Missoula, Montana
–
Missoula /mᵻˈzuːlə/ is a city in the U. S. state of Montana and is the county seat of Missoula County. In 2015, the United States Census Bureau estimated the population at 71,022. In the 1990s, Missoula overtook Great Falls as Montana’s second‑largest city, Missoula is home to the University of Montana, a public research university. Missoula was founded in 1860 as Hellgate Trading Post while still part of Washington Territory, by 1866, the settlement had moved east,5 miles upstream, and renamed Missoula Mills, later shortened to Missoula. The mills provided supplies to settlers traveling along the Mullan Road. The establishment of Fort Missoula in 1877 to protect settlers further stabilized the economy, the arrival of the Northern Pacific Railway in 1883 brought rapid growth and the maturation of the local lumber industry. In 1893, the Montana Legislature chose the city as the site for the states first university, along with the U. S. Forest Service headquarters founded in 1908, lumber and the university remained staples of the local economy for the next hundred years. The city is governed by a government with twelve city council members. Notable residents include the first woman in the U. S. Congress, Jeannette Rankin, archaeological artifacts date the Missoula Valleys earliest inhabitants to the end of the last ice age 12,000 years ago with settlements as early as 3500 BCE. From the 1700s until European settlements began a years later, it was primarily the Salish, Kootenai, Pend dOreille, Blackfeet. Hell Gate would remain the name of the area until it was renamed Missoula in 1866, the Lewis and Clark Expedition brought the first U. S. citizens to the area. They twice stopped just south of Missoula at Travelers Rest and they camped there the first time on their westbound trip in September 1805. When they stayed there again on their return in June–July 1806, Clark left heading south along the Bitterroot River and Lewis traveled north, then east, through Hellgate Canyon. The desire for a more convenient water supply to power a lumber, the Missoula Mills replaced Hell Gate Village as the economic power of the valley and replaced it as the county seat in 1866. The name Missoula came from the Salish name for the Clark Fork River, nmesuletkw, Fort Missoula was established in 1877 to help protect further arriving settlers. Growth accelerated with the arrival of the Northern Pacific Railway in 1883, in 1893, Missoula was chosen as the location of the states first university, the University of Montana. The continued economic windfall from railroad construction and lumber mills led to a boom in Missoulas population. A. B. Hammond and Copper Kings Marcus Daly and William A. Clark competed fiercely in the region over lumber share, the United States Forest Service work in Missoula began in 1905

United States
–
Forty-eight of the fifty states and the federal district are contiguous and located in North America between Canada and Mexico. The state of Alaska is in the northwest corner of North America, bordered by Canada to the east, the state of Hawaii is an archipelago in the mid-Pacific Ocean. The U. S. territories are scattered about the Pacific Ocean, the geography, climate and wildlife of the country are extremely diverse. At 3.8 million square miles and with over 324 million people, the United States is the worlds third- or fourth-largest country by area, third-largest by land area. It is one of the worlds most ethnically diverse and multicultural nations, paleo-Indians migrated from Asia to the North American mainland at least 15,000 years ago. European colonization began in the 16th century, the United States emerged from 13 British colonies along the East Coast. Numerous disputes between Great Britain and the following the Seven Years War led to the American Revolution. On July 4,1776, during the course of the American Revolutionary War, the war ended in 1783 with recognition of the independence of the United States by Great Britain, representing the first successful war of independence against a European power. The current constitution was adopted in 1788, after the Articles of Confederation, the first ten amendments, collectively named the Bill of Rights, were ratified in 1791 and designed to guarantee many fundamental civil liberties. During the second half of the 19th century, the American Civil War led to the end of slavery in the country. By the end of century, the United States extended into the Pacific Ocean. The Spanish–American War and World War I confirmed the status as a global military power. The end of the Cold War and the dissolution of the Soviet Union in 1991 left the United States as the sole superpower. The U. S. is a member of the United Nations, World Bank, International Monetary Fund, Organization of American States. The United States is a developed country, with the worlds largest economy by nominal GDP. It ranks highly in several measures of performance, including average wage, human development, per capita GDP. While the U. S. economy is considered post-industrial, characterized by the dominance of services and knowledge economy, the United States is a prominent political and cultural force internationally, and a leader in scientific research and technological innovations. In 1507, the German cartographer Martin Waldseemüller produced a map on which he named the lands of the Western Hemisphere America after the Italian explorer and cartographer Amerigo Vespucci

Montana
–
Montana /mɒnˈtænə/ is a state in the Western region of the United States. The states name is derived from the Spanish word montaña, Montana has several nicknames, although none official, including Big Sky Country and The Treasure State, and slogans that include Land of the Shining Mountains and more recently The Last Best Place. Montana has a 545-mile border with three Canadian provinces, British Columbia, Alberta, and Saskatchewan, the state to do so. It also borders North Dakota and South Dakota to the east, Wyoming to the south, Montana is ranked 4th in size, but 44th in population and 48th in population density of the 50 United States. The western third of Montana contains numerous mountain ranges, smaller island ranges are found throughout the state. In total,77 named ranges are part of the Rocky Mountains, the eastern half of Montana is characterized by western prairie terrain and badlands. The economy is based on agriculture, including ranching and cereal grain farming. Other significant economic activities include oil, gas, coal and hard rock mining, lumber, the health care, service, and government sectors also are significant to the states economy. Millions of tourists annually visit Glacier National Park, the Little Bighorn Battlefield National Monument, the name Montana comes from the Spanish word Montaña and the Latin word Montana, meaning mountain, or more broadly, mountainous country. Montaña del Norte was the name given by early Spanish explorers to the mountainous region of the west. The name was changed by Representatives Henry Wilson and Benjamin F. Harding, when Ashley presented a bill to establish a temporary government in 1864 for a new territory to be carved out of Idaho, he again chose Montana Territory. This time Rep. Samuel Cox, also of Ohio, objected to the name, Cox complained that the name was a misnomer given most of the territory was not mountainous and that a Native American name would be more appropriate than a Spanish one. Other names such as Shoshone were suggested, but it was decided that the Committee on Territories could name it whatever they wanted, with an area of 147,040 square miles, Montana is slightly larger than Japan. It is the fourth largest state in the United States after Alaska, Texas, and California, the largest landlocked U. S. state, and the worlds 56th largest national state/province subdivision. To the north, Montana shares a 545-mile border with three Canadian provinces, British Columbia, Alberta, and Saskatchewan, the state to do so. It borders North Dakota and South Dakota to the east, Wyoming to the south, the states topography is roughly defined by the Continental Divide, which splits much of the state into distinct eastern and western regions. Most of Montanas 100 or more named mountain ranges are in the western half. The Absaroka and Beartooth ranges in the states south-central part are part of the Central Rocky Mountains

Idaho
–
Idaho is a state in the northwestern region of the United States. It borders the state of Montana to the east and northeast, Wyoming to the east, Nevada and Utah to the south, to the north, it shares a small portion of the Canadian border with the province of British Columbia. With a population of around 1.7 million people and an area of 83,569 square miles, Idaho is the 14th largest, the states capital and largest city is Boise. Idaho prior to European settlement was inhabited solely by Native American peoples, in the early 19th century, Idaho was considered part of the Oregon Country, an area disputed between the U. S. and the United Kingdom. Idaho was eventually admitted to the Union on July 3,1890, forming part of the Pacific Northwest, Idaho is divided into several distinct geographic and climatic regions. In the states north, the relatively isolated Idaho Panhandle is closely linked with Eastern Washington, the states south includes the Snake River Plain, while the south-east incorporates part of the Great Basin. Idaho is quite mountainous, and contains several stretches of the Rocky Mountains, additionally, around 38 percent of Idahos land is held by the United States Forest Service, the most of any state. Industries significant for the economy include manufacturing, agriculture, mining, forestry. Idahos agricultural sector supplies a number of different products, but the state is best known for its potato crop, the official state nickname is the Gem State, which references Idahos reputation for gemstones and, more broadly, its many wilderness areas. The exact origin of the remains a mystery. Willing later claimed that he had invented the name. Congress ultimately decided to name the area Colorado Territory when it was created in February 1861, thinking they would get a jump on the name, locals named a community in Colorado Idaho Springs. However, the name Idaho did not fall into obscurity, the same year Congress created Colorado Territory, a county called Idaho County was created in eastern Washington Territory. The county was named after a steamship named Idaho, which was launched on the Columbia River in 1860 and it is unclear whether the steamship was named before or after Willings claim was revealed. Regardless, a portion of Washington Territory, including Idaho County, was used to create Idaho Territory in 1863. Despite this lack of evidence for the origin of the name, the name Idaho may be derived from the Plains Apache word ídaahę́, which means enemy. The Comanches used this word to refer to the Idaho Territory, a 1956 Idaho history textbook says, Idaho is a Shoshoni Indian exclamation. The word consists of three parts, the first is Ee, which in English conveys the idea of coming down

Bitterroot River
–
The Bitterroot River is a tributary of the Clark Fork River in southwestern Montana, United States. It runs for about 75 miles south-to-north through the Bitterroot Valley, although the Bitterroot River passes close by to many residential areas, it is an excellent place for wildlife viewing. Many species of ducks and waterfowl are common along with osprey, bald eagles, both white-tailed deer and mule deer frequent the river as a source of water and to graze near its banks. The most notable wildlife viewing locale along the river is the famous Lee Metcalf National Wildlife Refuge, the Bitterroot is a Class I river from the confluence of the East and West forks to its confluence with the Clark Fork River for public access for recreational purposes.

Rocky Mountains
–
The Rocky Mountains, commonly known as the Rockies, are a major mountain range in western North America. The Rocky Mountains stretch more than 3,000 miles from the northernmost part of British Columbia, in western Canada, to New Mexico, in the Southwestern United States. Within the North American Cordillera, the Rockies are somewhat distinct from the Pacific Coast Ranges, the Rocky Mountains were initially formed from 80 million to 55 million years ago during the Laramide orogeny, in which a number of plates began to slide underneath the North American plate. The angle of subduction was shallow, resulting in a belt of mountains running down western North America. Since then, further tectonic activity and erosion by glaciers have sculpted the Rockies into dramatic peaks, at the end of the last ice age, humans started to inhabit the mountain range. The first mention of their present name by a European was in the journal of Jacques Legardeur de Saint-Pierre in 1752, the Rocky Mountains are commonly defined as stretching from the Liard River in British Columbia south to the Rio Grande in New Mexico. The United States definition of the Rockies includes the Cabinet and Salish Mountains of Idaho and their counterparts north of the Kootenai River, the Columbia Mountains, are considered a separate system in Canada, lying to the west of the huge Rocky Mountain Trench. This runs the length of British Columbia from its beginnings in the middle Flathead River valley in western Montana to the bank of the Liard River. The Rockies vary in width from 70 to 300 miles, also west of the Rocky Mountain Trench, farther north and facing the Muskwa Range across the trench, are the Stikine Ranges and Omineca Mountains of the Interior Mountains system of British Columbia. A small area east of Prince George, British Columbia on the side of the Trench. In Canada geographers define three main groups of ranges, the Continental Ranges, Hart Ranges and Muskwa Ranges, the Muskwa and Hart Ranges together comprise what is known as the Northern Rockies. The western edge of the Rockies includes ranges such as the Wasatch near Salt Lake City, the Great Basin and Columbia River Plateau separate these sub-ranges from distinct ranges further to the west, most prominent among which are the Sierra Nevada, Cascade Range and Coast Mountains. The Rocky Mountain System within the United States is a United States physiographic region, the Rocky Mountains are notable for containing the highest peaks in central North America. The ranges highest peak is Mount Elbert located in Colorado at 14,440 feet above sea level, Mount Robson in British Columbia, at 12,972 feet, is the highest peak in the Canadian Rockies. The Continental Divide of the Americas is located in the Rocky Mountains, triple Divide Peak in Glacier National Park is so named because water that falls on the mountain reaches not only the Atlantic and Pacific, but Hudson Bay as well. Farther north in Alberta, the Athabasca and other rivers feed the basin of the Mackenzie River, see Rivers of the Rocky Mountains for a list of rivers. Human population is not very dense in the Rocky Mountains, with an average of four people per square kilometer, however, the human population grew rapidly in the Rocky Mountain states between 1950 and 1990. The 40-year statewide increases in range from 35% in Montana to about 150% in Utah

Columbia River
–
The Columbia River is the largest river in the Pacific Northwest region of North America. The river rises in the Rocky Mountains of British Columbia, Canada and it flows northwest and then south into the US state of Washington, then turns west to form most of the border between Washington and the state of Oregon before emptying into the Pacific Ocean. The river is 1,243 miles long, and its largest tributary is the Snake River and its drainage basin is roughly the size of France and extends into seven US states and a Canadian province. By volume, the Columbia is the fourth-largest river in the United States, the rivers heavy flow and relatively steep gradient gives it tremendous potential for the generation of electricity. The Columbia and its tributaries have been central to the regions culture and they have been used for transportation since ancient times, linking the many cultural groups of the region. The river system hosts many species of fish, which migrate between freshwater habitats and the saline waters of the Pacific Ocean. In the following decades, fur trading companies used the Columbia as a key transportation route, 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 developed the river. The development, commonly referred to as taming or harnessing of the river, has been massive, to aid ship and barge navigation, locks have been built along 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 the purposes of power generation, navigation, irrigation, and flood control. Today, a reservoir lies along nearly every US mile of the once free-flowing river. Production of nuclear power has taken place at two sites along the river, plutonium for nuclear weapons was produced for decades at the Hanford Site, which is now the most contaminated nuclear site in the US. All these developments have had a impact on river environments, mainly through industrial pollution. The Columbia begins its 1, 243-mile journey in the southern Rocky Mountain Trench in British Columbia, Columbia Lake –2,690 feet above sea level – and the adjoining Columbia Wetlands form the rivers headwaters. The trench is a broad, deep, and long glacial valley between the Canadian Rockies and the Columbia Mountains in BC. Rounding the northern end of the Selkirk Mountains, the river turns south through a region known as the Big Bend Country, passing through Revelstoke Lake. 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 Columbias confluence with the Kootenay River, the Pend Oreille River joins the Columbia about 2 miles north of the US–Canada border

Pend Oreille River
–
In its passage through British Columbia its name is spelled Pend-dOreille River. It drains an area of the Rocky Mountains along the U. S. -Canada border on the east side of the Columbia. The river is defined as the lower part of the Clark Fork. The full drainage basin of the river and its tributaries accounts for 43% of the entire Columbia River Basin above the confluence with the Columbia, the total area of the Pend Oreille basin is just under 10% of the entire 258, 000-square-mile Columbia Basin. The Pend Oreille River begins at Lake Pend Oreille in Bonner County, Idaho in the Idaho Panhandle and it flows west, receiving the Priest River from the north at the town of Priest River, then flows into southern Pend Oreille County in northeastern Washington at Newport. Once in Washington it turns north, flowing along the side of the Selkirk Mountains. It flows roughly parallel to the Idaho border for approximately 50 miles, through the Colville National Forest, past Tiger and Metaline Falls. Much of the drainage divide of the watershed forms the border of Idaho and Montana. The river is considered as one with the Clark Fork. For example, in Stewart Holbrooks book The Columbia, he refers to the Pend Oreille River as the Clark Fork. S. Border south of Montrose, British Columbia and this makes the Pend Oreille system the second longest tributary of the Columbia River. It is the fourth largest by discharge and drains the second largest area, the Pend Oreille River watershed divide is formed on the east side by the Continental Divide. On the south, the Spokane River and Snake River drainage basins border on the Clark Fork, to the west smaller rivers such as the Colville River and tributaries of the Spokane drain the lands past the watershed divide. In the north is the Kootenay River, a tributary of the Columbia. To the east, in Montana, is the Missouri River and tributaries such as the Marias River, in the southwest the watershed borders on the Big Hole River and Jefferson River, headwater streams of the Missouri. The Pend Oreille/Clark Fork system is notable in that it right between the Bitterroot Range and Selkirk Range, two major chains of the Rocky Mountains. The only other river to do so is the Kootenay, just to the north, the Rocky Mountain Trench runs across the northeast part of the watershed, through the Flathead Valley, and eventually terminating in mountains near the Clark Forks confluence with the Flathead. The Pend Oreille River starts in northern Idaho, at Lake Pend Oreille, cocolalla Creek is the first major tributary

Washington (state)
–
It was admitted to the Union as the 42nd state in 1889. Washington is sometimes referred to as Washington State or the State of Washington to distinguish it from Washington, Washington is the 18th largest state with an area of 71,362 square miles, and the 13th most populous state with over 7 million people. Washington is the second most populous state on the West Coast and in the Western United States, Mount Rainier, an active stratovolcano, is the states highest elevation at almost 14,411 feet and is the most topographically prominent mountain in the contiguous United States. Washington is a leading lumber producer and its rugged surface is rich in stands of Douglas fir, hemlock, ponderosa pine, white pine, spruce, larch, and cedar. Manufacturing industries in Washington include aircraft and missiles, shipbuilding and other equipment, lumber, food processing, metals and metal products, chemicals. Washington has over 1,000 dams, including the Grand Coulee Dam, built for a variety of purposes including irrigation, power, flood control, the Washington Territory was named after George Washington, the first President of the United States. The area was part of a region called the Columbia District after the Columbia River. The area was renamed Washington in order to avoid confusion with the District of Columbia, Washington is the only U. S. state named after a president. To distinguish it from the U. S. capital, which is named for George Washington, Washington is sometimes referred to as Washington State, or, in more formal contexts. Washingtonians and other residents of the Pacific Northwest refer to the state simply as Washington, calling the nations capital Washington, D. C. or, often, Washington is the northwestern-most state of the contiguous United States. Washington is bordered by Oregon to the south, with the Columbia River forming the western part, to the west of Washington lies the Pacific Ocean. The high mountains of the Cascade Range run north-south, bisecting the state, from the Cascade Mountains westward, Western Washington has a mostly marine west coast climate, with mild temperatures and wet winters, autumns and springs, and relatively dry summers. The Cascade Range contains several volcanoes, which reach altitudes significantly higher than the rest of the mountains, from the north to the south, these major volcanoes are Mount Baker, Glacier Peak, Mount Rainier, Mount St. Helens, and Mount Adams. Mount Rainier, the tallest mountain in the state, is 50 miles south of the city of Seattle and it is also covered with more glacial ice than any other peak in the contiguous 48 states. Western Washington also is home of the Olympic Mountains, far west on the Olympic Peninsula and these deep forests, such as the Hoh Rainforest, are among the only temperate rainforests in the continental United States. Eastern Washington – the part of the state east of the Cascades – has a dry climate. It includes large areas of steppe and a few truly arid deserts lying in the rain shadow of the Cascades. Farther east, the climate becomes less arid, with annual rainfall increasing as one goes east to 21.2 inches in Pullman, the Okanogan Highlands and the rugged Kettle River Range and Selkirk Mountains cover much of the northeastern quadrant of the state

British Columbia
–
British Columbia is the westernmost province of Canada, with a population of more than four million people located between the Pacific Ocean and the Rocky Mountains. British Columbia is also a component of the Pacific Northwest and the Cascadia bioregion, along with the U. S. states of Idaho, Oregon, Washington and Alaska. The first British settlement in the area was Fort Victoria, established in 1843, subsequently, on the mainland, the Colony of British Columbia was founded by Richard Clement Moody and the Royal Engineers, Columbia Detachment, in response to the Fraser Canyon Gold Rush. Port Moody is named after him, in 1866, Vancouver Island became part of the colony of British Columbia, and Victoria became the united colonys capital. In 1871, British Columbia became the province of Canada. Its Latin motto is Splendor sine occasu, the capital of British Columbia remains Victoria, the fifteenth-largest metropolitan region in Canada, named for the Queen who created the original European colonies. The largest city is Vancouver, the third-largest metropolitan area in Canada, the largest in Western Canada, in October 2013, British Columbia had an estimated population of 4,606,371. British Columbia evolved from British possessions that were established in what is now British Columbia by 1871, First Nations, the original inhabitants of the land, have a history of at least 10,000 years in the area. Today there are few treaties and the question of Aboriginal Title, notably, the Tsilhqotin Nation has established Aboriginal title to a portion of their territory, as a result of the recent Supreme Court of Canada decision. BCs economy is diverse, with service producing industries accounting for the largest portion of the provinces GDP and it is the endpoint of transcontinental railways, and the site of major Pacific ports that enable international trade. Though less than 5% of its vast 944,735 km2 land is arable and its climate encourages outdoor recreation and tourism, though its economic mainstay has long been resource extraction, principally logging, farming, and mining. Vancouver, the provinces largest city and metropolitan area, also serves as the headquarters of many western-based natural resource companies and it also benefits from a strong housing market and a per capita income well above the national average. The Northern Interior region has a climate with very cold winters. The climate of Vancouver is by far the mildest winter climate of the major Canadian cities, the provinces name was chosen by Queen Victoria, when the Colony of British Columbia, i. e. the Mainland, became a British colony in 1858. The current southern border of British Columbia was established by the 1846 Oregon Treaty, British Columbias land area is 944,735 square kilometres. British Columbias rugged coastline stretches for more than 27,000 kilometres and it is the only province in Canada that borders the Pacific Ocean. British Columbias capital is Victoria, located at the tip of Vancouver Island. Only a narrow strip of the Island, from Campbell River to Victoria, is significantly populated, much of the western part of Vancouver Island and the rest of the coast is covered by thick, tall and sometimes impenetrable temperate rainforest

Interstate 90
–
Interstate 90 is a transcontinental freeway, and the longest Interstate Highway in the United States at 3,020.54 miles. Its western terminus is in Seattle, at Edgar Martinez Drive S. near Safeco Field and CenturyLink Field, I-90 crosses the Continental Divide over Homestake Pass just east of Butte, Montana. East of the Wisconsin-Illinois border, much of I-90 follows several toll roads, the Interstate is not tolled through some segments in downtown Chicago, Greater Cleveland, and the rest of Northeast Ohio, Pennsylvania, and through brief sections near Buffalo, Albany, and Boston. Erie, Pennsylvania, Madison, Wisconsin, Billings, Montana, the western I-90 terminus is in the SoDo neighborhood of Seattle. I-90 eastbound begins at exit 2B, Edgar Martínez Drive S and 4th Avenue S. I-90 westbound exit 2B ends at Edgar Martínez Dr and 4th Ave near Safeco Field, as well as 4th Ave just north of S. Royal Brougham Way near CenturyLink Field, about a block east of the entrance to the Port of Seattles container shipping terminal 46, the tunnel that carries I-90 under the Mount Baker Ridge is on the National Register of Historic Places. The east portal of the tunnel is constructed as a bas relief concrete sculpture and they are the second and fifth longest such bridges, respectively. Forty miles east of Bellevue, I-90 traverses the Cascade Ranges Snoqualmie Pass and it intersects I-82 shortly after exiting the mountains and crosses the Columbia River on the Vantage Bridge at mile post 137. After entering Spokane near mile post 279, it enters Idaho eighteen miles later, since 1980, I-90 from Seattle to Thorp was designated the Mountains to Sound Greenway to protect its outstanding scenic and cultural resources. The Washington section of I-90 is defined in the Revised Code of Washington, the small town of Wallace still prides itself on having what was the last stop light in the Rocky Mountains on I-90. As a result, the government was forced, at great expense, to reroute the freeway to the northern edge of downtown. That section of I-90 opened in September 1991, a bicycle path is routed beneath part of that segment. In the period between 1995 and 1999, there was no numbered speed limit on I-90 in Montana, the speed limit was simply defined as reasonable and prudent as determined on a case-by-case basis by the Montana Highway Patrol. The speed limit in Montana is now 80 mph, from the west I-90 enters Montana on the summit of Lookout Pass. It passes between the Gallatin and Bridger mountain ranges over Bozeman Pass between Bozeman and Livingston and it follows the Yellowstone River from Livingston to Billings where it connects the suburbs of Laurel and Lockwood with the rest of the Billings area. In Lockwood it intersects with I-94s western terminus and turns south, South of Hardin it passes the site of the Battle of the Little Bighorn at Crow Agency on the Crow Indian Reservation. Montana boasts the longest stretch of I-90, ranging just over 551 miles, I-90 enters the state of Wyoming from the north after splitting off from I-94 in Billings, Montana. The first major town is Sheridan where it heads southbound and it then goes across the Powder River Basin toward Gillette, Moorcroft, and Sundance where it shares alignments with both US14 and US16
