Are these photos of a footprint I found by our canal?

I realize the footprint (if that is what it is) is rather hard to see, but it is there, beside my camera case and also beside my foot. It was human-sized, and appeared to have a heel and possibly a toe line across the top, but it was really hard to determine for certain. I only found one, and wish there had been more to correlate with the one possible track. It was beside a tree, and to be quite honest, it is hard to determine anything from it. Right now, I give it a 40% possibility of being a footprint, with 60% open to it not being a track. If I find anything else that correlates to it, I will report it here.
