The plaque reads: "In 1892 Contra Costa County named Black Daimond Way, and maintained it as a road until 1982. (loacally it was also called Nnortonville Road.) Black Diamond Way became part of the Black Diamond Mt. Diablo Regional Trail in 1985.
Black Diamond District Coal mines operated from 1861 until circa 1900. Between 1867 and 1883 they produced over 100,000 tons annually. Coal was hauled to river landings by teams and rail.
Miners and families from Mt. Diablo coalfield towns crossed Mt. Diablo creek to enter Clayton for supplies, services and recreations. Inns and saloons outnumbered other establishments."
