Tucked away in the juniper-dotted canyons of the Grand Canyon-Parashant National Monument in northwestern Arizona next to Mount Trumbull lies one of the region's most extensive collections of rock art - the Nampaweap Petroglyphs. Meaning "foot canyon" in the Paiute language, the name probably refers to the canyon as a natural passageway of travel for the Paiute. Nampaweap contains thousands of petroglyphs etched into the boulders along a half-mile canyon stretch.
