The
high resolution of 600 meters reveals a bewildering variety of fractures,
grooves and craters, as well as features of different albedos (reflectancea).
This clear-filter, narrow-angle view encompasses areas of older, heavily
cratered terrain with a wide variety of forms. The grooves and troughs reach
depths of a few kilometers and expose materials of different albedos. |

The
great variety of directions of fractures and troughs, and the different
densities of impact craters on them, signify a long, complex geologic evolution
of this satellite. |
