Flysch K/T de Zumaya, Guipuzcoa by Eustoquio Molina
This is the longest set of continuous rock strata in the world, known locally as the "flysch;"
they date from the mid-cretaceous period to the present, a time period
of over 100 million years. The K-T boundary is present at the Itzurun
beach, and fossils can be found, notably of ammonites.
The strata stretches along a distance of about 8 km, between the
towns/beaches of Deba and Getaria, with Zumaia lying in the middle. Wikipedia
