History & History Related Items
Black Diamond was established over a hundred years ago, when coal was discovered here. Coal mining began around the 1880's. The town was named a few years later for the Black Diamond Coal Company of California. By 1895, the company was the major developer for coal in the area. At its peak around 1900, the town had around 3,500 people, many of which worked in the industry in some way. The coal was moved to the Seattle area via the railroad. After World War I, the town shut down its coal operations. The city was incorporated in 1959. At present, the area is experiencing rapid growth. Black Diamond is known for its pure, stable water supply.
