Footage from the documentary 'Monumental Vision - USA'. The location of Rogers' 'Rhythms of Life' site is on the Black Mesa, Yucca Valley, near Joshua Tree National Park in the Mohave Desert, California. 'Atlatl' is based on a 3,000-year-old Native American petroglyph of a spear thrower that Rogers saw on nearby rocky outcrops at Coyote Hole and also in the Rodman Mountains. 'Rhythms of Life' is constructed of light-colored stones providing contrast to the dark volcanic rock of Yucca Valley. The completion of the geoglyphs was celebrated with a Native American ritual, the Smoke
Ceremony, as well as traditional songs and dances.
