It's kind of hard to tell, but there are two men sitting by the shelter in each photo. Here is a zoomed-in view.
Also interesting in the first photo is what appears to be a pair of signs on the tree to the left of the shelter. Even though these are high-res scans I can't make out what the words say, except that the first word on the top sign almost looks like "WANTED." Here it is zoomed-in.
So if you've ever gone exploring along Herman Creek and come across the remains of an old shelter, this might be it. (Although it is possible that these photos were mislabeled - I have come across that several times already during my research.)
