Many theories have been advanced to explain the weird equatorial ridge girdling Iapetus. They include theories that Iapetus's ridge is an artificial phenomenon, a construct created by some technologically advanced alien civilization. But check out this photo of Iapetus's ridge taken by Cassini:
Clearly the ridge is something natural, not a wall built by advanced technosophisticates, who would have produced something much smoother, perhaps even straight-sided or crenelated, rather than Iapetus's actual ridge, the shape of which clearly shows that nothing more than gravity, centripetal force, what passes for weathering on Iapetus, tectonic processes, and/or material falling onto Iaptetus from space made the thing.
