If this lichen could talk! The stories it could tell. Lichen grows very slowly. Usually an average of 1 mm/year or .0393701 inches/year. Although you have no sense of scale as to how big this rock is, take my word for it, it is boulder-sized. I'm guessing 3 1/2 feet. I was taken by how intensely covered this rock was that it reminded me of a frosted cupcake.
I am celebrating the mundane!
