Lava Canyon
Lava Canyon is a canyon on the Chilko River in the Chilcotin District of the Interior of British Columbia, Canada, located about 35 kilometres below the Chilko's outflow from the foot of Chilko Lake. Lava Canyon is named for the columnar basalt cliffs that form the canyon from former extensive volcanic activity of this region.

Canyon
A canyon (from ; archaic British English spelling: ''cañon''), or gorge, is a deep cleft between escarpments or cliffs resulting from weathering and the erosion, erosive activity of a river over geologic time scales. Rivers have a natural tendency to cut through underlying surfaces, eventually wearing away rock layers as sediments are removed downstream. A river bed will gradually reach a baseline elevation, which is the same elevation as the body of water into which the river drains. The processes of weathering and erosion will form canyons when the river's River source, headwaters and estuary are at significantly different elevations, particularly through regions where softer rock layers are intermingled with harder layers more resistant to weathering. A canyon may also refer to a rift between two mountain peaks, such as those in ranges including the Rocky Mountains, the Alps, the Himalayas or the Andes. Usually, a river or stream carves out such splits between mountains. Examp ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Chilko River
The Chilko River is a river in the Chilcotin District of the Central Interior of British Columbia, Canada, flowing northeast from Chilko Lake to the Chilcotin River. Its main tributary is the Taseko River. The Chilko is the Chilcotin River's main tributary. In fact at their confluence the Chilko River is much larger than the Chilcotin. It is also the main reason why the lower reaches of the Chilcotin are very silty. The Chilko gets most of its silt from the Taseko River, which joins it a few kilometers above the Chilko's mouth. Name origin The name "Chilko" is the product of linguistic anglicisation of the Tŝilhqot’in name ''Tŝilhqóx'', (also spelled without vowel flattening as ''Tsilhqox''). The meaning of the name is contested, and is the subject of much folk etymologising. Some believe the meaning to be "ochre river", but other contenders are "axe river" (from ''tŝinlh yeqox''), "river from the ponderosa pine" (from ''tsilhtsilh yeqox''), or "river with rocks" (from ' ...

Chilcotin District
The Chilcotin () region of British Columbia is usually known simply as "the Chilcotin", and also in speech commonly as "the Chilcotin Country" or simply Chilcotin. It is a plateau and mountain region in British Columbia on the inland lee of the Coast Mountains on the west side of the Fraser River. Chilcotin is also the name of the river draining that region. In the language of the Chilcotin people their name and the name of the river means "people of the red ochre river" (its tributary the Chilko River means "red ochre river") The Chilcotin district is often viewed as an extension of the Cariboo region, east of that river, although it has a distinct identity from the Cariboo District. It is, nonetheless, part of the Cariboo Regional District which is a municipal-level body governing some aspects of infrastructure and land-used planning. The vast majority of the population are First Nations people, members of the Tsilhqot'in and Dakelh peoples, while others are settlers and ran ...

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 ...

Columnar Basalt
Basalt (; ) is an aphanitic (fine-grained) extrusive igneous rock formed from the rapid cooling of low-viscosity lava rich in magnesium and iron (mafic lava) exposed at or very near the surface of a rocky planet or moon. More than 90% of all volcanic rock on Earth is basalt. Rapid-cooling, fine-grained basalt is chemically equivalent to slow-cooling, coarse-grained gabbro. The eruption of basalt lava is observed by geologists at about 20 volcanoes per year. Basalt is also an important rock type on other planetary bodies in the Solar System. For example, the bulk of the plains of Venus, which cover ~80% of the surface, are basaltic; the lunar maria are plains of flood-basaltic lava flows; and basalt is a common rock on the surface of Mars. Molten basalt lava has a low viscosity due to its relatively low silica content (between 45% and 52%), resulting in rapidly moving lava flows that can spread over great areas before cooling and solidifying. Flood basalts are thick sequence ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Anahim Volcanic Belt
The Anahim Volcanic Belt (AVB) is a west–east trending chain of volcanoes and related magmatic features in British Columbia, Canada. It extends from Athlone Island on the Central Coast, running eastward through the strongly uplifted and deeply dissected Coast Mountains to near the community of Nazko on the Interior Plateau. The AVB is delineated as three west-to-east segments that differ in age and structure. A wide variety of igneous rocks with differing compositions occur throughout these segments, comprising landforms such as volcanic cones, volcanic plugs, lava domes, shield volcanoes and intrusions. Volcanic activity has occurred repeatedly in the AVB for the last 15 million years, during which time three major magmatic episodes took place 15–13, 9–6 and 3–1 million years ago. These major magmatic episodes are represented by plutons, dike swarms, volcanic fields and large shield volcanoes. Volcanic activity in the last 1 million years has been relatively minor an ...

Chilcotin Group
The Chilcotin Group, also called the Chilcotin Plateau Basalts, is a large area of basaltic lava that forms a volcanic plateau running parallel with the Garibaldi Volcanic Belt in south-central British Columbia, Canada. Predominantly, during Miocene and Pliocene times, a medium-sized volcanic field of overlapping vents occurred in British Columbia's Interior Plateau. The distribution is assumed to engulf up to 50,000 km2 of the Pacific Northwest, forming a medium-sized large igneous province, of volume 3300 km3. Retrieved on 2012-09-22 Volcanism occurred as late as Oligocene time, but continues sporadically up to present. Eruptions were most vigorous 6- ...

Anahim Hotspot
The Anahim hotspot is a hypothesized hotspot in the Central Interior of British Columbia, Canada. It has been proposed as the candidate source for volcanism in the Anahim Volcanic Belt, a long chain of volcanoes and other magmatic features that have undergone erosion. This chain extends from the community of Bella Bella in the west to near the small city of Quesnel in the east. While most volcanoes are created by geological activity at tectonic plate boundaries, the Anahim hotspot is located hundreds of kilometres away from the nearest plate boundary. The hotspot was first proposed in the 1970s by three scientists who used John Tuzo Wilson's classic hotspot theory. This theory proposes that a single, fixed mantle plume builds volcanoes that then, cut off from their source by the movement of the North American Plate, become increasingly inactive and eventually erode over millions of years. A more recent theory, published in 2001 by the Geological Society of America, suggests th ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |
