This undated file photo provided by Utah State University shows the Holy Ghost group of the Great Gallery, a striking Barrier Canyon-style rock painting in Horseshoe Canyon of southern Utah's Canyonlands National Park. Life-sized figures sketched into red rock cliffs in Canyonlands National Park were drawn 1,000 years more recently than what had long been believed, a team of Utah State University scientists discovered about the world-renowned rock art. The team used modern luminescence dating techniques to analyze when the art went up in what is known as the “Great Gallery” in southeastern Utah’s Horseshoe Canyon. The researchers believe the figures were created 1,000 to 2,000 years ago instead of the previously thought 2,000 to 4,000 years ago. The study suggests the drawings may have been done as man transitioned to a culture of farming and away from hunting and gathering, said David Whitley, one of the foremost experts on rock art in North America. The research becomes important in better understanding art known as Ancient Barrier Canyon-style paintings, which are usually shrouded in mystery, said Whitley, who was not involved in the study.
