It is located east of downtown Wetumpka in Elmore County. The crater is in diameter and its age is estimated to be about 83 million years old (late Cretaceous), based on fossils found in the youngest disturbed deposits, which belong to the Mooreville Chalk Formation. The crater is well preserved, including the original impact rim and breccia, but exposures are few owing to plant and soil cover, and nearly all are on private land.〔(【引用サイトリンク】title=Wetumpka Meteor Crater )〕 Thornton L. Neathery discovered the Wetumpka Crater in 1969–70 during regional geological mapping and published the first article on the subject in 1976. However, conclusive evidence of impact origin was lacking until 1998 when David T. King, Jr. and colleagues discovered shocked quartz in a core drilled near the center of the structure. In 2002, Auburn University researchers published evidence and established the site as an internationally recognized impact crater.〔(【引用サイトリンク】 Wetumpka Impact Crater )〕〔(【引用サイトリンク】 Wetumpka Impact Crater - FAQs )〕 ==References== 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「Wetumpka crater」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
