The Lemon Bay Historical Society is hosting the first public presentation on a huge archaeological find off Manasota Key. It’ll be in Englewood on Tuesday at 7pm at Englewood United Methodist Church. The site, which was found about 350 yards off the shore of Manasota Key in 20 feet of water, is the first preserved prehistoric burial site in the Americas to be discovered in offshore waters. It’s estimated to be around 7,000 years old.
