Named for a geological formation, what 710-foot dam - built from 1956 to 1966 - was responsible for forming Arizona's popular tourist attraction Lake Powell?

Lake Powell is a massive lake that is over 550 feet at its deepest point. The lake is basically a giant canyon filled with clear water, ideal for outdoor recreation. The lake was created when Glen Canyon Dam was built in the 1950s, and is named for John Wesley Powell, famous for his 1869 boat expedition through the Grand Canyon.
