Mars - Viking 2 Orbiter
Viking image of the Inca City feature on Mars
Viking 2 Orbiter image of an area near the south pole of Mars given
the name Inca City. This semi-rectangular grid (at center-right)
is probably the result of wind deflation of deposits revealing the
underlying gridded terrain. The individual square cells are about
4 to 5 km across. An ice deposit can be seen at the upper left of
the frame, which is to the south. North is at 4:00.
