Geological Chronicle
Gutenberg lies along the west edge of Mare Fecunditatis in the eastern part of the visible Moon, spanning 70.65 kilometers in diameter. Named after German inventor Johannes Gutenberg, the impact formation lies north of the Montes Pyrenaeus that run south from Gutenberg, with the craters Goclenius, Magelhaens, and Colombo situated to the southeast.
The rim of Gutenberg is worn and eroded, most notably in the east where it is broken by the overlapping crater Gutenberg E. That crater features gaps in its southeast and southwest rims, opening a passage to the lunar mare to the east. Clefts and valleys mark the southern rim where it joins Gutenberg C, while Gutenberg A intrudes into the southwest rim.
Lava flooded the floors of Gutenberg and Gutenberg E in the past, forming a relatively flat plain across the bottom. A pair of clefts forming part of Rimae Goclenius breaks across the northeast floor, extending northwest from the Goclenius region. A central rise formed by a semicircular range of hills remains prominent in the south, opening eastward.
