This crater chain in southern Mare Serenitatis is clearly of internal origin because it is lined up parallel to several fault valleys or grabens. The craters in the chain do not appear to have any rims; consequently, they may have formed by collapse and not by the explosive ejection of volcanic material. The large crater in the right side of this scene, however, has a rim and so cannot be the result of collapse alone. The finely lineated texture across the left side of the photograph is caused by ejecta from the crater Dawes to the south.    - H.A.H.
