Here are a couple of nice screen shots from the 1935 Tom Mix serial "The Miracle Rider," featuring an actor who might have played bad guys more than anyone else in movie history, Charles King.
These shots are from a scene filmed on the Lower Iverson, with King seen here against some of the rocks that make up the Devil's Doorway cluster.
I really like these two shots. Charles "Blackie" King was in 400-plus movies, almost always as a baddie. If you want to see a great site about Charlie King, please click here.
