The series reveals many of the superstitions and traditions of the mining culture, including the idea that women (especially red heads) near mines bring bad luck.
Plenty of speculation about paranormal behavior. Brief conversations about accidents, deaths, shootings, and other tragic events at the mines, but few actual details are discussed. Explosions are visible. Alleged human bones are visible.
Words like "piss" and "damn" are audible; "s--t" and "f--k" are bleeped.
