 Though the "Tybee Bomb" did not detonate (and, according to some reports, was not armed with a fuse), there has been ongoing concern, since the Mark 15 nuclear bomb lost during the mishap was never found.Native Americans, using dugout canoes to navigate the waterways, hunted and camped in Georgia's coastal islands for thousands of years.The Euchee tribe likely inhabited the island in the years preceding the arrival of the first Spanish explorers in the area in the 16th century.
