Meridiani Craters

This image is from the Meridiani region of Mars. Several craters at different stages of modification are visible in this image. At the upper right is a crater with its rim forming a thin circular ridge surrounding a filled crater floor. Diagonally down from the first crater is a circular feature which may be a completely filled crater. On the left side is a crater with visible ejecta and a partially filled floor. The rim interior wall is almost completely exposed on this crater.
