Wichmann is a bowl-shaped, lunar impact crater. It is located in the southern half of Oceanus Procellarum

Oceanus Procellarum

Oceanus Procellarum is a vast lunar mare on the western edge of the near side of the Earth's Moon. Its name derives from the old superstition that its appearance during the second quarter heralded bad weather...

on a low plateau formed from a wrinkle wridge. There is a small mountain chain to the north that curves away to the west; this is most likely the rim of a worn crater that was buried by the lava flow forming the mare. Additional low mountains lie to the south of the plateau on which Wichmann is situated.
