Figure 5. Eroding bluff and small beach on the west side of the esker (see Figure 2 for location). The beach here is too small to afford protection for the bluff, and so it erodes (note fallen trees). Dashed white line marks high-tide line. Bluff material is fine-grained glacial marine sediment, and forms a muddy substrate for salt marsh grasses (arrow).
