A 1937 report by Navy flyers spoke of signs of "recent habitation" on the island. Salvaged airplane parts have been found there. An American-style woman's shoe, consistent with ones Earhart wore, was discoverd during a 1991 TIGHAR expedition. Evidence of a campfire was found in 1997, consistent with reports that near the camp site, a bottle, a can and human bones were found. A doctor's 1941 analysis concluded those since-lost bones were from a man, but an expert told TIGHAR the measurements were more consistent with a woman.
