Maligne Canyon
Maligne Canyon is a slot canyon located in the Jasper National Park near Jasper, Alberta, Canada. Eroded out of the Palliser Formation, the canyon measures over deep. Popular for sightseeing and exploration, the area contains waterfalls, underground stream outlets, birds and plant life. Geology While visually striking and unusual, slot canyons are a common occurrence within the northern Rocky Mountains. These canyons show the characteristics of karst topography and are common in this region due to the easily soluble nature of the limestone. Flowing out of Medicine Lake, the Maligne River flows about 15 kilometers upstream as a full size river, but as a losing stream, quickly disappears into seeps in the ground and completely vanishes from the surface not far from the lake for most of the year. The smaller streams that feed the valley below that point rebuild the river by the time it reaches the top of the canyon. The river drops down the canyon and intersects the bedrock layers wh ...

Slot Canyon
A slot canyon is a long, narrow channel or drainageway with sheer rock walls that are typically eroded into either sandstone or other sedimentary rock. A slot canyon has depth-to-width ratios that typically exceed 10:1 over most of its length and can approach 100:1. The term is especially used in the semiarid southwestern United States and particularly the Colorado Plateau. Slot canyons are subject to flash flooding and commonly contain unique ecological communities that are distinct from the adjacent, drier uplands. Some slot canyons can measure less than across at the top but drop more than to the floor of the canyon. Many slot canyons are formed in sandstone and limestone rock, although slot canyons in other rock types such as granite and basalt are possible. Even in sandstone and limestone, only a very small number of streams will form slot canyons due to a combination of the particular characteristics of the rock and regional rainfall. Around the world Slot canyons are foun ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Jasper National Park
Jasper National Park is a national park in Alberta, Canada. It is the largest national park within Alberta's Rocky Mountains spanning . It was established as a national park in 1930 and declared a UNESCO World Heritage Site in 1984. Its location is north of Banff National Park and west of Edmonton. The park contains the glaciers of the Columbia Icefield, springs, lakes, waterfalls and mountains. History First Nations The territory encompassed by what is now Jasper National Park has been inhabited since time immemorial by Nakoda, Cree, Secwépemc, and Dane-zaa peoples. Plainview projectile points have been found at the head of Jasper Lake, dating back to between 8000 and 7000 BCE. In the centuries between then and the establishment of the park, First Nations land use has fluctuated according to climatic variations over the long term, and according to cyclical patterns of ungulate population numbers, particularly elk, moose, mule deer, and occasionally caribou.

Alberta
Alberta ( ) is one of the thirteen provinces and territories of Canada. It is part of Western Canada and is one of the three prairie provinces. Alberta is bordered by British Columbia to the west, Saskatchewan to the east, the Northwest Territories (NWT) to the north, and the U.S. state of Montana to the south. It is one of the only two landlocked provinces in Canada (Saskatchewan being the other). The eastern part of the province is occupied by the Great Plains, while the western part borders the Rocky Mountains. The province has a predominantly continental climate but experiences quick temperature changes due to air aridity. Seasonal temperature swings are less pronounced in western Alberta due to occasional Chinook winds. Alberta is the fourth largest province by area at , and the fourth most populous, being home to 4,262,635 people. Alberta's capital is Edmonton, while Calgary is its largest city. The two are Alberta's largest census metropolitan areas. More tha ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Maligne River
The Maligne River ( ) is a medium-sized river in the Canadian Rockies. It runs through parts of Jasper National Park in Alberta, Canada. The Maligne is a major tributary of the Athabasca River. The river takes from the French word for malignant or wicked. It is theorised that a Belgian priest (Pieter Jan De Smet ) voyageur created this name in reference to the current of the river near its confluence with the Athabasca River. Geography The Maligne River begins south of Maligne Lake. Forming from the meltwater of Replica Peak, the river heads north, passing under Mount Mary Vaux, Lysfran Peak, Mount Unwin, and Mount Charleton before emptying into Maligne Lake. The Maligne River drains the north end of Maligne Lake and heads northwest to Medicine Lake. It then flows west, entering the Athabasca River.Mussio Ventures. ''Central Alberta Backroad Mapbook.'' Burnaby: Backroad Mapbooks (2002) Below Maligne Lake, it is a losing stream; its flow mostly disappears underground at Med ...

Palliser Formation
The Palliser Formation is a stratigraphic unit of Late Devonian (Famennian) age in the Western Canada Sedimentary Basin. It is a thick sequence of limestone and dolomitic limestone that is present in the Canadian Rockies and foothills of western Alberta. Tall cliffs formed of the Palliser Formation can be seen throughout Banff and Jasper National Parks. The formation was named for the Palliser Range in Banff National Park (which in turn took its name from John Palliser, the leader of the 1850s Palliser Expedition), by H.H. Beach in 1943.Beach, H.H., 1943. Moose Mountain and Morley map-areas, Alberta; Geological Survey of Canada, Memoir 236, 74 p.

Jasper, Alberta
Jasper is a specialized municipality and townsite in western Alberta within the Canadian Rockies. The townsite is in the Athabasca River valley and is the commercial centre of Jasper National Park. History Established in 1813, Jasper House was first a fur trade outpost of the North West Company, and later Hudson's Bay Company, on the York Factory Express trade route to what was then called "New Caledonia" (now British Columbia) and Fort Vancouver on the lower Columbia River. Jasper House was 35 km north of today's town of Jasper. Jasper Forest Park was established in 1907. The railway siding at the location of the future townsite was established by the Grand Trunk Pacific Railway in 1911 and originally named Fitzhugh after a Grand Trunk vice president (along the Grand Trunk's "alphabet" line). The Canadian Northern Railway began service to its ''Jasper Park'' station in 1912, about 700 m from GTP's Fitzhugh station. The townsite was surveyed in 1913 by H. Math ...

Canada
Canada is a country in North America. Its ten provinces and three territories extend from the Atlantic Ocean to the Pacific Ocean and northward into the Arctic Ocean, covering over , making it the world's second-largest country by total area. Its southern and western border with the United States, stretching , is the world's longest binational land border. Canada's capital is Ottawa, and its three largest metropolitan areas are Toronto, Montreal, and Vancouver. Indigenous peoples have continuously inhabited what is now Canada for thousands of years. Beginning in the 16th century, British and French expeditions explored and later settled along the Atlantic coast. As a consequence of various armed conflicts, France ceded nearly all of its colonies in North America in 1763. In 1867, with the union of three British North American colonies through Confederation, Canada was formed as a federal dominion of four provinces. This began an accretion of provinces an ...

Rocky Mountains
The Rocky Mountains, also known as the Rockies, are a major mountain range and the largest mountain system in North America. The Rocky Mountains stretch in straight-line distance from the northernmost part of western Canada, to New Mexico in the southwestern United States. Depending on differing definitions between Canada and the U.S., its northern terminus is located either in northern British Columbia's Terminal Range south of the Liard River and east of the Trench, or in the northeastern foothills of the Brooks Range/ British Mountains that face the Beaufort Sea coasts between the Canning River and the Firth River across the Alaska-Yukon border. Its southernmost point is near the Albuquerque area adjacent to the Rio Grande rift and north of the Sandia–Manzano Mountain Range. Being the easternmost portion of the North American Cordillera, the Rockies are distinct from the tectonically younger Cascade Range and Sierra Nevada, which both lie farther to its west. The ...

Karst Topography
Karst is a topography formed from the dissolution of soluble rocks such as limestone, dolomite, and gypsum. It is characterized by underground drainage systems with sinkholes and caves. It has also been documented for more weathering-resistant rocks, such as quartzite, given the right conditions. Subterranean drainage may limit surface water, with few to no rivers or lakes. However, in regions where the dissolved bedrock is covered (perhaps by debris) or confined by one or more superimposed non-soluble rock strata, distinctive karst features may occur only at subsurface levels and can be totally missing above ground. The study of ''paleokarst'' (buried karst in the stratigraphic column) is important in petroleum geology because as much as 50% of the world's hydrocarbon reserves are hosted in carbonate rock, and much of this is found in porous karst systems. Etymology The English word ''karst'' was borrowed from German in the late 19th century, which entered German much earlier. ...

Medicine Lake (Alberta)
Medicine Lake is located within Jasper National Park, Alberta, Canada. It is located approximately southeast of the townsite of Jasper, Alberta. Medicine Lake is approximately long and is a relatively shallow lake. The lake is part of the Maligne Valley watershed which is mainly glacial fed. Geology Medicine Lake is a geologic anomaly in the sense that it is not actually a lake but rather an area in which the Maligne River (flowing from Maligne Lake into the Athabasca River) backs up and suddenly disappears underground as a losing stream. During the summer months during intensified meltwater runoff the lake (which during the winter months is a meandering frozen river) fills to levels which fluctuate over time and with the runoff events. Much like a bathtub that is filled too fast for it to drain, it becomes laden with water (lake) until it can slowly drain as the tap flow (runoff) is reduced (river). The underground system is extensive and during the 1970s researchers used ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Losing Stream
A losing stream, disappearing stream, influent stream or sinking river is a stream or river that loses water as it flows downstream. The water infiltrates into the ground recharging the local groundwater, because the water table is below the bottom of the stream channel. This is the opposite of a more common ''gaining stream'' (or ''effluent stream'') which increases in water volume farther downstream as it gains water from the local aquifer. Losing streams are common in arid areas due to the climate which results in huge amounts of water evaporating from the river generally towards the mouth. Losing streams are also common in regions of karst topography where the streamwater may be completely captured by a cavern system, becoming a subterranean river. Examples There are many natural examples of subterranean rivers including: Bosnia and Herzegovina * Unac; Mušnica-Trebišnjica- Krupa/Ombla (Trebišnjica is considered to be one of the largest sinking rivers in the world; ...
