Simple impact craters have bowl-shaped depressions, mostly with smooth walls. This type of crater generally has a diameter less than 9 miles (15 km). Their depth is about 20% of the diameter.
Complex impact craters have a single or multiple peaks in the middle of the crater. These craters have diameters between about 12 and 110 miles (20 and 175 km), and the central uplift is usually one or a few peaks. Craters with a diameter over 110 miles (175 km) can have more complex, ring-shaped uplifts within the crater.
The lunar basin Schrodinger is 200 miles (320 km) in diameter. Schrodinger also has an inner ring which is 92 miles (150 km) in diameter and about 75 percent complete. Schrodinger is one of the youngest impact basins on the Moon.
Impact Basin: A impact basin is an impact crater that has a rim diameter greater than 185 miles (300 km). There are over 40 impact basins on the Moon. These catastrophic impacts produce faulting and other crust deformations. Material ejected from impact basins is distributed over wide areas.

You obviously put a lot of work into this and that is great. The moon is a great topic of discussion!
If you would, could you point out your very favorite couple of anomalies out of this collection and take a stab at what they might be? (unnatural structures, ancient ruins, etc).
Or do you think they are all naturally-created, but just look anomalous compared to the majority of other lunar locations?
Perhaps jkrog08 can explain how craters can have 6 even sides...more than a few times
The possibility of impacts of large meteorites on the thin crust of the early moon accounting for the formation of the hexagonal lunar craters is discussed. Solidified basalts comprising a lunar crust of thickness 10 to 50 km characteristic of the earliest stage in lunar evolution are shown to have a large-scale hexagonal pillar structure, due to the effects of shrinkage. Results of experimental simulations of the propagation in this hexagonal pillar structure of the shock wave generated by the impact of a meteorite of diameter 10 km and mass 10 to the 15th kg on the lunar crust are then presented which demonstrate the pushing away from a central circular shock of pillars resting on a low-friction surface in a hexagonal pattern.
I seek only the truth. But let me make it perfectly clear how little I think I know:
1. All of my claims are only possibilities.
2. I could be completely misinformed.
3. All of what I believe might not be true.
