Hmmm - ducks, birds? Looks like you had quite a few visitors and managed to sleep though it :) Great display of sandy texture. The little footprints look like decorations. Thanks for this fun shot Grazvydas : ^ >
I have no idea who, or what left the footprints. I am not familiar with other planets. Just Earth. Have you been on a vacation in outer space? LOL. Very nice close up of the sand and the prints.
