Lake Allison
Lake Allison was a temporary lake in the Willamette Valley of Oregon, formed periodically by the Missoula Floods from 15,000 to 13,000 BC. The lake is the main cause of the rich and fertile soil that now characterizes the Willamette Valley. History Willamette Valley fertility, like the Palouse silt, is in large part due to the largest freshwater flood scientifically documented in history. The ice floods started in Lake Missoula in Montana 12,000 to 15,000 years ago during the Pleistocene and flowed down through eastern Washington, bringing fertile soil to the valley as it flowed out the Columbia River Gorge. The narrows at Kalama, Washington, restricted the flow of water, causing it to back up and flood the Willamette Valley to a depth of above sea level as far south as Eugene.''Cataclysms on the Columbia'', by John Elliott Allen and Marjorie Burns with Sam C. Sargent, 1986. Pages 175–189. The Willamette Valley had multiple floods during the last ice age, possibly reaching 100 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Glacial Lake Missoula
Lake Missoula was a prehistoric proglacial lake in western Montana that existed periodically at the end of the last ice age between 15,000 and 13,000 years ago. The lake measured about and contained about of water, half the volume of Lake Michigan. The ''Glacial Lake Missoula National Natural Landmark'' is located about 110 kilometres (68 mi) northwest of Missoula, Montana, at the north end of the Camas Prairie Valley, just east of Montana Highway 382 and Macfarlane Ranch. It was designated as a National Natural Landmark in 1966 because it contains the great ripples (often measuring high and long) that served as a strong supporting element for J Harlen Bretz's contention that Washington State's Channeled Scablands were formed by repeated cataclysmic floods over only about 2,000 years, rather than through the millions of years of erosion that had been previously assumed. The lake was the result of an ice dam on the Clark Fork caused by the southern encroachment of a f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mount Tabor (Oregon)
Mount Tabor is an extinct volcanic vent with a city park on the volcano, located in Portland, Oregon's neighborhood of the same name. The name refers to Mount Tabor, Israel. It was named by Plympton Kelly, son of Oregon City pioneer resident Clinton Kelly. Cinder cone The peak of Mount Tabor is in elevation; about two-thirds of this is prominence since the surrounding land is about elevation. Near the peak, where a basketball court and outdoor amphitheater are now situated, part of the cinder cone has been cut away, and the rock is visible to park visitors. The remaining cinders were used to pave the nearby parking lot. The Tabor cinder cone is part of the Boring Lava Field, an extensive network of cinder cones and small shield volcanoes ranging from Boring, Oregon, to southwest Washington, and dating to the Plio-Pleistocene era. The lava field has been extinct for over 300,000 years. Three other cinder cones from this field also lie within the city of Portland: ...
