This very high resolution image features three impact craters of nearly the same size that overlap to form a cloverleaf pattern. All three have rounded rims, indicating that they are relatively old. Determining the sequence of events is difficult. It may be that the one at the bottom formed most recently, blasting away sections of the rims of the other two.
