The South Pole Of The Moon

Happily I am of the age when I feel free to call it as I see it.

See this link https://quickmap.lroc.asu.edu/?extent=165.6402957,-88.734362,72.0225488,-82.355612&proj=27&layers=NrBsFYBoAZIRnpEBmZcAsjYIHYFcAbAyAbwF8BdC0yioA

The South Pole of the Moon (of Earth) appears to be circular,

with (sloppy) directional arrows.

Is this apparent hole at the South Pole an entrance ! ? ! It seems too round to be an illusion.

And who flattened the foundation of the directional arrows so perfectly level?
