CJn the Atlantic side of Cape Cod traverses have been maintained at the following places; Nauset Coast Guard Station, the aban- doned Highland Light Coast Guard Station, and about three-quarters of a mile west of the Race Point Coast Guard Station. The first site is a traverse off the southward growing spit which protects the Eastham-Orleans shore, the second is off a cliff section which is shedding debris of all types, and the third is off the north side of the Provincelands section where the shore is being prograded by a succession of beach ridges and offshore bars. The exposure to onshore gales is severe and is about the same on all three, although the tidal currents run stronger off the Race Point traverse. Wave action is as violent as you can find anywhere on the Atlantic coast. On the Cape Cod Bay side, two traverses have been maintained: one at Sandy Neck, Barnstable, and the other at Duxbury Beach. On neither of these beaches is wave action as . violent as on the outer Cape, although wind velocities are probably as high and dunes have been extensively developed, especially at Barnstable. Geologically, both are wave-built spits. In the case of Sandy Neck, the source of the sand is the cliffs north of the Cape Cod Canal, but at Dux- bury the source is not apparent, possibly coming from the bottom off shore. Both seem rela- tively stable and have exhibited little topographic change from year to year. They present a marked contrast to the outer Cape where every storm brings marked alterations in width of the backshore and in the position and height of the berms, as well as shifts in the offshore bars of the seaward portion (Fig. 2). For any given set of environmental controls,. Figure 2. The outer beach of Cape Cod looking north. Note the marked variations in width and the position of the offshore bars as marked by the line of breakers. looked at in the large,
