You don’t need a museum ticket to visit the Great Gallery at Canyonlands National Park, but you’ll want to bring your hiking boots. This remote archeological site in Utah is home to one of the most well known rock art collections in the country. Archaeologists believe that the pictographs here in Horseshoe Canyon (formerly known as Barrier Canyon) were produced sometime between 400 and 1100 CE, when nomadic hunter-gatherers roamed the desert. Pictured here is the Ghost Panel, named for about 20 life-sized figures that seem to hover above viewers.
