Geopark of the Basque Coast: the Earth's history book

On Spain's northern coast, in the stretch that runs between Biscay and the Basque Mountains that straddle the border with France, people from all over the world visit the Euskal Kostaldea Geopark, attracted by a stunning landscape that features a rare geological formation known as a flysch. A flysch is a sequence of sedimentary rock layers in which soft shale beds alternate with harder sandstone, creating a pattern that is not only visually very appealing, but possesses immense scientific value. "The history of the Earth is written on the planet's rocks," the geopark's scientific director, Asier Hilario, explained in an interview with EFE.
