Rainbow Point is the summit of the Grand Staircase. The geological evolution extends for about 150 miles from the peak where you are standing to the Grand Canyon. The rock formations exposed at Bryce Canyon are the Claron Formation. Relatively speaking, they are the youngest layer of the Grand Staircase. They were created 56 to 34 million years ago. In contrast, the exposed rocks in the 6,000 foot deep Grand Canyon range in age from 200 million to nearly two billion years. Between these two points, there are 24 unique formations within five major “steps.” Bryce Canyon is called the Pink Cliffs. The other four are the Grey, White, Vermillion and Chocolate Cliffs. No wonder they call this overlook Rainbow Point.
