Canada
Canada is a country in North America. Its ten provinces and three territories extend from the Atlantic Ocean to the Pacific Ocean and northward into the Arctic Ocean, covering over , making it the world's second-largest country by total area. Its southern and western border with the United States, stretching , is the world's longest binational land border. Canada's capital is Ottawa, and its three largest metropolitan areas are Toronto, Montreal, and Vancouver. Indigenous peoples have continuously inhabited what is now Canada for thousands of years. Beginning in the 16th century, British and French expeditions explored and later settled along the Atlantic coast. As a consequence of various armed conflicts, France ceded nearly all of its colonies in North America in 1763. In 1867, with the union of three British North American colonies through Confederation, Canada was formed as a federal dominion of four provinces. This began an accretion of provinces an ...

Whitehorse
Whitehorse () is the capital of Yukon, and the largest city in Northern Canada. It was incorporated in 1950 and is located at kilometre 1426 (Historic Mile 918) on the Alaska Highway in southern Yukon. Whitehorse's downtown and Riverdale areas occupy both shores of the Yukon River, which rises in British Columbia and meets the Bering Sea in Alaska. The city was named after the White Horse Rapids for their resemblance to the mane of a white horse, near Miles Canyon, before the river was dammed. Because of the city's location in the Whitehorse valley and relative proximity to the Pacific Ocean, the climate is milder than comparable northern communities such as Yellowknife. At this latitude, winter days are short and summer days have up to about 19 hours of daylight. Whitehorse, as reported by ''Guinness World Records'', is the city with the least air pollution in the world. As of the 2021 Canadian census, the population was 28,201 within city boundaries and 31,913 in the census ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Indian Reserve
In Canada, an Indian reserve (french: réserve indienne) is specified by the '' Indian Act'' as a "tract of land, the legal title to which is vested in Her Majesty, that has been set apart by Her Majesty for the use and benefit of a band." Indian reserves are the areas set aside for First Nations, an indigenous Canadian group, after a contract with the Canadian state ("the Crown"), and are not to be confused with land claims areas, which involve all of that First Nations' traditional lands: a much larger territory than any reserve. Demographics A single "band" (First Nations government) may control one reserve or several, while other reserves are shared between multiple bands. In 2003, the Department of Indian and Northern Affairs stated there were 2,300 reserves in Canada, comprising . According to Statistics Canada in 2011, there are more than 600 First Nations/Indian bands in Canada and 3,100 Indian reserves across Canada. Examples include the Driftpile First Nation, wh ...

Escarpment
An escarpment is a steep slope or long cliff that forms as a result of faulting or erosion and separates two relatively level areas having different elevations. The terms ''scarp'' and ''scarp face'' are often used interchangeably with ''escarpment''. Some sources differentiate the two terms, with ''escarpment'' referring to the margin between two landforms, and ''scarp'' referring to a cliff or a steep slope. In this usage an escarpment is a ridge which has a gentle slope on one side and a steep scarp on the other side. More loosely, the term ''scarp'' also describes a zone between a coastal lowland and a continental plateau which shows a marked, abrupt change in elevation caused by coastal erosion at the base of the plateau. Formation and description Scarps are generally formed by one of two processes: either by differential erosion of sedimentary rocks, or by movement of the Earth's crust at a geologic fault. The first process is the more common type: the escarpment is a t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lava Plateau
A volcanic plateau is a plateau produced by volcanism, volcanic activity. There are two main types: lava plateaus and pyroclastic plateaus. Lava plateau Lava plateaus are formed by highly fluid basaltic lava during numerous successive eruptions through numerous vents without violent explosions (quiet eruptions). These eruptions are quiet because of low viscosity of lava, so that it is very fluid and contains a small amount of trapped gases. The resulting sheet lava flows may be extruded from linear fissure vent, fissures or rifts or gigantic volcanic eruptions through multiple vents characteristic of the prehistoric era which produced giant flood basalts. Multiple successive and extensive lava flows cover the original landscape to eventually form a plateau, which may contain lava fields, cinder cones, shield volcanoes and other :Volcanic landforms, volcanic landforms. In some cases, a lava plateau may be part of a single volcano. An example is the massive Level Mountain shi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Meszah Peak
Meszah Peak is a volcanic cone located north of Telegraph Creek and southwest of Zus Mountain in British Columbia, Canada. It is the highest peak of the Level Mountain Range, a cluster of bare peaks on the summit of the massive Level Mountain shield volcano, which forms the most voluminous and most persistent eruptive centre in the Northern Cordilleran Volcanic Province.

Shield Volcano
A shield volcano is a type of volcano named for its low profile, resembling a warrior's shield lying on the ground. It is formed by the eruption of highly fluid (low viscosity) lava, which travels farther and forms thinner flows than the more viscous lava erupted from a stratovolcano. Repeated eruptions result in the steady accumulation of broad sheets of lava, building up the shield volcano's distinctive form. Shield volcanoes are found wherever fluid low-silica lava reaches the surface of a rocky planet. However, they are most characteristic of ocean island volcanism associated with hot spots or with continental rift volcanism. They include the largest volcanoes on earth, such as Tamu Massif and Mauna Loa. Giant shield volcanoes are found on other planets of the Solar System, including Olympus Mons on Mars and Sapas Mons on Venus. Etymology The term 'shield volcano' is taken from the German term ''Schildvulkan'', coined by the Austrian geologist Eduard Suess in 1888 an ...

Tahltan
The Tahltan or Nahani are a First Nations people of the Athabaskan-speaking ethnolinguistic group who live in northern British Columbia around Telegraph Creek, Dease Lake, and Iskut. The Tahltan constitute the fourth division of the ''Nahane'' (People of the West). Culture The Tahltan cultural practices and lifeways varied widely as they were often widely separated and would have to endure varying conditions depending on their locality. In Tahltan culture it was believed that some of their ancestors had knowledge that others did not from times before a great flood. Some of these ancestors used that knowledge for the good of the people, while others used it for evil and to the disadvantage of others. Raven is considered to be the protagonist hero against these evil ancestors. Social organization Tahltan social organization is founded on matriarchy and intermarriage between two main clan designations. The two main clans of Tahltan people are Tses' Kiya (pronounced Tses-kee-ya ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Barren Vegetation
Barren vegetation describes an area of land where plant growth may be sparse, stunted, and/or contain limited biodiversity. Environmental conditions such as toxic or infertile soil, high winds, coastal salt-spray, and climatic conditions are often key factors in poor plant growth and development. Barren vegetation can be categorized depending on the climate, geology, and geographic location of a specific area. Pine barrens, coastal barrens, and serpentine barrens Serpentine soil is an uncommon soil type produced by weathered ultramafic rock such as peridotite and its metamorphic derivatives such as serpentinite. More precisely, serpentine soil contains minerals of the serpentine subgroup, especially anti ... are some of the more distinct ecoregions for barren vegetation and are the most commonly researched by scientists. Often referred to as "heathlands", barrens can be excellent environments for unique biological diversity and taxonomic compositions. Serpentine Barrens Bi ...

Mixed Coniferous Forest
Mixed coniferous forest is a vegetation type dominated by a mixture of broadleaf trees and conifers.Sierra Nevada Wildflowers, Karen Wiese, 2nd ed, 2013, p 13–14 It is generally located in mountains, below the upper montane vegetation type. Sierra Nevada range In the Sierra Nevada mountain range of the western United States, the mixed coniferous forest is found at elevations of in the north, in central areas, and in the south. Characteristic conifers include Ponderosa Pine ('' Pinus ponderosa''), Sugar Pine (''Pinus lambertiana''), Incense Cedar (''Calocedrus decurrens''), White Fir (''Abies concolor''), Douglas Fir (''Pseudotsuga menziesii''), and Giant Sequoias (''Sequoiadendron giganteum'') in pockets. Characteristic broadleaved trees include Black Oak (''Quercus kelloggii''), and understory trees and shrubs, including Canyon Live Oak (''Quercus chrysolepis''), Dogwood ( ''Cornus'' spp.), Mountain Misery (''Chamaebatia foliolosa''), and Manzanitas ( ''Arctostaphylos'' spp ...

Herbaceous Plant
Herbaceous plants are vascular plants that have no persistent woody stems above ground. This broad category of plants includes many perennials, and nearly all annuals and biennials. Definitions of "herb" and "herbaceous" The fourth edition of the ''Shorter Oxford English Dictionary'' defines "herb" as: #"A plant whose stem does not become woody and persistent (as in a tree or shrub) but remains soft and succulent, and dies (completely or down to the root) after flowering"; #"A (freq. aromatic) plant used for flavouring or scent, in medicine, etc.". (See: Herb) The same dictionary defines "herbaceous" as: #"Of the nature of a herb; esp. not forming a woody stem but dying down to the root each year"; #"BOTANY Resembling a leaf in colour or texture. Opp. scarious". Botanical sources differ from each other on the definition of "herb". For instance, the Hunt Institute for Botanical Documentation includes the condition "when persisting over more than one growing season, the parts o ...
