The Towers of the Virgin include the Altar of Sacrifice (right) and The Sundial (left-center). These prominent cliffs of Early Jurassic-age Navajo Sandstone, which locally exceed 2000 feet, formed as the North Fork of the Virgin River carved Zion Canyon in the relatively short time span of the past 2 million years.
