Mason represents the remains of a heavily eroded impact crater on the south bank of Lacus Mortis in the northeast quadrant of the Earth's moon . It is closely connected to the eastern edge of the flooded Plana crater . In the northwest lies the Bürg crater and in the south the Lacus Somniorum spreads out.
The outline of the heavily eroded Mason Crater is irregular and elongated in an east-west direction. The rim of the crater is an uneven ring of crumbling hills that merge into the rough terrain in the south and east. Canyons or valleys break through the western rim and extend to the eastern rim of the Plana crater . The inside of the crater is flooded by basaltic lava and an almost flat basin within the crater rim.
In the north-western area of the crater floor the small crater 'Mason A' can be seen.
