Removal of one of the towers used to support the conveyor belt which delivered aggregate to the west side mix plant. The foundation level of Grand Coulee Dam is complete, and the river flows through diversion slots in the dam.
Structures which were to be inundated by the reservoir were removed before the lake started to fill. The photo appears to show the destruction of one of the piers which supported the Great Northern bridge across the Columbia at Marcus, Washington.
The “Government Town” in the foreground, and the “Contractor’s Town” across the river, in the background. Mason City, the contractor’s town, was named for Silas B. Mason.
