Arguably the most spectacular rock art site in the South West, the Great Gallery is the type site for Barrier Canyon Style (BCS) art. It was first recognized here as a unique artistic style. Rock art is notoriously hard to date and BCS art age estimates range from Archaic (4,000-8,000 BP) to pre Fremont (500 BCE-500 CE). The National Park Service has a free booklet on the archaeology of Horseshoe Canyon that puts the date for BCS production at around 2,000 BCE.
