Figure 3c. West end of section shown in Figure 3a. Note abrupt contact between gray and brown layered mud at mid-section of road cut. Unconformity between dipping beds and overlying horizontal beds at top of section marks transition between coarsening upward marine regressive sequence and tan shoreline sand. Unit is capped by a thin veneer of wind-blown sand (darker tan material at very top of section).
