Construction of Hoover Dam, 1933-1935

Originally called Boulder Dam, the Hoover Dam straddles the border of Arizona and Nevada. Construction began in 1933 and was completed two years later. Built with 3.2 million cubic yards of concrete, the dam is some 726 feet high, ranking 20th in the world for height. From 1939 to 1949 it was the worlds largest producer of hydroelectric power; today the dam generates some 4.2 billion kilowatt-hours of electricity annually. Lake Mead, the reservoir created by the dam, covers 247 square miles and is a major recreation area.

@ZX2ManDave Man, you got that right. even worse, they will be with their woman and call another man to change a flippin tire. they should go jump off a cliff.

[ZX2ManDave]

Look at the work those men are doing, dangling down the side of a cliff only supported by ropes while hammering away, these days most men cant even change the flat tire on their car, they have to call out a tow truck to do it for them.
