Figure 9. Illustration of a topographic cross-section over Half Mile Beach showing the elevation of the frontal dune ridge. The position, depth, and composition of two cores, one from the beach and the other from the back-barrier marsh near Todds Point are shown with a compressed horizontal scale (vertical exaggeration is 4x). This figure shows sand overlying peat in core RO-5 on the beach and thick high marsh overlying low marsh peat in core RO-5A with a basal salt marsh age of 3,570 (radiocarbon) years. Modified from Figure 4 of Buynevich and FitzGerald (1999).
