I just stumbled upon this great, rustic cabin photo on Flickr. This is one of over 70 historic buildings in the smoky mountains. This is the John Oliver Cabin. It can be reached through the scenic loop road at Cades Cove.
The cabin remained in the Oliver family until the park was established. The cabin contains no pegs or nails because gravity locks the beams together. The open spaces between the logs (chinks) were filled with mud to seal out the rain and wind. The small windows and doors conserved heat and help maintain the building’s strength.
