At Torrisdale Bay on the Eastern Cost of Kintyre is this extraordinary rock formation, formed I assume as molten lava reached the sea! However, information regarding these rocks appears to be non-existent.
PIP included for a cross view !

The sea is the Kilbrannan Sound with the Isle of Arran in the far distance

I will also say that in the main image, the light/Lens combination has turned the rock slightly greener than I remember it!

It only really becomes clear in a large view !!!!!!
