I went to the falls to take some pictures, and I think It may have fallen on the ground. Either that or it's at the parking area (snow plow turnaround) at the end of Spruceton road, I parked near the western side of that lot and it may have fallen out when putting my pack in the trunk.
It is a tomahawk style head, with a pick on one side. It was in it's leather sheath. I still have the ax handle but if anyone finds the head I would much appreciate getting in touch with me and some way to get it back.
