Idunn Mons (Perspective View and False Colors; credits: NASA/JPL-Caltech/ESA)

Caption NASA:"This figure shows the Volcanic Peak Idunn Mons (at about 46° South Lat. and 214,5° East Long.) in the Imdr Regio area of Venus. The topographic backbone derives from data obtained by NASA's Magellan spacecraft, with a vertical exaggeration of 30 times.
Radar data (in brown) from Magellan has been draped on top of the topographic data. Bright areas are rough or have steep slopes. Dark areas are smooth.
The warmest area of Idunn is centered on the Summit, which stands about 2,5 Km (approx. 1,6 miles) above the Datum, and the bright Lava Flows that originate there. Idunn Mons has a diameter of about 200 Km (approx. 120 miles).

The spectrometer data was collected from May 2006 to the end of 2007. A movie featuring 360-degree views of the volcano is based on the same data and can be viewed at JPL's Multimedia".
