1. Transmission Lines Marker
Transmission lines are a visible link between these remote mountain lakes and densely populated urban areas. Gorge was the first of the Skagit power projects to go on line. On September 17, 1924, President Calvin Coolidge pressed a gold telegraph key in Washington, D.C., sending electricity from the Gorge Power House to Seattle, along lines hung from wooden poles.
Today high-capacity lines hang from metal towers and criss-cross the mountain scenery. As falling water turns huge turbines in the Upper Skagit power plants, the electricity generated travels in power lines along a portion of the North Cascades Highway.

Also see . . . Hydroelectric power from Skagit River reaches Seattle. During construction, the power lines had been used for a telephone system.
