cribs were built on rubble-mound foundations. The easternmost 800 ft
of the structure was 24 ft wide (Figure 8, Section C), the adjacent
50-ft portion was 20 ft wide (Figure 8, Section D), and the
most 50 ft of the breakwater was 16 ft wide (Figure 8, Section E .

Construction of a 326-ft-long rubble-mound shore connection of the
