Sunrise and sunset make great photo opportunities in Bryce Canyon National Park, Utah, USA. For example, sunset spotlights eroded hoodoos in the Queen's Garden (one appears like a profile of Queen Elizabeth with gown). Bryce is actually not a canyon but a giant natural amphitheater created by erosion along the eastern side of the Paunsaugunt Plateau. The ancient river and lake bed sedimentary rocks erode into hoodoos by the force of wind, water, and ice. Photographs by Tom Dempsey.
