Crater Demonax demonstrates many smaller impacts on its southern rim. Boussingault crater is the largest of the craters in this sketch and is actually made up of two craters one inside the other (concentric). Boussingault A (72 km.) lies inside Baussingault with its floor completely in shadow.
This was an enjoyable session with our Moon.
