The Desert Speaks
Shadows of the Ancients
Season 13
Episode 9
Archaeological evidence suggests that the ancestral Pueblo Indians (Anasazi) marked astronomical events, perhaps as guides or records. Rock art and architecture throughout the Four Corners area were carefully placed so that beams of sunlight would interact with rock images on important seasonal days such as equinoxes and solstices, marking the days with remarkably high precision.
