In 1938, Mirl Simmons, of Susanville’s Eastmans Studios was one busy guy. He was busy filming and photographing the eight counties then that made up the Shasta-Cascade Wonderland Association. That association was preparing to display all the wonders the region possessed at the upcoming Golden Gate International Exposition to be held in San Francisco during 1939.
Early one morning in May 1938, Simmons made a journey to Secret Valley in hopes of capturing on film sage hens. What he found instead was a herd of co-operative antelope that he made a motion picture of instead.
