I call this photo “Life on Mars”. I took this with a drone over the Christmas Valley Sand Dunes in central Oregon. This was right as the sun was setting in the high desert and I love how the shadow of this massive sand dune jumps out as the sun slips under the horizon. These sand dunes are pretty remote but worth the trip if you don't mind a long drive and unpaved roads. You can drive right up on the sand dunes if you have all-wheel drive.
