Time Changes The Land

Year Published: 1964

Complete Record: The Zion-Bryce Region in Southern Utah provides the opportunity to follow 200,000,000 years of continuous geological change. Exposed layers of earth reveal alternating cycles of land building, volcanic activity, and erosion by wind, water, and ice. Today this area is a wonderland of deep canyons, massive cliffs, and wind-carved spires. Unusual formations and color-drenched layers of rock and sandstone trace a history that began in the Mesozoic or fourth great geologic era.
