History The swamp has a rich human history including Native American settlement, explorations by Europeans, a massive drainage attempt, and intensive timber harvesting. Native Americans inhabited Okefenokee Swamp as early as 2500 BC. Peoples of the Deptford Culture, the Swift Creek Culture and the Weeden Island Culture occupied sites within the Okefenokee. The last tribe to seek sanctuary in the swamp were the Seminoles. Troops led by General Charles Rinaldo Floyd during the Second Seminole War, 1838–1842, ended the age of the Native Americans in the Okefenokee. The Suwannee Canal Company purchased 238,120 acres (963 km2) of the Okefenokee Swamp from the State of Georgia in 1891 to drain the swamp for rice, sugar cane, and cotton plantations. When this failed, the company began industrial wetland logging as a source of income. Captain Henry Jackson and his crews spent three years digging the Suwannee Canal 11.5 miles (18.5 km) into the swamp. Economic recessions led to the company's bankruptcy and eventual sale to Charles Hebard in 1901. Logging operations, focusing on the cypress, began in 1909 after a railroad was constructed on the northwest area of the swamp. More than 431 million board feet
