It has been estimated that 90% of women living in Deadwood, South Dakota in 1876 were prostitutes. It was difficult for a woman to make a living in the American West, especially if she did not have the protection of a father or husband, and many single women turned to prostitution as their only option. According to historical accounts, Charlie Utter's famous wagon train of prostitutes arrived in Deadwood in 1876 to find miners lined up along the street and cheering their arrival. The women were accompanied by two madams who had chosen the professional names Madam Dirty Em and Madam Mustachio. Prostitution proved to be a thriving industry in the male dominated town of Deadwood and continued almost without interruption until the State's Attorney's Office closed the last four brothels in 1980.
