Wind and waves pummel the coastline, and—in the case of a beach in New Jersey—a historic treasure emerged from the sands. Last week, Island Beach State Park posted photographs on social media that appear to feature timber remains studded with thick nails between the water and erosion line farther up the beach. Traveling northWhile its homeport was Provincetown, Massachusetts, at the time of the wreck, the Lawrence N. McKenzie was voyaging to New York City from Puerto Rico. “Beach erosion during the winter months is common at Island Beach State Park and is part of a natural, cyclical process. Each year, high-energy waves and seasonal storms remove sand from the shoreline, resulting in narrower beaches and steeper profiles,” Beach State Park explained.
