It is located directly off Price Boulevard between US 41 and I-75 adjacent to Heron Creek Middle School in the city of North Port. On July 10, 1979, it was added to the National Register of Historic Places. ==Description== Little Salt Spring is a feature of the karst topography of Florida, specifically an example of a sinkhole. It is classified as a third magnitude spring. The numerous deep vents at the bottom of the sinkhole feed oxygen-depleted groundwater into it, producing an anoxic environment below a depth of about .〔 This fosters the preservation of Paleo-Indian and early Archaic artifacts and ecofacts, as well as fossil bones of the extinct megafauna once found in Florida.〔(【引用サイトリンク】title=Little Salt Spring Reveals More Florida History )〕 Originally it was thought that Little Salt Spring was a shallow freshwater pond, but in the 1950s SCUBA divers discovered that it was a true sinkhole extending downward over ,〔 similar to the cenotes of the Yucatán Peninsula (another karst region). The actual depth of the surface pond is forty feet with a central shaft dropping vertically to an inverted cone with a maximum determined depth at the outer edges of 245 feet. There are ledges around the wall of the cenote at 16 and below the present water level. The site has been owned by the University of Miami since 1980,〔〔 (reports the transfer date as 1982)〕 with research performed by the Rosenstiel School of Marine and Atmospheric Science. In 2013, Miami began considering selling the site to Sarasota County due to funding being cut towards maintaining the site and its facilities. 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「Little Salt Spring」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.
