Their spontaneous originality is breathtaking. Whereas organic designs, and those created by people, tend to be stereotyped in cases, or formally geometric, or repetitious and stylized, every design carved in rock is an original. In inorganic art there seems to be no duplication or repetition. Line flow and form, in rock, have limitless variations in three dimensions. Esthetic perfection in nature, as a concept, is hardly novel.
Most people recognize it in flowers, sunsets, mountains, the forms of animal life, etc.
I have always found esthetic pleasure in rock art of that type, and not only in form and texture. Colors of the rocks in the Enchanted Wilderness are so marvelous, as at Bryce, or Cedar Breaks, or Capitol Reef, or in The Needles-Salt Creek country, or myriad other places. Trying to describe erosional forms is very difficult for me. Particularly difficult to describe are intricately detailed sculptures, such as those at Bryce and Cathedral Valley, which are carved from layered rocks of varying thickness and differing resistance to erosion. In my personal lexicon, such forms represent the ineffable.
