Residents of Horseshoe Canyon, formerly known as Barrier Canyon, execute wall paintings.
Barrier Canyon Style (BCS) rock art includes both pictographs and petroglyphs.
The gallery is a product of the Desert Archaic culture, a nomadic group of hunter-gatherers.
The panel in the so-called Great Gallery, which measures about two hundred feet (sixty-one meters) long and fifteen feet (4.6 meters) high, contains about twenty life-sized anthropomorphic images, the largest of which measures over seven feet (2.1 meters) tall.
Reproductions showing the haunting beauty of the paintings are in the Museum of Modern Art in New York and the Denver Natural History Museum.
