Lava Lake (British Columbia)
Lava Lake is a lava dammed lake located in northwestern British Columbia, Canada. The lake lies within the Nisga'a Memorial Lava Beds Provincial Park, which includes fishing, hiking and other features. Formation Lava Lake increased in size and depth when lava from the Tseax Cone dammed the Tseax River in the 18th century. The flow subsequently traveled north to the Nass River, where it filled the flat valley floor for an additional , making the entire lava flow approximately long. This is one of Canada's youngest lava flows.

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] |
Tseax River
The Ksi Sii Aks (formerly Tseax River) is a tributary of the Nass River in northwestern British Columbia, Canada. It is most notable as the namesake of Tseax Cone, a volcano within its basin that was responsible for an eruption in the 17th century that killed 2,000 Nisga'a people. Prior to the eruption, the Nisga'a name for this river was Ksi Gimwits'ax. Buried by the eruption, it eventually resurfaced. The Nisga'a recognized it as the same stream but renamed it Ksi Sii Aks: means "new body of water". As prescribed by terms of the Nisga'a Treaty The Nisga'a Final Agreement, also known as the Nisga'a Treaty, is a treaty that was settled between the Nisg̱a'a, the government of British Columbia, and the Government of Canada that was signed on 27 May 1998 and came into effect on May 11, 2000 ..., the Tseax River is now officially named the Ksi Sii Aks. Ksi Sii Aks flows about north to the Nass River.Length measured using Google Maps path tool, BCGNIS coordinates, topographic maps, ...

Lava Dammed Lakes
Lava is molten or partially molten rock (magma) that has been expelled from the interior of a terrestrial planet (such as Earth) or a moon onto its surface. Lava may be erupted at a volcano or through a fracture in the crust, on land or underwater, usually at temperatures from . The volcanic rock resulting from subsequent cooling is also often called ''lava''. A lava flow is an outpouring of lava during an effusive eruption. (An explosive eruption, by contrast, produces a mixture of volcanic ash and other fragments called tephra, not lava flows.) The viscosity of most lava is about that of ketchup, roughly 10,000 to 100,000 times that of water. Even so, lava can flow great distances before cooling causes it to solidify, because lava exposed to air quickly develops a solid crust that insulates the remaining liquid lava, helping to keep it hot and inviscid enough to continue flowing. The word ''lava'' comes from Italian and is probably derived from the Latin word ''labes'' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Volcanism In Canada
Volcanism, 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 Canada, 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 th ...

Lava Lakes
Lava lakes are large volumes of molten lava, usually basaltic, contained in a volcanic vent, crater, or broad depression. The term is used to describe both lava lakes that are wholly or partly molten and those that are solidified (sometimes referred to as ''frozen lava lakes''). Formation Lava lakes can form in three ways: *from one or more vents in a crater that erupts enough lava to partially fill the crater; or *when lava pours into a crater or broad depression and partially fills the crater; or *atop a new vent that erupts lava continuously for a period of several weeks or more and slowly builds a crater progressively higher than the surrounding ground. Behaviors Lava lakes occur in a variety of volcanic systems, ranging from the basaltic Erta Ale lake in Ethiopia and the basaltic andesite volcano of Villarrica, Chile, to the unique phonolitic lava lake at Mt. Erebus, Antarctica. Lava lakes have been observed to exhibit a range of behaviours. A "constantly circula ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nass River
The Nass River is a river in northern British Columbia, Canada. It flows from the Coast Mountains southwest to Nass Bay, a sidewater of Portland Inlet, which connects to the North Pacific Ocean via the Dixon Entrance. Nass Bay joins Portland Inlet just south of Observatory Inlet. The English name "Nass" is derived from the Tlingit name ''Naas'' which means "intestines" or "guts" in reference to the river's large food capacity in its fish (Naish & Story 1963; Leer, Hitch, & Ritter 2001). Can also be a Tlingit word for "food depot". Former spellings are Naas and Nasse. The Nisga'a name for the river is ''K'alii Aksim Lisims'' "Lisims (river name) Valley". The Gitxsan name is ''Git-Txaemsim'' meaning People of Txeemsim (Raven or Trickster); ''Xsitxemsem'' in the dialect of the Gitanyow). ''Lisims'' means "murky" in Nisga'a, referring to the river's silt-laden flow. The last of the river are navigable. The river is a commercially valuable salmon fishery. The basin of the Nass ...

Tseax Cone
The Tseax Cone ( ), also called the Tseax River Cone or the Aiyansh Volcano, is a young and active cinder cone and adjacent lava flows associated with the Nass Ranges and the Northern Cordilleran Volcanic Province. It is located east of Crater Creek at outlet of Melita Lake, southeast of Gitlakdamix and north of Terrace, British Columbia, Canada. The volcano is in a valley above and east of the Tseax River, about south of the river's junction with the larger Nass River. The Tseax Cone is one of the most accessible volcanic centres in British Columbia. Geology The Tseax Cone is in the southern part of the Northern Cordilleran Volcanic Province and is therefore part of the Ring of Fire. It has been the site of some of the youngest volcanic eruptions in Canada. It has been active at least twice in the past few hundred years and other remnants of lava flows exist in the area. It is in diameter at its base and rests on the remnants of an earlier and somewhat larger, dissected, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Volcanic Dam
A volcanic dam is a type of natural dam produced directly or indirectly by volcanism, which holds or temporarily restricts the flow of surface water in existing streams, like a man-made dam. There are two main types of volcanic dams, those created by the flow of molten lava, and those created by the primary or secondary deposition of pyroclastic material and debris. This classification generally excludes other, often larger and longer lived dam-type geologic features, separately termed crater lakes, although these volcanic centers may be associated with the source of material for volcanic dams, and the lowest portion of its confining rim may be considered as such a dam, especially if the lake level within the crater is relatively high. Volcanic dams generally occur worldwide, in association with former and active volcanic provinces, and are known to have existed in the geologic record, in historic times and occur in the present day. Their removal or failure is similarly recorded ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Hiking
Hiking is a long, vigorous walk, usually on trails or footpaths in the countryside. Walking for pleasure developed in Europe during the eighteenth century.AMATO, JOSEPH A.

Religious pilgrimages have existed much longer but they involve walking long distances for a spiritual purpose associated with specific religions. "Hiking" is the preferred term in Canada and the United States; the term "walking" is used in these regions for shorter, particularly urban walks. In the United Kingdom and the Republic of Ireland, the word "walking" describes all forms of walking, whether it is a walk in the park or backpacking in the Alps. The word hiking is also often used in the UK, along with rambling , hillwalking, and fell walking (a term mostly used for hillwalking in northern England). The term bushwalking is end ...
