pair of large craters stands out sharply on the moons north east
quadrant. Atlas, on the left is 53 miles in diameter and over
9000 feet deep. A fantastically complex crater, the rim terraces
rise high over the craters floor, which is covered with hills,
lava channels and small craterlets.
On the right is
the similar sized Hercules, some 42 miles across. This crater
is deeper, some 9700 feet deep and forms very steep slopes on
the inner terraces. This crater is famous for the two dark spots
on its interior floor which are most evident during the full
moon and nearly disappear during the partial phases.
