There was still some water on the east side, and a lot of the mud was still quite soggy on top, but it was way better than I had last saw it! 
I had a nice dramatic sink and escape there in front of the camera, and then afterwards, off-camera, spent a while submerged with swim goggles and a breathing hose, then just brief submergences without the hose, then lingering with my mouth exposed, then my face exposed, and then crawling over the entire area. This time, unlike last time, all surface water disappeared with the activity, leaving the entire bog with hardly any water on top, quite a difference from how I had left the bog last time! Here are 25 pictures of interesting looking spots around the area, including my main sinking spot, shot that day:Pictures 1-5:

A look at my sinking spot, re-exposed again, with only a little bit of water left. Something small went through it, leaving a trail through the mud on the east side (side closest to the pond):
A close-up view of the muddy area. Does it look like a treacherous patch of bottomless sucking quagmire? Try jumping in, and you would find out!
