Kootenay Lake
Kootenay Lake is a lake located in British Columbia, Canada. It 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. The Kootenay Lake ferry is a year-round toll-free ferry that crosses between Kootenay Bay and Balfour. The lake is a popular summer tourist destination. Geography Kootenay Lake is a long, narrow and deep fjord-like lake located between the Selkirk and Purcell mountain ranges in the Kootenay region of British Columbia. It is one of the largest lakes in British Columbia, at 104 km in length and 3–5 km in width. It is, in part, a widening of the Kootenay River, which in turn drains into the Columbia River system at Castlegar, British Columbia. Although oriented primarily in a north-south configuration, a western arm positioned roughly halfway up the length of the lake stretches 35&nb ...

Corra Linn Dam
Corra Linn Dam is a concrete hydroelectric dam on the Kootenay River between the cities of Castlegar and Nelson, in the West Kootenay region of southern British Columbia. Rapids The Corra Linn Rapids, named after the Falls of Clyde upper falls of Cora Linn, preceded the dam at this location. Neighbourhood The adjacent former train station and neighbourhood were named after the rapids, but the locality has been frequently misspelled as Corra Lynn. Dam For the six-year period after the 1932 opening, the dam was not permitted to raise the level of Kootenay Lake. It operated as a run-of-the-river hydroelectricity plant allowing the spring freshet to pass downstream. After devastating floods to Idaho farmlands in 1938, the International Joint Commission granted two approvals. The first allowed excavation to the outlet of the lake at Grohman Narrows. In 1939, of gravel and of rock were removed, which included rock bluffs on the south side of the river. The narrows was made deeper ...

Virtual Museum Of Canada
The Digital Museums Canada (DMC; , ''MNC'') is a funding program in Canada "dedicated to online projects by the museum and heritage community," helping organizations to build digital capacity. Administered by the Canadian Museum of History (CMH) with the financial support of the Government of Canada, DMC provides investments of CA$15,000 to $250,000 for audience-engaging online projects by Canadian museums and heritage organizations. As of 2021, Digital Museums Canada took the place of the Virtual Museum of Canada (VMC), a national virtual museum. With a directory of over 3,000 Canadian heritage institutions and a database of over 600 virtual exhibits, VMC's site was scheduled to discontinue hosting exhibits after 30 June 2021. Virtual Museum of Canada Virtual Museum of Canada (VMC) was a national virtual museum that was replaced by Digital Museums Canada as of 2021. VMC was administered by the Canadian Museum of History (CMH), and its content was created by Canadian museums. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Castlegar, British Columbia
Castlegar is the second-largest community in the West Kootenay region of British Columbia, Canada. In the Selkirk Mountains, at the confluence of the Kootenay and Columbia Rivers, it is a regional trade and transportation centre, with a local economy based on forestry, mining and tourism. Castlegar was recently cited as one of the Top Eight Places in British Columbia for most promising growth. It is home to Selkirk College, a regional airport, a pulp mill, and several sawmills. Its population of 7,259 includes many Doukhobors, who were largely responsible for much of the town's early development and growth. The area which became Castlegar was an important centre for the Sinixt (Lakes) Peoples. Outside the city limits are the small surrounding communities of Ootischenia, Brilliant, Robson, Robson West, Raspberry, Tarrys, Thrums, Glade, Shoreacres, Fairview, Genelle, Pass Creek and Krestova, and the much smaller communities of Deer Park, Renata, and Syringa on Lower Arrow Lake ...

Electric Power Transmission
Electric power transmission is the bulk movement of electrical energy from a generating site, such as a power plant, to an electrical substation. The interconnected lines that facilitate this movement form a ''transmission network''. This is distinct from the local wiring between high-voltage substations and customers, which is typically referred to as electric power distribution. The combined transmission and distribution network is part of electricity delivery, known as the electrical grid. Efficient long-distance transmission of electric power requires high voltages. This reduces the losses produced by strong currents. Transmission lines use either alternating current (HVAC) or direct current (HVDC). The voltage level is changed with transformers. The voltage is stepped up for transmission, then reduced for local distribution. A wide area synchronous grid, known as an "interconnection" in North America, directly connects generators delivering AC power with the same rela ...

Kootenay Lake Crossing
Kootenay Lake Crossing is a powerline crossing of Kootenay Lake, British Columbia, Canada. The idea was to transport electricity from the Hydro dam on the Kootenay River at Brilliant to the Cominco Sullivan Mine at Kimberley. The most direct route was across Kootenay Lake. Originally it was with a span width of the longest powerline span of North America and fixed on three - for each conductor a single one - 19 metres tall towers at the west shore and a tall electricity pylon on the east shore. This tower was erected in spite of high mountains on the east shore for building short towers were available, as erecting span terminal towers on them would have required a longer span, for which the use of spliced conductors were required, which was undesired as the splicing point is a potential point of failure. Roebling cable provided the steel support cable for the conductor. The height of conductor over Kootenay Lake was . Kootenay Lake Crossing was inaugurated in 1952, but on March 8 ...

Ktunaxa
The Kutenai ( ), also known as the Ktunaxa ( ; ), Ksanka ( ), Kootenay (in Canada) and Kootenai (in the United States), are an indigenous people of Canada and the United States. Kutenai bands live in southeastern British Columbia, northern Idaho, and western Montana. The Kutenai language is a language isolate, thus unrelated to the languages of neighboring peoples or any other known language. Four bands form the Ktunaxa Nation in British Columbia. The Ktunaxa Nation was historically closely associated with the Shuswap Indian Band through tribal association and intermarriage. Two federally recognized tribes represent Kutenai people in the U.S.: the Kootenai Tribe of Idaho and the Confederated Salish and Kootenai Tribes in Montana, a confederation also including Bitterroot Salish and Pend d'Oreilles bands. Kootenay Around 40 variants of the name ''Kutenai'' have been attested since 1820; two others are also in current use. ''Kootenay'' is the common spelling in British Colu ...

Sinixt
The Sinixt"Sinixt Nation…" (also known as the Sin-Aikst or Sin Aikst,Reyes 2002, ''passim.'' "Senjextee", "Arrow Lakes Band", or — less commonly in recent decades — simply as "The Lakes") are a First Nations People. The Sinixt are descended from Indigenous peoples who have lived primarily in what are today known as the West Kootenay region of British Columbia in Canada and the adjacent regions of Eastern Washington in the United States for at least 10,000 years. The Sinixt are of Salishan linguistic extraction, and speak their own dialect ( sn-selxcin) of the Colville-Okanagan language. Today they live primarily on the Colville Indian Reservation in Washington, where they form part of the Confederated Tribes of the Colville Reservation, which is recognized by the United States government as an American Indian Tribe. Many Sinixt continue to live in their traditional territory on the Northern Side of the 49th Parallel, particularly in the Slocan Valley and scattered ...

Libby, Montana
Libby is a city in northwestern Montana, United States and the county seat of Lincoln County. The population was 2,775 at the 2020 census. Libby suffered from the area's contamination from nearby vermiculite mines contaminated with particularly fragile asbestos, leading to the town's inclusion in the United States Environmental Protection Agency's National Priorities List status in 2002 and Public Health Emergency event in 2009. Most risk was reduced by 2015. Local natural features such as the Kootenai Falls have attracted tourism to the area and have been featured in movies such as ''The River Wild'' (1994) and '' The Revenant'' (2015). There is a public school district and a public library, and the town is in-district for Flathead Valley Community College, which operates the Lincoln County Campus there. History Continental and alpine glaciers shaped the area's valleys and lakes. The first indigenous peoples arrived at least 8,000 years ago and hunted and gathered for food. ...

Moraine
A moraine is any accumulation of unconsolidated debris (regolith and rock), sometimes referred to as glacial till, that occurs in both currently and formerly glaciated regions, and that has been previously carried along by a glacier or ice sheet. It may consist of partly rounded particles ranging in size from boulders (in which case it is often referred to as boulder clay) down to gravel and sand, in a groundmass of finely-divided clayey material sometimes called glacial flour. Lateral moraines are those formed at the side of the ice flow, and terminal moraines were formed at the foot, marking the maximum advance of the glacier. Other types of moraine include ground moraines (till-covered areas forming sheets on flat or irregular topography) and medial moraines (moraines formed where two glaciers meet). Etymology The word ''moraine'' is borrowed from French , which in turn is derived from the Savoyard Italian ("mound of earth"). ''Morena'' in this case was derived from Provenà ...

Glaciers
A glacier (; ) is a persistent body of dense ice that is constantly moving under its own weight. A glacier forms where the accumulation of snow exceeds its ablation over many years, often centuries. It acquires distinguishing features, such as crevasses and seracs, as it slowly flows and deforms under stresses induced by its weight. As it moves, it abrades rock and debris from its substrate to create landforms such as cirques, moraines, or fjords. Although a glacier may flow into a body of water, it forms only on land and is distinct from the much thinner sea ice and lake ice that form on the surface of bodies of water. On Earth, 99% of glacial ice is contained within vast ice sheets (also known as "continental glaciers") in the polar regions, but glaciers may be found in mountain ranges on every continent other than the Australian mainland, including Oceania's high-latitude oceanic island countries such as New Zealand. Between latitudes 35°N and 35°S, glaciers occur only ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pleistocene
The Pleistocene ( , often referred to as the ''Ice age'') is the geological Epoch (geology), epoch that lasted from about 2,580,000 to 11,700 years ago, spanning the Earth's most recent period of repeated glaciations. Before a change was finally confirmed in 2009 by the International Union of Geological Sciences, the cutoff of the Pleistocene and the preceding Pliocene was regarded as being 1.806 million years Before Present (BP). Publications from earlier years may use either definition of the period. The end of the Pleistocene corresponds with the end of the last glacial period and also with the end of the Paleolithic age used in archaeology. The name is a combination of Ancient Greek grc, label=none, πλεῖστος, pleīstos, most and grc, label=none, καινός, kainós (latinized as ), 'new'. At the end of the preceding Pliocene, the previously isolated North and South American continents were joined by the Isthmus of Panama, causing Great American Interchang ...

Cretaceous
The Cretaceous ( ) is a geological period that lasted from about 145 to 66 million years ago (Mya). It is the third and final period of the Mesozoic Era, as well as the longest. At around 79 million years, it is the longest geological period of the entire Phanerozoic. The name is derived from the Latin ''creta'', "chalk", which is abundant in the latter half of the period. It is usually abbreviated K, for its German translation ''Kreide''. The Cretaceous was a period with a relatively warm climate, resulting in high eustatic sea levels that created numerous shallow inland seas. These oceans and seas were populated with now- extinct marine reptiles, ammonites, and rudists, while dinosaurs continued to dominate on land. The world was ice free, and forests extended to the poles. During this time, new groups of mammals and birds appeared. During the Early Cretaceous, flowering plants appeared and began to rapidly diversify, becoming the dominant group of plants across the Earth b ...
