1949 Map of Black Diamond

About this map

The Green River carves a deep, winding path through this corner of King County, defining a landscape shaped by coal mining and timber. The industrial heart of the area is centered at Black Diamond, where a prominent Coal Mine and a local Cem reflect the settlement's heritage. To the north, the terrain transitions into a lake-rich plateau, featuring Lake Sawyer, Pipe Lake, and Lake Lucerne, where the Cherokee Bay Park and various Conference Grounds suggest a mid-century shift toward recreation.
