<ul><li><b>Scope and content:</b>  This false-color view of the volcano Sif Mons on Venus was made by superposing Magellan radar image data on altimetry data. The volcano is 2.0 kilometers (1.2 mile) high and 300 kilometers (180 miles) in diameter. Sif Mons is located on the broad 2300 kilometers x 2000 kilometers (1380 x 1200 miles) rise of Western Eistla Regio, a region that may have formed from the upwelling of hot material from the interior of the planet.</li></ul></div>
