The Nampaweap petroglyph site is a large site in a basalt canyon next to Mount Trumbull. The name Nampaweap is a Paiute phrase that means “Foot Canyon”. It’s probable this name refers to the canyon being a natural passageway
The symbols carved into the dark canyon walls come from the Ancestral Puebloan (Anasazi), Paiute, and Archaic cultures. Some of these petroglyphs could be as much as 10,000 years old.
