This interesting pattern of circles makes us wish for a honey-baked ham to pair with this swiss cheese. These circles, found in the south polar region of Mars, are probably formed by melting carbon dioxide ice. Some of the mesas inside the circles could be 13 feet high and as large as a small town.
