Figure 36.12 Pancake domes on Venus.
This cluster of four overlapping pancake domes is located on the eastern edge of Alpha Regio. The domes average about 25 km in diameter with maximum heights of 750 m. These features can be interpreted as viscous or thick eruptions of lava coming from a vent on the relatively level ground, allowing the lava to flow in an even lateral pattern. (NASA/JPL)
