Easter Island (known locally as Rapa Nui) is the original mysterious island. The islanders developed the only written language in Oceania, but the meaning of the script has been lost. The island itself is best known, of course, for its massive stone statues, or moai; how they were moved across the island remains an unanswered question. Today, the island is part of Chile and its lengthy runway doubles as an emergency landing strip for the space shuttle. But the moai remain part of the landscape - unfenced, with no markers or signs, so that walking around the island is like touring a living, open-air museum.
