The Grooved Terrain of Ganymede
This image shows an example of the grooved terrain of Ganymede.
The image clearly shows that some things hit Ganymede and made craters after the grooves were created, because the grooves are underneath the craters.
A closeup view of these grooves, provided by the Galileo spacecraft, reveals that the ridges are actually many ridges which have mysteriously been pulled apart.
