Purcell Trench
The Purcell Trench, also known as the Kootenay River Valley is a large valley on the western side of the northern part of North America's Rocky Mountains. The trench extends approximately from Lake Pend Oreille, Idaho, down the Kootenay River (north) to Kootenay Lake, up the north arm to Duncan Lake. It joins the Rocky Mountain Trench another northward at the south tip of Kinbasket Lake, in British Columbia.Doughty, P.T. & R.A.

Purcell And Rocky Mountain Trenches Within The US
Henry Purcell (, rare: September 1659 – 21 November 1695) was an English composer. Purcell's style of Baroque music was uniquely English, although it incorporated Italian and French elements. Generally considered among the greatest English opera composers, Purcell is often linked with John Dunstaple and William Byrd as England's most important early music composers. No later native-born English composer approached his fame until Edward Elgar, Ralph Vaughan Williams, Gustav Holst, William Walton and Benjamin Britten in the 20th century. Life and work Early life Purcell was born in St Ann's Lane, Old Pye Street, Westminster – the area of London later known as Devil's Acre, a notorious slum – in 1659. Henry Purcell Senior, whose older brother Thomas Purcell was a musician, was a gentleman of the Chapel Royal and sang at the coronation of King Charles II of England. Henry the elder had three sons: Edward, Henry and Daniel. Daniel Purcell, the youngest of the brother ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Columbia Plateau
The Columbia Plateau is a geologic and geographic region that lies across parts of the U.S. states of Washington, Oregon, and Idaho. It is a wide flood basalt plateau between the Cascade Range and the Rocky Mountains, cut through by the Columbia River. Geology During late Miocene and early Pliocene times, a flood basalt engulfed about of the Pacific Northwest, forming a large igneous province. Over a period of perhaps 10 to 15 million years, lava flow after lava flow poured out, ultimately accumulating to a thickness of more than 6,000 feet (1.8 km). As the molten rock came to the surface, the Earth's crust gradually sank into the space left by the rising lava. The Columbia River Basalt Group consists of seven formations: The Steens Basalt, Imnaha Basalt, Grande Ronde Basalt, Picture Gorge Basalt, Prineville Basalt, Wanapum Basalt, and Saddle Mountains Basalt. Many of these formations are subdivided into formal and informal members and flows. The subsidence of the crust ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pend Oreille River
The Pend Oreille River ( ) is a tributary of the Columbia River, approximately long, in northern Idaho and northeastern Washington in the United States, as well as southeastern British Columbia in Canada. In its passage through British Columbia its name is spelled Pend-d'Oreille River. It drains a scenic area of the Rocky Mountains along the U.S.-Canada border on the east side of the Columbia. The river is sometimes defined as the lower part of the Clark Fork, which rises in western Montana. The river drains an area of , mostly through the Clark Fork and its tributaries in western Montana and including a portion of the Flathead River in southeastern British Columbia. The full drainage basin of the river and its tributaries accounts for 43% of the entire Columbia River Basin above the confluence with the Columbia. The total area of the Pend Oreille basin is just under 10% of the entire Columbia Basin. Box Canyon Dam is currently underway on a multimillion-dollar project for a fi ...

Wisconsin Glaciation
The Wisconsin Glacial Episode, also called the Wisconsin glaciation, was the most recent glacial period of the North American ice sheet complex. This advance included the Cordilleran Ice Sheet, which nucleated in the northern North American Cordillera; the Innuitian ice sheet, which extended across the Canadian Arctic Archipelago; the Greenland ice sheet; and the massive Laurentide Ice Sheet, which covered the high latitudes of central and eastern North America. This advance was synchronous with global glaciation during the last glacial period, including the North American alpine glacier advance, known as the Pinedale glaciation. The Wisconsin glaciation extended from approximately 75,000 to 11,000 years ago, between the Sangamonian Stage and the current interglacial, the Holocene. The maximum ice extent occurred approximately 25,000–21,000 years ago during the last glacial maximum, also known as the ''Late Wisconsin'' in North America. This glaciation radically altered the ...

Bonners Ferry, Idaho
Bonners Ferry (Kutenai language: ʔaq̓anqmi) is the largest city and the county seat of Boundary County, Idaho, United States. The population was 2,543 at the 2010 census. History When gold was discovered in the East Kootenays of British Columbia in 1863, thousands of prospectors from all over the West surged northward over a route that became known as the Wildhorse Trail. Edwin Bonner, a merchant from Walla Walla, Washington, established a ferry in 1864 where the trail crossed the broad Kootenai River. In 1875, Richard Fry, and his Sinixt wife, Justine Su-steel Fry, leased the business, but the location retained the name of the original founder and later became the town of Bonners Ferry. Before the gold rush, only a few visitors had come to the region; one of the first was explorer David Thompson, a cartographer for the North West Company. Thompson and four fellow fur traders arrived in 1808 to trade with the Lower Kootenais. The local natives gave Thompson's party drie ...

Illinoian (stage)
The Illinoian Stage is the name used by Quaternary geologists in North America to designate the period c.191,000 to c.130,000 years ago, during the middle Pleistocene, when sediments comprising the Illinoian Glacial Lobe were deposited. It precedes the Sangamonian Stage and follows the Pre-Illinoian Stage in North America. The Illinoian Stage is defined as the period of geologic time during which the glacial tills and outwash, which comprise the bulk of the Glasford Formation, accumulated to create the Illinoian Glacial Lobe.Willman, H.B., and J.C. Frye, 1970, ''Pleistocene Stratigraphy of Illinois.'' Bulletin no. 94, Illinois State Geological Survey, Champaign, Illinois. It occurs at about the same time as the penultimate glacial period. Definition At its type exposure in Peoria County, Illinois, the Illinoian deposits consist of three till members of the Glasford Formation. They overlay Pre-Illinoian tills of the Banner Formation, in which the Yarmouth Soil (paleosol) has dev ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Kootenai River
The Kootenay or Kootenai river is a major river in the Northwest Plateau, in southeastern British Columbia, Canada, and northern Montana and Idaho in the United States. It is one of the uppermost major tributaries of the Columbia River, the largest North American river that empties into the Pacific Ocean. The Kootenay River runs from its headwaters in the Kootenay Ranges of the Canadian Rockies, flowing from British Columbia's East Kootenay region into northwestern Montana, then west into the northernmost Idaho Panhandle and returning to British Columbia in the West Kootenay region, where it joins the Columbia at Castlegar. The river is known as the Kootenay in Canada and by the Ktunaxa Nation, and Kootenai in the United States and by the Confederated Salish and Kootenai Tribes and Kootenai Tribe of Idaho. Fed mainly by glaciers and snow melt, the river drains a rugged, sparsely populated region of more than ; over 70 percent of the basin is in Canada. From its hi ...
