I found a Bearing Tree. Not knowing what it was, I took a few photos and went on my way. This Bearing Tree marker, placed in September of 1979, is a survey marker indicating the corner of some kind of plot. That plot might have been someone's property or the boundary between national forest or was even used to mark state lines (which isn't applicable for this one). The location of the corner for the survey isn't at the location of the tree, instead this marker tells you how far away and in what direction the corner is. It's an interesting piece of history.
