Barrier islands are common features along the Atlantic and Gulf Coasts of North America. Their exposed position and low physiography make them extremely vulnerable to hurricanes and northeasters. Overwash, the transport of sea water and associated sediment across the island during storms, is a major component of the island's response to these high energy conditions. This article attempts to characterize overwash deposits and interpret an overwash sequence. Results from the comparison of channel deposit data for textural grading across the washover fan were inconclusive.
