I worked on this about three years ago, the location is in a bad place, Fort Knox military reservation.
If you look at a topo map just to the southwest of Louisville KY. and find the salt river, locate a branch called rolling fork it is the county boundary between Hardin and Bullitt county's. follow south on rolling fork and you will see the boot it is part of the branch. At the mouth of rolling fork look a little to the northeast and you will see the lower bottom of the headdress, Its the points of the hills. From what i can remember the nose and fore-head were part of the Ohio River. Bad thing is the head is inside Fort Knox. You can trace the head on a topo map. I think there were to drill holes on the southeast side of the headdress this you will find on a topo map. The one thing i never checked on was the date carved below the head and boot. Could there be a hill or ridge just to the southwest of the head and boot, that may have a rock carving on it, a pile of rocks, a pond? This was supposed to be Chief Doubleheads treasure? It may be fake, because the head covers many miles, could have been put there using a topo map? i just don't know
