Canyonland on Titan

Fluids have flowed and cut these deeply-incised channels into the icy surface of Titan as seen in this SAR image. The channels are roughly 1 Km across (about 0,6 miles) and perhaps 200 mt deep (about 650 feet); some can be traced as far as 200 Km (about 120 miles). Many of them have angular segments suggesting they may follow faults in Titan's crust.
Taken together with the two other radar passes (October 2004 and February 2005), these very HR images have identified at least two distinct types of drainage and channel formation on Titan. The style shown in this image consists of long valleys following angular patterns without many tributaries, suggesting that fluids flow over great distances.
This Cassini radar image was acquired as a part of the Titan flyby observations taken on Sept. 7, 2005, from a distance of about 2000 Km. The area is located at about 55° South Latitude, 7,5° West Longitude and extends over 300 km (about 186 miles) right to left.
