First off, understand that Northern Lites Casino, Susanville Casino and Diamond Mt. Casino are all one and the same casino in the same location ( 900 Skyline Dr., Susanville, Ca. )and building since inception. That said:

Official opening (Nor.Lites.C.).. Feb. 1996

G.O. ....Mar. 1996

Name change to Susanville Casino in 1997. (The lady didn't know what month.)

Name change to Diamond Mt. Casino....Jan. 2002

Hope that helps.
