Often I show image covering from Aristoteles to Hercules in sunrise. But here I want to zoom in on a small area of that region this time at sunset. Just above center in this image is the crater Burg (41km dia.) in the center of the rough hexagon of Lacus Mortis (155km). The detail in the eastern wall of Burg is nicely displayed here along with several of the diverse rimae on the floor of this Lacus. Below Burg are two wonderful craters, the flat floored Mason (44km) on the right and Plana (46km) with the little central peak to the left. That central peak, with the 3km impact crater on the south side, is only the tip of what was once a much larger mountain but for the lava flooding of this crater that filled up the interior. The only feature on the floor of this crater seen here is a small (2.5km dia.) crater at the tip of the shadow from the central peak. South of these two is Lacus Somniorum of which you can only see a small northern portion here but interestingly just south of Plana you can see the dome Mason-1 which is well shown on the floor of the Lacus. This is always an added a treat when observing in this area!
