This image is a mosaic of Magellan data over the Lakshmi region of Venus.  The image is centered at about 66 degrees north latitude and 10 degrees east longitude.  The prominent circular feature in the image is the crater Cleopatra, located on the eastern slopes of Maxwell Montes, the highest mountain range on Venus.  Cleopatra is about 100 km (60 miles) across and 2.5 km (1.5 miles) deep.  In previous data sets, scientists were unable to determine whether Cleopatra was an impact crater or a volcanic caldera.  High-resolution Magellan data indicates that Cleopatra is a double-ring impact basin, similar to double-ring impact basins identified on the Moon, Mars and Mercury.  The inner and outer rings have a hummocky appearance typical of very large impact craters.  On the eastern edge of Cleopatra, a flow can be seen that has breached the wall of the crater and flowed downhill to surround the ridges to the east.  This flow may have been produced by melting of rocks due to the impact or by volcanism triggered by the impact.  Resolution of the Magellan data is about 120 meters (400 feet).
