A Land Art installation by artist V. Skip Willits of Camanche Ia and artist Mike Dodd, Southern France.
The first one is a mash up of two photos, commonly referred to as a double exposure.
The last has a ring of 53 clam shells that have holes drilled in them. When I was little, 50 years ago now, they were common along the shore of the Mississippi as remnants of the button industry that thrived before plastic. Now they show up on ocassion when a street is being repaired in the fill from 100 years ago.
