No gallery anywhere in the Southwest is richer than the vast array of petroglyphs (nearly all of them Fremont) in Nine Mile Canyon, northeast of Price, Utah. In its forty-five-mile length, the number of panels on the canyon walls is estimated at around ten thousand, the number of individual images as at least one hundred thousand. Nine Mile, in fact, contains what is regarded by experts as “the largest concentration of rock art in North America.”
