This camera worked nearly every day documenting all
phases of the construction. Pouring concrete is what people think of most
often when they think of Hoover dam but there were so many other phases of
construction that went on simultaneously with the pour. All the turbine
tunnels had to be built and placed. The turbines that drive the generators
are 115,000 horsepower each. The footage this camera shot covers an
incredible array of projects that went on at the dam site plus at the
railroad that was specially built for the project and several miles away at
the site where the aggregate for the concrete mix was mined.
