Mica Mountain (British Columbia)
Mica Mountain is a 2,855-meter-elevation (9,367-foot) mountain summit located in British Columbia, Canada. Description Mica Mountain is situated 12 kilometers (7.5 miles) southwest of Tête Jaune Cache, British Columbia, at the eastern edge of the Premier Range which is a subset of the Cariboo Mountains. The British Columbia Highway 5, Southern Yellowhead Highway passes the eastern base of the mountain as it traverses Robson Valley. Precipitation Surface runoff, runoff from Mica Mountain drains into Tête Creek and the McLennan River. Topographic relief is significant as the summit rises over 1,650 meters (5,400 feet) above the creek in four kilometers (2.5 miles). In good weather the view from the summit includes Mount Robson, Canoe Mountain (British Columbia), Canoe Mountain and Kinbasket Lake. The mountain's well-established local name was officially adopted 23 May 1962 by the Geographical Names Board of Canada. The name refers to the mineral mica which was mined from the higher ...

Mica
Micas ( ) are a group of silicate minerals whose outstanding physical characteristic is that individual mica crystals can easily be split into extremely thin elastic plates. This characteristic is described as perfect basal cleavage. Mica is common in igneous and metamorphic rock and is occasionally found as small flakes in sedimentary rock. It is particularly prominent in many granites, pegmatites, and schists, and "books" (large individual crystals) of mica several feet across have been found in some pegmatites. Micas are used in products such as drywalls, paints, fillers, especially in parts for automobiles, roofing and shingles, as well as in electronics. The mineral is used in cosmetics and food to add "shimmer" or "frost." Properties and structure The mica group is composed of 37 phyllosilicate minerals. All crystallize in the monoclinic system, with a tendency towards pseudohexagonal crystals, and are similar in structure but vary in chemical composition. Micas are ...

McLennan River
The McLennan River is a tributary of the Fraser River in the Robson Valley region of British Columbia. The river was named after an engineer on one of the Canadian Pacific Railway surveys in the 1870s. Course The McLennan River originates in the Premier Range, flowing from McLennan Glacier between Mount Stanley Baldwin and Mount Arthur Meighen. The river flows east out of the mountains into the Rocky Mountain Trench near Valemount. Then it turns northwest, flowing through the Rocky Mountain Trench, picking up tributary streams flowing from the Selwyn Range to the east and the Premier Range to the west. It joins the Fraser River at Tête Jaune Cache. See also *List of British Columbia rivers The following is a partial list of rivers of British Columbia, organized by watershed. Some large creeks are included either because of size or historical importance (See Alphabetical List of British Columbia rivers ). Also included are lakes th ... References Rivers of British C ...

Geography Of British Columbia
British Columbia is the westernmost province of Canada, bordered by the Pacific Ocean. With an area of it is Canada's third-largest province. The province is almost four times the size of the United Kingdom and larger than every United States state except Alaska. It is bounded on the northwest by the U.S. state of Alaska, directly north by Yukon and the Northwest Territories, on the east by Alberta, and on the south by the U.S. states of Washington, Idaho, and Montana. Formerly part of the British Empire, the southern border of British Columbia was established by the 1846 Oregon Treaty. The province is dominated by mountain ranges, among them the Canadian Rockies but dominantly the Coast Mountains, Cassiar Mountains, and the Columbia Mountains. Most of the population is concentrated on the Pacific coast, notably in the area of Vancouver, located on the southwestern tip of the mainland, which is known as the Lower Mainland. It is the most mountainous province of Canada. Statist ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Subarctic Climate
The subarctic climate (also called subpolar climate, or boreal climate) is a climate with long, cold (often very cold) winters, and short, warm to cool summers. It is found on large landmasses, often away from the moderating effects of an ocean, generally at latitudes from 50° to 70°N, poleward of the humid continental climates. Subarctic or boreal climates are the source regions for the cold air that affects temperate latitudes to the south in winter. These climates represent Köppen climate classification ''Dfc'', ''Dwc'', ''Dsc'', ''Dfd'', ''Dwd'' and ''Dsd''. Description This type of climate offers some of the most extreme seasonal temperature variations found on the planet: in winter, temperatures can drop to below and in summer, the temperature may exceed . However, the summers are short; no more than three months of the year (but at least one month) must have a 24-hour average temperature of at least to fall into this category of climate, and the coldest month should ave ...

Köppen Climate Classification
The Köppen climate classification is one of the most widely used climate classification systems. It was first published by German-Russian climatologist Wladimir Köppen (1846–1940) in 1884, with several later modifications by Köppen, notably in 1918 and 1936. Later, the climatologist Rudolf Geiger (1894–1981) introduced some changes to the classification system, which is thus sometimes called the Köppen–Geiger climate classification system. The Köppen climate classification divides climates into five main climate groups, with each group being divided based on seasonal precipitation and temperature patterns. The five main groups are ''A'' (tropical), ''B'' (arid), ''C'' (temperate), ''D'' (continental), and ''E'' (polar). Each group and subgroup is represented by a letter. All climates are assigned a main group (the first letter). All climates except for those in the ''E'' group are assigned a seasonal precipitation subgroup (the second letter). For example, ''Af'' indi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Kinbasket Lake
Kinbasket Lake (or Kinbasket Reservoir) is a reservoir on the Columbia River in southeast British Columbia, north of the city of Revelstoke and the town of Golden. The reservoir was created by the construction of the Mica Dam. The lake includes two reaches, Columbia Reach (to the south) and Canoe Reach (to the north), referring to the river valleys flooded by the dam. To the north it almost reaches the town of Valemount in an impoundment of the Canoe River. To the south it reaches upstream the Columbia River towards the city of Golden. The original, smaller Kinbasket Lake was named in 1866 after Kinbasket, a chief of the Shuswap people. The modern, large lake was created after the completion of the Mica Dam in 1973, and was called McNaughton Lake (after Andrew McNaughton) until 1980. A number of small communities were inundated by the creation of Kinbasket Lake, and comprised a region known as the Big Bend Country, a subregion of the Columbia Country. Among these towns were Mi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Canoe Mountain (British Columbia)
Canoe Mountain is a 2,651-meter-elevation (8,698-foot) mountain summit located in British Columbia, Canada. Description Canoe Mountain is situated 16 kilometers (10 miles) south-southeast of the community of Valemount, at the northern end of the Malton Range which is a subset of the Monashee Mountains. The British Columbia Highway 5, Southern Yellowhead Highway traverses the western base of the mountain. Precipitation Surface runoff, runoff from Canoe Mountain drains west into Camp Creek which is tributary of the Canoe River (British Columbia), Canoe River, as well as east into Kinbasket Lake. Topographic relief is significant as the summit rises 1,920 meters (6,300 feet) above the lake in five kilometers (3 miles). The steep north aspect of the mountain holds a cirque, whereas an unpaved fire service road climbs the modest west slope to a telecommunications tower at the top. The mountain's long-established local name was officially adopted 16 November 1976 by the Geographical Name ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mount Robson
Mount Robson is the most prominent mountain in North America's Rocky Mountain range; it is also the highest point in the Canadian Rockies. The mountain is located entirely within Mount Robson Provincial Park of British Columbia, and is part of the Rainbow Range. Mount Robson is the second highest peak entirely in British Columbia, behind Mount Waddington in the Coast Range. The south face of Mount Robson is clearly visible from the Yellowhead Highway (Highway 16), and is commonly photographed along this route. Mount Robson was likely named after Colin Robertson, who worked for both the North West Company and the Hudson's Bay Company at various times in the early 19th century, though there was confusion over the name as many assumed it to have been named for John Robson, an early premier of British Columbia. The Texqakallt, a Secwepemc people and the earliest known inhabitants of the area, call it (striped rock), spelled in Dawson 1891 as , ''The Mountain of the Spiral ...

Topographic Relief
Terrain or relief (also topographical relief) involves the vertical and horizontal dimensions of land surface. The term bathymetry is used to describe underwater relief, while hypsometry studies terrain relative to sea level. The Latin word (the root of ''terrain'') means "earth." In physical geography, terrain is the lay of the land. This is usually expressed in terms of the elevation, slope, and orientation of terrain features. Terrain affects surface water flow and distribution. Over a large area, it can affect weather and climate patterns. Importance The understanding of terrain is critical for many reasons: * The terrain of a region largely determines its suitability for human settlement: flatter alluvial plains tend to have better farming soils than steeper, rockier uplands. * In terms of environmental quality, agriculture, hydrology and other interdisciplinary sciences; understanding the terrain of an area assists the understanding of watershed boundaries, drai ...

Surface Runoff
Surface runoff (also known as overland flow) is the flow of water occurring on the ground surface when excess rainwater, stormwater, meltwater, or other sources, can no longer sufficiently rapidly infiltrate in the soil. This can occur when the soil is saturated by water to its full capacity, and the rain arrives more quickly than the soil can absorb it. Surface runoff often occurs because impervious areas (such as roofs and pavement) do not allow water to soak into the ground. Furthermore, runoff can occur either through natural or man-made processes. Surface runoff is a major component of the water cycle. It is the primary agent of soil erosion by water. The land area producing runoff that drains to a common point is called a drainage basin. Runoff that occurs on the ground surface before reaching a channel can be a nonpoint source of pollution, as it can carry man-made contaminants or natural forms of pollution (such as rotting leaves). Man-made contaminants in runoff i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
