About this map

Black Diamond and its neighboring settlement Morganville serve as the industrial anchors for this King County landscape, which was actively shaped by coal mining and timber operations at mid-century. The Northern Pacific and Coast Pacific railroads provide the essential transport corridors, winding through a terrain defined by glacial lakes and the deeply incised path of the Green River. Along the river’s southern banks, the Flaming Geyser Park Swimming Pool marks a significant recreational site near the small settlement of Kummer.

Inland, the map reveals a mosaic of water bodies including Lake Sawyer, Lake Morton, and Pipe Lake, alongside the northern edge of the Muckleshoot Indian Reservation. Evidence of early local infrastructure appears in labels for a Coal Mine, a Sawmill, and the Cem west of Black Diamond, offering precise data points for genealogical research into the families that supported the region's resource-based economy.
