The Burrell C. Lawton Photograph Collection on the Hoover Dam depicts the construction of the Hoover (Boulder) Dam on the Colorado River near Las Vegas, Nevada from 1931 to 1934. The photographs primarily depict workers, construction equipment, and the progression of the dam's concrete structures. The photographs also depict construction of diversion tunnels, bridges, the gravel plant, the intake towers, and the concrete mixing plant.
