The Holy Ghost pictograph is part of the larger Great Gallery Panel, which is over 200 feet in length. The Holy Ghost is 7 feet tall, the largest in Horseshoe Canyon, and one of the largest known anthropomorphs, of the Barrier Canyon Style (BCS), produced by Archaic Indians that inhabited Utah and the surrounding area for more than 7,000 years. At least 230 locations of Barrier Canyon art have been found to date, with researchers estimating there could be as many as 400.
