It is a former atoll, specifically called a “Guyot”. This is an extinct volcano that has become overgrown by coral reefs to form an atoll. The flat top was once at sea level, which is why the summit is flat. It’s unmistakable shape, and it’s massive peak like that of a vast stone hat, dominates the surrounding skyline and is recognizable over a radius of thirty-five miles (56km) from nearby islands such as [[Kaibu]], [[Yacata]], and [[Vanua Balavu]].
''“The island was at one time bought and occupied by Joe Thompson, and American seaman to whose movements and affluence a great deal of mystery where attached. He seemingly had an endless supply of gold coins, the source of which he could never be induced to divulge; and as there was one part of the island which he would allow no one to approach, it was thought that he had buried the treasure there. The truth of the matter was never known. Thompson was insane at the time of his death, and the secret of his buried treasure, if it ever existed, died with him.”''
