Shelby the Swampman uses an airboat to search for a treasure trove of century old logs in a legendary lost canal. In Washington, Rygaard tries to haul out the biggest log on their site–a mammoth six-ton cypress. In the Wyoming wilderness, while David Zitterkopf delivers the first load of logs to the mill, his sons struggle to hold down the fort. In Alaska, Adrianne steps up and takes a shot at working on the landing for the Papac crew. In British Columbia, the most rugged section of the Britannia site puts Triack to the test. And in Florida, the Dreadknots are firing on all cylinders, but an accident late in the day could be a game changer.
