The major feature of the park is Bryce Canyon which, despite its name, is not a canyon but a giant natural amphitheater created by erosion along the eastern side of the Paunsaugunt Plateau. Bryce is distinctive due to geological structures called hoodoos, formed by wind, water, and ice erosion of the river and lake bed sedimentary rocks. The red, orange, and white colors of the rocks provide spectacular views. The rim at Bryce varies from 8,000 to 9,000 feet (2,400 to 2,700 m).
