Description
Photograph of construction of Boulder Dam, showing construction on the top of the dam, ca.1930. A thick, metal frame stands on support platforms on the canyon wall to the left of the dam. A row of tires stands just behind the frame while large rings lean against the rock wall behind them with metal towers standing above. The lightly-colored dam stands on the right with a "Z"-shaped staircase climbing up the smooth wall. The far canyon wall can be seen in the background with a faint mountainside behind it.
