Skeleton Cave is a lava tube within Deschutes County, Oregon, of the United States. The cave is within Deschutes National Forest and is located on the northern flank of Newberry Volcano near the city of Bend. == Origin of the name == The cave was discovered in about 1924 although a stick was found inside the cave with penciled markings showing visitation from 1894. Perhaps on that same visit, an illegal moonshiner's still was found inside the cave.〔 〕〔 〕 At one time the lava tube may have been referred to as Bone Cave〔 but it received its current moniker as Skeleton Cave from Phil Brogan who observed many assorted pieces of skeletons within.〔 The skylight entrance to the cave served as a natural trap in which animals could not escape. Several newspaper accounts note fossils within. The most noteworthy remnants belonged to a horse from the Pleistocene that was later identified as ''Equus niobrarensis''.〔 〕〔 〕 Many other pieces of bone were found inside the cave. A list of the known skeletal pieces include:〔 〕〔 〕〔 〕〔 〕〔 〕〔 〕 〔 〕 * Bear * Horse * Deer * Elk * Alopex Fox or Arctic Fox * Gray Fox * Wolf (nearly as large as ''Canis occidentalis'') * a small carnivore the size of a martin * Rodents * Lynx * A large hyena-like dog 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「Skeleton Cave」の詳細全文を読む スポンサード リンク
