Hog Island


This is a barrier island off the west coast of Florida which became a state park on 12/07/1981. It consists of 385 acres of land and 2400 acres submerged. This island and Caladesi island were originally one island called Hog island until a hurricane hit in 1921 which created Hurricane pass that cut the island into two islands. The material found on the beach is from the Tampa Member of the Arcadia formation, which straddles the Oligocene - Miocene boundary. Most of this material was dredged from just offshore to build up the beach in the 1960's before it was a state park. This area is one of the few outcrops in Florida that has true flint instead of chert. The native Americans used to quarry the flint from this island.

Replacement samples of coral by Chalcedony, with more or less abrasion in the sedimentary system, are transported to the beach after major storms.
