Approximately 500 ft. West of the cache location is a railroad bridge known as "Hangman's Bridge" where lynch mobs hanged at least four persons in the wild days. In the early hours of January 7, 1869, Luke Barnes, Lee Watkins and James Sponder, Black soldiers of the 38th U.S. Infantry, were hanged here, while awaiting trial for the murder of James Hayes in Hays City. On August 11, 1871, another mob hanged Jack McGee, a mule team driver being held in the town-county jail for stabbing Big Creek Township’s constable Frank Shepard.
