In December, 1865, Idaho's Governor Caleb Lyon of Lyonsdale set off a wild rush to Diamond Gulch, visible a few miles west of here, with a story that was too good to be true. He told miners in Silver City that a prospector had given him some priceless diamonds from that area. Enough gems of interest to rockhounds were found there to maintain a diamond frenzy that winter. A similar excitement followed in 1892, but no actual diamonds ever were recovered in Diamond Gulch.
