This image is a view down the length of a "Rip-Rap" structure on the riverbank composed of many logs lying side by side, slanting toward the water and partially covered with medium-sized rocks perched on horizontal logs anchored midway on the slanted structure. The far portion of the structure is also anchored with rocks at the bottom on the edge of the water visible in half the photo at left.
