The Flysch Coast of Northern Spain

I was blown away by the formations on this part of the coast in Northern Spain, the Costa Verde. The enormity of how the rocks came to be like this, the strata angles and the different rocks within the layers are astounding. I was reminded of geography lessons about tectonic plates, volcanoes and could just imagine this movement happening over a matter of a day.

'The rocks, eroded by the waves and movements of the land, contain vital elements of the earth’s history. Geologists have long coveted the fossil remains for the vital clues they give to subjects such as the disappearance of the dinosaurs and global warming. The name flysch was introduced by the Swiss geologist Bernhard Studer in 1827. The name comes from the German word fliessen, which means to flow.'

'The entire area contains excellent examples of tectonic deformation structures such as different types and scales of folds and faults, which were created during the opening of the Bay of Biscay and the compression and lifting of the Pyrenees.'

Chris, the hubby, once sailed a 45ft yacht across the Bay of Biscay. Before he left he told me how the waves across the Bay are really huge because of the volume of water coming into the area from a very deep sea, suddenly has less room as the floor of the sea is much higher there from when the above compression and lifting occurred. Sure enough, he came home (safely) with tales of sailing through the night surrounded by 40 foot waves and a very scared co sailor!
