NASA Image Shows Anomaly on The Side of Crater?

Look at this anomaly i found when looking at Apollo 11 images. Does this show something built onto the side of a crater? The shape appears as a hexagon built or caved into the crater with a large black triangle structure that is positioned in the center of the hexagon outline. The structure seems to be elevated upwards and appears black when compared to the surrounded area.


The anomaly shows up on a number of frames as seen below...

Look at the crater wall and locate the black spot that seems to stick out. The black spot seems to be surrounded by a possible hexagon outline.

Look at the black spot now look just a bit to the left of the black object and notice the two straight lines that cast a shadow.

Another frame from Apollo 11 shows the same anomaly but from a different angle. Again look at the two elevated lines that appear to be suspended above the wall of the crater that connect to the black object.


Do you think this is a natural formation? or is there something else going on here? what does everyone think of this?
