Topgallant Islands is an island group located in the Investigator Group about south west of Cape Finniss on the west coast of Eyre Peninsula in South Australia. The group was discovered and named by Matthew Flinders on 13 February 1802. The island group has enjoyed protected area status since the 1960s and since 2011, it has been part of the Investigator Group Wilderness Protection Area. ==Description== Topgallant Islands is an island group located about south west of Cape Finniss on the west coast of Eyre Peninsula in South Australia, about west by south of the town of Elliston and about east of Flinders Island.〔DMH, 1985, chart 38〕〔〔 The group consists of an islet and a number of bare rocks which are numbered at seven in one source and which extend from the islet in a line for a distance of about to the south east. The islet which has an area of about , is encircled by high cliffs and has a rounded top whose summit is at above sea level. The southernmost rock is reported as being a ‘sharp pyramid’ of height.〔〔〔Robinson, 1996, page 481〕 The name used for the island group varies from the name given by Flinders (i.e. Topgallant Isles) as follows: Topgallant Islands, Top-gallant Islands, Top-Gallant Isles and Top Gallant Isles.〔〔〔〔Robinson et al, 1996, page 193〕〔 Access to Topgallant Island by boat is reported as not being possible due to a ‘combination of deep water swells, steep shores and sheer walls of rotten stone’. A survey carried in 1980 used a helicopter to land personnel on the islet.〔Robinson et al, 1996, page 194〕〔Robinson et al, 1996, pages 382, 388 & 390〕 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「Topgallant Islands」の詳細全文を読む スポンサード リンク
