The Barrier (1972 Film)
The Barrier is a lava dam retaining the Garibaldi Lake system in southwestern British Columbia, Canada. It is over thick and about long where it impounds the lake. The area below and adjacent to The Barrier is considered hazardous due to the unstable lava formation. Formation The Barrier was formed about 15,000–12,000 years ago when large lava flows emanated from Clinker Peak on the west shoulder of Mount Price. The large lava flowed towards the Cheakamus River valley. At the time of eruption, the valley was filled by glacial ice. The lava flow was stopped by the ice and ponded, eventually cooling to form an ice-marginal lava flow. When the ice melted away, the ice-cooled lava-flow front formed a precipitous cliff; water ponded behind the lava dam, forming Garibaldi Lake. Rubble Creek boulder field The unstable lava formation of The Barrier has in the past unleashed several debris flows in the area below Garibaldi Lake. The most recent major landslide in 1855-1856 for ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rubble Creek
Rubble Creek is a creek in southwestern British Columbia, Canada. It flows northwest from Garibaldi Lake into the Cheakamus River near the abandoned settlement of Garibaldi Giuseppe Maria Garibaldi ( , ;In his native Ligurian language, he is known as ''Gioxeppe Gaibado''. In his particular Niçard dialect of Ligurian, he was known as ''Jousé'' or ''Josep''. 4 July 1807 – 2 June 1882) was an Italian general, pat ....

Howe Sound
Howe Sound (french: Baie (de /d')Howe, squ, Átl'ka7tsem, Nexwnéwu7ts, Txwnéwu7ts) is a roughly triangular sound, that joins a network of fjords situated immediately northwest of Vancouver, British Columbia. It was designated as a UNESCO Biosphere Reserve in 2021. Geography Howe Sound's mouth at the Strait of Georgia is situated between West Vancouver and the Sunshine Coast. The sound is triangular, opening to the southwest into the Strait of Georgia, and extends northeast to its head at Squamish. There are several islands in the sound, three of which are large and mountainous in their own right. The steep-sided mainland shores funnel the breezes as the daily thermals build the wind to or more at the northern end of the sound on a typical summer day. A small outcrop of volcanic rock is located on the eastern shore of Howe Sound called the Watts Point volcanic centre. History The history of Howe Sound begins with the Indigenous people, the Squamish and Shishalh, who h ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Garibaldi Ranges
The Garibaldi Ranges are the next-to-southwesternmost subdivision of the Pacific Ranges of the Coast Mountains; only the North Shore Mountains are farther southwest. They lie between the valley formed by the pass between the Cheakamus River and Green River on the west (the location of the Resort Municipality of Whistler) and the valley of the Lillooet River on the east, and extend south into Maple Ridge, an eastern suburb of Vancouver, and the northern District of Mission. To their south are the North Shore Mountains overlooking Vancouver while to their southeast are the Douglas Ranges. They take their name indirectly from Mount Garibaldi on the western side of the range, which is the namesake of Garibaldi Provincial Park. Their southern end between the upper Stave River and Pitt Lake is north of the municipality of Maple Ridge, and forms Golden Ears Provincial Park (which was originally part of Garibaldi Park). Their most famous mountain, The Black Tusk, is not among t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sea-to-Sky Corridor
The Sea-to-Sky Corridor, often referred to as the Corridor or the Sea to Sky Country, is a region in British Columbia spreading from Horseshoe Bay through Whistler to the Pemberton Valley and sometimes beyond to include Birken and D'Arcy. From Whistler on up, the region overlaps with the older and more historic Lillooet Country, of which Squamish, at the region's centre, was once the southward extension in the days when it was the rail-port terminus from the Interior, via Lillooet, and accessible from the Lower Mainland only by sea. Most of the region is in the Squamish-Lillooet Regional District, although south of Britannia Beach a small part of the region is in the Greater Vancouver Regional District. The term "Corridor" refers to the alignment of the region's towns along Highway 99, also known as the Sea to Sky Highway, which links together the regions' three main centres - Squamish, Whistler and Pemberton. There is little development other than resource extraction ou ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Natural Hazards In British Columbia
Nature, in the broadest sense, is the physical world or universe. "Nature" can refer to the phenomena of the physical world, and also to life in general. The study of nature is a large, if not the only, part of science. Although humans are part of nature, human activity is often understood as a separate category from other natural phenomena. The word ''nature'' is borrowed from the Old French ''nature'' and is derived from the Latin word ''natura'', or "essential qualities, innate disposition", and in ancient times, literally meant "birth". In ancient philosophy, ''natura'' is mostly used as the Latin translation of the Greek word ''physis'' (φύσις), which originally related to the intrinsic characteristics of plants, animals, and other features of the world to develop of their own accord. The concept of nature as a whole, the physical universe, is one of several expansions of the original notion; it began with certain core applications of the word φύσις by pre-So ...

Volcanic Dams
A volcano is a rupture in the crust of a planetary-mass object, such as Earth, that allows hot lava, volcanic ash, and gases to escape from a magma chamber below the surface. On Earth, volcanoes are most often found where list of tectonic plates, tectonic plates are divergent boundary, diverging or convergent boundary, converging, and most are found underwater. For example, a mid-ocean ridge, such as the Mid-Atlantic Ridge, has volcanoes caused by divergent tectonic plates whereas the Pacific Ring of Fire has volcanoes caused by convergent tectonic plates. Volcanoes can also form where there is stretching and thinning of the crust's plates, such as in the East African Rift and the Wells Gray-Clearwater volcanic field and Rio Grande rift in North America. Volcanism away from plate boundaries has been postulated to arise from upwelling diapirs from the core–mantle boundary, deep in the Earth. This results in hotspot (geology), hotspot volcanism, of which the Hawaiian hotspot i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cliffs Of Canada
In geography and geology, a cliff is an area of rock which has a general angle defined by the vertical, or nearly vertical. Cliffs are formed by the processes of weathering and erosion, with the effect of gravity. Cliffs are common on coasts, in mountainous areas, escarpments and along rivers. Cliffs are usually composed of rock that is resistant to weathering and erosion. The sedimentary rocks that are most likely to form cliffs include sandstone, limestone, chalk, and dolomite. Igneous rocks such as granite and basalt also often form cliffs. An escarpment (or scarp) is a type of cliff formed by the movement of a geologic fault, a landslide, or sometimes by rock slides or falling rocks which change the differential erosion of the rock layers. Most cliffs have some form of scree slope at their base. In arid areas or under high cliffs, they are generally exposed jumbles of fallen rock. In areas of higher moisture, a soil slope may obscure the talus. Many cliffs also fea ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dams In British Columbia
A dam is a barrier that stops or restricts the flow of surface water or underground streams. Reservoirs created by dams not only suppress floods but also provide water for activities such as irrigation, human consumption, industrial use, aquaculture, and navigability. Hydropower is often used in conjunction with dams to generate electricity. A dam can also be used to collect or store water which can be evenly distributed between locations. Dams generally serve the primary purpose of retaining water, while other structures such as floodgates or levees (also known as dikes) are used to manage or prevent water flow into specific land regions. The earliest known dam is the Jawa Dam in Jordan, dating to 3,000 BC. The word ''dam'' can be traced back to Middle English, and before that, from Middle Dutch, as seen in the names of many old cities, such as Amsterdam and Rotterdam. History Ancient dams Early dam building took place in Mesopotamia and the Middle East. Dams were used ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Garibaldi Provincial Park
Garibaldi Provincial Park, also called Garibaldi Park, is a wilderness park located on the coastal mainland of British Columbia, Canada, 70 kilometres (43.5 mi) north of Vancouver. It was established in 1920 and named a Class A Provincial Park of British Columbia in 1927. The park is a popular destination for outdoor recreation, with over 30,000 overnight campers and over 106,000 day users in the 2017/2018 season. Garibaldi Park spans an area of over 1,950 square kilometres (753 sq mi), encompassing a majority of the Garibaldi Range mountains. The western side of the park is highly trafficked by the public due to access provided by the nearby Sea to Sky Highway to destinations in the park such as Elfin Lakes, Garibaldi Lake, The Black Tusk, Cheakamus Lake, and Wedgemount Lake. The eastern wilderness of the park is harder to access and therefore more remote than its western counterpart. To the south, Garibaldi Park connects with Golden Ears Provincial Park and ...

Volcanism In 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 be ...

Cascade Volcanoes
The Cascade Volcanoes (also known as the Cascade Volcanic Arc or the Cascade Arc) are a number of volcanoes in a volcanic arc in western North America, extending from southwestern British Columbia through Washington and Oregon to Northern California, a distance of well over . The arc formed due to subduction along the Cascadia subduction zone. Although taking its name from the Cascade Range, this term is a geologic grouping rather than a geographic one, and the Cascade Volcanoes extend north into the Coast Mountains, past the Fraser River which is the northward limit of the Cascade Range proper. Some of the major cities along the length of the arc include Portland, Seattle, and Vancouver, and the population in the region exceeds 10 million. All could be potentially affected by volcanic activity and great subduction-zone earthquakes along the arc. Because the population of the Pacific Northwest is rapidly increasing, the Cascade volcanoes are some of the most dangerous, du ...

Garibaldi Volcanic Belt
The Garibaldi Volcanic Belt is a northwest–southeast trending volcanic chain in the Pacific Ranges of the Coast Mountains that extends from Watts Point in the south to the Ha-Iltzuk Icefield in the north. This chain of volcanoes is located in southwestern British Columbia, Canada. It forms the northernmost segment of the Cascade Volcanic Arc, which includes Mount St. Helens and Mount Baker. Most volcanoes of the Garibaldi chain are dormant stratovolcanoes and subglacial volcanoes that have been eroded by glacial ice. Less common volcanic landforms include cinder cones, volcanic plugs, lava domes and calderas. These diverse formations were created by different styles of volcanic activity, including Peléan and Plinian eruptions. Eruptions along the length of the chain have created at least three major volcanic zones. The first began in the Powder Mountain Icefield 4.0 million years ago. Mount Cayley began its formation during this period. Multiple eruptions from 2.2& ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
