As pioneers explored and found their way across the vast continent of America, they were frequently stopped by poor or hostile environments such as the desert regions of Arizona and Nevada. 'Some 60 storeys high, and of a larger volume than the Great Pyramid at Giza ...'In the early 1900s, however, engineers began to realise that even here it would be possible to make the desert bloom, by building a dam across the Colorado River. Some 60 storeys high, and of a larger volume than the Great Pyramid at Giza, the Hoover Dam was soon to break all records. At the height of the depression of the 1930s, poverty-stricken workers on the dam, earning just a few dollars a day, died from horrific explosions, carbon monoxide poisoning and heat exhaustion as it slowly came to fruition. The chief engineer, Frank Crowe, did nevertheless get it built ahead of schedule and under budget - notching up one more extraordinary piece of evidence for the ingenuity and tenacity of man.
