Grand Canyon-Parashant National Monument, Mojave County Arizona
Nampaweap is a very large petroglyph site in the Grand Canyon-Parashant National Monument. Hundreds of individual petroglyphs cover the face of a lava flow at the head of Nampaweap canyon. The canyon is a natural corridor from the Colorado River to the Ponderosa pine forest on Mt Trumbull and the wetland around Nixon Spring. There are a large variety of symbols represented at this site including the nearly universal anthropomorphic figures.
