United States
The United States of America (U.S.A. or USA), commonly known as the United States (U.S. or US) or America, is a country primarily located in North America. It consists of 50 states, a federal district, five major unincorporated territories, nine Minor Outlying Islands, and 326 Indian reservations. The United States is also in free association with three Pacific Island sovereign states: the Federated States of Micronesia, the Marshall Islands, and the Republic of Palau.

Discharge (hydrology)
In hydrology, discharge is the volumetric flow rate of water that is transported through a given cross-sectional area. It includes any suspended solids (e.g. sediment), dissolved chemicals (e.g. CaCO3(aq)), or biologic material (e.g. diatoms) in addition to the water itself. Terms may vary between disciplines. For example, a fluvial hydrologist studying natural river systems may define discharge as streamflow, whereas an engineer operating a reservoir system may equate it with outflow, contrasted with inflow. Theory and calculation A discharge is a measure of the quantity of any fluid flow over unit time. The quantity may be either volume or mass. Thus the water discharge of a tap (faucet) can be measured with a measuring jug and a stopwatch. Here the discharge might be 1 litre per 15 seconds, equivalent to 67 ml/second or 4 litres/minute. This is an average measure. For measuring the discharge of a river we need a different method and the most common is the 'area-velocity' method. ...

Since the establishment of a world fur market in the early modern period, furs of boreal, polar and cold temperate mammalian animals have been the most ... district in the Pacific Northwest region of British North America in the 19th century. Much of its territory overlapped with the disputed Oregon Country. It was explored by the North West Company between 1793 and 1811, and established as an operating fur district around 1810. The North West Company was absorbed into the Hudson's Bay Company in 1821 under which the Columbia District became known as the Columbia Department. The Oregon Treaty of 1846 marked the effective end of the Hudson's Bay Company's Columbia Department. Early years Beginning in 1807, David Thompson (explorer), David Thompson, working for the North West Company (NWC), explored much of what would become the Columbia Distr ...

Hudson's Bay Company
The Hudson's Bay Company (HBC; french: Compagnie de la Baie d'Hudson) is a Canadian retail business group. A fur trading business for much of its existence, HBC now owns and operates retail stores in Canada. The company's namesake business division is Hudson's Bay, commonly referred to as The Bay ( in French). After incorporation by English royal charter in 1670, the company functioned as the ''de facto'' government in parts of North America for nearly 200 years until the HBC sold the land it owned (the entire Hudson Bay drainage basin, known as Rupert's Land) to Canada in 1869 as part of the Deed of Surrender, authorized by the Rupert's Land Act 1868. At its peak, the company controlled the fur trade throughout much of the English- and later British-controlled North America. By the mid-19th century, the company evolved into a mercantile business selling a wide variety of products from furs to fine homeware in a small number of sales shops (as opposed to trading posts) acros ...

Treaty Of 1818
The Convention respecting fisheries, boundary and the restoration of slaves, also known as the London Convention, Anglo-American Convention of 1818, Convention of 1818, or simply the Treaty of 1818, is an international treaty signed in 1818 between the United States and the United Kingdom. This treaty resolved standing boundary issues between the two nations. The treaty allowed for joint occupation and settlement of the Oregon Country, known to the British and in Canadian history as the Columbia District of the Hudson's Bay Company, and including the southern portion of its sister district New Caledonia (Canada), New Caledonia. The two nations agreed to a boundary line involving the 49th parallel north, in part because a straight-line boundary would be easier to survey than the pre-existing boundaries based on watersheds. The treaty marked both the United Kingdom's last permanent major loss of territory in what is now the Continental United States and the United States' first per ...

Oregon Treaty
The Oregon Treaty is a treaty between the United Kingdom and the United States that was signed on June 15, 1846, in Washington, D.C. The treaty brought an end to the Oregon boundary dispute by settling competing American and British claims to the Oregon Country; the area had been Condominium (international law), jointly occupied by both Britain and the U.S. since the Treaty of 1818. Background The Treaty of 1818 set the boundary between the United States and British North America along the 49th parallel north, 49th parallel of north latitude from Minnesota to the "Stony Mountains" (now known as the Rocky Mountains). The region west of those mountains was known to the Americans as the Oregon Country and to the British as the Columbia Department or Columbia District of the Hudson's Bay Company. (Also included in the region was the southern portion of another fur district, New Caledonia (Canada), New Caledonia.) The treaty provided for joint control of that land for ten years. ...

Fur Trade
The fur trade is a worldwide industry dealing in the acquisition and sale of animal fur. Since the establishment of a world fur market in the early modern period, furs of boreal, polar and cold temperate mammalian animals have been the most valued. Historically the trade stimulated the exploration and colonization of Siberia, northern North America, and the South Shetland and South Sandwich Islands. Today the importance of the fur trade has diminished; it is based on pelts produced at fur farms and regulated fur-bearer trapping, but has become controversial. Animal rights organizations oppose the fur trade, citing that animals are brutally killed and sometimes skinned alive. Fur has been replaced in some clothing by synthetic imitations, for example, as in ruffs on hoods of parkas. Continental fur trade Russian fur trade Before the European colonization of the Americas, Russia was a major supplier of fur pelts to Western Europe and parts of Asia. Its trade developed in ...

Fort Nez Percés
Fort Nez Percés (or Fort Nez Percé, with or without the accent aigu), later known as (Old) Fort Walla Walla, was a fortified fur trading post on the Columbia River on the territory of modern-day Wallula, Washington. Despite being named after the Nez Perce people, the fort was in the traditional lands of the Walla Walla. Founded in 1818 by the North-West Company, after 1821 it was run by the Hudson's Bay Company until its closure in 1857. North West Company During David Thompson's 1811 voyage down the Columbia River, he camped at the confluence with the Snake River on July 9, 1811. He erected a pole and a notice claiming the country for Great Britain and stating the intention of the North West Company to build a trading post at the site. North West Company managers during an annual meeting in Fort William, gave instructions for a fort to be created near the mouth of the Walla Walla River, a few miles south of the confluence of the Snake and the Columbia.

David Thompson (explorer)
David Thompson (30 April 1770 – 10 February 1857) was a English Canadian, British-Canadian fur trader, surveying, surveyor, and Cartography, cartographer, known to some native people as "Koo-Koo-Sint" or "the Stargazer". Over Thompson's career, he travelled across North America, mapping of North America along the way. For this historic feat, Thompson has been described as the "greatest practical land geographer that the world has produced". Early life David Thompson was born in Westminster, Middlesex, to recent Welsh migrants David and Ann Thompson. When Thompson was two, his father died. Due to the financial hardship with his mother without resources, Thompson, 29 April 1777, the day before his seventh birthday, and his older brother were placed in the Grey Coat Hospital, a school for the disadvantaged of Westminster. Thompson graduated to the Grey Coat mathematical school, well known for teaching navigation and surveying. He received an education for the Royal Navy: inclu ...

Snake River
The Snake River is a major river of the greater Pacific Northwest region in the United States. At long, it is the largest tributary of the Columbia River, in turn, the largest North American river that empties into the Pacific Ocean. The Snake River rises in western Wyoming, then flows through the Snake River Plain of southern Idaho, the rugged Hells Canyon on the Oregon–Idaho border and the rolling Palouse Hills of Washington (state), Washington, emptying into the Columbia River at the Tri-Cities, Washington, Tri-Cities in the Columbia Basin of Eastern Washington. The Snake River drainage basin encompasses parts of six U.S. states (Idaho, Washington, Oregon, Utah, Nevada, and Wyoming) and is known for its varied geologic history. The Snake River Plain was created by a volcanic hotspot (geology), hotspot which now lies underneath the Snake River headwaters in Yellowstone National Park.

Lewis And Clark Expedition
The Lewis and Clark Expedition, also known as the Corps of Discovery Expedition, was the United States expedition to cross the newly acquired western portion of the country after the Louisiana Purchase. The Corps of Discovery was a select group of U.S. Army and civilian volunteers under the command of Captain Meriwether Lewis and his close friend Second Lieutenant William Clark. Clark and 30 members set out from Camp Dubois, Illinois, on May 14, 1804, met Lewis and ten other members of the group in St. Charles, Missouri, then went up the Missouri River. The expedition crossed the Continental Divide of the Americas near the Lemhi Pass, eventually coming to the Columbia River, and the Pacific Ocean in 1805. The return voyage began on March 23, 1806, at Fort Clatsop, Oregon, and ended on September 23 of the same year. President Thomas Jefferson commissioned the expedition shortly after the Louisiana Purchase in 1803 to explore and to map the newly acquired territory, to find a pr ...
