LO-IV-184H Pomortsev is the irregularly shaped crater above center. The 7-km diameter circular crater above it is Dubyago N. The long shadows in the lower right are being cast onto the floor of 37-km Maclaurin O. They correspond to height differences of up to about 2800 m. The 8-km circular crater on the floor of Maclaurin O is unnamed.

AS10-29-4241 and AS10-29-4242 are two of Apollo 10's orbital Hasselblad photographs of the somewhat "rectangle"-shaped dark crater Pomortsev, visible near the centre of both frames. Photographs made during high solar illumination.
AS10-30-4496 also shows the rectangular shape of Pomortsev, touching the eastern rim of Mare Spumans.

Description
This is a small complex crater that has been flooded with mare lava that rose up fractures under the crater and covered its central peak and wall terraces. The crater is only preserved because it formed on a relatively high spot - the rims of older features. It is one of the many features that was inadvisedly named in the 1970s; its previous lettered status is more consistent with its value as a landmark.
