LO-IV-164H South is the vaguely bounded region of rough terrain in the center of the frame. To its upper right is 24-km Robinson, and to the upper left a small part of 143-km Babbage with 14 km Babbage C on its floor.
(IAU Directions) SOUTH.--On the E. and S., the boundaries of this extensive enclosure are merely indicated by ridges, which nowhere attain the dignity of a wall. On the N., the edge of a tableland intersected by a number of valleys define its limits, and on the W. a border forming also the E. side of Babbage. The interior is traversed by a number of longitudinal hills, and includes two bright little heights, drawn by Schmidt as craters.
