I visited the town of Black Diamond, WA. It’s an old coal mining town. It’s a great country-styled town with a bakery, smoked meat shop, a great antique shop, and a historical museum.
A little bit of history for you: In the early 1880’s, the Black Diamond Coal CO. of CA was depleting its supplies and they faced moving their entire operation to a remote area in WA territory (WA wasn’t a state yet). A rich and plentiful seam of high grade coal in WA promised to keep miners busy for the next hundred years. The area provided all the timber they needed to brace the mine tunnels and to build a town for the families and the miners. They called the area, Black Diamond. After WWI, oil gradually replaced coal as the fuel of choice for heating and transportation. Some historic buildings still remain.
