A portion of the eastern edge of Alpha Regio is displayed in this three-dimensional perspective view of the surface of Venus. The view is to the northeast at the center of an area containing seven circular dome-like hills. The average diameter of the hills is 25 kilometers (15 miles) with maximum heights of 750 meters (2,475 feet). Three of the hills are visible in the center of the image. Fractures on the surrounding plains are both older and younger than the domes. The hills may be the result of viscous or thick eruptions of lava coming from a vent on the relatively level ground, allowing the
This image is a computer generated, 3-dimensional perspective view of the "crater farm" on Venus.  Saskia, a crater 37.3 km in diameter, is in the foreground.  Danilova, 47.6 km in diameter, is on the left, and Aglaonice, 62.7 km in diameter, is to the right.  The image was created from Magellan images with colors based on the Soviet Venera 13 and 14 Lander images.

lava to flow in an even lateral pattern. The concentric and radial fracture patterns on their surfaces suggests that a chilled outer layer formed, then further intrusion in the interior stretched the surface. An alternative interpretation is that domes are the result of shallow intrusions of molten lava, causing the surface to rise. If they are intrusive, then magma withdrawal near the end of the eruptions produced the fractures. The bright margins possibly indicate the presence of rock debris or talus at the slopes of the domes.

Based on radar data from the Magellan Mission (1990-1994).  The simulated colors are based on images recorded by the Soviet Venera 13 and 14 spacecraft.  The image was produced by the JPL Multimission Image Processing Laboratory by Eric De Jong, Jeff Hall, Myche McAuley, and Randy Kirk of the United States Geological Survey.
