Glen Canyon Dam (AZ) (Images of America)

Constructed between 1956 and 1966 by the United States Bureau of Reclamation, Glen Canyon Dam on the Colorado River was a project of immense proportions. Even before the non-stop pouring of 5 million yards of concrete began, much work had to be accomplished. The town of Page, Arizona was established on a windswept mesa to house workers and their families, and the 1,028-foot Glen Canyon Bridge was built to carry men, materials, and equipment to the dam site. Though the dam has proven a controversial structure throughout its history, the massive undertaking of its construction was an undeniable triumph of ingenuity and determination.
