Regional parallel curved lines

[xoldogx]

This is a older picture from Olympus Mons Caldera from Marsexpress from 2004.
There is not much detail visible, but the one who zoom in will notice
lots of parallel curving lines, change the contrast and lightning a little bit and you maybe will see it clearer. Could be only a natural feature, someone else has a idea about the origin of this geographical feature ?
