I cannot claim any professional level expertise in geology, however what you suggest that the color of clay means is consistent with what I have understood and I would think it is relevant to my current problems. However in exactly what way it is relevant is not yet clear to me. If that is the usual water level there, I would think it odd that water would continue to descend into the ground at that point unless that water level was quite local and able to overflow into some nearby lower area.

Concerning the grey colour you observed. That may just be an indication for reducing (lack of oxygen) circumstances in the soil. That type of colour (grey, bluisch or greenish grey) is normal when you reach a level in the soil that is usually below groundwater.
Given the soupy nature of the clay that I was sinking into I would say that at that point I was at the level of the water table even if my feet were about 15 inches into it. As in each position I sank to the boot tops, I would stop and extricate myself before continuing with the task at hand.

Since you have only the photographs to judge by I would certainly agree that from those appearances they show cause for concern. However:

Bummer, Because of the limestone formations underlying much of the state this is an occurance which is much more common that most landowners to concern themselves with. But really severe sitiations are not actually that common though they do happen.

Well Missouri is a big state, so the definition of "Close enough needs a bit of definition. I live in the vicinity of Camdenton south of Lake of the ozarks and I just was up in Kansas City yesterday and it took 6 hours round trip. And that is not even half the way across the state. I can tell you that the state geologists would be happy to come out and take a look at it. The fellow that helped me was from the Missouri Geological survey and he dealt with this area.
