Cathedral Rock is a natural sandstone butte on the Sedona skyline and one of the most-photographed sights in Arizona. The rock formation is located in the Coconino National Forest in Yavapai County. The summit elevation of Cathedral Rock is 4,967 feet (1,514 m).
Mystical Slot Canyon is not far from Kanab, UT is also known as Red Canyon or Peek-A-Boo Canyon. The fantastic red sandstone walls with undulating striations provide unlimited photography
The description of this location within Tonto National Forest says it is used by kayakers. My recommendation is to update the description and mention it is used by photographers too.
