In this photo, the older layers are on the left and the younger ones on the right. The structure shown is called a flame structure. The coarse-grained material in the center washed down the ocean slope in a dense turbidity current over the finer material on the left that was still unconsolidated and had a high water content. As the dense, coarse sediment deposited on the bottom it settled into the underlying sand which squirted up into the coarse sediment to form what looks like a flame.
