If Captain Harry Jackson had his way, there would be no Okefenokee Swamp. The Suwannee Canal was built to drain the wetlands and turn it into farmland and homesteads, but when he ran out of money, that plan was abandoned. Later, a lumber company devoured the ancient cypress forest, then left. In 1937, Okefenokee became a National Wildlife Refuge and began its slow healing back to its former glory. Even though the manmade canal, canoe trails, overnight platforms, and a few old cabins have remained, the Wilderness Act allows most of the 630 square mile refuge to remain wild.
