This picture merely shows the amount of mystery that the island has to offer. Erosion has covered the moais so we can only see their heads, this is just a parodied image to illustrate the conundrums of Rapa Nui.
For "us", the foreigners.. it is Easter Island or Isla de Pascua. However for the natives, it is Rapa Nui which means the "land's end" or the "navel of the world".
It is a unique culture in the world; a week of getting to live with such a lifestyle makes you realize many things...
