One photo album illustrating the construction of the Grand Coulee Dam from 1933 to 1937. It includes photographs of the site before construction, the Columbia River diversion, blasting, "jackhammer men," driving steel piling, and general construction…
Cooling pipe. Water will be circulated through 2000 miles of it embedded in the dam to cool and shrink the concrete and thus facilitate grouting of construction joints.
Facilities for visitors. Some 200,000 visitors in 1936 inspected a model of the dam and from sheltered seats close to the work on each side of the river viewed the construction work and had it explained over a public address system.
Columbia River Diverted. Two cross-river cofferdams divert stream through low sections in west portion of dam while east portion is unwatered for preparation of foundation.
