The lunar limb sections cover more territory and this one is no exception.  The most dominant feature is Pasteur, a large (224 km) lunar impact crater (better known as a walled plain) on the lunar Far Side. The vicinity of this crater is occasionally brought into view from Earth due to libration, although not much detail can be seen. Lying along the southern rim of Pasteur is the smaller crater Backlund. Just to the southeast is Hilbert, another walled plain which is labelled in the color version above, nearly two-thirds the diameter of Pasteur.  The outer rim of Pasteur is generally irregular, with sections being heavily damaged by multiple impacts. The northern rim in particular has been nearly obliterated by overlapping impacts, and the southern rim is not in much better shape with a stretch overlain by Backlund. The southeast rim of Pasteur is nearly linear near where the ground has been modified by Hilbert. Even the western rim is heavily damaged, with overlying craters Pasteur U, Pasteur T, and Pasteur Q. (The first of these, Pasteur U, forms a merged group of overlapping craters.)  The interior is not in much better shape, with the southern half irregular from ejecta covering the surface, and several small craters lying across the floor. In the northwest part of the floor is a short chain of small, overlapping craters forming an arcing line from north to south. Further to the right of Pasteur is Langemak, a prominent 97 km-wide impact crater less than one crater diameter west-northwest of Danjon, and nearly due east of Meitner. To the southwest of Langemak is Kondratyuk. Langemak partly overlies the larger and older crater Langemak N. This feature is also attached to the northeastern rim of Kondratyuk. To the northeast of Langemak is the crater Necho (out of frame), an impact feature that lies at the locus of a bright ray system. Ray material from this impact lies across the rim and interior of Langemak, particularly along the northwest and eastern halves. The outer rim of Langemak is relatively fresh and well-defined. The most notable impact along the rim is the small crater Sherrington along the southwestern edge. The remainder of the rim is roughly circular, but irregular with multiple small outward bulges. The inner wall is terraced in places, with the appearance of slumping along parts of the upper edge. Within the interior is a low, curving central ridge near the midpoint. There is a patch of lower albedo material to the southwest of this ridge, extending to the edge of the inner wall.
