Grand Coulee Dam

Title

Grand Coulee Dam

Description

The Grand Coulee Dam is the largest dam on the Columbia River. The U. S. Bureau of Reclamation constructed the dam between 1934 and 1941. It is the largest hydroelectric power producer in the United States. Images in this collection are taken from a photo album showing the construction of Grand Coulee Dam from 1933 to 1937. The album includes photographs of the site before construction, the Columbia River diversion, blasting, "jackhammer men," driving steel pilling and general construction photographs. It also includes one photograph of the builder's quarters, Franklin D. Roosevelt at the dedication in 1934, and photograph of Governor Clarence D. Martin formally placing the first concrete in the dam in 1935. The photographer of this album is unknown, but the photographs are 8x10 images taken with a large format camera. The album also includes a map of the damsite.
