Considerable information has been published during the past decade supporting the concept of a relatively high sea level during the mid-Wisconsin Farmdalian substage; however, confirming evidence is absent in the voluminous literature on Gulf Coast geology. This paper discusses certain recently recognized evidence in the form of buried weathered horizons and beach trends in the Pontchartrain Basin area of Louisiana and calls attention to additional overlooked and possibly relevant features from elsewhere along the Gulf Coast. Included in this category are apparent beach ridges in southwestern Louisiana, beach rock and related shoreline deposits in various coastal areas, discontinuities within entrenched valleys beneath coastal bays, an abandoned Mississippi River meander belt in south central Louisiana, and a Pascagoula River terrace in southeastern Mississippi.
