Coulee
Coulee, or coulée ( or ), is any of various different landforms, all of which are kinds of valleys or drainage zones. The word ''coulee'' comes from the Canadian French ''coulée'', from French ''couler'' 'to flow'. The term is often used interchangeably in the Great Plains for any of a number of water features, from ponds to creeks. In southern Louisiana the word ''coulée'' (also spelled ''coolie'') originally meant a gully or ravine usually dry or intermittent but becoming sizable during rainy weather. As stream channels were dredged or canalized, the term was increasingly applied to perennial streams, generally smaller than bayous. The term is also used for small ditches or canals in the swamp. In the northwestern United States, coulee is defined as a large, steep-walled, trench-like trough, which also include spillways and flood channels incised into the basalt plateau. Types and examples * The dry, braided channels formed by glacial drainage of the Scabland ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Grand Coulee
Grand Coulee is an ancient river bed in the U.S. state of Washington. This National Natural Landmark stretches for about southwest from Grand Coulee Dam to Soap Lake, being bisected by Dry Falls into the Upper and Lower Grand Coulee. Geological history Grand Coulee is a large coulee on the Columbia River Plateau. This area has underlying granite bedrock, formed deep in the Earth's crust 40 to 60 million years ago. The land periodically uplifted and subsided over millions of years giving rise to some small mountains and, eventually, an inland sea. From about 10 to 18 million years ago, a series of volcanic eruptions from the Grand Ronde Rift near the Idaho/Oregon/Washington/Montana border began to fill the inland sea with lava. In some places the volcanic basalt is thick. In other areas granite from the earlier mountains is still exposed. Starting about two million years ago, during the Pleistocene epoch, glaciation took place in the area. Large parts of northern North ...

Moses Coulee
Moses Coulee is a canyon in the Waterville plateau region of Douglas County, Washington. Moses Coulee is the second-largest and westernmost canyon of the Channeled Scablands, located about to the west of the larger Grand Coulee. This water channel is now dry, but during glacial periods, large outburst floods with discharges greater than carved the channel. While it's clear that glacial floodwaters passed through and contributed to the erosion of Moses Coulee, the age of those waters, thus the origins of the coulee are less clear. No clear connection between the head of the coulee and major flood routes to the north, east, or west is known. Some researchers propose that floods from glacial Lake Missoula formed Moses Coulee, while others suggest that subglacial floods from the Okanogan Lobe incised the canyon. The mouth of Moses Coulee discharges into the Columbia River. Two National Natural Landmarks were established in 1986 for features, notable as the best examples of their k ...

Channeled Scablands
The Channeled Scablands are a relatively barren and soil-free region of interconnected relict and dry flood channels, coulees and cataracts eroded into Palouse loess and the typically flat-lying basalt flows that remain after cataclysmic floods within the southeastern part of Washington state.Neuendorf, K.K.E., J.P. Mehl, Jr., and J.A. Jackson, eds. (2005) ''Glossary of Geology'' (5th ed.). Alexandria, Virginia, American Geological Institute. 779 pp. The Channeled Scablands were scoured by more than 40 cataclysmic floods during the Last Glacial Maximum and innumerable older cataclysmic floods over the last two million years. These floods were periodically unleashed whenever a large glacial lake broke through its ice dam and swept across eastern Washington and down the Columbia River Plateau during the Pleistocene epoch. The last of the cataclysmic floods occurred between 18,200 and 14,000 years ago.Balbas, A.M., Barth, A.M., Clark, P.U., Clark, J., Caffee, M., O'Connor, J., B ...

Lake Lenore (Washington)
Lake Lenore, also known as Lenore Lake, is located in Grant County, Washington, United States. It is a lake formed by the Missoula Floods in the lower Coulee just north of the town of Soap Lake, Washington. It is situated between Alkali Lake to the north and Soap Lake to the south. The lake is rather narrow, but long. The length of the lake runs north–south alongside State Route 17 leading from near the city of Soap Lake to Coulee City. The lake also consists of more than 7 islands. Lenore Canyon is a coulee associated with the development of the Scablands. One of the interesting areas around Lake Lenore is the Lenore Caves. Located at the northern end of the lake, the Lenore Caves are a series of overhangs along the cliffs at the lake. They exist in one of the largest volcanic regions on Earth. Lenore Caves The Lenore Caves were formed by the plucking of basalt from the walls of the coulees by the Missoula floods and are geologically different from most caverns. They ...

Bayou
In usage in the Southern United States, a bayou () is a body of water typically found in a flat, low-lying area. It may refer to an extremely slow-moving stream, river (often with a poorly defined shoreline), marshy lake, wetland, or creek. They typically contain brackish water highly conducive to fish life and plankton. Bayous are commonly found in the Gulf Coast region of the southern United States, especially in the Mississippi River Delta, though they also exist elsewhere. A bayou is often an anabranch or minor braid of a braided channel that is slower than the mainstem, often becoming boggy and stagnant. Though fauna varies by region, many bayous are home to crawfish, certain species of shrimp, other shellfish, and leeches, catfish, frogs, toads, salamanders, newts, American alligators, turtles, and snakes such as watersnakes, swampsnakes, mudsnakes, crayfish snakes, and cottonmouths. Common birds include anhingas, egrets, herons, spoonbills, as well as many oth ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Alberta 010
Alberta is a province in Canada. It is a part of Western Canada and is one of the three prairie provinces. Alberta is bordered by British Columbia to its west, Saskatchewan to its east, the Northwest Territories to its north, and the U.S. state of Montana to its south. Alberta and Saskatchewan are the only two landlocked Canadian provinces. 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 seasonal temperatures tend to swing rapidly because it is so arid. Those swings are less pronounced in western Alberta because of its occasional Chinook winds. Alberta is the fourth largest province by area, at , and the fourth most populous, with 4,262,635 residents. Alberta's capital is Edmonton; its largest city is Calgary. The two cities are Alberta's largest census metropolitan areas. More than half of Albertans live in Edmonton or Calgary, which encourages a cont ...
