Titanic Deluge (IMAGE) University of Arizona Caption Titanic Deluge: The storm created large effects in the form of dark -- likely wet -- areas on the surface of the moon. After it dissipated, Cassini observed significant changes on Titan's surface at the southern boundary of the dune field named Belet. Those changes covered an area of roughly Arizona and Utah. Scientists interpret the changes seen in these images (blue outlines) to be evidence of methane rain wetting the surface.
