Ash Mountain (British Columbia)
Ash Mountain is the highest summit in the Tuya Range of the Stikine Ranges in northcentral British Columbia, Canada, located immediately north of High Tuya Lake at the north end of Tuya Mountains Provincial Park. It is one of the six tuyas clustered close to Tuya Lake. The base of the volcano comprises pillow lava and hyaloclastite indicating that the volcano formed beneath ice or under a large lake. The volcano comprises loose debris as well as dikes of basaltic rock that intruded into the volcanic pile. Other tuyas in the area include Tuya Butte, South Tuya and Mathews Tuya, although most of the group of tuyas are unnamed.

Tuya Range
The Tuya Range is a mountain range in the Stikine Ranges of the Cassiar Mountains in the far north of the Canadian province of British Columbia, near its border with the Yukon, Yukon Territory and to the southwest of Watson Lake, Yukon, which is the nearest major settlement. Boundaries and landforms The northern and northwest side of the range is drained by tributaries of the Cottonwood River (Tuya), Cottonwood River; the southern and southwestern flank is formed by Tuya Lake and its tributary, Butte Creek (British Columbia), Butte Creek, while the southeast flank is formed by the Cottonwood River and its tributaries (the Cottonwood is a tributary of the Dease River, the Tuya of the Stikine River, Stikine). The range's northern boundary is formed by the upper Jennings River, a tributary of the Teslin River system which is part of the Yukon River drainage. Thus, the triple divide between the Mackenzie River, Mackenzie, Stikine River, Stikine, and Yukon River basins lies within the ...

Debris
Debris (, ) is rubble, wreckage, ruins, litter and discarded garbage/refuse/trash, scattered remains of something destroyed, or, as in geology, large rock fragments left by a melting glacier, etc. Depending on context, ''debris'' can refer to a number of different things. The first apparent use of the French word in English is in a 1701 description of the army of Prince Rupert upon its retreat from a battle with the army of Oliver Cromwell, in England. Disaster In disaster scenarios, tornadoes leave behind large pieces of houses and mass destruction overall. This debris also flies around the tornado itself when it is in progress. The tornado's winds capture debris it kicks up in its wind orbit, and spins it inside its vortex. The tornado's wind radius is larger than the funnel itself. Tsunamis and hurricanes also bring large amounts of debris, such as Hurricane Katrina in 2005 and Hurricane Sandy in 2012. Earthquakes rock cities to rubble debris. Geological In geology, debri ...

Northern Cordilleran Volcanic Province
The Northern Cordilleran Volcanic Province (NCVP), formerly known as the Stikine Volcanic Belt, is a geologic province defined by the occurrence of Miocene to Holocene volcanoes in the Pacific Northwest of North America. This belt of volcanoes extends roughly north-northwest from northwestern British Columbia and the Alaska Panhandle through Yukon to the Southeast Fairbanks Census Area of far eastern Alaska, in a corridor hundreds of kilometres wide. It is the most recently defined volcanic province in the Western Cordillera. It has formed due to extensional cracking of the North American continent—similar to other on-land extensional volcanic zones, including the Basin and Range Province and the East African Rift. Although taking its name from the Western Cordillera, this term is a geologic grouping rather than a geographic one. The southmost part of the NCVP has more, and larger, volcanoes than does the rest of the NCVP; further north it is less clearly delineated, describin ...

Two-thousanders Of British Columbia
Two-thousanders are mountains that have a height of at least 2,000 metres above sea level, but less than 3,000 metres. The term is used in Alpine circles, especially in Europe (e.g. German: ''Zweitausender''). The two photographs show two typical two-thousanders in the Alps that illustrate different types of mountain. The Säuling (top) is a prominent, individual peak, whereas the Schneeberg (bottom) is an elongated limestone massif. In ranges like the Allgäu Alps, the Gesäuse or the Styrian-Lower Austrian Limestone Alps the mountain tour descriptions for mountaineers or hikers commonly include the two-thousanders, especially in areas where only a few summits exceed this level. Examples from these regions of the Eastern Alps are: * the striking Nebelhorn (2,224 m) near Oberstdorf or the Säuling (2,047 m) near Neuschwanstein, * the Admonter Reichenstein (2,251 m), Eisenerzer Reichenstein (2,165 m), Großer Pyhrgas (2,244 m) or Hochtor (2,369&n ...

Volcanoes 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] |
Volcanic History Of The Northern Cordilleran Volcanic Province
The volcanic history of the Northern Cordilleran Volcanic Province presents a record of volcanic activity in northwestern British Columbia, central Yukon and the U.S. state of easternmost Alaska. The volcanic activity lies in the northern part of the Western Cordillera of the Pacific Northwest region of North America. Extensional cracking of the North American Plate in this part of North America has existed for millions of years. Continuation of this continental rifting has fed scores of volcanoes throughout the Northern Cordilleran Volcanic Province over at least the past 20 million years (see Geology of the Pacific Northwest) and occasionally continued into geologically recent times. Eruptive activity in the Northern Cordilleran Volcanic Province throughout its 20 million year history has been mainly the production of alkaline lavas, including alkaline basalts. A range of alkaline rock types not commonly found in the Western Cordillera are regionally widespread in the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Volcanism Of Western Canada
Volcanism of Western Canada has produced lava flows, lava plateaus, lava domes, cinder cones, stratovolcanoes, shield volcanoes, greenstone belts, submarine volcanoes, calderas, diatremes and maars, along with examples of more less common volcanic forms such as tuyas and subglacial mound A subglacial mound (SUGM) is a type of subglacial volcano.

Mathews Tuya
Mathews Tuya is a tuya in northcentral British Columbia. It is one of the six tuyas close to Tuya Lake. It has been partly glaciated and Ar-Ar geochronology shows that is it about 730,000 years old. It mainly comprises palagonitized tephra (tuff, lapilli tuff, tuff-breccia) but also has a few dykes and jointed lava flows on its flanks. The top still has flat-lying lava flows erupted after the tephra pile grew above the surface of the enclosing lake. The other volcanoes in the area include Tuya Butte, South Tuya and Ash Mountain. The volcanoes in the region form part of the Northern Cordilleran Volcanic Province.

Tuya Butte
Tuya Butte is a tuya in the Tuya Range of north-central British Columbia, Canada. It is a bit less isolated from other ranges than neighbouring Mount Josephine. Some of the other volcanoes in the area include South Tuya, Ash Mountain, and Mathews Tuya. Tuya Butte was the first tuya analyzed in the geological literature, and its name has since become standard worldwide among volcanologists in referring to and writing about tuyas. The Tuya Mountains Provincial Park was recently established to protect this unusual landscape, which lies north of Tuya Lake and south of the Jennings River near the boundary with the Yukon Territory. Tuya Butte is regarded as among the best examples of this landform outside Iceland and Antarctica. Tuya Butte was named by Canadian volcanologist Bill Mathews in association with adjacent Tuya Lake and Butte Lake. The term ''tuya'' may be derived from a Tahltan word.
