Bryce Canyon, in southwestern Utah is a spectacular place (not actually a canyon) with unique formations called Hoodoos carved out by rain, melting snow, and frost. The different layers of sediment varies in erosion resistance hence the resulting shapes. The canyon is about 30 miles long, and a long time is needed to explore the place. Horse riding is very popular in season and horse riders can be seen in one of the photos which also adds scale to the photo.
If you plan to visit make sure that you explore the area and find a location from where to get a photo shortly after sunrise or before sunset. Warm sunlight should add brilliant hues to the already color rich landscapes.
