Figure 21. Erosion of the dunes and maritime forest at Popham Beach State Park is visible from the Seawall Beach spit. Sand that is eroded from the park is swept by ebb currents (to the right) and flood currents (to the left) and redistributed to other parts of the beach and also onto the beach spit. MGS file photo by S. M. Dickson taken November 4, 2008.
