Last week i've received an envelope from Déa, my dear brazilian friend. She sent me 3 cards and one of them was this one showing a grotto in the rock, on the southeast coast of Marion Island, South Africa.
Marion Island is one of the two islands of the Prince Edward Islands. They are two small islands in the sub-antarctic Indian Ocean that are part of South Africa.
The islands in the group have been declared Special Nature Reserves under the South African Environmental Management and activities on the islands are therefore restricted to research and conservation management. The only human inhabitants of the islands are the staff of a meteorological and biological research station run by the South African National Antarctic Programme on Marion Island. - in: wikipedia
