Fairyland Loop Trail Professional Review and Guide
"The area below the rim of Bryce Canyon National Park is a fantasyland of strange and wonderful geologic formations. Stone spires and pinnacles with fanciful names like the “Chinese Wall” and “Seal Castle” surround the trails, making them delightful places to hike.
As the canyon rim erodes, new hoodoos are formed. They begin first as tall thin fins, then serrate to form pinnacles and spires. The colors are caused primarily by iron and manganese impurities in the rock that oxidize into colorful hues of red, pink, orange, yellow, and purple. The carving action is still continuing, and it is estimated that today the rim of Bryce Canyon is receding at the rate of about one foot in 65 years. In another hundred thousand years it will have receded by a third of a mile, and a whole new display of artwork will be ready for viewing in nature’s gallery."
