Living rocks – you can take that term any way you like!
If “living rocks” refers to rocks living, then I guess evolving might be a better term in that they are changing over time albeit slowly. But as an environment for growth there can be no question that one aspect of these rocks is definitely living and that is the beautiful, colourful, hairy and blistery lichens that grow on their surface.
Whether growth on the surface or the evolution of pattern through erosion, the rocky surroundings on some of my walks while away in Scotland just blew my mind . . . so to speak. I know them well but never grow tired of them and it feels as though every visit reveals something new, even though the last thing these rocks and lichens are is new.
