About this image

This VIS image shows part of Olympia Undae, a vast sand sea near the north pole. In regions with limited sand abundance, individual dunes form and the surface below the dunes are visible. This is the case at the top of the image. When sand abundances grow, the individual dunes coalesce into a sheet of sand hiding the underlaying surface. This is the case at the bottom of the image.
