MARE AUSTRALE

Mare Australe is located in the southeastern hemisphere
of the moon. It overlaps the near and far sides of the moon,
and is 603 miles in diameter. The basin containing  
the mare is of the Pre-Nectarian epoch, while the actual
mare material is of the Upper Imbrian epoch. Smooth, dark 
volcanic basalt  lines the bottom of the mare. Notice the 
crater Jenner in the middle of the photo, this is an Imbrian 
crater that was later filled with mare basalt. Just to the
left of Jenner is the crater Lamb.
