A flysch is a sedimentary rock formation consisting of mostly sandstones and marls near the sea and adjacent to mountains. There’s a particularly lovely one near the town of Zumaia on the northern coast of Spain.
It was formed over the past 100 million years. The sea has eroded the softer layers (clay) slower than it has the harder layers (sandstone) leaving deep ridges in the earth from the cliffs down to the water. It’s as if Slartibartfast from The Hitchhiker’s Guide to the Galaxy had dragged a giant comb through the land.

No! That could never happen! It would take much longer than 6000 years, and we *know* the Earth's only that old!
