Zion National Park's unique geology features towering sandstone monoliths and canyons carved by the Virgin River over millions of years. The prominent Navajo Sandstone, remnants of ancient sand dunes, form the park's iconic cliffs. These cliffs, along with other layers of rock, display a fascinating history of uplift, tilting, and erosion, showcasing the Grand Staircase geological feature.
