I decided not to portage around it, because the Mud River was, well, muddy.

I don't know if these boards where somehow part of the original railroad bed or where laid later. At any rate, this shows you how straight the road and flat is around here as an old railroad grade. A normal truck trail would not be like this at all.

I didn't explore, but at some point in the future, I will have to come back and see this area again.
