The mountains probably formed when material welled up from below to fill the gaps opened when tectonic plates pull apart, similar to the way mid-ocean ridges are formed on Earth.
The evidence is mounting that this circular feature is a volcano,” said Dr. Rosaly Lopes, Cassini radar team member at NASA’s Jet Propulsion Laboratory, Pasadena, Calif. “With radar data alone, we identified it as a possible volcano, but the combination of radar and infrared makes it much clearer.”
The dunes seem to consist of sand grains made of organics, built on water-ice bedrock, and there may also be some snow and bright deposits," Brown said.
Some of this organic gunk falls out of the atmosphere as rain, dust, or smog onto the valley floors and mountain tops, which are coated with dark spots that appear to be brushed, washed, scoured and moved around the surface.",
mountains composed of ice, covered with black snow from tarry substances and covered from methane clouds,
what a strange world!
