We went camping on the coast last week. A walk along the beach was filled with fascinating artifacts–not just fossils and seashells, but also faces . . .
. . . art on the sandstone bluffs!
Some were naturally formed.
Some were less than eloquent and original.
Some told a story (we had fun with storylines for this one, located about 60 feet straight up the cliff, via a very steep sand dune)
Some were simply clever and entertaining.
Sure, most of them were technically illegal–defacement of a natural feature? But unlike road-building or commercial development, etc, none caused any real or lasting harm, and they carry forward an ancient tradition of self expression and creation of art from the earliest days of humankind.
