Hamelin Pool Stromatolites |

Stromatolites are the oldest living organisms on the planet. The water of Hamelin Bay is Twice as salty as normal sea water because there is a sand bar across the bay's entrance and the rapid evaporation from the shallow water. |

Most living animals which feed on the bacteria and algae of which Stromatolites are composed , cannot tolerate such salty conditions, so they can grow here undisturbed. |

The viewing platform takes you out over the water and there are little boards like this telling you the story of the Stromatolites. I thought the EIP was cute. |
