Cratered Terrain
IMPACT FEATURES
17. Cratered Terrain (22°S,214°W)

The circular objects in this image are impact craters, formed by the collision of asteroids or comets with the surface of Mars. This heavily cratered surface is typical of the southern hemisphere of Mars. The high density of craters implies that this region is very old, probably approaching 4 billion years. This image is about 1250 kilometers across.
