Figure 5. The map base is a 2009 air photograph. The colored blue line shows a shoreline survey of the low-tide position of the Old Morse River on November 5, 2011. For comparison, the orange line was a survey of the July 19, 2011 dune edge (see also Figure 2). Note about 50 feet of upland dune loss in the vicinity of the bath house between July and November. In this image, the low tide line is inland of the dune line (approximately the spring high tide line) in July. The narrow area between the two blue lines is where water remained at low tide. The outer cut bank of the Old Morse River channel is clearly delineated by the curve in the northernmost blue line. The yellow line delineates the portion of the sand spit that was above the high tide line on November 5, 2011. See Figure 7 for an oblique air photo taken on November 6, 2011.
