January 1934 Clearwater, Fla. The general level of Clearwater along Fort Harrison Ave is not more than 30' above present sea level. It is the old Pleistocene sea bottom. At about 20'-25' above sea level is a wide spread shell bed replete with large gastropods, near the corner of Osceola Ave and Demands street (to fishpier) in the place where I made my collection. From Fort Harrison Ave out to the Gulf there are at least four terraces or slopes. These shells appear to be concentrated due to weathering and erosion carrying away the sand and drag the heavier shells behind.
