  • The most intact portion is in the south, although even this rim is worn and has a valley to the southwest.
  • The rim is worn but still retains a well-defined edge.
  • The rim is worn, and several tiny craterlets lie along the edge.
  • This crater has a circular, symmetrical shape but the rim is worn and does not project very far above the surface.
  • The remaining rim is worn and eroded, with a number of small craterlets along the edge and inner wall.
  • The surviving rim is worn and eroded, forming a low, circular mountain range.
  • The remainder of the rim is worn, with a pair of small craterlets along the northern rim and inner wall.
  • The outer rim is worn and eroded, although it retains a generally circular form.
  • The remaining rim is worn and rounded, and the crater is now essentially a depression in the surface.
  • The remainder of the rim is worn and rounded, and the interior floor is otherwise level and featureless.
  • The outer rim is worn and Boussingault K lies across the northwest rim.
  • The remaining rim is worn and rounded from smaller impacts, although the perimeter can still be clearly discerned.
  • The remainder of the rim is worn and eroded, so that the features have become rounded and somewhat irregular.
  • The surviving section of the rim is worn and eroded, forming an arc-shaped range of low ridges in the surface.
  • The remainder of the rim is worn and somewhat distorted into a hexagonal shape, with several small craterlets along the rim edge.
  • The southern and southeastern rim is worn and eroded, but the outline can still be discerned.
  • Like both of these craters, Hagecius has undergone erosion from subsequent impacts, and its outer rim is worn and irregular.
  • The remainder of the rim is worn and irregular, forming a mountainous arc that is widest in the north.
  • Alden has a low rim that is overlain in the north and northeast by Alden C and the smaller Alden E. The rim is worn and eroded, especially along the southern wall.
  • The rim is worn and eroded, with a tiny crater along the northernmost part of the rim, and an inward bulge along the northern half of the inner rim about 60% of the distance from west to east.
