Turtle Mound is a historic site located 9 miles (14 km) south of New Smyrna Beach, Florida, on State Road A1A. On September 29, 1970, it was added to the U.S. National Register of Historic Places. It is the largest shell midden on the mainland United States, with an approximate height of 50 feet (15 m). Turtle Mound was estimated to be 75 feet (23 m) high before it was reduced by shellrock mining in the 19th and 20th centuries. This mound contains 33,000-cubic yards of oyster shells that covers 2 acres (8,100 m²). The turtle-shaped mound contains oysters and refuse from the prehistoric Timucuan people. Archaeologists believe that these people may have used this site as a high-ground refuge during hurricanes. With bow and arrow, spears and snares, they caught a variety of small mammals and reptiles.It was constructed between 800 and 1400 AD. Early Spanish explorers and subsequent mariners utilized the large mound as a landmark. Today, the site is owned and managed by the National Park Service as part of Canaveral National Seashore.
