Fractured floor and a rim shot

Taruntius with Cameron on its Rim 

Crater Taruntius with Cameron on its Rim

Between southern Mare Tranquillitatius and northwestern Mare Fecundatatius lies the Copernican period crater Taruntius (57 km). This crater was some distance from the terminator but with surrounding smaller craters showing deep shadows, it is clear that Taruntius is a shallow crater. Note the deep shadow in Cameron (12 km) on the northwest rim of Taruntius. In addition to Cameron other rim features include breaches to the north and south along the rim and interesting rough ramparts to the lava floor beyond the crater especially southward. This floor fractured crater presents a small central peak surrounded by dark ash deposits from volcanic activity on the crater floor.

  1. Dale and Sebastian,

    Thank you for your comments. Dale it took me about 40 minutes to do the sketch. I did jot down some notes to myself first and that took about 15 minutes before I started.

    Frank
