An overhead color view of the Martian surface shows rough and varied terrain in shades ranging from golden tan to electric blue. At upper left, the ground appears more flat and cratered than other areas of the image, and is colored dark grayish-blue with highlights of silver and tan. The upper right corner of the image looks like wavy sand dunes, in shades of dark blue with bright silvery highlights, except for one apparent ridgeline that stands out as an elongated S-shape in electric blue. The bottom half of the image shows more mountainous terrain that gets lighter and more gold-colored nearer the bottom of the frame. A pair of smooth valleys run diagonally between the peaks, from around the center of the image toward the bottom-left corner; the upper one is a shade of silvery blue and the bottom one is a grayish-gold, and both have ridges lining their upper walls, looking like lines of sharp teeth biting into the valleys.
