Vid Flumina

Vid Flumina is a river system (termed Flumen) of liquid methane and ethane on Saturn's moon Titan.

The scientists at NASA were expecting to find some evidence for liquid methane because of Titan's surface temperature and its methane-rich atmosphere.

[3] The early disappointment changed as the Cassini's orbit shifted and allowed the researchers at NASA to bounce radar off other regions of the moon.

[5][6] The river slices through a rough and slanted terrain, which suggests operation of processes similar to tectonic movements on Earth.

The canyons are thought to have formed by erosion stimulated either by uplift of the area or a decline in the level of Ligeia Mare.
