San Castle is situated on the Atlantic Coastal Ridge, a relict shoreline and dune system associated with the Pamlico and Talbot terraces of the Pleistocene epoch. Formed when sea levels were approximately 30 feet higher than today, this ridge originally existed as a barrier island composed of accumulated sand and coquina.Due to the high elevation and well-drained sands of this ancient coastline, the area supports remnants of the Florida scrub ecosystem. This is one of the rarest and most endangered ecological communities in Palm Beach County, with less than 2% of the original scrub habitat remaining.
