"For time immemorial Snoqualmie Falls has been a sacred site to the Pacific Northwest's native people, a place whose thundering waters and soaring mists harbor deep spiritual power. In the 1880s, a young man gazed upon Snoqualmie Falls' magnificent, cascading flows and envisioned an entirely different kind of power. This is the story of the enterprising civil engineer and his remarkable quest to harness Snoqualmie Fall's energy and build the world's first completely underground hydropower plant, deep within the tower fall's basalt shoulder." -- back cover
