Kumeyaay astronomy
Kumeyaay astronomy or cosmology (Kumeyaay: My Uuyow, "sky knowledge") comprises the astronomical knowledge of the Kumeyaay people, a Native American group whose traditional homeland occupies what is now Southern California in the United States and adjacent parts of northern Baja California in Mexico. A deeply rooted cosmological belief system was developed and followed by the Kumeyaay civilization based on this knowledge including the computing of time (Kumeyaay Mat’taam).
