12 photograph taken from orbit showing the Davy crater chain, a
string of craters extending about 50 km across the floor of crater
Davy Y. The large crater at the top of the image is Davy crater,
34 km in diameter and centered at 11.8 S, 8.1 W. The crater chain
has been hypothesized to be a volcanic feature, a string of secondary
impact craters, or craters due to multiple impacts from a Shoemaker-Levy
9 type object. North is to the right.
