Later in the afternoon I spontaneously decided to return to the trails where most of the butterflies I saw only two hours earlier were seen. By then the temperature had dropped and the wind gusts had picked up enough to almost force my bike to a stop on more than one occasion. Not good butterfly weather! I never did see any more butterflies. But that was fine because there were other things I wanted to see.
 
First I went off into the Jack Pine plantations to see if I could find evidence of former land-use. This was all open agricultural land at one point, so perhaps there were tools, fencing, ruins, etc hidden in the bush. I have already found rolls of wire fence, a tractor engine, and a seat from a tractor. Today, deep within one of the plantations, I found a few more fence posts with wire and a corner post with a pile of rocks.
 
Next I moved on to a more obvious evidence of former land-use. This stone foundation ruin is part of a collection of ruins all within a short distance of each other. This ruin and an adjacent stone foundation ruin are right beside the main trail through the area and in the case of the latter the trail makes a sharp diversion around it. I see these ruins all the time, but today with extra time on my hands I stopped to look around.
