About this work
This VIS image of Olympia Undae was collected in the middle of north polar spring. As the season changes into summertime, the dune crests will lose all the winter frosts, completely revealing the darker sand beneath. The density of dunes and the alignments of the dune crests varies with location, controlled by the amount of available sand and the predominant winds over time. Olympia Undae is a vast dune field in the north polar region of Mars.
