Cat Island is famous mostly for being something that it is not. For four hundred years, it was generally believed that this was the place Columbus had landed in 1492, dubbing it San Salvador. Then historians decided that—oops!—Columbus had docked somewhere else. You get the feeling that Cat Island still hasn't gotten its groove back. Being huge and underpopulated doesn't help with the identity crisis. Some two thousand people inhabit its 150 square miles—about a third of the number who work at Atlantis.
