Zion National Park encompasses some 150,000 acres of wild canyon country east of St. George, Utah, including the narrow, multicolored Kolob Canyons to the north and many miles of largely impenetrable mountain wilderness. However, the vast majority of visitors come only to see Zion Canyon, probably the most immediately spectacular of the many geological wonders in Utah - sheer red and white sandstone cliffs tower up to 2,500 feet above the North Fork of the Virgin River, and gradually become closer together upstream until only 30 feet apart in places.
