Pouce Coupe River
The Pouce Coupe River is a major tributary of the Peace River (Canada), Peace River in Alberta and British Columbia, Canada. Its name is officially spelled ''Pouce Coupé River'', but it is commonly written without the acute accent. Originating in Alberta's Saddle Hills County, it flows into British Columbia's Peace River Regional District, British Columbia, Peace River Regional District, then returns in Alberta in Saddle Hill County, where it empties into the Peace River. The region of Pouce Coupe Prairie, from which the river and village of Pouce Coupe, British Columbia, Pouce Coupe take their names, was called that for a Dunneza, Beaver Indian Chief named 'Pouscapee'. The first European settler in the region was Hector Tremblay, who built a cabin there in 1898. Tremblay, of French people, French origin, translated 'Pouskapee's Prairie' into the nearest French words of similar sound (, meaning "cut thumb" or "cut-off thumb"). Course The Pouce Coupe originates in a small lake i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Marine (ocean)
The ocean (also the sea or the world ocean) is the body of salt water that covers approximately 70.8% of the surface of Earth and contains 97% of Earth's water.

Muskiki Formation
The Muskiki Formation is a stratigraphical unit of Late Cretaceous age in the Western Canadian Sedimentary Basin. The formation is named after Muskiki Lake and Muskiki Creek, a tributary of the Cardinal River, and was first described in an outcrop along the Thistle Creek, north of Muskiki Lake, in the Bighorn Range, by D.F. Stott in 1963. The name is of Cree origin ("maskihkîy"), meaning ''medicine''. Lithology The Muskiki Formation is composed of shale with pebbly mudstone. Poorly sorted sandstone and concretionary beds also occur. In the western areal it becomes more silty. Distribution The Muskiki Formation is thick at its type locality at Thistle Creek. It thins out towards the south and east. It occurs in the Canadian Rockies foothills from the Highwood River in the south to the Berland River, north of the Athabasca River and into north-eastern British Columbia. Relationship to other units The Muskiki Formationis is part of the Smoky Group. It is conformably underlain by ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Transgression (geology)
A marine transgression is a geologic event during which sea level rises relative to the land and the shoreline moves toward higher ground, which results in flooding. Transgressions can be caused by the land sinking or by the ocean basins filling with water or decreasing in capacity. Transgressions and regressions may be caused by tectonic events such as orogenies, severe climate change such as ice ages or isostatic adjustments following removal of ice or sediment load. During the Cretaceous, seafloor spreading created a relatively shallow Atlantic basin at the expense of deeper Pacific basin. That reduced the world's ocean basin capacity and caused a rise in sea level worldwide. As a result of the sea level rise, the oceans transgressed completely across the central portion of North America and created the Western Interior Seaway from the Gulf of Mexico to the Arctic Ocean. The opposite of transgression is regression in which the sea level falls relative to the land and expo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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.

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] |
Canadian Rockies
The Canadian Rockies (french: Rocheuses canadiennes) or Canadian Rocky Mountains, comprising both the Alberta Rockies and the British Columbian Rockies, is the Canadian segment of the North American Rocky Mountains. It is the easternmost part of the Canadian Cordillera, which is the northern segment of the North American Cordillera, the expansive system of interconnected mountain ranges between the Interior Plains and the Pacific Coast that runs northwest–southeast from central Alaska to the Isthmus of Tehuantepec in Mexico. Canada officially defines the Rocky Mountains system as the mountain chains east of the Rocky Mountain Trench extending from the Liard River valley in northern British Columbia to the Albuquerque Basin in New Mexico, not including the Mackenzie, Richardson and British Mountains/Brooks Range in Yukon and Alaska (which are all included as the "Arctic Rockies" in the United States' definition of the Rocky Mountains system).

Northern Alberta
Northern Alberta is a geographic region located in the Canadian province of Alberta. An informally defined cultural region, the boundaries of Northern Alberta are not fixed. Under some schemes, the region encompasses everything north of the centre of the Calgary–Edmonton Corridor, including most of the province's landmass as well as its capital, Edmonton. Other schemes place Edmonton and its surrounding farmland in Central Alberta, limiting Northern Alberta to the northern half of the province, where forestry, oil, and gas are the dominant industries. Its primary industry is oil and gas, with large heavy oil reserves being exploited at the Athabasca oil sands and Wabasca area in the east of the region. Natural gas is extracted in Peace region and Chinchaga-Rainbow areas in the west, and forestry and logging are also developed in the boreal forests of this region. As of 2011, the region had a population of approximately 386,000. Geography Various definitions exist of North ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Cardium Formation
The Cardium Formation is a stratigraphic unit of Late Cretaceous age in the Western Canada Sedimentary Basin. It takes the name from the fossilized heart-shaped cockle shells in the family Cardiidae (from Greek ''kardiā'', "heart") present. It was first described along the Bow River banks by James Hector in 1895.as reported in Whiteaves, J.F. 1895, Some of the Cretaceous fossils collected during Captain Palliser's explorations in British North America in 1857-60. Proc. and Trans., Royal Society of Canada, 2nd Ser., vol. 1, pp. 110. It is present throughout western Alberta and in northeastern British Columbia, and it is a major source of petroleum and natural gas. Lithology The Cardium Formation is composed primarily of beds of massive, fine-grained to conglomeratic sandstone, which are separated by thick layers of shale.

Natural Gas
Natural gas (also called fossil gas or simply gas) is a naturally occurring mixture of gaseous hydrocarbons consisting primarily of methane in addition to various smaller amounts of other higher alkanes. Low levels of trace gases like carbon dioxide, nitrogen, hydrogen sulfide, and helium are also usually present. Natural gas is colorless and odorless, so odorizers such as mercaptan (which smells like sulfur or rotten eggs) are commonly added to natural gas supplies for safety so that leaks can be readily detected. Natural gas is a fossil fuel and non-renewable resource that is formed when layers of organic matter (primarily marine microorganisms) decompose under anaerobic conditions and are subjected to intense heat and pressure underground over millions of years. The energy that the decayed organisms originally obtained from the sun via photosynthesis is stored as chemical energy within the molecules of methane and other hydrocarbons. Natural gas can be burned fo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sandstone
Sandstone is a clastic sedimentary rock composed mainly of sand-sized (0.0625 to 2 mm) silicate grains. Sandstones comprise about 20–25% of all sedimentary rocks. Most sandstone is composed of quartz or feldspar (both silicates) because they are the most resistant minerals to weathering processes at the Earth's surface. Like uncemented sand, sandstone may be any color due to impurities within the minerals, but the most common colors are tan, brown, yellow, red, grey, pink, white, and black. Since sandstone beds often form highly visible cliffs and other topographic features, certain colors of sandstone have been strongly identified with certain regions. Rock formations that are primarily composed of sandstone usually allow the percolation of water and other fluids and are porous enough to store large quantities, making them valuable aquifers and petroleum reservoirs. Quartz-bearing sandstone can be changed into quartzite through metamorphism, usually related to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
