Comb Ridge
In southern Utah and northern Arizona there exists a geologic formation known as a monocline, an uplift in the earth's surface that rises gently from a flat surface and then drops off a steep face off the top. One of the most famous of these anywhere in the US is located in Southern Utah and Northern Arizona, called "Comb Ridge". This spine runs 100 miles through the brilliant red deserts of the Colorado Plateu, and is a major landmark in the area. The spine is sinuous and beautiful, contorting into shapes that seem bizarre and unnatural.
