Mount Payne
Mount Payne is a mountain summit located in the Canadian Cascades of southwestern British Columbia, Canada. It is situated southeast of Hope, northeast of Chilliwack Lake, and west of Silvertip Mountain, which is its nearest higher peak. Following Silvertip, Mount Payne is the second-highest summit in the Hope Mountains, a subset of the Skagit Range. The peak was first climbed in 1950 by J. Bussell, H. Genschorek, I. Kay, A. Melville, and W. Sparling. The peak was named for Damasus Payne, a Benedictine monk and mountaineer who tragically fell to his death on Edge Peak in 1978. Payne was responsible for naming mountains such as Mount Rohr and Mount Duke. He also carried all the materials for mass and communion up to the summit of Slesse Mountain to perform a ceremony to honor the victims of Trans-Canada Air Lines Flight 810. Mt. Payne's name was officially adopted May 7, 1984, by the Geographical Names Board of Canada. Precipitation runoff from the peak drains into headwaters o ...

Eaton Peak
Eaton Peak is a double summit mountain located in the Canadian Cascades of southwestern British Columbia, Canada. It is situated southeast of Hope, south of Mt. Grant, and northwest of Silvertip Mountain. The peak was first climbed in 1950 by J. Butcher, F. Rodgers, and E. Jenkins. The peak was named to honor Canadian Army Private Douglas B. Eaton (1911-1944), from nearby Chilliwack, who was killed in action in World War II. The mountain's name was officially adopted April 7, 1955, by the Geographical Names Board of Canada. Nearby Eaton Creek and Eaton Lake were named in memory of his younger brother, William, also killed in action a year earlier. Precipitation runoff from the peak drains into Silverhope Creek, a tributary of the Fraser River. Geology Eaton Peak is related to the Chilliwack batholith, which intruded the region 26 to 29 million years ago after the major orogenic episodes in the region. This is part of the Pemberton Volcanic Belt, an eroded volcanic belt th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Trans-Canada Air Lines Flight 810
Trans-Canada Air Lines Flight 810-9 was a Canadair North Star on a scheduled flight from Vancouver to Calgary (continuing to Regina, Winnipeg, and Toronto). The plane crashed into Mount Slesse near Chilliwack, British Columbia, Canada, on 9 December 1956 after encountering severe icing and turbulence over the mountains. All 62 people on board died, making it one of the deadliest airline crashes ever as of that date; it still ranks as the sixth deadliest air disaster in Canadian history. Due to the remoteness and difficulty of the terrain, the crash site was not located until the following May, when it was discovered by mountaineers Elfrida Pigou, Geoffrey Walker, and David Cathcart. Among the victims were five professional Canadian football players on their way home from the annual Shrine Game between the East and West all-stars in Vancouver. The remains are located in a highly inaccessible area and are protected from disturbance. Summary of events Flight 810-9 left ...

Fault (geology)
In geology, a fault is a planar fracture or discontinuity in a volume of rock across which there has been significant displacement as a result of rock-mass movements. Large faults within Earth's crust result from the action of plate tectonic forces, with the largest forming the boundaries between the plates, such as the megathrust faults of subduction zones or transform faults. Energy release associated with rapid movement on active faults is the cause of most earthquakes. Faults may also displace slowly, by aseismic creep. A ''fault plane'' is the plane that represents the fracture surface of a fault. A ''fault trace'' or ''fault line'' is a place where the fault can be seen or mapped on the surface. A fault trace is also the line commonly plotted on geologic maps to represent a fault. A ''fault zone'' is a cluster of parallel faults. However, the term is also used for the zone of crushed rock along a single fault. Prolonged motion along closely spaced faults can blur the ...

Pleistocene
The Pleistocene ( , often referred to as the ''Ice age'') is the geological Epoch (geology), epoch that lasted from about 2,580,000 to 11,700 years ago, spanning the Earth's most recent period of repeated glaciations. Before a change was finally confirmed in 2009 by the International Union of Geological Sciences, the cutoff of the Pleistocene and the preceding Pliocene was regarded as being 1.806 million years Before Present (BP). Publications from earlier years may use either definition of the period. The end of the Pleistocene corresponds with the end of the last glacial period and also with the end of the Paleolithic age used in archaeology. The name is a combination of Ancient Greek grc, label=none, πλεῖστος, pleīstos, most and grc, label=none, καινός, kainós (latinized as ), 'new'. At the end of the preceding Pliocene, the previously isolated North and South American continents were joined by the Isthmus of Panama, causing Great American Interchang ...

Farallon Plate
The Farallon Plate was an ancient oceanic plate. It formed one of the three main plates of Panthalassa, alongside the Phoenix Plate and Izanagi Plate, which were connected by a triple junction. The Farallon Plate began subducting under the west coast of the North American Plate—then located in modern Utah—as Pangaea broke apart and after the formation of the Pacific Plate at the centre of the triple junction during the Early Jurassic. It is named for the Farallon Islands, which are located just west of San Francisco, California. Over time, the central part of the Farallon Plate was completely subducted under the southwestern part of the North American Plate. The remains of the Farallon Plate are the Juan de Fuca, Explorer and Gorda Plates, subducting under the northern part of the North American Plate; the Cocos Plate subducting under Central America; and the Nazca Plate subducting under the South American Plate. The Farallon Plate is also responsible for transporting old i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Subduction
Subduction is a geological process in which the oceanic lithosphere is recycled into the Earth's mantle at convergent boundaries. Where the oceanic lithosphere of a tectonic plate converges with the less dense lithosphere of a second plate, the heavier plate dives beneath the second plate and sinks into the mantle. A region where this process occurs is known as a subduction zone, and its surface expression is known as an arc-trench complex. The process of subduction has created most of the Earth's continental crust. Rates of subduction are typically measured in centimeters per year, with the average rate of convergence being approximately two to eight centimeters per year along most plate boundaries. Subduction is possible because the cold oceanic lithosphere is slightly denser than the underlying asthenosphere, the hot, ductile layer in the upper mantle underlying the cold, rigid lithosphere. Once initiated, stable subduction is driven mostly by the negative buoyancy of the de ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Volcanic Belt
A volcanic belt is a large volcanically active region. Other terms are used for smaller areas of activity, such as volcanic fields. Volcanic belts are found above zones of unusually high temperature () where magma is created by partial melting of solid material in the Earth's crust and upper mantle. These areas usually form along tectonic plate boundaries at depths of . For example, volcanoes in Mexico and western North America are mostly in volcanic belts, such as the Trans-Mexican Volcanic Belt that extends from west to east across central-southern Mexico and the Northern Cordilleran Volcanic Province in western Canada. The deeply deformed and eroded remnants of ancient volcanic belts are found in volcanically inactive regions such as the Canadian Shield. It contains over 150 volcanic belts (now deformed and eroded down to nearly flat plains) that range from 600 to 1,200 million years old. These are zones of variably metamorphosed mafic to ultramafic volcanic sequences wit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pemberton Volcanic Belt
The Pemberton Volcanic Belt is an eroded Oligocene-Miocene volcanic belt at a low angle near the Mount Meager massif, British Columbia, Canada. The Garibaldi and Pemberton volcanic belts appear to merge into a single belt, although the Pemberton is older than the Garibaldi Volcanic Belt. The Pemberton Volcanic Belt is one of the geological formations comprising the Canadian Cascade Arc. It formed as a result of subduction of the former Farallon Plate. Features Features within the Pemberton Belt include: * Mount Barr Plutonic Complex ** Mount Barr *Chilliwack batholith **Slesse Mountain * Chipmunk Mountain * Coquihalla Mountain * Crevasse Crag *Franklin Glacier Complex * Salal Creek Pluton *Silverthrone Caldera See also *Garibaldi Volcanic Belt *Geology of the Pacific Northwest *Cascade Volcanoes *Volcanism of Canada *Volcanism of Western Canada Volcanism of Western Canada has produced lava flows, lava plateaus, lava domes, cinder cones, stratovolcanoes, shield vol ...

Orogeny
Orogeny is a mountain building process. An orogeny is an event that takes place at a convergent plate margin when plate motion compresses the margin. An ''orogenic belt'' or ''orogen'' develops as the compressed plate crumples and is uplifted to form one or more mountain ranges. This involves a series of geological processes collectively called orogenesis. These include both structural deformation of existing continental crust and the creation of new continental crust through volcanism. Magma rising in the orogen carries less dense material upwards while leaving more dense material behind, resulting in compositional differentiation of Earth's lithosphere ( crust and uppermost mantle). A synorogenic process or event is one that occurs during an orogeny. The word "orogeny" () comes from Ancient Greek (, , + , , ). Although it was used before him, the term was employed by the American geologist G. K. Gilbert in 1890 to describe the process of mountain-building as distinguished f ...

Chilliwack Batholith
The Chilliwack Batholith is a large batholith that forms much of the North Cascades in southwestern British Columbia, Canada and the U.S. state of Washington. The geological structure is named after the Chilliwack River Valley, where it outcrops in many places. It does not outcrop anywhere near the City of Chilliwack. The Chilliwack Batholith is part of the Pemberton Volcanic Belt and is the largest mass of exposed intrusive rock in the Cascade Volcanic Arc 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 Calif ....

Skagit River
The Skagit River ( ) is a river in southwestern British Columbia in Canada and northwestern Washington in the United States, approximately 150 mi (240 km) long. The river and its tributaries drain an area of 1.7 million acres (690,000 hectares) of the Cascade Range along the northern end of Puget Sound and flows into the sound. The Skagit watershed is characterized by a temperate, mid-latitude, maritime climate. Temperatures range widely throughout the watershed. Recorded temperatures at Newhalem range from a low of −6 °F (−21 °C) to a high of 109 °F (43 °C), with greater extremes likely in the mountains. The highest temperatures are commonly recorded in July; the lowest are in January. Course The Skagit River rises at Allison Pass in the Canadian Cascades of British Columbia. From there it flows northwest along the Crowsnest Highway, which follows the river into Manning Provincial Park. It turns abruptly south where it receives Snass ...
