||* Mare Nectaris-- at 220
miles in diameter, is a thin sheet of lava that fills just the inner part
of the much larger Nectaris Basin that is 540 miles in diameter. You
can just make out a portion of the Basin perimeter at about 8 o'clock and
11 o'clock and at twice the diameter of the mare's center.
Theophilus is the youngest
of the "pre-mare craters" bordering the western side of the mare
and is also the best preserved. If you look closely, you can see the
flow pattern of lava filling in from north to south and flowing around the
east side of Theophilus. Madler and Rosse are the
only "post-mare" craters visible at this magnification.
Notice their near perfect and un-eroded shape.
