Kies is the remnant of a lunar crater that has been flooded by basaltic lava, leaving only a remnant of the outer rim. It is located in the Mare Nubium almost due south of the crater Bullialdus. Northwest of Kies is König. To the south-southwest lies a lunar dome structure designated Kies Pi (π). It has a small crater at the top, and is most likely volcanic in origin.

The rim of Kies has numerous gaps, and forms a series of ridges in a ring-shaped formation. The most intact rim structures lie in the south and northeast sections of the wall. A low promontory ridge is attached to the southern end of the rim, pointing southwards.

Satellite craters[edit]

By convention these features are identified on lunar maps by placing the letter on the side of the crater midpoint that is closest to Kies.
