Nimrod Island
The yacht was the world-girdling Awahnee, the first ferro-cement vessel to circumnavigate, now carrying her owners, Dr. Robert Lyle Griffith, his wife, Nancy, and son, Reid, on their third circumnaviga- tion of the world, this time on a track never before attempted by a pleasure craft.
Four days out of Campbell Island, they lost a headstay and repairs were made by agile Reid. At 63°S, they were trapped by ice and had to backtrack for 40 miles. On the tenth day, at 61°S and 159°W, they sighted three islands where no land was shown on the charts.(4)
4. The nearest charted land was the Nimrod Island group, three hundred miles to the north. The U.S. Hydrographic Office reported the islands were discovered in 1828 and not sighted again. In 195t, they were removed from all charts as nonexistent. The Griffiths applied to have them named the Awahnee Islands.

Several phantom islands were once charted in the area four hundred to five hundred miles south of Tasmania. One group, the Royal Company Islands, were eliminated from charts in 1904. In this same area, Nimrod Island was discovered in 1828 by Captain Eilbech and named after his ship. Five years later Captain John Biscoe found marine vegetation and numerous birds at the location given, but no islands. Two antarctic explorers, Shackleton in 1909 and Scott in 1913, made unsuccessful searches, and soundings disclosed a two mile depth. Nimrod was dropped from charts in 1922.
