But, at least the boggy stream in a large meadow east of that had mud exposed in the same stretch as last year. 
I took 24 pictures of patches of mud around the area. Enjoy! 
Pix 1-5:
The first 2 are of a patch of mud in the main beaver pond, which is actually not attached to the bottom. If you were to jump out onto it, you would immediately plunge into the water beneath the floating mat of peat!
Here are a bunch of pix from the stream just to the north (downstream) of the main pond, with some orange algae on the mud/water:
However, while it was flooded, the mud became loosened to the point that mats of vegetation I had pushed under along the edges last fall had floated back up to the surface, and was scattered over top of the bog, making it look rather interesting, which I then worked into my video. After doing my video, I pushed all the floating clods under the vegetation at the edges of the bog or tore them up, to make my entire bog open again. However, because the newer parts of the bog were thinner and watery, especially on the east (pondward) side, some of the thicker mud moved into it during my movements through the mud, lowering the bog's level down to a point where the surrounding water, still relatively high (with surrounding vegetation floating) around part of the outside of the bog, spilled over the surface, flooding it over again.
