The Curse of Oak Island

Digging up the swamp

While the eye of the swamp is drained, Gary Drayton and Rick Lagina head to the shore of Lot 17. They discover a piece of scrap lead. Back at the swamp, boulders are found. Also found are large tree stumps, one of which has an iron rod embedded in it. Later, very large boulders are found on top of a layer of smaller rocks. (Season 7 Episode 16)
