Pactolus Bank or Burnham Bank was discovered at and a depth of by Captain W.D. Burnham on the American ship ''Pactolus'' on November 6, 1885. Felix Riesenberg, who served under Burnham, postulated that Pactolus Bank was the sunken location of Elizabeth Island, discovered by Sir Francis Drake's ship the ''Golden Hinde'' in 1578. Leaving the Magellan Strait, Drake's ship was driven far to the west and south, before clawing its way back towards land. On 22 October the ship anchored off an island which Drake, according to Riesenberg, named "Elizabeth Island," where wood and water was collected and seals and penguins captured for food, along with "herbs of great virtue." According to Drake's Portuguese pilot, Nuño Da Silva, their position at the anchorage was 57°S. However, no island has been confirmed at that latitude, although a sinking volcanic island may have been sighted in that vicinity by the Danish ship ''Lutterfeld'' in December 1876 or 1877. The USS Bear of Oakland investigated the area in March 1940 but her log does not mention any soundings or results. The USS ''Wyandot'' investigated the area in 1956 and found no indication of a shoal. The importance of these attempts is extremely limited, mainly due to the severe weather these ships had to operate in. So Pactolus Bank may itself be a phantom island. In 2008 Dutchman Hylke Tromp, after some years of research, published a comprehensive report, containing all known facts and myths regarding the Pactolus Bank. ==Sources== *, pp 40–45 * *, pp 77–78 * 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「Pactolus Bank」の詳細全文を読む スポンサード リンク
