|Eastern Mojave Vegetation||Standard No. 1 Mine, San Bernardino County, California.|
Also known as an Excelsior, Bluegrass, and Copper Town Mine. The Excelsior was located in 1896 and produced copper with gold and silver between 1902 and 1908 from a skarn that contained magnetite, chalcopyrite, and scheelite. Before 1905, ore from the Standard No. 1 was hauled by wagon to a smelter at Needles. Rail service was established to Cima in 1905, and ore was then hauled by 16-horse-team wagons to rail cars bound for smelters in Salt Lake, Utah.
