Overwash fan on Topsail Beach
Figure 8 shows an extensive overwash fan located behind the main road to North Topsail Beach. The sand that forms this feature was brought here during Hurricane Fran. It has increased the elevation of this back beach area, but only as a result of the flattening of the upper beach and dunes that once lay seaward of it.
