The pink arrows point to a barrier beach, formed when waves from the ocean (on the left) washed away mud and piled up sand, after the mud and sand were delivered by the stream flowing in from the upper right. The yellow arrows point to interesting features. How did they form? A. Beavers dug through the barrier beach and threw the material behind them, forming the yellow-arrowed deposits. B. The stream flowing from the upper right is a braided stream, and the yellow arrows point to bars formed in that stream. C. The beach used to be where the yellow arrows are, but was moved seaward by the river, which flowed over the old beach. D. A sinkhole opened behind the barrier beach, and the yellow-arrowed material slumped into it. E. A storm broke through the barrier beach and pushed sand farther inland. Barrier beaches are piled up by waves, but especially strong storms often break through the beaches. Some of the sand at such new inlets is moved toward the land, often forming new beach-like deposits such as those indicated by the yellow arrows. Some sand is also often moved offshore into deeper water. The river would have buried or reworked the yellow-arrowed features if the river flowed over them, there is no sign of a sinkhole, and bars in the river can be seen to be lower and elongated, not on top and transverse as the yellow-arrowed features are.
