What is this?

I found this deep in the woods in michigan near a river. There are many Indian landmarks and marked trails near by. I have found artifacts here before, but what is this one?

Your item is only a rock, there is no apparent working by man. But it sounds like you may have a good area to search. ''Keep the Faith''
