Hoover Dam

Hoover Dam is an engineering wonder of the world just 35 miles southeast of Las Vegas. Formerly named Boulder Dam, this historic man-made creation tamed the mighty Colorado River and created North America's largest man-made lake, Lake Mead. The 726-foot-high, arch-gravity dam is 660 feet thick and forever changed the face of the western United States. On-site tours of the dam are available to the public throughout the year.  The Bureau of Reclamation has conducted tours through the Hoover Dam and powerplant since 1937. Today, close to 1,000,000 visitors a year take the tour and millions more drive across the dam.  The hard hat tour is definitely worth the trip!
