Pat Shingleton: "Mounds... Of Evidence"
The Canaveral National Seashore and Everglades National Park have prehistoric shell mounds, 50 to 70 feet high. Scientists believe the mounds served as foundations for structures and settlements. They also served as navigational landmarks during European exploration of the region. These mounds, located on some of Florida's most pristine beaches, are at risk of washing away. Sea level rises could eliminate thousands of years of archaeological evidence. National Park Service Archaeologists are trying to minimalize the impact on these cultural sites. Science Daily reports that researchers investigated current temperature and storm system data and log books from Spanish forts and ships. The data will create a model for further protection.
