1956 Map of Kapowsin

About this map

The Puyallup River and Nisqually River valleys dominate this 1956 mid-century landscape, revealing a region defined by hydroelectric power and timber transport. The infrastructure at Electron is particularly detailed, showing the Electron Flume, Electron Reservoir, and the complex Penstocks and Tramway system leading to the Powerhouse. This engineering network illustrates the early 20th-century push to harness glacial runoff for regional electricity. In the south, the rising waters of Alder Lake border the settlements of Elbe and Park Junction, where the Chicago Milwaukee St Paul and Pacific railroad tracks follow the river's edge. From the lakeside community of Kapowsin to the mountain gateway of Ashford, the map documents a transition from industrial activity to early alpine recreation at Voss Resort and Surprise Valley.
