We also visited the Yuma prison.  Now shut down but was once the the most feared prison in the wild west.  It is referenced in several western movies like 3:10 to Yuma.

Cell block gate

50 Caliber protection

This is the inside of the 'Dark Cell'.  I used flash to show the rough walls on the inside.  This is an empty cell 6'X10' that is pitch black when the cell door is closed.  This was for solitary confinement.  I guess adding complete darkness to the already 120 degree temperature is all that is left to do. 

 

This is a typical cell.  Six prisoners to a cell 6'X8' again.  Also in the early years women who were sentenced to prison were put in cells with 5 other men.  The prison was open for over ten years before they added a cell for women.  Eighteen months in this prison seems worse than twenty years in a prison today.
