Hoover Dam demonstrates a country's ability to construct a colossal project in the midst of many adverse situations. When its construction began in 1930, during the great depression, in a remote and rocky place filled with choking dust amidst brutal heat on a dangerous height, many of the workers died during the construction work. It is considered as one of the top ten Construction Achievement of the modern world and continues to draw a million visitors a year even after its seventy years of creation.
