Mount Tabor is an extinct or dormant volcanic vent, the city park on the volcano, and the neighborhood of Southeast Portland that surrounds it, all in Oregon. The name refers to Mount Tabor, Israel, part of Portland's distinct Jewish culture and past. 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: Rocky Butte, Powell Butte, and Kelly Butte. Portland is one of four cities in the United States to have an extinct volcano (Mount Tabor) within its boundaries. Bend is the only other city in Oregon with a volcano within its city limits, with Pilot Butte.〔(【引用サイトリンク】 Guide to the Mount Tabor Neighborhood )〕 Jackson Volcano in Jackson, Mississippi and Diamond Head in Honolulu being the others. The volcanic nature of Mount Tabor became known in 1912, years after reservoirs and a public park were developed on it. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Mount Tabor (Oregon)」の詳細全文を読む スポンサード リンク
