we had part one of the hoodoo homily in the afternoon, exploring the more remote viewpoints in the park. After a short dinner in camp, we went to the northern end of the park to see the sunset. We got out at Fairyland Point as the sun was disappearing over the horizon.
The reason Bryce "Canyon" is a cliff edge is the effect of headward erosion. The downdropped edge of the block slopes upwards to the west, so drainage was towards the Paria River to the east (that's hard to visualize the way I'm saying it. Look at the diagram above instead!). The erosion of the soft rocks of the Claron Formation formed a series of amphitheaters filled with the unique hoodoos that make Bryce Canyon National Park so spectacular.
