Kasha-Katuwe was initially formed by volcanic eruptions over 6 million years ago that deposited layers of pumice, ash and tuff. Wind and water erosion caused the formation of the “Tent Rocks” (also known as Hoodoos). The erosion additionally created serpentine channels out of the boxed canyon that now serve as the visitor’s access route to the trail that leads up to the south rim overlook.
It’s a moderate climb up the 1.2 mile trail to the rim which is where you can see the view where the Panorama photo was taken.
