The results of a recent archaeological dig in Naples reveal prehistoric Native Americans created a canal dating back to at least 800 to 1,100 A.D.
Robert Carr, executive director of the Archaeological and Historical Conservancy, said indigenous people used the canal as a shortcut and probably for transporting goods.
This is the second recent excavation and radiocarbon testing of the canal.
In 2011, the conservancy collected its first sample after using ground-penetrating radar to find the canal’s location.
Carr said the site is part of a complex web of canals in southern Florida.
“These canals are the only transportation canals in North America outside of Mexico. So, in that sense they are a major engineering marvel that indigenous people have constructed,” he said.
Carr and the conservancy hope to collect more samples to test this year.
