Lake Coeur D'Alene
Lake Coeur d'Alene, officially Coeur d'Alene Lake ( ), is a natural dam-controlled lake in North Idaho, located in the Pacific Northwest region of the United States. At its northern end is the city of Coeur d'Alene. It spans in length and ranges from 1 to wide with over of shoreline. The lake was named after the Coeur d'Alene people. Geology and geography Lake Coeur d'Alene, like other lakes surrounding the Spokane Valley and Rathdrum Prairie, was formed by the Missoula Floods, most recently 12,000 to 15,000 years ago. The Purcell Lobe of the Cordilleran Ice Sheet flowed south from Canada, carving the basin of present-day Lake Pend Oreille and damming the Clark Fork river. The impounded river repeatedly filled to form Glacial Lake Missoula and broke through the ice dam, resulting in massive floods that filled the Rathdrum Prairie area with sand, gravel, and boulders. Large eddy bars formed downstream from bedrock obstructions, thereby damming tributary valleys and creati ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kootenai County, Idaho
Kootenai County ( ) is located in the U.S. state of Idaho. In 2020, the United States Census Bureau estimated the county's population at 171,362, making it the third-most populous county in Idaho and by far the largest in North Idaho, the county accounting for 45.4% of the region's total population. The county seat and largest city is Coeur d'Alene. The county was established in 1864 and named after the Kootenai tribe. Kootenai County is coterminous with the Coeur d'Alene metropolitan area, which along with the Spokane metropolitan area comprises the Spokane–Coeur d'Alene combined statistical area. History Natives and early European activity The Coeur d'Alene region takes its name from that given the local natives by French fur trappers. The tribe initially consisted of three bands that inhabited the areas surrounding Coeur d'Alene Lake and the Coeur d'Alene River. Canadian fur trade came to the region starting in 1809, marking the tribe's first contact with Europeans. Ch ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Steam Navigation On Lake Coeur D'Alene
Steam navigation on Lake Coeur d'Alene lasted from the 1880s to the 1930s. More steamboats operated on Lake Coeur d’Alene than on any other lake west of the Great Lakes. The high point of steam navigation was probably from 1908 to 1913. After that railroads, and increasingly automobile and truck traffic on newly built highways supplanted steam navigation, although some vessels continued to be operated until the mid-1930s. Operations In September 1908, the Red Collar steamship line operated seven steamers on Lake Coeur d'Alene, which was 27 miles, running mainly in a north-south direction. The main city on the lake was Coeur d’Alene, at the northern, downstream end. By 1908 the city of Coeur d'Alene was connected by steam and electric rail lines to Spokane, Washington, about 30 miles to the west. The lake varied from 50 to 400 feet deep, and with the adjacent navigable St. Joe River, formed a natural water route just over 60 miles long. In the summer months, in 1908, th ...

Ford Model T
The Ford Model T is an automobile that was produced by Ford Motor Company from October 1, 1908, to May 26, 1927. It is generally regarded as the first affordable automobile, which made car travel available to middle-class Americans. The relatively low price was partly the result of Ford's efficient fabrication, including assembly line production instead of individual handcrafting. It was mainly designed by an American ( Childe Harold Wills) and two Hungarian engineers ( Joseph A. Galamb, Eugene Farkas). The Model T was colloquially known as the "Tin Lizzie", "Leaping Lena" or "flivver". The Ford Model T was named the most influential car of the 20th century in the 1999 Car of the Century competition, ahead of the BMC Mini, Citroën DS, and Volkswagen Beetle. Ford's Model T was successful not only because it provided inexpensive transportation on a massive scale, but also because the car signified innovation for the rising middle class and became a powerful symbol of the U ...

Harrison, Idaho
Harrison is a city in Kootenai County, Idaho, United States. The population was 203 at the 2010 census. Harrison is located on the eastern shore of Lake Coeur d'Alene, immediately south of where the Coeur d'Alene River flows into the lake. History The community was named for President Benjamin Harrison. Harrison was incorporated in 1899 and was once the largest city on Lake Coeur d'Alene. Harrison developed from a squatters homestead to a thriving village in about twelve years. A branch of the O.R. & N. Railroad from Tekoa, Washington, to Harrison was completed in 1890 and was a prime factor in the development of Harrison. In 1891, Silas W. Crane settled on a timbered tract which joins the present city on the south and east. He built the first house in Harrison which remained in the Crane family until 1936. The building is now used as the Crane House Museum. The same year Fred Grant purchased the Fisher Brothers Sawmill in St. Maries and moved it to Harrison. Known as Grant ...

David Thompson (explorer)
David Thompson (30 April 1770 – 10 February 1857) was a English Canadian, British-Canadian fur trader, surveying, surveyor, and Cartography, cartographer, known to some native people as "Koo-Koo-Sint" or "the Stargazer". Over Thompson's career, he travelled across North America, mapping of North America along the way. For this historic feat, Thompson has been described as the "greatest practical land geographer that the world has produced". Early life David Thompson was born in Westminster, Middlesex, to recent Welsh migrants David and Ann Thompson. When Thompson was two, his father died. Due to the financial hardship with his mother without resources, Thompson, 29 April 1777, the day before his seventh birthday, and his older brother were placed in the Grey Coat Hospital, a school for the disadvantaged of Westminster. Thompson graduated to the Grey Coat mathematical school, well known for teaching navigation and surveying. He received an education for the Royal Navy: inclu ...

AMSL
Height above mean sea level is a measure of the vertical distance (height, elevation or altitude) of a location in reference to a historic mean sea level taken as a vertical datum. In geodesy, it is formalized as ''orthometric heights''. The combination of unit of measurement and the physical quantity (height) is called "metres above mean sea level" in the metric system, while in United States customary and imperial units it would be called "feet above mean sea level". Mean sea levels are affected by climate change and other factors and change over time. For this and other reasons, recorded measurements of elevation above sea level at a reference time in history might differ from the actual elevation of a given location over sea level at a given moment. Uses Metres above sea level is the standard measurement of the elevation or altitude of: * Geographic locations such as towns, mountains and other landmarks. * The top of buildings and other structures. * Flying objects such ...

Tributary
A tributary, or affluent, is a stream or river that flows into a larger stream or main stem (or parent) river or a lake. A tributary does not flow directly into a sea or ocean. Tributaries and the main stem river drain the surrounding drainage basin of its surface water and groundwater, leading the water out into an ocean. The Irtysh is a chief tributary of the Ob river and is also the longest tributary river in the world with a length of . The Madeira River is the largest tributary river by volume in the world with an average discharge of . A confluence, where two or more bodies of water meet, usually refers to the joining of tributaries. The opposite to a tributary is a distributary, a river or stream that branches off from and flows away from the main stream. PhysicalGeography.net, Michael Pidwirny & S ...

Bar (river Morphology)
A bar in a river is an elevated region of sediment (such as sand or gravel) that has been deposited by the flow. Types of bars include mid-channel bars (also called braid bars and common in braided rivers), point bars (common in meandering rivers), and mouth bars (common in river deltas). The locations of bars are determined by the geometry of the river and the flow through it. Bars reflect sediment supply conditions, and can show where sediment supply rate is greater than the transport capacity. A mid-channel bar, is also often referred to as a braid bar because they are often found in braided river channels. Braided river channels are broad and shallow and found in areas where sediment is easily eroded like at a glacial outwash, or at a mountain front with high sediment loads. These types of river systems are associated with high slope, sediment supply, stream power, shear stress, and bed load transport rates. Braided rivers have complex and unpredictable channel patt ...

Eddy (fluid Dynamics)
In fluid dynamics, an eddy is the swirling of a fluid and the reverse current created when the fluid is in a turbulent flow regime. The moving fluid creates a space devoid of downstream-flowing fluid on the downstream side of the object. Fluid behind the obstacle flows into the void creating a swirl of fluid on each edge of the obstacle, followed by a short reverse flow of fluid behind the obstacle flowing upstream, toward the back of the obstacle. This phenomenon is naturally observed behind large emergent rocks in swift-flowing rivers. An eddy is a movement of fluid that deviates from the general flow of the fluid. An example for an eddy is a vortex which produces such deviation. However, there are other types of eddies that are not simple vortices. For example, a Rossby wave is an eddy which is an undulation that is a deviation from mean flow, but doesn't have the local closed streamlines of a vortex. Swirl and eddies in engineering The propensity of a fluid to swirl is used ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
