Mare Orientale
The southwestern half of this walled plain has been heavily damaged by the mass of ejecta from Mare Orientale. This material forms an irregular striation in the surface that is radial to the Mare Orientale basin. As a result, only the northeast part of the crater is somewhat intact; the remainder just forms an uneven depression in the surface that is covered in long ridges and gouges. The most notable feature in this section is the small bowl-shaped crater Lagrange D.
