Description
Photograph of construction of Boulder Dam, showing the back side of the dam, ca.1930. Ladders and jagged staircases climb up the tall dam at center while frame-like structures of intertwining wood and metal beams lie at the bottom. The dam wall is striped with discolored panels as it extends from canyon wall to canyon wall. Wires also reach the distance of the canyon while other wires hang into the work site below.
