Glen Canyon Dam

In 1964, the Colorado River’s powerful flow was tamed with the construction of the Glen Canyon Dam, a colossal 710-foot-tall (216 meters) structure. The dam’s creation led to the formation of Lake Powell, stretching 186 miles (299 kilometers) and taking 17 years to reach its full capacity, making it the second-largest man-made lake in the United States. Today, the dam not only stands as an impressive engineering feat but also serves a vital role in providing hydroelectric power to the American West. Visitors can explore the dam’s visitor center and learn about its history and ongoing impact on the region.
