Within the Cliffside Mountain Canyon, is a large mine complex made up of several long winding tunnels leading from one entrance of the mine to the other. Both entrances are located on opposite sides of the river, thus making it a possible path to travel from north to south. The tunnel's interior is rather dark, difficult to navigate through and in bad condition. The area was formerly used for mining gold or coal, with several abandoned wooden structures and empty crates within the area. The mine is also quite rocky, with plenty of gravel, scree and boulders laying about the place.
