Yuma Territorial Prison Museum
The Yuma Territorial Prison opened in 1876 and was pretty much hell. The first seven inmates built their own cells. It was constructed on a bluff above the Colorado River, which would flood three months out of the year and turn it into a peninsula. If you were caught talking you were chained to the floor. The heat was insufferable. Six men occupied one cell, and the lone chamber pot was emptied just once a day. If you were bad (which is a relative condition in a prison), you were sent to the Dark Cell.
