Mount Scott is a small stratovolcano and a so-called ''parasitic cone'' on the southeast flank of Crater Lake in southern Oregon. It is approximately 420,000 years old.〔 Its summit is the highest point within Crater Lake National Park, and the tenth highest peak in the Oregon Cascades.〔 〕 A small fire lookout tower stands on the summit, at the end of a trail that zigzags approximately 1,500 feet (460 m) up the mountain. The mountain is named for Oregon pioneer Levi Scott, founder of Scottsburg, Oregon.〔 〕 ==Geology== Mount Scott first erupted about 420,000 years ago and is one of the oldest volcanoes in the Mount Mazama complex.〔 〕〔 〕 It erupted mainly andesitic lavas before becoming extinct in the late Pleistocene.〔 〕 Since it was relatively far away from the main flanks of Mount Mazama, it survived the mountain's massive explosion that occurred around 5700 BC.〔 〕 Currently at tall, Mount Scott is the highest point in Crater Lake National Park.〔〔 (【引用サイトリンク】 Crater Lake National Park )〕〔 (【引用サイトリンク】 Crater Lake, Oregon )〕〔 〕〔 〕〔 〕 Most of the lower slopes are covered with ash, pumice, and loose gravel, while the summit is mostly covered with scoria.〔〔 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 Scott (Klamath County, Oregon)」の詳細全文を読む スポンサード リンク
