The "Cat Scratches"

Original caption:"The geologic diversity of Titan's surface is well illustrated by this synthetic aperture radar image, obtained on Oct. 28, 2005, during the Cassini spacecraft's 9th Titan fly-by and 4th radar pass.
The bottom left and top right parts of the image show a series of parallel features resembling those discovered during the second radar pass. Called "cat scratches", these features may be dunes of water ice or hydrocarbon particles. The brighter area on the bottom right is thought to be rougher and possibly higher in elevation than the darker areas. Above the center of the image are dark, narrow winding channels carved by, and possibly still containing, liquids.

This image is about 300 by 250 Km and it is located 10° South Lat. and 292° West Long.".
