I sooooo badly wanted to go under!!!!! After my off-camera sink, I also found that the cleanup water was a bit on the cool side, which made cleanup a bit longer. After that, it took me a while to warm back up after that first sink and cleanup. So, when I did my on-camera sink, even though I never submerged this time, I really put on a show, where my struggles really showed off how treacherous and hard to escape the mud was (that is, if you don't know the proper technique for escaping thick, bottomless mud with nothing solid within reach)! 
When I first reached the area, I had to pass the time to wait for things to warm up. My Crescent Road pond turnoff is on the north side of Crescent Road. A little further westward up Crescent Road are some more marshy areas south of the road, which includes two beaver ponds. The water level in one was low enough to expose the mud there, and here is a picture of it, taken at 12:18 PM (too bad this fine-textured mud was in sight of the road, since I would have loved to try it out):
Afterwards, I returned to my sinking area. Here is a roughly overhead shot of my bog, with the surface stiffened, with some very tiny fragments drying out, taken at 12:41 PM:
