No, this is not in fact a photo taken by mistake, but a close up study of some of the local flora. The picture doesn't really do it justice but the colour of this lichen was quite striking, almost luminescent. I say "flora" but lichen is not in fact just your average plant, but a symbiotic organism consisting of a fungus with a photosynthetic alga. I can assure you, there's some pretty cool stuff going on on this here rock.
