There are many interesting ancient rock art images along "Anasazi Ridge" in Santa Clara, just west of St. George. The ridge overlooks the Santa Clara River.
Most of the time rock art is found on vertical panels of stone. There is some of that here, but you will also find images on horizontal panels. In some spots, if you are not careful you will step on ancient images.
A popular mountain bike trail follows the ridge and many of the images can be seen from that trail. Other images can be found if you search for panels just under the ridge, on the river side.
Part of this area is also known as "Land Hill." Read more about the rock art.
