14.10.11. We spent much of the day in frustration trying to get three piles down to the planned depth, level with the others we'd put in. We finally had to leave one above the level of the others to decide how to deal with it later. We even cut an angle on the bottom of them to help penetrate to depth. But we know the cause is some bottom planking of a barge sunk in this position in the past. Even the professionals have difficulty getting piles through wood.
