Victoria Crater, Mars (2008)

"Victoria crater" is an impact crater near the equator of Mars, in the "Meridiani Planum". The crater is approximately 800 meters (about half a mile) in diameter. The rough edges indicate erosion, and layered sedimentary rocks are exposed along the edge. The ripples in the bottom of the crater are wind-blown sand dunes.
