Grand Canyon National Park is a World Heritage Site.
Bryce Canyon National Park
At Bryce Canyon National Park, erosion has shaped colorful Claron limestones, sandstones, and mudstones into thousands of spires, fins, pinnacles, and mazes. Collectively called "hoodoos," these colorful and whimsical formations stand in horseshoe-shaped amphitheaters along the eastern edge of the Paunsaugunt Plateau in Southern Utah.
