The Strangles cliff

Originally uploaded as a clue to a Guesswhere UK photo.
This is a view of the upper cliff overlooking The Strangles, near Crackington Haven, north Cornwall. The cliff is comprised of the Crackington Formation: upper Carboniferous turbidites and shales, which have been subjected to intense folding and a near-horizontal axial-planar, slaty cleavage is well developed in the shaly parts of the sequence, as in this location. The cliff has been extensively quarried in the past for slates.
