Recently released images taken by the Mars Global Surveyor show the dynamic Martian terrain is anything but dull. Although the Martian northern plains are often considered to be “flat” or “featureless,” the MOC has shown that, at the scale of a few tens of meters (tens of yards), these plains aren’t at all “boring”. In the October 2001 MOC image shown at right, a suite of sharply-outlined pits and fractures indicate that the upper surface materials are strong and indurated (cemented).
