Not far from the Boneyard, the town of White Sulphur Springs was devastated by a recent flood. Mark and the guys step up to help their neighbor rebuild, Barnwood style. They repair a garage by wrapping it in barnwood and use log skins to transform a prefab shed into a log cabin playroom. Mark also visits a modern Montana home covered in log skins.

Mark challenges his crew to build a log fort on the Boneyard. They use spare logs and some serious hillbilly know-how to construct a pioneer cantilevered fort, but when the temperature takes an unexpected plunge, the job becomes more difficult.
