Skukum Group
The Skukum Group is a 55-million-year-old volcanic group in northern British Columbia and southern Yukon, Canada. It consists of discrete calderas in a linear range from the south end of Atlin Lake to Bennett Lake, then to Aishihik Lake. The cluster of rocks crowds the Mount Skukum gold deposit southwest of Whitehorse. One of the calderas within the group is the Bennett Lake Volcanic Complex.

A volcanic group is a stratigraphic group consisting of volcanic strata. They can be in the form of volcanic fields, volcanic complexes and cone A cone is a three-dimensional geometric shape that tapers smoothly from a flat base (frequently, though not necessarily, circular) to a point called the apex or vertex. A cone is formed by a set of line segments, half-lines, or lines con ... clusters. Notable volcanic groups See also * * * * * * * References {{reflist Volcanic landforms Volcanoes ...

Volcanism Of Canada
Volcanic activity is a major part of the geology of Canada and is characterized by many types of volcanic landform, including lava flows, volcanic plateaus, lava domes, cinder cones, stratovolcanoes, shield volcanoes, submarine volcanoes, calderas, diatremes, and maars, along with less common volcanic forms such as tuyas and subglacial mounds. Though Canada's volcanic history dates back to the Precambrian eon, at least 3.11 billion years ago, when its part of the North American continent began to form, volcanism continues to occur in Western and Northern Canada in modern times, where it forms part of an encircling chain of volcanoes and frequent earthquakes around the Pacific Ocean called the Pacific Ring of Fire. Because volcanoes in Western and Northern Canada are in relatively remote and sparsely populated areas and their activity is less frequent than with other volcanoes around the Pacific Ocean, Canada is commonly thought to occupy a gap in the Ring of Fire between the ...

Eocene Calderas
The Eocene ( ) Epoch is a geological epoch that lasted from about 56 to 33.9 million years ago (mya). It is the second epoch of the Paleogene Period in the modern Cenozoic Era. The name ''Eocene'' comes from the Ancient Greek (''ēṓs'', "dawn") and (''kainós'', "new") and refers to the "dawn" of modern ('new') fauna that appeared during the epoch. The Eocene spans the time from the end of the Paleocene Epoch to the beginning of the Oligocene Epoch. The start of the Eocene is marked by a brief period in which the concentration of the carbon isotope 13C in the atmosphere was exceptionally low in comparison with the more common isotope 12C. The end is set at a major extinction event called the ''Grande Coupure'' (the "Great Break" in continuity) or the Eocene–Oligocene extinction event, which may be related to the impact of one or more large bolides in Siberia and in what is now Chesapeake Bay. As with other geologic periods, the strata that define the start and end of the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Atlin District
The Atlin District, also known as the Atlin Country, is a historical region located in the far northwestern corner of the Canadian province of British Columbia, centred on Atlin Lake and the gold-rush capital of the region, the town of Atlin. The term "Atlin District" was also used synonymously with the official administrative area named the Atlin Mining District, established during the gold-mining heyday contemporaneous with the Klondike Gold Rush. The region also includes adjoining Teslin and Tagish Lakes and the Bennett Lake area in the narrow strip of BC separating the Alaska Panhandle from the Yukon. The Atlin District is currently part of the Stikine Region in the regional district system (although it is not a regional district). The communities of the Atlin lakes district, as the area is casually called, are referred to in national weather reports as "the Southern Lakes", as in "Whitehorse and the Southern Lakes", although this also includes towns on the Yukon end of the ...

Calderas Of Yukon
A caldera ( ) is a large cauldron-like hollow that forms shortly after the emptying of a magma chamber in a volcano eruption. When large volumes of magma are erupted over a short time, structural support for the rock above the magma chamber is gone. The ground surface then collapses into the emptied or partially emptied magma chamber, leaving a large depression at the surface (from one to dozens of kilometers in diameter). Although sometimes described as a crater, the feature is actually a type of sinkhole, as it is formed through subsidence and collapse rather than an explosion or impact. Compared to the thousands of volcanic eruptions that occur each century, the formation of a caldera is a rare event, occurring only a few times per century. Only seven caldera-forming collapses are known to have occurred between 1911 and 2016. More recently, a caldera collapse occurred at Kīlauea, Hawaii in 2018.

Skookum
Skookum is a Chinook Jargon word that has historical use in the Pacific Northwest. It has a range of meanings, commonly associated with an English translation of "strong" or "monstrous". The word can mean "strong", "greatest", "powerful", "ultimate", or "brave". Something can be ''skookum'', meaning "strong" or "monstrously significant". When used in reference to another person, ''e.g.'', "he's skookum", it conveys connotations of reliability or a monstrous nature, as well as strength, size or hard-working. Derivative words ''Skookum house'' means 'jail' or 'prison' (cf. the English euphemism ''the big house'', but here meaning 'strong house'). ''Skookum tumtum'', lit. "strong heart", is generally translated as 'brave' or possibly 'good-hearted'. In the Chinook language, ''skookum'' is a verb auxiliary, used similarly to ''can'' or ''to be able''. Another compound, though fallen out of use in modern British Columbia English, is ''skookum lacasset'' or 'strongbox'. ''Skookumchuck ...

Bennett Lake Volcanic Complex
The Bennett Lake Volcanic Complex (BLVC) is a huge 50-million-year-old extinct caldera complex that spans across the British Columbia-Yukon border in Canada. It is located near the western end of the West Arm of Bennett Lake. The caldera complex is surrounded by granitic rocks containing pendants. It is located near the eastern contact of the Coast Plutonic Complex and the Whitehorse Trough. There are thick series of pyroclastic and epiclastic rocks at the caldera. Remnants of this huge caldera complex are preserved near Bennett Lake in the Coast Mountains. The complex compose the Skukum Group The Skukum Group is a 55-million-year-old volcanic group in northern British Columbia and southern Yukon, Canada.

British Columbia
British Columbia (commonly abbreviated as BC) is the westernmost province of Canada, situated between the Pacific Ocean and the Rocky Mountains. It has a diverse geography, with rugged landscapes that include rocky coastlines, sandy beaches, forests, lakes, mountains, inland deserts and grassy plains, and borders the province of Alberta to the east and the Yukon and Northwest Territories to the north. With an estimated population of 5.3million as of 2022, it is Canada's third-most populous province. The capital of British Columbia is Victoria and its largest city is Vancouver. Vancouver is the third-largest metropolitan area in Canada; the 2021 census recorded 2.6million people in Metro Vancouver. The first known human inhabitants of the area settled in British Columbia at least 10,000 years ago. Such groups include the Coast Salish, Tsilhqotʼin, and Haida peoples, among many others. One of the earliest British settlements in the area was Fort Victoria, established ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
