The elk , or wapiti (" Cervus canadensis "), is one ___MASK15___ the largest species within the deer family , Cervidae , in the world , and one ___MASK15___ the largest land mammals in North America and Eastern Asia . This animal should not be confused with the still larger moose (" Alces alces ") to which the name " elk " applies in British English and in reference to populations in Eurasia . Apart from the moose , the only other member ___MASK15___ the deer family to rival the elk in size is the south Asian sambar (" Rusa unicolor "). Boat Encampment was a rendezvous and staging point for the ___MASK76___ ' s Bay Company in the early 19th century and later a locality by that name in the Canadian province of ___MASK78___ .

Its site today is beneath the waters of Kinbasket Lake Reservoir , formed by the Mica Dam of the Columbia River Treaty . " Main Stem " is 1942 instrumental by Duke ___MASK35___ and His Famous Orchestra . Although recorded in 1942 , the single would not be released until 1944 where it was Duke ___MASK35___ ' s last ___MASK15___ four number one ' s on the Harlem Hit Parade . " Main Stem " also peaked at number twenty on the pop chart . The Goldstream ___MASK62___ is a tributary ___MASK15___ the ___MASK94___ ___MASK62___ , joining that stream via the Lake Revelstoke reservoir after running largely west from the heart ___MASK15___ the northern Selkirk Mountains .

The ___MASK75___ River is a long river in the Canadian province of ___MASK78___ . Its drainage basin is in area . It is part of the Columbia River basin , being tributary via Kootenay Lake to the Kootenay River , which is a tributary of the Columbia River . It forms part of the boundary between the Selkirk Mountains , to its west , and the Purcell Mountains , to its east ( the boundary northwards is the Beaver River ). The Kootenay ( Kootenai in the U . S . and historically called the Flatbow ) is a major ___MASK62___ in southeastern ___MASK78___ , Canada and northern parts of the U . S . states of Montana and Idaho .

The Kootenay River runs from its headwaters in the Kootenay Ranges of the Canadian Rockies , flowing from ___MASK78___ ' s East Kootenay region into northwestern Montana , thence into northernmost Idaho Panhandle and returning to ___MASK78___ in the West Kootenay region , where it joins the Columbia at Castlegar . ___MASK78___ ( BC ) is the westernmost province of Canada , with a population of more than four million people located between the Pacific Ocean and the Rocky Mountains . ___MASK78___ 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 Pacific ___MASK24___ ( in the United States , commonly abbreviated as PNW ), sometimes referred to as Cascadia , is a geographic region in western North America bounded by the Pacific Ocean to the west and loosely , by the Rocky Mountains on the east . Though no agreed boundary exists , a common conception includes the U . S . states of Oregon and Washington and the Canadian province of ___MASK78___ . Broader conceptions reach north into Alaska and Yukon , south into far northern California and east to the Continental Divide , thus including Idaho , Western Montana , and western Wyoming . Narrower conceptions may be limited to the northwestern US or to the coastal areas west of the Cascade and Coast mountains . The variety of definitions can be attributed to partially overlapping commonalities of the region ' s history , geography , society , and other factors . A lake is an area ___MASK15___ variable size filled with water , localized in a basin , that is surrounded by land , apart from any river or other outlet that serves to feed or drain the lake . ___MASK27___ lie on land and are not part ___MASK15___ the ocean , and therefore are distinct from lagoons , and are also larger and deeper than ponds , though there are no official or scientific definitions . ___MASK27___ can be contrasted with rivers or streams , which are usually flowing . Most ___MASK27___ are fed and drained by rivers and streams . The International ___MASK79___ Loop is a scenic highway in the U . S . states of Idaho and Washington , as well as the Canadian province of ___MASK78___ . The loop encircles the ___MASK79___ Mountain Range , and offers several side trips aside from the main route .

The portion of the loop in the United States has been designated an All - American Road by the United States Department of Transportation . The Arrow ___MASK27___ in ___MASK78___ , Canada , divided into Upper Arrow Lake and Lower Arrow Lake , are widenings of the Columbia River . The lakes are situated between the Selkirk Mountains to the east and the Monashee Mountains to the west . Beachland is fairly rare , and is interspersed with rocky headlands and steep cliffs . Mountain sides are heavily forested , and rise sharply to elevations around 2 , 600 metres . Originally two lakes 14 miles apart , the Arrow ___MASK27___ became one 230 km long lake due to the reservoir created by the 1960s construction of the Keenleyside Dam ; at low water the two lakes remain distinct , connected by a fast - moving section known as the Narrows . Damming the Lower Arrow Lake resulted in water rising 12 metres above natural levels . As a result of higher water , the valley lost 2 / 3 of its arable land . Thousands of people relocated . The lake stretches from just north of Castlegar in the south to Revelstoke in the north . Another hydroelectric development Whatshan Dam , diverted Whatshan Lake from the Whatshan River directly into the Arrow ___MASK27___ , just north of the Needles - Fauquier Ferry . Kootenay Lake is a lake located in ___MASK78___ , Canada and is part of the Kootenay River . The lake has been raised by the Corra Linn Dam and has a dike system at the southern end , which , along with industry in the 1950s - 70s , has changed the ecosystem in and around the water . Kootenay Lake has a year - round toll - free ferry that crosses between Kootenay Bay and Balfour , and is a popular summer tourist destination .

A tributary or affluent is a stream or ___MASK62___ that flows into a larger stream or main stem ( or parent ) ___MASK62___ or a lake . A tributary does not flow directly into a sea or ocean . Tributaries and the main stem ___MASK62___ drain the surrounding drainage ___MASK63___ ___MASK15___ its surface water and groundwater , leading the water out into an ocean . The Cariboo Mountains are the northernmost subrange ___MASK15___ the ___MASK94___ Mountains , which run down into the ___MASK39___ , Washington area ___MASK15___ the United States and include the Selkirks , Monashees and Purcells . The Cariboo Mountains are entirely within the province ___MASK15___ ___MASK78___ , Canada . The range is 7 , 700 km² ( c . 2 , 975 sq mi ) in area and about 245 km in length ( SE - NW ) and about 90 km at its widest ( SW - NE ). Northport is a town in ___MASK13___ , ___MASK2___ , United States . The population was 295 at the 2010 census . A ___MASK62___ is a natural flowing watercourse , usually ___MASK83___ , flowing towards an ocean , sea , lake or another ___MASK62___ . In some cases a ___MASK62___ flows into the ground and becomes dry at the end of its course without reaching another body of water . Small rivers can be referred to using names such as stream , creek , brook , rivulet , and rill . There are no official definitions for the generic term ___MASK62___ as applied to geographic features , although in some countries or communities a stream is defined by its size . Many names for small rivers are specific to geographic location ; examples are " run " in some parts of the United States , " burn " in Scotland and northeast England , and " beck " in northern England . Sometimes a ___MASK62___ is defined as being larger than a creek , but not always : the language is vague . A drainage ___MASK63___ or catchment ___MASK63___ is an extent or an area ___MASK15___ land where all surface water from rain , melting snow , or ice converges to a single point at a lower elevation , usually the exit ___MASK15___ the ___MASK63___ , where the waters join another body ___MASK15___ water , such as a river , lake , reservoir , estuary , wetland , sea , or ocean . Thus if a tributary stream joins a brook that in turn joins a small river which is a tributary ___MASK15___ a larger river , there is a series ___MASK15___ successively larger ( and lower elevation ) drainage basins . For instance , the ___MASK72___ and Ohio rivers are within their own drainage basins and also within the drainage ___MASK63___ ___MASK15___ the Mississippi River . The ___MASK94___ Mountains are a group of mountain ranges along the upper ___MASK94___ River in southeastern ___MASK78___ , and also in Montana , Idaho and Washington . The mountain range covers 135 , 952 km² ( 52 , 491 sq mi ). The range is bounded by the Rocky Mountain Trench on the east , and the Kootenay River on the south ; their western boundary is the edge of the Interior Plateau . Seventy - five percent of the range is located in Canada and the remaining twenty - five percent in the United States ; American geographic classifications place the ___MASK94___ Mountains as part of the Rocky Mountains complex , but this designation does not apply in Canada ( despite a ___MASK78___ government tourism campaign to rebrand their southern portion as the " Kootenay Rockies "). Mount Sir Sandford is the highest mountain in the range , reaching . The Purcell Mountains are a ___MASK53___ range in southeastern ___MASK78___ , ___MASK60___ . They are a subrange of the Columbia Mountains , which includes the Selkirk , Monashee , and Cariboo Mountains . They are located on the west side of the Rocky Mountain Trench in the area of the Columbia Valley , and on the east side of the valley of Kootenay Lake and the Duncan River . The only large settlement in the mountains is the Panorama Ski Resort , though there are small settlements , such as Yahk and Moyie along the Crowsnest Highway , and residential rural areas dependent on the cities of Creston , ___MASK71___ and Cranbrook , which are located adjacent to the range .

Major gold rushes took place in the 19th century in ___MASK85___ , New Zealand , ___MASK95___ , Canada , South Africa and the United States , while smaller gold rushes took place elsewhere . Kinbasket Lake ( or Kinbasket Reservoir ) is a reservoir on the ___MASK94___ River in southeast ___MASK78___ , ___MASK97___ ___MASK15___ the city ___MASK15___ Revelstoke and the town ___MASK15___ Golden . The reservoir was created by the construction ___MASK15___ the Mica Dam . The lake includes two reaches , ___MASK94___ Reach ( to the south ) and Canoe Reach ( to the ___MASK97___ ), referring to the river valleys flooded by the dam . To the ___MASK97___ it almost reaches the town ___MASK15___ Valemount in an impoundment ___MASK15___ the Canoe River . To the south it reaches upstream the ___MASK94___ River towards the city ___MASK15___ Golden . A stream is a body ___MASK15___ water with a current , confined within a bed and ___MASK100___ .
