A forest on a rock

A few tens of metres away from home there's a green patch with a big rock. Since we moved here my children named it the 'big stone' and they love to go there. The youngest inherited their passion and the big stone is the place he is always asking to go. So the other day while he was climbing I decided to give a closer look at the moss that covers most part of the stone in this period of the year. Well, moss is one of the most fascinating things in nature, so many different kind, different colors, different look, just like in a full sized forest, with its variety of trees and plants.
