<p>Sotra Facula (named after the Sotra islands in Norway) is a prominent feature on Titan, the largest moon of Saturn. It is believed to be an ice volcano or cryovolcano, forming a roughly circular mountain measuring about 65 kilometres (40 mi) across. It has two peaks standing about 1,000 metres (3,300 ft) and 1,500 metres (4,900 ft) high with multiple craters as much as 1,500 metres (4,900 ft) deep. Finger-like flows are visible on the flanks of the mountain, measuring perhaps 100 metres (330 ft) thick.
The Cassini–Huygens mission has mapped Sotra Facula using the Cassini orbiter's onboard radar instrument and the visual and infrared mapping spectrometer. An earlier survey of the region in 2004 revealed a circular bright spot, or facula, which was nicknamed "The Rose". A subsequent flyby by Cassini re-surveyed the region from a different angle, enabling members of the US Geological Survey Astrogeology Science Center to generate stereoscopic mapping of Sotra Facula and the surrounding area. Researchers also discovered at least two more mountains and another big crater, forming a chain of mountains several hundred kilometers long flanked by lava-covered lowlands.
