbia River , a few miles upstream from

5500-461: The Columbia District, and gave the authority to enforce those laws to the newly reconfigured Hudson's Bay Company . McLoughlin, as Superintendent of Fort Vancouver , applied the law to British subjects, kept peace with the natives and sought to maintain law and order over American settlers as well. In August 1828, McLoughlin was in charge at Fort Vancouver when American explorer Jedediah Smith , John Turner , Arthur Black, and Richard Leland arrived,

5625-486: The Columbia River Gorge, about 100 miles (160 km) upstream, sighting and naming Mount Hood. Broughton formally claimed the river, its drainage basin , and the nearby coast for Britain. In contrast, Gray had not made any formal claims on behalf of the United States. Because the Columbia was at the same latitude as the headwaters of the Missouri River, there was some speculation that Gray and Vancouver had discovered

5750-538: The Columbia River Gorge, sending massive amounts of debris south from Table Mountain and Greenleaf Peak into the gorge near the present site of Bonneville Dam. The most recent and significant is known as the Bonneville Slide , which formed a massive earthen dam, filling 3.5 miles (5.6 km) of the river's length. Various studies have placed the date of the Bonneville Slide anywhere between 1060 and 1760 AD;

5875-417: The Columbia River Gorge. The Celilo Canal , bypassing Celilo Falls, opened to river traffic in 1915. In the mid-20th century, the construction of dams along the length of the river submerged the rapids beneath a series of reservoirs. An extensive system of locks allowed ships and barges to pass easily between reservoirs. A navigation channel reaching Lewiston, Idaho , along the Columbia and Snake rivers,

6000-425: The Columbia River. The mountainous terrain where the unit would be placed in is Juniper Point, referred to by the Yakama as Pushpum. Pushpum has rock formations, as well as food and medicine capabilities that are essential to the Yakama. Members of the Yakama tribe wish for consent on the Goldendale project, as opposed to consultation. Some historians believe that Japanese or Chinese vessels blown off course reached

6125-406: The Columbia to improve navigation. Changes to the river over the years have included the construction of jetties at the river's mouth, dredging , and the construction of canals and navigation locks . Today, ocean freighters can travel upriver as far as Portland and Vancouver, and barges can reach as far inland as Lewiston, Idaho . The shifting Columbia Bar makes passage between the river and

In the 18th century, there was strong interest in discovering a Northwest Passage that would permit navigation between the Atlantic (or inland North America) and the Pacific Ocean. Many ships in the area, especially those under Spanish and British command, searched the northwest coast for a large river that might connect to Hudson Bay or

6375-402: The Lower Umpqua Tribe, Siuslaw Tribe, and Coos Tribe in 1984, the Klamath Tribe in 1986, and the Coquille Tribe in 1989. While all the aforementioned tribes received federally recognized status, the Chinook Indian Nation had their federal recognition revoked in 2002 by the Bush Administration, and are fighting to have it restored. In 2023, members of the Yakama Nation expressed their dismay for

6500-411: The Missoula Floods, with discharges exceeding the combined flow of all the other rivers in the world, dozens of times over thousands of years. The exact number of floods is unknown, but geologists have documented at least 40; evidence suggests that they occurred between about 19,000 and 13,000 years ago. The floodwaters rushed across eastern Washington, creating the channeled scablands , which are

6625-418: The Northwest Coast long before Europeans—possibly as early as 219  BCE . Historian Derek Hayes claims that "It is a near certainty that Japanese or Chinese people arrived on the northwest coast long before any European." It is unknown whether they landed near the Columbia. Evidence exists that Spanish castaways reached the shore in 1679 and traded with the Clatsop ; if these were the first Europeans to see

6750-421: The Pacific Ocean difficult and dangerous, and numerous rapids along the river hinder navigation. Pacific Graveyard, a 1964 book by James A. Gibbs , describes the many shipwrecks near the mouth of the Columbia. Jetties, first constructed in 1886, extend the river's channel into the ocean. Strong currents and the shifting sandbar remain a threat to ships entering the river and necessitate continuous maintenance of

6875-407: The Snake River, reaching the Columbia near the present-day Tri-Cities, Washington. They explored a few miles upriver, as far as Bateman Island , before heading down the Columbia, concluding their journey at the river's mouth and establishing Fort Clatsop , a short-lived establishment that was occupied for less than three months. Canadian explorer David Thompson , of the North West Company , spent

The river is 1,243 mi (2,000 km) long, and its largest tributary is the Snake River . Its drainage basin is roughly the size of France and extends into seven states of the United States and one Canadian province. The fourth-largest river in

7125-491: The Union in 1889. By the turn of the 20th century, the difficulty of navigating the Columbia was seen as an impediment to the economic development of the Inland Empire region east of the Cascades. The dredging and dam building that followed would permanently alter the river, disrupting its natural flow but also providing electricity, irrigation , navigability and other benefits to the region. American captain Robert Gray and British captain George Vancouver, who explored

7250-427: The United States by flow , the Columbia has the greatest flow of any river into the eastern Pacific. The Columbia and its tributaries have been central to the region's culture and economy for thousands of years. They have been used for transportation since ancient times, linking the region's many cultural groups. The river system hosts many species of anadromous fish, which migrate between freshwater habitats and

7375-462: The United States had become very strained, and many expected war to break out any time. McLoughlin's aid probably prevented an armed attack on his outpost by the numerous American settlers. The settlers understood that his motives were not purely altruistic, and some resented the assistance, working against him for the rest of his life. As tensions mounted in the Oregon boundary dispute ; Simpson, realizing that border might ultimately be as far north as

Fishermen placed on trial received sentences ranging from six months to five years. The federal government pinned Yakama Tribe member David Sohappy ringleader of the operation. After the trial ended, it was determined that the fish were not poached, but driven away because of harmful chemicals present in

7625-439: The adjoining Columbia Wetlands form the river's headwaters . The trench is a broad, deep, and long glacial valley between the Canadian Rockies and the Columbia Mountains in BC. For its first 200 mi (320 km), the Columbia flows northwest along the trench through Windermere Lake and the town of Invermere , a region known in BC as the Columbia Valley , then northwest to Golden and into Kinbasket Lake .

Native American stories about the bridge differ in their details but agree in general that the bridge permitted increased interaction between tribes on the north and south sides of the river. Horses, originally acquired from Spanish New Mexico , spread widely via native trade networks, reaching the Shoshone of the Snake River Plain by 1700. The Nez Perce, Cayuse, and Flathead people acquired their first horses around 1730. Along with horses came aspects of

7875-412: The base of Bonneville Dam , its head of tide . When the rifting of Pangaea , due to the process of plate tectonics , pushed North America away from Europe and Africa and into the Panthalassic Ocean (ancestor to the modern Pacific Ocean), the Pacific Northwest was not part of the continent. As the North American continent moved westward, the Farallon Plate subducted under its western margin. As

8000-494: The center of activity in the Pacific Northwest. Every year ships would come from London to drop off supplies and trade goods in exchange for the furs. It was the nexus for the fur trade on the Pacific Coast; its influence reached from the Rocky Mountains to the Hawaiian Islands , and from Russian Alaska into Mexican-controlled California . From Fort Vancouver, at its pinnacle, McLoughlin watched over 34 outposts, 24 ports, six ships, and 600 employees. Under McLoughlin's management,

8125-460: The center of an extensive trading network across the Pacific Plateau. Celilo was the oldest continuously inhabited community on the North American continent. Salmon canneries established by white settlers beginning in 1866 had a strong negative impact on the salmon population, and in 1908 US president Theodore Roosevelt observed that the salmon runs were but a fraction of what they had been 25 years prior. As river development continued in

8250-419: The coastal area around the mouth of the river in the late 18th century, trading with local natives. The contact would prove devastating to the indigenous Chinookan speaking peoples; a large portion of their population was wiped out by a smallpox epidemic. Canadian explorer Alexander Mackenzie crossed what is now interior British Columbia in 1793. From 1805 to 1806, the Lewis and Clark Expedition entered

8375-466: The company could mandate its factor to perform the functions of a governor, theoretically under authority of a higher echelon, including command of a small garrison. For example, Banten , on the Indonesian island of Java , was from 1603 to 1682 a trading post established by the East India Company and run by a series of chief factors. The term and its compounds are also used to render equivalent positions in other languages, such as: A debt factor, whether

8500-434: The confluence of the Columbia and Willamette Rivers . The site was chosen by Sir George Simpson . The post was opened for business on March 19, 1825. From his Columbia Department headquarters in Fort Vancouver, McLoughlin supervised trade and kept peace with the Indians, inaugurated salmon and timber trade with Mexican-controlled California and Hawaii , and supplied Russian America with produce. Fort Vancouver became

8625-449: The construction of a Goldendale-based pumped hydroelectric energy storage project. Jeremy Takala of the Yakama Nation embodies Yakama belief on the importance of Columbia River crops to food and medicine, stating "the [Goldendale] project being proposed here, it will definitely impact our life".  The Goldendale-pumped hydro storage unit could allow for reused water use in reservoirs, which would be placed on mountainous terrain overlooking

8750-414: The emerging plains culture , such as equestrian and horse training skills, greatly increased mobility, hunting efficiency, trade over long distances, intensified warfare, the linking of wealth and prestige to horses and war, and the rise of large and powerful tribal confederacies. The Nez Perce and Cayuse kept large herds and made annual long-distance trips to the Great Plains for bison hunting, adopted

8875-495: The final 309 mi (497 km) of its journey. The Deschutes River joins the Columbia near The Dalles . Between The Dalles and Portland , the river cuts through the Cascade Range , forming the dramatic Columbia River Gorge . Via the gorge, the Columbia crosses the Cascades at a lower elevation than any other river. The gorge is known for its strong and steady winds, scenic beauty, and its role as an important transportation link. The river continues west, bending sharply to

9000-452: The floodwaters slowed in the broad flats of the Quincy, Othello, and Pasco Basins. The floods' periodic inundation of the lower Columbia River Plateau deposited rich sediments; 21st-century farmers in the Willamette Valley "plow fields of fertile Montana soil and clays from Washington's Palouse". Over the last several thousand years a series of large landslides have occurred on the north side of

9125-563: The grievances John Sr. held against the company. After resigning from the Hudson's Bay Company in 1846, McLoughlin moved his family south to Oregon City in the Willamette Valley . The Oregon Treaty had been ratified by that time, and the region, now known as the Oregon Territory , was part of the United States. The valley was the destination of choice for settlers streaming in over the Oregon Trail . At his Oregon City store, he sold food and farming tools to settlers. In 1847, McLoughlin

9250-427: The idea that the landslide debris present today was formed by more than one slide is relatively recent and may explain the large range of estimates. It has been suggested that if the later dates are accurate there may be a link with the 1700 Cascadia earthquake . The pile of debris resulting from the Bonneville Slide blocked the river until rising water finally washed away the sediment. It is not known how long it took

9375-518: The jetties. In 1891, the Columbia was dredged to enhance shipping. The channel between the ocean and Portland and Vancouver was deepened from 17 feet (5.2 m) to 25 feet (7.6 m). The Columbian called for the channel to be deepened to 40 feet (12 m) as early as 1905, but that depth was not attained until 1976. Cascade Locks and Canal were first constructed in 1896 around the Cascades Rapids, enabling boats to travel safely through

9500-447: The largest run since 1938 was in 1986, with 3.2 million fish entering the Columbia. The annual catch by natives has been estimated at 42 million pounds (19,000 metric tons). The most important and productive native fishing site was located at Celilo Falls, which was perhaps the most productive inland fishing site in North America. The falls were located at the border between Chinookan- and Sahaptian-speaking peoples and served as

9625-526: The long-sought Northwest Passage. A 1798 British map showed a dotted line connecting the Columbia with the Missouri. When the American explorers Meriwether Lewis and William Clark charted the vast, unmapped lands of the American West in their overland expedition (1803–1805), they found no passage between the rivers. After crossing the Rocky Mountains , Lewis and Clark built dugout canoes and paddled down

9750-487: The lower Columbia and its tributaries, and dredging has opened, maintained, and enlarged shipping channels . Since the early 20th century, dams have been built across the river for power generation , navigation , irrigation , and flood control . The 14 hydroelectric dams on the Columbia's main stem and many more on its tributaries produce more than 44 percent of total U.S. hydroelectric generation . Production of nuclear power has taken place at two sites along

9875-495: The lucrative fur trade. Two developments in the late 1830s made a reappraisal of Hudson's Bay Company operations in the Columbia Department necessary. Apprehensions about American antagonism rose due to US Senator Lewis F. Linn , who in 1838 called for a naval force to be dispatched to the Columbia River, although the measure never passed. Favorable relations with the Russian-American Company (RAC) were established with

10000-489: The men portage around falls and unnavigable rapids; in return, the Indians were paid with trade goods. An 1839 report cites the travel time as three months and ten days—almost 26 miles (40 km) per day on average. The brigades used boat, horseback, and backpacks to bring the supplies in and furs out to the forts and trading posts along the route. The Hudson Bay Company officially discouraged settlement because it interfered with

10125-464: The mid- and lower Columbia were not tribal, but instead congregated in social units no larger than a village, and more often at a family level; these units would shift with the season as people moved about, following the salmon catch up and down the river's tributaries. Sparked by the 1847 Whitman Massacre , a number of violent battles were fought between American settlers and the region's natives. The subsequent wars over Northwest territory, especially

10250-580: The north-northwest near Portland and Vancouver, Washington , at the Willamette River confluence. Here the river slows considerably, dropping sediment that might otherwise form a river delta at the Columbia's mouth. Near Longview, Washington and the Cowlitz River confluence, the river turns west again. The Columbia empties into the Pacific Ocean just west of Astoria, Oregon , over the Columbia Bar ,

10375-794: The northern end of the Selkirk Mountains , the river turns sharply south through a region known as the Big Bend Country , passing through Revelstoke Lake and the Arrow Lakes . Revelstoke, the Big Bend, and the Columbia Valley combined are referred to in BC parlance as the Columbia Country . Below the Arrow Lakes, the Columbia passes the cities of Castlegar , located at the Columbia's confluence with

10500-433: The only survivors of the massacre of fifteen members of his exploring party by Umpqua people , who lived to the south in Oregon. McLoughlin sent a party headed by Alexander Roderick McLeod to recover Smith's property. In the early 1840s, with the arrival of the first wagon trains via the Oregon Trail , McLoughlin disobeyed company orders and extended substantial aid to the American settlers. Relations between Britain and

10625-477: The participation of British subjects in the government. Although the Oregon Treaty of 1846 settled the boundaries of US jurisdiction upon all lands south of the 49th parallel, the Provisional Government continued to function until 1849, when the first governor of Oregon Territory arrived. McLoughlin's first child, Joseph, was born in 1809. The name of Joseph's mother is unknown, but it is likely that she

10750-467: The plains culture to a significant degree, and became the main conduit through which horses and the plains culture diffused into the Columbia River region. Other peoples acquired horses and aspects of the plains culture unevenly. The Yakama, Umatilla, Palus, Spokane, and Coeur d'Alene maintained sizable herds of horses and adopted some of the plains cultural characteristics, but fishing and fish-related economies remained important. Less affected groups included

10875-532: The plate subducted, it carried along island arcs which were accreted to the North American continent, resulting in the creation of the Pacific Northwest between 150 and 90 million years ago. The general outline of the Columbia Basin was not complete until between 60 and 40 million years ago, but it lay under a large inland sea later subject to uplift. Between 50 and 20 million years ago, from

11000-688: The power plant. These harmful chemicals mainly consisted of aluminum. This event is commonly known today as the Salmon Scam . Shortly after the Salmon Scam, many Columbia River-based indigenous tribes received federally recognized status. The Siletz Tribe was the first to restore its federal recognition in 1977, followed by the Cow Creek Band of the Umpqua Tribe in 1982, the Grand Ronde Tribe in 1983,

11125-542: The principal arising out of the factor's activity. The term derives from the Latin for "doer, maker", from facit , "he/she/it does/makes". Historically, a factor had their seat at a sort of trading post known as a factory . Before the 20th century, factors were mercantile intermediaries whose main functions were warehousing and selling consigned goods, accounting to principals for the proceeds, guaranteeing buyers' credit, and sometimes making cash advances to principals prior to

11250-786: The rapid settlement and economic development of the region. Steamboats operated in several distinct stretches of the river: on its lower reaches, from the Pacific Ocean to Cascades Rapids; from the Cascades to the Dalles-Celilo Falls; from Celilo to Priests Rapids; on the Wenatchee Reach of eastern Washington; on British Columbia's Arrow Lakes ; and on tributaries like the Willamette , the Snake and Kootenay Lake . The boats, initially powered by burning wood, carried passengers and freight throughout

11375-460: The region for many years. Early railroads served to connect steamboat lines interrupted by waterfalls on the river's lower reaches. In the 1880s, railroads maintained by companies such as the Oregon Railroad and Navigation Company began to supplement steamboat operations as the major transportation links along the river. As early as 1881, industrialists proposed altering the natural channel of

11500-498: The region. Following Hezeta's reports, British maritime fur trader Captain John Meares searched for the river in 1788 but concluded that it did not exist. He named Cape Disappointment for the non-existent river, not realizing the cape marks the northern edge of the river's mouth. What happened next would form the basis for decades of both cooperation and dispute between British and American exploration of, and ownership claim to,

11625-627: The region. Royal Navy commander George Vancouver sailed past the mouth in April 1792 and observed a change in the water's color, but he accepted Meares' report and continued on his journey northward. Later that month, Vancouver encountered the American captain Robert Gray at the Strait of Juan de Fuca . Gray reported that he had seen the entrance to the Columbia and had spent nine days trying but failing to enter. On May 12, 1792, Gray returned south and crossed

11750-717: The region. For many the final leg of the journey involved travel down the lower Columbia River to Fort Vancouver. This part of the Oregon Trail, the treacherous stretch from The Dalles to below the Cascades, could not be traversed by horses or wagons (only watercraft, at great risk). This prompted the 1846 construction of the Barlow Road . In the Treaty of 1818 the United States and Britain agreed that both nations were to enjoy equal rights in Oregon Country for 10 years. By 1828, when

11875-562: The remaining seven families were sent to Fort Cowlitz . When three Japanese sailors, among them Otokichi , were shipwrecked on the Olympic Peninsula in 1834, McLoughlin thought they might present an opportunity to open trade with Japan . He sent the three men to London on the Eagle to try to convince the Crown of his plan. They reached London in 1835, probably the first Japanese to do so since

12000-462: The river he had not yet seen, becoming the first Euro-descended person to travel the entire length of the river. In 1825, the Hudson's Bay Company (HBC) established Fort Vancouver on the bank of the Columbia, in what is now Vancouver, Washington, as the headquarters of the company's Columbia District , which encompassed everything west of the Rocky Mountains, north of California, and south of Russian-claimed Alaska. Chief Factor John McLoughlin ,

12125-518: The river in 1792, proved that it was possible to cross the Columbia Bar. Many of the challenges associated with that feat remain today; even with modern engineering alterations to the mouth of the river, the strong currents and shifting sandbar make it dangerous to pass between the river and the Pacific Ocean. The use of steamboats along the river, beginning with the British Beaver in 1836 and followed by American vessels in 1850, contributed to

12250-451: The river ranks 23rd in length, and the Canadian part of its basin ranks 13th in size among Canadian basins. The Columbia shares its name with nearby places, such as British Columbia, as well as with landforms and bodies of water. With an average flow at the mouth of about 265,000 cu ft/s (7,500 m /s), the Columbia is the largest river by discharge flowing into the Pacific from

12375-479: The river to break through the barrier; estimates range from several months to several years. Much of the landslide's debris remained, forcing the river about 1.5 miles (2.4 km) south of its previous channel and forming the Cascade Rapids . In 1938, the construction of Bonneville Dam inundated the rapids as well as the remaining trees that could be used to refine the estimated date of the landslide. In 1980,

12500-635: The river's upper reaches in Canada. All three terms essentially mean "the big river". Oral histories describe the formation and destruction of the Bridge of the Gods , a land bridge that connected the Oregon and Washington sides of the river in the Columbia River Gorge. The bridge, which aligns with geological records of the Bonneville Slide, was described in some stories as the result of a battle between gods, represented by Mount Adams and Mount Hood , in their competition for

12625-405: The river, but nearly all the British colonists moved south to the Willamette Valley. The hope that the British colonists might dilute the American presence in the valley failed in the face of the overwhelming number of American settlers. These developments rekindled the issue of "joint occupation" and the boundary dispute . While some British interests, especially the Hudson's Bay Company, fought for

12750-600: The river. Later in 1792, William Robert Broughton of the British Royal Navy commanding HMS Chatham as part of the Vancouver Expedition , navigated past the Oregon Coast Range and 100 miles (160 km) upriver to what is now Vancouver, Washington. In the following decades, fur-trading companies used the Columbia as a key transportation route. Overland explorers entered the Willamette Valley through

12875-704: The river. Plutonium for nuclear weapons was produced for decades at the Hanford Site , which is now the most contaminated nuclear site in the United States. These developments have greatly altered river environments in the watershed, mainly through industrial pollution and barriers to fish migration. The Columbia begins its 1,243 mi (2,000 km) journey in the southern Rocky Mountain Trench in British Columbia (BC). Columbia Lake  –  2,690 ft (820 m) above sea level  –  and

13000-420: The route, ( Fort Vancouver in the Columbia District on the lower Columbia River and the other from York Factory on Hudson Bay ), that set out in spring and passed each other in the middle of the continent. Each brigade consisted of about forty to seventy-five men and two to five specially made boats that traveled at breakneck speed (for the time). These brigades often needed help from Indians, who would help

13125-416: The sale of the goods. Their services were of particular value in foreign trade, and factors became important figures in the great period of colonial exploration and development. A relatively large mercantile company could have a hierarchy including several grades of factor. The British East India Company hierarchy ranked "factors" between "writers" (junior clerks) and "junior merchants". In North America

13250-460: The scenic, but treacherous Columbia River Gorge , and pioneers began to settle the valley in increasing numbers. Steamships along the river linked communities and facilitated trade; the arrival of railroads in the late 19th century, many running along the river, supplemented these links. Since the late 19th century, public and private sectors have extensively developed the river. To aid ship and barge navigation, locks have been built along

13375-717: The signing of the RAC-HBC Agreement in 1839. To meet the new commercial obligations and to support British claims in the Oregon Question, the Hudson's Bay Company formally incorporated the Puget Sound Agricultural Company (PSAC) subsidiary in 1840. The new venture, while nominally independent, was administratively included within the Columbia Department. McLoughlin criticized the idea of a fur trading monopoly maintaining agricultural operations, as he felt independent farmers would be efficient. Nonetheless, he

13500-430: The so-called "joint occupation" was renewed indefinitely, it seemed probable that the lower Columbia River would in time become the border between the two nations. For years the Hudson's Bay Company successfully maintained control of the Columbia River and American attempts to gain a foothold were fended off. In the 1830s, American religious missions were established at several locations in the lower Columbia River region. In

13625-457: The total watershed. Flow rates on the Columbia are affected by many large upstream reservoirs, many diversions for irrigation, and, on the lower stretches, reverse flow from the tides of the Pacific Ocean. The National Ocean Service observes water levels at six tide gauges and issues tide forecasts for twenty-two additional locations along the river between the entrance at the North Jetty and

13750-532: The village. ) . At the time, the wives of many Hudson's Bay field employees were indigenous, including McLoughlin's own wife. John McLoughlin lost one son to a violent death. John McLoughlin, Jr. had been appointed the second Clerk in Charge at Fort Stikine , only to die in April 1842 at the hands of one of the fort employees, Urbain Heroux , who was charged with his murder but acquitted for lack of evidence, which added to

13875-661: The western border of the Spokane Indian Reservation . The river turns south after the Okanogan River confluence, then southeasterly near the confluence with the Wenatchee River in central Washington. This C-shaped segment of the river is also known as the "Big Bend". During the Missoula Floods 10–15,000 years ago, much of the floodwater took a more direct route south, forming the ancient river bed known as

14000-416: The winter of 1807–08 at Kootanae House near the source of the Columbia at present-day Invermere, BC. Over the next few years he explored much of the river and its northern tributaries. In 1811 he traveled down the Columbia to the Pacific Ocean, arriving at the mouth just after John Jacob Astor 's Pacific Fur Company had founded Astoria. On his return to the north, Thompson explored the one remaining part of

14125-706: Was Ojibwe . Around 1810, McLoughlin entered into a relationship with Marguerite Waddens McKay. McKay was the daughter of Jean-Étienne Waddens , who was one of the original partners of the North West Company, and an indigenous woman whose name is unknown. She was the widow of Alexander McKay , a trader killed in the Tonquin incident. Her son Thomas became McLoughlin's stepson. McLoughlin and McKay had four children: John Jr. , Elisabeth, Eloisa, and David. They were legally married in 1842 at Fort Vancouver. McLoughlin's appearance, 6 foot 4 inches (193 cm) tall with long, prematurely white hair, brought him respect; but he

14250-559: Was 1,240,000 cu ft/s (35,000 m /s) in June 1894, before the river was dammed. The lowest flow recorded at The Dalles was 12,100 cu ft/s (340 m /s) on April 16, 1968, and was caused by the initial closure of the John Day Dam , 28 mi (45 km) upstream. The Dalles is about 190 mi (310 km) from the mouth; the river at this point drains about 237,000 sq mi (610,000 km ) or about 91 percent of

14375-470: Was Grays Bay at the mouth of Grays River . Gray's discovery of the Columbia River was later used by the United States to support its claim to the Oregon Country, which was also claimed by Russia , Great Britain , Spain and other nations. In October 1792, Vancouver sent Lieutenant William Robert Broughton , his second-in-command, up the river. Broughton got as far as the Sandy River at the western end of

14500-426: Was also generally known for his fair treatment of the people with whom he dealt, whether they were British subjects, U.S. citizens, or of indigenous origin (notwithstanding for example, his asymmetric use of force against the S'Klallam tribe after an earlier raid--an HBC ship under his command fired its cannons into an unrelated village near Port Townsend in the early morning, killing twenty-seven people and leveling

14625-472: Was appointed as the PSAC supervisor. The fertile plains near the Cowlitz River were selected as a suitable location for Cowlitz Farm , the principal PSAC farm. Fort Nisqually was also assigned to the PSAC, where numerous livestock herds were maintained. Several locations were considered for potential farmers, including among the French Canadian and Métis farmers of the Willamette Valley, Scotland , and

14750-415: Was appointed to assist him. At the time, the region was under joint occupation of both the United States and Britain pursuant to the Treaty of 1818 . Upon his arrival, McLoughlin determined that the headquarters of the company at Fort Astoria (now Astoria , Oregon ), at the mouth of the Columbia River , was unfit. The York Factory Express trade route had evolved from an earlier express brigade used by

14875-521: Was completed in 1975. Among the main commodities are wheat and other grains, mainly for export. As of 2016, the Columbia ranked third, behind the Mississippi and Paraná rivers, among the world's largest export corridors for grain. The 1980 eruption of Mount St. Helens caused mudslides in the area, which reduced the Columbia's depth by 25 feet (7.6 m) for a 4-mile (6.4 km) stretch, disrupting Portland's economy. Efforts to maintain and improve

15000-605: Was entitled to possess and/or study the remains. Many different Native Americans and First Nations peoples have a historical and continuing presence on the Columbia. South of the Canada–US ;border, the Colville , Spokane , Coeur d'Alene , Yakama , Nez Perce , Cayuse , Palus , Umatilla , Cowlitz , and the Confederated Tribes of Warm Springs live along the US stretch. Along the upper Snake River and Salmon River ,

15125-617: Was famous as the last stop on the Oregon Trail . McLoughlin was born in October 1784 in Rivière-du-Loup , Quebec , and was of Scottish and French Canadian descent. He lived with his great uncle, Colonel William Fraser, for a while as a child. Though baptized Roman Catholic , he was raised Anglican . In his later life, he returned to the Roman Catholic faith. In 1798, he began to study medicine under Sir James Fisher of Quebec. McLoughlin

15250-561: Was given the Knighthood of St. Gregory , bestowed on him by Pope Gregory XVI . He became a U.S. citizen in 1849. McLoughlin's opponents succeeded in inserting a clause forfeiting his land claim in the Donation Land Claim Act of 1850 by Samuel R. Thurston . Although it was never enforced, it embittered the elderly McLoughlin. He served as mayor of Oregon City in 1851, winning 44 of 66 votes. He died of natural causes in 1857. His grave

15375-460: Was granted a licence to practice medicine in Lower Canada (now Quebec) in 1803. He evidently completed his course, as he is widely referred to as "Dr. John McLoughlin". McLoughlin was hired as a physician at Fort William , the inland headquarters and a fur trade post of the North West Company on Lake Superior . There he became a trader and mastered several Indian languages. In 1814, he became

15500-532: Was instrumental in the negotiations leading to the North West Company's 1821 merger with the Hudson's Bay Company. He was promoted to head the Lac la Pluie district temporarily shortly after the merger. In 1824, the Hudson's Bay Company appointed McLoughlin, already a Chief Factor , as Superintendent of the Columbia Department (roughly parallel to what Americans know as the Oregon Country ), and Peter Skene Ogden

15625-472: Was submerged by the construction of The Dalles Dam, and the native fishing community was displaced. The affected tribes received a $ 26.8 million settlement for the loss of Celilo and other fishing sites submerged by The Dalles Dam. The Confederated Tribes of Warm Springs used part of its $ 4 million settlement to establish the Kah-Nee-Ta resort south of Mount Hood. In 1977, 75 indigenous fishermen of
