Looking up the wall of a lock in the St Lawrence Seaway. The spreaders of Issuma are just visible on the upper left. Small vessels like Issuma do not use the bollards that are set into the wall in this picture.

This is one of the two American locks in the St Lawrence (the other five are in Canada). Jordan is tending the bow line here as we descend. In the American locks, you pass your lines (ropes) around floating bollards–the yellow steel thing labeled `5` that slide up and down the lock side with the water level.
