Wife and I take 4 mile trail walks in this wildlife management area several times a week. On todays walk on one of the gravel roads I see a small piece of this object sticking up, looked like dirt bike tract uncovered it. Normally I'm pretty decent on identifying old parts (because I'm old). This part is all solid steel or iron, no threads, small machine notch on small end, looks to be some hammer marks on the big end, I will look again with a magnifier for any numbers. This is what it looked like after some time on a wire wheel, as found it was covered in a thick layer of rust and crud, about 3 in. long.
