Figure 25. This figure is a shaded relief map of Seawall Beach, the Morse River, and Popham Beach in Phippsburg, Maine. The shaded relief image was generated by Peter A. Slovinsky of the Maine Geological Survey using NOAA Coastal Services Center LIDAR data acquired in 2004. The yellow line marks the November 2008 position of the last high tide swash line (elevation approximately 8 feet above mean lower low water) and serves as a contour of the spit as well as the berm edge along the Seawall Beach dunes. The blue line approximates the highest elevations on the beach spit where they could be mapped in November 2008. The spit becomes very flat on the eastern end so a ridge could not be mapped. The red line is a June 7, 2007 shoreline survey along the seaward edge of the dune at Popham Beach State Park conducted by MGS.
