Unexpected belt of ice on Titan Options

[MarcF]

A massive belt of water ice, 6,300 kilometers long, has been identified on the surface of Titan.

“It’s possible that we are seeing something that’s a vestige of a time when Titan was quite different,” says Griffith. “It can’t be explained by what we see there now.” Titan is probably not geologically active now, but the exposed ice could be a sign of the moon’s crust shifting or quaking in the past.
The ice may be embedded in the side of cliff faces exposed by erosion, rather than flat on the ground, Griffith says"

The water ice feature localizes to the huge linear formation including the Aztlan sand sea and its extensions on each side, which is probably not a coincidence. It reminds me the complex ridge-trough system at least 3200 km long extending north-to-south along the 155° meridian on Pluto.
