Zion
Zion National Park, about 150 miles from Las Vegas in Utah, features spectacular canyons and rock formations. They resulted from upheavals of the earth and erosion by flowing water and frost.
Bryce Canyon
Further from Las Vegas is Bryce Canyon National Park, a 56-square-mile area of colorful cliffs created by erosion. Towering rocks worn to odd, sculptured shapes stand grouped in striking sequences.
