Palmer Coking Coal Company (Palmer) is a family-owned and operated business incorporated in Durham on August 14, 1933. Our company no longer mines coal, though our roots run deep in King and Pierce Counties. Many have asked, “What does Palmer Coking Coal mean?” Palmer comes from the generally forgotten town of Palmer-Kanaskat (near Durham), located in east King County. Coking refers to a type of coal which could be partially “cooked” to extract impurities. Coal was the mineral we mined during the Great Depression, when thirty or more companies competing for market share in a declining industry. By selling good quality products, Palmer Coking Coal found favor with consumers and businesses in supplying Washington’s fuel needs.

During the 1950s Palmer acquired a land base which allowed expanded mining opportunities in Black Diamond, Ravensdale and Franklin. Diversification into other extractive products soon followed: red cinders, clay, silica, timber, sand, gravel, and topsoil. While our business has evolved to serve contemporary needs, we have always stayed true to the principles of our founders: Good Products – Good Prices – Good Service.
