Undersalted, Badwater Basin, Death Valley NP, California, USA
D800 with 85mm f/2.8 PC-E at f/32, 1/8 sec, ISO 100
On a whim I flipped over a chunk of salt and this is what I found. The second shot is just to give some context—miles and miles of salt and the underside probably looks like this through all of it. Pretty remarkable.
