Proctor Crater that has both dunes and ripples
Légende
This image shows an area within Proctor Crater that has both dunes and ripples. The smaller, brighter ridges are ripples made of very fine sand. The larger, darker forms are dunes made of dust from dark volcanic rocks. This image was taken by the High Resolution Imaging Science Experiment (HI RISE) camera on NASA’s Mars Reconnaissance Orbiter in February 2009.
