Summary
| Description |
English: Lock 40. NPS site says: Lock 40 is a gray-blue limestone lock with a 6' lift, it conforms to standard dimensions. A portion of the upper berm lock gate and balance beam remain on the floor of the lock. The gate has two wicket gates at its base. The gate was creosoted, which has aided its lasting power. Early movement of the lock walls is indicated by extensive cutting back of the face stones of the lock side walls, particularly on the berm side. Evidence points to a wood timber foundation. |
