The estimated age of Fuerteventura as an island is some 18-20 million years. The earliest formation is thought to be Tindaya, reckoned by its material which differs significantly from that of the rest of the island. The mountain Tindaya is a large lump of Trachite, whereas the Betancuria massif is Basalt based. One million years is along time and although not populated by humans, Fuerteventura was the home to many species of plants and animals that we will never guess how they looked or grew. However, there is one instant that has left its traces.
