(Above photo: a view of the “bog” from the northeast corner. You can see Japanese barberry in the foreground.” In the mid-ground, there is vernal pool. In the background, you can see the “bog”.)
These are pictures of water flowing through the “bog.” At this location, there was a very slight ripple and you could plainly see some algae filaments waving in the passing water. While, most of the water at the site was not noticeably moving, here and there you could see places like the one pictured below with water flowing.
