Possible Tectonic fractures on Titan

Original caption:"This synthetic aperture radar image of Titan was taken on Oct. 28, 2005, as the Cassini spacecraft flew by at a distance of 1.350 Km (about 840 miles). This was the first pass dedicated to radar and it was the fourth time Cassini's radar honed in on the smoggy moon.
The bright, curving features are high-standing ridges, poking up above the plains of Titan. Some of the ridges extend for over 100 Km (roughly 60 miles). They are likely to be tectonic in origin, formed by deformation of Titan's icy crust. The low-lying terrain between the ridges is covered in dark streaks, which could be dunes formed by wind. The streaks, spaced 1 to 2 Km apart (0,6 to 1 mile), curve between patches of the bright terrain, which probably act as topographic barriers.
This image is 400 Km (about 250 miles) across and 275 Km-wide (about 170 miles). It is located 8° South Latitude and 215° West Longitude".
