This awesome site is the furthest from St. George on our list, but it made the list because it, like Little Black Mountain & Anasazi Ridge, is covered in the unique ancient rock art. Also, like the other sites, it is believed to be made by many different generations and cultures over thousands of years. This particular canyon is very popular and mysterious because of its alignment with the sun. It is believed to have many carvings related to the seasons, that interplay with the sunlight and its shadows to give them religious, ceremonial, or a calendar-type significance.
