The hundreds of petroglyphs etched into the boulders and cliffs of Nine Mile Canyon may be one of the world's largest outdoor art galleries. They're the handiwork of the Fremont people, who lived in much of what is now Utah from AD 600 to 1300. The canyon also shelters the remnants of many early homesteads, stage stops, and ranches. However, the petroglyphs and pictographs are the main draws. It's important not to touch the fragile rock art because oils from your fingers can damage them. The drive spans about 100 miles round-trip, so plan a day to complete it. Bring water and a picnic, because there are no services. A brochure detailing significant sites is available at the Carbon County Visitors Center in Price. Without it, many panels will go unnoticed.
