The building of Mt. Lemmon Highway began in 1933. Labor for its construction came from prisoners in a "Federal Honor Camp". This photo shows what remains of the employees housing they constructed during this time.
The prisoners were men who had broken tax laws or immigration laws; objected to joining the military in WWII for moral and religious reasons; and those who objected to the internment of Japanese-Americans.
Gordon Hirabayashi was one of the internment objectors who was imprisoned here and the site bears his name.
