Ironwood State Prison (ISP) is a state prison located south of Interstate 10, in a detached section of Blythe, California, that lies west of the main portion of the city. It is located in eastern Riverside County, California, adjacent to Chuckawalla Valley State Prison. In 2014, the Anti-Recidivism Coalition teamed up with the Ford Foundation and others to host a TEDx conference inside Ironwood with hundreds in attendance, including Richard Branson.
