A report on Cryovolcano and Sotra Patera

Doom Mons, one of the most reliably identified cryovolcanoes on Saturn's moon Titan

Stereoscopic map of Sotra Patera and Doom Mons. Height is exaggerated by a factor of 10. The colours are false.

Plumes of Enceladus, feeding Saturn's E Ring, seem to arise from the "Tiger Stripes" near the south pole.

Global view of Titan showing the location of Sotra Patera

It is a possible cryovolcanic caldera 30 km across and 1.7 km deep, and is immediately to the east of the largest putative cryovolcanic mountain on Titan, the 1.45 km high Doom Mons.

- Sotra Patera

Cassini has observed several features thought to be cryovolcanoes on Titan, notably Doom Mons with adjacent Sotra Patera, a feature regarded as "the very best evidence, by far, for volcanic topography anywhere documented on an icy satellite."

The geologically young surface is generally smooth, with few impact craters, although mountains and several possible cryovolcanoes have been found.

Named Sotra Patera, it is one in a chain of at least three mountains, each between 1000 and 1500 m in height, several of which are topped by large craters.

Name of a mountain range and its eponymous peak on Titan, the largest moon of Saturn.

A putative cryovolcano, it is the largest mountain range on Titan by volume, and at 4757 ft one of the highest in the Solar System.

It is located within the Aztlan darklands region, possibly connected to the wider Shangri-La dark region, and is adjacent to Sotra Patera, a possible cryovolcanic caldera 1.7 km deep.
