The boundary of the bright (rough) region and the dark (smooth) region appears to be a shoreline. The patterns in the dark area indicate that it may once have been flooded, with the liquid having at least partially receded.

The image is 175 kilometres high and 330 kilometres wide, and is located at 66 degrees South, 356 degrees West in the southern hemisphere of Titan. The Cassini-Huygens mission is a cooperative project of NASA, the European

Fluids have flowed and cut these deeply incised channels into the icy surface of Titan. The channels are roughly 1 kilometre across and perhaps 200 metres deep; some can be traced back as far as 200 kilometres. Many of them have angular segments suggesting they may follow faults in Titan's crust. .

In contrast to the image of the 'canyonlands' of Titan, this bright terrain is cut by channels that are variable in width; they form both radial and branching networks. Such patterns are reminiscent of networks formed by rainfall on Earth.

At the bottom of the frame, the channels radiate from a possible source into a dark, smooth region that seems flatter and more plain-like. One interpretation is that the higher, rougher terrain has been cleansed of organic debris and eroded by methane rainfall. The removed material has then been deposited into the lower plains.
