A Tom Sawyer day, camping on an island on the Mississippi in July of 2001

This pile of RipRap is the beginning of a "wing dam" that extends out into the river to the channel. You can detect the effect it has on the water by the dark line that extends from the point of the island to the right (watch out for your prop)
