Figure 4.1. Interpretive geologic map showing five physiographic zones on the inner continental shelf, including Ebb-Tidal Delta, Nearshore Ramp, Outer Basin, Rocky Zone, and Shelf Valley. Physiographic zones are superimposed on gray-scale, shaded-relief bathymetry except in areas adjacent to the shoreline in shallow water landward of the survey area. See Section 4 – Interpretive Geologic Mapping for a detailed description of each zone. Index boxes and profile lines show locations for other figures used in this report.
