8-A

Eight-foot caisson sunk in Season 7 about 20 feet southwest of OC-1, placed from the Erwin Hamilton map to hit the Shaft Six tunnel. It hit axe-cut wood and leather near 103 feet and an oak timber and a pointed iron object at 114 feet, then only water and sediment below 140 feet, and was terminated.
